When the opening of the case 1 is opened, the main body cover 10 is pulled to the front side of the case 1 by using the pins 13 as rotational fulcrums in the initial stage and, then, housed in or out of the case 1 by putting the cover 10 on the bottom plate of the case 1 by sliding the pins 13 along the grooves 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing structure for a base station communication device or the like, and more particularly, to a device housing structure having a sliding lid for closing / opening a housing.

[0002]

2. Description of the Related Art Conventionally, as a device housing structure, there is a communication device housing described in, for example, Japanese Patent Application Laid-Open No. 7-307852. In this case, the cover of the lid member is attached to the opening of the case of the housing body so that one side can be hinged and one side can be opened and closed, and the open / close end of the cover is closed by a fastening member set with a bolt and a rotary nut during closing. I can lock it.

[0003]

[Problems to be solved by the invention]. By the way, the following problems to be solved remain in the conventional device housing structure including the communication device housing of the above-mentioned publication cited as the conventional example.

[0004] The main body cover is opened during maintenance work and the like, but this main body cover is attached to the main body case. Therefore, in the case where other devices arranged in the vicinity are also inspected at the same time, the opened main body cover hinders the operation of the other devices. In particular, when working in a narrow place, the open body cover is often tripped over, which may cause unexpected harm to persons and equipment.

[0005] Further, even in the case of a structure in which the opened main body cover can be completely removed from the main body case, it is necessary to secure a sufficiently large work space required for removal, and there is an inconvenience in dealing with a narrow work place.

Accordingly, an object of the present invention is particularly suitable for a housing structure for a base station communication device, and the functionality of a cover opening / closing structure is provided so that a cover of an opened cover member does not hinder maintenance work and the like. It is an object of the present invention to provide a device housing structure that improves the size and convenience of use.

[0007]

According to the device housing structure of the present invention, a box-shaped main body case for storing electronic components has an opening on almost one entire surface, a case side plate on both sides thereof, and a case bottom plate. In opening and closing the opening of the main body case with the main body cover of the lid member, a pair of parallel guide long grooves extending in the front-rear depth direction are provided on the case side plates on both sides, and a slide pin engaged with this guide long groove is provided. When the opening of the main body case is opened by providing protrusions on both side end surfaces of the main body cover, at the time of initial movement, the main body cover is pulled out with the slide pin as a pivot point, and the slide pin is pulled out. The main body cover is slidably moved by the guide of the guide long groove so that the main body cover can be stored so as to overlap the case bottom plate of the main body case.

In this case, the main body cover can be stored outside the case bottom plate, or can be stored inside the double bottom space when the case bottom plate has a double bottom structure.

When the guide slot is provided near the lower end of the case side plate in the vertical direction, a pair of left and right slide pins project from both sides of the lower end of the main body cover corresponding to the position. With the slide pin as a hinge pin, the main body cover can be pulled down from the upper end to a horizontal position of approximately 90 ° in front of the main body cover, and a one-sided double-sided opening structure can be opened.

Further, if an opening / closing knob for pull-out operation is provided at the upper end of the main body cover, the operation is convenient, and the opening / closing knob can have a locking or unlocking function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an apparatus housing structure according to the present invention will be described below in detail with reference to FIGS.

FIG. 1 is a perspective view showing the entire structure. It has a main body case 1 for storing various electronic components such as a communication circuit board and wiring, and the front open end of the main body case 1 is closed / opened by a main body cover 10 of a lid member.

The case side plates 2 on both sides as viewed from the front open end of the main body case 1 are formed with guide elongated grooves 3 having an L-shaped cross section along the lower end in the front-rear depth direction. Also,
As shown in the enlarged side view of FIG. 1 and in FIG. 2, an L-shaped cross section for assisting initial movement when opening and closing the main body cover 10 and for guiding smoothly at a position immediately below the front end of the guide elongated groove 3. Are fixed.

On the other hand, the main body cover 10 has a rectangular shape whose main plate 11 has an area enough to close the front opening end of the main body case 1. A folded side plate 12 is provided along the four sides of the main plate 11 in a box shape. is there. In the folded side plates 12 on both sides of the main plate 11, a pair of convex slide pins 13 are provided at each lower end thereof so as to protrude left and right. Slide pin 1
The guide 3 is engaged with the guide groove 3 provided in the case side plate 2 and guided to guide the opening and closing operation of the main body cover 10. Further, near the upper end of the main plate 11, a pair of opening / closing knobs 14 are provided on both left and right sides so as to protrude in a convex shape.

Next, with the above configuration, when performing maintenance work and the like, when the main body cover 10 is opened and opened inside from the state closed at the front opening end of the main body case 1, the operator needs the main plate 11 of the main body cover 10. Has a pair of opening / closing knobs 14 and pulls it forward. By this knob operation, the upper end of the main plate 11 is first pulled out toward the front.

As shown by the imaginary line in FIG. 1, the main plate 11 is pulled out by the pull-out operation of the main body cover 10 by the knob operation.
Is pivoted about the slide pins 13 on both sides at the lower end thereof, and is pulled down to a horizontal position substantially 90 ° before.

With the main plate 11 of the main body cover 10 facing forward,
At the stage where it is pulled down to the horizontal position of 0 °, the main plate 11
Into the body case 1.
At this time, the slide pins 13 on both sides are guided by the slide long grooves 3 on the main body case 1 side and slide toward the back of the case side plate 11.

When the slide pins 13 slide, the main plate 11 is housed in a substantially horizontal position so as to overlap the outside of the bottom plate in the main body case 1. The operation of the main plate 11 so far is supported from below by the guide auxiliary piece 4 provided on the main body case 1 side from the initial stage, and smoothly assists the operation from pulling down to pushing.

In this manner, the main body cover 10 is stored without occupying a useless storage space so as to overlap with the outside of the bottom plate of the main body case 1 with almost one touch. A required operation is performed by opening the inside of the main body case 1. During that time, the main body cover 10 does not hinder any work. After the work is completed, reverse the above-mentioned procedure and proceed to the body cover 1
0, the main body case 1 is closed.

The opening / closing knob 14 provided on the main plate 11 of the main body cover 10 may be of a push-pull structure having an opening / closing lock function, or of a variety of structures such as a screw-in type.

Also, it has been described that the main body cover 10 is stored outside the bottom plate of the main body case 1. However, if a double bottom is formed inside the bottom plate, the double bottom space allows the main body case 1 to be accommodated in the main body case 1. It will be readily understood that a storage structure is also possible.
