Description

The present invention relates to a locking structure of a display device storage box .

  Conventionally, the structure of electrical equipment storage boxes used for distribution boards, switchboards, etc., is to install side plates, doors, etc. on the opening frame part of the side plate of the frame assembled into a square frame shape, and to open and close the door A structure in which the handle is exposed and attached to the outside of the door is widely and generally employed (for example, Patent Document 1).

  However, when the electrical equipment storage box is used as a display device such as an electronic signboard that has been rapidly spreading in recent years and includes a display unit for displaying an electronic advertisement on the door of the housing, it is disposed adjacent to the display unit. There was a problem that the presence of the handle to be handled was not aesthetically desirable. In addition, since the handle adjacent to the display unit that performs the advertising function and is eye-catching is unavoidably visible, there is also a problem that mischief tends to be symmetric.

  In addition, when providing a large display portion of a size that can be viewed from a distance, it is necessary to increase the size of the electrical device storage box. With the increase in size of the housing, for example, it is assumed that the locking part is provided at two places, the upper and lower parts of the door, and the door is locked by a plurality of locking parts, but the locking parts are provided at several places. However, there is a problem that accidents such as forgetting to lock in any of the locking portions are likely to occur.
