Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a projection device for electronic information technology teaching, including a mounting plate 1, an upper fixing frame 2, a lower fixing frame 3 and a projector 4, wherein the fixing frame 2 is welded on the bottom wall of the mounting plate 1, the lower fixing frame 3 is welded on one side of the bottom wall of the fixing frame 2, the lower fixing frame 3 is used for providing a mounting place for the projector 4, the projector 4 is mounted between the side walls of the lower fixing frame 3 through a fixing shaft, a mounting ring 41 is mounted on the outer portion of the projector 4 through a set screw, the mounting ring 41 is used for driving the projector 4 to adjust the angle, a fixing plate 21 is arranged at the bottom end inside the fixing frame 2, the fixing plate 21 is used for guiding and limiting the sliding seat 5, a sliding seat 5 is slidably arranged on the outer wall of the fixing plate 21, the sliding seat 5 is used for driving a linkage rod 6 to move and adjust, and the, and all weld the connecting seat between the bottom of slide 5 and the top of collar 41, there is the gangbar 6 through the key-type connection between two connecting seats, and the gangbar 6 is for driving collar 41 to adjust at the in-process that slide 5 removed, and inclination sensor has been inlayed on the surface of gangbar 6 for the convenience.

The fixing plate 21 is fixed between the inner walls of the upper fixing frame 2 by welding, the fixing plate 21 is in an I-shaped structure, the outer walls of two sides of the fixing plate 21 are respectively provided with a guide groove 22 meshed with the driving gear 51, the guide grooves 22 are used for guiding the driving gear 51, the sliding seat 5 is in an inverted 'concave' structure, and the driving gear 51 is arranged on the inner side of the sliding seat 5 through a fixing shaft; in addition, when the projector 4 is in the horizontal position, the linkage rod 6 is in the vertical state at the moment.
