Abstract
The utility model relates to a level bar, which comprises a rectangular triangular ruler. A measuring mechanism used for measuring verticality is arranged on a rectangular edge of the rectangular triangular ruler. Because the utility model adopts the structural characteristic and a right angle side of the rectangular triangular ruler can be vertically leaned on the surface of a measured object when the level bar is used, the inclination of the measured object can be conveniently and directly read from scales carved on the pipe wall of a leveling bead or a guiding groove and a driving plate with scales. The utility model has the advantages of simple structure and low cost, and the level bar is favorable for carryover.
Description
The utility model relates to a kind of construction account instrument, relates to a kind of surveyor's staff specifically.
The instrument of measuring verticality and levelness is nothing more than spirit-leveling instrument and transit two big classes at present, and transit involves great expense, and the surface measurement for ganoid plane or closely little target such as circular cone, cylindrical side has underemployed sensation very much; And existing surveyor's staff is with the ruler of horizontal pearl of tubulose or discoid horizontal pearl always, and whether its surface that only can judge testee level or vertical, can not measure the number of degrees of deviation.
The purpose of this utility model provides a kind of surveyor's staff with regard to being at above-mentioned existing in prior technology deficiency, and it is not only simple in structure, is beneficial to carry, and is simultaneously cheap, and manufacturing cost only is equivalent to 1/20th of transit.
The purpose of this utility model can realize by following technical measures:
The utility model comprises a right angle set square, and described drawing square one right-angle side is provided with a measuring mechanism that is used for the measuring vertical degree.
Described measuring mechanism is an arcuation level pearl and the scale that is engraved on this arcuation level pearl tube wall.Also can adopt a straight pipe type level pearl, the end of described straight pipe type level pearl and the hypotenuse of described drawing square are hinged, and the other end is placed in the guide groove that has scale on described drawing square one right-angle side; On another right-angle side of described drawing square, be provided with a set screw and be sleeved on dial on the described set screw, and be arranged on the scale on the described dial near a side of described guide groove.
Advantage of the present utility model just is to be provided with a measuring mechanism of being made up of an arcuation level pearl or a straight pipe type level pearl that is used for the measuring vertical degree by drawing square one right-angle side, during use, drawing square one right-angle side is vertically leaned against by the side object surfaces, thereby can be easily from being engraved on the scale on the described level pearl tube wall, or on the guide groove that has scale and dial, directly read by the degree of tilt of side object, and the utility model is simple in structure, cheap, be beneficial to and carry.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the front view of the utility model embodiment 1.
Fig. 2 implements the front view of side 2 for the utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
Embodiment 1: as shown in Figure 1, the utility model comprises a right angle set square, described drawing square one right-angle side 1 is provided with a measuring mechanism that is used for the measuring vertical degree, and described measuring mechanism is an arcuation level pearl 2 and is engraved in scale on these arcuation level pearl 2 tube walls.
Embodiment 2: as shown in Figure 2, the utility model comprises a right angle set square, described drawing square one right-angle side 1 is provided with a measuring mechanism that is used for the measuring vertical degree, described measuring mechanism is a straight pipe type level pearl 3, the end of described straight pipe type level pearl 3 and the hypotenuse 4 of described drawing square are hinged, and the other end is placed in the guide groove that has scale 6 on described drawing square one right-angle side 5; On another right-angle side 7 of described drawing square, be provided with a set screw 8 and be sleeved on dial 9 on the described set screw 8, and be arranged on the scale on the described dial 9 near a side of described guide groove 6.
