Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a U-shaped lock. Background Art

[0002] A U-shaped lock is a type of lock primarily used on glass doors, motorcycles, and electric scooters. Conventional U-shaped locks are classified into two types based on their locking control methods: mechanical and electronic. Mechanical locking involves using a key to lock or unlock the U-shaped lock, while electronic locking involves an electronic control system to control the locking or unlocking of the U-shaped lock.

[0003] Existing U-shaped locks are typically unlocked or locked by extending and retracting a lock tongue. The end of the lock tongue is inserted into a lock slot on a U-shaped lock rod to lock, and the lock tongue is separated from the lock slot to unlock. However, existing U-shaped locks have a complex internal structure, making them inconvenient to use. They cannot be quickly unlocked or locked, and are prone to locking failure, resulting in a poor user experience. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a U-shaped lock, in which the rotation of the lock core can drive the locking plate to slide into the locking groove of the U-shaped locking rod, and the locking plate is reset by the reset spring, so that the U-shaped locking rod can be quickly locked or unlocked.
