Abstract
The utility model discloses a three-view projection teaching apparatus which comprises three projection plates that are hinged into one by using hinging parts. The three-view projection teaching apparatus is characterized in that a projection plate located on a horizontal projection surface is fixed on the upper surface of a base plate, the upper surface of the base plate and the outer sides at four side surfaces of the projection plate are provided with a continuous sliding chute, a slide block sliding along the sliding chute is arranged in the sliding chute, the bottom end of a vertical rod is fixed on the slide block, the top end of the vertical rod is connected with a horizontal rod, the horizontal rod is located above the projection plate on the horizontal projection surface, and a projection lamp is sleeved on the horizontal rod and the vertical rod and slides along the horizontal rod and the vertical rod. The three-view projection teaching apparatus has a simple structure; in use of the teaching apparatus, a variety of views can directly projected on the projection plate through usage of the projection lamp, which is convenient for development of view projection teaching and can substantially improve perceptual cognitive capability.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of Three-view projection instructional device.
Background technology
At present, the machinery of all kinds of ordinary higher learning schools of China, vocational technical universities and colleges and skilled workers school and nearly mechanical speciality adopt the fixed three-view drawing projection teaching board of a plate one to impart knowledge to students in mechanical drawing teaching.When making, all be decorated with view on three inner faces of one cover teaching aid board, and must with just can support the use after the corresponding a kind of solid wooden model entity of its view is connected with iron wire.
Have more than 30 to plant commonly used, typical legend and should use teaching aid board to impart knowledge to students on the mechanical drawing teaching material, but the teaching aid board that provides on the market is less than 15 kinds, kind is complete, lazy weight.In this case, a lot of schools can only be less with or impart knowledge to students without teaching aid board, greatly affected the quality of instruction of Mechanical Drawing Taught and the further ability of raising student perceptual knowledge.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and is convenient to view projection teaching, improves the Three-view projection instructional device of student's perceptual knowledge ability.
In order to reach above purpose, the technical scheme that the utility model adopts is: this Three-view projection instructional device, comprise three projection plates, adopt articulated manner to connect as one by hinge member between the projection plate, it is characterized in that: the projection plate that is positioned at horizontal plane is fixed on the upper surface of base plate, simultaneously the upper surface of base plate and the outside that is positioned at projection plate four sides are provided with continuous chute, in chute, be provided with the slide block that slides along chute, vertically the bottom of bar is fixed on the slide block, vertically the top of bar is connected with horizon bar, horizon bar is above the projection plate that is positioned at horizontal plane, projection lamp is enclosed within on horizon bar and the vertical bar, and along horizon bar and vertically bar slip.
The beneficial effects of the utility model are: simple in structure, utilize during use projection lamp can be directly on projection plate projection form various views, be convenient to carrying out of view projection teaching, can greatly improve student's perceptual knowledge ability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, projection plate; 2, hinge member; 3, horizon bar; 4, vertical bar; 5, projection lamp; 6, slide block; 7, chute; 8, base plate.
Embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing.This Three-view projection instructional device, comprise three projection plates 1, adopt articulated manner to connect as one by hinge member 2 between the projection plate 1, when projection plate 1 is folded to three blocks of plates and is orthogonal state, namely consisted of Three-view projection face V, H, W, need the component of machine of projection to be held in place on the projection plate 1 of horizontal plane, it is characterized in that: the projection plate 1 that is positioned at horizontal plane is fixed on the upper surface of base plate 8, simultaneously the upper surface of base plate 8 and the outside that is positioned at projection plate 1 four sides are provided with continuous chute 7, in chute 7, be provided with the slide block 6 that slides along chute 7, vertically the bottom of bar 4 is fixed on the slide block 6, vertically the top of bar 4 is connected with horizon bar 3, horizon bar 3 is above the projection plate 1 that is positioned at horizontal plane, and projection lamp 5 is enclosed within on horizon bar 3 and the vertical bar 4, and along horizon bar 3 and vertically bar 4 slips.When projection lamp 5 was arranged on the vertical bar 4, slide block 6 slided along chute 7, drove vertical bar 4 and slided with the projection lamp 5 that is enclosed within on the vertical bar 4, made projection lamp 5 carry out light projection in all angles of surface level; When projection lamp 5 is arranged on the horizon bar 3, can realize the in the horizontal direction light projection on projecting plane of parts by projection lamp 5.
