Description

Technical Field

[0001] This utility model relates to the field of slide rail and slider technology, and in particular to a slide rail and slider with a shock-absorbing auxiliary wheel. Background Technology

[0002] Currently, many automated devices use a slide rail slider structure. However, this type of slide rail structure is simple and has a single function, only providing displacement. Under long-term use, the slider is prone to displacement from the slide rail, resulting in collisions and significant vibrations, which makes the equipment unstable. Therefore, it is necessary to propose a slide rail slider with shock-absorbing auxiliary wheels.

[0003] Therefore, the utility model patent with application number CN202220414447.3 proposes a slide rail slider with shock-absorbing auxiliary wheel, including a slide rail body, a trapezoidal slide cavity is provided in the slide rail body, and a slider is movably assembled in the trapezoidal slide cavity... It will not cause large positional displacement, and avoids collision between the slider and the trapezoidal slide cavity, which would damage the slide rail body or cause deformation, thereby improving the service life of the slide rail slider;

[0004] Despite the numerous advantages demonstrated by the comparative document, such as the use of springs to achieve a buffering and anti-collision effect to ensure stable sliding of the slider, the closed design of the springs makes disassembly and assembly difficult during maintenance, repair, or replacement. Its convenience and operational efficiency still need further improvement and optimization. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A slide rail slider with shock-absorbing auxiliary wheel includes a slide rail body 1. The slide rail body 1 is provided with a trapezoidal slide cavity. A slider 2 is movably assembled in the trapezoidal slide cavity, as disclosed in the prior art, and will not be repeated here. The inner sides and the inner top of the slide cavity are provided with openings. A connecting block 3 is slidably connected to the inner side wall of the opening for supporting the roller 4. Both sides of the connecting block 3 are provided with arc-shaped grooves. A ball is rolledly connected to the inner side wall of the arc-shaped groove to reduce the resistance when the connecting block 3 moves. Part of the ball passes through the arc-shaped groove.

[0021] In this embodiment, the end of the connecting block 3 facing the slider 2 passes through the opening and extends into the sliding cavity. The end of the connecting block 3 facing the slider 2 is provided with a connecting groove. A roller 4 is rolled on the inner side wall of the connecting groove to reduce the resistance when the slider 2 slides. The two ends of the roller 4 are rotatably connected to the inner sides of the connecting groove respectively. The outer side wall of the slider 2 is provided with a groove corresponding to the roller 4. The groove is arranged longitudinally. The end of the roller 4 away from the connecting block 3 passes through the connecting groove and extends into the groove.

[0022] In this embodiment, four rectangular guide rods 5 are slidably inserted at the other end of the connecting block 3 to guide the movement of the connecting block 3. A support block 12 is slidably inserted at the end of the opening away from the connecting block 3 to support the spring 6. The end of the guide rod 5 away from the connecting block 3 is fixedly connected to the support block 12. The spring 6 is slidably sleeved on the guide rod 5 to buffer and dampen shock. The two ends of the spring 6 abut against the connecting block 3 and the support block 12 respectively. The end of the support block 12 away from the connecting block 3 is provided with a receiving groove. A first pull ring 10 is fixedly connected to the inner wall of the receiving groove to facilitate the user to manually pull the support block 12 outward.

[0023] In this embodiment, a cover plate 11 corresponding to the opening is rotatably connected to the outer wall of the slide rail body 1 to prevent the support block 12 from disengaging from the opening. A locking screw 7 is provided at the end of the cover plate 11 away from the slide rail body 1 to fix the cover plate 11. The cover plate 11 is fixed to the slide rail body 1 by the locking screw 7. A knob 8 is fixedly connected at the end of the locking screw 7 away from the cover plate 11 to facilitate manual rotation of the locking screw 7 by the user. A rubber block is fixedly connected to the side of the cover plate 11 close to the slide rail body 1 to prevent wear between the support block 12 and the cover plate 11. One end of the rubber block slides into the opening and abuts against the support block 12. A second pull ring 9 is fixedly connected to the side of the cover plate 11 away from the slide rail body 1 to facilitate the user to grip and unscrew the cover plate 11.

[0024] In this embodiment, when the slider 2 is displaced in the up, down, left, or right directions, it will push the roller 4. The roller 4 will drive the connecting block 3 to slide inside the passage, thereby compressing the spring 6 and realizing the buffering and shock absorption function. If the spring 6 needs maintenance, repair, or replacement, the operation steps are as follows: First, manually rotate the knob 8 to drive the locking screw 7 to rotate and loosen it. Then, unscrew the cover plate 11. At this time, the support block 12 can be manually pulled out from inside the passage. This action will also drive the guide rod 5 to be taken out together (or, the elasticity of the spring 6 can also help the support block 12 and the guide rod 5 to separate from inside the passage). Once the guide rod 5 is taken out, the necessary maintenance, repair, or replacement of the spring 6 can be easily performed.

[0025] As described above, the slide rail body and slider have been disclosed in the prior art or are existing mature technologies. Their working principle and internal structure are known to those skilled in the art. This application only utilizes their function and does not improve their internal structure. Therefore, it will not be described in detail.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
