Abstract
The invention discloses a kind of Three-views teaching aid, it is related to teaching aid technical field；It includes bottom plate, multiple side plates and projection lamp, and the bottom plate side is connected with the fixing groove of height and equal length by connector, and multiple side plates are slipped by the flange of bottom surface with the fixing groove；The side board edge is provided with the top of geometrical clamp, the geometrical clamp and is provided with column, and the column is hinged with stock, and the projection lamp is socketed on the stock, and can be moved along the stock.Compared with prior art, the invention provides a kind of objects projection that can obtain so as to Three-views teaching aid of the mapper with reference to mapping.
Description
Technical field
The present invention relates to teaching aid technical field, especially a kind of Three-views teaching aid.
Background technology
The drafting of three-view diagram is one of important course of mechanical drawing, is also the basis of the contents such as sectional view and part drawing,
There is critically important status in the study of mechanical drawing；Three-view diagram is can correctly to reflect the positive throwing of object length size
Shadow engineering drawing, it include front view, three views of top view and left view, represent observer from front, above and three, the left side
Different angles observe perspective view obtained from same space geometric from, and this is also that engineering circles are sanctified by usage to geometry of objects
Abstract expression mode.Three-view diagram needs that the object being observed first is resolved into several bodies when drawing, and analyzes these
The combination and correlation of body, then draw the perspective view of each body one by one again；Due to limited conditions, three-view diagram exists
During drafting, the actual three-plane projection's figure of object does not depend on greatly the space knot that mapper is envisioned as object as reference
Structure, then three-view diagram is made by the spatial thinking ability of itself, when object structures complexity or weaker mapper's thinking ability,
It will have no way of doing it, it is impossible to draw out correct three-view diagram.
The content of the invention
It is an object of the invention to provide a kind of objects projection that can obtain so as to Three-views teaching aid of the mapper with reference to mapping.
In order to solve the above problems, the technical solution adopted by the present invention is：This Three-views teaching aid, including it is bottom plate, multiple
Side plate and projection lamp, the bottom plate side are connected with the fixing groove of height and equal length, multiple side plates by connector
Slipped by the flange and the fixing groove of bottom surface；The side board edge is provided with the top of geometrical clamp, the geometrical clamp and is provided with column,
The column is hinged with stock, and the projection lamp is socketed on the stock, and can be moved along the stock.
In above-mentioned technical proposal, more specifically technical scheme can also be：The connector is magnet or VELCRO.
Further, the side plate is provided with groove and the box being placed in the groove, the box bottom one
Lateral edges are hinged by bearing pin with the groove.
Further, the glove box outer surfac is provided with attacker.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the object for needing to draw is positioned over above bottom plate, opens projection lamp, and by geometrical clamp in two side board edges
It is mobile, and projection lamp, in the movement of stock, the front view and left view that object can be just obtained in two side plates are projected, and the bottom of at
Plate obtains top view projection, and illustrator is obtained more, intuitively view effect is referred to, and conveniently draws out accurate three face
Perspective view.
2nd, side plate can be taken out from fixing groove, and two side plates and bottom plate are superimposed together, and convenient for collecting and be occupied little space.
3rd, be the bottom plate and side plate of square using surface, enable the view that is projected out conveniently, accurate slide ruler
Very little and scaling；Box is painted by operating attacker to outwardly open for placing pencil, ruler, rubber and compasses etc.
Figure instrument, facilitates illustrator to use；Box can be arranged as required in any one or more side plates.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention 1；
Fig. 2 is Fig. 1 left view；
Fig. 3 is Fig. 2 top view.
Embodiment
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
Embodiment 1：
This Three-views teaching aid as shown in Figure 1, Figure 2 and Figure 3, including bottom plate 1, two side plates 2 and projection lamp 3, bottom plate 1 and side
The intersecting face of plate 2 is the equal square of the length of side, and bottom plate 1 leads in the side of front view projecting direction and left view projecting direction
The fixing groove 4 that magnet is connected with height and equal length is crossed, two side plates 2 are slipped by the flange of bottom surface with fixing groove 4；Wherein
Geometrical clamp 5 of one edge of side plate 2 provided with activity, the top of geometrical clamp 5 is provided with column 6, and column 6 is hinged with stock 7, projection lamp 3
It is socketed on stock 7, and can be moved along stock 7；Groove 8 is provided with positioned at the side plate 2 of front view projecting direction and is placed on groove 8
Interior box 9, the bottom side edge of box 9 is hinged by bearing pin with groove 8, and the outer surface of box 9 is provided with attacker 10.
In use, the object for needing to draw is positioned over into the top of bottom plate 1, projection lamp 3 is opened, and by geometrical clamp 5 two
The movement at the individual edge of side plate 2, and projection lamp 3 can just obtain front view and a left side for object in the movement of stock 7 in two side plates 2
View projections, and top view projection is obtained in bottom plate 1, illustrator is obtained more, intuitively view effect is referred to, side
Just accurate three-plane projection drawing is drawn out.
When not in use, geometrical clamp is removed from the edge of side plate 2, then two side plates 2 is taken out from fixing groove 4, then by two
Side plate 2 and bottom plate 1 are superimposed together, and convenient for collecting and occupy little space.
The use of surface is the bottom plate 1 and side plate 2 of square, enable the view that is projected out conveniently, accurate slide ruler
Very little and scaling.Box 9 is by operating attacker 10 to outwardly open, for placing pencil, ruler, rubber and compasses etc.
Drawing instrument, facilitates illustrator to use.Box 9 can be arranged as required in any one or more side plates.
Embodiment 2：
Side plate 2 and fixing groove 4 are four, and the side of bottom plate 1 is connected with the fixing groove of height and equal length by VELCRO
4, further feature is same as Example 1.
The Three-views teaching aid of this embodiment can be used for the six faces projection for obtaining material object.
