Projection equipment for multifunctional rotary teaching platform for art education

Abstract

The invention relates to the related technical field of multimedia teaching, and discloses projection equipment for an art education multifunctional rotating teaching platform. The equipment comprises a shell, the outer side of the shell is provided with an air inlet duct communicated with the inner cavity of the shell, the side wall of the shell is provided with an air outlet duct for discharging airflow in the inner cavity of the shell, the air outlet duct is provided with an air outlet groove, a projection lens located on one side of the air outlet channel is fixedly installed on the side wall of the shell, and a dustproof plate used for shielding the air outlet channel and the projection lens is hinged to the top of the side wall of the shell. According to the equipment, the dustproof plate is hinged to the shell, the air outlet channel communicated with the inner cavity of the shell is formed in the shell, when the projection lens is used, the dustproof plate is lifted through air flow blown out of the air outlet channel, and normal imaging of the projection lens is achieved; and meanwhile, according to the air flow intensity of the air flow blown out of the air outlet channel, whether the air inlet duct is blocked or not can be obviously seen, and finally the purposes of autonomously protecting the projection lens and monitoring blocking in real time are achieved.

Description

technical field [0001] The invention relates to the technical field related to multimedia teaching, in particular to a projection device for a multifunctional rotating teaching table for art education. Background technique [0002] The projection device is a device that projects images or videos onto the screen, and by adding a rotating adjustment table at the bottom, the projector can also be rotated and projected, so that multiple positions can be used as the projection subject. [0003] In the process of using the existing projection equipment, after the projection equipment is fixed, the protective lens kit is taken out, and the fan in the projector is connected to the circuit to realize the cooling in the fan. And realize imaging through projection lens. [0004] However, in the actual use process, since the protective lens kit is mostly installed separately, it is easy to cause the protective kit to be lost after use, and the integrated protective kit can solve the pr...
