Since the above-mentioned conventional home delivery box is installed in a building such as an entrance of an apartment house, there is no need to consider rainwater infiltration, and there is no problem even if a door provided with an electric lock is provided for each accommodation section.
However, if a large home delivery box is newly installed, it may be installed outdoors if there is no space indoors. In a relatively large-scale factory or the like, a delivery box having a delivery box near the factory entrance is more efficient for delivery, which is convenient for a delivery company. In this case, since it is installed outdoors, it is necessary to take measures against rainwater, and it is preferable to close the entire delivery box with one door and lock it, rather than providing a door for each of the storage units in the baggage, because the cost can be reduced, which is preferable.

On the other hand, as a cabinet installed outdoors, there has been a cabinet used for a cubicle housing electric equipment. In this cabinet, a lock such as a cylinder lock was provided on a handle provided on the door, and the cabinet could be locked.
However, since a key is required to open and close the lock, it is not suitable for a home delivery box as it is, and it has been necessary to change to an electric lock which can be unlocked with a personal identification number without carrying a key. In such a case, rainwater easily penetrates into the handle portion, which is not suitable as a place for assembling the electric lock, and the handle provided with the lock itself has few options and the degree of freedom in design is limited.

  In view of such problems, an object of the present invention is to provide a cabinet door lock structure that can be installed outdoors even with an electric lock.

A cabinet door lock structure in which a closed door is held by the rod being locked to the cabinet body. The cabinet body is locked to the tip of the elongated chain rod to prevent the chain rod from retracting. The locking device for the chain rod is provided, and the portion where the locking device of the chain bar is locked is a horizontal portion formed by bending the chain bar.
According to this configuration, since the locking device locks the horizontal portion formed on the chain-shaped bar, it is possible to prevent the chain-shaped bar from retracting with a simple structure and lock the door. Further, since the lock device is installed in the cabinet body, there is no need to provide a lock function to the handle, and the options of the handle and the door can be widened, which is preferable in design.

According to a second aspect of the present invention, in the configuration according to the first aspect, the horizontal portion of the chain-shaped bar is formed by bending the chain-shaped bar into an L-shape in the interior direction of the cabinet main body. It is characterized in that it is locked to a horizontal part in the inside of the.
According to this configuration, the locking rod is formed by bending the chain rod in the interior direction of the cabinet main body, so that the entire lock device can be arranged inside the cabinet main body. This can be prevented. Therefore, even if the lock device is constituted by an electric lock, the life can be extended.

  According to the present invention, since the locking device locks the horizontal portion formed on the chain-shaped bar, it is possible to prevent the chain-shaped bar from contracting with a simple structure and lock the door. In addition, since the lock device is installed in the cabinet main body, there is no need to provide a lock function on the handle, the options of the handle and the door can be widened, and the design is preferable.

The door lock structure of the present invention is applied to the first cabinet 2, and a lock device 5 including an electric lock for locking the door 2b is assembled. Hereinafter, the first cabinet 2 provided with the lock device 5 will be specifically described.

An open front surface of the main body 2a is provided with a frame (front frame) 21 formed by bending a steel plate continuously formed from a peripheral side plate and a top plate, and the inside of the front frame 21 is opened. The double door 2b is configured to cover the front surface of the main body 2a including the front frame 21 and close the front opening P. The door 2b is formed bilaterally symmetrically, and handles 22 are provided near the center of the main body 2a on the open end side. Opening and closing operations are enabled by the operation of the handle 22. However, it is configured to have an overlapping portion so that a gap is not generated at the center of the front opening P when the door is closed.
On the back surface of the door 2b, a chain rod 23 that expands and contracts in the vertical direction by rotating the handle 22 is assembled, and when extended, the upper and lower ends of the chain rod 23 are locked to the main body 2a, The lock is released when retracted.

  Specifically, the chain rod 23 is configured by a pair of rod rods 23a and 23b as shown in FIG.
