[Detailed explanation of the idea] (Industrial application field) The present invention relates to a door locking device for a vending machine.

(Prior Art) A locking device is provided on the door of a vending machine.
This locking device is different from a simple locking device;
It is usually structured as follows. That is, a lock lever is provided on the front side of the door so that it can be put in and taken out by pulling it up, and a locking lever is provided on one end of the door, and a locking cam is provided inside the door so as to be rotatable with a key, so that the lock lever inside the door can be locked. There is. On the other hand, on the back side of the door, a lock slide plate is installed that is connected to the lock lever via a link mechanism and moves up and down as the lock lever is inserted and removed. A door lock arm having a notch that can be engaged with the edge is fixed so that the notch of the door lock arm also engages the edge of the hole in the lock slide plate when the door is closed, thereby locking the door. For reference, FIG. 7 shows the door lock arm 2, the lock lever 10, and the lock 40 for key insertion.

This type of locking device is, for example,
This is shown in Publication No. 140661.

(Problems to be solved by the invention) By the way, vending machines require various inspections at the time of initial setup and after troubleshooting. As shown in Figure 7, this inspection involves viewing and operating various display boards and operation buttons on the front side of the door 1 with the door 1 open, as well as operating various devices on the back side of the door 1. This must be done while also checking the operating status of the product delivery machine on the vending machine itself.

In this way, inspection work that requires alternately viewing and operating the front and back sides of the door 1 is extremely troublesome, and recently remote control units have been provided as a means to facilitate this work. . This remote control unit 3 is electrically connected to equipment on the back side of the door 1, and can operate the back side of the door 1 from the front side.

However, since this type of inspection was conducted with door 1 left ajar without any locking, door 1 closed with a slight force, and the remote control was placed between door 1 and the vending machine body. There were many cases where the unit 3 cord was pinched. For this reason,
The cord of the remote control unit 3 had the disadvantage of causing breakage or shorting.

The present invention aims to eliminate these drawbacks, and is a vending machine door locking device that uses the existing door lock arm to lock the door when it is closed and to lock the door when it is slightly open. The purpose is to provide

(Means for Solving the Problems) The present invention includes a lock lever provided on the door of a vending machine with one end pivotably supported so as to be able to be put in and taken out from the front side of the door, and a lock lever provided in the door so as to be rotatable with a key. a locking cam that locks the lock lever when it is inside the door; and a lock slide that is connected to the lock lever via a link mechanism and is provided on the back side of the door so as to move up and down when the lock lever is inserted or removed. In a vending machine equipped with a door lock device comprising a plate and a door lock arm having a notch that can be engaged with an edge of a hole provided in the lock slide plate fixed to the main body of the vending machine, the door The door locking mechanism is characterized in that the door locking mechanism is provided on the back side of the door locking arm to lock the door at a predetermined opening angle by engaging with the notch of the door lock arm.
