Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waterproof wiring box that is internally connected when electrical wiring is performed indoors or outdoors.

[0002]

[Prior art]

 Conventionally, in this type of synthetic resin wiring box, as shown in FIG. 6, a box body 100 is attached by covering a larger lid 101, or a lid plate of the same size as the box body is interposed by a rubber packing. Then, the box body 100 is attached to the wall surface A or the like with the screw 102, and a wiring pipe is appropriately inserted into the peripheral wall or the bottom wall of the box body 100 to connect the wiring inside. .

[0003]

[Problems to be solved by the device]

 In the former of the conventional wiring boxes, since the lid that covers the box body is large, the wiring box is tilted as shown in FIG. 6 when it is mounted on the wall surface, so it is difficult to tighten the screws and the appearance is not good. It is also inconvenient when the internal wiring is connected after the wiring box is attached to the wall, because it is difficult for the lid to catch on the wall and to be detached, and when the latter lid is attached to the box body, rubber is used. When the four corners of the packing are tightened, a bulging force acts on the center of the packing, causing the center of the packing to deform in a curved shape, which may cause rainwater to enter and cause electric leakage. There is.

In this invention, the lid body is fitted inside the outer shape of the waterproof frame body attached to the box body, and the outer peripheral surfaces of the lid body and the box body are made to coincide with each other so as to be closely attached to the wall surface. It is an object of the present invention to provide a waterproof wiring box that is made easy and has improved waterproofness by interposing a waterproof frame.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the waterproof wiring box of the present invention, a waterproof frame 3 provided with waterproof means is attached to an opening 2 of a box body 1, and a lid 4 is fitted on the waterproof frame 3. The box body 1 can be attached so as to match the peripheral surface of the box body 1.

As a waterproofing means of the waterproof frame 3, an eaves-type waterproof ridge 5 is integrally formed on the upper part, and a receiving part 6 for receiving the lid 4 to be put on the outer periphery of the waterproof ridge is provided on the lower peripheral edge thereof. The lid body 4 is housed within the outer shape of the waterproof frame body 3.

Further, as a means for attaching the waterproof frame 2 to the box body 1, a groove 7 and a ridge 8 which can be fitted to each other are formed in the opening 2 of the box body 1 and the opposing surface of the waterproof frame 3. Then, securely fit the waterproof frame to the box body and secure it.

[0008]

[Action]

 According to the structure of the present invention, the ridge 8 on the lower surface of the waterproof frame 3 is fitted in the groove 7 of the opening 2 of the box body 1 and fixed with screws or the like, and then the waterproof frame 3 is covered with the lid. 4 can be covered and fixed with screws or the like, and this wiring box can be joined to the wall surface A exactly and attached with screws or the like. As in the case of conventional wiring boxes, the wiring method is to insert wiring pipes into the peripheral wall or bottom wall and connect the wiring inside.

[0009]

【Example】

 In FIGS. 1 to 5, reference numeral 1 denotes a rectangular box body having an opening 2 at the top, and a groove 7 is provided on an upper peripheral wall of the box body, and mounting cylinders 10 having screw holes 9 are provided at four inner corners. .

Reference numeral 3 denotes a quadrilateral waterproof frame that matches the box body 1, and has an eaves-shaped waterproof ridge 5 integrally formed on the upper surface thereof, and a lid body that covers the outer periphery of the waterproof ridge 5 at the lower peripheral edge thereof. The receiving portion 6 of No. 4 is provided, and the lower surface thereof is provided with the ridge 8 which fits into the groove 7 of the box body 1. The width L of the receiving portion 6 is a width corresponding to the wall thickness of the lid body 4, and when the lid body 4 is covered with the waterproof frame body 3, the lid body and the outer surface of the waterproof frame body are aligned with each other.

Further, mounting holes 11 are provided at four corners of the waterproof frame 3, screw holes 12 are provided in the middle of two sides thereof, the waterproof frame 3 is fitted into the box body 1, and screws 13 are fitted through the mounting holes 11. The mounting cylinder 10 is fixed to the screw hole 9 and the lid 4 is fixed to the screw hole 12 of the waterproof frame 3 with a screw 14. In the embodiment, the waterproof frame body and the box body are fitted and screwed together, but they may be fixed by an adhesive material.

Reference numeral 4 is a rectangular lid that matches the box body 1 and the waterproof frame 3, and the depth H thereof is slightly deeper than the height of the waterproof ridge 5 of the waterproof frame 3. Reference numeral 15 is a mounting hole. The material of the box body 1, the waterproof frame 3, and the lid 4 described above is made of synthetic resin.

With the above structure, the method of assembling the wiring box will be described. As shown in FIG. 1, the protrusions 8 on the lower surface of the waterproof frame body 3 are fitted into the recessed grooves 7 of the opening 2 of the box body 1. Then, at the four corners, the screws 13 are tightened and fixed to the mounting holes 11 and the screw holes 9 of the mounting cylinder 10, and the waterproof frame 3 is covered with the lid 4, and the mounting holes 15 and the screw holes 12 of the frame 3 are screwed. Tighten and fix.

The wiring box thus assembled is closely attached to the wall surface A and fixed with screws 16 as shown in FIG. The wiring pipe 17 is inserted into the peripheral wall and the bottom wall of the wiring box, and the wiring code 18 is inserted therein to connect the wiring inside.

[0015]

[Effect of device]

 According to this invention, the outer shape of the lid body can be accommodated within the outer shape of the waterproof frame body attached to the box body, and the outer surfaces of the lid body, the waterproof frame body, and the box body can be matched, so that the wiring box can be attached to the wall surface. This is convenient for connection work because it can be screwed tightly and securely and the lid can be easily removed when connecting internal wiring after attachment.

Since the eaves-shaped ridges of the waterproof frame are provided, even if rainwater enters from between the lid and the eaves-shaped ridges, the eaves-shaped ridges can completely prevent the intrusion into the interior, and there is no risk of electric leakage. . Furthermore, since the concave groove and the ridge are fitted together and screwed between the box body and the waterproof frame, rainwater can be completely prevented from entering.
