Embodiment
Below in conjunction with Figure of description, the invention will be further described.
As Figure 1-3, a kind of dial plate type protractor, the balancing point comprising index dial and fix with it, it is characterized in that: described index dial comprises interior index dial 1 and EXT scale dish 2, described interior index dial 1 is fixed on EXT scale dish 2 central authorities, interior index dial 1, in flattened conical shape, forms transition structure with a slope between interior index dial 1 and EXT scale dish 2; The accidental error that slope design between inside and outside index dial can effectively avoid user's sight line out of plumb index dial to bring.Described interior index dial 1 summit scale marker is 0 °, and minimum point scale marker is 180 °; Described EXT scale dish 2 summit scale marker is 180 °, and minimum point scale marker is 0 °; Interior index dial 1 is consistent corresponding with the scale between EXT scale dish 2, and scale marker intersects corresponding, such as, put on earth from summit on the left of interior index dial 1 is 0-180 ° of mark, and to put on earth from summit on the left of EXT scale dish 1 be 180-0 ° of mark, need not be converted the convenient angle value reading any gradient, equally also can inspection AQL and verticality.The scale of described interior index dial and EXT scale dish is all with once for mark unit, and this dial plate protractor can be estimated and reads 0.1 °, meets the needs of construction.
A central rotating shaft is installed at interior index dial 1 center, central rotating shaft connects balancing point 3; Described balancing point 3 entirety is in ellipticity, and balancing point 3 top is the closed up-narrow and down-wide structure 6 of hollow, and closed up-narrow and down-wide structure summit place fixed pointers 4, fixes weight 5 bottom balancing point 3.Described balancing point 3 top is the closed up-narrow and down-wide structure 6 of hollow, such as closed triangle structure, and it effectively reduces the flexural deformation that temperature and mechanical friction produce balancing point compared with previous pendulum model structure, and Top Of verticality is not subject to the impact of balancing point.
Described weight 5 is made up of iron screw and screw cap, is connected and fixed with the screw be provided with bottom balancing point, this structure installment, convenient disassembly, and size is convenient to be regulated.Described index dial and balancing point 3 are fixed in square drain pan 11, fixed panel 12 on drain pan.Balancing point 3 is connected on index dial by balancing point fixture.The using method of described dial plate type protractor, comprises the following steps:
(1) pad chi 7 is placed in the plane for measuring;
(2) according to the direction taken measurement of an angle, being adjacent to described dial plate type protractor with pad chi 7 surface;
(3) treat that balancing point is static, between the zero graduation line 9 of interior index dial and pointer direction 10, angle is the required angle measured.
When measuring the gradient, the base of described dial plate type protractor or top margin and pad chi 7 surface are adjacent to.
When measuring perpendicularity deviation, the side of described dial plate type protractor is adjacent to pad chi 7 surface.
As shown in Figure 4, when measuring angle of slope, be placed on base on pad chi 7, after the right pendulum of balancing point is static, the angle between the zero graduation line 9 of interior index dial and pointer direction 10, is the required angle [alpha] measured.Equally, as shown in Figure 5, side is rested on pad chi 7, can measure and detect verticality θ.
For measuring conveniently, interior index dial 1 zero graduation numeral adopts eye-catching big font; Dial diameters controls to be advisable at 80mm-120mm.
