[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] A slide rail damper, including

[0027] The fixing plate 1 includes a main body 11, guide parts 12 disposed on both sides of the main body 11 and inserted into the slide rail body, and mounting grooves 13 disposed on the guide parts 12.

[0028] The movable plate 2 is slidably engaged with the fixed plate 1;

[0029] The damper 3 includes a body 31 and a piston end 32 that slides in cooperation with the body 31. The body 31 is disposed on the mounting groove 13 and the piston end 32 is mounted on the movable plate 2.

[0030] The guide portion 12 is provided with a pre-tightening member 4, which protrudes from the guide portion 12. When the guide portion 12 is inserted into the slide rail body, the pre-tightening member 4 is pressed by the slide rail body and elastically deforms towards the guide portion 12.

[0031] This utility model provides a slide rail buffer. Through the pre-tightening member on the guide part, the pre-tightening member can keep pressing against the slide rail body when the fixing plate and the slide rail body are inserted and assembled, which increases the adaptability and ensures that the slide rail buffer can be stably and firmly installed on the slide rail, avoiding loosening.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the mounting groove 13 is provided with a through hole 14, and the preload 4 is located in the through hole 14. The through hole 14 provides a space 15 for the elastic deformation of the preload 4. When the preload is compressed, it will be recessed in the direction of the through hole, thereby maintaining the effect of pressing against the slide rail body, which can both avoid excessive pressure and avoid damage to the preload.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the top of the guide portion 12 is provided with a limiting platform 16 protruding near the inner side and a sliding platform 17 recessed near the outer side, and the preload 4 protrudes from the sliding platform 17. When assembled with the slide rail, the limiting platform plays a guiding and limiting role on the edge of the slide rail body, i.e., the edge of the slot.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the through hole 14 penetrates both the limiting platform 16 and the sliding platform 17, and the preload 4 spans both the limiting platform 16 and the sliding platform 17. After assembly with the slide rail, the preload protrudes from the limiting platform through the through hole, facilitating observation and the use of tools to press down the preload for easy disassembly.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the pretensioner 4 is provided with a first inclined surface 41 that gradually rises along the insertion direction of the slide rail body. This facilitates pressing the pretensioner.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding platform 17 is provided with a second inclined surface 18 that gradually rises along the insertion direction of the slide rail body. This facilitates guiding the insertion of the slide rail body.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, one mounting groove 13 is provided with the damper 3, and the other mounting groove 13 is provided with the spring 6. Currently, commercially available slide rail buffers generally use two dampers; using one damper can reduce costs.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, one end of the mounting groove 13 is provided with a positioning protrusion 131 corresponding to the bottom of the damper 3, and the other end is provided with a clamping rib 132 for pressing against the top of the damper 3. This facilitates pressing the damper into the mounting groove.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the bottom of the mounting groove 13 and the movable plate 2 are respectively provided with a latch 133. The spring 6 includes a telescopic part 61, narrowing parts 62 located at both ends of the telescopic part 61, and a limiting part 63 located at the end of the narrowing part 62. The latch 133 allows the narrowing part 62 to be engaged, facilitating the installation of the spring.

[0040] The slide rail includes a slide rail body 7, a slot 71 disposed on the slide rail body 7, and a slide rail buffer as described above inserted into the slot 71.

[0041] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
