Description
Technical field
The utility model relates to a kind of high precision indium steel ruler with built-in spring rotary regulating telescopic outrigger, belongs to surveying and mapping tool technical field.
Background technology
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.At present, be widely used in route leveling, tunnel monitoring measurement, building operation and bridge construction etc.
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 built-in spring rotary regulating telescopic outrigger not only can alleviate worker, it is convenient to measure, and the raising that measurement accuracy is also larger.
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 built-in spring rotary regulating telescopic outrigger.
the utility model overcomes the technical scheme that its technical matters adopts:
A kind of high precision indium steel ruler with built-in spring rotary regulating telescopic outrigger, comprise indium steel ruler body, the back side of described indium steel ruler body is provided with telescopic outrigger, the second pipe that described telescopic outrigger comprises sleeve, is sheathed on the first pipe in sleeve and is sheathed in the first pipe, spring is provided with in described sleeve, the upper end of spring is fixedly connected with the upper end of sleeve, the lower end of spring is fixedly connected with the upper end of the first pipe, 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.
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 band of the present utility model built-in spring rotary regulating telescopic outrigger, 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 length of the first pipe and the second pipe adjustment telescopic outrigger, with reach hold up chi time optimum position, thus the stability strengthened when helping indium steel ruler, and be provided with spring in sleeve, the dual regulation of spring can be finely tuned up and down to telescopic outrigger, 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, when particularly measuring for a long time, the fatigue of telescopic outrigger of the present utility model can reduce to hold up chi person, this use by screw thread rotation and spring makes measurement operating efficiency and accuracy rate greatly improve, can realize long-time, the surface of extensive area is accurately measured.Structure of the present utility model is simple, easy for installation in addition.
