Description
FIELD OF THE INVENTION
[0001] The present invention relates to a waterproof mechanism, and
more particularly to a waterproof mechanism having multiple
waterproof seals to enhance waterproof performance and achieve
excellent waterproof effect.
BACKGROUND OF THE INVENTION
[0002] Please refer to FIGS. 1A, 1B and 1C. A conventional
waterproof mechanism 1 includes a waterproof rubber ring 10, a
board body 13 and a seat body 15. The seat body 15 includes a first
receiving space 151 and a second receiving space 152. A platform
154 is formed at the junction between the first and second
receiving spaces 151, 152. An upright sidewall 155 extends from the
platform 154 to surround and define the second receiving space 152.
The waterproof rubber ring 10 is disposed in the second receiving
space 152. The waterproof rubber ring 10 is formed with a
perforation 101 in communication with the first receiving space
151. The waterproof rubber ring 10 has an inner periphery and an
outer periphery. The inner periphery is formed with a connection
channel 103 for connecting with the board body 13. The outer
periphery is leaned against the sidewall 155. A bottom section of
the waterproof rubber ring 10 abuts against the platform 154 as a
waterproof seal 16 (as shown in FIG. 1C).
[0003] In the case that external water/vapor or liquid infiltrates
through the gap between the sidewall 155 of the seat body 15 and
the outer periphery of the waterproof rubber ring 10, the
waterproof seal 16 of the waterproof mechanism 1 is able to stop
the water/vapor or liquid from infiltrating into the first
receiving space 151 of the waterproof mechanism 1. Accordingly, the
waterproof mechanism 1 can provide a waterproof effect.
[0004] However, the conventional waterproof mechanism 1 can only
provide a limited waterproof effect. This is because that due to
the weight of the board body 13, a downward pressing force is
applied to the waterproof rubber ring 10. In this case, no
component force directed to the sidewall 155 is applied to the
outer periphery of the waterproof rubber ring 10. Therefore, no
additional waterproof seal is provided between the outer periphery
of the waterproof rubber ring 10 and the sidewall 155 to enhance
the waterproof effect. Under such circumstance, the conventional
waterproof mechanism 1 has only one single waterproof seal 16,
(that is, the bottom section of the waterproof rubber ring 10 that
abuts against the platform 154), for preventing the water/vapor or
liquid from infiltrating into the waterproof mechanism 1. Once the
water/vapor or liquid infiltrates through the waterproof seal 16,
the water/vapor or liquid can infiltrate into the first receiving
space 151 without being stopped by any other protection means (such
as other waterproof seal). As a result, an article received in the
first receiving space 151, (such as an electronic product, a 3C
product, an LED product, a product likely to become damp or the
like) may be damped with the water/vapor or liquid.
[0005] According to the aforesaid, the conventional waterproof
mechanism has the following shortcomings: [0006] 1. The waterproof
effect of the conventional waterproof mechanism is poor. [0007] 2.
The conventional waterproof mechanism only has one single
waterproof seal. [0008] 3. The conventional waterproof mechanism
has poor waterproof performance.
SUMMARY OF THE INVENTION
[0009] A primary object of the present invention is to provide a
waterproof mechanism having excellent waterproof effect.
[0010] A further object of the present invention is to provide the
above waterproof mechanism having multiple waterproof seals for
enhancing waterproof performance.
[0011] To achieve the above and other objects, the waterproof
mechanism of the present invention includes: a board body; a seat
body having a first receiving space and a second receiving space in
communication with the first receiving space, the second receiving
space being longer and wider than the first receiving space,
whereby a platform is formed at a junction between the first and
second receiving spaces, an inclined sidewall extending from the
platform to surround and define the second receiving space; and a
waterproof rubber ring disposed in the second receiving space in
tight abutment with the platform. The waterproof rubber ring is
formed with a perforation in communication with the first receiving
space. The waterproof rubber ring has an inner periphery defining
the perforation and an outer periphery leaned against the inclined
sidewall. The inner periphery is formed with a connection channel
for connecting with the board body. The outer periphery is formed
with a protrusion section protruding from the outer periphery to
the inclined sidewall in abutment therewith. The waterproof
mechanism of the present invention has multiple waterproof seals to
enhance waterproof performance and achieve excellent waterproof
effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] Please refer to FIGS. 2, 3 and 4A. According to a preferred
embodiment, the waterproof mechanism 2 of the present invention
includes a board body 20, a seat body 22 and a waterproof rubber
ring 24. The seat body 22 has a first receiving space 221 for
receiving an article (such as an electronic product, a 3C product,
an LED product, a product likely to become damp, a communication
product or the like). The seat body 22 further has a second
receiving space 222 positioned above the first receiving space 221
in communication therewith. The second receiving space 222 is
longer and wider than the first receiving space 221, whereby a
platform 223 is formed at the junction between the first and second
receiving spaces 221, 222. An inclined sidewall 224 extends from
the platform 223 to surround and define the second receiving space
222. Please refer to FIG. 4A, which is a sectional assembled view
of the preferred embodiment of the present invention. The platform
223 is formed as a step section of the seat body 22.
[0021] The waterproof rubber ring 24 is disposed in the second
receiving space 222 in tight abutment with the platform 223. The
waterproof rubber ring 24 is formed with a perforation 241 in
communication with the first receiving space 221. The waterproof
rubber ring 24 has an inner periphery 243 defining the perforation
241 and an outer periphery 244 leaned against the inclined sidewall
224. The inner periphery 243 is formed with a connection channel
2431 for connecting with the board body 20. The outer periphery 244
is formed with a protrusion section 245 protruding from the outer
periphery 244 to the inclined sidewall 224 in abutment therewith.
