The specific embodiment
The utility model in conjunction with specific embodiments, is described in detail as follows with reference to accompanying drawing:
Embodiment 1
As shown in Figure 1, chassis 1 is along being circumferentially with chassis groove 2; The neighboring on chassis 1 is provided with dial 3, and dial 3 is along circumferentially being provided with evenly divided hole 4 to card, and evenly divided hole 4 is formed a plurality of locus circles to the dial center of circle by different radii; The center on chassis 1 is provided with the mandrel vertical with the chassis 5, is set with axle sleeve I6 and axle sleeve II7 on the mandrel 5 successively, and axle sleeve I and axle sleeve II are along being circumferentially with the axle sleeve groove; Be connected separation structures such as three groups on axle sleeve I and the axle sleeve II, the described separation structure that waits is, an end of connecting plate 8 is fixed on the axle sleeve I, circumferentially rotates along the axle sleeve groove of axle sleeve I, the other end of connecting plate 8 is connected with an end of bus bar plate 9, and the other end of bus bar plate 9 is provided with pointer 10; The bottom of bus bar plate 9 is provided with bracing frame 11, and bracing frame 11 is mobile in chassis groove 2; One end of five equilibrium plate 12 is fixed on the axle sleeve II, circumferentially rotates along the axle sleeve groove of axle sleeve II, and the other end of five equilibrium plate 12 passes bus bar plate 9.
One side of described bus bar plate 9 is provided with groove 13, and bus bar plate and five equilibrium plate cross facet are provided with groove 14; Bus bar plate and five equilibrium plate are fixing by packing ring, bolt 15 and rotation nut 16, and bolt passes groove 13; Be connected with five equilibrium frame 17 on the bolt, the five equilibrium frame is provided with scriber 18; In the separation structures such as three groups, scriber equates apart from the interval of waiting branch frame riser 19.Scriber 18 and pointer 10 all can move up and down.
In the separation structures such as described three groups, the bolt in two separation structures such as the outside adopts prismatic, and the bolt in the separation structures such as centre adopts cylindrical; The angular range of two separation structures such as outside formations is between the 0-180 degree.
Be equipped with bearing arrangement on described axle sleeve I and the axle sleeve II, axle sleeve I and axle sleeve II form by bearing arrangement and mandrel and move up and down.
Operation principle of the present utility model and process be, three scalable movements of maternal instinct plate, and enlarge the radius of itself and mandrel; Two outside bus bar plates are fixed on chassis 90 degree or the 180 degree scale holes by bracing frame, can circumferentially move; The intermediate bus bar plate rotates by mandrel Upper shaft sleeve I groove; Pointer on the bus bar plate in the bus bar plate of the outside inserts in the scale groove, and dial can move and rotate along with bus bar plate, and the scale on the different circumference from then on bus bar plate begins the evenly divided number.
Three five equilibrium plates can move up and down in the bus bar plate groove, and wherein two outsides wait the branch plate to decide the angle at 90 degree or 180 degree, and branch plates such as centre can rotate along axle sleeve II groove; The infall of five equilibrium plate and bus bar plate is three points treating on the circumference in equal parts; Scriber on the branch framves such as centre can have trace mobile in order to draw the five equilibrium mark; Though scriber is not at the infall of five equilibrium plate and bus bar plate, but because three scribers equate apart from the distance that waits branch frame riser, and infall is that radius R equates with the mandrel distance, the equivalent of triangle that three bus bar plates and mandrel surround, so treat also congruence of triangle that Equal round and three bus bar plates surround, namely radius is in same circumference.
During operation, during mobile bus bar plate gradual change, the angle of three bus bar plates and mandrel enlarges thereupon and dwindles, and bus bar plate pointer total energy in the outside is aimed at integer position on the dial; In order to raise the efficiency, can make dial outside scale intensive; If wholecircle is wanted seven five equilibriums, the right side bus bar plate pointer among the figure moves on to seven integer position, left side bus bar plate pointer and seven parts of scales of right side pointer grip hold arc; Because five equilibrium plate control two outsides bus bar plate and five equilibrium plate infall and mandrel intersection point line angle keep 90 degree or 180 degree, treat the five equilibrium of Equal round like this, just become the five equilibrium to 90 degree or 180 degree, namely with reference to contrast 90 degree or 180 degree five equilibriums, and the five equilibrium number of degrees are than therefore becoming the five equilibrium portion rate, as seven five equilibriums, the five equilibrium number of degrees compare=treat that the five equilibrium number of degrees/preset are with reference to the contrast number of degrees=(360/7)/(360/4)=4/7 branch portion rates such as () wholecircles, be branch ratios such as wholecircle, such 1/7,360/7, become the five equilibrium umber ratio with reference to 90 degree or 180 degree.In five equilibrium umber ratio, denominator is branch umbers such as wholecircle, simultaneously again because denominator is with reference to the contrast number of degrees, remaining with reference to the folded scale umbers of contrast two of number of degrees outsides pointer so branch umbers such as wholecircle place, then is 2 or 4 or the angle isodisperse with reference to the contrast number of degrees at the five equilibrium umber of wholecircle; Aim at and fixedly behind the evenly divided umber at three pointers, begin to move up and down the five equilibrium plate, make three scriber perpendicular alignmnets treat Equal round and fixing, at this moment Zhong Jian scriber and the left side scriber angle on the taper seat that with the mandrel is intersection point, be exactly one of branch umber such as wholecircle, middle scriber is at the band circumference in equal parts five equilibrium mark that draws.If a five equilibrium angle, then line left side scriber and middle scriber and 3 of mandrel intersection points get final product.
For the fixing angle of five equilibrium total angle, as aliquot, be converted to branch umbers such as wholecircle, bisecting method is the same, for unknown angle or be difficult to angle or the aliquant angle accurately measured; Can wait two outsides of control contrast reference angle one of branch plate to become and can rotate along mandrel, angle be for treating sub-multiple angle, for this reason, outside scriber refers on the both sides for the treatment of sub-multiple angle, treat that sub-multiple angle thinks several parts of five equilibriums, the right side pointer is just aimed at several parts of scales, and middle pointer is counted aligning a copy of it from the left side.
Be the operating space, the molecule denominator on the geometric ratio umber ratio can be with doubly increasing, and as 2/7=4/14, each pointer respective aligned enlarges on the umber of multiple.
As shown in Figure 2, M/N=L θ/L β=θ/β=m/n, namely the five equilibrium of conical bottom circle also is the five equilibrium to its conic section circle.
Angle between the bus bar plate is used for increasing or branch umber such as minimizing, and the five equilibrium plate is used for when the five equilibrium umber changes, and maintenance treats that sub-multiple angle is constant.Two outside bus bar plate angles can be changed to and treat five equilibrium number of degrees angle.
Protection domain of the present utility model is as the criterion with claim, not limited by specific embodiment.
