Problems solved by technology

The projector projection display device or imaging capture device must use the lens to complete optical imaging, so the lens needs to be maintained in daily use to ensure the projection effect. Similarly, a reflector for reflecting light is installed inside the projector , the light is reflected by the reflector and then emitted through the lens. In order to improve the projection effect, it is necessary to adjust or maintain the reflector inside the projector. When repairing or maintaining the projector, there are non-staff who forget to turn off the projector. Phenomenon of power supply, there are potential safety hazards

Abstract

The invention belongs to the technical field of projectors and relates to a safety protection system which comprises a shell, a sealing cover is detachably connected to the shell, a plurality of reflectors used for reflecting projection light are arranged in the shell, a shielding assembly used for shielding the projection light is arranged in the shell, the shielding assembly is arranged between the reflectors, a proximity switch used for controlling the shielding assembly is arranged on the shell, the proximity switch and the sealing cover are arranged in a spaced mode, a first metal block used for controlling the proximity switch is arranged on the sealing cover and corresponds to the proximity switch, and a standby assembly used for controlling the proximity switch is arranged on the shell. According to the safety protection system, the safety of a projector can be improved.

Description

technical field [0001] The present application relates to the technical field of projectors, in particular to a security protection system. Background technique [0002] A projector is a device that can project images or videos onto a screen. It can be connected to computers and other devices through different interfaces to play corresponding signals. It is widely used in homes, offices, schools and entertainment places. The projector projection display device or imaging capture device must use the lens to complete optical imaging, so the lens needs to be maintained in daily use to ensure the projection effect. Similarly, a reflector for reflecting light is installed inside the projector , the light is reflected by the reflector and then emitted through the lens. In order to improve the projection effect, it is necessary to adjust or maintain the reflector inside the projector. When repairing or maintaining the projector, there are non-staff who forget to turn off the projec...
