According to the automatic lock type lock of claim 2, it is possible to combine the push type lock while making the door opening / closing operation part in common, and to provide an automatic lock type lock which is very easy to manufacture and easy to maintain. it can.

According to the automatic locking type lock of claim 3, in the event of an emergency, an emergency key can be inserted into the keyhole and unlocked, so that even if the password is forgotten, automatic locking can be easily and quickly unlocked. A lock can be provided.

It is a plane perspective view which shows one Example before the automatic locking type | mold lock of this invention. It is the front view.

Embodiments of the present invention prior to automatic locking will be described below with reference to the accompanying drawings.
In FIG. 1 and FIG. 2 showing the first embodiment of the automatic lock type lock of the present invention, 11 is an automatic lock type lock, and the automatic lock type lock 11 is an opening / closing operation of a door used for a cabinet, a locker or the like. An operating lever 12 is attached to the portion 10.
The operating lever 12 is pivotally attached to a lever rotating shaft 14 attached along the door surface 13, and contacts the door stop 15 to swing. An interlocking pin 16 is integrally attached to the operating lever 12 on the opposite side of the lever rotation shaft 14.

The door opening / closing operation unit 10 is provided with a cannula rotating shaft 17 penetrating to the back surface in a direction orthogonal to the door surface 13, and the cannula 18 is attached to the cannula rotating shaft 17, and The door stop 15 is detachable.
Further, a locking plate 19 is attached to the cannula 18 at a position opposite to the rotating shaft 17 of the cannula, and the locking plate 19 includes an engagement hole 20 having a predetermined length, and the interlocking pin 16 is connected to the interlocking pin 16. The engagement hole 20 is fitted. Accordingly, the interlocking pin 16 is rotated simultaneously with the rotation of the operating lever 12, and the locking plate 19 is also rotated by the interlocking pin 16 so that the cannula 18 is dropped and locked at the engagement position of the door stop 15.

Reference numeral 21 denotes an operation knob attached to the cannula rotating shaft 17 so as to protrude to the front surface of the door opening / closing operation unit 10.
When the operation knob 21 is turned in the opening direction, the kanuki 18 is rotated out of the engagement position of the door stop 15, and the locking plate 19 and the interlocking pin 16 are also rotated.
