Abstract

The utility model relates to stationery, in particular to a multifunctional mathematical ruler. The multifunctional mathematical ruler is formed in a manner that one end of a left ruler and one end of a right ruler are connected to the two ends of a fixed ruler respectively through shafts, moving grooves are formed in the body of the left ruler and the body of the right ruler, and the other end of the left ruler and the other end of the right ruler are connected through a pin arranged on the moving grooves; an angle gauge is movably arranged on the fixed ruler through a rotating shaft; a rotating handle is movably arranged on one of the shafts, scales are arranged on the body of the rotating handle, and a chalk hole is formed in the outer end of the rotating handle. Compared with the prior art, the multifunctional mathematical ruler has the advantages of being simple in structure, complete in function, convenient to use and the like.

Description

Multifunctional mathmatical ruler
Technical field
The utility model relates to a kind of stationery, specifically a kind of teaching gauge of mathematics teacher's special use.
Background technology
Math teacher is given lessons and often will be used educational aids such as fixed ruler, set square, protractor on mathematics class, and the set square of prior art substantially all is drawing square or the isoceles triangle chi of fixing, its leg-of-mutton length of side and interior angle all can not regulated at will, limited the use of set square.Occurred some multifunctional mathmatical rulers of piecing together now, though function is complete slightly, complex structure, used inconvenience, the teachers ' teaching process has been brought inconvenience, namely lost time and expend teacher's energy.
China's utility model patent " a kind of teaching gauge " (patent No.: 2012201458704), a solution is disclosed, its main scale two ends flexibly connect two adjustable rules by bearing pin respectively, all be provided with chute on two adjustable rules, connect by the set bolt that is installed on the chute between two adjustable rules.This scheme has solved the problems referred to above to a certain extent, but in practice is used, find because the protractor of this chi is fixed structure, its position influence the angular transformation scope of adjustable rule, make some angles directly to draw, reduced the use value of this chi; The main scale of this chi and adjustable rule can't be drawn the angle greater than 90 less than 90 degree; Owing to do not have special handle in this scheme, cause the meeting when drawing of this chi unstable because fixing, and influence drawing quality.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, multiple functional multifunctional mathmatical ruler is provided.
The technical solution of the utility model realizes in the following manner, multifunctional mathmatical ruler, the fixed ruler two ends connect an end of left chi and right chi respectively by axle, have shifting chute on the blade of left chi and right chi, and the other end of left chi and right chi is connected by the pin that is installed on the shifting chute; Be movably installed with protractor by rotating shaft on the fixed ruler; Be movably installed with a rotating handle on the described axle, the handle of rotating handle is provided with scale on one's body, and termination, rotating handle outer end is provided with the chalk hole.
As the further optimization of scheme, the two-sided scale that is provided with of the handle body of described rotating handle.
The utility model compared with prior art, have characteristics such as simple in structure, multiple functional, easy to use, integrate multiple educational aid, can be used as curve ruler, fixed ruler, protractor and set square and use, and two edge lengths of set square are adjustable, the direction of protractor can be transferred, it is convenient to map when making teachers' instruction, and the content that can intuitively the teacher will be taught is shown to the student, and it is concrete changing abstract, reduce teacher's workload simultaneously, time saving and energy saving.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, fixed ruler 1, axle 2, right chi 3, pin 4, shifting chute 5, protractor 6, rotating shaft 7, left chi 8, rotating handle 9, chalk hole 10, scale 11.
The specific embodiment
As shown in Figure 1, multifunctional mathmatical ruler, fixed ruler 1 two ends connect an end of left chi 8 and right chi 3 respectively by axle 2, have shifting chute 5 on the blade of left chi 8 and right chi 3, and the other end of left chi 8 and right chi 3 is connected by the pin 4 that is installed on the shifting chute 5; Be movably installed with protractor 6 by rotating shaft 7 on the fixed ruler 1; Be movably installed with a rotating handle 9 on the described axle 2, the two-sided scale 11 that is provided with of the handle body of rotating handle 9, termination, rotating handle 9 outer end is provided with chalk hole 10.
The utility model multifunctional mathmatical ruler, fixed ruler 1 two ends connect an end of left chi 8 and right chi 3 respectively by axle 2, have shifting chute 5 on the blade of left side chi 8 and right chi 3, the other end of left side chi 8 and right chi 3 is connected by the pin 4 that is installed on the shifting chute 5, described pin 4 is alignment pin, can fix the position of left chi 8 and right chi 3 after adjust the position; Be movably installed with protractor 6 by rotating shaft 7 on the fixed ruler 1; Be movably installed with a rotating handle 9 on the described axle 2, termination, rotating handle 9 outer end is provided with chalk hole 10.
During use, can unscrew pin 4, adjust the position of its shifting chute 5 on left chi 8 and right chi 3, thereby the angle between conversion left side chi 8 and right chi 3 and the fixed ruler 1, during aforesaid operations, protractor 6 can be forwarded to the below with fixed ruler 1, avoid influencing angle adjustment, can utilize the 6 pairs of angles of protractor on the fixed ruler 1 to measure simultaneously.Rotating handle 9 can rotate arbitrarily, is used for drawing the angle greater than 90 degree, and can directly draw camber line by the chalk hole 10 on the rotating handle 9, and the handle of rotating handle 9 scale 11 on one's body can read radius size, more is conducive to draw.
