Automatic teaching projection device

Abstract

The invention discloses an automatic teaching projection device, and particularly relates to the technical field of projection equipment. The automatic teaching projection device comprises a bottom plate, wherein a base is overlapped on the upper surface of the bottom plate; the upper surface of the base is fixedly connected with the lower surface of projection equipment; threaded rods are movablyconnected to the left side surface and the right side surface of the inner wall of the base through rotating assemblies; threaded caps are in threaded connection with the left side and the right sideof the outer surface of each threaded rod; and the lower surface of each threaded cap is fixedly connected with the upper surface of a connecting plate. According to the automatic teaching projectiondevice, the threaded rods, the threaded caps, the connecting plates, clamping teeth, gears, sleeve rods, pressing plates, the bottom plate, the base and the projection equipment are arranged, the twothreaded caps are far away from each other in the rotating process of the threaded rods, so that the two connecting plates drive the two clamping teeth to be clamped into the two gears correspondingly, then sleeves can be effectively limited, the device can be effectively folded and stored, teaching staff can conveniently carry the projection device and use the projection device at different places, and the applicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of projection equipment, and more specifically, the invention relates to an automatic teaching projection device. Background technique [0002] In the field of modern teaching, multimedia teaching means that in the teaching process, according to the characteristics of teaching objectives and teaching objects, through teaching design, rationally select and use modern teaching media, and organically combine with traditional teaching methods, and participate in the whole teaching process to achieve A variety of media information acts on students to form a reasonable structure of the teaching process and achieve the optimal teaching effect. [0003] In the field of automated teaching, projection devices are mostly used. Through large-screen projection, students can watch more clearly and intuitively. Most of the existing projection equipment is supported by a support frame. In order to maintain the stability of ...

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic teaching projection device. The technical problem to be solved by the present invention is: although the existing projection device can be adjusted to a certain extent, the support structure of the projection device is integrated and fixed. structure, the entire projection device cannot be effectively folded and stored, making it inconvenient for teaching staff to carry the projection device and use it in different locations
