Screw the screw that penetrates the bottom plate of the lock case
Only a few screws need to be tightened,
The operation is simple and quick, and the lock
The case and pedestal are fastened together, so that there is no looseness
Can be loosened because it is not simply screwing on the door
Even then, re-tightening becomes possible.

[0043] In addition, the present invention, it becomes possible locked in a state where the closing locked doors, the dead bolt which is disposed at the rear end of the push cylinder lock, the engagement groove of the recessed into the guide tube in a push cylinder lock It can be freely disengaged,
Thereby, locking and unlocking can be performed. In the unlocked state, the locking and unlocking of the door can be freely performed by the push operation of the push cylinder lock. However, when the lock is locked, the push operation of the push cylinder lock is prevented, thereby unlocking the engagement of the door. Not only can be prevented, but also the push cylinder lock cannot be pushed, so that the user can confirm the locked state and the locked state of the door. Accordingly, as in the case where the lock handle device and the cylinder lock are separately mounted, the engagement lock is released in the locked state, and the lock is unlocked in the engagement lock state and the door is forcibly opened to thereby obtain the dead bolt. An unreasonable external force in the door opening direction acts on the engaging member and the engaging member, or the latch and the receiving seat, thereby preventing the member from being damaged.

Further, since there is no need to provide an engaging member for engaging and disengaging the dead bolt on the cabinet side, it is sufficient to consider only the positional relationship between the latch and the hook, and the mounting seat and striker on the cabinet side. Therefore, the door can be easily mounted, and the door can be designed more freely than when the lock handle device and the cylinder lock are separately mounted.
