Abstract

The utility model provides a projection model relates to teaching technical field how much, including the center piece, and evenly be equipped with around the center piece a plurality of center piece sliding surface's sliding block, the utility model discloses simple structure, the cost of manufacture is low, obtains different geometry through the slip, however the projected striking resemblances of plan view let projection among the more audio -visual solid geometry of understanding of student.

Description

Projection model

Technical field

This utility model relates to several teaching technical field, is specifically related to a kind of projection model.

Background technology

In the teaching process of solid geometry, it is typically all teacher on blackboard, explains the knowledge of solid geometry by the mode of plan Drawing to student. for the student just contacting solid geometry, just start brain and sometimes can't form the thinking of space structure, to point simple with plane geometry, line, face also fails to skillfully apply in space multistory geometry flexibly, to such an extent as to student feels gruelling when study solid geometry, do not understand these figures are how to be developed by solid figure, form confusion of thinking, do not catch up with thinking and rhythm that teacher teaches, and solid geometry, comparatively abstract, teacher at school time can take several stereomodels show to classmates, it is easy to classmates and has visual understanding, but owing to solid is more and compares heavy, not readily portable, often band is incomplete, also it is easier to break, have impact on teaching.

Utility model content

For the deficiencies in the prior art, this utility model provides a kind of projection model, simple, directly perceived, readily appreciate.

For realizing object above, this utility model is achieved by the following technical programs:

A kind of projection model, including central block, and is provided with some sliding shoes slided on described central block surface evenly around at described central block.

Further, described central block is cuboid.

Further, described sliding shoe is cuboid.

Further, four sides of described central block are equipped with chute, and described chute is strip opening, and inside is cuboid slideway.

Further, one of them side of described sliding shoe is provided with connecting rod, is provided with and the slide block of described cuboid slideway equal sizes bottom described connecting rod.

Further, the length of described connecting rod and described strip opening deep equality.

Further, described sliding shoe is provided with four, is slidably connected in the chute of described central block each through slide block.

Further, described slide block is made up of elastomeric material.

This utility model provides a kind of projection model, and by arranging central block, central block is arranged around some sliding shoes, sliding shoe slides the three-dimensional shape obtaining being ignorant of on central block, but top view or constant, such can aid in help student and understand, solid geometry.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is this utility model structural representation;

Fig. 2 is the structural representation of this utility model central block;

Fig. 3 is the structural representation of this utility model sliding shoe.

Wherein, 1, central block; 2, sliding shoe; 3, chute; 4, connecting rod; 5, slide block.

Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

In conjunction with accompanying drawing 1, Fig. 2 and Fig. 3, this utility model one projection model, including central block 1, and it is provided with some sliding shoes 2 slided on described central block 1 surface evenly around at described central block 1;

Central block 1 is cuboid, sliding shoe 2 is also for cuboid, four sides of central block 1 are equipped with chute 3, described chute 3 is strip opening, inside is cuboid slideway, one of them side of described sliding shoe 2 is provided with connecting rod 4, it is provided with bottom connecting rod 4 and the slide block 5 of described cuboid slideway equal sizes, the length of connecting rod 4 and described strip opening deep equality, sliding shoe 2 is provided with four, being slidably connected in the chute 3 of described central block 1 each through slide block 5, slide block 5 is made up of elastomeric material, improves frictional force.

It should be noted that, in this article, the relational terms of such as first and second or the like is used merely to separate an entity or operation with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially. And, term " includes ", " comprising " or its any other variant are intended to comprising of nonexcludability, so that include the process of a series of key element, method, article or equipment not only include those key elements, but also include other key elements being not expressly set out, or also include the key element intrinsic for this process, method, article or equipment. When there is no more restriction, statement " including ... " key element limited, it is not excluded that there is also other identical element in including the process of described key element, method, article or equipment.

Above example only in order to the technical solution of the utility model to be described, is not intended to limit; Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
