Kind Code:
A
Abstract:

To provide a simply structured practical locking device for a crime prevention buzzer at a low cost which is easy to install, and to set or changeover for the time of use or nonuse.

The locking device includes a mounting base mounted inside a door body, and an alarm device. The alarm device has an outer shell having the size that stops a double sliding movement of an inner door body by abutting a double sliding wall of the inner door body in a mounted state on the mounting base. The inner door body presses and moves an activation body by the double sliding movement of the inner or an outer door body so that an alarm sound may go off. After that, when an opening force in a double sliding direction is given further, the alarm device receives the force in the double sliding direction for stopping and locking operation, in a state that a part of the inner door body is spatially overlapped with a part of the mounting base. When an intruder opens the door body making the inner door body hit the activation body, and further conducts the opening operation, the opening movement is hindered by the alarm device itself and the crime prevention is carried out.
