Description
FIELD OF THE INVENTION
[0001] The present invention relates to a slide rail structure, and
more particularly to a slide rail structure for fixing a power
supply to a machine frame.
BACKGROUND OF THE INVENTION
[0002] When a conventional power supply is to be placed in a
machine frame, the power supply is first placed in the
accommodating space of the machine frame, and then L-shaped fixing
plates are fixed to the side walls of the rear of the power supply.
The other ends of the L-shaped fixing plates are located at a rear
position of the machine frame and extend toward both sides of the
machine frame. The other ends of the L-shaped fixing plates are
locked to the rear end of the machine frame, so that the power
source can be stably disposed in the machine frame and won't sway
left and right.
[0003] However, since the L-shaped fixing plates of the power
supply are locked to the rear end of the machine frame from the
rear, it is very inconvenient in operation. The front of the power
supply is not fixed. During the process of moving the machine, the
front of the power supply is easy to sway and is unstable and even
hits the side walls of the machine frame to cause damage.
Accordingly, the inventor of the present invention has devoted
himself based on his many years of practical experiences to solve
these problems.
SUMMARY OF THE INVENTION
[0004] The primary object of the present invention is to provide a
slide rail structure for fixing a power supply to a machine frame.
The slide rail structure is used to prevent the power supply from
moving left and right in the machine frame, thereby enhancing the
stability of the power supply in the machine frame.
[0005] In order to achieve the aforesaid object, a slide rail
structure for fixing a power supply to a machine frame is provided.
The slide rail structure is disposed between the machine frame and
the power supply to guide the power supply to be mounted into the
machine frame. The machine frame includes at least two longitudinal
left racks and at least two longitudinal right racks at two sides
thereof. The slide rail structure comprises two inner slide rails
and two outer slide rails. One inner slide rail is laterally fixed
to the two left racks, and the other inner slide rail is laterally
fixed to the two right racks. Each of the inner slide rails
includes a bottom plate and a pair of side plates extending
laterally along a top edge and a bottom edge of the bottom plate. A
U-shaped groove with an opening facing inward is defined between
the bottom plate and the pair of side plates. Two outer slide rails
are laterally locked to two sides of the power supply,
respectively. Each of the outer slide rails includes a bottom plate
and a pair of side plates extending laterally along a top edge and
a bottom edge of the bottom plate. A U-shaped groove with an
opening facing outward is defined between the bottom plate and the
pair of side plates. The outer slide rails are slidably connected
to the corresponding inner slide rails and slide in a same
direction to form a supporting function.
[0006] The power supply provided by the invention is fixed to the
slide rail structure of the machine frame, and the guiding plates
of the inner slide rail guide the outer slide rail, so that the
inner slide rail smoothly slides into the U-shaped groove of the
outer slide rail, and the inner slide rail is slidably connected to
the outer slide rail to slide in the same direction and to form a
supporting function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] Embodiments of the present invention will now be described,
by way of example only, with reference to the accompanying
drawings.
[0015] As shown in FIG. 1, FIG. 3 and FIG. 4, the present invention
discloses a slide rail structure 30 for fixing a power supply 10 to
a machine frame 20. The slide rail structure 30 is disposed between
the machine frame 20 and the power supply 10 to guide the power
supply 10 to be mounted into the machine frame 20. Two sides of the
power supply 10 are provided with a plurality of screw holes 11.
The machine frame 20 includes at least two longitudinal left racks
21 and at least two longitudinal right racks 22 at two sides
thereof. An installation space is defined between the two left
racks 21 and the two right racks 22. The two left racks 21 and the
two right racks 22 are provided with a plurality of spaced screw
holes 23, respectively. The slide rail structure 30 comprises two
inner slide rails 40 and two outer slide rails 50.
[0016] One inner slide rail 40 is laterally fixed to the two left
racks 21, and the other inner slide rail 40 is laterally fixed to
the two right racks 22. The two inner slide rails 40 are parallel.
