Lock and anti-theft door

Abstract

The invention relates to the field of intelligent locks, in particular to a lock and an anti-theft door. The lock comprises a lock body, an electric screw rod mechanism and an electric inclined tonguemechanism, wherein the electric screw rod mechanism and the electric inclined tongue mechanism are arranged on the lock body, and the electric screw rod mechanism comprises at least one spiral rod which is arranged on the first end face of the lock body in a penetrating mode and penetrates through the first end face of the lock body in a penetrating mode; and a first driving assembly for drivingthe screw rod to rotate and contract, the electric inclined tongue mechanism comprises an inclined tongue which is telescopically arranged on the first end face of the lock body in a penetrating modeand a second driving component which drives the inclined tongue to retract. The electric screw rod mechanism and the electric inclined tongue mechanism are arranged on the lock, so that intelligent opening and electric starting are achieved, the sliding mode is replaced by the mode that the screw rod rotates and retracts, so that the anti-theft performance is greatly improved, the structure is compact, the occupied space is small, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of intelligent locks, in particular to a lockset and an anti-theft door. Background technique [0002] The quality of anti-theft doors currently on the market in China is uneven. Almost all lock bodies are sliding, and the lock tongue is mainly cylindrical or square. The structure is complex, the accessories are numerous, and the failure rate is high, which can no longer meet the needs of the emerging smart locks. At the same time, it has poor defense against master keys and low anti-theft performance. [0003] And, the latch bolt is one of the important structures of the lockset. The latch bolt diffractive lockset is extended outwards, and when the lockset is closed, the latch bolt stretches inward to facilitate the lockset to close, and the latchbolt stretches out after the lockset is closed to achieve locking. [0004] The existing latch tongues basically use traditional mechanical mechanisms for manual opening, w...
