Digital film projector with safety protection effect

Abstract

The invention discloses a digital film projector with a safety protection effect, which comprises a protective shell, a protective door, a cooling mechanism, a protective cover, an adjusting mechanism, a support plate, a projector, an external thread ring and a projection debugging mechanism, and is characterized in that the protective door is connected to the protective shell through bolts, and the cooling mechanism is arranged on the protective shell; an external thread ring is fixedly connected to the outer side of the protective shell, a protective cover is connected to the external thread ring through threads, the protective cover makes contact with the protective shell, an adjusting mechanism is arranged on the protective shell, a supporting plate is fixedly connected to the interior of the protective shell, and a projector is installed on the supporting plate; the projector is in contact with the protective shell, and the protective door is provided with a projection debugging mechanism. The invention relates to a digital film projector with a safety protection effect. The digital film projector has the characteristics of being convenient to debug, convenient to adjust a placement angle and capable of preventing dust from influencing picture quality.

Description

technical field [0001] The invention belongs to the technical field of digital movie projectors, in particular to a digital movie projector with safety protection effect. Background technique [0002] The digital cinema machine applies the digital micromirror switch device DMD—digital optical switch array and digital signal processing technology, and adopts the new mode of digital film projection of the digital light processing technology DLP, which replaces the film image reproduction mode of the traditional film film projector, and realizes no film Projection, the projector needs to be protected by a protective device when it is in use, but there are some problems with the projector at present: 1. Because there is a protective shell on the outside of the projector, it is not convenient to debug the projector; 2. The protective shell cannot be adjusted according to the plane where it is placed. If the angle is adjusted, the projected picture will not be correct; 3. The dust...
