Abstract

The invention discloses a multimedia teaching object projector. The multimedia teaching object projector comprises a track moving structure, wherein a first rotating structure is arranged in a slidingmiddle part of the track moving structure; the lower end of the first rotating structure is detachably connected with a lifting adjusting structure; the lifting adjusting structure is slidably connected with a track; a first connecting structure is arranged below the lifting adjusting structure; and the first connecting structure is detachably connected with the projector. According to the multimedia teaching object projector, firstly, the track moving structure is arranged to realize the corresponding movement of the whole device along the track direction, so that a certain proportion of reduction or enlargement can be realized. Then, the projector is correspondingly adjusted in the horizontal direction through the first rotating structure, and then longitudinal adjustment is achieved through the lifting adjusting structure, so that the three-coordinate adjusting effect is achieved.

Description

technical field [0001] The invention relates to the technical field of teaching object projectors, and mainly relates to a multimedia teaching object projector. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. [0003] The existing projector is provided with a connecting rod, and the connecting rod is used to realize the corresponding lifting, so as to adjust the corresponding height. [0004] However, in the process of actual operation, the size of the corresponding projection screen can be adjusted due to the distance of the projector, the existing projector can only adjust the technical problem of the corresponding height. SUMMARY OF THE INVENTION [0005] The present invention provides a multimedia teaching object projector to solve the problem prop...
