[0002] Drawer slides are commonly used accessories in furniture, used to enable drawers to open and close smoothly. When purchasing drawer slides, factors such as the required length, applicable scenarios, and the geometry that needs to bear the load should be considered. When the existing drawers are closed, the drawer slides are not provided with deceleration drawer slides. If too much force is applied, the drawer will violently hit the cabinet body, causing a loud impact sound or damaging the furniture. Therefore, it is necessary to design a buffer structure for the drawer slides. Summary of the invention

[0005] The working principle of the utility model is as follows: when the drawer is pushed back, the inner fixed rail and the bridging rail both slide, the end of the inner fixed rail hits the moving block, and pushes the moving block to slide into the mounting shell, so that the spring is compressed to buffer the slide rail, and at the same time, the auxiliary part is driven to move through the L-shaped connecting rod to assist in buffering and damping the slide rail, so that it is stably buffered until the inner fixed rail hits the outside of the shell of the mounting shell, and the drawer is closed. The utility model has a simple structure and is easy to use, and prevents the drawer from being pushed back without a deceleration rail to cause an impact sound or damage to the cabinet body.
[0006] The auxiliary component includes a shock-absorbing compression rod, a second spring and a fixed block. The shock-absorbing compression rod is fixedly connected to the mounting plate. The telescopic rod of the shock-absorbing compression rod is horizontally arranged. The second spring is sleeved on the telescopic rod of the shock-absorbing compression rod. The fixed block is connected to the end of the telescopic rod of the shock-absorbing compression rod, and the fixed block is connected to the moving block through an L-shaped connecting rod.
[0007] With the above structure, the damping compression rod, the second spring and the fixed block are arranged to assist the slide rail body in buffering and damping, so that the slide rail body can slide more stably.
[0008] A buffer pad is connected to one side of the installation shell where a shell opening is opened.
[0009] With the above structure, when the inner fixed rail slides bufferingly until it hits the shell of the mounting shell, the impact sound is avoided.
[0010] The moving block is made of a material with a smooth and soft surface.
[0011] The above structure can protect the inner fixed rail from being damaged when it collides with the moving block, and avoid the occurrence of impact sound.
[0012] The height of the slide is lower than the height of the inner fixed rail.
[0013] By adopting the above structure, the inner fixed rail can move smoothly without causing any obstruction.
[0014] Compared with the prior art, the buffer structure of the drawer slide rail has the following advantages:
[0015] By arranging a mounting shell, a slide, a moving block, a spring 1 and an auxiliary part at the end of the outer fixed rail of the slide rail body, the inner fixed rail moves when the drawer is pushed back, and double buffering is performed by the spring 1 and the auxiliary part. At the same time, the auxiliary part can also play a shock-absorbing role, making the slide rail buffering more stable, preventing the drawer from being pushed back without a deceleration rail to cause an impact sound or damage the cabinet body.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0022] like Figure 1-Figure 4 As shown, a buffer structure of a drawer slide rail comprises a slide rail body 1, and the slide rail body 1 comprises an outer fixed rail 10, an inner fixed rail 11 and a bridging rail 12, the tail end of the outer fixed rail 10 is connected to a mounting plate 2, a mounting shell 3 is arranged on the outer fixed rail 10, and the mounting shell 3 is connected to the mounting plate 2, a shell opening 4 is opened on the mounting shell 3, a slide 5 is arranged in the mounting shell 3 and passes through the shell opening 4, a moving block 6 is slidably connected to the slide 5, a spring 7 is fixedly connected to the mounting plate 2, one end of the spring 7 is connected to the mounting plate 2, and the other end of the spring 7 is connected to the moving block 6, auxiliary parts 8 are arranged on both sides of the spring 7, and the auxiliary parts 8 and the moving block 6 are connected by L-shaped connecting rods 9. In this embodiment, the connection method between the outer fixed rail 10, the inner fixed rail 11 and the bridging rail 12 adopts the existing technology.
[0023] The auxiliary component 8 includes a shock-absorbing compression rod 81, a second spring 82 and a fixed block 83. The shock-absorbing compression rod 81 is fixedly connected to the mounting plate 2. The telescopic rod of the shock-absorbing compression rod 81 is horizontally arranged. The second spring 82 is sleeved on the telescopic rod of the shock-absorbing compression rod 81. The fixed block 83 is connected to the end of the telescopic rod of the shock-absorbing compression rod 81, and the fixed block 83 is connected to the movable block 6 through the L-shaped connecting rod 9.
[0024] By adopting the above structure, through the arrangement of the shock-absorbing compression rod 81, the second spring 82 and the fixed block 83, the slide rail body 1 can be assisted in buffering and shock-absorbing, so that the sliding of the slide rail body 1 is more stable. In this embodiment, when the moving block 6 moves, it drives the fixed block 83 to move, and at the same time, the telescopic rod of the shock-absorbing compression rod 81 is extended and retracted, and cooperates with the second spring 82 to play a role in buffering and shock-absorbing the drawer slide rail.
[0025] A buffer pad 13 is connected to one side of the shell body on which the shell opening 4 is opened. With the above structure, when the inner fixed rail 11 slides with buffering until it hits the shell of the mounting shell 3, an impact sound is avoided. In this embodiment, the shape of the buffer pad 13 is matched with the shell opening 4 of the mounting shell 3.
