Description

Alarm U-shaped lock

Technical Field

The utility model relates to the technical field of locks, in particular to an alarm U-shaped lock.

Background

The lock means a closed tool, which includes a lock, a key and its accessories, and is generally interpreted as a "sealing device which can be opened by a key", the conventional lock has only a pure mechanical structure, and is locked and unlocked by a mechanical structure, but the mechanical structure of a part of the lock has low strength, when an external force is applied to the outside of the lock to unlock the lock by a violent force, the lock may be disassembled, and the lock with the pure mechanical structure does not have an alarm function, and the lock is not found even when the lock is unlocked by the violent force by the external force, so the safety of the conventional mechanical lock is lacking.

For example, CN204754505U discloses a high anti-theft U-shaped lock, including a U-shaped lock rod and a lock body, wherein the lock body comprises a lock head component, a lock gate and a lock body shell, the lock head component and the lock gate are arranged in the lock body shell, two ends of the U-shaped lock rod are mortise lock ends, the lock body shell is clearance fit with a jack with the mortise lock ends, any point in the section of the U-shaped lock rod is taken as a center, the distance from at least part to the center on the section profile is unequal from the rest part to the center, and the shape of the jack is the same as the shape of the section profile of the U-shaped lock rod. Because the cross section of the U-shaped lock rod and the jack are not round, when one end of the U-shaped lock rod is broken by the theft molecule, the U-shaped lock rod still cannot rotate around the other end to open the lock, and the lock can be opened only after both ends are sawed at the same time, although the high anti-theft U-shaped lock increases the unlocking difficulty, improves the anti-theft performance, but still improves the anti-theft performance in a mechanical structure mode, and as mentioned above, the U-shaped lock rod can still be unlocked after being sawed by force, namely, the lock can be unlocked and not found under the condition of forced unlocking by external force, and the safety is still lacking.
