[0028] Embodiment 1:

[0029] Refer to Figures 1 - 10 , the double-functional buffer and rebound device for the slide rail includes an outer rail 1, a middle rail 2, and an inner rail 3 that are sequentially slidably connected.

[0031] The lower guide rail 405 is arranged in a "丿" shape.

[0032] The limit hook assembly includes a sliding hook 8 rotatably connected to the large slider 5, an upper guide rail 403 is provided on the main body 4, a separation opening 404 is provided at the end of the upper guide rail 403 away from the inner rail 3, and the separation opening 404 is inclined. A lower protrusion 801 is provided at the end of the sliding hook 8 close to the main body 4, and the lower protrusion 801 is slidably connected in the separation opening 404.

[0033] The large slider 5 is provided with a rotating groove 504, the end of the sliding hook 8 away from the lower protrusion 801 is provided with an upper protrusion 802, the upper protrusion 802 is rotatably connected in the rotating groove 504, the large slider 5 is provided with an extrusion guide groove 503, the push block 6 is provided with an extrusion block 601, and the extrusion block 601 is slidably connected to the extrusion guide groove 503.

[0034] A compression spring column 501 is symmetrically arranged at one end of the large slider 5 close to the small slider 7 , and the counter-pressure spring 402 is sleeved on the compression spring column 501 .

[0035] A buffer damper 401 is fixedly connected to the main body 4, and the other end of the buffer damper 401 is connected to the large slider 5, which can provide buffering during the closing process.

[0036] An elastic sheet is arranged at one end of the small slider 7 close to the middle rail 2, which has a certain buffering effect.

[0037] In the open state, refer to Figures 1 - 3 , the buffer damper 401 is in an extended state, the large slider 5 slides to the middle part of the main body 4 under the elastic force of the back pressure spring 402, the push block 6 is located near the middle part of the large slider 5 under the tension of the small tension spring 602, the large slider 5 and the small slider 7 are affected by the tension of the buffer spring 502, the large slider 5 and the small slider 7 are attached to each other, at this time the inner rail 3 is in an open state, the separation piece 702 on the inner rail 3 is separated from the driven shaft 701, the driven shaft 701 is located at one end of the "丿" type lower guide rail 405 close to the inner rail 3, and the sliding hook 8 is located on the side of the upper guide rail 403 close to the inner rail 3;

[0038] When the slide rail needs to be closed, the inner rail 3 is pushed to slide, and the inner rail 3 first contacts the push block 6. At this time, the inner rail 3 is continued to be pushed. Since the extrusion block 601 on the push block 6 is blocked by the upper protrusion 802 at this time, the inner rail 3 pushes the large slider 5 to slide synchronously through the push block 6, the extrusion block 601, the upper protrusion 802, and the sliding hook 8, so that the back pressure spring 402 is gradually compressed;

[0039] It should be noted that, during the closing process, that is, when the lower protrusion 801 has not slid to the separation opening 404, the upper protrusion 802 is blocked by the side wall of the upper guide rail 403 of the main body 1 and cannot rotate;

[0040] When the lower protrusion 801 slides to the separation opening 404, the lower protrusion 801 is squeezed by the squeezing block 601 and stuck in the separation opening 404, and the back pressure spring 402 is compressed. At this time, the squeezing block 601 can slide in the squeezing guide groove 503, so that the push block 6 is in contact with the end of the large slider 5. In the process of the push block 6 sliding along the squeezing guide groove 503, the separation and combination piece 702 will gradually be in contact with the driven shaft 701. Affected by the "丿" type limiting groove 703, the driven shaft 701 will rotate around the rotation point of the rotating piece 705 in the arc groove 704. At this time, the driven shaft 701 will be stuck in the limiting groove 703 near the middle part of the separation and combination piece 702, completing the contact limit of the small slider 7 and the inner rail 3.

[0041] It should be noted that, since the large slider 5 has been limited by the sliding hook 8 at this time, the small slider 7 is fixed and limited by the pulling force of the buffer spring 502 and the small tension spring 602, thereby completing the limit fixation of the inner rail 3 and entering the closed state. In the process of closing the inner rail 3, the small tension spring 602 can be used to buffer when placing heavy objects in the drawer or closing it violently, thereby preventing damage to the drawer;

[0042] When it is necessary to enter the open state from the closed state, the inner rail 3 is first pushed to slide inward, and the inner rail 3 pushes the large slide block 5 to slide inward through the push block 6, so that the sliding hook 8 and the lower protrusion on the large slide block 5 slide along the arc of the separation opening 404, so that the lower protrusion 801 leaves the separation opening 404, and the large slide block 5 is not limited at this time. Under the action of the small tension spring 602 and the back pressure spring 402, the large slide block 5, the sliding hook 8, the push block 6, and the inner rail 3 slide in the opposite direction and open quickly. At this time, the buffer spring 502 can buffer the tension of the small tension spring 602 during the opening process to prevent the drawer from being damaged;

[0043] It should be noted that when the push block 6 passes through the rotating groove 504, an elastic hollow groove is provided at one end of the upper guide rail 403 close to the rotating groove 504, so that the squeezing block 601 can squeeze the upper protrusion 802 and the sliding hook 8 rotates, so that the push block 6 passes over the sliding hook 8 to the open state.

[0044] The utility model can quickly open the drawer without setting a handle through the arranged small tension spring 602, large slider 5, sliding hook 8 and separating and combining piece 702, and has a buffering effect when closing, can protect the drawer when opening and closing the drawer, and improves the service life of the slide rail and the drawer.

[0045] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacement or change, and should be covered within the protection scope of the utility model.
