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. Based on the embodiments in the present invention, all other embodiments obtained by the staff of ordinary skill in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides an interactive multimedia projection equipment, includes box 1, the top of box 1 is provided with step top 2, opening 3 has been seted up on step top 2, be provided with convex lens 4 in the opening 3, box 1's inside top fixed mounting has opening 3, box 1's inside fixed mounting has third speculum 14 and projecting apparatus subassembly 15, box 1's lateral wall top movable mounting has first picture frame 8, first picture frame 8 has first speculum 9 in one side fixed mounting who is close to opening 3.

In this embodiment, embedded internal thread pipe 5 of installing in one side top of box 1, threaded rod 6 is installed in the inside screw-thread fit of internal thread pipe 5, and the one end fixed mounting of threaded rod 6 has knob 7, and the other one end of threaded rod 6 is rotated and is installed the bottom at first picture frame 8.

In this embodiment, the both sides of first picture frame 8 have been seted up spout 10, and the both sides of box 1 are provided with the stopper, and stopper slidable mounting is in spout 10.

In this embodiment, the positional relationship among the first reflecting mirror 9, the convex lens 4, the third reflecting mirror 14, and the projector assembly 15 should satisfy: when the projector assembly 15 is turned on, the light source generated by the projector assembly 15 can pass through the convex lens 4 to the first reflecting mirror 9 by the reflecting action of the third reflecting mirror 14 and the projector assembly 15.
