Abstract

The invention provides a theodolite which comprises a base, a reference part is arranged above the base, a shielding piece is arranged above the reference part, the shielding piece comprises supporting rods, a stabilizing rod, a rotating rod and a shielding plate, wherein the supporting rods are located at the two ends of the reference part in the length direction, the stabilizing rod is located between the supporting rods, and the rotating rod is located above the two supporting rods; the supporting rod is rotationally connected with the rotating rod, a receding groove is formed in the surface of the rotating rod and surrounds the rotating rod by one circle, the upper end of the supporting rod is matched with the receding groove of the rotating rod, and a stabilizing cavity is formed in the position, located on the side wall of the receding groove, of the rotating rod and surrounds the rotating rod by one circle. A reinforcing piece inserted into the stabilizing cavity is arranged at the upper end of the supporting rod; the shielding plate is arranged on the outer wall of the rotating rod, and the projection area of the shielding plate is larger than that of the base. The measurement accuracy of the theodolite can be improved.

Description

technical field [0001] The present application relates to the field of theodolite, in particular to a theodolite. Background technique [0002] Theodolite is a measuring instrument designed according to the principle of angle measurement to measure horizontal and vertical angles. Theodolite is the mechanical part of the telescope, which enables the telescope to point in different directions. The theodolite has two mutually perpendicular rotation axes to adjust the azimuth and horizontal height of the telescope. A theodolite is a goniometric instrument equipped with an alidade, a horizontal dial and an index for reading, and a vertical dial and an index for reading. [0003] Notification number is that the Chinese patent of CN108489452A discloses a kind of electronic theodolite, comprises a base and the aiming part installed on the base, and the telescope installed on the aiming part, installs the position of the telescope on the aiming part with the axis of the telescope A...
