Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention relates to a rail device for
extracting computer equipment, and more particularly to a rail
device, an interior and an exterior of which can be gliding, such
that it can be quickly and conveniently fixed on a rack assembly of
different specification.
[0003] (b) Description of the Prior Art
[0004] Referring to FIG. 8, a typical example of a conventional
rail device for extracting computer equipment is composed of an
outer rail A which is glidingly connected with an inner rail B. The
inner rail B is then screwed with a fixing member C. Referring to
FIG. 9, a size of distance between a front and a rear vertical
racks E1, E2 of a rack assembly D is measured first, and then the
outer rail A, the inner rail B, and the fixing member C are
pre-assembled according to the correctly measured size, such that
the assembly length of outer rail A, inner rail B, and fixing
member C is equal to the distance between the front and rear
vertical racks E1, E2. Next, after accomplishing the assembling, a
fixing end A1 of the outer rail A is fixed on the front vertical
rack E1, and the fixing member C is fixed on the rear vertical rack
E2. This conventional technique is provided with the following
shortcomings in implementation: [0005] (1) The size of distance
between the front and rear vertical racks E1, E2 should be
measured, and the outer rail A, the inner rail B, and the fixing
member C should be pre-assembled exterior to the rack assembly D
before being installed on the front and rear vertical racks E1, E2,
thereby wasting a lot of implementation time and causing an
inconvenience in implementation. [0006] (2) As the extraction rail
is assembled from the outer rail A, the inner rail B, and the
fixing member C, a lot of assembly parts are required, and
mechanical strength is inferior. [0007] (3) There is only a pillar
F between the outer rail A and the inner rail B for supporting.
Therefore, when the inner rail B is gliding with respect to the
outer rail A, stability, mobility, and mechanical strength of
horizontal displacement are inferior.
SUMMARY OF THE INVENTION
[0008] The primary object of present invention is to provide a rail
device for extracting computer equipment, such that an assembly
member of an inner rail and an outer rail can be quickly and
conveniently installed on a rack assembly.
[0009] Another object of the present invention is to provide a rail
device for extracting computer equipment, such that an entire
assembly member of the inner rail and the outer rail is provided
with enhanced mechanical strength.

the technological methods of the invention herein, the brief

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] Referring to FIGS. 1 to 3, the present invention is to
provide a rail device for extracting computer equipment, including
an outer rail 10, an outer end of which is provided with a front
fixing part 12, and an interior of which is formed with a main slot
14 having a central indentation 16 in a middle of bottom thereof,
with a fixing pillar 161 being located at the central indentation
16, and with gliding slots 17 being formed at sides of the central
indentation 16; and an inner rail 20, which is a long plate, a rear
end of which is provided with a rear fixing part 24, and an
interior of which is formed with a main slot 25 having a long
through-hole 22 on a bottom surface thereof, with a rear stopping
part 222 being located on the long through-hole 22, with at least
more than one pillar 26 being fixed on a back surface of the inner
rail 20 to be glidingly transfixed into the gliding slots 17 of
outer rail 10, and with the fixing pillar 161 on the outer rail 10
being glidingly transfixed into the long through-hole 22.
[0021] The inner rail 20 can be glidingly displaced in the main
slot 14, the long through-hole 22 is glidingly displaced with the
fixing pillar 161 as a guiding rod, the rear stopping part 222 is
abutted (stopped) on the fixing pillar 161, and the pillars 26 on
the inner rail 20 can be glidingly displaced in the gliding slots
17.
[0022] Referring to FIG. 1, the outer rail 10 is formed into an
integral body by riveting an outer casing 101 and an inner casing
102, and the gliding slots 17, the front fixing part 12, and the
central indentation 16 are installed on the inner casing 102,
wherein an end of the gliding slot 17 is provided with a stopping
part 171, and the fixing pillar 161 is fixed on the central
indentation 16.
