Description

[Detailed description of the invention] This invention mainly relates to a mounting bracket for attaching electrical equipment, etc. to a suitable support.The purpose of this invention is to have an extremely simple structure that can be applied to various supports of different shapes. The present invention provides a mounting bracket that can be easily installed.

An embodiment of this invention will be described below with reference to the drawings.

Reference numeral 1 indicates a main body having a U-shaped portion 1a with the lower end side of a substantially T-shaped plate bent into a U-shape, and a wide portion 1b on the other side; 2 indicates the U-shaped portion 1a; Two screw holes are arranged in the main body 1 in a direction perpendicular to the groove, 3 are holes drilled at several intervals in the center and wide part 1b of the main body 1, and 4 are long holes made by bending the plate approximately at right angles. A presser metal fitting having a piece 4a and a short piece 4b formed therein; 5 a bent edge formed by bending each outer end of the long piece 4a and short piece 4b of the presser metal fitting 4 into an acute chevron shape; 6 a bent edge of these long pieces 4;
Holes 7 drilled in a and short pieces 4b are inserted into one hole 6 of this presser fitting 4 and screwed into each screw hole 2 of the main body 1.
A thumbscrew 8 is a washer that is attached to the outer periphery of the thumbscrew 7.

This invention has the above structure, and in order to attach the short circuit current passage indicator 9 to a support in a distribution tower using this invention, for example, as shown in FIG. The upper surface of the main body 1 of this invention is brought into contact with the lower end surface of a bracket attachment fitting 12 in the form of a horizontally narrow plate to which is fixed, and the end surface of the U-shaped portion 1a is brought into contact with the back surface of the bracket attachment fitting 12. Then, the bent edge 5 on the long piece 4a side of the presser metal fitting 4 is locked to the upper edge of the bracket mounting fitting 12, the long piece 4a is overlapped on the front of the bracket mounting fitting 12, and the bent edge 5 on the short piece 4b side is fixed. is brought into contact with the top surface of the main body 1, and the tip of the thumbscrew 7 inserted through the hole 6 of the short piece 4b of the presser metal fitting 4 is screwed into one of the screw holes 2 near the U-shaped portion 1a of the main body 1,
By tightening the thumbscrew 7, the device is firmly fixed to the bracket fitting 12. Then, the pedestal part 13 of the short circuit current passage indicator 9 is placed on the wide part 1b side of the main body 1, and the bolts and nuts 14 are tightened and fixed using the holes 6 of the main body 1 and the holes of the pedestal part 13.

Therefore, the bent edge 5 on the long piece 4a side of the presser metal fitting 4 of this invention and the upper surface of the main body 1 form the bracket mounting metal fitting 1.
2, and the long piece 4a of the presser metal fitting 4 and the end of the U-shaped part 1a are pressed against both the front and rear surfaces of the bracket mounting metal fitting 12. With this device, the outer side of the bracket mounting metal fitting 12 is pressed. This device is firmly fixed to the bracket mounting fittings 12 by holding the four circumferential sides. Therefore, even if devices such as the short-circuit current passage indicator 9 are attached to the other side of the main body 1 of this invention, there is no risk of the device becoming unstable.

In addition, if the bracket mounting bracket 12 is made of an angle material as shown in FIG.
2a, the U-shaped groove of the U-shaped portion 1a is engaged with the edge of the horizontal piece 12a, and the long piece 4a side of the holding bracket 4 is attached to the lower edge of the vertical piece 12b of the bracket mounting bracket 12'. Lock the curved edge 5, overlap the long piece 4a with the front of the vertical piece 12b, bring the bent edge 5 end of the short piece 4b into contact with the lower surface of the main body 1, and press the presser metal fitting 4.
The tip of the thumbscrew 7 inserted through the hole 6 of the short piece 4b of
When the thumbscrew 7 is tightened, the horizontal piece 1 of the angle-shaped bracket mounting bracket 12'
2a and the edges of the vertical piece 12b, the U-shaped groove of the U-shaped portion 1a and the bent edge 5 of the holding metal fitting 4 are engaged, and the bracket mounting fitting 12' is held between the main body 1 and the holding metal fitting 4. This idea is based on the bracket mounting bracket 1.
2' is firmly fixed. Similarly to the above, the short circuit current passage indicator 9 is mounted and fixed on the wide portion 1b side of the main body 1.

In addition, as shown in Fig. 6, the bracket mounting bracket 1
If the cross section of 2' is a small angle material,
This is almost the same as the case shown in Figures 4 and 5, but
The bent edge 5 on the short piece 4b side of the presser fitting 4 is locked to the lower edge of the vertical piece 12b of the bracket mounting fitting 12'',
Bring the bent edge 5 end of the long piece 4a into contact with the bottom surface of the main body 1, insert the thumbscrew 7 into the hole 6 of the long piece 4a, and insert the tip of the screw into the U-shaped part 1a of the main body 1. hole 2
It is screwed onto the

Furthermore, Fig. 7 shows the installation state of this device when the position of the angle member of the bracket mounting bracket 12' is different from that described above, but in this case, the top and bottom of Fig. 5 A and B are reversed. is in a state of
The mounting structure of this invention to the bracket mounting fitting is similar to that shown in FIGS. 5 and 6.

As mentioned above, this device is a bracket mounting bracket 1
Regardless of whether the shape of the bracket 2 is a narrow plate or an angle bar, or a small angle bar, the bracket mounting metal fitting 12 is held by the U-shaped portion 1a of the main body 1 and the bent edge 5 of the pressing metal fitting 4. Moreover, regardless of the shape of the bracket mounting metal fitting 12, the long piece 4a or the short piece 4b of the pressing metal fitting 4 will be held by the U-shaped portion 1a of the main body 1 and the bent edge 5 of the pressing metal fitting 4.
The plate members 4 and 5 are approximately parallel to the main body 1 at a fixed distance, and it is easy to fasten these two plates with the thumbscrews 7. In this way, even if the shape of the support body such as the bracket mounting metal fitting 12 is various, the pressing metal fitting 4 can be easily fixed.
By changing the positions of the long pieces 4a and short pieces 4b or by making various use of the U-shaped portion 1a of the main body 1 and tightening the thumbscrew 7, one side of the main body 1 can be very easily fixed to a support, and various devices such as a short circuit current passage indicator 9 can be attached to the other side of the main body 1.
