Abstract

The utility model discloses a horizontal ruler which comprises a ruler body, wherein a dial I is mounted on at least one side surface of the ruler body; a linear pointer I is mounted on the dial I; a central rotary shaft of the linear pointer I coincides with the center of the dial I; a plumb block for keeping the linear pointer I horizontal all the time is arranged on the central rotary shaft. When a measured object is measured, the ruler body leans on the measured object, and the included angle between the measured object and a horizontal plane can be measured by virtue of cooperation of the linear pointer I and the dial I and can be directly read out from the dial I, so that the measured object can be conveniently measured by an operator and the measurement accuracy and the measurement precision are ensured. The horizontal ruler is simple in structure and convenient to operate, improves the measurement accuracy and precision and is suitable for leveling and alignment of buildings or equipment on building sites.

Description

A kind of surveyor's staff

Technical field

The utility model relates to a kind of instrument, particularly a kind of surveyor's staff.

Background technology

At present, when building ground buildings or equipment levelling capturing, all need usage level chi, and existing surveyor's staff is all provided with three glass tubes that are full of liquid, in each glass tube, all there is a bubble, wherein the glass tube of horizontally set is used for measuring surface level, vertical glass is effective measures vertical plane, another one is used for measuring 45 °, gauger need to observe bubble whether in the centre position of glass tube with eyes, utilize eyes to carry out to measured object the error that levelling easily causes measurement, accuracy is lower; On the other hand, existing surveyor's staff can only be measured the angle of the specific positions such as 0,45 °, 90 °, 180 °, and the degree of accuracy of its measurement is lower, has all brought great inconvenience to operating personnel's actual measurement and levelling capturing.

Summary of the invention

The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of surveyor's staff that improves accuracy of measurement and degree of accuracy.

The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of surveyor's staff, be characterized in: comprise chi body, on at least one side of chi body, scale I is housed, yi word pattern pointer I is installed in scale I, the central rotating shaft of yi word pattern pointer I overlaps with the center of circle of scale I, is provided with the vertical piece that remains yi word pattern pointer I level on central rotating shaft.

The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, on another side of chi body, be provided with and the symmetrically arranged scale II of scale I, the yi word pattern pointer II with the coaxial setting of yi word pattern pointer I is installed in scale II.

The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the measurement range of described scale I and scale II is 0-360 °, and the minimum scale value of scale is 1 °.

Compared with prior art, the utility model is when measuring testee, chi body is leaned against on testee, utilize the angle that can measure testee and surface level that coordinates of yi word pattern pointer I and scale I, its angle value can directly be read from scale I, both facilitated operating personnel's measurement, the accuracy and precision while having guaranteed again to measure.The utility model is simple in structure, easy to operate, has improved accuracy and the accuracy measured, during applicable to building ground buildings or equipment levelling capturing, uses.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

A kind of surveyor's staff, comprise chi body 1, on at least one side of chi body 1, scale I 2 is housed, yi word pattern pointer I 3 is installed in scale I 2, the central rotating shaft 4 of yi word pattern pointer I 3 overlaps with the center of circle of scale I 2, is provided with the vertical piece that remains yi word pattern pointer I 3 levels on central rotating shaft 4.On another side of chi body, be provided with and the symmetrically arranged scale II of scale I 2, the yi word pattern pointer II with the 3 coaxial settings of yi word pattern pointer I is installed in scale II; The measurement range of described scale I 2 and scale II is 0-360 °, and the minimum scale value of scale is 1 °.Described chi body 1 is rectangular parallelepiped, front and back at chi body 1 is symmetrically installed with respectively with chi axon to the scale I be arrangeding in parallel and scale II, scale I and scale II are arranged on respectively the center position of chi body front and back, can handled easily personnel measure like this, utilize the vertical piece guaranteeing all the time with yi word pattern pointer I and yi word pattern pointer II level, measure the angle of inclination of testee and surface level, because the minimum scale value of scale I and scale II is 1 °, improved the accuracy of measuring.In the time of need to measuring the height of buildings in building ground, can use this equipment to measure, one end of chi body is pointed to the top of buildings, other end directed towards ground, read the angle between buildings top and surface level, recycling tape measure chi body directed towards ground one end, to the horizontal range of buildings, finally just can calculate the height of tested buildings by trigonometric function.Can also be for checking the flatness of various lathes and other equipment guide rails, and when the installation of equipment, line, construction, play the whether effect of level of measured object of measuring.

Claims

1. a surveyor's staff, it is characterized in that: comprise chi body, on at least one side of chi body, scale I is housed, yi word pattern pointer I is installed in scale I, the central rotating shaft of yi word pattern pointer I overlaps with the center of circle of scale I, is provided with the vertical piece that remains yi word pattern pointer I level on central rotating shaft.

2. surveyor's staff according to claim 1, is characterized in that: on another side of chi body, be provided with and the symmetrically arranged scale II of scale I, the yi word pattern pointer II with the coaxial setting of yi word pattern pointer I is installed in scale II.

3. surveyor's staff according to claim 2, is characterized in that: the measurement range of described scale I and scale II is 0-360 °, and the minimum scale value of scale is 1 °.
