Abstract
The invention belongs to the technical field of measuring tools and provides a level bar. The level bar is mainly characterized in that adjusting frames are respectively arranged at the two ends of a level bar body, the adjusting frames are in slide connection with the level bar body, the sliding direction of each adjusting frame is vertical to the axial line of the level bar body, scale values are respectively arranged on the adjusting frames along the sliding directions of the adjusting frames, and a footing piece is arranged at the bottom end of each adjusting frame; an adjusting mechanism is further arranged between each adjusting frame and the level bar body, each adjusting mechanism comprises a pulling plate, a gear disc and a gear rack, the pulling plate and the gear disc are coaxially fixed and are fixed on the level bar body through rotating shafts, each gear rack is fixed on the corresponding adjusting frame, and each gear disc is engaged with the corresponding gear rack; and an antiskid screw is arranged between each adjusting frame and the level bar, and an antiskid piece is arranged at the tail end of each antiskid screw. Compared with the prior art, the level bar provided by the invention can be used for measuring the horizontal height difference between the two sides of an object and more accurately adjusting the object according to data to ensure a relatively accurate levelness of the object.
Description
Technical field
The invention belongs to the survey instrument technical field, particularly a kind of surveyor's staff.
Background technology
Surveyor's staff is for the survey instrument that the level of object, vertical or 45 degree states is detected centering, can measure the levelness of object very easily.Existing surveyor's staff is made up of chi body and bubble pipe.During use, surveyor's staff is placed on the testee, which side bubble in the bubble pipe is partial to, represent that then which side is higher, namely need to reduce the height of this side, or heighten the height of opposition side, make bubble be adjusted to the center of bubble pipe, just represent testee both sides level height difference close to zero, both testee was level in the direction along the chi body.This surveyor's staff is by the observation bubble position, adjust the horizontality that the mode of dwindling testee both sides level height difference is come the centering object gradually, when needs are accurately known the level height difference value, because this surveyor's staff can't record before the adjustment and the level height value after adjusting, just can't calculate the level height difference of object both sides, be merely able to estimate this numerical value according to range estimation, use inconvenient.
Summary of the invention
The present invention take for its technical matters of solution technical scheme be, design a kind of surveyor's staff, its structure comprises: chi body and bubble pipe; Wherein, be respectively equipped with adjusting bracket at the two ends of chi body, be slidingly connected between adjusting bracket and the chi body, the glide direction of adjusting bracket is perpendicular to the axis of chi body, and the direction along its slip on adjusting bracket is provided with scale value, is provided with footing piece in the adjusting bracket bottom; Also be provided with governor motion between adjusting bracket and chi body, this governor motion comprises dial, toothed disc and gear bar, and dial is fixed and is fixed on the chi body by rotating shaft with toothed disc is coaxial, and the gear bar is fixed on the adjusting bracket, and toothed disc is meshed with the gear bar; Also between adjusting bracket and chi body, be provided with anti-skid screw, be provided with anti-slide plate at the tail end of anti-skid screw;
Further, be provided with the anticreep convex edge in the upper end of described adjusting bracket;
Further, the bottom of described footing piece is provided with magnetic strips.
After this novel surveyor's staff adopts technique scheme, can record the level height difference value of object by following steps, 1. allow the magnetic strips of footing piece be adsorbed on body surface, unclamp both hands by surveyor's staff from line stabilization; 2. regulate anti-skid screw and make anti-slide plate be close to adjusting bracket, anti-slide plate jam-packed adjusting bracket can not freely fall it; 3. rotate low distolateral dial, dial and toothed disc rotate together, slide up and down thereby toothed disc drives adjusting bracket by the gear bar, and the scale value on the adjusting bracket also changes thereupon, and this process finishes when bubble is positioned at the center of bubble pipe; 4. read the data of scale value, this numerical value is exactly the level height difference value at testee two ends.Compared with prior art, the present invention can measure the level height difference value of object both sides, can adjust object more accurately according to these data, makes the levelness of object more accurate.
