Abstract
The invention relates to the field of teaching measuring instruments, particularly to a sucker-type model protractor. The sucker-type model protractor is characterized in that the sucker-type model protractor is mainly composed of a ruler, a protractor unit and a pointer device; an organic glass fiber reinforced plastic is provided with a graduation ruler groove, and a sucker, a model area, an arc-shaped sliding rail, a hanging hole and a turnplate are arranged on the organic glass fiber reinforced plastic in an embedded mode; and a pointer is arranged on the movable turnplate and slides along the arc-shaped sliding rail through a slider to complete the precise angle measurement of the protractor unit. The sucker-type model protractor is simple in structure and easy to manufacture, use and popularize.
Description
Technical field
The present invention relates to a kind of teaching measurer technical field, a kind of model sucker angle square.
Technical background
At present, " the young chi of snake " is the chi that special use comes trace.Set square is the chi of right angled triangle or isosceles triangle, conveniently draws parallel lines or vertical line.Slide ruler: a kind of computational tool.Tape: be commonly used to measure human body parts.Draw chi: be used for measuring building, furniture etc.Slide measure: the more smart little thing of the amount of being used for.In construction with ruler and compasses, instrument natural sciences instructors in teaching that chi is regarded as drawing the straight line of infinite length often has set square, compasses, ruler, Angle protractor etc., and many problems of carrying inconvenience are arranged.In the teaching use, fall on the ground from blackboard through being everlasting careless to slip out of the hand, be easy to hurt and teach teacher and influence teaching time and safety.
Summary of the invention
In order to overcome the vacancy of prior art, the invention provides a kind of model sucker angle square, being convenient for carrying use is the angulation ruler that can inhale on blackboard.
The technical solution adopted for the present invention to solve the technical problems is: described a kind of model sucker angle square, mainly be to be constituted by ruler, angulation and pointer device, be marked with the rule groove, implant sucker 5, model district 7, arc-shaped slide rail 2, hanging hole 8 and rotating disk 9 at perspex steel 1 at perspex steel 1, pointer 3 is installed on the movable disk 9 and finishes the accurate angle of angulation along arc-shaped slide rail 2 with crossing slide block 4.
The invention has the beneficial effects as follows: being convenient for carrying use is that the scale protractor manufactured materials that can inhale on blackboard is originated extensively, and cost is low, and is simple in structure, is convenient to make, and practical, the application market amount is big, and there are great returns of investment the side of practicing midwifery.For remedy some measurer in the use unicity and carry and take care of on the use inconvenience, this product has simple in structure, the modern design uniqueness, reasonable in design, have flexibility and comprehensive practical value in the use, realize multi-use, thereby increased work efficiency, embodied social benefit again.Being convenient for carrying use is the model sucker angle square that can inhale on blackboard.
Therefore the present invention has following advantage: the school of the overwhelming majority is all also using traditional wooden teaching appliance (comprising wooden educational compasses, wooden set square etc.) at present.Though the unit price of this series products is cheap, but damage easily, general school uses an academic year, even halves just needs to change very waste.
Than function: no matter compasses, ellipsograph, set square, protractor, ruler, even the function of teacher's pointer are primary schools, junior middle school, or senior middle school, and buy a cover multifunctional compass and be equivalent to buy 6 teaching aids, it is convenient, powerful to save.
Specific mass: the quality of common wood-based product is needless to say more, and school used all to be known, often falls on the ground because of carelessness just to have dissipated, and is very easy to bad.And adopt superpower plastics to make, falls test through anti-, so long as not wanting intentionally it is broken, at will fall definitely fall not bad.
This model sucker angle square is simple in structure, and is easy to make, popularizes use easily.
Description of drawings
Fig. 1: be structural representation of the present invention
Among the figure: by 1, perspex steel, 2, arc-shaped slide rail, 3, pointer, 4, slide block, 5, sucker, 6, the wave wire casing, 7, the model district, 8, hanging hole, 9, rotating disk.
The specific embodiment
Embodiment: with reference to shown in Figure 1, described a kind of model sucker angle square, mainly be to be constituted by ruler, angulation and pointer device, be marked with the rule groove, implant sucker 5, model district 7, arc-shaped slide rail 2, hanging hole 8 and rotating disk 9 at perspex steel 1 at perspex steel 1, pointer 3 is installed on the movable disk 9 and finishes the accurate angle of angulation along arc-shaped slide rail 2 with crossing slide block 4.This model sucker angle square is simple in structure, and is easy to make, popularizes use easily.
Based on above analysis, the design philosophy of this class is: the student plays an active part in teachers organization, under guiding, coaching, and is diligent in starting, and really in the process of independently probing into cooperation and exchange effectively understands and grasps knowledge.
Above-described embodiment is preferred implementation of the present invention, but embodiments of the present invention are not restricted to the described embodiments, and the present invention not part of detailed description is known technology.
