Description

[Detailed description of the invention] This invention is a support for a distribution board that is used in various types of distribution boards, and has a support that is fixed on the base and has a middle plate attached to the tip of the support so that it can be attached or removed or rotated to open and close at a certain angle. The length of the support can be easily adjusted by constructing the support with an outer cylinder and a support shaft fitted into the outer cylinder.

Conventionally, all of the above pillars are made of round bar materials and are welded directly onto the base and fixed in place.The length of the pillars varies depending on the size (model) of the distribution board. Electrical parts are almost tight.
If these parts are made by the same manufacturer, their height dimensions are also constant, so we mass-produce pillars with fixed dimensions that match this, and weld them onto the base to secure them in place.

Therefore, a large number of pillars of various types, such as small and large, with basic dimensions that match the size of the distribution board, are prepared in advance and used by welding them to each distribution board. .

However, normally, the electrical components installed in a distribution board vary depending on the purpose of use, etc., and changes may occur even after design, manufacture, and installation, and parts from various manufacturers may be mixed together. For this reason, it is often necessary to change the length of the support.

Therefore, in the past, when the dimensions of the support pillar were changed at the time of the initial manufacture of the distribution board, the basic dimensions (off-the-shelf preparation) were changed.
It is used by cutting to make it shorter, or by welding additional parts to make it longer.Also, after welding the support to the base, there is a screw structure at the tip for fixing the middle plate, so it is necessary to cut it. Since it is not possible to do any additional welding, we have no choice but to remove all of the welded supports, replace them with ones of different dimensions, and re-weld them.In this case, we have to repaint the entire thing. Although it was possible to do this in a manufacturing factory, since work could not be done on-site in a building, the entire switchboard had to be removed and brought back to the factory, which was extremely inefficient and uneconomical work. .

Therefore, the present invention was devised to solve the above-mentioned conventional drawbacks, and by configuring the column with an outer cylinder and a support shaft that is slidably inserted into the outer cylinder, it is possible to improve the distribution board. Whether in a manufacturing factory or at an installation site in a building, etc., it is extremely easy to adjust the length of the support column by sliding the support shaft up and down against the outer cylinder, and by holding the adjusted length with a set screw. It is configured so that it can be used immediately.

That is, to explain the configuration of the present invention with reference to its embodiments, various electrical components P such as breakers are wired and installed on a base 3 that is appropriately attached to the back plate inside a box 1 with a door 2, and set positions ( For example, a plurality of struts A are fixed to the four corners) by welding or by screwing screws 6 or nuts 7 to the female and male screw structure at the lower end of the struts, and the middle plate 4 is placed on the struts A at the tip of the struts A. It is removably fixed by screwing the screw 6 or nut 7 to the female and male thread structure of In a distribution board that can be rotated to open and close at a certain angle by being attached to a hinge mechanism D provided at the tip of a column, the column A is composed of an outer cylinder B and a support shaft C, and has a cylindrical or hexagonal shape. One or more screw holes 8 for screwing the set screw holes 11 are screwed into the circumferential surface in the axial direction of a cylindrical body such as a cylinder at set intervals (for example, at positions of 5 mm, 7.5 mm, and 10 mm from the top end). If necessary, a female and male screw structure 5 or an appropriate hinge mechanism D is provided at the upper end in the hollow part 9 of the outer cylinder B, which is provided with a female and male thread structure 5 at the lower end, and circumferential grooves 10 are formed on the circumferential surface at equal intervals (e.g. , 5mm
Insert the cylindrical support shaft C cut into the outer cylinder so that it can slide up and down, and at the position where the support shaft C is slidably adjusted to configure the support support A to the set length, tighten the set screw 11 into the outer cylinder. By screwing into the circumferential groove 10 of the support shaft C that matches the appropriate screw hole 8 from the appropriate screw hole 8 of B, the length of the support column A can be freely adjusted to the desired length. It was made so that it could be done.

In addition, in the case of the above-mentioned outer cylinder B, which has a female and male thread structure 5 formed at its lower end as necessary, when fixing the structure to the base 3, the screw 6 is screwed into the female thread structure 5, or the nut 7 is screwed into the male thread structure 5. or by directly screwing into the base 3 using the male thread structure 5 as a tap, and if the female and male thread structure 5 is not formed at the lower end, the base 3
Fixed by welding.

In addition, the attachment and detachment of the middle plate 4 from the tip of the support shaft C is performed by screwing a screw 6 or a nut 7 into the female and male screw structure 5 provided at the tip or the female and male thread structure 5 provided at the hinge mechanism D. .

In the above-mentioned female and male screw structure, which side is the female thread and which side is the male thread, which side is screwed and nutted, etc. are completely arbitrary because they are relative to each other.

The circumferential groove 10 is cut into the circumferential surface of the shaft C at equal intervals, for example, every 5 mm over the entire length of the shaft C, while the screw holes 8 screwed into the outer cylinder B side are spaced apart from the circumferential groove 10 at intervals of, for example, every 2.5 mm from 5 to 7.5 to 10 mm, or every 4 mm from 4 to 8 to 12 mm, or
The threads are screwed in at 3 mm increments of 3 to 6 to 9 mm, or further at dimensions that combine the 2.5 mm and 4 mm increments.

Therefore, for example, the circumferential groove 10 of the support shaft C is cut every 5 mm, and this is inserted into the outer cylinder B in which three screw holes 8 are screwed every 2.5 mm from 5 to 7.5 to 10 mm. Adjust the vertical sliding of the support shaft C to minute dimensions so that one of the three screw holes 8 coincides with one of the circumferential grooves 10, and screw the set screw 11 into the matched screw hole 8 to attach the support shaft. By setting the length of A, it is possible to adjust the dimensions up to 2.5 mm.

For example, if there is one screw hole 8 in the outer cylinder B for each circumferential groove 10 of the support shaft C every 5 mm, the adjustment capacity can be doubled compared to the case where the size can only be adjusted in 5 mm increments. It is a must have.

Therefore, although there are dimensional limitations in manufacturing, the combination of the set dimensions of equally spaced cuts of the circumferential groove 10 on the support shaft C side and the set screw spacing of the threaded holes 8 on the outer cylinder B side with respect to the set dimensions Therefore, there is a feature that allows minute dimensional adjustment of the support column A.

In addition, if the outer cylinder B is directly screwed into the base 3 using the lower end female and male screw structure 5 as a tap, or directly fixed by welding, if the fixing position is incorrect, the support column A This may be a problem because it does not match the opening/closing direction of the hinge mechanism D at the upper end, and it is impossible to correct that direction. Since it can freely slide up and down as well as rotate, the opening and closing direction of the hinge D can be freely adjusted to any direction, and at that time, since the counterpart to which the set screw 8 is threadedly engaged is the circumferential groove 10, It has the advantage of not causing any problems.

As described above, the proposed strut is composed of a simple outer cylinder and a support shaft, and the length of the strut can be adjusted and set to minute dimensions as described above, and the set length can be adjusted with a set screw. If it is locked, the strength and safety of the support pillars will not be inferior to conventional support pillars, and therefore it will be used not only in distribution board manufacturing factories but also at installation sites such as factories and buildings. Even if there is a change, by immediately slidingly adjusting the support shaft C according to the height of the part P, etc., and locking the set screw 11,
Supports of any length can be freely configured to allow for correct installation of the middle plate. These functions and effects cannot be achieved at all with conventional pillars in which pillars of fixed size are established and fixed by welding.