The protrusion section 245 has at least one first protrusion flange
2451 and at least one second protrusion flange 2452. The first and
second protrusion flanges 2451, 2452 are formed on the outer
periphery 244 in immediate adjacency to each other (not shown) or
at intervals (as shown in FIG. 4A).
[0022] In addition, in accordance with the demands of appearance
and waterproof effect of the waterproof mechanism 2, the outer
periphery 244 of the waterproof rubber ring 24 can be designed with
an inclination equal to or unequal to the inclination of the
inclined sidewall 224. That is, the outer periphery 244 can be
parallel to the inclined sidewall 224 and have an inclination equal
to the inclination of the inclined sidewall 224 as shown in FIG.
4A. Alternatively, the outer periphery 244 can be unparallel to the
inclined sidewall 224 and have an inclination unequal to the
inclination of the inclined sidewall 224. In this embodiment, the
outer periphery 244 has an inclination equal to the inclination of
the inclined sidewall 224 for illustration purposes only.
[0023] Referring to FIG. 4A as well as FIG. 3, the first protrusion
flange 2451 protrudes from the outer periphery 244 to the inclined
sidewall 224. The first protrusion flange 2451 has the
configuration of a semicircle, a semi-ellipse or any other suitable
geometric pattern. The first protrusion flange 2451 tightly abuts
against the inclined sidewall 224 as a first waterproof seal 26 for
hindering (or stopping) external water/vapor or liquid from
infiltrating into the waterproof mechanism 2. Due to the weight of
the board body 20, a downward pressing force is applied to the
waterproof rubber ring 24. In this case, a downward pressing force
is simultaneously applied to the first protrusion flange 2451 of
the waterproof rubber ring 24 to make the first protrusion flange
2451 tightly abut against the inclined sidewall 224 to form the
first waterproof seal 26.
[0024] The second protrusion flange 2452 is positioned below the
first protrusion flange 2451 and protrudes from the outer periphery
244 to the inclined sidewall 224. The second protrusion flange 2452
has the configuration of a semicircle, a semi-ellipse or any other
suitable geometric pattern. The second protrusion flange 2452
tightly abuts against the inclined sidewall 224 as a second
waterproof seal 27 for hindering (or stopping) external water/vapor
or liquid from infiltrating into the waterproof mechanism 2. In
similarity to the first waterproof seal 26, due to the weight of
the board body 20, a downward pressing force is applied to the
second protrusion flange 2452 of the waterproof rubber ring 24 to
make the second protrusion flange 2452 tightly abut against the
inclined sidewall 224 to form the second waterproof seal 27.
[0025] The first protrusion flange 2451 protrudes from the outer
periphery 244 by a protrusion length. The second protrusion flange
2452 also protrudes from the outer periphery 244 by a protrusion
length. The protrusion length of the first protrusion flange 2451
is larger than or equal to the protrusion length of the second
protrusion flange 2452. In the case that the inclination of the
outer periphery 244 is equal to the inclination of the inclined
sidewall 224, the protrusion length of the first protrusion flange
2451 is equal to the protrusion length of the second protrusion
flange 2452 (as shown in FIG. 4A). In the case that the inclination
of the outer periphery 244 is unequal to the inclination of the
inclined sidewall 224, the protrusion length of the first
protrusion flange 2451 will be larger than the protrusion length of
the second protrusion flange 2452 (as shown in FIG. 4B).
[0026] Furthermore, a bottom section of the waterproof rubber ring
24 tightly attaches to and abuts against the platform 223 as a
third waterproof seal 28. In similarity to the first and second
waterproof seals 26, 27, due to the weight of the board body 20, a
downward pressing force is applied to the waterproof rubber ring 24
to make the bottom section thereof tightly abut against the
platform 223 to form the third waterproof seal 28. The third
waterproof seal 28 also serves to hinder external water/vapor or
liquid from infiltrating into the waterproof mechanism 2.
[0027] When the waterproof mechanism 2 is placed in an environment
where external water/vapor or liquid is likely to infiltrate into
the waterproof mechanism 2, the first waterproof seal 26 of the
waterproof rubber ring 24 serves to first stop (or hinder) external
water/vapor or liquid from infiltrating into the waterproof
mechanism 2. In case that the external water/vapor or liquid
unexpectedly infiltrates through the first waterproof seal 26, the
second and third waterproof seals 27, 28 will sequentially hinder
the water/vapor or liquid from further infiltrating into the
waterproof mechanism 2. Accordingly, the article received in the
first receiving space 221 is protected from being damped with the
water/vapor or liquid. The waterproof mechanism 2 of the present
invention has multiple waterproof seals to enhance waterproof
performance and achieve excellent waterproof effect.
[0028] According to the aforesaid, the waterproof mechanism of the
present invention has the following advantages over the prior art:
[0029] 1. The waterproof mechanism of the present invention is able
to provide excellent waterproof effect. [0030] 2. The waterproof
mechanism of the present invention has better waterproof
performance. [0031] 3. The waterproof mechanism of the present
invention has multiple waterproof seals.
[0032] The above embodiments are only used to illustrate the
present invention, not intended to limit the scope thereof. It is
understood that many changes and modifications of the above
embodiments can be made without departing from the spirit of the
present invention. The scope of the present invention is limited
only by the appended claims.
