Description

A portable tree branch angle measuring instrument

technical field

The utility model relates to the technical field of tree branch angle measurement, in particular to a portable tree branch angle measuring instrument.

Background technique

The current tree branch angle measurement device needs to hold the measuring piece by hand when measuring, and the measuring piece cannot be fixed on the tree, resulting in large errors in the measurement process. It is not possible to measure at the same time. It is necessary to adjust the position of the measuring piece after measuring one. The measurement process is time-consuming. Sometimes the position of the measuring piece is deviated because the measurer fixes the measuring piece by hand for a long time, which affects the measurement. result.

Utility model content

The purpose of this utility model is to overcome the problem that the existing measuring device cannot be fixed on the tree, the measurement result is inaccurate, and the branches at two angles at the same position cannot be measured, and to provide a measuring device with two angles at the same position. The branches can be measured at the same time, and can be fixed on the tree. It is a portable tree branch angle measuring instrument with accurate measurement results.

Above-mentioned purpose realizes by following technical scheme:

A portable tree branch angle measuring instrument, which consists of: three fixers, the three fixers are connected by elastic return ropes, the fixer includes a bottom plate, and the bottom plate has a T shaped hole, the rear end of the bottom plate is provided with two positioning plates arranged parallel to each other, the two positioning plates are respectively perpendicular to the bottom plate, and the fastening bolts pass through the T-shaped hole and the The above positioning plate is threaded, the front end of the base plate is provided with a measuring angle plate, and the center of the measuring angle plate is fixed with a fixing bolt, and the fixing bolt passes through the T-shaped hole and the base plate. Nut connection.

In the portable tree branch angle measuring instrument, the protractor plate is an integral structure formed by butting two semicircular protractors, and the protractor has a scale.

In the aforementioned portable tree branch angle measuring instrument, the height of the lower end of the positioning board is greater than the center height of the angle measuring board.

The beneficial effects achieved by the utility model are:

1. The working principle of this utility model is: adjust one of the fixers according to the diameter of the trunk to adjust the distance between the two positioning plates, fix it on the trunk, which is suitable for trees with different diameters, and then fix the other two The device is respectively fixed on two branches with different angles, and the angle of the two branches can be measured. If there is a small change in the height of the two branches, after measuring the angle of one of the branches, loosen the nut. Then slide the angle plate up or down so that the anchor bolt is at the intersection of the trunk and the branch to measure the angle of another branch without re-fixing the anchor.

2. The utility model can measure two branches with different angles at the same position at the same time, which saves the time for adjusting the measuring parts and improves the measurement efficiency.

3. The utility model can adjust the angle measuring board up and down, so that the center of the angle measuring board is at the intersection of the trunk and the branch, and the measurement result is more accurate.

4. The fixer of the present utility model can be fixed on a tree trunk or a branch, and does not need to be fixed by a surveyor by hand, so as to prevent the position of the fixer from shaking or changing, and improve the accuracy of measurement.

5. The height of the lower end of the positioning plate of the utility model is greater than the center height of the measuring angle plate, so that the positioning plate is above the intersection point of the trunk and the branches, so that the measuring angle plate can slide up and down according to the position of the intersection point of the trunk and the branches, Improve the accuracy of measurements.

6. For the elastic return rope provided in the utility model, the two ends of the elastic return rope are sleeved on the fixing bolts of the two fixers, and the length can be adjusted to facilitate measurement at different positions.

7. The utility model has simple structure and light equipment, which can be carried to any place to measure the angle of tree branches, and the measurement is convenient.
