Description

Technical Field

[0001] The utility model relates to a furniture hardware fitting, in particular to a drawer quick-release connector. Background Art

[0002] In modern furniture design, as an important part of furniture, the design and installation method of drawers directly affect the use experience of furniture. Most of the existing drawer connectors rely on screws or buckles for fixation. Although this traditional connection method can meet the basic requirements in terms of stability, it often requires tools for installation and disassembly, with complex operations and time-consuming processes. Especially in the case of frequent disassembly or replacement of drawers, this method is particularly inconvenient.

[0003] Some quick-release connectors have emerged on the market, attempting to simplify the connection and separation process between drawers and rails. However, these quick-release connectors generally have problems such as complex structures, high manufacturing costs, and numerous installation steps. Their designs usually require multiple independent components to achieve adjustment and fixation in different directions, which not only increases the difficulty of production and assembly but also easily leads to problems such as loosening and wear during long-term use, affecting the stability and service life of the drawers.

[0004] For example, some existing quick-release connectors use spring or latch structures to achieve quick connection and disassembly. However, due to design deficiencies, these structures are prone to jamming or loosening during use, resulting in unsmooth movement of the drawers on the rails. In addition, while some connectors achieve quick disassembly and assembly, they ignore the gap adjustment and fixation between the drawers and rails, and cannot effectively solve the problem of drawer wobbling during use, affecting the use experience. Therefore, it is necessary to make further improvements to it. Summary of the Utility Model

[0031] In one embodiment: the elastic squeezing member is an elastic strip 21 provided at the bottom of the docking area 2, and the elastic strip 21 extends obliquely into the docking area 2.

[0032] In one embodiment: the elastic strip 21 and the main body 1 are integrally made of plastic material, and the inclination angle between the elastic strip 21 and the bottom of the docking area 2 is set to be 20° to 35°.

[0033] In one embodiment: the elastic squeezing member includes a sliding groove 11 provided on the main body 1. An elastic top block 12 is slidably installed in the sliding groove 11. An extrusion spring 13 is provided between the elastic top block 12 and the main body 1. The extrusion spring 13 pushes the elastic top block 12 to always extend into the docking area 2.

[0034] In one embodiment: the sliding groove 11 is in a convex shape with a wider front and a narrower rear. Correspondingly, a limiting portion 14 extending to both sides is provided at the tail of the elastic top block 12. The limiting portion 14 slides in the main body 1 of the sliding groove 11 to limit the movement stroke of the elastic top block 12.

[0035] In one embodiment: a threaded post 41 extends horizontally from the side wall of the lateral adjusting member 4. The lateral adjusting seat 5 is rotatably installed in the lateral adjusting groove 42 of the main body 1. A threaded hole 51 is provided on the lateral adjusting seat 5 and is screwed with the threaded post 41. Rotating the lateral adjusting seat 5 drives the lateral adjusting member 4 to perform a lateral displacement.

[0036] In one embodiment: the vertical adjusting member 6 includes a wedge block 61 with a triangular cross section, and a vertical adjusting seat 62 connected to the side wall of the wedge block 61. A vertical driving handle 63 is provided on the vertical adjusting seat 62. The vertical adjusting seat 62 is slidably installed in a vertical adjusting groove 64 located on the main body 1.

[0037] In one embodiment: a vertical clearance groove 65 is also provided on the main body 1. The vertical driving handle 63 extends into the vertical clearance groove 65.

[0038] In one embodiment: the longitudinal buckle 9 is slidably mounted in a longitudinal slideway 92 on the main body 1. One end of a quick-release wrench 91 is hinged to the main body 1. A driving arm 93 is also hingedly mounted on the main body 1. One end of the driving arm 93 is connected to the quick-release wrench 91, and the other end is hinged to the longitudinal buckle 9. When the quick-release wrench 91 moves, the longitudinal buckle 9 is driven by the driving arm 93 to move in the longitudinal chute 11.

[0039] In one embodiment: a longitudinal push spring is arranged between the longitudinal chute 11 and the longitudinal buckle 9, and the longitudinal push spring generates a thrust force that always pops out towards the docking area 2.

[0040] Working principle: As Figures 1-3 shown, when the drawer is installed on the guide rail, the docking area 2 is docked with the head of the guide rail 3. An elastic extrusion member is arranged at the bottom of the docking area 2. The elastic extrusion member is an elastic strip 21. When the drawer is docked with the guide rail, the elastic strip 21 obliquely extends into the docking area 2 and presses against the tail of the guide rail 3. Through this design, the elastic strip 21 provides a continuous elastic pressure, ensuring a tight contact between the drawer and the guide rail and preventing loosening. In addition, in order to avoid the elastic force attenuation of the elastic member made of plastic material after being used for a period of time, a chute 11 is also arranged on the main body 1. An elastic top block 12 is slidably mounted in the chute 11. An extrusion spring 13 is arranged between the elastic top block 12 and the main body 1, and the extrusion spring 13 pushes the elastic top block 12 to always extend into the docking area 2. By using the elastic thrust generated by the extrusion spring, the precise connection in the longitudinal direction between the guide rail and this quick-release device is always maintained, avoiding displacement between the guide rail and the drawer during the later pulling of the drawer.

[0041] In addition, a transverse adjustment member 4 is also arranged at the bottom of the docking area 2. It is inserted into the head of the guide rail and is connected to the main body 1 through a transverse adjustment seat 5. A threaded column 41 extends horizontally from the side wall of the transverse adjustment member 4. The transverse adjustment seat 5 is rotatably mounted in a transverse adjustment groove 42 on the main body 1 and is screwed to the threaded column 41 through a threaded hole 51. By rotating the transverse adjustment seat 5, the transverse adjustment member 4 can be driven to perform a transverse displacement, thereby realizing precise adjustment of the transverse gap between the drawer and the guide rail.

[0042] In addition, a vertical adjustment member 6 is also arranged on the side wall of the docking area 2. It is inserted between the guide rail and the drawer 7 to squeeze the gap between them and is connected to the main body 1 through a vertical adjustment seat 62. The vertical adjustment member 6 includes a wedge block 61 with a triangular cross-section and a vertical adjustment seat 62. A vertical driving handle 63 is arranged on the vertical adjustment seat 62, and precise positioning of the vertical adjustment member is achieved through the engagement of a movable tooth 66 with a fixed rack 67, ensuring the stability of the drawer in the vertical direction.

[0043] In addition, a longitudinal buckle 9 is provided on the side wall of the docking area 2, which is connected to the main body 1 through a quick-release wrench 91. The longitudinal buckle 9 is slidably installed in the longitudinal slideway 92. One end of the quick-release wrench 91 is hinged to the main body 1 and is connected to the longitudinal buckle 9 through a driving arm 93. When the quick-release wrench 91 moves, it drives the longitudinal buckle 9 to move in the longitudinal slideway 92 to achieve docking or separation with the quick-release opening on the guide rail 3. The longitudinal push spring always provides a thrust force towards the docking area 2 to ensure the automatic reset of the longitudinal buckle 9, so that the longitudinal buckle is always forced to move towards the guide rail direction to maintain its locking force.

[0044] Compared with the traditional technology, in this case, through the design of the quick-release wrench and the longitudinal buckle, the quick docking and separation of the drawer and the guide rail are realized. The user can easily complete the installation and disassembly without the aid of tools, significantly improving the operation efficiency.
