The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
This practicality can be drawn the multifunctional compass of great circle and straight line, as shown in Figure 1, comprises housing 1, dividing plate 17, compasses pin 16 and tape measure 6.Tape measure 6 and dividing plate 17 are positioned at housing 1 inside, at dividing plate 17 centers, are fixed with winding mechanism.
The end of tape measure 6 is provided with tape measure connector 4, is provided with and pulls auxiliary member 3 on tape measure connector 4.On shell, be also provided with suspension ring hole 10 and be arranged on the suspension ring circle 9 in suspension ring hole 10.
As shown in Figure 2, winding mechanism comprises the cam crank slot A14-1 of mechanism and the cam crank slot B14-2 of mechanism that is separately positioned on dividing plate 17 both sides, and the cam crank slot A14-1 of mechanism and the cam crank slot B14-2 of mechanism link together by central shaft.
On the cam crank slot A14-1 of mechanism, be also provided with cam mechanism mover 19, cam mechanism mover 19 one end are connected with central shaft 20, there is spring 21 central shaft inside, button 2 downwards on time the related cam mechanism mover 19 that presses down play elastic force effect, the other end of cam mechanism mover 19 is provided with button 2, and button 2 exposes in housing 1 outside.The cam crank slot A14-1 of mechanism is cylindrical, is provided with tape measure buckle slot 15 on its sidewall, and its effect is that tape measure 6 one headgears are entered to buckle slot 15, fixedly tape measure.
Around central shaft 20 in the cam crank slot B14-2 of mechanism, be provided with elasticity iron plate bar 25 and elasticity iron plate bar one end is fixed on central shaft 20; The cam crank slot B14-2 of mechanism is cylindrical.
Tape measure 6 is wound on winding mechanism, and tape measure is embedded in dividing plate 17, and tape measure is at its width, the average both sides that are positioned at dividing plate 17.Tape measure 6, is straight-line groove 5 in a side of chi face, and opposite side is fulcrum hole 7, and fulcrum hole 7 is continuously arranged a series of aperture.
Wherein the stiff end of tape measure 6 is connected on the tape measure buckle slot 15 on cam crank slot structure 14.
Tape measure 6 has a side of straight-line groove 5 to be provided with tape measure groove 18, and tape measure 6 is positioned at tape measure groove 18, and the end of tape measure groove 18 is connected with the opening 8 on shell 1,
Housing 1 top is rotary knob part 11, and rotary knob part 11 lower ends are revolving part seat 12, and revolving part seat 12 lower ends are connected with compasses needle control mechanism 13, and compasses needle control mechanism 13 lower ends are connected with compasses pin 16 with spring B 23 by connecting rod 24, control piece 22; The effect of spring B 23 is bounce-back compasses pins 16, and housing 1 makes it to retract.Compasses needle control mechanism 13, control piece 22, connecting rod 24 and compasses pin 16 are positioned at a side of dividing plate, and with tape measure 6 on distribute half of straight-line groove 5 be positioned at same side, control piece 22 and connecting rod 24 are positioned at straight-line groove 5.
Elasticity iron plate bar 25 one end are fixed on central shaft 20, and are wound on around central shaft 20, and the other end is pressed the tape measure buckle slot 15 being fixed on cam crank slot mechanism part 14.
The using method that the utility model can be drawn the multifunctional compass of great circle and straight line is: in needs picture circle, pressing the upper and lower shrinker member 13 of rotary knob key 11 braking compasses pin makes compasses pin 16 pass snail type housing, aim at the center of circle pen is penetrated to required fulcrum hole 7, be pulled outwardly and drive tape measure 6 to pull out, now according to oneself needing the radius cam mechanism mover 19 that stops that the part A14-1 of cam crank slot mechanism is blocked, and radii fixus length, hand is pinched knob 11 another hands and is pinched paintbrush rotation on the other hand, obtains required radius circle.Because snail shell 1 does not limit muchly, not restriction of space, has truly realized the great circle of drawing several meters in shell, simultaneously because being provided with straight-line groove 5, and groove inside-paint straight line very easily after pulling out.Need to regain the tape measure 6 of pulling out painting in round, press the button 2, internal cam mechanism mover no longer blocks cam crank slot mechanism part, and contained spring 21 and elasticity iron plate bar 25 obtain loosening and make tape measure quick rotation and then the fast automatic withdrawal of tape measure 5, presses button 2 and reclaims compasses pin 16.
The utility model can be drawn the multifunctional compass of great circle and straight line, has solved the loosening problems such as inaccuracy drafting is difficult, straight line is not straight that cause drawing of the round size restriction of the compasses picture existing in prior art and stitch.And shrink by pressing the use that compasses pin can be safer.And, can be more convenient to use by stretching tape measure and rotating sliding, not used time tape measure can be effectively in the middle of being automatically contracted in attractive in appearance depositing, after using, only need rotation to regain compasses pin and can avoid unnecessary injury.
