Description
Technical field
The present invention relates to the high accuracy indium steel ruler of a kind of band outer-enwraped type telescopic spring supporting leg, belong to surveying and mapping tool technical field.
Background technology
Since the First electronic level birth nineties in 20th century, 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 the measurement of the level, at present, it is widely used at aspects such as route leveling, tunnel monitoring measurement, construction and bridge constructions.Indium steel ruler is a kind of measurement levelling rod first-selected during high-precision electronic level gauge is measured, and indium steel ruler indium steel band makees the substrate of delineation reading, and delineation is very tight, has the advantages that thermal coefficient of expansion is little, precision is high, the most free of extraneous thermal effects.
During high-precision leveling, indium steel ruler is vertically put most important, and it directly affects the accuracy of measurement.When measuring point number is many, the measurement time is long, especially in the environment that the wind speed such as mountain area cheuch, river, ocean are bigger, person is easily generated work fatigue to hold up chi, affect certainty of measurement, and frequently result in repetition measurement inspection, wasting the activity duration of manpower and preciousness in the process, this is a problem needing to solve.Therefore, the high accuracy indium steel ruler designing a kind of band outer-enwraped type telescopic spring supporting leg not only can alleviate the fatigue of worker so that it is convenient to measure, and measurement accuracy is also greatly improved.
Summary of the invention
The present invention is in order to overcome the deficiency of above technology, it is provided that the high accuracy indium steel ruler of a kind of band outer-enwraped type telescopic spring supporting leg.
The present invention overcomes its technical problem be the technical scheme is that
A kind of high accuracy indium steel ruler of band outer-enwraped type telescopic spring supporting leg, including indium steel ruler body, the back side of described indium steel ruler body is provided with telescopic outrigger, described telescopic outrigger includes sleeve and the pipe being sheathed in sleeve, the periphery of pipe is provided with spring, the upper end of spring is fixing with the lower end of sleeve to be connected, and the lower end of spring is fixing with the lower end of pipe to be connected, and the lower end of pipe is provided with leg.
According to currently preferred, the upper end of described sleeve is fixed on indium steel ruler body by hinge.
According to currently preferred, described leg bottom surface is provided with sheet rubber, to increase the frictional force of telescopic outrigger and ground.
According to currently preferred, the back side of described indium steel ruler body is additionally provided with groove, at the end of measuring, leg is put into groove, it is simple to carry.
The invention has the beneficial effects as follows:
The high accuracy indium steel ruler of band outer-enwraped type telescopic spring supporting leg of the present invention, 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, i.e. level(l)ing bubble is placed in the middle, to reach accurately to measure, particularly when indium steel ruler is the most stably brought relatively greatly and affects by field wind speed, can guarantee that accurately measurement；Outer-enwraped type telescopic spring supporting leg primarily serves support and Stabilization, and when measuring the most 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 the external condition impact on measuring, it is ensured that certainty of measurement, makes measurement working performance and accuracy rate be greatly improved, and can realize long-time, the surface of extensive area and accurately measure.The additionally simple in construction, easy for installation of the present invention.