[0023] Referring to FIG. 5, the front fixing parts 12 of the two
outer rails 10 are fixed on two rear beams 52 of a rack assembly
50, respectively; whereas, the rear fixing parts 24 of the inner
rails 20 are fixed on two front beams 54 of the rack assembly 50,
respectively.
[0024] Referring to FIG. 5, the main slots 25 of inner rails 20 are
glidingly connected with inner gliding plates 32 which are fixed at
two sides of computer equipment 30 respectively, and can be
glidingly displaced in the main slots 25 of inner rails 20.
[0025] Referring to FIG. 6 and FIG. 7, top rings 261, 162 of larger
outer diameters are located above the pillars 26 fixed on the inner
rails 20, and above the pillars 161 of outer rails 10.
[0026] Referring to FIG. 1, an outer rail 10 is formed by riveting
an outer casing 101 and an inner casing 102; therefore its entire
mechanical strength can be enhanced. Two pillars 26 are shuttling
in gliding slots 17 at two sides. Referring to FIG. 7, top rings
261 are located on wall surfaces of the gliding slots 17; therefore
when an inner rail 20 is glidingly displaced in a main slot 14, two
pillars 26 are gliding along the two parallel gliding slots 17.
Referring to FIG. 6, the other fixing pillar 161 can be gliding
relatively to a long through-hole 22; therefore when the inner rail
20 is gliding on the outer rail 10, a gliding motion can be more
stable, an agility of the gliding can be improved, and mechanical
strength can be enhanced, with a support of three pillars 161, 26
(as shown in FIG. 4).
[0027] Referring to FIG. 6, the fixing pillar 161 is provided with
the top ring 162 of larger outer diameter. The top ring 162 is
located at a rim of the long through-hole 22, such that there will
be no left and right displacements between the inner rail 20 and
the outer rail 10; that is, when the inner rail 20 is glidingly
displaced in the main slot 14, a larger gap will not be formed.
[0028] Referring to FIG. 7, the two pillars 26 are provided with
the top rings 261 larger outer diameters. The two top rings 261 are
located on wall surfaces of the two gliding slots 17, which will
further reduce the gliding gap between the inner rail 20 and the
outer rail 10; that is, when the inner rail 20 is glidingly
displaced in the main slot 14, a larger gap will not be formed,
thereby increasing a closeness of gliding between the inner rail 20
and the outer rail 10.
[0029] Referring to FIG. 5, in implementation, the glidingly
assembled inner rail 20 and outer rail 10 are adjusted for a
straight distance between a front beam 54 and a rear beam 52, such
that the front fixing part 12 can be easily contacted with the rear
beam 52, and the rear fixing part 23 can be easily contacted with
the front beam 54. Next, by locking with bolts 55 (as shown in FIG.
3), the assembly member of outer rail 10 and inner rail 20 can be
quickly fixed on a rack assembly 50. Computer equipment 30 can be a
computer host or a server, and the inner gliding plates 32 fixed at
two sides thereof can be glidingly transfixed into the main slots
25 of inner rails 20. By pulling or pushing the computer equipment
30, the two gliding plates 32 can be gliding in the main slots 25,
and the computer equipment 30 can be pulled out of or pushed into
the rack assembly 50. At this time, three pillars 161, 26 are
supported and positioned into the two gliding slots 17 and the long
through-hole 22, respectively. Therefore, the inner rail 20 can be
firmly assembled with the outer rail 10, which can be sustained
with larger moment of force.
[0030] Accordingly, in the present invention, there is no need to
measure the distance between the front beam 54 and the rear beam
52, and the inner rail 20 and the outer rail 10 can be quickly
locked and positioned.
[0031] It is of course to be understood that the embodiments
described herein is merely illustrative of the principles of the
invention and that a wide variety of modifications thereto may be
effected by persons skilled in the art without departing from the
spirit and scope of the invention as set forth in the following
claims.
