Abstract
The utility model relates to a multi-functional mapping instrument, belonging to a drawing tool; the utility model comprises a base board, a rotary ruler and bow shape or incomplete ring shape vacancy arranged on the base board, and is characterized in that the rotary ruler and the base board are penetrated and collected together by a pin shaft arranged at the centre of circle of the vacancy circle arc. The mapping instrument collects a set square, a straight ruler and a protractor to integration, and the angle of fixed value, the table, the vector mapping, etc. can be drawn conveniently; the utility model can be used as a drawing tool for students and engineers and technicians, and can also be used as a teaching aid for teachers as well as a scribing tool for plate work workers. The utility model has the advantages of easy fabrication, easy fabrication and low cost.
Description
The utility model relates to drawing instrument.
In order to draw the convenience of figure, table, the drawing appliance that integrates multiple drawing instruments such as set square, protractor, ruler occurs in succession, but disclosed example at present just exists the situation of attending to one thing and lose sight of another.Though solved the problems of using as CN88210715U, the structure of this surveying instrument is comparatively complicated more, and processing is inconvenient, and cost is also corresponding to be increased.The CN88219499 structure is comparatively simple, and still not too convenient on using, and during as picture certain value angle, needs fixed point earlier, draws straight line again, and is cumbersome.
It is one that the purpose of this utility model is to provide drawing instruments such as collection set square, ruler, protractor, the definite value angle of directly drawing, thereby multifunctional drawing utensil that bring convenience to the user and simple in structure.
The utility model includes a base plate and changes chi, the global shape of base plate can be a triangle, semicircle, squares etc. are geometric figure arbitrarily, can indicate the length scale on its straight line, base plate is provided with incomplete annular or arc vacancy, the entity of its circular arc periphery is marked with angle index, it is characterized in that described commentaries on classics chi and base plate are worn by bearing pin connects together, the center of circle of vacancy circular arc overlaps on the axis of this bearing pin and the base plate, thereby make rotating the needle do rotating around bearing pin relative to base plate, become an activity point of view chi, the size that both can take measurement of an angle also can be according to angle value, the sideline at the required angle of drawing easily, angular bisector etc.
For the commentaries on classics chi can be attached on the base plate preferably; can on the entity of described base plate vacancy circular arc periphery, the concentric arc guide rail be set, establish slide block on the commentaries on classics chi relevant position and be mated, can reduce the commentaries on classics chi like this and rock; use more conveniently, and protection is changeed chi and is not damaged.
Be further described below in conjunction with embodiment:
The connected mode that structural representation when Fig. 1 is the base plate semicircular in shape, its A-A figure have been explained base plate 1 and changeed chi 2,4 is rivet, changeing ruler end part has square protruding 5 as slide block, is engaged in the groove 3 of base plate.6 is fastening bolt, and it can make the fixed-site of changeing chi get off when needed.
Fig. 2 is the another embodiment outline drawing.
The utility model can be used as student and engineers and technicians' drawing instrument, play the effect of set square, ruler and protractor simultaneously, the definite value angle of can drawing easily, angular bisector, regular polygon, make form etc., because it can express angle and length dimension accurately and easily, calculate simultaneously thereby help carrying out vector greatly with graphing method.
The utility model can be made the series of products of different size, different base plate shapes according to user's needs, can be used as sheet metal workman's scoring tool, also can be used as teacher's teaching aid.
The utlity model has following advantage:
1. realized the many usefulness of a chi, easy to use, can satisfy the multiple demand of common drawing.
2. simple in structure, easy to make, with low cost.
Claims (2)
1, a kind of multi-functional surveying instrument, include a base plate 1 and change chi 2, arc or incomplete annular vacancy is arranged on the base plate 1, entity at vacancy circular arc periphery is marked with angle index, it is characterized in that described commentaries on classics chi 2 and base plate 1 are worn by bearing pin 4 connects together, and the center of circle of vacancy circular arc overlaps on this bearing pin axis and the base plate.
2, surveying instrument according to claim 1 is characterized in that on the entity of described base plate vacancy circular arc periphery concentric arc guide rail 3 being set, and it and the slide block 5 that changes on the chi relevant position match.
