The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is elaborated.
The utility model provides a kind of combined sucker formula drawing ruler and gauge, as shown in Figure 1, comprise Acetabula device 1, Acetabula device 1 is connected with folding rule 2, as shown in Figure 2, the upper surface of folding rule 2 is rotatably connected to ruler 4 by rotating shaft 7, and folding rule 2 is common through chalk clamping device 3 with ruler 4, the top of folding rule 2 is provided with the first magnetic strips 5, and the top of ruler 4 is provided with the second magnetic strips 6.
As shown in Figure 3, Acetabula device 1 comprises the sucker 101 of quality of rubber materials, the upper end of sucker 101 is connected with connecting rod 102, the top of connecting rod 102 is rotatably connected to cam 104, the outside of connecting rod 102 and between cam 104 and sucker 101, is sheathed with one end of the first cutting ferrule 103, the first spring 102 and folding rule 2 from top to bottom successively; As shown in Figure 4, the inside of sucker 101 is respectively arranged with the second spring 106 and magnet 107.
As shown in Figure 5, chalk clamping device 3 comprises that one end of the second cutting ferrule 301, the second cutting ferrules 301 is provided with circular hole 302, and chalk sleeve 303 is inserted in circular hole 302, chalk sleeve 303 along it, be axially provided with chalk jack 305; The rear end of the second cutting ferrule 301 is respectively arranged with first hole 306 and second hole 307 from top to bottom, after folding rule 2 and ruler 4 are superimposed, from second hole 307, passes.
The front end arranged outside of the second cutting ferrule 301 has the first trip bolt 304, the first trip bolts 304 for chalk sleeve 303 is clamped in to circular hole 302.
The rear end arranged outside of the second cutting ferrule 301 has the second trip bolt 308, the second trip bolts 308 for folding rule 2 and ruler 4 are clamped in to second hole 307.
During use, first with Acetabula device 1, hold blackboard, concrete steps are, cam 104 is rotated as level from vertical state, when cam 104 rotates, successively to pressing down the first cutting ferrule 103, the first spring 102, folding rule 2, until press to sucker 101, by the Bas Discharged between sucker 101 and blackboard, sucker 101 just can suck on blackboard surface; Wherein the effect of the second spring 106 is to make that the bottom of sucker 101 is stressed is conducive to the discharge completely of air with evenly, increases the suction between sucker 101 and blackboard; The effect of magnet 107 is also in order further to increase the suction of sucker 101; Then in chalk jack 305, insert chalk, then use the first trip bolt 304 by chalk sleeve 303 fixations; Regulate again the folding rule 2 and the ruler 4 that mutually stack to determine the size that will draw, finally with chalk, draw.
For example, while drawing circle or circular arc, take sucker 101 as the center of circle, by regulating the position of chalk clamping device 3 on folding rule 2, select corresponding scale value as radius, then, by rotating folding rule 2 around connecting rod 102, make chalk on blackboard, draw the track of a circular arc.
While drawing angle, remove chalk clamping device, and one rotating shaft 7 be axle, rotate ruler 4 so that vertical between ruler 4 and folding rule 2, recycle the first magnetic strips 5 and the second magnetic strips 6 is adsorbed in folding rule 2 and ruler 4 on blackboard respectively, the angle of then drawing as required, regulate the angle between ruler 4 and folding rule 2, the graduation mark being evenly carved with corresponding to angle for one week around rotating shaft on folding rule 2, user relies on angle index line between ruler 4 and folding rule 2, to be adjusted to the angle needing, and then along ruler 4 and folding rule 2, rule respectively with chalk, can draw the angle needing.
By the way, combined sucker formula drawing ruler and gauge of the present utility model adopts sucker that the center of circle is fixed, and has solved to paint the bowlder center of circle and easily depart from the inaccurate problem of drawing; This combined type drawing ruler and gauge adopts the first trip bolt and the second trip bolt, can clamp easily chalk sleeve, and dismounting easily, chalk sleeve can be used separately, and be adsorbed on blackboard; Magnetic stripe is all installed on folding rule and ruler, and the position while making to draw is more accurate, and this combined sucker formula drawing ruler and gauge is simple in structure, easy to use, is suitable for promoting the use of at teaching field.
