Rotating shaft unit

Abstract

The invention provides a rotating shaft unit. The rotating shaft unit comprises a base, a rotating shaft and a pad, wherein the base does not deform under stamping; a rotating shaft capable of deformation under stamping is movably assembled into a shaft hole penetrating the base; the rotating shaft is provided with a head part pin-jointed in the shaft hole; a shaft column and a riveting part extending out of the shaft hole are arranged on the bottom surface of the head part; and the pad abutting against the bottom surface of the base is mounted on the shaft column. When the base is embedded ina first board in virtue of a butt joint part located at the outer side of the bottom, the riveting part can pass through a through hole in a second board, and the riveting part can be stamped throughstamping operation so as to allow the riveting part to deform and thus to abut against the inner wall surface of the through hole, so the first board and the second board can movably rotate relativeto each other in virtue of the base and the rotating shaft; and the pad is allowed to produce a damping frictional force during rotation, the rotation of the first board and the second board is allowed to be smoother and more stationary in virtue of the stamping riveting manner of the riveting part, and the thickness of the second board is reduced at the same time.

Description

technical field [0001] The invention relates to a rotating shaft device, especially a rotating shaft is installed in the shaft hole of the seat body, and a gasket is set on the shaft column of the rotating shaft. After the seat body is embedded in the first plate, the rotating shaft can be riveted by stamping The part is deformed and leans against the inner wall of the through hole of the second plate, and when the seat body and the rotating shaft rotate, the damping friction force generated by the gasket can be used to achieve the effect of making the rotation stable. Background technique [0002] Press, the general shaft system provides mutual connection between two components, and enables one of the components to rotate relative to the other to have the function of rotation, and many products will use the shaft structure, such as doors, windows, and telecom cabinets. , industrial computer, work machine, etc., the shaft can be used as a door panel, window panel, frame pane...

AI Technical Summary

Problems solved by technology

[0004] However, the rotating shaft A is a unitary component and is passed through the through hole B1 of the first plate B and the through hole C1 of the second plate C. When the first plate B and the second plate C rotate relative to the axis A , it will cause the through hole B1 and the through hole C1 to easily have a large area of ​​contact and friction with the stop body A1 and the buckle end A2 of the rotating shaft A, resulting in the relative rotation of the first plate B and the second plate C. It is quite unsmooth due to a lot of resistance. If the first plate B or the second plate C is rotated with force, it will also cause burrs and debris to be easily generated on the rotating shaft A to form a jamming phenomenon. After excessive friction, a large gap will be formed, and then there will be looseness between the shaft A and the first plate B and the second plate C, and even yaw or tilting will occur, and the overall structural stability is also poor. It is difficult to meet the requirements of practicability, which is the direction for those who are engaged in this industry to study and improve.
