Abstract
The utility model relates to stationary, in particular to a multifunctional ruler for mathematics. The multifunctional ruler for the mathematics comprises a fixed ruler body, wherein one end of the fixed ruler body is connected with one end of a left ruler body through a shaft, the other end of the fixed ruler body is connected with one end of a right ruler body through a shaft, moving grooves are formed in the left ruler body and the right ruler body, and the other end of the left ruler body and the other end of the right ruler body are connected through a pin mounted on the moving grooves. A protractor is movably mounted on the fixed ruler body through a rotating shaft. Compared with the prior art, the multifunctional ruler for the mathematics has the advantages of being simple in structure, complete in function, convenient to use and the like.
Description
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 the 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 legofmutton length of side and interior angle all can not arbitrarily be regulated, and have limited the use of set square.Some a kind of multifunctional mathmatical rulers of piecing together occurred now, although function is slightly complete, complex structure, used inconvenience, the teachers ' teaching process has been brought inconvenience, namely lost time and expend teacher's energy.
Chinese utility model patent " a kind of teaching gauge " (patent No.: 2012201458704), a solution is disclosed, its main scale two ends are flexibly connected 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, so that some angles can't directly be drawn, reduced the use value of this chi.
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 a kind of multifunctional mathmatical ruler is provided.
The technical solution of the utility model realizes in the following manner, a kind of multifunctional mathmatical ruler, the fixed ruler two ends connect respectively an end of left chi and right chi by axle, have shifting chute on the blade of left chi and right chi, left chi be connected the other end of chi and connect by the pin that is installed on the shifting chute, be movably installed with protractor by rotating shaft on the fixed ruler.
Further, described pin is alignment pin.
The utility model compared with prior art, have the 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, so that teachers' instruction time mapping is convenient, the content that can intuitively the teacher will be taught is shown to the student, and it is concrete changing abstract, reduce simultaneously teacher's workload, 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.
The specific embodiment
As shown in Figure 1, a kind of multifunctional mathmatical ruler of the utility model, fixed ruler 1 two ends connect respectively an end of left chi 8 and right chi 3 by axle 2, have shifting chute 5 on the blade of left chi 8 and right chi 3, left chi 8 be connected the other end of chi 3 and connect 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, is movably installed with protractor 6 by rotating shaft 7 on the fixed ruler 1.
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 the left chi 8 of conversion 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 affecting angle adjustment, can utilize the 6 pairs of angles of protractor on the fixed ruler 1 to measure simultaneously.
Claims (2)
1. multifunctional mathmatical ruler, it is characterized in that: fixed ruler (1) two ends connect respectively an end of left chi (8) and right chi (3) by axle (2), have shifting chute (5) on the blade of left chi (8) and right chi (3), left chi (8) be connected the other end of chi (3) and connect by the pin (4) that is installed on the shifting chute (5), fixed ruler (1) is upper to be movably installed with protractor (6) by rotating shaft (7).
