Description

[Detailed Description of the Invention] The present invention relates to a stand for equipment such as industrial fans.

1 and 2 are conventional examples. Conventionally, a nut 2 is fixed in the upper part of a pipe-shaped leg 1, and a bolt 4 inserted into the leg 1 from the upper surface of a mounting plate 3 is inserted into the nut. 2, the three legs 1 were fixed to the mounting plate 3.

However, with this structure, the leg 1 would shake against the mounting plate 3 unless the nut 2 was securely fixed to the leg 1.

Furthermore, fixing the nut 2 to the leg body 1 requires complicated operations such as press-fitting and caulking, which increases the number of man-hours and is inefficient.

Furthermore, the cylindrical regulating plate 5, which holds the legs 1 together and prevents the legs 1 from spreading, is not fixed to the legs but to the mounting plate 3, so there is no possibility of rattling due to molding errors, etc. It was unstable.

Further, since the head of the bolt 4 protrudes from the top surface of the mounting plate 3, it is not possible to secure a device with a flat bottom surface, and it is necessary to form a relief recess for the head on the bottom surface of the device. .

In view of the above points, the present invention provides a stand in which the attachment plate and the legs can be connected and the positions between the legs can be reliably performed without rattling. The explanation will be based on.

Reference numeral 11 denotes the proposed stand, which consists of a mounting plate 12 to which the main body of the equipment is attached, three pipe-shaped legs 13 attached to the lower surface of the mounting plate, and three pieces connecting adjacent legs. 3 for tightening and fixing the above-mentioned three members.
It consists of bolts 15 and nuts 16.

The connecting cover plate 14 has semicylindrical groove portions 17 formed on both sides to cover the side surfaces of the leg body 13.

By placing the curved portion 17 of the connecting cover plate 14 over the side surface of the upper part of each leg 13, the legs 13 are positioned so as to form an equilateral triangle.

The curved portion 17 has bolt insertion holes 1B located above and below,
19, and through holes 20 and 21 passing through the center of the leg are formed at the upper part of the leg 13 corresponding to the insertion holes 18 and 19.

The bolt 22 is inserted through the lower insertion hole 19 of the connecting cover plate 14 that covers one half side of the leg body 13 and passes through the lower through hole 21, and the lower part of the connecting cover plate 14 that covers the other side of the leg body 13 is inserted. It is made to protrude from the hole 19.

By screwing a nut 23 into the tip of the protruding bolt 22, each leg body 13 and each connection cover plate 14 are integrally fixed.

The mounting plate 12 is provided with three pairs of hanging pieces 25, each of which has an insertion hole 24 through which the mounting plate fixing bolt 15 is inserted.

When the mounting plate 12 is placed on the leg body 13, the hanging piece 25 is positioned so as to sandwich the leg body 13 from the outside of the connection cover plate 14, and the insertion holes 24, 24 and the insertion hole 1B, 18 and the through hole 20 match.

Insert the bolt 15 into the hole 24, 18.20,
A nut is screwed into the projecting end to integrally connect and fix the mounting plate 12, the connecting cover plate 14, and the leg body 13.

Therefore, when the stand 11 is assembled, the mounting plate 12, the connecting cover plate 14, and the leg body 13 are tightened and fixed with the bolts 15 that pass through each member. Even if there are some errors, the process is performed reliably without any wobbling.

Further, the external force applied to the leg body 13 is not concentrated on the connecting portion, but is distributed over the connecting cover plate 14, thereby improving the strength of the connecting portion.

Further, the horizontal force applied to the mounting plate 12 is applied to each side of the equilateral triangle formed by the bolts and in the direction perpendicular thereto, and even if the force is distributed and applied, the force is applied centered on the mounting plate 12. The strength of the part is improved.

In addition, an equilateral triangle formed by the bolt 15 and the leg body 13
The equilateral triangles formed by the above overlap each other with a 60 degree shift, and each vertex forms a hexagon, so the direction of dispersion of the force applied to the mounting plate 12 and the direction of dispersion of the force applied to the leg 13 overlap at one point. This prevents force from being concentrated on the stand, further improving the strength of the stand.

As described above, the present invention consists of a hanging piece that hangs down from a mounting plate to which the main device is attached, a plurality of pipe-like legs, and a connecting cover that covers the outer periphery of the adjacent part of the upper part of the legs and connects the adjacent legs. Since these are fixed with a tightening member that passes through each part, the three parts can be reliably fixed integrally without wobbling.

Further, since the legs are not fixed individually but are interconnected by connecting plates, the external force applied to the legs is dispersed and the strength of the stand is improved.

Furthermore, since there is no protruding part on the upper surface of the mounting plate, it has great practical effects, such as being able to support devices that could not be supported conventionally.
