Description

Novel portable Multifunctional drawing ruler
technical field:
the utility model relates to a kind of novel portable Multifunctional drawing ruler.
background technology:
at present, no matter be at which educational stage, circular arc and the circumference of specific angle, specific size are all indispensable graphic elements, but want that free-hand to finish above-mentioned graphic element be not a nothing the matter, so numerous teachers and students usually need with drawing instruments such as ruler, set square, compasses and protractors to draw accurately and conveniently.For easy to carry, improve teaching efficiency, polytype and size graphic element portable multi-function chi are taken, can be drawn in a defecate collection, seem particularly important.
summary of the invention:
the purpose of this utility model is to provide a kind of novel portable Multifunctional drawing ruler.
above-mentioned object realizes by following technical scheme:
a kind of novel portable Multifunctional drawing ruler, its composition comprises: main scale, secondary chi, described main scale left end has conductor rope base, through hole, described secondary chi left end has screw thread column, pit, described screw thread column is through through hole, on described screw thread column, clockwork spring is installed, described clockwork spring is connected with wiring axle, described wiring axle is connected with fixed knob, below described main scale left end, there is cannelure, positioning convex, in described cannelure, there is one group of spherical groove, above described secondary chi left end, there is locating slot, described main scale, on described secondary chi, there is graduation mark.
described novel portable Multifunctional drawing ruler, described fixed knob is threaded with described screw thread column, described conductor rope base is connected with the knob of admittedly restricting, described solid rope knob is connected with cutting ferrule, in described pit, there is spring, on described spring, have location ball, described positioning convex matches with locating slot, and described location ball is fixed in spherical groove by spring.
described novel portable Multifunctional drawing ruler, described conductor rope base side has wire rope handling through hole, on described wiring axle, has wire rope handling through hole, and described cutting ferrule inside has bellmouth, described cutting ferrule outer end has column, has wire rope handling through hole on described column.
the beneficial effects of the utility model:
1., when the utility model can overcome free-hand graphing, the problem such as size is inaccurate, circular arc is rough, ensures that institute's graphing is accurate, attractive in appearance.
2. the utility model carries conveniently, and there will not be by set square scratch phenomenon.
3. the utility model is multiple functional, not only can draw straight line, vertical line can also be drawn the circular arc of various special angle.
4. the utility model is provided with wire rope handling through hole at conductor rope base and wiring axle, has the effect to rope guiding, makes the position of rope relatively fixing, is convenient to solid chi knob fixing to restricting, and through hole is the initial point to graduation mark just, and it is more accurate to make measurement of length.
brief description of the drawings:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is structural representations of the utility model main scale.
accompanying drawing 3 is structural representations of this practical cutting ferrule.
detailed description of the invention:
embodiment 1:
a kind of novel portable Multifunctional drawing ruler, its composition comprises: main scale 7, secondary chi 9, described main scale left end has conductor rope base 5, through hole 14, described secondary chi left end has screw thread column 13, pit 12, described screw thread column is through through hole, on described screw thread column, clockwork spring 15 is installed, described clockwork spring is connected with wiring axle 16, described wiring axle is connected with solid chi knob 1, below described main scale left end, there is cannelure 17, positioning convex 20, in described cannelure, there is one group of spherical groove 18, above described secondary chi left end, there is locating slot 19, described main scale, on described secondary chi, there is graduation mark 8.
embodiment 2:
according to the novel portable Multifunctional drawing ruler described in embodiment 1, described solid chi knob is threaded with described screw thread column, described conductor rope base is connected with the knob of admittedly restricting, described solid rope knob is connected with cutting ferrule 3, in described pit, there is spring 11, on described spring, have location ball 10, described positioning convex matches with locating slot, and described location ball is fixed in spherical groove by spring.
embodiment 3:
according to the novel portable Multifunctional drawing ruler described in embodiment 1 or 2, described conductor rope base side has wire rope handling through hole 6, on described wiring axle, there is wire rope handling through hole 16, described cutting ferrule inside has bellmouth, described cutting ferrule outer end has column 23, has wire rope handling through hole 22 on described column.
embodiment 4:
according to the novel portable Multifunctional drawing ruler described in embodiment 1 or 2 or 3, first the two ends of clockwork spring are connected with roll with solid chi knob respectively, then pass and fix from the hole of roll with a fine rule, the opposite side of fine rule is connected with cutting ferrule, then spring and solid chi ball are put into successively to the pit of secondary chi, and cover with main scale, finally solid chi knob is spun on to screw thread on the screw thread column that secondary chi leans out.
embodiment 5:
according to the novel portable Multifunctional drawing ruler described in embodiment 1 or 2 or 3 or 4, in the time drawing straight line, length as required only need be outwarded winding main scale, secondary chi and directly be drawn to level or without outwarding winding; Draw when vertical line and major and minor chi can be threaded to 90 °, the spherical groove auto lock of ball on can be along trough roller to respective annular groove.User can be according to the angle that need to draw specific size and the circular arc of oneself.If draw conventional special angle, main scale and secondary chi are rotated to the angle needing to the inner side drafting with pen along main scale and secondary chi according to mark; If draw circular arc, first main scale and secondary chi are threaded to required angle according to mark, the pen (or chalk) of drawing use is inserted to cutting ferrule, unscrew solid rope knob, on main scale, measure required length as arc radius according to size marking, after measuring, revolving fastening rope knob, that cord is fixed in solid rope base is motionless, now, can draw circular arc.
