In FIGS. 5, 6 and 7, reference numeral 1 denotes a vending machine main body, 2 denotes a door pivotally supported by the main body 1, and 3 denotes an engagement hole 4.
And a latch having a vertically long guide hole 5, a support plate 6 for locking the latch 3 to the door 2, and a support plate 6 through the guide hole 5 allowing the latch 3 to slide vertically. The fixed pin 8 is a receiving bracket having an upper locking groove 9 provided at a position facing the engaging hole 4 of the main body 1, and 10 is the door 2.
A handle 11 provided on the front surface of the handle 3 for sliding the latch 3 is a connecting portion for converting the rotational movement of the handle 10 into a vertical movement of the latch 3.

[0006] The operation of the locking device for a vending machine configured as described above will be described below.

First, when the door 2 is open, the handle 1
0 is rotated to one side, and the rotational motion is converted into a vertical motion by the connecting portion 11, and the latch 3 is slid upward to close the door 2. At that time, the receiving fitting 8 enters the engaging hole 4.
Then, the handle 10 is rotated in the opposite direction, the latch 3 is slid downward, the engagement hole 4 is locked in the locking groove 9, and the door 2 is locked.

[0008]

However, in the above-mentioned conventional structure, the engaging hole 4 is engaged with the engaging groove 9 only in one direction, and the vending machine main body 1 and the door 2 are not connected to each other. Since there is a gap between them, there is a drawback that a rod or the like is inserted into the engaging hole 4 and lifted up from the gap, the connecting portion 11 is broken, the latch 3 is removed from the receiving bracket 8, and the door 2 can be opened.

An object of the present invention is to solve the conventional problem and to prevent the door of a vending machine from being opened.

[0010]

In order to achieve this object, a locking device for a vending machine according to the present invention includes a door pivotally supported by a vending machine main body and a door slidably engaged with the door in a vertical direction. And a handle with a connecting part interposed between the latch provided on the front part of the door and the latch provided on the front surface of the door, and opposed to the latch of the latch. A receiving metal fitting A having an engaging groove provided at a position, and a flange-shaped flat piece provided in the receiving metal fitting A having a height and a width equal to or greater than the height and the width of the engaging hole, respectively. And a face plate.
