Description
Technical field
The utility model relates to teaching aid technical field, is specially a kind of Novel mathematics teaching teaching aid.
Background technology
More and more perfect along with educational development, teacher is in mathematical education process, frequent use teaching aid is mapped on blackboard, deepen the directly perceived understanding of student to geometric knowledge, especially in geometric construction presentation process, ruler can be used, compasses, protractor teaching aid etc., these teaching aids compare dispersion, need change back and forth during mapping, waste valuable instructional blocks of time, and carry inconvenience, considerably increase the workload of teacher, need often to draw parallel lines in drawing processes, the shapes such as circle, but due to the reason of instrument itself, cause and can not draw desirable use figure, have a strong impact on quality of instruction.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel mathematics teaching teaching aid, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of Novel mathematics teaching teaching aid, comprise shell, protractor, main scale, compasses combined with ruler, chalk clamp, roller, locking pin and slide rail, described main scale is fixedly connected with shell, and main scale inside is provided with protractor, described compasses combined with ruler is interspersed in enclosure, and compasses combined with ruler top is provided with chalk clamp, described roller is located at the bottom of shell, and roller has the interspersed portion in the enclosure of part, and described slide rail is arranged on the inside of shell.
Further, described case surface is provided with scale.
Further, described locking pin is located at the left end side of shell.
Further, described compasses combined with ruler can slide on slide rail, and compasses combined with ruler right-hand member and slide rail coupling part are circular shape.
Compared with prior art, the beneficial effects of the utility model are: by protractor, ruler, compasses, concentrate on an object, carry very convenient like this, compasses combined with ruler can slide on slide rail, length can be regulated as required, and compasses combined with ruler right-hand member and slide rail coupling part are circular shape, avoid and in the process of sliding, occur a card situation at compasses combined with ruler, extend the service life of instrument, locking pin is provided with in case surface, instrument can be fixed up in the process of mapping, avoid choosing in addition trouble and error that scale causes, convenient and practical, outer casing underpart is provided with roller, blackboard can move when not departing from blackboard as required, error can be reduced greatly, facilitate teaching, improve the efficiency of teaching of teacher, reduce working strength.

In figure: 1, shell, 2, protractor, 3, main scale, 4, compasses combined with ruler, 5, chalk clamp, 6, roller, 7, locking pin, 8, slide rail.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-3, the utility model provides a kind of technical scheme: a kind of Novel mathematics teaching teaching aid, comprise shell 1, protractor 2, main scale 3, compasses combined with ruler 4, chalk clamp 5, roller 6, locking pin 7 and slide rail 8, described main scale 3 is fixedly connected with shell 1, and main scale 3 inside is provided with protractor 2, it is inner that described compasses combined with ruler 4 is interspersed in shell 1, and compasses combined with ruler 4 top is provided with chalk clamp 5, described roller 6 is located at the bottom of shell 1, and it is inner that roller 6 has part to intert at shell 1, described slide rail 8 is arranged on the inside of shell 1, compasses combined with ruler 4 can slide on slide rail 8, length can be regulated as required, and be provided with locking pin 7 on shell 1 surface, instrument can be fixed up in the process of mapping, avoid choosing in addition trouble and error that scale causes, convenient and practical, outer casing underpart is provided with roller 6, blackboard can move when not departing from blackboard as required, error can be reduced greatly, described shell 1 surface is provided with scale, scale can be chosen as requested, convenient teaching, described compasses combined with ruler 4 can slide on slide rail 8, and compasses combined with ruler 4 right-hand member and slide rail 8 coupling part are circular shape, avoid and in the process of sliding, occur a card situation at compasses combined with ruler 4, extend the service life of instrument.
Specific works process: when needs picture bowlder, compasses combined with ruler is skidded off, chalk clamp put into by chalk, then locking pin setting tool is used, promote shell, roller starts to rotate, drawn length can carry out choosing required scale according to the scale above shell, when ruler will be needed to measure, compasses combined with ruler is slided in shell, main scale can be used to measure as required, when requirement hornwork, by the figure of main scale near required measurement, readout value is got final product according to protractor, when drawing parallel lines, instrument is made to be close to blackboard, roller is rotated, the different position of main scale is drawn with chalk.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
