Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the structure of a device mounting part for, for example, a distribution board.

[Conventional technology and its problems]

For example, when devices such as breakers and switches are attached to the base of a power distribution board, these devices are covered with a panel, and the operation parts and the like are projected or exposed on the panel.

Furthermore, the panel covering the equipment is supported at the four corners of the panel by screwing panel receiving nuts and panel retaining nuts into bolts planted and fixed to the base.

By the way, even if the surface of the equipment installed on the board is even, if the board is wavy, the panel may tilt to the surface of the equipment when the four corners of the panel are supported with bolts at a certain height. Such an incline is not only extremely unsightly, but also impedes the operation of equipment.

There is also a floor panel support that consists of a pair of cylinders with panel clamping flanges fitted with male and female screws as panel support bolts, and a rod (threaded rod) that is screwed into the lower cylinder (Utility Model No. 54-56927). issue).

The above-mentioned support is a floor panel support when constructing the floor panel by laying it on a concrete slab, and its height can be adjusted by tapping the upper end of the threaded rod that appears in the axial hole of the lower cylinder on the panel. This is done by fitting the tip of a screwdriver into the shape notch and rotating the threaded rod in either the forward or reverse direction.

Therefore, this floor panel support not only has the risk of spontaneous rotation due to the vibration of the floor panel, but also cannot be used for fixing a panel that covers equipment in a distribution board or the like.

In addition, some bolts that support two members at a predetermined distance use a locking nut to ensure fastening after adjusting the distance (Utility Model No. 51-132477).
issue).

However, this spacing adjustment support device is fully exposed between the two members and allows bolts and nuts to be easily tightened, so this device is also not used for equipment attachments such as distribution boards. It's something you can't get.

The purpose of this invention is to create a structure for equipment mounting parts for distribution boards, etc., in which a panel covering equipment is supported by bolts planted and fixed on the base, and the panel can be finely adjusted to a horizontal position by operating on the panel. It is in.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention uses an adjusting bolt nut as a panel support bolt that is planted and fixed on the base, and this adjusting bolt nut includes a bolt body, an adjusting nut screwed into the bolt body, an adjusting nut tightening nut, It consists of a panel fastening nut to be screwed into the adjusting nut, the bolt body is a threaded rod with a thread formed over its entire length, the adjusting nut is provided with a deep female threaded hole into which the other end of the bolt body is screwed from one end of the shaft part, and At the other end of the shaft rod, a small diameter screw shaft into which a nut for panel tightening is screwed is connected via a panel receiving part, and a groove for fitting the tip of a driver is formed at the tip of the screw shaft. The bolt body is planted and fixed on the installed base, and the adjustment nut tightening nut and adjustment nut are screwed into the bolt body in that order.The panel is received on the stepped part of the adjustment nut, and the panel is attached to the small diameter screw shaft of the adjustment nut that protrudes from the panel. This structure is used to attach a device such as a distribution board to which a tightening nut is screwed.

〔Example〕

Fig. 1 shows an example of a device mounting section in a distribution board, 1 is the base of the device mounting section, 2 is a device such as a breaker attached to the base 1, and 3 is a top view of the operating operation section 4 of the device 2. panels that cover equipment exposed to
Reference numeral 5 denotes a bolt planted and fixed on the base 1 to support and fix the panel, and this bolt is an adjustment bolt nut that can be adjusted with the panel installed so that the panel is aligned and horizontal with the surface of the equipment. As shown in an enlarged view in FIG. 2, it consists of a bolt body 6, an adjustment nut 7 screwed into the bolt body, an adjustment nut tightening nut 8, and a panel tightening nut 9 screwed into the adjustment nut 7.

The bolt body 6 is a threaded rod 11 having a thread 10 formed over its entire length, and is welded to the base 1 at one end. 12 is the welded portion.

However, instead of welding, it is also possible to screw the threaded rod 11 into the base 1 and tighten it with a nut.

The adjuster nut 7 has a deep female screw hole 14 into which the other end of the bolt body 6 is screwed into one end of the shaft portion 13.
The other end of the shaft rod portion 13 has a small diameter threaded shaft portion 15 into which the panel fastening nut 9 is screwed.
They are connected via a panel receiving step 16, and a screwdriver tip fitting groove 17 is formed at the tip of the screw shaft portion 15.

In order to attach the panel 3 that covers the equipment 2 using the bolts 5, the bolt bodies 6 are planted and fixed on the base 1 at positions corresponding to the four corners of the panel 3, and the adjusting nuts 8 and 7 are attached to the bolt bodies. are screwed in this order, and then the threaded shaft portion 15 at the other end of the adjuster nut 7 is passed through the hole 18 formed at the four corners of the panel 3, and the panel is received by the stepped portion 16.

In this state, it is assumed that the positions of the panel and the bolts 5 are set so that the actuating operation part 4 of the device 2 protrudes from the hole 19 formed in advance in the panel 3.

Next, with the panel 3 supported by each bolt 5,
Check whether the panel is parallel to the surface of the device 2. If it is not parallel, tighten the adjuster nut 7 of one of the bolts, and insert the tip of a tri-bar (not shown) from the front side of the panel 3 to the tip of the screw shaft 15. After fitting into the groove 17 and adjusting the panel to be parallel to the surface of the device 2 by screwing or loosening the adjuster nut with a screwdriver, turn the adjuster nut fastening nut 9 to tighten the adjuster nut 7, and finally screw shaft portion 15. Screw in the panel tightening nut and tighten. 2a is a low-height device such as a switch, and this device 2a also has its surface connected to the device 2.
When installing the device 2a, the base 20 consisting of a panel should be supported with short bolts 5a, and the base 20
The height and horizontal position of the bolt 5 are adjusted in the same manner as the adjustment of the bolt 5 described above.

It is assumed that the equipment 2a is installed before the panel 3 is installed.

[Effects] The structure of the device mounting portion for the distribution board, etc. of this invention provides the following effects.

(1) A panel support bolt consists of a bolt body, an adjusting nut screwed into the bolt body, a nut for tightening the adjusting nut, and a nut for panel tightening to be screwed into the adjusting nut.The bolt body is a threaded rod with threads formed over its entire length, and the adjusting nut is One end of the shaft has a deep female screw hole into which the other end of the bolt body is screwed, and the other end of the shaft has a small diameter threaded shaft into which a panel fastening nut is screwed, connected via the panel holder step. In addition, since the screw shaft has a groove for fitting the tip of the screwdriver at the tip, this bolt can be planted and fixed on the board on which the device is mounted at positions corresponding to the four corners of the panel covering the device, and then tightened with the adjusting nut. Support the panel on the panel holder and make the small diameter screw shaft protrude above the panel, fit the tip of a screwdriver into the groove at the end of the screw shaft, and screw in or loosen the adjustment nut to remove the top surface of the panel. The horizontality of the panel can be easily and reliably adjusted from the side.

(2) Also, by using the structure of the equipment mounting part of this invention, even if there are multiple types of equipment with different heights, the equipment with lower heights can be mounted on a higher base made of bolts and panels. You can attach equipment and align the surface position with taller equipment.
