Description

Technical Field

[0001] This utility model relates to a quick-release mechanism for guide rails, specifically a multi-dimensional adjustable quick-release mechanism for guide rails. 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 inner walls of the cabinet frame. The inner and outer rails cannot be disassembled, meaning the drawer cannot be separated from the cabinet. When organizing or moving furniture, the drawer must be completely emptied before it can be moved. To address these drawbacks, quick-release mechanisms are installed at the bottom of the drawer for rapid connection to the cabinet frame. These mechanisms use interlocking brackets to connect with the cabinet's locking plates, allowing for quick drawer separation. However, these quick-release mechanisms require high installation precision. Even slight deviations during installation can cause the outer and inner rails to misalign, preventing the drawer from installing properly and resulting in the drawer not sliding smoothly or getting stuck. Furthermore, the installation method of existing quick-release mechanisms is relatively fixed and lacks a flexible adjustment mechanism. Any deviation during installation can directly lead to 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.

[0019] The present invention will be further described below with reference to the accompanying drawings. A multi-dimensional adjustable quick-release drawer slide includes a base 2 and a cover plate 1 covering its top. The cover plate 1 and the base 2 enclose a receiving cavity. A lateral adjustment device, a longitudinal adjustment device, and an axial adjustment device are respectively embedded in the receiving cavity for adjusting the lateral, longitudinal, and axial clearances between the drawer and the drawer slide.

[0020] The axial adjustment device includes an axial adjustment groove 41 formed by the recess of the base 2, and an axial adjustment plate 42 built into the axial adjustment groove 41. The axial adjustment groove 41 is provided with an axial fixing groove 44. An axial adjustment nut 46 is inserted into the axial fixing groove 44 and rotated, pressing against the end face of the axial adjustment plate 42. The axial adjustment device also includes an axial threaded rod 45 connected to one end of the axial adjustment plate 42. The axial adjustment nut 46 is fitted onto the axial threaded rod 45 and screwed to it. Rotating the axial adjustment nut 46 drives the axial adjustment plate 42 to slide along the axial adjustment groove 41, thereby realizing the adjustment of the axial gap between the drawer and the guide rail.

[0021] The axial fixing groove 44 passes through the base 2, and the axial adjusting nut 46, which is embedded in the axial fixing groove 44, protrudes from the end face of the axial adjusting plate 42.

[0022] The front end of the axial adjustment plate 42 extends upward and tilts to form an axial boss 43, which protrudes from the base 2 and presses against the guide rail.

[0023] The lateral adjustment device includes a lateral adjustment groove 31 formed by the recess of the base 2, and a lateral adjustment plate 32 built into the lateral adjustment groove 31; the lateral adjustment device also includes a lateral threaded rod 34, and the end face of the lateral adjustment plate 32 is recessed to form a lateral adjustment threaded groove 36. The lateral threaded rod 34 passes through the base 2 and is installed in the lateral adjustment threaded groove 36. Rotating the lateral threaded rod 34 drives the lateral adjustment plate 32 to slide left and right along the lateral adjustment groove 31, thereby realizing the adjustment of the lateral gap between the drawer and the guide rail.

[0024] A horizontal adjusting nut 35 is installed on the top of the horizontal threaded rod 34, and a horizontal slot 21 is provided through the side wall of the base 2. The horizontal adjusting nut 35 is fixed in the horizontal slot 21.

[0025] The side end of the horizontal adjustment plate 32 is inclined inward to form a horizontal boss 33, which protrudes from the base 2 and presses against the guide rail.

[0026] The longitudinal adjustment device includes a longitudinal adjustment groove 51 formed by the recess of the base 2, and a longitudinal adjustment plate 52 built into the longitudinal adjustment groove 51; the longitudinal adjustment device also includes a longitudinal threaded rod 54, and the end face of the base 2 is recessed to form a longitudinal adjustment threaded groove 56. The longitudinal threaded rod 54 passes through the base 2 and is installed in the longitudinal adjustment threaded groove 56. Rotating the longitudinal threaded rod 54 drives the longitudinal adjustment plate 52 to slide back and forth along the longitudinal adjustment groove 51, thereby realizing the adjustment of the longitudinal gap between the drawer and the guide rail.

[0027] A longitudinal adjusting nut 55 is installed on the top of the longitudinal threaded rod 54, and a longitudinal slot 22 is opened through the side wall of the base 2. The longitudinal adjusting nut 55 is fixed in the longitudinal slot 22.

[0028] The side end of the longitudinal adjustment plate 52 is inclined outward to form a longitudinal boss 53, which protrudes from the base 2 and presses against the guide rail.

[0029] Working principle: The quick-release mechanism for the drawer is equipped with a horizontal adjustment device, a vertical adjustment device, and an axial adjustment device, which are respectively embedded in the accommodating cavity enclosed by the base and the cover plate. The horizontal adjustment device, the vertical adjustment device, and the axial adjustment device are used to adjust the gap between the drawer and the drawer in the horizontal, vertical and axial directions, respectively.

[0030] The axial adjustment device includes an axial adjustment groove and an axial adjustment plate built into it, an axial adjustment nut that rotates within the axial fixing groove, and an axial threaded rod screwed onto the outside of the axial adjustment nut. Since the axial adjustment nut is fixedly engaged in the axial fixing groove, rotating the axial adjustment nut converts its rotational motion into linear motion of the axial threaded rod, pushing the axial adjustment plate forward or inward. The axial boss, formed by the inclination at the front end of the axial adjustment plate, presses against the guide rail, thereby adjusting the axial clearance between the drawer and the guide rail.

[0031] The lateral adjustment device includes a lateral adjustment groove and a lateral adjustment plate built into it, as well as a lateral adjustment threaded groove formed by a recess in the end face of the lateral adjustment plate, and a lateral threaded rod screwed into the lateral adjustment threaded groove. Since the lateral adjustment nut connected to the top of the lateral threaded rod is locked in a lateral slot opened in the side wall of the base, rotating the lateral adjustment nut converts the rotational motion of the lateral threaded rod into the linear motion of the lateral adjustment plate, pushing the lateral adjustment plate to move left and right. The lateral boss located at the side end of the lateral adjustment plate presses against the guide rail, thereby achieving adjustment of the lateral gap between the drawer and the guide rail.

[0032] The longitudinal adjustment device includes an axial adjustment groove and a longitudinal adjustment plate built into it, as well as a longitudinal adjustment threaded groove formed by a recess in the end face of the base, and a longitudinal threaded rod screwed into the longitudinal adjustment threaded groove. Since the longitudinal adjustment nut connected to the top of the longitudinal threaded rod is locked in a longitudinal slot on the side wall of the base, rotating the longitudinal adjustment nut converts the rotational motion of the longitudinal threaded rod into the linear motion of the longitudinal adjustment plate, pushing the longitudinal adjustment plate to move longitudinally. The longitudinal boss located at the side end of the longitudinal adjustment plate presses against the guide rail, thereby adjusting the longitudinal gap between the drawer and the guide rail.

[0033] The axial, lateral, and longitudinal clearance adjustments between the drawer and the guide rails can be completed with a simple rotation, requiring no complicated tools or disassembly of parts. This significantly reduces installation and adjustment time, making the adjustment process more intuitive, convenient, and efficient. Even after multiple adjustments, the quick-release mechanism maintains structural stability and durability. Furthermore, multi-directional clearance adjustments allow for quick correction of uneven clearances even during initial installation, ensuring precise drawer installation, improving accuracy, and guaranteeing stable and smooth drawer movement without jamming.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
