JPS5911893Y2 - Lid opening/closing structure - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a lid opening/closing structure.

Conventionally, this type of opening/closing structure was fixed with four screws on both sides of the lid, as shown in Figure 1, and when opening and closing the lid, there was a lot of work involved in removing the screws, etc., making it less efficient. was decreasing.

In addition, since screws are installed and removed in a simple manner, work space and installation space are required on both sides, which is unreasonable.

The present invention eliminates the above drawbacks and makes it easy to open and close the lid, and by providing a fixing point for the lid at the rear of the device, it eliminates wasted space when installing the device, makes effective use of the floor, and improves work efficiency. This provides a lid opening/closing structure that can be improved.

According to the present invention, a bottom plate and two side plates are integrally formed in a substantially gutter shape, and first and second receiving metal fittings are provided on the side plate parallel to the bottom plate and separated by a predetermined distance;
a bottom plate body having, at one end of the side plate, an engaging screw provided on a screw plate provided in a direction perpendicular to the side plate and the bottom plate; an upper plate, two side plates, and a rear plate are integrally formed substantially perpendicularly to each other; the first receiving metal fitting, which is provided at the lower end of the side plate of the lid body and is in a first state in which the lid body is moved a predetermined distance backward from the bottom plate body and engaged; a first guide plate having a length smaller than the separation distance of the receiving metal fitting; and a first guide plate that is substantially parallel to the first guide plate and further forward of the lid body than the first guide plate. When the cover body is positioned above and slid forward from the first state and the first guide plate falls into the separation part of the receiving metal fitting, it engages in planar engagement with the second receiving metal fitting. a second guide plate that fits together, and a position that engages with an edge of the second receiving metal fitting of the first guide plate when the lid body is further slid forward from the second state. an engaging metal fitting formed with a hook connecting part; bored in the lower part of the rear plate of the lid/body, and facing the engaging screw when in the first state; a retaining hole having a diameter larger than the head; and a screw hole portion having a slit that engages with the threaded portion of the engaging screw when in the second state; A lid opening/closing structure is obtained in which the lid is fixed to the bottom plate in the vertical direction by fastening the lid in the front-rear direction.

Next, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 2, one embodiment of the present invention includes a front plate 1, a bottom plate 3 attached to the front plate 1, and a lid 2 covering the bottom plate 3.

The bottom plate body 3 has receiving metal fittings 9 to 11 on both sides thereof, and the receiving metal fitting 9 is provided with a screw plate and fastening screws 4 at the rear thereof, and the screw holes of the lid 2 described later are inserted into the fastening screws 4. It serves as a flat plate for positioning.

Similarly, the receiving fitting 10 is a flat plate for positioning the screw hole portion of the lid to be inserted into the fastening screw 4, and has a function of connecting with a hooking joint portion 6 of the lid 2, which will be described later.

Further, the receiving metal fitting 11 has a flat plate similar to that described above, but has a function of connecting with the hook connecting portion 6 of the lid 2.

The lid 2 has a screw hole part 8 on the rear side, and this screw hole part 8 has a hole through which the head of the screw 4 passes and a thin hole (slit) through which the head of the screw does not go through. On both sides of the bottom plate body 3, engaging metal fittings having opposing 1r guide plates 7 and 5 are provided on the receiving metal fittings 9 and 10 of the bottom plate body 3.

The guide plate 7 of the lid 2 is connected to the receiving fittings 10 and 9 of the bottom plate body 3.
When facing the lid 2, the screw hole portion of the lid 2 is positioned at a position where the screw 4 provided in the bottom plate body 3 is passed.

Further, the lid 2 is positioned at a position where the screw hole 8 of the lid 2 does not allow the screw 4 provided in the bottom plate 3 to pass through when the guide portion 5 faces the receiving metal fitting 10 of the bottom plate 3.

Note that when the guide plate 7 of the lid 2 and the receiving fittings 10, 9 of the bottom plate body 3 are opposed to each other, the lid moves in the front-back direction.

When the guide plate 5 of the lid 2 and the receiving metal fitting 10 of the bottom plate body 3 face each other, the hooking joint portion 6 of the lid 2 is connected to the receiving metal fitting 1 of the bottom plate body 3.
1.10, and the lid 2 becomes unable to be removed from the bottom plate 3.

Next, referring to FIGS. 3 to 6, to explain the case of closing the lid 2, the lid 2 is moved relative to the bottom plate body 3 in the direction of the arrow 12 in FIG. are installed in the fastening screw positioning receiving fitting 9 and the hooking joint portion and fastening screw hole positioning receiving fitting 10.

Next, when the lid 2 is moved in the direction of the arrow 13 in FIG. 4, it will fall naturally, and when it is further shifted in the direction of the arrow 14 in FIG. and the screw 4 that is caught on the hook joint receiving metal fitting 11.
are simultaneously located in the screw holes 8 that can be fastened.

In this state, by tightening the screws 4 as shown by arrows 15 in FIG. 6, the lid 2 can be completely fixed to the bottom plate 3.

It is clear that opening the lid can be done in the reverse order.

As explained above, the present invention has a hook connection part and a guide part for positioning the screw hole for fastening, and also provides a place for fixing the lid with screws on the rear surface of the equipment, thereby improving work efficiency and providing flexibility in equipment installation. It has the effect of measuring
