Description

Technical Field

[0001] This utility model relates to the field of COB cinema screen technology, and in particular to an easily adjustable COB cinema screen. Background Technology

[0002] COB displays, or chip-on-board displays, are a type of display where LED chips are directly packaged onto a PCB board. Through specific packaging processes, a fully sealed pixel structure is achieved, giving COB displays excellent stability and image quality.

[0003] A search revealed Chinese patent application number 202322598987.9, which discloses "a COB-packaged LED display screen, comprising a display screen support component, a display screen sealing component, fixing screws, and a COB-packaged imaging component. The display screen support component includes a screen frame with a slot on the front side. The display screen sealing component includes a through-plate frame with a through-plate on the inner side, a sealing ring on the rear side, and a retaining strip on the rear side of the sealing ring." However, when using this COB-packaged LED display screen in cinemas, the height of the screen needs frequent adjustment due to the frequent changes in seat heights. Since the COB-packaged LED display screen is directly mounted on the wall, adjusting its height requires disassembly and reinstallation, which is inconvenient. Therefore, to solve this problem, an easily adjustable COB cinema screen is proposed. Utility Model Content

A lead screw 5 is rotatably mounted on the horizontal surface of the L-shaped plate 1. An internal threaded block 10 is threaded onto the lead screw 5. An mounting plate 12 is mounted on the side of the internal threaded block 10. An mounting plate 8 is mounted on the side of the mounting plate 12 away from the internal threaded block 10. The COB cinema screen body 9 is mounted on the side of the mounting plate 8 away from the mounting plate 12. A first sliding rod 6 is mounted on the horizontal surface of the L-shaped plate 1. A top plate 7 is mounted on the top of the first sliding rod 6. A first sliding sleeve 11 is slidably sleeved on the first sliding rod 6.

[0024] As a technical optimization of this utility model, a motor 3 is installed on the horizontal surface of the L-shaped plate 1. The output shaft of the motor 3 is connected to the lead screw 5. A bearing 19 is installed at the bottom of the top plate 7. The top of the lead screw 5 is installed in the inner ring of the bearing 19. The output shaft of the motor 3 can easily drive the lead screw 5 to rotate, and the bearing 19 can provide guidance for the rotation of the lead screw 5.

[0025] As a technical optimization of this utility model, an installation groove 2 is provided on the horizontal surface of the L-shaped plate 1, and the motor 3 is installed in the installation groove 2. Several installation holes 4 are provided on the vertical surface of the L-shaped plate 1. The installation holes 4 can facilitate the fixing of the L-shaped plate 1, thereby facilitating the installation and fixing of the L-shaped plate 1 on the wall, and completing the installation of the COB cinema screen body 9.

[0026] As a technical optimization of this utility model, a reinforcing plate 13 is installed on the side of the mounting plate 12. The side of the reinforcing plate 13 away from the internal thread block 10 is connected to the mounting plate 8. The reinforcing plate 13 can increase the connection strength between the mounting plate 8 and the mounting plate 12.

[0027] As a technical optimization of this utility model, a second sliding rod 16 is installed on the horizontal surface of the L-shaped plate 1, and a second sliding sleeve 17 is slidably sleeved on the second sliding rod 16. A fixing piece 18 is installed on the outer wall of the second sliding sleeve 17, and the fixing piece 18 is connected to the mounting plate 8. Through the cooperation of the second sliding sleeve 17 and the second sliding rod 16, a guide can be provided for the COB cinema screen body 9 when it moves up and down, thereby improving the stability of the COB cinema screen body 9 when it moves up and down.

[0028] As a technical optimization of this utility model, a mounting block 15 is installed at the top of the second slide bar 16, and a connecting rod 14 is installed on the side of the mounting block 15.

[0031] When the height of the COB cinema screen body 9 needs to be adjusted, the motor 3 is started. The output shaft of the motor 3 drives the lead screw 5 to rotate. The rotation of the lead screw 5 causes the internal thread block 10 to move on the lead screw 5, allowing the internal thread block 10 to move up and down on the lead screw 5. The up and down movement of the internal thread block 10 causes the mounting plate 12 to move up and down, which in turn causes the mounting plate 8 and the COB cinema screen body 9 mounted on the side of the mounting plate 8 to move up and down. This allows the height of the COB cinema screen body 9 to be adjusted conveniently according to the height of the seats installed in the cinema. It can automatically complete the height adjustment of the COB cinema screen body 9.

[0032] Furthermore, utilizing the self-locking property of the lead screw 5 itself, after the motor 3 is turned off, the internal thread block 10 stops at a certain position on the lead screw 5. By utilizing the self-locking property of the lead screw 5, the position of the internal thread block 10 can be fixed, thereby fixing the position of the mounting plate 12, the mounting plate 8, and the COB cinema screen body 9 mounted on the side of the mounting plate 8. After the height adjustment of the COB cinema screen body 9 is completed, the position of the COB cinema screen body 9 can be fixed, making the height adjustment of the COB cinema screen body 9 convenient and quick.
