Embodiment

[0038] Each cover mechanism comprises parts such as locking bar, guide ring and connecting rod among the present embodiment. There is an opening in the center of the cover, and a lock cylinder is installed in the opening to operate the locking and unlocking of the cover mechanism. There are four protruding lugs around it, and the lugs are connected with the locking bar through a connecting rod. , the locking rod moves linearly along the guide ring. The lock core moves along the normal direction of the mouth cover under the action of the limit block, and a spring is arranged between the lock core and the limit block.

[0039] When the spring is in the longest state, the lugs, connecting rods and locking rods are in the over dead point position, the locking rod is stretched out, inserted into the locking ring on the mouth frame, and the lid lock mechanism is in a locked state, as figure 2 shown. Under the action of the spring, the lock cylinder remains in the locked position,...

Abstract

The invention discloses an opening cover lock device based on a linkage mechanism. The opening cover lock device comprises lock holes formed in an opening frame as well as a limiting block, a lock cylinder, a spring, connecting rods, lock rods and guide rings which are arranged on an opening cover. According to the opening cover lock device, a double-slider mechanism is adopted, the lock cylinderis one slider, the lock rods are another sliders, under the action of an unlocking structure, through the opening cover lock device, the lock cylinder linear movement perpendicular to the opening cover plane is converted into the lock rod linear movement parallel with the opening cover plane through transfer by the aid of the connecting rods, the thickness of tabs at the head of the unlocking structure is designed according to the lock cylinder unlocking travel, after the lock cylinder is moved in place, the unlocking structure is expanded automatically under the action of the middle spring, the link of manual in-place unlocking judgment is omitted, and the unlocking operation is simplified.

Description

technical field [0001] The invention relates to a flap lock device based on a linkage mechanism, which is used to realize fast installation and disassembly of a flap, and belongs to the technical field of mechanism device design. Background technique [0002] On mechanical equipment, due to considerations such as maintenance, it is necessary to have a maintenance operation port on it, and at the same time, a closed cover is provided at the operation port. In the prior art, most of the maintenance port covers are provided with multiple locking points and operation ports. To ensure the strength and rigidity of the connection, it is generally installed and fixed by using multiple screw nuts or using a quick lock device that operates each locking point separately. When installing the cover, each locking point needs to be checked one by one. To operate, the operation time is longer. Therefore, the traditional flap connection method is not suitable for flaps that often need to be...
