Abstract
According to the International Patent Classification (IPC), a set square for teaching belongs to the technical field of the group of rulers, the subclass of writing or plotting supplies and writing or plotting accessories, the large class of writing or plotting apparatuses and office supplies, the branch of printing, the category of operation and transportation. The set square for teaching aims to solve the problems of fixation, bendability and slip resistance, and comprises a set square, graduations, a fixed handle and antiskid film. The set square for teaching is characterized in that the whole set square is formed through rubber processing, the two ends of the fixed handle is fixedly mounted in the middle of the set square, and the outer surface of the fixed handle is coated by the whole antiskid film.
Description
(1) technical field:
The utility model relates to the teaching set square, divides by International Patent Classification (IPC) (IPC) to belong to operation Department of Transportation, and printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; The assistant product group of writing or draw, the ruler technical group field.
(2) background technology:
At present, the technology about the ruler group existing and that once had was all done very fruitful effort to teaching with the needs of set square, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 2008 by Wang Qi, Granted publication number is CN 2696857Y, China Patent No. (ZL) is: 200820031219.X number utility model title is the utility model patent of " concentric circles plotter ", the technical scheme that is adopted, ruler group technical elements be an example very in the invention that is worth, this has solved the concentrically ringed technical problem of plotter effectively.But still have some deficits, it also is difficult to solve fixing, flexible; Anti-skidding technical problem.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of teaching set square.Fixing to solve, flexible; Anti-skidding technical problem.
The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: set square is used in the utility model teaching, mainly is made of set square, scale, fixed handle, non-skid film.Its major part non-skid film is selected for use by market.Its set square is triangular shaped, is material with rubber, through the machined manufacturing.Its fixed handle is a cylindrical shape, is material with the duroplasts, through the machined manufacturing.
In shape, structure and combination thereof, teaching of the present utility model with the essential features that set square and immediate prior art have is: the integral body of set square is by injection moulding process machine-shaping, and process corresponding scale in its side, be combined into triangular shaped integrative-structure, function has been the effect of measuring.In shape, structure and combination thereof, teaching of the present utility model with the set square technical characterictic different with immediate prior art is: the integral body of set square forms with rubber processing, the center fixed of set square installs and fixes the two ends of handle, be combined into triangular shaped integrative-structure, function has been fixing, flexible effect.The integral body of non-skid film is coated in the outer surface of fixed handle, is combined into erose combining structure, and function has been anti-skidding effect.So just reached teaching of the present utility model the fixing, flexible of set square; Anti-skidding purpose.
The teaching of utility model is that the utility model is that solution is fixing, flexible with the beneficial effect of set square; The anti-skidding technical scheme that technical problem adopted has been compared two place's advantage and improvement with existing with the technology about the ruler group that once had:
The first, form with rubber processing owing to designed the integral body of set square in the technical scheme of teaching of the present utility model with set square, the center fixed of set square installs and fixes the two ends of handle, so easier solution is fixed, flexible technical problem.
The second, owing to designed the outer surface that the integral body of non-skid film is coated in fixed handle in the technical scheme of teaching of the present utility model with set square, so the anti-skidding technical problem of easier solution.
(4) description of drawings:
Accompanying drawing provides the structural representation of the utility model teaching with set square:
Fig. 1: be the overall structure schematic diagram of the utility model teaching with set square.
The label declaration at each position in the schematic diagram;
1 set square, 2 scales, 3 fixed handles, 4 non-skid films
(5) specific embodiment:
Below in conjunction with accompanying drawing, be to realize that solution is fixing, flexible to teaching set square of the present utility model; The optimal way of the technical scheme that anti-skidding technical problem is taked is described further:
Its static structure: see also accompanying drawing: as shown in the figure, teaching set square of the present utility model mainly is made of set square 1, scale 2, fixed handle 3, non-skid film 4.Its major part non-skid film 4 is selected for use by market.Its set square 1 is triangular shaped, is material with rubber, through the machined manufacturing.Its fixed handle 3 is cylindrical shapes, is material with the duroplasts, through the machined manufacturing.
In shape, structure and combination thereof, teaching of the present utility model with the essential features that set square and immediate prior art have is: the integral body of set square 1 is by injection moulding process machine-shaping, and process corresponding scale in its side, be combined into triangular shaped integrative-structure, function has been the effect of measuring.In shape, structure and combination thereof, teaching of the present utility model with the set square technical characterictic different with immediate prior art is: the integral body of set square 1 forms with rubber processing, the center fixed of set square 1 installs and fixes the two ends of handle 3, be combined into triangular shaped integrative-structure, function has been fixing, flexible effect.The integral body of non-skid film 4 is coated in the outer surface of fixed handle 3, is combined into erose combining structure, and function has been anti-skidding effect.
Below by using method, further set forth the dynamic structure relation of the utility model teaching: in use with set square, when needs fix, flexible the time, according to theory of mechanics, at first the integral body of set square 1 forms with rubber processing, the center fixed of set square 1 installs and fixes the two ends of handle 3, thereby finishes fixing, flexible task.
In use, when needs were anti-skidding, according to theory of mechanics, at first the integral body of non-skid film 4 was coated in the outer surface of fixed handle 3, thereby finished anti-skidding task.So just realized the utility model teaching the fixing, flexible of set square; Anti-skidding technical problem.
Realize that the utility model preferred plan is with plastics, elastomeric material, utilize the basic equipment of common process factory, take to produce by batch in a large number,, so just can realize practical value and the economic worth of the utility model teaching better with set square with the demand of supply educational circles.
