Three-rotating-shaft door hinge and door lock structure applying same

Abstract

The door lock structure comprises a three-rotating-shaft door hinge, a plurality of pressing air cylinders, a plurality of pulling plates, a limiting wheel and a detection device, and the three-rotating-shaft door hinge is connected with one end of a cavity and one end of a cavity door; the three-rotating-shaft door hinge comprises an upper door installation base, a lower door installation base, a through shaft, a rear swing arm, an upper container installation base, a lower container installation base and a translation air cylinder. The action process is that the telescopic rod of the linear motion mechanism stretches out or contracts, the rear swing arm is pushed to rotate, the through shaft and the cavity door are driven to horizontally move, and then the cavity door is closed or opened by manually operating the handle. Compared with a traditional double-shaft door hinge, the three-rotating-shaft door hinge has the advantages that the degree of freedom of a mechanism is higher, the cavity door can horizontally move besides circumferential rotation, obstruction of the front end of the cavity door can be effectively avoided, more complex conditions can be dealt with, the three-rotating-shaft door hinge can be suitable for more occasions and environments, hinge transmission is reserved, and the three-rotating-shaft door hinge is simple, light and durable in structure.

Description

technical field [0001] The invention relates to the field of multi-degree-of-freedom door hinges, in particular to a three-axis door hinge and a door lock structure using the three-axis door hinge. Background technique [0002] The existing vacuum chamber door hinge is basically a double-axis door hinge, and the chamber door is opened by rotating the door hinge by a person or other power source of a cylinder. The double-axis door hinge usually limits the through shaft and the cavity door, and only allows a small angle of relative rotation to protect the sealing ring. The degree of freedom of the mechanism is 1, so the movement path is unique and fixed. Conflicting motion paths of the cavity doors result in limited use of the dual-axis door hinges. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a three-axis door hinge and a door lock structure using the three-axis door hinge, so that the ...

Problems solved by technology

Biaxial door hinges usually limit the through shaft and the chamber door, and only allow a small angle of relative rotation to protect the sealing ring. The degree of freedom of the mechanism is 1, so the movement path is unique and fixed. In practical applications, the site or equipment may be different from the Conflicting motion paths of the chamber doors, resulting in limited use of dual-axis door hinges
