Description

A protective cover for the knob of a total station

technical field

The utility model relates to a protective cover for a knob, in particular to a protective cover for a total station knob.

Background technique

At present, during on-site survey or measurement, there may be many points to be measured, and it is inevitable to move measuring devices such as total stations with a small distance. During the movement, the instrument may fall due to carelessness or misoperation. fall, resulting in varying degrees of damage or direct damage to the screw knobs exposed outside the instrument; in addition, since there is no protective cover matching this complicated screw knob on the market, or some simple protective covers, it is also The knob can only be installed on the knob after being unplugged, which is extremely inconvenient to assemble or install.

Utility model content

In view of the above disadvantages, the utility model provides a protective cover for the knob of a total station, which not only has a simple structure and is convenient to install, but also has low cost and can be reused.

The technical scheme that the utility model adopts in order to achieve the above object is as follows:

A protective cover for the knob of a total station, characterized in that: the protective cover includes a first protective shell away from the total station body, a second protective shell in the middle part and a third protective shell close to the total station body The protective cover is divided into a left part and a right part from top to bottom, and the two parts are connected by a fixed connecting shaft. The connecting shaft is located on the second protective shell in the middle, and the connecting shaft is opposite The two sides of one side are respectively provided with matching button buckles and button holes, and the first protective shell, the second protective shell and the third protective shell are all provided with button buckles and button holes.

The left part of the protective cover is composed of the left part of the first protective shell, the left part of the second protective shell and the left part of the third protective shell, and the right part of the protective cover is formed by the first protective shell. The right part of the shell, the right part of the second protective shell and the right part of the third protective shell are composed.

The left part and the right part are connected by a fixed connection shaft. When the protective cover is in an open state, the left part and the right part can rotate around the fixed connection shaft. When it is in a closed use state, the protective cover The other side of the other side is buckled in the corresponding button hole with a button, and the left and right parts of the upper cover of the first protective shell are just closed, and now the protective cover just blocks the screw knob of the total station.

The cross-sectional dimensions of the first protective shell, the second protective shell and the third protective shell can be changed according to the specific size and style of the screw knob, so that the protective cover can just block the level of the screw knob.

The number of the protective shells can be determined according to the number of different cross-sectional dimensions of the screw knob itself on the total station instrument.

The third protective shell can be determined according to the specific form of the screw knob of the specific total station, whether it is necessary to set a closed cover plate, the closed cover plate is integrated with the third protective shell, and the closed cover plate A cover plate hole is provided, and the size of the cover plate hole corresponds to the size of the rotation shaft of the screw knob.

The closed cover is set according to whether there is a gap between the screw knob and the main body of the total station itself.

The beneficial effects of the utility model are: not only the structure is simple, the installation is convenient, but also the cost is low, it can be reused, and it can reduce or avoid the damage or damage to the screw knob caused by the accidental drop of the instrument during the use of the total station , to protect the screw knob of the total station.
