Abstract
The invention relates to a teaching appliance, and particularly relates to a three-view projection teaching appliance. The three-view projection teaching appliance comprises a bottom plate. The three-view projection teaching appliance is characterized by further comprising a groove-type main view projection plate which comprises a lower plane, a vertical surface and an upper plane. The bottom plate is provided with a top view projection plate. One side of the bottom plate is hinged with the lower plane. The left side of the vertical surface is hinged with a left view projection plate. The bottom plate is provided with an L-shaped slide groove which is internally provided with a connecting base sliding along the L-shaped slide groove. The connecting base is provided with an inverted L-shaped telescopic rod which is sleeved by a projection lamp. The left edge of the bottom plate and the bottom end surface of the left view projection plate are provided with an iron sheet and a magnet sheet which are correspondingly attracted. The vertical surface has a hollow structure. The vertical surface is internally provided with a projection conversion plate capable of being rightward extracted and pulled. Stereo projection relationships can be vividly and visually displayed, mutual conversion between plane display and stereo display is convenient and rapid, and all the projection plates can be folded on the bottom plate when the three-view projection teaching appliance is not used so that carrying and storage are convenient.
Description
(1)
Technical field
The present invention relates to a kind of teaching aid, particularly to a kind of Three-view projection teaching aid.
(2)
Background technology
At present, in the mechanical drawing three-view diagram teaching of the mechanical and mechanical relevant speciality of all kinds of vocational technical universities and colleges in the whole nation and vestibule school, substantially teacher uses three-view diagram model made of paper or the single projection model of structure to carry out instruction formula teaching, for the student of initial contact mechanical drawing, it cannot be made quickly to form a perceptual cognition, leverage the quality of instruction of Mechanical Drawing Taught, and three-view diagram is the basis of mechanical drawing study, once this content does not succeed in school, the systematic learning of course below will be had influence on, student is made to lose the interest of study.
(3)
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of can intuitively, lively, be readily achieved the Three-view projection to model, and Three-view projection teaching aid easy to carry.
The present invention is achieved through the following technical solutions:
A kind of Three-view projection teaching aid, including base plate, it is characterized in that: also include grooved front view projection plate, described grooved front view projection plate includes lower plane, facade and upper plane, described base plate is provided with the top view projection plate being parallel to base plate, the hinged lower plane in described base plate side, hinged left view projection plate on the left of described facade, described base plate is provided with L-shaped chute, the connection seat along L-shaped slide it is provided with in described L-shaped chute, described connection seat is provided with inverted L-shaped expansion link, sheathed projecting lamp on described inverted L-shaped expansion link, described projecting lamp can rotate along inverted L-shaped expansion link.
Described base plate left hand edge and left view projection plate bottom face are provided with can the corresponding iron plate adsorbed and flat thin magnet.
Described facade is hollow structure, and being provided with inside described facade can the projection transform plate of pull to the right.
Described base plate and upper plane are provided with the lockset matched.
The invention has the beneficial effects as follows:
The present invention not only can do laid out flat but also can do solid show, and laid out flat is mutually changed convenient and swift with solid show；All projection plates can not folded on base plate by the used time, carries, deposits conveniently.The present invention is simple to operate, the most intuitively, facilitates teacher to tell about the projection relation of project objects figure.

Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the perspective view of the present invention；
Accompanying drawing 2 is structural representation during laid out flat of the present invention；
Accompanying drawing 3 is the structural representation after present invention folding；
Accompanying drawing 4 is the sectional structure schematic diagram of grooved front view projection plate.
In figure: 1 base plate, 2 downward projection plates, 3 left view projection plates, 4 grooved front view projection plates, 5 projection transform plates, 6 locksets, 7 iron plates, 8 flat thin magnets, 9L shape chute, 10 connect seat, 11 inverted L-shaped expansion links, 12 projecting lamps, 13 lower planes, 14 facades, plane on 15.

Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.Such as Fig. 1, 2, 3, shown in 4, a kind of Three-view projection teaching aid, including base plate 1, also include grooved front view projection plate 4, grooved front view projection plate includes lower plane 13, facade 14 and upper plane 15, lower plane 13 side consolidation facade 14, the upper plane 15 of facade 14 other end consolidation, lower plane 13 and upper plane 15 are each perpendicular to facade 14 and are positioned at the same side of facade 14, base plate 1 is provided with the top view projection plate 2 being parallel to base plate 1, the hinged lower plane in base plate 1 side 13, hinged left view projection plate on the left of facade 14, facade 14 is hollow structure, facade 14 is internal, and be provided with can the projection transform plate 5 of pull to the right, base plate 1 left hand edge and left view projection plate 3 bottom face are provided with can the corresponding iron plate 7 adsorbed and flat thin magnet 8.Base plate 1 and upper plane 15 are provided with the lockset 13 matched.
When projection relation is changed to solid show by laid out flat, left view projection plate 3 rotates 90 ° relative to grooved front view projection plate 4 perspective plane, projection transform plate 5 pushes in facade 14 to the left, left view projection plate 3 can make iron plate 7 and flat thin magnet 8 be attached together after rotating 90 °, is conducive to keeping stablizing of three-view projector.Conversion between laid out flat and solid show is efficient and convenient, is conducive to teaching.Lockset 6 it is provided with between base plate 1 and upper plane 15.After teaching terminates, projection transform plate 5 is pushed in facade 14, left view projection plate 3 is positioned on grooved front view projection plate 4, after grooved front view projection plate 4 perspective plane rotates 90 °, the cavity surrounded, grooved front view projection plate 4 can be laminated on base plate 1 after rotating respective angles, and lock with lockset 6, carry and deposit conveniently.
Base plate 1 is provided with L-shaped chute 9, L-shaped chute 9 while be perpendicular to grooved front view projection plate 4, another side is parallel to grooved front view projection plate 4, the connection seat 10 slided along L-shaped chute 9 it is provided with in L-shaped chute 9, connect seat 10 and be provided with inverted L-shaped expansion link 11, sheathed projecting lamp 12 on inverted L-shaped expansion link 11, on the bar of the horizontal direction that projecting lamp 12 is positioned at inverted L-shaped expansion link 11, projecting lamp 12 can rotate along inverted L-shaped expansion link 11.
First regulation connects the seat 10 position in L-shaped chute 9, then rotate projecting lamp 12 and regulate the horizontal length of inverted L-shaped expansion link and vertical length, thus regulate the position of projecting lamp 12, open projecting lamp 12, being irradiated on object, so projection thing reflects by being projected in the projection paper on projection plate, and the projection paper on desirable nutation view projections plate 2 is put on projection transform plate 5 according to certain rule, so make three-view diagram in same level, it is simple to observe.
