Problems solved by technology
[0005] In view of the above problems, the present invention provides a protective device for a suspended projector with a heat dissipation function. The protective device can not only provide dustproof protection for the suspended projector, but also can be opened during the operation of the projector to avoid affecting the projection. The heat dissipation in the instrument solves the problem that the existing protection device cannot solve the problem of dust prevention and heat dissipation at the same time

The invention discloses a suspension type projector protection device with a heat dissipation function. The suspension type projector protection device comprises a front panel, a convex plate, a machine shell, a pushing mechanism, a baffle, a flexible layer, a mounting frame, a dustproof shell and a telescopic mechanism. The convex plate is fixed on the front panel, and the convex plate and the front panel are provided with aligned lens holes. The machine shell is fixed to the front panel and located on one side of the protruding plate. The pushing mechanism is fixed in the machine shell, the baffle is connected with a push rod of the pushing mechanism, the flexible layer is fixed to the inner side face of the baffle, and the thickness of the flexible layer is larger than the width of a gap between the inner side face of the baffle and the protruding plate. And the front panel is detachably fixed at the front end part of the mounting frame. The dustproof shell is composed of four L-shaped plates which are arranged on the four edges of the two sides of the installation frame respectively, and the dustproof shell is connected with the edges of the installation frame through the telescopic mechanisms which are arranged in the inclined direction. The protection device solves the problem that an existing protection device cannot achieve dust prevention and heat dissipation at the same time.
Description
technical field [0001] The invention relates to the technical field of projectors, in particular to a hanging projector protection device with heat dissipation function. Background technique [0002] A projector is a multimedia device that can project images or videos in the computer onto the screen, which provides convenience for multimedia teaching. Teachers can project teaching materials, videos, etc. through the projector onto the screen for students to display conveniently. With the help of bright and vivid pictures, it is not only easy for students to understand the teaching content, but also helps to inspire students' thinking and improve the teaching effect. [0003] At present, the suspended projector is hung on the roof of the classroom through a fixed pole, turned on by a remote control when in use, and turned off after use. However, the classroom is different from other usage environments. On the one hand, the doors and windows of the classroom are often opened ...
