The utility model has the beneficial effects that easy to use, design is reasonable:
1) graduated scale and protractor are set on box cover simultaneously, achieve the purpose that a ruler is multi-purpose, avoid teacher from carrying a variety of
Teaching gauge is attended class, time saving and energy saving；
2) it is spliced into plectane using two protractors, plays the purpose of 360 degree of measurement angles, no longer need to rotation angulation
Device, it is easy to use；
3) dial plate and arm for direction indicator are used, achieved the purpose that measurement direction and is drawn according to known direction；
4) design for using box cover and box body plays the role of separated measurement and is used separately.
This combined appliance for teaching kit function is strong, has achieved the purpose that a teaching-aid box multiple use.
Detailed description of the invention:
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model box cover structural schematic diagram；
Fig. 3 is the utility model box body structural schematic diagram.
Specific embodiment:
Referring to each figure, the utility model specifically uses and mode is implemented as follows: including box body 1 and box cover 2, box body 1 and box cover 2
It is made of transparency glass plate or plastic plate, 1 top of box body is equipped with box cover 2, is equipped with the first magnetic patch in 1 surrounding edge of box body
10, the second magnetic patch 3 is equipped on 2 bottom end edge of box cover, the second magnetic patch 3 and the first magnetic patch 10 cooperate, the box
Round dial plate 8 is inlaid on 1 bottom plate of body, described 2 top surface a side of box cover is inlaid with below graduated scale 5 along graduated scale 5 is equipped with
First protractor 6 and the second protractor 9, the first protractor 6 and the second protractor 9 are in semicircle shape, the first protractor 6 and second
Protractor 9 is spliced to form a plectane and is centrally formed a circular hole 7, impartial on 7 outer circumference surface of circular hole centered on circular hole 7
Equipped with arm for direction indicator 4,4 numbers of arm for direction indicator are eight；7 center of circular hole and round dial plate 8 are located on same axis；Institute
2 upper surface of box cover stated is equipped with handle 11.The respectively northern pointer of the arm for direction indicator 4, northeast pointer, eastern pointer, the southeast refer to
Needle, southern pointer, southwestern pointer, western pointer and northwest pointer.Northwest pointer, northern pointer and northeast in the arm for direction indicator 4
Pointer respectively corresponds 45 °, 90 ° and 135 ° in the first protractor 6；Southwestern pointer, southern pointer and southeast pointer respectively correspond the
45 °, 90 ° and 135 ° in two protractors 9；Western pointer and eastern pointer respectively correspond the first protractor 6 and the overlapping of the second protractor 9
0 ° and 180 °.Diameter of the diameter of the round dial plate 8 less than the first protractor 6 and the second protractor 9 splicing plectane.
It is attracted by the first magnetic patch 10 and the second magnetic patch 3 when this teaching-aid box is not used, so that box cover 2 is fixed on box body 1
On, this teaching-aid box uses, and by handle 11, box cover 2 is removed from box body 1, and the graduated scale 5 that box cover 2 is equipped with is horizontal straight
