Description

Technical Field

[0001] This application relates to a self-adjusting damping hinge, belonging to the field of lock fittings technology. Background Technology

[0002] A hinge, also known as a joint, is a mechanical component used to connect two solid objects and allow relative rotation between them. It is used in doors, windows, cabinets, and other similar installations. A hinge typically consists of a bolt and two hinges mounted on the bolt. During use, the hinges rotate relative to the bolt based on the threaded connection between the bolt and the hinges. This movable connection can become unstable under vibration or prolonged use, leading to loosening of the connection and potentially causing it to collapse or fall off. This compromises the structural and structural stability of the connected components. Utility Model Content

[0003] In view of this, this application provides a self-adjusting damping hinge that can achieve automatic adjustment during rotation and improve the stability of the connection.

[0004] Specifically, this application is implemented through the following scheme: A self-adjusting damping hinge includes a first hinge component, a second hinge component, and a linkage mechanism connecting the first hinge component and the second hinge component. A wedge-shaped component is fitted onto the linkage mechanism, and the wedge-shaped component is positioned corresponding to the junction of the first hinge component and the second hinge component. The wedge-shaped component has a tapered structure with one end larger than the other, and the larger end and the smaller end are located inside the first hinge component and the second hinge component, respectively.

[0005] Furthermore, as a preferred option: The first hinge component includes a first fixed plate and a first hinge plate. The second hinge component includes one second fixed plate and two second hinge plates. The first fixed plate and the second fixed plate are located on opposite sides of the linkage mechanism. The first hinge plate and the second hinge plate are respectively fitted onto the linkage mechanism, with the first hinge plate fitted in the middle of the linkage mechanism and the two second hinge plates located on either side of the first hinge plate. More preferably, the first fixed plate is provided with a retaining groove, and / or the second fixed plate is provided with a retaining groove. The first fixed plate is provided with a fixing hole, and / or the second fixed plate is provided with a fixing hole.

[0006] Two wedge-shaped components are provided.

[0007] The linkage mechanism includes a connecting rod and a fastening nut. One end of the connecting rod is fixed to a first hinge member, and the other end passes through a second hinge member and is fixed with a fastening nut. The connecting rod is connected to the first and second hinge members by a wedge-shaped member. More preferably, the connecting rod includes a rod body and a nut end. The rod body is threaded, and the nut end is integrally formed with or fixed to the rod body. The fastening nut is threaded onto the end of the rod body away from the nut end. In this case, when there are two wedge-shaped members, they include a first wedge and a second wedge. The large end of the first wedge abuts against the inner side of the nut end of the connecting rod, and the large end of the second wedge abuts against the inner side of the fastening nut, and its position on the connecting rod is controlled by the fastening nut. Preferably, a sealing element is fitted between the large end of the first wedge and the nut end of the connecting rod.

[0008] The large end and the small end of the wedge-shaped member are connected by an inclined plane.

[0009] In use, the first and second fixing plates are fixed between the two mechanisms to be connected, so that one hinge component is fixed relative to the other hinge component, while the other hinge component can swing around the linkage mechanism. During the swinging process, by controlling the position of the wedge component on the linkage mechanism, such as by screwing in or out the fastening nut, the wedge component can be made to go deeper or out relatively, thereby changing the tightness of the connection between the wedge component and the linkage mechanism and the first and second hinge plates. This achieves the tightness of the connection between the two hinge components and the linkage mechanism, realizes the automatic adjustment function of the damping hinge, and avoids the hinge plate from loosening from the linkage mechanism during the swinging process.

[0012] This embodiment provides a self-adjusting damping hinge, such as Figure 1 , Figure 2 As shown, it includes a first hinge component 1, a second hinge component 2, and a linkage mechanism connecting the first hinge component 1 and the second hinge component 2.

[0013] The first hinge component 1 includes a first fixed plate 11 and a first hinge plate 12. The second hinge component 2 includes a second fixed plate 21 and two second hinge plates 22. The first fixed plate 11 and the second fixed plate 21 are located on both sides of the linkage mechanism. The first hinge plate 12 and the two second hinge plates 22 are respectively fitted onto the linkage mechanism. The first hinge plate 12 is fitted onto the middle of the linkage mechanism, while the two second hinge plates 22 are located on both sides of the first hinge plate 12.

[0014] Combination Figure 3 , Figure 4 The linkage mechanism includes a link 3 and a fastening nut 6. The link 3 includes a rod body 32 and a nut end 31. The nut end 31 and the rod body 32 are an integral structure, and the diameter of the nut end 31 is larger than that of the rod body 32. The rod body 32 is threaded, and a fastening nut 6 is installed at the end of the rod body 32 (i.e., the end away from the nut end 31).

[0015] A wedge-shaped component, which is a conical structure with one end larger than the other, is fitted on the connecting rod 3. The wedge-shaped component includes two components: a first wedge 4 and a second wedge 5. The two wedge-shaped components have the same structure and are both fitted on the rod 32, but their installation positions are different. Specifically, the first wedge 4 is located on the side closer to the nut end 31. To ensure the tightness of the installation, a sealing element 7 (such as a sealing ring) can be fitted on the rod 32. The sealing element 7 is located inside the first wedge 4 and the nut end 31. The second wedge 5 is located on the rod 32 inside the fastening nut 6.

[0016] To avoid locking and affecting the hinge's movement, combined with Figure 4 There is a certain amount of space for movement between the first wedge 4 and the second wedge 5.

[0017] In the above construction, combined Figure 4 and Figure 5The wedge-shaped component has a structure with one end larger than the other. Taking the second wedge 5 as an example, its structure can be specifically configured to include a small end 51, an inclined surface 52, and a large end 53. The inner diameter of the cavity in the first hinge plate 11 is relatively small, while the inner diameter of the cavity in the second hinge plate 21 is relatively large. The outer diameter of the large end 53 and the nut end 31 is adapted to the inner diameter of the cavity in the second hinge plate 21, and the outer diameter of the small end 51 is adapted to the inner diameter of the cavity in the first hinge plate 11. The diameter of the large end 53 decreases towards the small end 51 to form a smooth inclined surface 52, which is located at the corresponding position at the junction of the first hinge plate 11 and the second hinge plate 21. For the first wedge 4, its large end 53 is tightened between the rod body 32 and the inner wall of the cavity of one of the second hinge plates 21 by screwing the fastening nut 6 into the thread of the rod body. For the second wedge 5, its large end abuts against the inner side of the nut end 31 and is sealed with a sealing member 7.

[0018] Combination Figure 1 , Figure 2 A buckle groove 13 can also be provided on the first fixing plate 11. The buckle groove 13 can be set in the center position. The buckle groove 13 and the remaining part of the first fixing plate 11 form a handle structure, which makes it easy to grab the first fixing plate 11. A fixing hole 14 can also be provided on the first fixing plate 11. Screws and other components pass through the fixing hole 14 to fix the first fixing plate 11 to the corresponding cabinet door and other components.

[0019] The second hinge component 2 can also be provided with a latching groove, fixing hole, etc., just like the first hinge component 1, to facilitate installation.

[0020] During use, the first wedge 4 can be moved outward along the body of the rod (moving towards the nut end 31 is considered as moving inward) by adjusting the fastening nut 6, thereby changing the tightness of the first wedge 4 between the rod body 32 and the inner wall of the cavity of the second hinge plate 21; when the first hinge 1 and the second hinge 2 become loose, the wedge component with a relatively fixed position will also block their displacement, realizing automatic adjustment, thereby avoiding the loosening of the hinge and linkage mechanism caused by vibration and swing.
