[0001] The present invention relates to the field of drawer slide rails, and in particular to a connection structure for two-section slide rails and an installation method thereof. Background Art

[0002] At present, drawers are one of the important components of furniture, and drawer slides are frequently used accessories in furniture. The existing drawer slide connection structure includes a drawer side panel with a panel adjustment device provided inside. The front and rear sides of the bottom of the panel adjustment device are respectively provided with a hook to prevent the movable rail from moving forward and a lock tongue to prevent the movable rail from moving backward. The hook and the lock tongue extend out of the bottom of the drawer side panel and are connected to the movable rail. The front end of the top of the movable rail is inserted into the hook, and the front end face of the movable rail is blocked by the inner end face of the hook. A backstop hole is provided behind the front end face of the movable rail corresponding to the lock tongue. Under normal circumstances, when the front end of the movable rail is inserted into the hook, when the front end face of the movable rail contacts the inner end face of the hook, the backstop hole of the movable rail is aligned with the lock tongue, and the lock tongue slides into the backstop hole, thereby realizing the connection between the drawer side panel and the slide rail. However, due to factors such as machining accuracy and ambient temperature, it is generally not possible to ensure that the distance between the front end of the lock tongue and the inner end of the retaining hook is equal to the distance between the front end of the retaining hole and the front end of the movable rail. Furthermore, if the distance between the front end of the retaining hole and the front end of the movable rail is greater than the distance between the front end of the lock tongue and the inner end of the retaining hook, the drawer side panel and the slide rail will not be connected. Therefore, the existing structure is complex, inconvenient to assemble when matching and adjusting with the slide rail, and the cost is too high, which is not conducive to popularization.

[0010] A first method for installing the connecting structure for the two-section slide rails as described above is to pull out the two movable rails, lock the drawer from top to bottom, and make the elastic clamping piece lock into the head glue to complete the installation.

[0011] A second installation method for the connecting structure for the two-section slide rail as described above is to directly place the drawer on the movable rail and push it into the drawer cabinet so that the elastic clip is engaged with the head glue to complete the installation.

[0012] The present invention utilizes metal elasticity to connect the elastic clip to the head glue. When the drawer and slide rail are assembled, the elastic clip encounters the wider front end of the head glue (the engaging portion), causing the elastic clip to be stretched open by the head glue. After passing through the wide portion, the elastic clip engages the recessed portion of the head glue, completing the connection. The end of the spring piece is provided with a curved portion, which acts as a guide and locking mechanism, facilitating assembly of the elastic piece and the head glue, and preventing damage to the head glue from collision during assembly.

[0013] The present invention has the following advantages: The elastic clamp is connected to the head rubber by metal elasticity, the head rubber is connected to the movable rail, and the elastic clamp is connected to the drawer. The mutually matching and snap-fitting connection enables quick installation and removal, simple structure, and low cost. The vertical adjustment portion can realize the vertical position adjustment of the drawer during installation, which is simple and convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS
