Torsion spring rotating shaft and assembling method

Abstract

The invention discloses a torsion spring rotating shaft and an assembling method, the torsion spring rotating shaft comprises a first support, a second support, a sleeve, a torsion spring gasket, a torsion spring, a temporary assembling part and a formal assembling part, the assembling method of the torsion spring rotating shaft comprises the following steps: the first support and the sleeve penetrate into the temporary assembling part; a torsion spring is installed in the sleeve, one foot of the torsion spring is inserted into the first support, a torsion spring gasket is installed in the temporary assembly part, and then the other foot of the torsion spring is inserted into the torsion spring gasket; the first support is installed in the temporary assembly part, and the second support is locked on the first support; an angle adjusting gasket is installed in the formal assembly part, then the formal assembly part is aligned with the temporary assembly part, and the temporary assembly part is pushed to move forwards till the temporary assembly part is completely ejected out by the formal assembly part; a fastening piece is installed at the tail of the formal assembly piece, and after the fastening piece is adjusted to reach a proper torsion value, assembly of the torsion spring rotating shaft is completed; the torsion spring rotating shaft can be rapidly installed, the assembling difficulty is low, and the production capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and in particular relates to a torsion spring shaft and an assembly method. Background technique [0002] In the prior art, in clamshells or electronic products with rotating parts, such as notebook computers, torsion spring shafts are used to facilitate the opening and closing of the electronic products. [0003] At present, the assembly method of the torsion spring shaft is to use the pre-assembly method of the shaft. First, install the angle adjustment gasket into the rotating part, then put the sleeve into the rotating part, install the torsion spring on the sleeve, and install the torsion spring with one foot. For the large rotating plate, the other foot of the torsion spring is rotated by external force and loaded into the groove of the torsion spring gasket. In this installation method, the large rotating plate and the small rotating plate must be locked together with screws,...

Problems solved by technology

[0003] At present, the assembly method of the torsion spring shaft is to use the pre-assembly method of the shaft. First, install the angle adjustment gasket into the rotating part, then put the sleeve into the rotating part, install the torsion spring on the sleeve, and install the torsion spring with one foot. For the large rotating plate, the other foot of the torsion spring is rotated by external force and loaded into the groove of the torsion spring gasket. In this installation method, the large rotating plate and the small rotating plate must be locked together with screws, and the working angle of the torsion spring is relatively large. Large, the groove of the torsion spring spacer may be decoupled from one leg of the torsion spring, the assembly method is difficult, the operation is inconvenient, and it cannot meet the actual use needs
