Abstract
The utility model discloses a multifunctional three-view projector, comprising a front-view projecting plate, a left-view projecting plate and a top-view projecting plate which are arranged according to the three-view projecting relation. A dimension switching projecting plate used for displaying top-view and left-view dimension relation is arranged on the lower side of the left-view projecting plate. The multifunctional three-view projector can display not only the three-view projecting relation but also the top-view and left-view dimension relation, and can assist students to understand mutual projection relation among three views visually and more easily. Simultaneously, the multifunctional three-view projector can not only realize planar display but realize three-dimensional display, and further realizes convenient and fast mutual switching between the planar display and the three-dimensional display. When a teacher gives a lesson, the three-view projector can be adsorbed onto a blackboard, thereby reducing burden of the teacher. When the multifunctional three-view projector is not used, the all projecting plates are folded onto one plate, thereby bringing convenience for carrying and storage.

The utility model content
In view of this, the purpose of this utility model provides a kind of multi-functional three-view diagram projector, it can show the three-view diagram projection, can show vertical view and left view annexation again, say that class hour can be attracted on the blackboard, and the time spent can not fold into all projection plates on the plate, carries, deposit convenience.
The multi-functional three-view diagram projector of the utility model, comprise front view projection plate, left view projection plate and the vertical view projection plate arranged by the three-view diagram projection relation, described left view projection plate below is provided with the size conversion projection plate that is used to show vertical view and left view size relationship;
Described front view projection plate and left view projection plate are hinged by hinge I in the mode that can rotate in the plane perpendicular to adjacent long edges,
Described front view projection plate and vertical view projection plate are hinged by hinge II in the mode that can rotate in the plane perpendicular to adjacent long edges,
Described size conversion projection plate and left view projection plate are hinged by hinge III in the mode that can rotate in the plane perpendicular to adjacent long edges.
Further, the back side of described front view projection plate, left view projection plate and vertical view projection plate is set with magnetic chuck I, and the front of described size conversion projection plate is set with magnetic chuck I.
Further, described vertical view projection plate right hand edge is set with magnetic chuck II, described left view projection plate lower limb be provided with can with the magnetic chuck III of the corresponding absorption of magnetic chuck II.
Further, its part that is arranged on the front view projection plate of described hinge II has waist shape chute, and the long limit of described waist shape chute is perpendicular to adjacent with it projection plate edge, and described front view projection plate is being riveted on the hinge along the mode that waist shape chute slides.
The beneficial effects of the utility model: the multi-functional three-view diagram projector of the utility model, it can show the three-view diagram projection relation, can show vertical view and left view size relationship again, can help student's mutual projection relation that is more readily understood between three-view diagram more directly perceived; This multi-functional three-view diagram projector not only can be done the plane displaying but also can do solid show simultaneously, and the plane is showed and solid show is changed convenient and swift mutually; Say that the multi-functional three-view diagram projector of class hour basis can be attracted on the blackboard, can alleviate teacher's burden, the time spent can not fold into all projection plates on the plate, carries, deposits conveniently.
