The slide rail assembly disclosed therein does not have a slide rail reinforcement structure. For the situation of no reinforcing structure for the slide rail assembly, there is an Adjustable reinforcing slide rail assembly as disclosed in U.S. patent publication No. u.s.2006/0152115 a1, which includes a fixed slide rail (fixed slide rail 22) having a wall with an outer surface, and two ends of the fixed slide rail are respectively mounted on a pair of vertical posts of a rack (rack) by a mounting element (mounting element 26, 40); the rail assembly further includes a reinforcing member (32) attached to the outer surface of the wall of the fixed rail, and a mounting bracket (34) slidably attached to the reinforcing member.
While fig.1 and fig.8 of the U.S. patent publication disclosed by Dubon show that the reinforcing member (32) can reinforce the fixed rail (22), the combination of the reinforcing member (32) and the mounting bracket (34) connected to the fixed rail (22) increases a considerable width, so that when such a telescopic rail assembly is mounted in a rack (rack) in a pair manner and at a corresponding position, the space in the rack is limited, and the reinforcing assembly structure with such a large width is not suitable for use, which increases the difficulty of mounting the rail assembly and the rack in a matching manner, and hinders industrial utilization.
Therefore, in view of the disadvantages of the prior art, there is a need to provide a better design to improve the disadvantages.

As shown in fig. 3, the first rail 22 has a first upper wall 28, a first lower wall 30, and a first side wall 32 connected between the first upper wall 28 and the first lower wall 30, and the first upper wall 28, the first lower wall 30, and the first side wall 32 together define a first channel 34. In a preferred embodiment, the front end of the first side wall 32 of the first rail 22 has at least one first engaging feature 36, the at least one first engaging feature 36 is a protrusion, for example, the at least one first engaging feature 36 has an inclined portion 38 and a blocking portion 40 located at a high end of the inclined portion 38. Preferably, an upper supporting bar 29 is disposed inside the first upper wall 28 of the first rail 22. A lower support bar 31 is provided inside the first lower wall 30 of the first rail 22. The first upper wall 28 of the first rail 22 is provided with a first notch 28a, and the upper supporting bar 29 at the first notch 28a is also provided with a second notch 29 a. As shown in fig.1, when the second rail 24 is located at a predetermined extending position relative to the first rail 22, the first notch 28a and the second notch 29a correspond to one of the holes 68 of the second rail 24 for mounting one of the mounting members 18 of the chassis 12.
As shown in fig. 2 and 4, the second rail 24 is capable of moving in the first channel 34 of the first rail 22, the second rail 24 has a second upper wall 42, a second lower wall 44, and a second side wall 46 connected between the second upper wall 42 and the second lower wall 44, the second side wall 46 of the second rail 24 has an inner side 48a and an outer side 48b, and the inner side 48a corresponds to the first side wall 32 of the first rail 22.
As shown in fig. 2 and 5, the third rail 26 has a third upper wall 50, a third lower wall 52, and a third side wall 54 connected between the third upper wall 50 and the third lower wall 52, and the third upper wall 50, the third lower wall 52, and the third side wall 54 together define a second channel 56 for the first rail 22 to move in the second channel 56.
As shown in fig. 6 and 7, the embodiment of the present invention further includes a reinforcing member 58. In a preferred embodiment, the reinforcement 58 includes a plurality of reinforcement segments 60, the present invention being achieved by fixedly mounting the plurality of reinforcement segments 60 on the inner side 48a of the second sidewall 46 of the second rail 24; alternatively, the plurality of reinforcing sections 60 may be integrated into a reinforcing member 58 fixedly mounted to the inner side 48a of the second side wall 46 of the second rail 24. Preferably, the stiffener 58 has a first length L1, the second rail 24 has a second length L2, and the first length L1 is substantially equal to or slightly less than the second length L2, thereby enabling nearly full-length stiffening to increase the rigidity of the second rail 24.

As shown in fig.8, the slide rail assembly 10 of the present invention enhances the bending strength of the second rail 24 by the reinforcing member 58. Preferably, the cross section of the reinforcing member 58 has a first thickness X1, the cross section of the second rail 24 has a second thickness X2, and the first thickness X1 is smaller than the second thickness X2, so that the second rail 24 does not increase in width outward, thereby having the effect of narrowing the slide rail assembly 10 and being capable of carrying a chassis with a wider width. Fig.8 further shows that the upper supporting bar 29 is disposed inside the first upper wall 28 of the first rail 22 for supporting the second upper wall 42 of the second rail 24. The lower support bar 31 is disposed inside the first lower wall 30 of the first rail 22 for supporting the second lower wall 44 of the second rail 24.
As shown in fig. 9 to 11, the second rail 24 is movably displaceable along a longitudinal direction D relative to the first rail 22. When the second rail 24 is displaced from a first position P1 to a second position P2 relative to the first rail 22, the first latching feature 36 and the second latching feature 64 can be latched and positioned. In detail, in this process, the end of the elastic sheet 62 of the reinforcing member 58 will pass over the inclined portion 38 of the first latching feature 36 of the first rail 22 until the second latching feature 64 of the elastic sheet 62 of the reinforcing member 58 is displaced to correspond to the first latching feature 36 of the first rail 22, and the first latching feature 36 and the second latching feature 64 can be latched by the elastic force of the elastic sheet 62 of the reinforcing member 58, so that the second rail 24 is kept in such a latching and positioning state relative to the first rail 22 by the blocking portion 40 of the first latching feature 36.
As shown in fig. 12, when a force F is applied to the elastic sheet 62 of the reinforcing member 58, the second latching feature 64 of the elastic sheet 62 can be disengaged from the first latching feature 36 of the first rail 22, and the latching state therebetween is released, so that the second rail 24 can be pushed into and retracted relative to the first rail 22.
As described above, by the above design of the structural reinforcement and the functionality of the second rail 24, and referring to fig.1, the holes 66 and 68 on the second rail 24 and the corresponding holes 70 and 72 on the reinforcement 58 are used for mounting the plurality of mounting members 18 of the chassis 12, when the chassis is mounted, an installer can first clip the mounting member 18 at the rear end of the chassis 12 into the J-shaped hole 68 of the second rail 24 and the J-shaped corresponding hole 72 of the reinforcement 58, and then use the gravity of the chassis 12 to clip the remaining mounting members 18 on the chassis 12 into the U-shaped hole 66 of the second rail 24 and the U-shaped corresponding hole 70 of the reinforcement 58, so as to mount the chassis 12 on the second rail 24, and the slide rail assembly 10 can provide the chassis 12 with a stable support.
From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are: the strength of the rail piece is increased and the structure of the sliding rail assembly is narrowed.
Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
