Abstract

The detection instrument triangular support of the utility model relates to the detection instrument auxiliary device, which is composed of a column and three legs, and the column is a sleeve telescopic structure with more than two sections, and its bottom is fixedly connected with a universal joint ball. The universal joint ball is built into the table and connected with it in the gap. The lower edge of the table is evenly hinged with the tops of the three legs. The universal joint ball is fixed on the table by bolts after being pressed by the chuck sleeve. . The triangular support of the detection instrument of the utility model has an ingenious structural design, which overcomes the problem of designing longer legs of the traditional triangular support to adapt to the inclined ground. The length of the three legs of the utility model is relatively short, and it only plays a supporting role. This device relies on the upper column to adjust its center of gravity and the level of the top instrument platform, so the overall weight is lighter, and it can ensure that the center of gravity is always integrated with the column and perpendicular to the center of the earth, which ensures the stability of the whole when tilting the ground surface, so The column always coincides with the direction of the center of gravity, and is free to shrink, easy to use, and easy to carry.

Description

Testing instrument tripod bracket

technical field

The utility model relates to a detection instrument auxiliary device, in particular to a detection instrument triangular support.

Background technique

In the construction process of the project, many detection links will be involved, the most common ones are theodolite detection, noise detection, etc. The use of these instruments is placed on a tripod stand and stabilized. The principle is the same as that of a camera using a tripod stand. However, the detection in the project is carried out outdoors or in the wilderness, the detection conditions are harsh, especially the ground is uneven, and even the ground at the detection point has a certain slope, and the existing tripod is stretched through the lower leg To overcome the above-mentioned problems, but when the three legs are opened on the ground with a large inclination, at least one leg needs to be stretched out quite long to ensure that the upper part of the overall support is in a horizontal state. The larger the inclination angle of the ground surface, the longer the telescopic legs are required. In this way, it is not only inconvenient to use, but also increases the overall weight of the tripod, which increases the cost and increases the overall weight, making it inconvenient to carry.

Utility model content

The utility model aims at the technical problems existing in the background technology, and provides a detection instrument triangular support.

The triangular bracket of the detection instrument of the utility model is composed of a column and three legs, the column is a sleeve telescopic structure with more than two sections, the bottom of which is fixedly connected with a universal joint ball, and the universal joint ball It is built into the platform and fits with it in clearance. The lower edge of the platform is uniformly hinged with the tops of the three legs, and the universal joint ball is fixed on the platform by bolts after being pressed by the chuck sleeve.

As a further improvement of the utility model, a vertical column is fixedly connected to the bottom of the platform, and a disc is sleeved on the vertical column, and a supporting rod is provided between the disc and each supporting leg to be hinged.

As a further improvement of the utility model, a locking device is provided on the disc.

As a further improvement of the utility model, the vertical column at the lower part of the disc is provided with a limit card platform.

The triangular support of the detection instrument of the utility model has an ingenious structural design, which overcomes the problem of designing longer legs of the traditional triangular support in order to adapt to the inclined ground. The length of the three legs of the utility model is relatively short, and it only plays a supporting role. This device relies on the upper column to adjust its center of gravity and the level of the top instrument platform, so the overall weight is lighter, and it can ensure that the center of gravity is always integrated with the column and perpendicular to the center of the earth, which ensures the stability of the whole when tilting the ground surface, so The column always coincides with the direction of the center of gravity, and is free to shrink, easy to use, and easy to carry.
