A protractor is fixed arranged on the landing leg, a motion bar used to aim at a point to be measured is hinged at the center of the protractor, and the hinge location of the motion lever is further provided with a lock nut used to fasten the motion lever. The protractor slope scale has the advantages of being reasonable in design, simple in structure, low in construction cost, convenient to carry, and capable of being adapted to slope measurement of various complicated construction sites.
Description
Technical field
The utility model relates to a kind of angulation type grade rod.
Background technology
In the engineering construction process, inevitably will use survey instrument, and grade rod is a kind of survey instrument commonly used relatively, at present, those skilled in the art have also designed many grade rods according to practical application.For example: number of patent application is a kind of measurement level of 200920010114.9, vertical, oblique angle grade rod, comprises the chi main body, liquid housing, translucent cover, liquid; The translucent cover angle line is provided with the angle index line on corresponding liquid housing on the perpendicular muscle of chi main body, and corresponding liquid housing place is provided with folding at chi main body lower frame edge, adorns a reflection picture frame in the folding; Catoptron of insert above the reflection picture frame, a vertical miter angle plate is established at the chi main body lower frame edge below the reflection picture frame, and upper ledge is established stay hook; Be provided with the ruler scale mark at chi main body opposite side lower frame edge; Though that this grade rod has is simple in structure, cost is low, reading is directly perceived, advantage easy to use; But because it relies on chi main body to contact with tested surface to realize and measures, when surface of contact was smooth inadequately, the precision of its measurement will be affected.
Summary of the invention
The utility model provides a kind of angulation type grade rod, and this grade rod is reasonable in design, and is simple in structure, cheap, easy to carry, can adapt to the on-the-spot slope measuring of various complicated construction.
The technical scheme of the utility model is: a kind of angulation type grade rod; It is characterized in that: comprise supporting leg; Said supporting leg is provided with the plumb bob that is used to correct the supporting leg verticality; Be set with a protractor on the said supporting leg, the center of said protractor also be hinged with one be used to aim at the measured point motion bar.
As a kind of preferable design proposal, the central point of said protractor is positioned on the intersection point of supporting leg and motion bar.
As a kind of preferable design proposal, the hinged place of said motion bar also is provided with the set nut that is used for its locking positioning.
As a kind of preferable design proposal, said protractor is 90 ° of angle protractors, 180 ° of angle protractors or 360 ° of angle protractors.
As a kind of preferable design proposal, the zero graduation line of said protractor and the center line parallel axes of supporting leg.
As a kind of preferable design proposal, the point of fixity of said plumb bob is positioned at the center of protractor.
As a kind of preferable design proposal, on the other end of said supporting leg also correspondence be provided with the tip.
The utility model utilizes parallelogram principle to carry out slope measuring; Suppose that promptly this angulation type grade rod is positioned at the end, slope, and motion bar hinged place distance overhead is L, we can plug in the mark post that length is L on the top, slope so; Then the extended line direction of motion bar is aimed at the top of mark post; And be fixed, then through on protractor, reading the number of degrees, the gradient just can be read in the back of converting; Yet we can also directly be marked on the good value of slope that converts on the protractor, so that the number of degrees.
The advantage of the utility model is: this grade rod is reasonable in design, and is simple in structure, cheap, easy to carry, can adapt to the on-the-spot slope measuring of various complicated construction.
