Description

A tripod stand for fixing the level

technical field

The utility model relates to an auxiliary device for level measurement, in particular to a tripod bracket for fixing a level gauge.

Background technique

Leveling is a basic work in surveying and mapping, and it also occupies an important position in some related testing work. With the increasing importance of leveling, how to improve the accuracy of measurement has also been highly valued by relevant departments. In the process of leveling, it is often necessary to hold the leveling staff or fix the leveling staff with a simple support of a stick, which has disadvantages such as poor stability, low leveling accuracy, easy fatigue of the staff holding the staff, and low labor efficiency.

Utility model content

The purpose of the utility model is to provide a tripod bracket with a fixed leveling rod, which has good frame stability, is convenient to carry and disassemble, and can improve measurement accuracy.

In order to achieve the above object, the technical scheme that the utility model takes is:

A tripod bracket for fixing a level rod, including a clamping member, a telescopic rod, a fastening bolt, and a connecting pin; the telescopic rod is hinged to the clamping member through the connecting pin, and the telescopic rod can rotate around the connecting pin; the leveling rod is fixed by the fastening bolt In the inner frame of the clamping member.

Further, the outer surface of the clamping member is C-shaped, the inner frame is rectangular, three sides are closed and one side is semi-closed; the front and one side of the outer surface of the clamping member each have a stepped hole, and the section of the stepped hole close to the inner surface of the clamping member is Threaded hole, a section close to the outer surface of the clamping member is a smooth hole.

Further, the polished rod section of the fastening bolt is located at the lower part of the fastening bolt, the threaded section is located at the upper part of the fastening bolt, and a groove is opened in the polished rod section.

Further, there are anti-slip pads one and two at the tail of the fastening bolt screw, and the first anti-slip pad and the two anti-slip pads are movably connected with the fastening bolts.

Further, there is a blind hole in the center of the surface of the anti-slip mat 1 and the anti-slip mat 2, and is covered by an iron sheet with a hole in the middle, and the holes on the iron sheet are aligned with the centers of the holes on the anti-slip mat 1 and the anti-slip mat 2; the anti-slip mat 1 The diameter of the blind hole on the anti-skid pad 2 is 1-2 mm larger than the diameter of the polished rod section of the fastening bolt.

Further, the iron sheet is fastened on the anti-slip pad 1 and the anti-slip pad 2 with screws.

Further, the circular vial is inlaid on the upper surface of the clamping member.

Due to the adoption of the above technical scheme, the beneficial effects obtained by the utility model are as follows:

The utility model has two fastening bolts for the level gauge, and has simple structure and easy operation.

The utility model optimizes the square clamping member into a circular shape, and designs the hole on the clamping member for fastening the bolt to fasten the level gauge as a stepped hole. After the level gauge is fastened, the screw head of the fastening bolt is located in the stepped hole. The light hole section can avoid the fastening bolts from scratching the clothes.

The utility model is equipped with three telescopic rods, which form a stable and reliable support for the leveling rod, good stability during use, high measurement accuracy, low labor intensity, less personnel requirements, and easy installation and disassembly.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

The tripod bracket for fixing the leveling rod described in this embodiment is suitable for fixing the leveling rod during high-precision leveling measurement.

When implementing the utility model, the specific operation method is as follows: as shown in Figure 1 and Figure 2, the clamping member 1 and the telescopic rod 2 are hinged through the connecting pin 7, so that the telescopic rod 2 can rotate around the connecting pin 7 at 0°～90° ° internal rotation. The circular vial 6 is inlaid on the upper surface of the clamping member 1 . Pass the fastening bolt 3 through the stepped hole on the surface of the clamping member 1, pass the anti-slip pad 1 4, the anti-slip pad 2 5 and the fastening bolt 3 through the holes on the anti-slip pad 1 4, the anti-slip pad 2 5 and the iron sheet 9 according to the figure Connect as shown in 3. Afterwards, the level gauge 8 is placed in the inner frame of the clamping member 1 , and the fastening bolt 3 is turned to fasten the level gauge 8 in the inner frame of the clamping member 1 . At this time, the screw head portion of the fastening bolt 3 is located in the smooth hole section of the stepped hole on the outer surface of the clamping member 1 as shown in FIG. 3 .

When in use, the telescopic rod 3 is opened so that it forms a certain angle with the leveling rod 8, the tripod is placed on the ground, and the telescopic rod 3 is adjusted so that the air bubble in the circular level bubble 6 is in the middle position, then the tripod is adjusted to be balanced. Work with the level gauge to measure.
