Description

Horizontal adjustment supporting seat

Technical Field

The utility model discloses be suitable for the level adjustment of measuring the base, be suitable for thick level adjustment such as accurate angular surveying instrument installing supports such as theodolite very much.

Background

Optical instruments such as theodolite, autocollimator need carry out the horizontal coarse adjustment of support before accurate angle measurement, because need remove the support and look for suitable position in the test process, and test environment ground because of material, hardness difference, and unevenness, when fixed level adjustment support area of contact is less, even support removal in-process at the instrument, can fish tail ground, wearing and tearing support.

SUMMERY OF THE UTILITY MODEL

In order to solve not enough among the prior art, provide one kind and can realize making level roughly, and stability is good to the support base that is used for erectting accurate optical instrument of ground not damaged, the utility model discloses the technical scheme who adopts is:

a horizontal adjustment supporting seat comprises a supporting plate for mounting an optical instrument, wherein three supporting legs are arranged in a central circular array of the supporting plate; the support leg include the regulation pole of outband screw thread be equipped with the screw hole of installing each regulation pole in the backup pad the regulation pole on be equipped with and twist the head soon, the regulation pole on keep away from and twist the head one end soon and be equipped with the diameter and be less than the thin neck of adjusting the diameter thin neck one end be equipped with the bulb that the diameter is greater than the thin neck diameter, still including the supporting shoe on be equipped with and hold the bulb and enable the counter bore including the bulb activity, the supporting shoe on still be fixed with the opening piece, the opening piece on be equipped with the U type opening of card in thin neck department, U type opening width be greater than thin neck diameter and be less than bulb diameter.

Thereby each regulation pole can realize altitude mixture control through screwing the head and reach the level adjustment to the backup pad, and the bulb realizes the free activity in the counter bore, and the supporting shoe is arranged ground static in, can provide fine support and can avoid damaging ground again, adopts the opening piece can prevent that the bulb from breaking away from the counter bore, and convenient equipment and dismantlement.

Detailed Description

As shown in figure 1, the adjusting support seat comprises a support plate 1, three support legs 2 are arranged on the support plate 1, each support leg 2 is circularly aligned with the center of the support plate 1, the support legs 2 as shown in figures 2 and 3 comprise an adjusting rod 2-1, a screwing head 2-2, a thin neck 2-3, a ball head 2-4, a support block 2-5 and an opening sheet 2-7, the adjusting rod 2-1 is provided with external threads, the support plate 1 is provided with a threaded hole 1-1 for installing the adjusting rod 2-1, the screwing head 2-2 is fixed at the upper end of the adjusting rod 2-1, the height of the adjusting rod 2-1 is more conveniently adjusted by rotating the adjusting rod 2-1 through the screwing head 2-2, the thin neck 2-3 is arranged at one end of the adjusting rod 2-1 opposite to the screwing head 2-2, and the diameter of the thin neck 2-, the end part of the thin neck 2-3 is provided with a ball head 2-4, the diameter of the ball head 2-4 is larger than that of the thin neck 2-3, the support block 2-5 is provided with a counter bore 2-6, the ball head 2-4 is arranged in the counter bore 2-6 and can move freely, the opening piece 2-7 is fixed on the support block 2-5, the opening piece 2-7 is provided with a U-shaped opening 2-8, the U-shaped opening 2-8 is clamped at the thin neck 2-3, the width of the U-shaped opening 2-8 is larger than that of the thin neck 2-3 but smaller than that of the ball head 2-4, the ball head 2-4 can be prevented from falling off from the counter bore 2-6 while the rotation of the ball head 2-4 is ensured, the installation is quite convenient, after the ball head 2-4 is arranged in the counter bore 2-6, the U-shaped opening 2-8 on the opening piece 2- The blocks 2-5 can be post-mounted. The precise optical instrument is installed on the supporting plate 1, the level of the supporting plate 1 is adjusted by rotating the screwing head 2-2, the supporting block 2-5 is always in contact with the bottom surface to provide support in the process, the ball head 2-4 is movably arranged in the counter bore 2-6 to ensure that the adjusting rod 2-1 can rotate, so that the supporting plate 1 is provided with enough support, meanwhile, the damage to the ground can be avoided, the rough leveling of the optical instrument can be realized through the supporting seat, and then the precise leveling can be realized through the leveling device on the optical instrument.
