Said weight is made up of iron screw and screw cap, is connected fixing with the screw that the balancing point bottom is provided with.
Said index dial and balancing point are fixed in the square drain pan, fixed panel on the drain pan.
The method of application of described dial type angle square may further comprise the steps:
(1) will fill up chi is placed on the plane of desire measurement;
(2), the one side and the pad chi surface of said dial type angle square is adjacent to according to the direction that takes measurement of an angle;
(3) treat that balancing point is static, angle is the angle of required measurement between the zero graduation line of interior index dial and the pointer direction.
When measuring the gradient, the base of said dial type angle square or top margin and pad chi surface are adjacent to.
When measuring perpendicularity deviation, the side of said dial type angle square is adjacent to pad chi surface.
Beneficial effect of the present invention:
The present invention can measure any slope angle and the angulation that is used for check level, vertical plane by precise and high efficiency at work progress when inspecting for acceptance.This dial type angle square can be estimated and reads 0.1 °, has satisfied the construction needs; Of many uses, can measure any slope angle, comprise and check surface level and vertical plane; This product is light and handy, and is with low cost, accurately and reliably, is easy to carry, and service efficiency is high.

Embodiment
Below in conjunction with Figure of description the present invention is described further.
Shown in Fig. 1-3; A kind of dial type angle square; Comprise index dial and with its fixing balancing point, it is characterized in that: index dial 1 and EXT scale dish 2 in described index dial comprises, said in index dial 1 be fixed on EXT scale dish 2 central authorities; It is coniform that interior index dial 1 is flat-top, forms transition structure with a slope between interior index dial 1 and the EXT scale dish 2; Gradient design between inside and outside index dial can effectively not avoid the use of the accidental error that person's sight line out of plumb index dial brings.Index dial 1 summit scale marker is 0 ° in said, and the minimum point scale marker is 180 °; Said EXT scale dish 2 summit scale markers are 180 °, and the minimum point scale marker is 0 °; Interior index dial 1 is consistent corresponding with scale between the EXT scale dish 2; And the scale marker intersection is corresponding; Put from the summit on earth in for example interior index dial 1 left side is 0-180 ° of sign; And to put on earth from the summit be 180-0 ° of sign in EXT scale dish 1 left side, need not convert and conveniently read the angle value of any gradient, equally also can check level and verticality.The scale of index dial and EXT scale dish was all once serve as the sign unit in said, and this dial plate protractor can be estimated and reads 0.1 °, satisfied needs of constructing.
A central rotating shaft is installed at interior index dial 1 center, connects balancing point 3 on the central rotating shaft; Said balancing point 3 integral body are ellipticity, and balancing point 3 tops are the closed up-narrow and down-wide structure 6 of hollow, place, closed up-narrow and down-wide structure summit fixed pointers 4, and balancing point 3 bottoms are weight 5 fixedly.Said balancing point 3 tops are the closed up-narrow and down-wide structure 6 of hollow, closed triangle structure for example, and it compares the flexural deformation that effective minimizing temperature and mechanical friction produce balancing point with previous pendulum model structure, and top pointer verticality does not receive the influence of balancing point.
Said weight 5 is made up of iron screw and screw cap, and the screw that bottom balancing point, is provided with is connected fixing, and this structure is installed, convenient disassembly, the convenient adjusting of size.Said index dial and balancing point 3 are fixed in the square drain pan 11, and fixed panel 12 on the drain pan.Balancing point 3 is connected on the index dial through the balancing point fixture.The method of application of described dial type angle square may further comprise the steps:
