Laser vertical rotation automatic positioning direct reading compass

Abstract

The invention discloses a laser vertical rotation automatic positioning direct reading compass, and relates to the field of compass devices. The problems that the compass is time-consuming to use and the subject matter not located on the horizontal plane of the compass cannot measure the orientation are solved. An outer disc of the laser vertical rotation automatic positioning direct reading compass is provided with a lantern ring, a movable fixed die sleeve is placed in a square groove, and the fixed die sleeve is provided with a bolt for adjusting the direction of a laser head; and a rotating ring plate is arranged in the middle of the outer side of a cylindrical outer box of the heaven pool, and a ball screw is installed in a square groove. The compass is simple in structure, convenient to use and capable of achieving multi-angle azimuth measurement.

Description

technical field [0001] The invention relates to a compass device, in particular to a laser vertically rotating automatic positioning direct-reading compass. Background technique [0002] The compass used by people consists of three parts: the Tianchi, the inner disk and the outer disk. The Tianchi is composed of a thimble, a magnetic needle, a submarine line, a cylindrical outer box, and a glass cover; The various contents of the dial are engraved on the dial; the outer dial is usually square, and the crystal lines passing through the center hole outside the four sides of the outer dial form the Tianxin Ten Dao, or positioning lines, which are used to read the contents on the inner dial. At present, the compass used is to directly embed the Tianchi and the inner disk into the outer disk. When using the compass, first align the target with the positioning line on the outer disk, and then rotate the inner disk and the Tianchi to adjust until the magnetic needle coincides with ...

Problems solved by technology

When measuring the next target, it is still necessary to repeat the same steps above. First align the target and then adjust the magnetic needle and the seabed line to read the data, instead of directly reading the data after aligning the target. This method is suitable for different targets. The measurement steps that need to readjust the coincidence of the magnetic needle and the bottom line not only bring a certain degree of difficulty to beginners, but also cause a waste of time for frequent users

[0003] When measuring the azimuth of the target object, the level installed on the outer disk is usually adjusted to a horizontal state first, and then the target object is measured, but the target object above and below the compass level cannot be aligned with the target object after tilting the entire compass. Therefore, using the existing compass to measure the azimuth of the target above or below the compass level cannot be aligned and measured.
