Dual channel password lock

Abstract

The invention provides a double-channel coded lock which is simple in structure, reliable in transmission and convenient to install. The double-channel coded lock comprises a shell. A coded lock set, a key lock set, a switch button, a lock hook and a lock buckle are arranged on the shell. The coded lock set comprises character wheels, cams, a lock rod and a code adjusting switch; the key lock set comprises a key lock cylinder, the switch button is matched with the lock rod, the lock hook is rotationally hinged to the shell, a restoring spring is connected to the lock hook, and provides restoring force for allowing the lock hook to restore to be in locking cooperation with the lock buckle, a pushing stopping rod is arranged at one end of the lock hook, a pressing stopping rod is arranged at the other end of the lock hook, and a slant table face is arranged at the lower end of the key lock cylinder and rotates, lifts and transits to the highest point of the upper end from the lowest point of the lower end in the rotating circumference direction of the key lock cylinder; the pushing stopping rod is matched with the lock rod, moves left and right along with the lock rod and drives the lock hook to overturn left and right; the pressing stopping rod is matched with the slant table face, and rotates back and forth from the lowest point to the highest point along with the slant table face, and the slant table face is matched with the pressing stopping rod to drive the lock hook to overturn left and right.

Description

technical field [0001] The invention relates to a double-channel coded lock, in particular to a double-channel coded lock used for luggage and convenient for customs security inspection to open. Background technique [0002] In the dual-channel combination lock, since the hook and the buckle can be opened separately by the combination lock and the key lock, in terms of the reliability of the lock, the more complex the structure, the lower the reliability and the greater the probability of failure. At the same time, the production and installation It will also be more difficult. The structures of the two sets of lock groups of the existing dual-channel combination locks are all relatively complicated, especially in the transmission mechanism that drives the lock hook to open and lock, often requiring more parts to complete the more complicated transmission. However, no matter which part is jammed or damaged, the entire lock body cannot be used, so there are defects of low rel...

[0002] In the dual-channel combination lock, since the hook and the buckle can be opened separately by the combination lock and the key lock, in terms of the reliability of the lock, the more complex the structure, the lower the reliability and the greater the probability of failure. At the same time, the production and installation It will also be more difficult. The structures of the two sets of lock groups of the existing dual-channel combination locks are all relatively complicated, especially in the transmission mechanism that drives the lock hook to open and lock, often requiring more parts to complete the more complicated transmission. , no matter which part is stuck or damaged, the entire lock body will be unusable, so there are defects of low reliability and complicated installation
