Abstract

The invention discloses a digital film projection device. The digital film projection device comprises a base. The top of the base is rotationally connected with a device box through a stand column. One side of the stand column is fixedly connected with a fixed block. The fixed block is slidably provided with an inserting rod in an inserted mode. A plurality of inserting grooves corresponding to the inserting rod are formed in the top of the base in a surrounding mode. A fixed rod is fixedly connected with the end, away from the base, of the inserting rod. The end, away from the inserting rod,of the fixed rod is connected with the fixed block through a telescopic rod. A first spring is arranged on the telescopic rod in a sleeving mode. The two ends of the first spring are fixedly connected with the fixed rod and the fixed block correspondingly. The device box is internally and rotationally connected with a threaded rod. The threaded rod is fixedly connected with a first gear in a sleeved mode. The device box is internally provided with a second gear meshing with the first gear. According to the digital film projection device, through the arrangement of multiple adjusting mechanisms, the projection device can be adjusted freely according to an actual projection site, so that the playback effect of a digital film is ensured, and the viewing experience of people is enhanced.

Description

technical field [0001] The invention relates to the technical field of digital cinema equipment, in particular to a digital cinema projection device. Background technique [0002] Digital film refers to a film in which digital processing technology is used to replace traditional optical chemical or physical processing technology in part or all, and digital media replaces film in film shooting, post-processing, distribution and projection. Compared with traditional film films, digital films The advantages are mainly reflected in the saving of film production costs, the innovation of production methods, and the improvement of production standards. Through high-definition camera technology, it has realized the connection with the high-definition era; digital media storage can always maintain stable quality without any wear and tear. There will be no jitter and flicker; transmission and distribution do not require film development, the distribution cost is greatly reduced, and t...
