Of the cylinder lock 4, the link 5 configured on the back surface of the door 2 and synchronized with the rotation of the cylinder lock 4, the link pin 5 a configured on the link 5, and the link pin 5 a configured on the back surface of the right end portion of the door 2. A slide bar 6 that moves upward by rotation, an opening 6b that is formed in a short shape on the slide bar 6, and a convex portion that is formed on the slide bar 6 and that contacts the link pin 5a and transmits the upward rotation. 6c, an engaging portion 7 that is configured at the right end portion of the front surface of the main body 1 and is joined to the slide bar 6, and a slide bar 6 that is formed in the engaging portion 7 and contacts the slide bar 6 moves upward. Attached to the inclined claw portion 7b and the slide bar 6, Composed of the lock pin 8 in contact with Hasutsume portion 7b.

  The operation of the door lock device configured as described above will be described below.

  When closing the door 2, the key 3 is removed at the locking position. By closing the door 2 in this state, the lock pin 8 attached to the slide bar 6 comes into contact with the inclined surface of the inclined claw portion 7b, and the slide bar 6 moves upward. Then, when the door 2 is closed to the closed position, the lock pin 8 falls into the groove of the engaging portion 7 so that the lock pin 8 and the inclined claw portion 7b can be engaged.

  Next, when the door 2 is opened, the key 3 is inserted into the cylinder lock 4 and rotated, whereby the link 5 is rotated synchronously, the link pin 5a raises the convex portion 6c, and the slide bar 6 Moves upward. When the door 2 is opened in this state, the engagement between the lock pin 8 and the inclined claw portion 7b is released, and the door 2 rotates forward.

  As described above, in the present embodiment, the door 2 can be locked without using the key 3 when the door 2 is closed.

(Embodiment 2)
FIG. 2 is a side view of a door lock device according to Embodiment 2 of the present invention.

  In FIG. 2, a projecting portion 7 c formed at the engaging portion 7 and at the tip of the inclined claw portion 7 b and an inclined groove portion 7 d configured as a groove portion of the engaging portion 7 are configured.

  In the present embodiment, the door lock device according to the first embodiment is further provided with a protrusion 7c and an inclined groove 7d.

  The operation of the door lock device configured as described above will be described below.

  When the door 2 is closed, when the door 2 is closed, the lock pin 8 comes into contact with the inclined surface of the inclined claw portion 7b of the engaging portion 7 and the slide bar 6 moves upward. By providing the protrusion 7c at the tip of the portion 7b and providing the inclined groove 7d downward from the protrusion 7c, the lock pin 8 is guided and can be smoothly dropped.

(Embodiment 3)
FIG. 3 is a perspective view of a door lock device according to Embodiment 3 of the present invention.

  In FIG. 3, the long hole portion 7 e formed in the engaging portion 7, the screw A 9 for fixing the engaging portion 7 to the main body 1 of the vending machine, and the long hole portion 7 e of the engaging portion 7 are arranged. A screw B10 fixed to the main body 1 of the vending machine is configured.

  In the present embodiment, the door lock device according to the first embodiment is further provided with a long hole portion 7e, a screw A9, and a screw B10.

  The operation of the door lock device configured as described above will be described below.

  Although the engaging portion 7 is fixed to the main body 1 of the vending machine by two screws A9, the lock position varies when the main body 1 and the door 2 are assembled. When this position variation occurs, adjustment is made by loosening the screw A9 and sliding the engaging portion 7 in the horizontal direction. At this time, the two screws A9 are loosened to try to slide the engaging portion 7 in the horizontal direction, but it also moves in the vertical direction, and a jig is required to adjust the engaging portion 7 to the correct position. Met. Therefore, it is possible to easily adjust the position of the engaging portion 7 without using a jig by providing a long hole portion 7e in the engaging portion 7 and suppressing the rattling in the vertical direction with several screws B10. It is possible to easily cope with readjustment in the market.

  Further, in the present embodiment, the vertical position restriction is performed with the screw B10. However, the vertical position restriction may be performed by increasing the number of screws A9.

(Embodiment 4)
FIG. 4 is a perspective view of a door lock device according to Embodiment 4 of the present invention.

  In FIG. 4, a spring 11 for connecting the lower part of the slide bar 6 and the frame of the door 2 and pulling the slide bar 6 downward is configured.

  The operation of the door lock device configured as described above will be described below.

  When the door 2 is closed, the lock pin 8 falls into the groove of the engaging portion 7 so that the lock pin 8 and the inclined claw portion 7b can be engaged, but the slide bar 6 falls off. This is due to the weight of the slide bar 6 itself. If the weight of the slide bar 6 is light in size and material, it may be difficult to drop by its own weight. Therefore, the lower part of the slide bar 6 and the frame of the door 2 are connected by a spring 11 so that the slide bar 6 is always pulled downward, so that the slide bar 6 can be reliably dropped even when the weight of the slide bar 6 is light. It becomes possible.

(Embodiment 5)
FIG. 5 is a perspective view of a door lock device according to Embodiment 5 of the present invention.

  In FIG. 5, a door protector 12 is configured so that the slide bar 6 and the lock pin 8 cannot be touched from the gap between the door 2 and the main body 1 with the door 2 closed.

  In the present embodiment, a door protector 12 is further provided on the door lock device according to the first embodiment.

  The operation of the door lock device configured as described above will be described below.

  When the door 2 is closed, the door may be unlocked from the gap between the door 2 and the main body 1 by a wire or the like. Therefore, by configuring the door protector 12 on the frame of the door 2, the door protector 12 can enter between the engaging portion 7 and the main body 1 when the door 2 is closed, and the door is locked from the outside. It becomes possible to prevent the release.

  Moreover, in this Embodiment, although the door protector 12 is comprised over the frame full length of the door 2, it is also possible to comprise only in two places of the engaging part 7 instead of full length.

  As described above, since the door lock device according to the present invention can lock the door 2 without using the key 3, the door lock device is required to have a door lock function as well as a vending machine. Applicable to products equipped with
