Three-axis parallel translation hinge

Abstract

Existing electromagnetic shielding door hinges adopt single-axis structures, some door hinges adopt dual-axis structures, and the reeds close to the door shaft sides are prematurely abraded or brokendue to extrusion. The invention discloses a three-axis parallel translation hinge, the three-axis and three-reed structure is adopted, on the basis of a limiting block, a limiting hole and a spring design, two segmented motions of rotation and translation are achieved, extrusion to the reeds is the smallest, and the maximum deformation amount of each reed is only a half the thickness of a blade. In this way, the service life of an electromagnetic shielding door can be greatly prolonged. The hinge is particularly suitable for some occasions where maintenance is not convenient for border defense, islands, ships and the like.

Description

technical field [0001] In the field of electromagnetic shielding room construction, the electromagnetic shielding effect and long-term use effectiveness of electromagnetic shielding doors are important indicators of the quality of electromagnetic shielding rooms. After the electromagnetic shielding door is closed, a high-performance conductive connection is realized through the highly conductive finger-shaped beryllium copper reed and the knife box between the door frame and the door leaf, so as to achieve a good electromagnetic shielding effect. technical background [0002] The existing domestic electromagnetic shielded door and the door frame use a single-axis hinge to realize the opening and closing of the door leaf. When the electromagnetic shielded door is closed, the door leaf takes the door shaft as the center and makes an arc track to mesh with the door frame. During the meshing process, the finger-shaped beryllium copper reed on the side of the door frame close to...
