Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2 in embodiments of the invention.
As shown in Figure 3, disc structure 100 comprises clutch disk 110, disk cap 120, band hatpin assembly 130 and elastic parts 140.
Protruding hollow round table 110(1 is fixedly connected with) above clutch disk 110, protruding hollow round table 110(1) be provided with screw thread, disk cap 120 is flexibly connected with screw thread, protruding hollow round table 110(1) inside comprises a hollow T stage, hollow T stage vertical section is provided with band hatpin assembly 130, and the cap end of band hatpin assembly 130 is provided with elastic parts 140.
Elastic parts 140 comprises the first spring, second spring of same vertical direction.First spring sticking position is above the second spring bullet, and the first the elastic coefficient is greater than the second the elastic coefficient.Band hatpin assembly 130 is specially a draw point, and this draw point namely, connect the first spring above the cap end of band hatpin assembly 130, connects the second spring below cap end.
As Figure 1-Figure 2, supporting structure 200 comprises the first support 210, second support 220.The side that first support 210 clutch disk structure 100 is stretched out, second support 220 and protruding hollow round table 110(1) underneath side is connected, first support 210 is connected via rotating shaft with clutch disk 110, and can rotate freely above the second support 220 together with clutch disk 110.First support 210 and the second support 220 inside cord intersect on the draw point of clutch disk 100.
First support 210 comprises and is arranged on the first bracket groove 211, second bracket groove 212 in support, secondary chi assembly 213 and the assembly 214 that is slidably connected.
The assembly 214 that is slidably connected comprises the first slide assemblies, the second slide assemblies, and concrete is bolt original paper in the present embodiment.
First bracket groove 211, second bracket groove 212 is positioned at the both sides of the supporting structure 200 of horizontal positioned, and is parallel to each other, and is used as the guide rail of the first slide assemblies, the second slide assemblies respectively.
The groove face of the first bracket groove 211 is provided with a secondary chi assembly 213, and with the parallel laminating of secondary chi assembly 213.As shown in Figure 7, secondary chi assembly 213 is specially a secondary chi, and secondary chi is connected with the first bracket groove 211 via the first slide assemblies, and can stretch back and forth along the first bracket groove 211 direction.
The side of the second bracket groove 212 is connected with the second slide assemblies, and the opposite side of the second bracket groove 212 connects and is connected with clamp structure 300.
Fig. 4 is the structural representation of clamp structure in embodiments of the invention.
As shown in Figure 4, clamp structure 300 comprises the pen cap 310, baffle plate 320, bolt arrangement 330.The pen cap 310 is positioned at the first bracket groove 211, draws circular arc for being inserted in pencil.The side of baffle plate 320 connects the pen cap 310 through the first bracket groove 211, and the opposite side of baffle plate 320 is flexibly connected above-mentioned second slide assemblies.
Second support 220 is specially a main scale, and main scale is provided with groove, and this groove is used as the rail plate of clutch disk 110, and clutch disk 110 can be slidably reciprocated along groove.
Fig. 5 is the top view of dial in embodiments of the invention.
As shown in Figure 5, in the present embodiment, dial 400 covers protruding hollow round table 110(1) on, fit in protruding hollow round table 110(1) circumferential edges.Because the second support 220 and the first support 210 inside cord intersect on the draw point of clutch disk 110, so the second support 220 and the first support 210 inside cord intersecting angle are for treating measuring angle, namely dial 400 is for measuring the number of degrees of angle between the first support 210 and the second support 220.
Fig. 6 is the top view of indicating dial in clutch disk and front view in embodiments of the invention.
In the present embodiment, combination drawing tools 001 also comprises indicating dial 500, and indicating dial 500 coordinates the scale 401 showing and to be aimed at by the pointer 501 of indicating dial 500 in described dial 400 with dial 400.
Specific works particular procedures below in conjunction with illustrated combination drawing tools 001 is described.
As shown in figs. 1-7, when combining drawing tools 001 and being used as compasses, protruding hollow round table 110(1 above clutch disk 110) on be provided with disk cap 120, first turn clockwise disk cap 120, disk cap 120 and protruding hollow round table 110(1) be threaded, now draw point can stretch out, compressing disk cap 120 by manpower makes draw point be fixed on drafting paper circle centre position, then the first support 210 that rotating shaft connects is lifted, and fix the first support 210 and longitudinally lift angle, again pen is put in pen clip, making pen extend out to suitably height to nib falls on paper, horizontally rotate and turn chi, eye alignment nib and draw point are in paper distance, by the position adjustments radius size of slip pen clip at the second sliding tray, measure with main scale again and determine the distance of nib and draw point, i.e. arc radius, after finally confirming distance, the pen cap 310 can tightly be fixed on the first support 210 by tightening nut in pen clip simultaneously, make bowlder and buttress disk cap 120 on the other hand, another Hand supplementary first support 210 moves in a circle.
When being used as fixed length level or vertical line, first support 210, second support 220 relative angle is adjusted to 90 degree or 270 degree, again disk cap 120 is tightened clockwise, now draw point can stretch out, people can make main scale press close to paper or plate face with defeating tight dial 400, intercepts fixed length straight line according to main scale high scale.
Be used as when being in certain angle line segment, angle in the first support 210, second support 220 is gone to required dial 400 angle.In like manner locked by disk cap 120, then released by secondary chi fixing, line drawing two lines inside the first support 210, second support 220, supplement lines to joint with main scale subsequently.
The effect of embodiment and effect
According to combination drawing tools involved in the present invention, because there is a draw point in disc structure, this draw point is used as the compasses center of circle, have and be connected the first support with one end of disc structure by arbor wheel vertical rotary, the clamp structure of slip is provided with in the first support, one-pen is inserted in this clamp structure, can be justified by fixing center of circle pen with rotary, first side face is provided with a secondary chi, the ruler of the second support coordinating supporting structure to comprise, the straight line of certain length can be made, also can cooperatively interact and be T-shaped figure, in addition, disc structure is also provided with dial, the angle that can be mutually by two chis reads the number of degrees that dial shows, protractor can be used as, so, the present invention can provide a kind of combination drawing tools of Multifunctional convenient type, this combination drawing tools can simplify tedious steps in drawing processes, be convenient for carrying, the combination function of plyability can be realized.
Certainly, combination drawing tools involved in the present invention is not merely defined in structure in the present embodiment.
In addition, in an embodiment, because be provided with the first slide assemblies on the first sliding tray, the first slide assemblies is specially two nut assemblies, secondary chi can be kept to be fixed in the first sliding guide groove slide, so arrange two nut assemblies can put the more stable slip of secondary chi.
In addition, in an embodiment, because the first support and the second support inside cord intersect on the draw point of clutch disk, so can ensure that the first support and described second support inside cord angle are the angle that dial shows.
