Abstract
The utility model provides a fan with an angle measuring function. The fan comprises two main fan ribs arranged on the outer sides, multiple internal fan ribs and a fan face line, wherein the main fan ribs are hinged to the tail ends of all the internal fan ribs located on the inner sides of the main fan ribs; two ends of the fan face line are respectively and fixedly arranged on the inner side faces of the main fan ribs; the surface of the fan face line is fixedly arranged on the internal fan ribs; the same plane of the front ends of the main fan ribs and the front ends of the internal fan ribs is engraved with scale lines for angle measurement; the extension lines of all the scale lines are intersected at a point where the main fan ribs and the internal fan ribs are hinged; the external surface of one of the main fan ribs is provided with length scale lines for length measurement. The fan has the beneficial effects that the angle measurement and the length measurement are realized; a protractor has flexibility and all-round practical values, and is simple in structure, novel and unique in shape, and rational in design, so that the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of fan that has angle measuring function.
Background technology
In contemporary society, there have been the electrical equipment of avoiding heat such as air condition electric fan, the effect of traditional fan starts to reduce, and fan can only be done decoration collection as handicraft.And the utility model attempts to develop the additional function of fan, allow it continue to become study article common in people's hand.
And protractor is as the necessary study article of Students ' Learning, general semicircular in shape, taking in writing case and Stationery bag seems excessive, unicity in the use and the use inconvenience of carrying and take care of.
Summary of the invention
The utility model for current fan can only be as air inducing instrument, do not there is the problem that study is used, a kind of fan that has angle measuring function that both can be used as the diverse in function of schooling apparatus, easy to carry, fan has been proposed.
A kind of fan that has angle measuring function described in the utility model, comprise and be arranged on two main ribs of the fans in outside, many interior ribs of the fans, covering of the fan line, main ribs of the fan described in two is hinged with all ribs of the fan ends that are positioned at main ribs of the fan inner side, upper end connects by same covering of the fan line between adjacent main ribs of the fan and interior ribs of the fan and between adjacent interior ribs of the fan, it is characterized in that: the front end the same face of described main ribs of the fan and described interior ribs of the fan is carved with the graduation mark for taking measurement of an angle, and the extended line of all graduation marks intersects at the pin joint of main ribs of the fan and interior ribs of the fan; The outer surface of described main ribs of the fan is provided with the length groove for chainage.
Described graduation mark is evenly arranged, and the angle of adjacent two graduation marks representative is identical.
Described covering of the fan line is identical with pin joint distance.
Described length groove is arranged along the long limit of described main ribs of the fan.
Described fan comprises 2 main ribs of the fans and 16 interior ribs of the fans, and the described long 150mm of main ribs of the fan, thick 2mm; The described long 150mm of interior ribs of the fan, thick 1mm.
Described main ribs of the fan adopts PV material to make.
While using as protractor, can with handgrip fan, open the angle identical with angle according to angular dimension, the protractor numerical value according on covering of the fan, draws angular dimension; While using as ruler, fan, in closure state, is alignd the main ribs of the fan of fan with the lines that will measure, by the ruler numerical value on main ribs of the fan, carry out linear measure longimetry, complete linear measure longimetry.
The beneficial effects of the utility model are: measure angle and measure length; Make protractor have flexibility and comprehensive practical value, simple in structure, modern design is unique, reasonable in design, thereby increases work efficiency.
Accompanying drawing explanation
Fig. 1 is deployed condition 3 dimensional drawing of the present utility model.
Fig. 2 is the utility model closure state 3 dimensional drawing.
Fig. 3 is that the utility model covering of the fan connects 3 dimensional drawing.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model
With reference to accompanying drawing:
A kind of fan that has angle measuring function described in the utility model, comprise and be arranged on two main ribs of the fans 1 in outside, many interior ribs of the fans 2, covering of the fan line 3, main ribs of the fan 1 described in two is hinged with all ribs of the fans 2 ends that are positioned at main ribs of the fan 1 inner side, upper end connects by same covering of the fan line 3 between adjacent main ribs of the fan 1 and interior ribs of the fan 2 and between adjacent interior ribs of the fan 2, the front end the same face of described main ribs of the fan 1 and described interior ribs of the fan 2 is carved with the graduation mark 4 for taking measurement of an angle, and the extended line of all graduation marks 4 intersects at the pin joint 5 of main ribs of the fan and interior ribs of the fan; The outer surface of described main ribs of the fan 1 is provided with the length groove 11 for chainage.
Described graduation mark 4 is evenly arranged, and the angle of adjacent two graduation marks, 4 representatives is identical.
Described covering of the fan line 3 is identical with pin joint 5 distances.
Described length groove 11 is arranged along the long limit of described main ribs of the fan 1.
Described fan comprises 2 main ribs of the fans and 16 interior ribs of the fans, and the described long 150mm of main ribs of the fan, thick 2mm; The described long 150mm of interior ribs of the fan, thick 1mm.
Described main ribs of the fan adopts PV material to make.
While using as protractor, can with handgrip fan, open the angle identical with angle according to angular dimension, the protractor numerical value according on covering of the fan, draws angular dimension; While using as ruler, fan, in closure state, is alignd the main ribs of the fan 1 of fan with the lines that will measure, by the ruler numerical value on main ribs of the fan 1, carry out linear measure longimetry, complete linear measure longimetry.
Content described in this description embodiment is only enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also comprises those skilled in the art's equivalent technologies means that design can be expected according to the utility model.
