Abstract

The utility model discloses an automatic lock for the roller shutter door comprising a lock on a roller shutter and a matching key. The lock comprises a casing, lock tongues which are arranged in the casing, have a rack structure, and can be telescopic movably toward the left and the right, and a lock tongue driving mechanism which is used to drive the lock tongues to complete the telescopic action through the key plugged in a lock core. The automatic lock for the roller shutter door is characterized in that the utility model also comprises a lock tongue locking and unlocking control mechanism which is used to control the positions of the lock tongues and make the roller shutter lie in locking or unlocking state, a lock tongue position-limit mechanism under the locking state, and an automatic locking mechanism. The advantage of the automatic lock for the roller shutter door is that in the lock, the tail parts of the left and right lock tongues are formed into racks which are matched with gears clamped in the middle of the racks, and thus, the lock core can be rotated flexibly and easily under the action of the key; the lock tongues are driven to complete the telescopic motion toward the left and the right. Because of the automatic locking mechanism, when a drive sheet on the dialing head of the roller shutter pulled downwards is contacted with the earth surface, the clamping heads of the lock tongues are dialed by the dialing head in the automatic locking mechanism and separated from a lock tongue clamping groove. Then, a spring mechanism for controlling the motion of the lock tongues pushes automatically the lock tongues to complete locking the roller shutter, and furthermore, the process of locking without needing the key is convenient.
