Abstract

The utility model relates to a self-supporting type leveling rod, comprising a rod body, a rotating device and a rod pad, wherein the rod body is arranged on a sleeve of the rotating device which is assembled on the rod pad, a circular level bubble and scale marks, the rod body can optionally rotate, the rotating device can rotate forwards and backwards (alignment) and can ensure an unchanged center point, the rotating device is provided with a sleeve and an elastic screw, the center of the rod pad is provided with a square hole, the side surface of the rod pad is provided with an elastic screw, and a base is provided with four foot rests. The self-supporting type leveling rod has simple design and structure, is easy to process and produce, is convenient to use, can not be held up by a measurer, can retain stabilization and verticality by self after being slightly debugged and fixed, solve the problem of manual control of the verticality of the leveling rod, ensure measuring accuracy, reduce the working strength of the measurer and relieve the manual control difficulty of the fixation and the verticality of the leveling rod.

Description

The self-supporting levelling pole
Technical field
The utility model relates to a kind of self-supporting levelling pole, specifically, relates to a kind of homeostasis, and fulcrum is constant, does not need the hand steered levelling pole of survey crew.
Background technology
Existing levelling pole mainly contains following several: 1, the demanding fourth class of measuring accuracy is to 3 meters used levelling poles of primary levelling; 2, the stretchable tower levelling pole of general measure accuracy requirement; 3, the hinged folding levelling pole of general measure accuracy requirement.All attach air level on these three kinds of levelling poles, survey crew needs hand steered levelling pole, must guarantee that levelling pole does not rock all around when measuring, and also the very important person is placed in the middle for the air level on the control levelling pole, could guarantee that levelling pole is vertical.Yet, to measure in the operation, the hand-held levelling pole of staff is hurried back and forth in each measurement point, and itself is just very arduous, and also the very important person causes reading inaccurate for control levelling pole double swerve and vertically being not easy really not; Add on same measurement point and to rotate blade again during reading, skew has taken place in central point, causes reading more inaccurate, especially in closed path is measured, causes degree of accuracy not reach, and therefore, is difficult to guarantee the accuracy of measuring.
Summary of the invention
The purpose of this utility model is a kind of self-supporting levelling pole that provides in order to address the above problem, and this levelling pole does not need survey crew hand steered, and debugging a little just can self keep stable with vertical.
The technical scheme that the utility model provides is: comprise blade, whirligig and foot pin; Blade is placed on the whirligig sleeve, and whirligig is fitted on the foot pin.A round air level and scale mark are set on the blade, and blade can rotate arbitrarily, whirligig also can before and after (over against) rotate, and can guarantee that central point is constant; A sleeve and a parbuckle screw are arranged on this wheelwork; There is a square opening in foot pin central authorities, and there is a parbuckle screw side, and base is provided with four foot rests.
The beneficial effects of the utility model: simple in structure, processing easily; Easy to use, it is hand steered to need not survey crew, can self keep stable with vertical, and when measuring point rotated blade, central point was constant, has solved the vertical difficulty of artificial control levelling pole, has guaranteed measuring accuracy; Alleviate the working strength of survey crew simultaneously, removed the difficulty of artificial control levelling pole vertical fixing.
Description of drawings
Be to be further described with specific embodiment in conjunction with the accompanying drawings below.
Fig. 1: be structural representation of the present utility model.
Among the figure: 1. blade, 2. justify air level, 3. scale mark, 4. whirligig, 5. parbuckle screw, 6. sleeve, 7. foot pin, 8. square opening, 9. parbuckle screw, 10. foot rest.
Embodiment
Referring to Fig. 1, the utility model comprises blade 1, whirligig 4 and foot pin 7, and blade 1 comprises round air level 2 and scale mark 3, and whirligig 4 comprises parbuckle screw 5 and sleeve 6, and foot pin 7 comprises square opening 8, parbuckle screw 9 and foot rest 10.During use, blade 1 is inserted in the sleeve 6, regulate fixedly blade 1 of parbuckle screw 5, regulate parbuckle screw 9 scalable whirligigs 4, foot rest 10 can be used for mountain region and broken terrain.
