Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-4, a rotating shaft comprises a structure body, the structure body is composed of a connecting shaft 2 and a fixed frame 1 and a movable frame 4 which are respectively sleeved at two ends of the connecting shaft 2, a connecting shaft limit 10 which is formed integrally with the connecting shaft 2 through vehicle punching is arranged on the connecting shaft 2, the connecting shaft limit 10 is arranged between the fixed frame 1 and the movable frame 4, one side of the movable frame 4, which is far away from the fixed frame 1, is sequentially provided with a convex gasket 3, a spring gasket 6, a flat gasket 7 and a nut 8 which are sleeved on the connecting shaft 2, the bottom of the movable frame 4 is provided with an elastic sheet 5, and the elastic sheet 5 is in contact connection with the convex part of the convex gasket 3.

Wherein, spring shim 6 is no less than two sets ofly, be equipped with a plurality of rivets 9 on the convex shim 3, convex shim 3 with adjustable shelf 4 passes through rivet 9 realizes fixed connection, connecting axle 2 with the nut 8 junction is equipped with the screw thread, convex shim 3, spring shim 6 and dull and stereotyped gasket 7 pass through nut 8 is fixed in adjustable shelf 4 with between the nut 8, mount 1 with 2 joint formulas of connecting axle are connected, adjustable shelf 4 with 2 swivelling joint of connecting axle, convex shim 3, with dull and stereotyped gasket 7 joint in on the connecting axle 2.

It should be noted that the connecting shaft limiting part 10 is an arc-shaped structure provided with a 100-degree notch, the movable frame 4 is provided with a limiting block 11 on one side close to the fixed frame 1, and the limiting block 11 is located in the 100-degree notch.
