Description

Technical Field

[0001] This utility model relates to a quick-installation device for drawer slides, specifically a quick-installation device for drawer slides that can be finely adjusted in multiple directions. Background Technology

[0002] Drawer slides typically consist of inner and outer rails, connected by ball bearings. The inner rails are mounted on the side walls of the drawer, while the outer rails are mounted on the two inner walls of the cabinet. The inner and outer rails cannot be disassembled, preventing the drawer from separating from the cabinet frame. This necessitates completely emptying the drawer before moving or transporting the furniture. To address this issue, quick-release mechanisms are installed at the bottom of the drawer for rapid connection to the cabinet frame. These mechanisms utilize interlocking brackets that connect to the cabinet frame's locking plates, allowing for quick drawer separation. However, these quick-release mechanisms require high installation precision. Even slight deviations during installation can lead to misalignment between the outer and inner rails, preventing the drawer from installing properly and causing it to slid awkwardly or become stuck. Furthermore, the current quick-release mechanism installation method is relatively fixed and lacks a flexible adjustment mechanism. Any deviation during installation can result in uneven gaps between the drawer and the cabinet frame. Especially after drilling holes to install quick-release devices, any deviation in position requires readjusting the drilling and installation, which can easily damage the integrity of the drawer or cabinet, resulting in higher rework costs. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a drawer slide quick-installer with a simple structure, low manufacturing cost, multi-directional micro-adjustment, drawer achieving ideal installation state, stable and firm connection, easy and quick operation, and improved overall aesthetics.

[0006] The longitudinal adjustment device includes a longitudinal threaded groove recessed in the base, and a longitudinal threaded rod connected in the longitudinal threaded groove. Rotating the longitudinal threaded rod drives the base to slide back and forth along the longitudinal threaded groove, thereby realizing the adjustment of the longitudinal gap between the drawer and the guide rail.

[0007] The axial adjustment device includes an axial adjustment groove recessed in the base and an axial adjustment plate built into it. An axial adjustment nut is connected to an axial threaded rod provided at the tail of the axial adjustment plate. Rotating the axial adjustment nut drives the axial adjustment plate to move up and down, thereby realizing the adjustment of the axial gap between the drawer and the guide rail.

[0008] The top of the transverse threaded rod is equipped with a transverse adjusting nut, and a transverse slot is opened through the end face of the base. The transverse adjusting nut is fixed in the transverse slot.

[0009] The side end of the horizontal adjustment plate is inclined inward to form a horizontal boss, which protrudes from the base and presses against the guide rail.

[0010] The longitudinal threaded rod is equipped with a longitudinal adjusting nut at the top and a longitudinal slot is provided through the end face of the base. The longitudinal adjusting nut is fixed in the longitudinal slot.
