Description

Technical field [0001] The present invention belongs to the field of rolling gate, and in particular, the present invention relates to an operational shutter lock. Background technique [0002] Rolling gate lock (referred to as ground lock) mounted at the lower end of the rolling gate, mating under the rolling gate, with the floor fixed lock lever to realize the shutter. The structure of the ground lock, including the housing, a lock body on the housing, and a gear is provided on the lock body, and the bottom of the housing is provided with a rotating connection, and a gear and the lock hook are provided with a linkage mechanism. The key is inserted into the lock body, and the rotary key is rotated. The gear will rotate. The gear is rotated from the hook through the linkage, so that the lock hook hooks the lock bar, so that the shutter is locked, corresponding, when the key reverse rotates At the time, the gear can be rotated in reverse rotation by the linkage mechanism, so that ...

AI Technical Summary

Problems solved by technology

When the user opens the rolling gate, the key cannot be pulled out directly after inserting the key into the lock body and turning it to separate the lock hook from the lock lever, otherwise the lock hook will automatically catch the lock lever under the action of the spring, causing the roll gate to fail to open. The user needs to raise the rolling gate by one end first, so that the lock hook is completely above the lock lever, and the key cannot be pulled out until the lock hook cannot catch the lock lever even if the key is turned forward, which brings trouble to the operation.

Therefore, the lock of the existing rolling gate has the defect of troublesome operation
