Film screen capable of automatic fold

Abstract

The invention relates to a film screen capable of automatic fold. The film screen comprises a rear seat and a screen, wherein a left fixed plate and a right fixed plate are separately and fixedly connected with the rear side of the left part and the rear side of the right end of the screen, the upper end and the lower end of the rear part of the left fixed plate are separately hinged with a left connection rod, the upper end and the lower end of the rear part of the right fixed plate are separately hinged with a right connection rod, a central rod is arranged between the left connection rod and the right connection rod and is connected with rope pulleys and a pull spring, a rope tape is arranged between the rope pulleys, a fastening lock is fixedly arranged on the rope tape, a transverse groove is formed in the rear seat, and a ball crew is rotatably arranged at the rear end of the rear seat and is connected with a motor through a coupler. The film screen is high in automation; the functions of automatically folding and unfolding the screen are achieved by modes of lead screw nut transmission and rope pulley transmission, and a protection effect is exerted on the screen; and moreover, the visual effect of folding and unfolding the screen is high, the speed is relatively fast, and the time point of film showing is accelerated.

Description

technical field [0001] The invention relates to the technical field of film and television entertainment, in particular to an automatically retractable movie screen. Background technique [0002] With the improvement of our country's per capita material living standards, people's pursuit of entertainment enjoyment is increasing. As a cheap and affordable entertainment consumption place, cinemas are favored by most people today. In order to improve the protection of the movie screen and prevent the sound holes on the screen from being contaminated by dust in the air, after the movie is shown, the screen will be rewound by automatic winding to play a certain role in protection. But the disadvantage of this kind of winding is that one end of the screen needs to be wound on a certain shaft first, and then connected with the extension end of the shaft through a series of mechanical or electrical control devices to control the rotation of the shaft, so as to achieve automatic wind...

In order to improve the protection of the movie screen and prevent the sound holes on the screen from being contaminated by dust in the air, after the movie is shown, the screen will be rewound by automatic winding to play a certain role in protection. But the disadvantage of this kind of winding is that one end of the screen needs to be wound on a certain shaft first, and then connected with the extension end of the shaft through a series of mechanical or electrical control devices to control the rotation of the shaft, so as to achieve automatic winding and However, the disadvantage of this implementation is that the speed of opening and rewinding is too slow, and the mechanical or electrical control devices will be exposed, which will affect people's visual experience of watching movies.
