Hinge special for instrument and apparatus

Abstract

The invention discloses a hinge special for an instrument and apparatus. The hinge comprises a rotating connecting shaft, an upward arrangement rotating rod is arranged above the rotating connecting shaft, an upward arrangement lengthening rod is arranged above the upward arrangement rotating rod, an upward arrangement locking device is arranged on the right side of the upward arrangement lengthening rod, a downward arrangement locking device is arranged on the left side of a downward arrangement lengthening rod, an automatic return spring device is arranged on the surfaces of the rotating connecting shaft, the upward arrangement rotating rod and the downward arrangement rotating rod, the top end of the automatic return spring device is connected with a first connecting piece, a left hingeleaf is arranged on the left side of the first connecting piece, the bottom end of the automatic return spring device is connected with a second connecting piece, a right hinge leaf is arranged on the right side of the second connecting piece, a right hinge leaf connecting hole is formed in the surface of the right hinge leaf, through the left hinge leaf, the right hinge leaf and the automatic return spring device, the problems that an existing hinge device is stressed mainly through a hinge structure on one face, after long-time use, the hinge device falls off easily, and an existing hinge cannot be automatically returned are solved.

Description

technical field [0001] The invention relates to the technical field of hardware products, in particular to a special hinge for instruments and meters. Background technique [0002] A hinge is a mechanical device used to connect two solids and allow them to rotate. Hinges are widely used and are often used on doors and windows. Many instruments and meters also need to be connected through hinges. Hinges are generally made of hinges. The shaft sleeve is generally formed by curling a part of the hinge sheet. Due to the processing technology or long-term use, the shaft sleeve will form a gap, and the lubricating oil between the shaft sleeve and the shaft will pass through the gap. Leakage, pollute the environment, cause noise when using the hinge, and also accelerate the deformation of the shaft sleeve, the shaft falls off or is stuck, etc., and finally the hinge cannot be used. [0003] For example, the application number is 201520754528.8, and the name is a hinge invention pa...

AI Technical Summary

Problems solved by technology

[0006] (1) The existing hinge device mainly relies on one side of the hinge structure to bear the force, which leads to the phenomenon that the hinge device is prone to fall off after long-term use;

[0007] (2) The existing hinge device cannot realize the function of automatic return after use
