Description

Technical Field

[0001] The invention relates to a guide rail quick release device, in particular to a guide rail quick release device with multi-dimensional adjustment. Background Art

[0002] Drawer rails generally include inner rails and outer rails. The two rails are connected by rolling balls. The inner rails are installed on the two side walls of the drawer, while the outer rails are installed on the two inner walls of the cabinet frame. The inner rails and the outer rails cannot be disassembled, which results in the drawer and the cabinet frame being unable to be separated. When arranging or moving furniture, the items inside the drawer must be completely cleaned before they can be moved. In order to solve the above-mentioned drawers, a quick release device is installed at the bottom of the drawer on the market for quick connection with the cabinet frame. The interlocking card seat of the quick release device is connected with the locking piece of the cabinet frame. When the drawer needs to be separated, the quick release device can be used to achieve the quick separation of the drawer. However, the installation accuracy required for the quick release device is relatively high. If there is a slight deviation during the installation process, it is easy to cause the outer rail and the inner rail to not be completely parallel and aligned, resulting in the problem that the drawer cannot be installed, thereby causing the drawer to be unable to slide smoothly or the sliding process to be stuck. At the same time, the installation method of the quick release device in the prior art is relatively fixed and lacks a flexible adjustment mechanism. Once there is a deviation during the installation process, it directly leads to uneven gaps between the drawer and the cabinet frame. Especially after drilling holes for installing the quick release, positional deviations require re-adjustment of the position and re-drilling, which can easily damage the integrity of the drawer or cabinet frame, resulting in high rework costs.

[0019] The axial fixing groove 44 passes through the base 2 , and the axial adjustment nut 46 embedded in the axial fixing groove 44 protrudes from the end surface of the axial adjustment plate 42 .

[0020] The front end of the axial adjustment plate 42 extends upward and tilts to form an axial boss 43 . The axial boss 43 protrudes from the base 2 and presses against the guide rail.

[0021] The transverse adjustment device includes a transverse adjustment groove 31 formed by a concave shape of the base 2, and a transverse adjustment plate 32 built into the transverse adjustment groove 31; the transverse adjustment device also includes a transverse threaded rod 34, and the end surface of the transverse adjustment plate 32 is concave to form a transverse adjustment threaded groove 36. The transverse threaded rod 34 passes through the base 2 and is installed with the transverse adjustment threaded groove 36. The transverse threaded rod 34 is rotated to drive the transverse adjustment plate 32 to slide left and right along the transverse adjustment groove 31, thereby realizing the adjustment of the transverse gap between the drawer and the guide rail.

[0022] A transverse adjustment nut 35 is installed on the top of the transverse threaded rod 34 , and a transverse slot 21 is provided through the side wall of the base 2 , and the transverse adjustment nut 35 is fixed in the transverse slot 21 .

[0023] The side end of the transverse adjustment plate 32 is inclined inward to form a transverse boss 33 . The transverse boss 33 protrudes from the base 2 and presses against the guide rail.

[0024] The longitudinal adjustment device includes a longitudinal adjustment groove 51 formed in 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 surface of the base 2 is recessed to form a longitudinal adjustment threaded groove 56.

[0026] The side end of the longitudinal adjustment plate 52 is inclined outward to form a longitudinal boss 53 . The longitudinal boss 53 protrudes from the base 2 and presses against the guide rail.

[0027] Working principle: In the guide rail quick release, a transverse adjustment device, a longitudinal adjustment device and an axial adjustment device are provided and respectively embedded in the accommodating cavity enclosed by the base and the cover plate. The transverse adjustment device, the longitudinal adjustment device and the axial adjustment device are used to adjust the transverse, longitudinal and axial gaps between the drawer and the guide rail respectively.

[0028] The axial adjustment device includes an axial adjustment groove and an axial adjustment plate built therein, an axial adjustment nut that is inserted into the axial fixing groove and rotates, and an axial threaded rod that is sleeved on the axial adjustment nut and is threadedly connected to the outside. Since the axial adjustment nut is fixedly inserted into the axial fixing groove, the axial adjustment nut is rotated to convert the rotational motion of the axial adjustment nut into the linear motion of the axial threaded rod, pushing the axial adjustment plate to extend forward or retract inward, and the axial boss formed at the front end of the axial adjustment plate pushes the guide rail, thereby adjusting the gap between the drawer and the guide rail in the axial direction.

[0029] The transverse adjustment device includes a transverse adjustment groove and a transverse adjustment plate built therein, and also includes a transverse adjustment thread groove formed by a depression on the end surface of the transverse adjustment plate, and a transverse thread rod screwed and installed with the transverse adjustment thread groove. Since the transverse adjustment nut connected to the top of the transverse thread rod is clamped and fixed in the transverse clamping groove provided in the side wall of the base, the transverse adjustment nut is rotated to convert the rotational motion of the transverse thread rod into the linear motion of the transverse adjustment plate, which pushes the transverse adjustment plate to move in the left and right directions, and the transverse boss located at the side end of the transverse adjustment plate pushes the guide rail to achieve the adjustment of the transverse gap between the drawer and the guide rail.

[0030] The longitudinal adjustment device includes an axial adjustment groove and a longitudinal adjustment plate built therein, a longitudinal adjustment thread groove formed by a depression on the end surface of the base, and a longitudinal threaded rod threadedly mounted on the longitudinal adjustment thread groove. The longitudinal adjustment nut connected to the top of the longitudinal threaded rod is fixed in the longitudinal groove provided on the side wall of the base by the longitudinal adjustment nut, and the longitudinal adjustment nut is rotated to convert the rotational motion of the longitudinal threaded rod into the linear motion of the longitudinal adjustment plate, which pushes the longitudinal adjustment plate to move in the longitudinal direction, and the longitudinal boss located at the side end of the longitudinal adjustment plate pushes the guide rail to achieve the longitudinal direction gap adjustment between the drawer and the guide rail.

[0031] The adjustment of the gap between the drawer and the guide rail in the axial, lateral and longitudinal directions only requires a simple rotation operation, without the need for complex tools, and the adjustment process does not require the removal of parts, which significantly shortens the installation and adjustment time, making the adjustment process more intuitive and convenient, with high adjustment efficiency, and ensuring the structural stability and durability of the quick release even after multiple adjustments. At the same time, through multi-directional gap adjustment, even if installation deviations occur during the initial installation, resulting in uneven gaps, they can be quickly corrected through adjustments, thereby achieving accurate installation of the drawer, improving installation accuracy, ensuring the normal and stable operation of the drawer, and smooth drawer sliding to avoid problems such as jamming.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
