Technical Field

[0001] This utility model relates to slide rails, and more particularly to a slide rail. Background Technology

[0002] In many applications requiring linear or specific trajectory unfolding / retracting movements (such as folding furniture, telescopic sunshade systems, telescopic arms of industrial equipment, drawer slides, etc.), the guide rail system is the core component for achieving this function. Currently, commonly used guide rail technologies mainly rely on sliding friction pairs (such as sliders and grooves) or rolling friction pairs (such as ball / roller guides) to achieve relative movement. However, existing guide rail technologies often face problems such as uneven unfolding and instability after unfolding, thus requiring improvement. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies, such as unsmooth unfolding and insufficient stability after unfolding, by providing a new type of slide rail.

[0006] This application uses a fixed rail to cooperate with the first and second sliding rails. On the one hand, it can improve the smoothness of the first and second sliding rails when they are unfolded. On the other hand, the fixed rail can also provide some support for the first and second sliding rails, thereby improving the stability of the sliding rails after they are unfolded.

[0007] Preferably, in the slide rail described above, the fixed rail includes a fixed part and a sliding part, the first slide rail is slidably connected to the sliding part, the upper end of the sliding part is provided with a stop groove, and the first slide rail is provided with a locking post, the locking post cooperating with the stop groove.

[0008] Preferably, in the slide rail described above, the first slide rail is provided with a locking groove, and the locking pin can move up and down within the locking groove.

[0009] Preferably, in the slide rail described above, the sliding part is further provided with a first sliding groove, and the first slide rail is provided with a first sliding post, and the first slide rail slides in cooperation with the first sliding groove through the first sliding post.

[0010] Preferably, in the slide rail described above, the sliding part is further provided with a first sliding wheel, and the lower end of the first slide rail cooperates with the first sliding wheel.

[0011] Preferably, in the slide rail described above, the first slide rail has a second sliding groove, the second slide rail has a second sliding post, and the second slide rail slides in cooperation with the second sliding groove through the second sliding post.

[0012] Preferably, in the slide rail described above, the fixing part protrudes upward to form a guide rail, and the lower end of the second slide rail is provided with a guide groove that cooperates with the guide rail.

[0013] Preferably, in the slide rail described above, the first slide rail is further provided with a second slide wheel, and the upper end of the second slide rail cooperates with the second slide wheel.

[0014] The present invention has the following advantages through the above structural improvements:

[0015] Compared with conventional slide rails, this application has the advantages of smooth deployment and greater stability after deployment. Specifically, the first and second slide rails are deployed by cooperating with corresponding sliding columns and grooves, which can effectively improve the smoothness of the guide rail during deployment. Furthermore, after deployment, the sliding part, the first sliding wheel, and the second sliding wheel can also support the first and second slide rails, thus effectively improving the stability of the guide rail during deployment.

[0020] The following is in conjunction with the appendix Figure 1-3The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a slide rail includes a slide rail body 1. The slide rail body 1 includes a fixed rail 11, a first slide rail 12, and a second slide rail 13. The first slide rail 12 is mounted on the fixed rail 11 and can slide on the fixed rail 11. The second slide rail 13 is mounted on the first slide rail 12 and can slide on the first slide rail 12.

[0022] Preferably, the fixed rail 11 includes a fixed part 111 and a sliding part 112. The first sliding rail 12 is slidably connected to the sliding part 112. The upper end of the sliding part 112 is provided with a stop groove 1121. The first sliding rail 12 is provided with a locking pin 121, and the locking pin 121 cooperates with the stop groove 1121.

[0023] Specifically, when the first sliding rail 12 is extended, the locking pin 121 and the stop groove 1121 of the sliding part 112 cooperate with each other. When the first sliding rail 12 is retracted, the locking pin 121 and the stop groove 1121 of the sliding part 112 disengage. The fixing part 111 and the sliding part 112 are integrally formed.

[0024] Preferably, the first sliding rail 12 is provided with a locking groove 122, and the locking pin 121 can move up and down within the locking groove 122.

[0025] In this embodiment, the stop groove 1121 has an inclined slope. When the first sliding rail 12 is not unfolded, the locking pin 121 is located at the upper part of the locking groove 122. When the first sliding rail 12 is unfolded, the locking pin 121 will move downward synchronously with the inclined slope, so that when unfolded, the locking pin 121 is located at the lower part of the locking groove 122.

[0026] Preferably, the sliding part 112 is further provided with a first sliding groove 1122, and the first sliding rail 12 is provided with a first sliding post 124. The first sliding rail 12 slides in cooperation with the first sliding groove 1122 through the first sliding post 124.

[0027] More specifically, the first sliding rail 12 cooperates with the first sliding groove 1122 via the first sliding post 124. This allows the first sliding rail 12 to be installed with the sliding part 112, and also improves the smoothness of the first sliding rail 12 when it is extended or retracted.

[0028] Preferably, the sliding part 112 is further provided with a first sliding wheel 1123, and the lower end of the first sliding rail 12 cooperates with the first sliding wheel 1123.

[0029] Specifically, the first sliding rail 12 can further improve the smoothness of the first sliding rail 12 when it is extended or retracted by cooperating with the first sliding wheel 1123, and the first sliding wheel 1123 can also support the first sliding rail 12 after it is extended.

[0030] Preferably, the first sliding rail 12 is provided with a second sliding groove 123, and the second sliding rail 13 is provided with a second sliding post 131. The second sliding rail 13 slides in cooperation with the second sliding groove 123 through the second sliding post 131.

[0031] Specifically, the second sliding rail 13 cooperates with the second sliding groove 123 through the second sliding column 131, which on the one hand allows the second sliding rail 13 to be installed with the first sliding rail 12, and on the other hand can improve the smoothness of the second sliding rail 13 when it is extended or retracted.

[0032] Preferably, the fixing part 111 protrudes upward to form a guide rail 1111, and the lower end of the second sliding rail 13 is provided with a guide groove 132 that cooperates with the guide rail 1111.

[0033] More specifically, the cooperation between the guide rail 1111 and the guide groove 132 can guide the second sliding rail 13 to prevent displacement when the second sliding rail 13 is extended or retracted, and can also improve the smoothness of the second sliding rail 13 when it is extended or retracted.

[0034] Preferably, the first sliding rail 12 is further provided with a second sliding wheel 125, and the upper end of the second sliding rail 13 cooperates with the second sliding wheel 125.

[0035] More specifically, with the assistance of the second sliding wheel 125, the smoothness of the second sliding rail 13 when it is extended or retracted can be further improved.

[0036] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
