[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A self-locking mechanism for a furniture slide rail includes a positioning buffer member, a fixed rail, and a movable rail. A mounting block is fixedly connected to the top of the movable rail. A plurality of positioning grooves with equal groove diameters are formed on one side of the mounting block. A positioning block with an arc-shaped side is snap-fitted inside the positioning groove. Chute grooves are formed at the top and bottom of the positioning block. A first spring is arranged inside the chute groove. A block with an arc-shaped side is slidably connected inside the chute groove. A card slot communicating with the positioning groove is formed inside the mounting block. The block is snap-fitted inside the card slot. A slider is fixedly connected to the bottom of the positioning block away from the block. A connecting shaft rod is slidably connected inside the slider. A second spring is sleeved outside the connecting shaft rod.

[0007] Preferably, fixing blocks are fixedly connected to both ends of the connecting shaft rod. The fixing blocks are fixedly connected to the end face of the movable rail. The fixing blocks are symmetrically arranged.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] A self-locking mechanism for a furniture slide rail, comprising a positioning buffer member 1, a fixed rail 2 and a movable rail 3. A mounting block 4 is fixedly connected to the top of the movable rail 3. A plurality of positioning grooves 5 with equal groove diameters are formed on one side of the mounting block 4. A positioning block 6 with an arc-shaped side is snap-fitted inside the positioning groove 5. Chute grooves 7 are formed at the top and bottom of the positioning block 6. A first spring 8 is arranged inside the chute groove 7. A clamping block 9 with an arc-shaped side is slidably connected inside the chute groove 7. A clamping groove 10 communicating with the positioning groove 5 is formed inside the mounting block 4. The clamping block 9 is snap-fitted inside the clamping groove 10. A slider 11 is fixedly connected to the bottom of the positioning block 6 away from the clamping block 9. A connecting shaft rod 12 is slidably connected inside the slider 11. A second spring 13 is sleeved outside the connecting shaft rod 12.

[0027] Both ends of the connecting shaft rod 12 are fixedly connected with fixing blocks 16. The fixing blocks 16 are fixedly connected with the end faces of the movable tracks 3. The fixing blocks 16 are symmetrically arranged. This arrangement enables the positioning of the connecting shaft rod 12 through the fixing blocks 16. The sliders 11 are symmetrically arranged. The second spring 13 is arranged between a group of sliders 11. Both ends of the second spring 13 are fixedly connected with the sliders 11. This arrangement enables the sliders 11 to act on the second spring 13 when they slide relatively, and the reaction elastic force generated by the second spring 13 enables the sliders 11 to drive the positioning blocks 6 to closely fit with the positioning grooves 5. The bottom of the slider 11 is fixedly connected with a limiting block 14. A limiting groove 15 is formed at the top of the movable track 3. The limiting block 14 is arranged inside the limiting groove 15 and is slidably connected with the limiting groove 15. This arrangement enables the slider 11 to drive the limiting block 14 to slide relatively in the limiting groove 15 when the slider 11 moves, enabling the slider 11 to slide stably. Both ends of the first spring 8 are respectively fixedly connected with the inner wall of the chute 7 and the clamping block 9. The clamping blocks 9 are symmetrically arranged. This arrangement enables the clamping blocks 9 to be first acted on by the mounting block 4. The clamping blocks 9 slide inside the chute 7 and act on the first spring 8, causing the first spring 8 to be compressed. The first spring 8 generates a reaction elastic force, and the elastic force of the first spring 8 enables the clamping blocks 9 to be more stably clamped inside the clamping grooves 10.

[0028] Working process: When pulling the furniture component connected to the movable track 3, the furniture component drives the movable track 3 to slide relatively with the fixed track 2 at its bottom. The movable track 3 drives the limiting block 14, the slider 11, the positioning block 6, etc. to move. When the movable track 3 slides to a certain position, adjust the position of the movable track 3 back and forth so that the arc-shaped end of the positioning block 6 is clamped in the positioning groove 5. In this process, the positioning block 6 first slides out of a certain positioning groove 5, and the positioning block 6 acts on the slider 11, causing the slider 11 to slide relatively with the connecting shaft rod 12. The connecting shaft rod 12 is installed on the top of the movable track 3 through the fixing block 16. The slider 11 drives the limiting block 14 to slide relatively in the limiting groove 15, and the second spring 13 is compressed by the slider 11. When the positioning block 6 is clamped in the positioning groove 5, the clamping block 9 is also clamped inside the clamping groove 10 at the same time. In this process, the clamping block 9 is first acted on by the mounting block 4. The clamping block 9 slides inside the chute 7 and acts on the first spring 8, causing the first spring 8 to be compressed. The first spring 8 generates a reaction elastic force, and the elastic force of the first spring 8 enables the clamping block 9 to be more stably clamped inside the clamping groove 10, thereby realizing the self-locking of the furniture slide rail. The positioning buffer 1 is fixed on one side of the fixed track 2, and the positioning buffer 1 can protect the movable track 3 when it is reset.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
