Rapid level gauge level-djusting structure

Abstract

The invention discloses a rapid level gauge level-djusting structure. The structure comprises a base, a level gauge body and a connecting bottom plate, wherein a tubular level, a circular level and a tilting screw are arranged on the level gauge 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 fit 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 on at the parts, at the upper and lower sides of the floating block, of the oscillating rod respectively; a control hammer is arranged at the lower end of the oscillating rod; a counterweight screw horizontally arranged from left to right is also arranged at the lower part of the oscillating rod; balancing weights are respectively connected at the left and right sides of the counterweight screw by threads; 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 level gauge level-djusting structure can rapidly complete a levelness initial adjustment procedure and has higher levelness when a sight axis works.

Description

technical field [0001] The invention relates to a level, in particular to a leveling structure used for adjusting the collimation axis to a horizontal state when the level is measured. 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...

Problems solved by technology

[0003] An object of the present invention is to provide an easy-to-adjust leveling structure for solving the cumbersome initial adjustment process existing in the existing optical level adjustment structure, which can not only quickly and conveniently complete the leveling initial adjustment program, At the same time, it is beneficial to reduce the requirements for measuring personnel

[0004] Another object of the present invention is to solve the problem that the collimation axis of the telescope in the existing optical level adjustment structure is prone to large errors during level adjustment, thus affecting the measurement accuracy of the level, and to provide a quick level adjustment of the level Structure, which can make the telescope collimation axis of the leveling instrument have a higher 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
