Description
Technical field
The present invention relates to a kind of high accuracy indium steel ruler with built-in spring rotary regulating telescopic outrigger, belong to surveying and mapping tool technical field.
Background technology
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.At present, it is widely used at aspects such as route leveling, tunnel monitoring measurement, construction and bridge constructions.
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, designing a kind of high accuracy indium steel ruler with built-in spring rotary regulating telescopic outrigger and not only can alleviate the fatigue of worker, it is convenient to measure, and the raising that measurement accuracy is the biggest.
Summary of the invention
The present invention is in order to overcome the deficiency of above technology, it is provided that a kind of high accuracy indium steel ruler with built-in spring rotary regulating telescopic outrigger.
The present invention overcomes its technical problem be the technical scheme is that
A kind of high accuracy indium steel ruler with built-in spring rotary regulating telescopic outrigger, including indium steel ruler body, the back side of described indium steel ruler body is provided with telescopic outrigger, described telescopic outrigger includes sleeve, be sheathed in sleeve the first pipe and the second pipe being sheathed in the first pipe, it is provided with spring in described sleeve, the upper end of spring is fixing with the upper end of sleeve to be connected, the lower end of spring is fixing with the upper end of the first pipe to be connected, the inwall of described first pipe and the outer wall of the second pipe are provided with the screw thread matched, and the lower end of the second 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:
nullThe high accuracy indium steel ruler with built-in spring rotary regulating telescopic outrigger of the present invention，Telescopic outrigger is arranged at the indium steel ruler body back side，The inwall of the first pipe and the outer wall of the second pipe are provided with the screw thread matched，By rotating the first pipe and the length of the second pipe regulation telescopic outrigger，Optimum position during to reach to hold up chi，Thus stability when strengthening helping indium steel ruler，And it is provided with spring in sleeve，Telescopic outrigger can be finely tuned by the dual regulation of spring up and down，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，When measuring the most for a long time，The telescopic outrigger of the present invention can reduce the fatigue of the person that holds up chi，This use by screw thread rotation and spring makes to measure working performance and accuracy rate is greatly improved，Can realize long-time、The surface of extensive area is accurately measured.The additionally simple in construction, easy for installation of the present invention.
