Description

Technical Field

[0001] The utility model relates to the field of hinges, in particular to a torsion hinge which is easy to install and has a long service life. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. The hinge can be composed of movable components or foldable materials.

[0003] The existing torsion hinge structure can only adjust the torque to a smaller value during assembly and use, but cannot adjust it to a larger value, which results in relatively large limitations in use and inconvenience in use.

[0004] Therefore, it is necessary to provide a new torsion hinge which is convenient to install and has a long service life to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a torsion hinge which is easy to install and has a long service life, and solves the problem that the existing torsion hinge structure can only adjust the torque down but not up during assembly and use, thus resulting in large limitations in use and inconvenience in use.

[0006] The utility model provides a torsion hinge that is easy to install and has a long service life, comprising a first bushing, a second bushing and a pin shaft, wherein a mounting blade is fixed on one side of the first bushing and the second bushing, and a mounting hole is opened on the surface of the mounting blade;

[0007] A stopper is fixed at one end of the pin shaft, an external thread is arranged at the other end of the pin shaft, a threaded sleeve is threadedly installed on the pin shaft, a damping sleeve is arranged between the first bushing and the second bushing, and the damping sleeve is sleeved on the pin shaft;

[0008] A damping ring plate is provided at one end of the threaded sleeve, a damping groove is provided on the surface of the second bushing, the damping ring plate is inserted into the damping groove, and damping oil is coated between the damping groove and the damping ring plate;

[0009] A through hole is formed on the surface of the second bushing, and damping oil is filled between the second bushing and the pin shaft.

[0010] In a preferred embodiment, a rotating plate is mounted on the threaded sleeve, and a hexagonal groove is formed on the rotating plate.

[0011] In a preferred embodiment, a plug is provided at the through hole.

[0012] In a preferred embodiment, the first bushing, the second bushing and the pin are all made of aluminum alloy, and their surfaces are anodized and sandblasted.

[0013] Beneficial effects of the utility model:

[0014] 1. When assembling the torsion hinge, the user only needs to install the first bushing on the pin shaft so that one side of the first bushing contacts the block, put the damping sleeve on the pin shaft, put the second bushing on the pin shaft so that one side of the second bushing contacts the damping sleeve, and finally install the threaded sleeve on the pin shaft by a screwdriver so that the damping ring plate enters the damping groove to complete the assembly. The installation is simple and convenient, the structure is simple, and the cost is low.

[0015] 2. When the torque strength needs to be adjusted, the staff only needs to rotate the threaded sleeve to move it along the pin shaft. By adjusting the distance between the first bushing and the second bushing, different extrusion forces can be applied to the damping sleeve, so that the deformation degree of the damping sleeve changes, the friction between the damping sleeve and the two bushings changes, and then the torque strength changes;

[0016] 3. The first bushing, the second bushing and the pin are all made of aluminum alloy, and their surfaces are anodized and sandblasted to increase the service life of the hinge. The damping sleeve is made of wear-resistant rubber, which has low cost and long service life. BRIEF DESCRIPTION OF THE DRAWINGS
