Abstract
Description
Technical Field
[0001] The utility model relates to the field of hinges, in particular to a hinge with a special-shaped bushing. Background Art
[0002] A hinge is mainly composed of a first pressing plate and a second pressing plate, which are hinged between the first pressing plate and the second pressing plate. In order to make the connecting shaft between the first pressing plate and the second pressing plate have a longer service life, a bushing is fixedly arranged in the hinge. The connecting shaft is arranged in the bushing to prevent damage caused by contact with the rigid material hinge. Therefore, the bushing is the main component to extend the service life of the hinge. At present, the bushing is fixed in the hinge in an interference fit manner. However, after long-term use, the bushing is prone to loosen and rotate in the hinge, and the bushing is easily worn and damaged, affecting the normal use of the hinge. Content of the Utility Model
[0003] The utility model solves the problem that the bushing structure in the existing hinge is not stable enough and is easily rotated and damaged.
[0004] The technical solution adopted by the utility model is: a hinge with a special-shaped bushing, including a pressing plate and a bushing. A convex bushing installation part is arranged on one side of the pressing plate. A bushing installation groove is arranged in the bushing installation part. A first installation groove and a second installation groove are arranged in the bushing installation groove. The first installation groove and the second installation groove communicate with each other. The first installation groove is set as a circular structure. The second installation groove is set as a square structure. The included angle of the second installation groove is set as an arc chamfered corner structure.
[0005] The bushing has a first installation part and a second installation part. The first installation part is arranged at the bottom of the second installation part. The first installation part is set as a cylindrical structure. The second installation part is set as a square structure. The included angle of the second installation part is set as an arc chamfered corner structure.
[0006] The bushing is arranged in the bushing installation groove. The first installation part is arranged in the first installation groove. The second installation part is arranged in the second installation groove.
[0007] Furthermore, the included angle of the second installation groove is set as a right angle structure, and the included angle of the second installation part is correspondingly set as a right angle structure according to the second installation groove.
[0008] The beneficial effect of the utility model compared with the prior art is that: the bushing is arranged in the bushing installation groove. The first installation part is arranged in the first installation groove. The second installation part is arranged in the second installation groove. The design of the bushing and the installation groove is precisely optimized, which can provide better stability and prevent the bushing from rotating in the pressing plate.

[0015] As Figures 1 to 5 described, a hinge provided with a special-shaped bushing includes a pressing plate 10 and a bushing 20. A convex bushing installation part 30 is provided on one side of the pressing plate 10. A bushing installation groove 31 is provided in the bushing installation part 30. A first installation groove 32 and a second installation groove 33 are provided in the bushing installation groove 31. The first installation groove 32 and the second installation groove 33 communicate with each other. The first installation groove 32 is set as a circular structure. The second installation groove 33 is set as a square structure. The included angle of the second installation groove 33 is set as an arc-shaped rounded corner structure.
[0016] The bushing 20 has a first installation part 21 and a second installation part 22. The first installation part 21 is arranged at the bottom of the second installation part 22. The first installation part 21 is set as a cylindrical structure. The second installation part 22 is set as a square structure. The included angle of the second installation part 22 is set as an arc-shaped rounded corner structure.
[0017] The bushing 20 is arranged in the bushing installation groove 31. The first installation part 21 is arranged in the first installation groove 32. The second installation part 22 is arranged in the second installation groove 33. The design of the bushing 20 and the installation groove is precisely optimized, which can provide better stability and prevent the bushing 20 from rotating in the pressing plate 10.
[0018] The included angle between the second installation groove 33 and the second installation part 22 is not limited to the rounded corner structure. The included angle of the second installation groove 33 can also be set as a right angle structure, and the included angle of the second installation part 22 is correspondingly set as a right angle structure according to the second installation groove 33.
