A Conveniently Adjustable Optical Level

Abstract

The invention discloses an optical level convenient for adjustment. The optical level comprises a base, a level body and a connecting bottom plate, wherein a tubular level and a tilting screw are arranged on the level body; a spherical cavity is formed in the connecting bottom plate; two placing grooves tangent to the spherical cavity are formed in the upper surface of the connecting bottom plate; a disk-like floating block is arranged in and fits with the spherical cavity; an oscillating rod passes through the center of the floating block and is vertically connected to the lower surface of the base by a thread; a stop nut and a spacing ring are arranged at the parts, at the upper and lower sides of the floating block, of the oscillating rod respectively; a circular shell filled with mercury is arranged at the lower end of the oscillating rod; a plurality of transparent upright columns are arranged on the circular shell; the upper ends of the transparent upright columns are communicated by a connecting pipe; the liquid levels of the mercury in the transparent upright columns are flush; at least three adjusting screws are arranged on the edge of the upper surface of the connecting bottom plate; the upper ends of the adjusting screws abut against the upper surface of the base. The optical level can rapidly complete a levelness initial adjustment procedure and has high levelness when a sight axis works.

Description

technical field [0001] The invention relates to a level, in particular to a high-precision optical level which is convenient for adjusting the levelness of the collimation axis. Background technique [0002] Leveling devices are mainly used to measure the height of a certain point or the height difference between two points in construction and other projects. Existing optical level measuring devices usually consist of a level and two leveling staffs. The level mainly includes a base connected to a tripod, a body rotatably connected to the base through a vertical shaft, and a The telescope, which is composed of objective lens, eyepiece, alignment lens and reticle, etc., is also equipped with a corresponding leveling structure on the body, so that the collimation axis of the telescope can be adjusted to a horizontal state during measurement. The leveling structure mainly includes a circular level set on the body to indicate whether the vertical axis is vertical, a tube level ...

AI Technical Summary

Problems solved by technology

[0003] An object of the present invention is to provide a conveniently adjustable optical level in order to solve the cumbersome initial adjustment process existing in the existing optical level adjustment structure, which can not only quickly and easily complete the initial level adjustment program, but also has Conducive to reducing the requirements for measuring personnel

[0004] Another object of the present invention is to provide a conveniently adjustable optical level to solve the problem that the collimation axis of the telescope tends to produce large errors during leveling in the existing optical level leveling structure, thereby affecting the measurement accuracy of the level. Leveling instrument, which can make the collimating axis of the leveling instrument have a high levelness during work, and at the same time, the parallelism of the collimating axis is not easily affected by the human factors of the surveyor and the manufacturing and assembly accuracy of the leveling instrument
