Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention uses a metal base on which electrical equipment such as switches, circuit breakers, and terminal blocks are mounted. Base mounting device for electrical equipment storage box for mounting inside the electrical equipment storage box It is related to.

0002

[Conventional technology]

A metal base like the one above can be heavy if the electrical equipment storage box is large. It is heavy and difficult for workers to lift and carry to the installation location inside the box. others Install rails in the front and back direction on both sides of the bottom of the electrical equipment storage box to Support the bottom end of the base on the rail and slide it on the rail to the installation location inside the box. It is crowded. This requires fairly large guides on either side of the bottom edge of the base that slide on the rails. It is necessary to install an ID bush. Therefore, in the past, screws etc. were used at the bottom end of the base. or attach a guide bush to the base, or fold the bottom end of the base into a U-shape and A guide bush was fitted into the shaft.

0003 However, this conventional method involves attaching a guide bush to the lower end of the base and It takes a lot of work to process the lower end of the box, and the guide bush becomes loose, making it difficult to use the electrical equipment storage box. There are problems such as the guide bushing may be damaged when installing the base inside the Ta.

0004

[Problem that the idea aims to solve]

This invention solves the above-mentioned conventional problems and makes it easier to install the guide bush. It is easy to process the bottom end of the base, and it can be easily installed in the electrical equipment storage box. A base for electrical equipment storage boxes that prevents the guide bush from being damaged when installing the base. This was done to provide a base mounting device.

[0005]

[Means to solve the problem]

The above problem was solved by bending the lower end of the equipment mounting base at right angles and A square hole is made transparent in the lower surface of the , and a locking hole is made transparent in a part slightly above this square hole. It has a vertical plate part and a horizontal plate part that can fit closely to the outer surface of the above-mentioned bent part, and the lower surface thereof. A guide bush having a groove on the top surface of the guide bush, and a prismatic part formed on the upper surface of the horizontal plate part at the corner. Insert into the hole from below and engage the protrusion formed on the vertical plate part with the locking hole. A box for storing electrical equipment, characterized in that it is fixed to the lower end of the base by This can be solved by a base mounting device.

[0006]

【Example】

Next, embodiments of the present invention will be described in detail based on the drawings. In Figures 1 and 2, 1 is a base made of iron plate for installing equipment, and its lower end is A bent portion 2 is formed by bending at a right angle. As shown in FIG. 4, the lower surface of the bent portion 2 at the lower end of the base 1 includes a corner. A square hole 3 is transparently provided so that the square hole 3 A small locking hole 4 is transparently provided. Install the guide bushes on both sides of base 1. These square holes 3 and locking holes 4 are naturally located under both sides of the base 1. It is installed at the end.

[0007] 5 is a guide bushing with an L-shaped cross section made of a strong synthetic resin material such as polypropylene. It is The guide bush 5 has a vertical plate portion 6 that comes into contact with the front surface of the lower end of the base 1. , and a horizontal plate portion 7 that comes into contact with the lower surface of the bent portion 2 of the base 1. The lower surface is provided with a groove 8 for receiving the rail of an electrical equipment storage box. Furthermore, this The vertical plate portion 6 on both sides of the groove 8 is provided with two arcuate ridges 9, 9 in the vertical direction. be.

[0008] As shown in FIGS. 2 to 4, the guide bush 5 has a prismatic portion 10 on the upper surface of the horizontal plate portion 7. is made to protrude upward, and a protrusion 11 is provided on the inside of the vertical plate part 6. It is something that The distance between the prismatic portion 10 and the vertical plate portion 6 is approximately the same as the thickness of the base 1. Keep them equal.

[0009] As shown in FIG. After inserting it into the square hole 3 at the end from below, insert the protrusion 11 inside the vertical plate part 6 into the base 1. It is fixed to the lower end of the base 1 by being elastically engaged with the locking hole 4.

0010

[Effect]

With this configuration, the guide bush 5 is attached to the base 1 as described above. It can be easily attached to the base 1 by simply inserting it from the bottom into the square hole 3 at the bottom end. The bottom end of the base 1 only needs to be bent at right angles and a hole is punched. It is easy to process. Furthermore, the guide bush 5 can be moved in any direction, up, down, left or right. Movement is also regulated and there is no risk of loosening.

[0011] Then, attach the base 1 with the guide bush 5 attached to the electrical equipment storage box. When doing so, tilt the base 1 toward you as shown in FIG. Match the grooves 8 with the rails 12 on both sides of the bottom of the electrical equipment storage box. At this time, yen By using the two arcuate ridges 9, 9, engagement with the rail 12 becomes easy. If you push base 1 into the electrical equipment storage box in this state, the guide bush 5 easily slides on the rail 12 while being guided by the groove 8, and the base 1 is mounted in a predetermined position. The target position will be reached. At this time, the base 1 made of metal plate material is connected to the rail 12. No direct contact and damage is prevented. Also, there is no risk of the guide bush 5 coming loose. Therefore, the guide bush 5 may be damaged when attaching the base 1 to the electrical equipment storage box. No way.

0012

[Effect of the idea]

As explained above, this invention makes it easy to attach the guide bush to the base. In addition, the bottom end of the base is easy to process, and it can be stored inside the electrical equipment storage box. The guide bush will not be damaged when installing the base. And from metal plate material The specified mounting of the electrical equipment storage box can be carried out by sliding it on the rails without damaging the base. It can be carried to the destination. Therefore, the present invention is a conventional electrical equipment storage box of this type. It solves the problems of the base mounting device, and its practical value is extremely high. It is something.
