Description

Technical Field

[0001] This utility model relates to the technical field of drawer slides, and in particular to a quick-release fixing device for drawers and drawer slides. Background Technology

[0002] The handle connects the drawer and the slide rail. It is fixed to the underside of the drawer's bottom plate and inserts into the hole in the slide rail via a protruding tongue, allowing the drawer and slide rail to move synchronously. Similarly, patent application number 202122276619.3 discloses a three-dimensional adjustable handle for a slide rail drawer. This type of handle requires tools to drive screws to secure it to the bottom of the drawer during assembly. However, the handle must be aligned precisely during assembly; otherwise, misalignment between the handle and the slide rail will occur, resulting in an unsatisfactory assembly and wasting time and effort. While the handle can be pre-fixed to the bottom of the drawer during shipping to solve this problem, only a portion of the handle is fixed to the drawer, leaving most of it suspended. This makes the handle susceptible to damage in the event of impacts. Utility Model Content

[0021] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0022] Reference Figures 1 to 5 A quick-release fixing device for drawers and slide rails includes a fixing base 1 for fixing to the drawer, and a connecting part 2 connected to the fixing base 1 and capable of being inserted into the slide rail. A connecting structure 3 for detachable connection between the fixing base 1 and the connecting part 2, and a snap-fit ​​structure 4 for fixing the connecting part 2 to the fixing base 1 are provided. This separates the quick-release fixing device into two parts: the fixing base 1 and the connecting part 2. This facilitates transportation and assembly. During transportation, because the connecting part 2 is separate from the fixing base 1, it avoids the connecting part 2 being suspended in the air and having a long protruding length when connected to the fixing base 1, thus preventing easy damage in the event of impact. During assembly, since the fixing base 1 is pre-installed on the bottom of the drawer before shipment, the user only needs to insert the connecting part 2 into the fixing base 1 to complete the assembly. The entire process can be completed without the use of tools or alignment, making it simple and quick.

[0023] In this design, the connecting structure 3 includes a groove 31 located on the front side of the fixed base 1 and a sliding rib 32 located on the rear side of the connecting part 2 that can cooperate with the groove 31. Through the sliding engagement of the sliding rib 32 and the groove 31, the connecting part 2 can be assembled onto the fixed base 1. Furthermore, the sliding rib 32 is T-shaped. The connecting structure 3 includes several first protrusions 33 located on its rear side and above, and several second protrusions 34 located on its rear side and below. Both the first protrusions 33 and the second protrusions 34 are L-shaped, so that the first protrusions 33 and the second protrusions 34 combine to form a T-shaped groove 31. The shape of the groove 31 matches the shape of the sliding rib 32, making the engagement between the two more stable and less prone to separation.

[0024] In this design, the first protrusion 33 and the second protrusion 34 are staggered, forming a hollow shape to save manufacturing materials. Furthermore, there are two first protrusions 33 and one second protrusion 34, arranged from left to right in the order of first protrusion 33, second protrusion 34, and then first protrusion 33. This creates a notch in the lower left of the slide groove 31, facilitating the insertion of the sliding rib 32 into the slide groove 31 from below. Preferably, the edge of the inserted end of the sliding rib 32 is chamfered, allowing for smoother insertion into the slide groove 31.

[0025] In this design, the latching structure 4 includes a latching groove 41 located on the front side and lower left of the fixing base 1, and an elastic latch 42 located on the rear side of the connecting part 2 and capable of being inserted into the latching groove 41. A groove 21 is provided on the rear side and lower left of the connecting part 2, and the elastic latch 42 is disposed on the side wall of the groove 21. When the sliding rib 32 is inserted into the sliding groove 31, the sliding rib 32 will press the elastic latch 42 into the groove 21. Then, after the sliding rib 32 slides to the corresponding position, the elastic latch 42 will pop out and latch into the latching groove 41, thus fixing the connecting part 2 and the fixing base 1 together. Furthermore, the lower end of the elastic latch 42 extends downwards with a lever 421 protruding from the lower side of the connecting part 2. This allows the elastic latch 42 to be pressed into the groove 21 by hand, thereby unlocking the latching structure 4 and detaching the connecting part 2 from the fixing base 1.

[0026] In this solution, a limiting protrusion 11 is provided on the front side and at its right end of the fixing base 1, and a limiting groove 22 that cooperates with the limiting protrusion 11 is provided on the rear side of the connecting part 2, so as to limit the position of the sliding rib 32 inserted into the sliding groove 31, so that the elastic buckle 42 can be better engaged with the buckle groove 41.

[0027] In this solution, the rear side of the fixing seat 1 is provided with a recess 12 for fixing to the drawer, and a threaded hole is provided on the bottom surface of the recess 12, so that the fixing seat 1 and the drawer are connected by a threaded connection, thereby locking the fixing seat 1 to the drawer.

[0028] In this design, the connecting part 2 includes a tongue 23 that can be inserted into the slide rail, and a pressing structure 24 that controls the left and right movement of the tongue 23. Specifically, the tongue 23 can move left and right within the cavity of the connecting part 2 to insert into the insertion hole of the slide rail, thereby fixing the connecting part 2 to the slide rail. The pressing structure 24 includes a pressing member 241 that engages with the tongue 23, and a spring 242 disposed within the cavity of the connecting part 2 and capable of resetting the tongue 23. The pressing member 241 is hinged within the cavity of the connecting part 2 and can swing left and right, thereby driving the tongue 23 to move left and right.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
