Abstract

The invention provides a double-backup unlocked U-shaped lock. The double-backup unlocked U-shaped lock is mainly characterized in that a lock cylinder hole of a lock body (16) is provided with an inner ring (18), a rotary lock tongue (11) enters from the left end of a lock body (36), a lock cylinder (13) and a sleeve core (14) enter from the other end of the lock body (36), and the rotary lock tongue (11) and the lock cylinder (13) are connected through a connection pin (12); a lock head combination piece is a double-backup unlocked lock head, and double-backup unlocking can be realized through keys with two different types of tooth patterns; the lower portion of the front end of the lock body (16) is provided with a cut, an installation hole of a lock body screw (9) is formed, the lock body screw (9) enters from a lock hole (10) and completely fixes the lock body (16) and the lock head combination piece in a combined lock sleeve (17), in a locked state, a lock hook (1) seals the lockhole (10), and the lock head combination piece cannot be detached. The lock body screw (9) can also limit the rotation angle of the rotary lock tongue (11), and after the lock is unlocked, the lock head combination piece can be taken out by detaching the lock body screw (9) to have a key made to fit a lock again.

Description

technical field [0001] The double-backup opening U-shaped lock belongs to the manufacturing technology of locks, and in particular relates to a U-shaped lock that has only one lock head and one lock hole and can be opened by double backups. Background technique [0002] The application of U-shaped locks is quite common. Most of the two-wheeled electric vehicles and three-wheeled electric vehicles use U-shaped locks. However, the existing U-shaped locks still have many defects. Disassemble and re-allocate the key, especially the double-backup unlocking is not possible. It is often seen that the electric car has a key but cannot open the U-shaped lock, and cannot walk. See patent application number; 201710803298.3, double-backup opening lock. Double backup opening U-shaped lock means that the U-shaped lock has only one lock head and one lock hole, and there are two independent unlocking surfaces (two lock surfaces) in the lock hole, which can be unlocked with two keys with dif...
