Description
Technical field
The utility model relates to a kind of high precision indium steel ruler with outer-enwraped type telescopic spring supporting leg, belongs to surveying and mapping tool technical field.
Background technology
Since the nineties in 20th century, First electronic level was born, it has, and precision is high, test the speed fast, simple operation and other advantages, its measurement of higher degree accurately becomes the important means of measurement of the level, at present, be widely used in route leveling, tunnel monitoring measurement, building operation and bridge construction etc.Indium steel ruler is one measurement levelling pole first-selected during high-precision electronic spirit-leveling instrument is measured, and indium steel ruler indium steel band makes the matrix of delineation reading, and delineation is very tight, has the advantages that thermal expansivity is little, precision is high, be not substantially subject to extraneous thermal effect.
In high-precision leveling process, indium steel ruler is vertically put most important, and it directly affects the accuracy of measuring.When gauge point number is many, Measuring Time is long, special in the environment that the wind speed such as mountain area cheuch, river, ocean are larger, person easily produces work fatigue to hold up chi, affect measuring accuracy, and usually cause repetition measurement to be checked, waste the activity duration of manpower and preciousness in the process, this is a problem needing to solve.Therefore, design the fatigue that a kind of high precision indium steel ruler with outer-enwraped type telescopic spring supporting leg not only can alleviate worker, make to measure conveniently, and measurement accuracy also improves greatly.
Utility model content
The utility model, in order to overcome the deficiency of above technology, provides a kind of high precision indium steel ruler with outer-enwraped type telescopic spring supporting leg.
the utility model overcomes the technical scheme that its technical matters adopts:
A kind of high precision indium steel ruler with outer-enwraped type telescopic spring supporting leg, comprise indium steel ruler body, the back side of described indium steel ruler body is provided with telescopic outrigger, described telescopic outrigger comprises sleeve and is sheathed on the pipe in sleeve, the periphery of pipe is provided with spring, the upper end of spring is fixedly connected with the lower end of sleeve, and the lower end of spring is fixedly connected with the lower end of pipe, and the lower end of pipe is provided with leg.
Preferred according to the utility model, the upper end of described sleeve is fixed on indium steel ruler body by hinge.
Preferred according to the utility model, described leg bottom surface is provided with sheet rubber, to increase the friction force of telescopic outrigger and ground.
Preferred according to the utility model, the back side of described indium steel ruler body is also provided with groove, at the end of measurement, leg is put into groove, is easy to carry.
the beneficial effects of the utility model are:
The high precision indium steel ruler of the utility model band outer-enwraped type telescopic spring supporting leg, the telescopic outrigger of band spring is arranged at the indium steel ruler body back side, finely tuned up and down by the dual regulation of external springs, when the person that holds up chi adjusts and keeps indium steel ruler vertical, namely leveling bubble is placed in the middle, to reach accurate measurement, particularly when field wind speed larger on indium steel ruler vertically stable bring affect time, can ensure accurate measurement; Outer-enwraped type telescopic spring supporting leg mainly plays support and stabilization, and when particularly measuring for a long time, the existence of supporting leg can reduce the fatigue of the person that holds up chi.The use of supporting leg improves external condition to the impact of measuring, and ensures measuring accuracy, measurement operating efficiency and accuracy rate are improved greatly, can realize surface that is long-time, extensive area and accurately measure.Structure of the present utility model is simple, easy for installation in addition.
