Description

[Detailed explanation of the invention] This invention uses a suction cup to suction and fix the legs of a desk on which measuring instruments, etc. are placed, on the floor, so that the height of the desk does not change even if the suction cup fails. This allows you to easily adjust your mood.

To explain the drawings, 1 in the drawings indicates the metal legs 3 of the desk 2.
A male screw rod 5 is provided on the upper part of the hexagonal part 4 to be screwed to the leg part 3, and a locking nut 6 is screwed to attach the male screw rod 5 to the leg part 3. The lower part of the hexagonal part 4 is fixed, and the lower part of the hexagonal part 4 is made small in diameter, and a fitting part 7 is provided, and a collar 8 is made to protrude from the lower end of the fitting part 7, and the inside of the fitting part 7 is defined as an empty tube 9.

Reference numeral 10 denotes a female screw for pulling up a suction cup 11, and the upper part of the hexagonal portion is formed into a concave shape to provide a housing portion 12, into which the fitting portion 7 of the male screw 1 is loosely fitted.

A set screw 13 to prevent the flange 8 from coming off is screwed onto the upper edge of the housing portion 12, and a screw punch 15 fixed to the suction cup 11 is screwed onto the screw portion 14 at the bottom of the hexagonal portion. Loosely insert the male screw 1 into the empty tube 9.

The suction cup 11 has a normal structure, with the lower end of a screw punch 15 fixed to the center of the suction cup made of vinyl chloride, a support bowl 16 made of a metal plate placed on the upper side, and a support bowl 16 made of a metal plate placed on the periphery of the support bowl 16. Support the load.

Thrust ball bearings 17 and 18 are interposed between the collar 8 at the lower end of the male screw 1 and the accommodating portion 12 of the female screw 10 and between the support bowl 16 and the female screw 10 to ensure smooth rotation. .

Reference numeral 19 denotes an insertion hole through which the female screw 10 is rotated by insertion of an insertion rod.

Place the suction plate 11 on a smooth surface, turn the male screw 4, adjust the height and horizontality of the desk 2, and tighten the locking nut 6. The load on the desk 2 is transferred from the collar 8 to the peripheral edge of the support bowl 16 via the female screw 10. , and is supported by the peripheral edge of the suction cup 11.

When the female screw 10 is turned and the screw punch 15 is pulled up, the screw punch 15 rises inside the empty tube 9, and the suction cup 11 is pulled up, causing the inside of the suction cup 11 to drop, creating a large suction force, which stabilizes the table 2 and prevents external forces from being applied. Even if the desk 2 is hit, it easily sticks to the smooth surface and does not move.

When suction cup 11 sucks air and loses suction force, turn female screw 10
The suction force of the suction cup 11 is restored by turning it back once, lowering the screw 15 to flatten the suction cup 11, and turning the female screw 10 again to raise the screw pestle 15 and pulling up the suction cup 11.

The left and right rotation of the female screw 10 moves only the screw punch 15 up and down, regardless of the rotation of the male screw 1, and does not change the height of the desk 2 and the metal fittings as a whole.

In this invention, since the screw punch 15 is housed in the empty tube 9 of the male screw 1 and moves forward and backward, the height of the entire metal fitting can be made relatively short, and the drop adjustment operation of the suction cup 11 is easy. There are practical benefits to being easy.
