Description

Lock structure

technical field

The invention relates to a lock seat, in particular to a lock seat structure of a fireproof door lock.

Background technique

The existing conventional sky-and-earth fire-proof door lock mainly controls the unlocking and locking action of the sky-and-earth bolt through the lock seat. However, the sky-and-earth fire-proof door lock must be installed from the right side door due to space design changes or other safety considerations. When installing to the left door or changing from the left door to the right door, since the lock seat of the existing conventional fireproof door lock can only be unlocked in a single rotation direction, once the installation position is reversed, the unlocking rotation direction will be changed. It will also change accordingly, which will cause trouble and inconvenience to the user in operation. In order to solve the above-mentioned problems, the general users mostly repurchase suitable lock bases, and this method will increase the cost of replacing the lock bases.
