[0002] In the design of existing furniture and mechanical equipment, as a key component to realize the smooth movement of drawers or sliding parts, the performance and structural design of the two-section small full-extension guide rail are directly related to the user experience and the overall life of the equipment. In traditional two-section small full-extension guide rails, the design of the buffer assembly structure mostly adopts directly clamping the buffer assembly on the tearing claws after processing the tearing claws on the guide rail. The assembly method is laborious, and when the buffer assembly is damaged, it is not convenient to disassemble and replace, which is not conducive to the maintenance of product replacement parts. Content of the Utility Model

The elastic structure includes a swing arm with one end connected to the buffer frame and a snap part arranged on the outer side of the free end of the swing arm. An avoidance groove is arranged on the inner side of the buffer frame at the free end of the swing arm. When the buffer frame is in relative contact with the first guide rail and the clamping hook is clamped into the clamping-in part of the clamping groove and slides in place along the clamping part, the snap part is clamped into the positioning groove from the outside to realize the connection between the buffer frame and the first guide rail.

When the first guide rail and the buffer frame are assembled, the clamping hook is clamped into the clamping-in part of the clamping groove and slides in place along the clamping part, so that the snap part can be clamped into the positioning groove from the outside to realize the connection between the buffer frame and the first guide rail. And when the snap part is pressed to disengage from the positioning groove, the disassembly of the buffer frame and the first guide rail is realized. The installation and disassembly method of the buffer assembly is simple, which is convenient for replacing the buffer assembly and maintaining the guide rail device.

[0007] Further, the width of the insertion part is greater than that of the clamping part, the width of the clamping part is adapted to the width of the hook, and the clamping part in the card slot and the buckle part of the elastic structure are respectively arranged on the adjacent or relatively far - away sides; By such a setting, it is easier for the hook to be inserted into the card slot, and the assembly of the buffer frame and the first guide rail is more convenient.

[0010] Further, the hook also includes a clamping block and a positioning stop part, the clamping block and the positioning stop part are integrally in an L - shape, and the clamping part is correspondingly in an L - shape; By such a setting, the hook has better structural strength and provides the reliability of product assembly connection.

[0011] Further, the limiting block is respectively connected to the outer ends of the clamping block and the positioning stop part; By such a setting, the overall structure of the hook is more stable and has higher structural strength.

[0012] Further, there are multiple card slots, the number of hooks corresponds to the number, and the positioning slot is located between two adjacent card slots; By such a setting, the assembly connection between the buffer frame and the first guide rail is more stable.
