Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching an opening/closing lid to a case of an electrical device or the like.

Conventionally, the opening/closing structure of the case was used, for example, as a housing case for a ceiling-suspended monitor TV camera.
As shown in Fig. 1, there was one in which two opening/closing lids 2 were attached that opened in the shape of wings from both side plates (one side plate 1 is shown in Fig. 1) to the center of the bottom plate. However, in this structure, the opening/closing lid 2 is screwed to the front and rear frames in the closed state using fixing fittings 3 having an L-shaped cross section, so opening and closing the opening/closing lid 2 during maintenance and inspection is not a hassle. There was once a time. In addition, this opening/closing lid 2 is weak against force from the sides, and the front and rear frames (side plates)
There were problems such as gaps easily forming between the two. 4 is a screw for fixing the opening/closing lid, 5 is a screw for attaching a fixing fitting to the side plate, and 6 is a hole for hanging from the ceiling.

The present invention was developed in view of the above points, and by configuring both ends and the lower end of the opening/closing lid to fit into the front and rear frames without using screws, the opening/closing lid can be easily opened and closed. Furthermore, the present invention aims to provide a case opening/closing structure that can provide sufficient strength.

Hereinafter, the configuration of the present invention will be explained based on FIGS. 2 and 3. 7 is a case for accommodating equipment such as a monitor television camera, and this case 7 has a frame consisting of a top plate 8, a left side plate (rear frame) 10, and a right side plate (front frame) 11.
It is formed by attaching an opening/closing lid 12 serving as the front plate and half of the bottom plate, and an opening/closing lid 13 serving as the rear plate and the other half of the bottom plate. Opening/closing lid 1
A shaft 14 is protruded from the upper side of the side plates 2 and 13, and a bearing 15 for inserting and pivotally supporting the shaft 14 is provided at the upper part of the side plates 11 and 10. In addition, the opening/closing lid 1
2 and 13, and the opening/closing lids 12 and 13.
Engagement protrusions 16 and 17 are provided on the outside of the tips of the bottom surface, and the engagement protrusions 1 are provided on the left side plate 10 and the right side plate 11 at positions corresponding to the engagement protrusions 16 and 17.
Engagement recesses 18, 20 for fitting 6, 17 together
is provided. That is, the engaging protrusions 1 are provided on the inside of both ends of the side surfaces of the opening/closing lids 12 and 13 and on the outside of the tips of the bottom surfaces.
6 and 17 are provided, and correspondingly both side plates 1
Engagement recesses 18 and 20 protruding inward are provided at the center of the side and bottom surfaces of 0 and 11. Reference numeral 21 represents a ceiling mount, and 22 represents a ceiling mount hole provided in the top plate.

In the case opening/closing structure configured as described above, the opening/closing lid 1 is attached to the bearing 15 of both side plates 11, 10.
By fitting the shafts 14 of 2 and 13 together, the opening/closing lid 12,
13, the engagement protrusions 16 and 17 are fitted into the engagement recesses 18 and 20. Both the frame and the opening/closing lids 12 and 13 are integrally molded from synthetic resin, and when fitting the bearing 15 of the shaft 14 and fitting the engaging protrusion 17 into the engaging recess 20, the opening/closing lid must be slightly bent. do.

Since the present invention is constructed as described above, the opening/closing lid can be easily opened and closed without using screws or L-shaped fixing fittings, and since both side plates and the sides of the opening/closing lid are engaged, This has the practical effect that sufficient strength is obtained and no gap is created between the two.
