Abstract
The utility model relates to a multi-purpose zigzag rule, which comprises a plurality of holed graduation scales, a mini-type protractor, screws, and rivets (with centering pins). The utility model is characterized in that: two holed graduation scales (master/slave scales) and the mini-type protractor are fixed by the rivets (containing centering pins). The utility model can be used for drawing geometric figures in place of compass, set square, and ruler.
Description
Technical field
The utility model relates to the more teaching aid of a kind of function, the trisquare of using particularly easy to use and carry more
Background technology
Till now, the teaching aid of teachers and students' usefulness all is: ruler (scale), set square (two), compasses, protractor [scaling chi and dip meter (rarely found)].Because kind is many, volume is big, runs into the figure that has and need use a few teaching aid simultaneously, and teacher (student) always will be with a lot of, and is very inconvenient.
Summary of the invention
Existing teaching aid sample number is many, volume is big in order to solve, and carries, awkward problem, and the utility model provides a kind of trisquare, and this trisquare not only function is many, and volume is little, and is simple in structure, flexible and convenient to use
The technical scheme that its technical problem that solves the utility model adopts is:
Miniature protractor and main scale are fixed (miniature protractor also can be engraved on the main scale) with rivet (containing centering pin), and secondary chi is connected with main scale.Secondary chi can rotate arbitrarily angled around rivet (containing centering pin).Major and minor chi is equivalent to the rule of a block length has been shunk half, the aperture on the rule not only as fixing paintbrush with but also fixed screw holes during as the standby chi of interpolation.0 degree line of protractor overlaps with the directrix of main scale.The figure that relates to the angle in the teaching almost can both be drawn.Add two standby chis, can form scaling chi described point trace.
The beneficial effects of the utility model are:
The common ground of multiple teaching aid is mainly concentrated on two porose rules, make its simple structure, volume reduces, operation and easy to carry.
Description of drawings
In conjunction with the accompanying drawings and embodiments to the utility model explanation.
Fig. 1 is main models figure of the present utility model
Fig. 2 is standby chi illustraton of model
Fig. 3 is standby fixed screw (button) illustraton of model
Among Fig. 1,1. 4. 5. 6. aperture of main scale of directrix of the 3. secondary chi of the 2. miniature protractor of rivet (containing centering pin)
Among Fig. 2,1. standby chi (polylith can be arranged)
Among Fig. 3,1. fixed screw (button), 2. nut
The specific embodiment
In Fig. 1, rivet (containing centering pin) 1., miniature protractor 2. with main scale 5., secondary chi is 3. fixing, and can be around rivet (containing centering pin) rotation, the pen of mapping usefulness is inserted corresponding aperture as required, just can draw.
In Fig. 2,1. be several standby chis, their shape, size are congruent fully, scale, pitch-row and main scale also in full accord.They with the 3. secondary chi of main scale 5. can with screw 1. nut 2. (buckle) and be connected.
In Fig. 3, be used for the screw that 5. is connected with the 3. secondary chi of main scale 1. nut 2. (buckle).
Claims (1)
1. using trisquare one kind more, form, it is characterized in that: two porose rules and miniature protractor are fixed with rivet by several porose rules, miniature protractor, screw, a rivet.
