Abstract

The invention relates to a projection window structure for a movie theatre. The projection window structure comprises a wall body, a projection window and a protection cover, wherein the protection cover comprises a connecting part and a cover body part, the size of the connecting part is matched with the size of the projection window, the cross section of the cover body part is in a trapezoidal hollow structure, in addition, a sound isolation material layer is arranged on the inner wall of the cover body part, an annular clip is arranged on the inner wall at the narrow opening part of the cover body part, the diameter of the annular clip is slightly greater than a camera lens of a projection machine, and in addition, soft hair is fixedly arranged on an inner ring of the annular clip. The projection window structure has the advantages that projection light beams can reduce the light leakage in the spreading process, the influence of interference light generated by illuminating lamps on projection light rays in a projection room is also reduced, and the noise generated by a theatre hall and the projection room in the projection process can be effectively isolated.

Description

technical field [0001] The invention relates to a device for a cinema, in particular to a projecting window structure for a cinema. Background technique [0002] In existing theaters, there is usually a projection window between the viewing hall and the projection room, which is widely used in theaters. The isolation between the viewing hall and the projection room plays the role of sound insulation and fire prevention. Such as figure 1 As shown, the existing projection window is usually embedded with voltaic glass for projecting light to pass through, and there are sealing strips and sound-absorbing materials for lining and sound-absorbing materials between the voltaic glass and the window, so as to minimize the equipment work in the projection room When noise is generated, the projection effect will be damaged. In order to prevent fire, a fireproof glass is provided on one side of the Fufa glass. However, the setting of fire-resistant glass affects the brightness of proj...
