Embodiment 1

[0043] A screen black frame system, such as figure 1 As shown, it includes an upper black border device 4 and a double-layer side black border device 3 fixed on the front of the screen 2 in sequence. The upper black border device 4 includes an upper black border 46 and an upper black frame 44. The upper black border 46 Wrapped on the upper black frame 44; the upper black frame 44 can move up and down in the vertical direction; by wrapping the upper black frame on the surface of the upper black frame and moving in the vertical direction of the upper black frame to realize the change of the screen state, the upper screen facing the audience The black border completely covers the upper black border and the fixed rope behind the frame, and the audience in the front row will only see the flat upper black border on the upper black border when watching movies, without affecting the viewing effect. The double-layer side black frame device 3 comprises 2 outer layer black frames 38 fixe...

Embodiment 2

[0045] A kind of screen black frame system of the present embodiment, basic structure is the same as embodiment 1, and the improvement is: as Figure 4 As shown, the upper black frame 44 is connected to the fixed pulley 41 through the lead wire 42 to realize the vertical movement up and down; the fixed pulley 41 is fixed on the upper surface of the far end of the middle vertical rod 14 fixed on the upper part of the screen frame 1, and is realized through the cooperation of the fixed pulley and the lead wire. The vertical movement of the upper black frame is easy to operate and runs smoothly; figure 2 As shown, the relative movement and reverse movement of the inner layer black frame 33 are realized by driving one inner layer black frame 33 respectively through two traction mechanisms 32, and the traction mechanism 32 includes a pulley 321 and a connecting rod 322; The end face is fixedly connected with the bottom end of the connecting rod 322, and the other end of the connec...

Embodiment 3

[0047] A kind of screen black frame system of this embodiment, the basic structure is the same as embodiment 2, and the improvement is that: double-layer side black frame device 3 also includes steel wire 36; Connection; the middle part of the steel wire 36 is connected with the pulley motor, so that the two inner layers of black frames can run synchronously, so as to prevent the projection device from adapting to the size change of the screen by adjusting the angle; Fixed and positioned.

[0048] A kind of screen state switching method of this embodiment, the operation steps are:

[0049] Step 1: Maximize the screen, start the motor of the fixed pulley 41, when the motor rotates clockwise, the fixed pulley 41 will drive the lead wire 42 to rotate together, and the lead wire 42 will be wound on the fixed pulley 41 circle by circle, at this time the black border 44 moves upward under the traction of lead wire 42, and upper black border 46 is slowly packed up to the top; at the...

Abstract

The invention discloses a screen black frame system and a screen state switching method, and belongs to the technical field of film screens. The system comprises an upper black edge device fixed in front of the upper part of a screen and a double-layer side black edge device fixed at a side front part. The upper black edge device comprises an upper black edge and an upper black frame, wherein the upper black edge covers the upper black frame. The upper black frame can move up and down in a vertical direction. The double-layer side black edge device comprises two outer layer black frames fixed at a side front of the screen, and two inner layer black frames fixed between the screen and the outer layer black frames. The two inner layer black frames can make relative motion towards the central part in a horizontal direction, or make reverse motion towards two sides. The main purpose of the system is that the upper black frame can move up and down in the vertical direction through the fixing of the upper black edge of the upper black frame, and the double-layer side black edges make movement in the horizontal direction, thereby achieving the switching of the screen states, and optimizing the watch effect.

Description

technical field [0001] The invention relates to the technical field of movie screens, and more specifically, to a screen black frame system and a screen state switching method. Background technique [0002] Movies are an indispensable form of entertainment for people in modern society. Movie projections are projected onto the screen through a projection device. Therefore, the screen is one of the essential projection equipment. Moreover, due to the needs of optical principles, black borders are generally set on the edge of the screen. However, with the development of projection technology With continuous development, due to the needs of screen flatness and viewing effect, the black border of the screen is no longer integrated with the screen, but the black border is fixed on the front side of the screen. [0003] At present, the main disadvantage of the electric upper black bezel in cinemas is that it takes up a lot of space, and the upper black bezel is too far away from t...
