Secondary opening cover cap lock and working method thereof

Abstract

The invention relates to a secondary opening cover cap lock which comprises a housing as well as a clamping board and a clamping claw which are in mutual secondary locking matching, wherein the clamping board comprises a clamping board engaged part; a primary engaged region and a secondary engaged region are arranged on the surface of the clamping board engaged part; the clamping claw comprises a primary locking engaged part and a secondary locking engaged part; the primary engaged region is in contact matching with the primary locking engaged part; the secondary engaged region is in contact matching with the secondary locking engaged part; the primary locking engaged part and the secondary locking engaged part of the clamping claw are respectively engaged with the primary engaged region and the secondary engaged region of the clamping board, so that two-stage locking is changed into independent contact; and compared with conventional matching between the same part of the clamping board and the secondary engaged structure of the clamping claw, one half of wear can be reduced, and durable times and engaging reliability of locking engagement are improved.

Problems solved by technology

[0003] After the main lock of the traditional front hood lock is opened, the hand must be inserted into the hood to open the secondary lock and open the hood. In this process, it is troublesome to complete the unlocking action at two positions. In case of emergency, such as natural, this operation It will be caught off guard, and it will dirty the hands of the operator, and cannot provide consumers with more humanized services; the traditional front cover lock clamps mostly use springs with a large return force, and at the same time realize the effect of ejecting the hood, resulting in unlocking The problem of loud sound, and because the functional parts are in a semi-naked state, there are inevitable shortcomings in terms of dustproof, waterproof and anti-theft; in addition, the part where the pull wire is connected to the traditional hood lock claw, when the hood is pressed down, the clamping plate During the process of punching the claws to complete the meshing, the ball head of the cable does not move, and there is a risk that the cable and the claws will be disengaged, resulting in the situation that the lock cannot be unlocked
