Description

Gear lock with lock tongue and latch bolt not linked

Technical Field

The invention relates to the technical field of gear locks, in particular to a gear lock with a lock tongue and an oblique lock tongue not linked.

Background

At present, most door locks on the market are gear locks, the structures in the locks are complex, and the clutch function is usually realized by matching a plurality of gears with other parts; the complex clutch structure also leads the lock tongue and the latch bolt to be only synchronously recovered, thus easily causing the excessive unlocking force and the breakage of the key in the unlocking process; the structure makes the lock tongue difficult to recover in place, particularly about 3mm at the maximum thickness, and the recovery of the lock tongue is pulled by the spring force. The lock has the advantages that the lock is also provided with a part of two-gear locks in the market, the structure of the two-gear locks is more complex, a plurality of clamping points are arranged in the using process of the two-gear locks, once the lock tongue stops at the clamping points and is clamped, the lock cylinder cannot be opened, and only the two-gear locks can be opened by force, so that the lockset is damaged.

Clutch mechanism all uses basically in the gear lock on the market, and current application number CN108757854A discloses a lock body clutch mechanism, realizes the separation and reunion function through stirring of the boss on the separation and reunion shifting block to the slider, and its realization process needs the separation and reunion shifting block to realize in the independent operation of perpendicular and 2 horizontal dimensions and the motion cooperation of slider on single dimension plane: firstly, the clutch shifting block is required to be pulled in the vertical direction, so that the clamping table at the lower end of the clutch shifting block is separated from the bayonet; then the clutch shifting block is rotated, so that the sliding block is shifted to be at the first position or the second position, and then the clamping table is required to be clamped in the clamping opening again. Because the realization of this separation and reunion function, two notches through the card platform on the separation and reunion shifting post and separation and reunion through-hole lower part are to two position location of slider, realize the separation and reunion function, and its flexibility is not high, and the operation is complicated, appears out of gear's the condition moreover easily.

Aiming at the defects of the existing gear lock in the market, a clutch mechanism is developed for solving the problem of knocking and waiting 1. the lock clutch mechanism has simple structure, stability and high efficiency; 2, the use of the clutch structure can optimize parts in the lockset, the recovery of the lock tongue and the latch bolt can be independently controlled, and the occurrence that a key cannot be unlocked due to the clamping stagnation of an internal structure is reduced; and 3, reducing the torsion of the lock cylinder and preventing the key from being broken.
