Abstract
The invention discloses a portable bevel protractor which comprises a first fan frame, a second fan frame and a plurality of fan blades. Each fan blade comprises a fan rib and a fan ruler. One end of each fan rib is fixedly connected with the corresponding fan ruler. A through hole is formed in the other end of each fan rib. The fan ribs are movably connected with the first fan frame through the through holes. The fan rulers are arranged into an arc shape. Angle scales are arranged on the fan rulers. One end of the first fan frame is fixedly connected with one end of the second fan frame. The fan blades are movably connected between the first fan frame and the second fan frame. By means of the mode, the first fan frame, the second fan frame and the fan blades are manufactured according to the manufacturing thought of a feather fan, the angle scales are etched on the fan rulers, the angle of an object is measured through the angle scales on the fan rulers by rotating, folding or opening the fan ribs, measurement is easy, the portable bevel protractor is convenient to carry, the occupied space is small when the portable bevel protractor is stored, the application range is wider, and the use effect is better.
Description
Technical field
The present invention relates to measuring equipment field, particularly relate to a kind of Portable angle chi.
Background technology
Existing bevel protractor takes up room comparatively large, and use comparatively inconvenient, this brings many restrictions to the use of bevel protractor.
Summary of the invention
The technical matters that the present invention mainly solves take up room when being to provide a kind of easy to carry, storage less, usable range is wider, the better Portable angle chi of result of use.
For solving the problems of the technologies described above, the invention provides a kind of Portable angle chi, comprise: the first fan frame, second fan frame and multiple flabellum, described flabellum comprises ribs of the fan and fan chi, one end of described ribs of the fan is fixedly connected with described fan chi, the other end of described ribs of the fan is provided with a through hole, described ribs of the fan is flexibly connected with described first frame by described through hole, circular arc is arranged to by described fan chi, described fan chi is provided with angle index, the end winding support that frame is fanned in described first end and described second of fanning frame is connected, described flabellum is movably connected in described first fan frame and described second and fans between frame.
In a preferred embodiment of the present invention, described flabellum is 3-9.
In a preferred embodiment of the present invention, multiple described flabellum can rotate and fold.
In a preferred embodiment of the present invention, described angle index scope is 0-10 °.
The invention has the beneficial effects as follows: the first fan frame, the second fan frame and multiple flabellum are used for reference the making thinking of feather fan by Portable angle chi of the present invention, angle index is engraved on fan chi, along with the rotation, folding or open of ribs of the fan, the angle of object is measured by the angle index on fan chi, measure simple, easy to carry, take up room during storage less, usable range is wider, and result of use is better.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of Portable angle chi one of the present invention preferred embodiment.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of Portable angle chi, comprise: the first fan frame 1, second fan frame 2 and multiple flabellum, described flabellum comprises ribs of the fan 31 and fan chi 32, one end of described ribs of the fan 31 is fixedly connected with described fan chi 32, the other end of described ribs of the fan 31 is provided with a through hole, described ribs of the fan 31 is flexibly connected with described first frame 1 by described through hole, circular arc is arranged to by described fan chi 32, described fan chi 32 is provided with angle index, the end winding support that frame 2 is fanned in described first end and described second of fanning frame 1 is connected, described flabellum is movably connected in described first fan frame 1 and described second and fans between frame 2.
Described flabellum is 3-9.Flabellum described in the present embodiment is 9.
Multiple described flabellum can rotate and fold.
Described angle index scope is 0-10 °.Angle on flabellum described in the present embodiment is 10 °.
Be different from prior art, first fan frame, the second fan frame and multiple flabellum are used for reference the making thinking of feather fan by Portable angle chi of the present invention, angle index is engraved on fan chi, along with the rotation, folding or open of ribs of the fan, measured the angle of object by the angle index on fan chi, measure simple, easy to carry, take up room during storage less, usable range is wider, and result of use is better.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