Each of the inner slide rails 40 includes a bottom plate 41 and a
pair of side plates 42 extending laterally along a top edge and a
bottom edge of the bottom plate 41. A U-shaped groove 43 with an
opening facing inward is defined between the bottom plate 41 and
the pair of side plates 42. The bottom plate 41 is provided with a
plurality of screw holes 44. Fastening members 45 are inserted
through the screw holes 44 of the bottom plate 41 and the
corresponding screw holes 23 of the left racks 21 and the right
racks 22, so that the two inner slide rails 40 are screwedly
connected to the two left racks 21 and the two right racks 22 at
predetermined positions, respectively. The bottom plate 41 is
provided with a stop plate 46 relative to a front end of the power
supply 10. The stop plate 46 is perpendicular to the bottom plate
41. The stop plate 46 is provided with a rectangular hole 47 for
insertion of a limiting piece 56 of the corresponding outer slide
rail 50. Front ends of the pair of two side plates 42 have guiding
plates 48 inclining inwardly. The guiding plates 48 are guiding
slopes for guiding the outer rails 50.
[0017] The two outer slide rails 50 are laterally locked to the two
sides of the power supply 10, respectively. Each of the outer slide
rails 50 includes a bottom plate 51 and a pair of side plates 52
extending laterally along a top edge and a bottom edge of the
bottom plate 51. A U-shaped groove 53 with an opening facing
outward is defined between the bottom plate 51 and the pair of side
plates 52, so that the outer slide rails 50 are slidably connected
to the corresponding inner slide rails 40. The bottom plate 51 is
provided with a plurality of screw holes 54. Fastening members 55
are inserted through the screw holes 54 of the bottom plate 51 and
the corresponding screw holes 11 of the power supply 10, so that
the two outer slide rails 50 are screwedly connected to the two
sides of the power supply 10. The power supply 10 is slidably
disposed between the two outer slide rails 50. Further, the bottom
plate 51 is provided with a limiting piece 56 corresponding to the
rectangular hole 47 of the inner slide rail 40 relative to a rear
end of the power supply 10. The limiting piece 56 has a trapezoid
shape.
[0018] Referring to FIG. 2 and FIG. 5. First, when the power supply
10 is placed in the machine frame 20, the user only needs to push
the power supply 10 into the installation space, aligning the
limiting pieces 56 of the outer rails 50 with the guiding plates 48
of the inner sliding rails 40. At this time, the outer slide rails
50 can be guided to the proper position of the installation space
by the guiding plates 48, so that the inner slide rails 40 can be
smoothly slid in the U-shaped grooves 53 of the outer slide rails
50, and the side plates 42 of the inner slide rails 40 are abutted
against the side plates 52 of the outer slide rails 50.
[0019] Referring to FIG. 5 to FIG. 7, the power supply 10 is
further pushed inward towards the installation space, so that the
limiting pieces 56 of the outer slide rails 50 are inserted into
the rectangular holes 47 of the stop holes 46 of the inner slide
rails 40. The inner slide rails 40 and the outer slide rails 50 are
engaged with each other to form a blocking function, so that the
inner slide rails 40 are completely accommodated in the U-shaped
grooves 53 of the outer slide rails 50, respectively. Thereby, the
power supply 10 does not sway in the machine frame 20, and the
stability of the power supply 10 in the machine frame 20 can be
enhanced.
[0020] It is to be noted that, as shown in FIG. 1, the front end of
the power supply 10 is provided with a panel 12. The panel 12 abuts
against the left rack 21 and the right rack 22 to hold the power
supply 10, so that the damage of the power supply 10 caused by the
sway of the machine frame 20 is avoided, and the stability of the
power supply 10 in the machine frame 20 is further enhanced. A
handle 13 is fixed on either side of the panel 12. The handle 13 is
generally U-shaped. The user can take out the power supply 10 or
put it into the machine frame 20 through the handles 13, which is
faster and more convenient for use.
[0021] Although particular embodiments of the present invention
have been described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the present invention. Accordingly, the
present invention is not to be limited except as by the appended
claims.
