Abstract
The utility model relates to the technical field of mathematics teaching tools, in particular relates to a movable mathematics teaching board. The movable mathematics teaching board comprises a guiding frame and teaching boards, wherein the teaching boards are arranged in the guiding frame, and comprise a front teaching board and a back teaching board; a front slideway and a back slideway are respectively arranged at the left side and the right side of the guiding frame; the front teaching board is arranged in the front slideway; the back teaching board is arranged in the back slideway; the front teaching board and the back teaching board are connected with each other by a chain and a chain wheel; the chain wheel is fixed on the top of the guiding frame; a circle of sliding chutes are respectively formed on the edges of the front teaching board and the back teaching board; rolling balls are arranged in the sliding chutes; and a straight ruler is connected to the rolling balls. Compared with the prior art, the movable mathematics teaching board has the advantage of novel and simple structure; and moreover, the writing space of the teaching board surface is fully utilized, the influence of powder dust to the bodies of teachers is reduced, and the movable mathematics teaching board is convenient to draw and flexible to operate, and therefore, the movable mathematics teaching board is a very ideal teaching tool at schools.
Description
[technical field]
The utility model relates to mathematical education apparatus technical field, specifically a kind of portable mathematical education plate.
[background technology]
At present, the teaching plate that school generally uses is one of integral body, and its plate face is fixed; Saying class hour, the teacher that height is not too high often can't use top plate face, thereby its scope of writing is limited to very much; Can only wipe the front content written so that then down write when writing when full; Take notes and do not catch up with regard to there being some to write slow classmate like this, and the teacher often erases the board and can suck amounts of dust, influence healthy; And, in the mathematical education process, often need mapping explanation demonstration on the teaching plate, as draw parallel lines and the teaching figure of reference axis and so on; Existing way is that the teacher holds ruler on the other hand high, a hand-held chalk mapping, and operation is trouble very; Waste time and energy, increased work difficulty, and always draw nonstandard; Bring inconvenience to the teacher, influenced efficiency of teaching and teaching process, can increase teacher's working strength simultaneously to a certain extent.
[utility model content]
The purpose of the utility model is exactly will solve above-mentioned deficiency and a kind of portable mathematical education plate simple in structure, easy to use is provided; Not only made full use of the space of writing of teaching plate plate face; Reduced the influence of dust, and it is easy to map, flexible operation to teacher's health.
For realizing that above-mentioned purpose designs a kind of portable mathematical education plate, comprise leading truck 1 and teaching plate, said teaching plate is installed in the leading truck 1; Teaching plate 2 and back teaching plate 3 before said teaching plate comprises, slideway 4 and rear slide 5 before said leading truck 1 left and right sides is respectively equipped with, teaching plate 2 before being equipped with in the said preceding slideway 4; Teaching plate 3 in back is housed in the said rear slide 5; Teaching plate 2 links to each other through chain 6, sprocket wheel 7 with back teaching plate 3 before said, and said sprocket wheel 7 is fixed on leading truck 1 top, and the edge of said preceding teaching plate 2, back teaching plate 3 is respectively equipped with a circle chute 8; Be provided with ball 9 in the said chute 8, be connected with ruler 10 on the said ball 9.
The minor face of teaching plate 2 or back teaching plate 3 before the length of said ruler 10 is no more than.
The utility model is compared with prior art; Novel structure, simple and since be provided with moving up and down before teaching plate and back teaching plate, and impart knowledge to students size, the weight of plate of preceding teaching plate and back is identical; Gently lift and arbitrarily to move with have gentle hands; Thereby be applicable to the teacher of various heights, made full use of the space of writing of teaching plate plate face, reduced the influence of dust teacher's health; And can be along the plate ruler of rotation all around of imparting knowledge to students owing on preceding teaching plate and back teaching plate, being respectively equipped with; The parallel lines that mathematics is used thereby the utility model can be used for drawing or reference axis etc., its mapping is easy, flexible operation; Very easy to use, be that school uses very desirable teaching aid.
[description of drawings]
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side structure sketch map of the utility model;
Among the figure: 1, leading truck 2, preceding teaching plate 3, back teaching plate 4, preceding slideway 5, rear slide 6, chain 7, sprocket wheel 8, chute 9, ball 10, ruler 11, scale.
[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
With shown in the accompanying drawing 2, the utility model comprises like accompanying drawing 1: leading truck 1 and teaching plate, and said teaching plate is installed in the leading truck 1; Teaching plate 2 and back teaching plate 3 before said teaching plate comprises; The plate 2 of imparting knowledge to students before said is identical with size, the weight of back teaching plate 3, slideway 4 and rear slide 5 before said leading truck 1 left and right sides is respectively equipped with, teaching plate 2 before being equipped with in the said preceding slideway 4; Teaching plate 3 in back is housed in the said rear slide 5; Teaching plate 2 links to each other through chain 6, sprocket wheel 7 with back teaching plate 3 before said, and said sprocket wheel 7 is fixed on leading truck 1 top, and the edge of said preceding teaching plate 2, back teaching plate 3 is respectively equipped with a circle chute 8; Be provided with ball 9 in the said chute 8; Be connected with ruler 10 on the said ball 9, the minor face of teaching plate 2 or back teaching plate 3 before the length of said ruler 10 is no more than, the tip edges of said preceding teaching plate 2 and back teaching plate 3 is respectively arranged with scale 11.
In the utility model, preceding teaching plate has been realized moving up and down through chain, sprocket wheel with back teaching plate, and promptly preceding teaching plate can freely move up and down in preceding slideway; Back teaching plate also can freely move up and down in rear slide; Thereby the teacher is in use, can with the teaching plate of writing move to the top, then below the teaching plate on then write; Be not only applicable to the teacher of various heights, and write slow classmate and can not omit learning content yet because of catching up with to take notes; In addition; Before ball in the circle chute that is provided with respectively of the edge of teaching plate and back teaching plate be connected with ruler, this ruler can move freely with ball, promptly can around preceding teaching plate or back teaching plate, move freely; Thereby realize ruler horizontal positioned or vertical the placement; Made things convenient for the usefulness of mathematics teacher's mapping, use is that school uses very desirable teaching aid very flexibly, conveniently.
