Abstract
The utility model discloses a multifunctional angle ruler, which comprises a main ruler 1. The main ruler is movably connected with a base-ruler 2. The utility model is characterized in that the base-ruler 2 is movably connected with an auxiliary ruler 3. The utility model has simple structure, can be conveniently used, is widely applied and can be used for directly reading the measured angle quantitatively.
Description
(1) technical field: the utility model relates to a kind of chi, relates in particular to a kind of multifunctional angular chi.
(2) background technology: the problem that takes measurement of an angle that in industrial and agricultural production, is run at present, using maximum is the two ends formula chi (referring to Fig. 3) of living, it is made up of a basic chi and a main scale, its operation principle is to be the axle center through the A point, comes angle is surveyed and drawn and processed by the angle that changes main scale and basic chi, and the angle of Ce Lianging can not quantize like this, not readable, can't narrate out the size of its angle in theory, and very inconvenient in actual applications, and range of application is narrow.
(3) the purpose of this utility model is to improve the deficiency of above-mentioned prior art and provides a kind of simple in structure, easy to use, is widely used, and can directly quantize to read the multifunctional angular chi of institute's angle measurement degree.
The purpose of this utility model can reach by following measure: a kind of multifunctional angular chi, and it comprises main scale 1, main scale 1 flexibly connects basic chi 2, it is characterized in that described basic chi 2 flexibly connects an auxilliary chi 3.
In order further to realize the purpose of this utility model, between described main scale 1 and the basic chi 2, be spool to be connected between basic chi 2 and the auxilliary chi 3.
In order further to realize the purpose of this utility model, described main scale 1 is provided with on length scale, angle index base chi 2 and the auxilliary chi 3 and is respectively equipped with the length scale, and basic chi 2 is provided with the low-angle scale.
In order further to realize the purpose of this utility model, described basic chi 2 is provided with horizontal glass ball 7.
In order further to realize the purpose of this utility model, described main scale 1 is provided with chute 4, is inserted with feather key 5 in the chute 4, and feather key 5 links to each other with auxilliary chi 3.
Slide mouth 6 in order to realize that further the purpose of this utility model, described auxilliary chi 3 are provided with.
In order further to realize the purpose of this utility model, the length of described auxilliary chi 3 is more than or equal to 2 times of the length of basic chi 2, and the length sum of basic chi 2 and auxilliary chi 3 is smaller or equal to the length of main scale 1.
The utility model can produce following good effect compared with the prior art: the utility model is simple in structure, easy to use, not only can directly quantize to read institute's angle measurement degree, and be widely used, but its ruler, bevel protractor, rail use, also can measure azimuth, the angle of gradient and perpendicularity.
(4) description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged axonometric map that the C of Fig. 2 is ordered;
Fig. 3 is the structural representation of existing two ends formula chi alive.
(5) below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated:
Embodiment: a kind of multifunctional angular chi is (referring to Fig. 1-Fig. 2), it comprises main scale 1, main scale 1 flexibly connects basic chi 2 by axle, base chi 2 flexibly connects an auxilliary chi 3 by axle, main scale 1 is provided with the length scale, angle index, base chi 2 is provided with the length scale, the low-angle scale, auxilliary chi 3 is provided with the length scale, main scale 1 is provided with chute 4, the other end of auxilliary chi 3 is connected with feather key 5 by bolt, feather key 5 inserts in the chute 4, and basic chi 2 is provided with horizontal glass ball 7, and auxilliary chi 3 is provided with and slides mouth 6, the length BC of auxilliary chi 3 is more than or equal to 2 times of the length A B of basic chi 2, and the length sum AB+BC of basic chi 2 and auxilliary chi 3 is smaller or equal to the length A D of main scale 1.
