Description
Technical field
The utility model relates to teaching equipment, relates in particular to a kind of multi-functional compasses.
Background technology
The compasses that teaching is used, structure is generally fairly simple, can satisfy teaching demonstration and use; But educational compasses does not generally have gage, can't confirm drawn radius of a circle; During demonstration, because drawn radius of a circle is uncertain, to exerting a certain influence in the teaching explanation.Some educational compasses also has gage, but gage is arranged on the compass leg frame and can't furls, and has caused the volume of educational compasses bigger, and easy-to-collection not.
Use multiple teaching aid in the teaching process, every kind of teaching aid has different functions, and the teacher carries multiple teaching aid through regular meeting and gets into the classroom; Carry very inconvenient; School to the remote districts of one-house show buys multiple teaching aid, and is nervous to the funds of aggravation school; Therefore need develop multi-functional teaching aid, replace the teaching aid of simple function.
Summary of the invention
The utility model technical problem to be solved is: a kind of multi-functional compasses are provided, to realize the function of compasses and religion bar.
For solving the problems of the technologies described above; The technical scheme of the utility model is: multifunctional compass comprises: first supporting leg and second supporting leg, and said first supporting leg and said second supporting leg are hinged; The top of said first supporting leg is provided with the grip part; The said first supporting leg end is provided with the support portion, and the said second supporting leg end is provided with the pen cap, and said first supporting leg is provided with the cell body that is used to hold said second supporting leg near a side of said second supporting leg; Said cell body inside is provided with tape measure near an end of said support portion, and the other end of said tape measure is connected to corresponding position on said second supporting leg; Said support portion is provided with indicator lamp.
As a kind of improvement, said support portion is columniform rotating shaft, and said indicator lamp is arranged on the outer peripheral face of said rotating shaft.
As a kind of improvement, the top of said rotating shaft is provided with the tip of outside protrusion.
Owing to adopted technique scheme; The utility model is provided with the cell body that is used to hold second supporting leg on first supporting leg; Make the dual-use function that the utlity model has compasses and religion bar; The utility model is provided with rotating shaft in the support portion owing to be provided with the support portion, the convenient use of the utility model as compasses; Owing between first supporting leg and second supporting leg, be provided with tape measure, when the utility model uses as compasses, can conveniently measure suitable radius and draw circle; Owing to be provided with indicator lamp in the support portion and be provided with the tip, made things convenient for the use of the utility model as the religion bar at the top, support portion; The utility model is simple in structure, and is convenient and practical, in conjunction with the functions of compasses with the religion bar, helps the spending of saving funds.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Among the figure: 1-first supporting leg; The 11-grip part; The 12-support portion; The 121-tip; The 122-indicator lamp; The 13-cell body; 2-second supporting leg; The 21-pen cap; The 3-tape measure.
The specific embodiment
As shown in Figure 1; Multifunctional compass comprises: first supporting leg 1 and second supporting leg 2, and said first supporting leg 1 is hinged with said second supporting leg 2; The top of said first supporting leg 1 is provided with grip part 11; Said first supporting leg, 1 end is provided with support portion 12, and said second supporting leg, 2 ends are provided with the pen cap 21, and said first supporting leg 1 is provided with the cell body 13 that is used to hold said second supporting leg 2 near a side of said second supporting leg 2; Said cell body 13 inside are provided with tape measure 3 near an end of said support portion 12, and the other end of said tape measure 3 is connected to corresponding position on said second supporting leg 2.Said support portion 12 is provided with indicator lamp 122, and said support portion 12 is columniform rotating shaft, can be laborsaving during use, and said indicator lamp 122 is arranged on the outer peripheral face of said rotating shaft, and the top of said rotating shaft is provided with the tip 121 of outside protrusion.
When the utility model uses as compasses; First supporting leg 1 and second supporting leg were opened in 2 minutes; Confirming radius of a circle according to the tape measure between the two 3, in the pen cap 21 of second supporting leg 2, load onto lettering pen, is that circle is drawn in the center of circle with first supporting leg 1; Because the design of rotating shaft can be saved strength during 2 rotations of second supporting leg.
When the utility model uses as the religion bar, second supporting leg 2 is incorporated in the cell body 13 of first supporting leg 1 into hand-held grip part 11; During use, because rotating shaft has a tip 121, the indication orientation is clear and definite clear; Because indicator lamp 122 has been installed in rotating shaft, 11 places are provided with the switch of said indicator lamp in the grip part, and the teacher says the key content of class hour; Open indicator lamp 122, can deepen student's impression.
Owing to adopted technique scheme; The utility model is provided with the cell body that is used to hold second supporting leg on first supporting leg; Make the dual-use function that the utlity model has compasses and religion bar; The utility model is provided with rotating shaft in the support portion owing to be provided with the support portion, the convenient use of the utility model as compasses; Owing between first supporting leg and second supporting leg, be provided with tape measure, when the utility model uses as compasses, can conveniently measure suitable radius and draw circle; Owing to be provided with indicator lamp in the support portion and be provided with the tip, made things convenient for the use of the utility model as the religion bar at the top, support portion; The utility model is simple in structure, and is convenient and practical, in conjunction with the functions of compasses with the religion bar, helps the spending of saving funds.
