Abstract

The invention relates to a reciprocating type locking hinge, and belongs to the technical field of sofa accessories. According to the reciprocating type locking hinge, operation in a single clamping position mode with the cooperation of a locking plate, a movable locking block, an elastic pressing device and an arc-shaped locking groove of a rotary driving plate is adopted to enable locking teethto be engaged or disengaged, and effective operation is performed in different directions of y1 and h1 to acquire a lock state and a return state. The reciprocating type locking hinge has the advantages of being stable in operation, smooth and flexible in gear shifting, simple and convenient to assemble and large in operation angle.

Description

technical field [0001] The invention belongs to the technical field of sofa accessories, and refers to a reciprocating locking hinge. Background technique [0002] With the modernization of society, sofas have gradually entered every household, and the locking hinge can make the sofa adjust to the most comfortable angle within a certain angle. The existing sofa hinge has the following three problems due to the imperfect structure: first, the rotation is not stable, the stability is poor, and it is prone to failure; second, the structure is complex, the shifting is not flexible, and the processing and assembly are difficult Large; Third, the arc-shaped lock groove and the lock teeth on the movable lock block are all set on the inner side, and the operating angle is limited. Contents of the invention [0003] The object of the present invention is to provide a reciprocating locking hinge with stable operation, smooth and flexible transition, easy assembly and large operatin...
