Linkage locking structure of hinge

Abstract

The invention discloses a linkage locking structure of a hinge. The structure comprises a movable cup base, a connecting arm and a fixed base; one end of the connecting arm is matched and connected with the movable cup base, and the other end is matched and connected with the fixed base; the movable cup base and the fixed base are mutually hinged through the connecting arm for opening and closing; a front-back linkage locking device is arranged between the connecting arm and the fixed base; and the connecting arm is arranged above the fixed base from top to bottom, and is matched and connected with the fixed base through the front-back linkage locking device. Through improvement of the structure, users can firstly fix the fixed base, and then, hands are used for righting the connecting arm to assemble on the fixed base from top to bottom, so that the disassembly of the connecting arm and the fixed base by the users is more convenient; and the structure has such characteristics as simple and reasonable structure, excellent performances, fast assembly, convenience in operation, flexible assembly, less occupied space, low production cost, easiness in production, easiness in realization, safety and reliability, and is high in practicability.

Description

technical field [0001] The invention relates to a linkage locking structure of a hinge. Background technique [0002] Chinese Patent Document No. CN204850833U disclosed a fixed base structure of a furniture hinge on December 9, 2015. It includes an articulated arm, a fixed base and a movable cup holder. The articulated arm is provided with an elastic clamping assembly and an intermediate arm. There are at least two buckle positions on the top, the fixed base includes a holding element and a fixing element, an adjusting element is arranged between the holding element and the fixing element, the fixing element is placed at the bottom of the holding element, and the two are slidably fitted through a sliding fit, The adjustment element is placed at the rear end of the holding element, and the action part of the adjustment element is acted on by a tool. The adjustment element drives the holding element to slide left and right relative to the fixed element, so as to realize the re...

Problems solved by technology

When the hinge is assembled, the front end of the intermediate arm is used as the fulcrum, and the fulcrum is used to rotate, and then the elastic snap-fit ​​assembly at the rear end of the intermediate arm is detachably connected with the fixed base. It is a rotating type, which requires a certain position for the rotation of the intermediate arm during assembly. If the position is not enough, the intermediate arm cannot be rotated, that is, the entire hinge cannot be assembled, which cannot meet the needs of users.
