DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 , the utility model provides a technical solution:

[0024] A LCD display screen with adjustable viewing angle comprises a display screen main body 1, a left mounting plate 2 and a right mounting plate 3 are respectively fixedly mounted on both sides of the back of the display screen main body 1, the outer side of the left mounting plate 2 is rotationally matched with one end of a first connecting member 4, the other end of the first connecting member 4 is rotationally matched with a fixing rod 5, and the outer side of the right mounting plate 3 is rotationally matched with one end of a second connecting member 6. By arranging the left mounting plate 2 and the right mounting plate 3, it is convenient to fix the display screen main body 1 and to connect the display screen main body 1 with the first adjustment structure and the second adjustment structure.

[0025] The first adjusting structure also includes a first adjusting structure for adjusting the left and right angles of the display screen body 1. The first adjusting structure includes a first screw rod 7. The first screw rod 7 is slidably matched with the mounting seat 8. A first rotating seat 9 is fixedly mounted on one end of the first screw rod 7. The first rotating seat 9 is rotatably matched with the other end of the second connecting member 6. The first adjusting structure also includes a first handle 11. One side of the first handle 11 is rotatably matched with the mounting seat 8. The center of the first handle 11 is threadedly matched with the first screw rod 7. By setting the first handle 11 and the first screw rod 7 for use, one side of the display screen body 1 can be pushed to rotate around the other side, thereby realizing the adjustment of the left and right viewing angles of the display screen body 1. Improve the viewing effect; a limiting ring 12 is set on one side of the first handle 11, and a limiting groove 13 is set inside the mounting seat 8. The limiting ring 12 and the limiting groove 13 are slidably matched. By setting the limiting ring 12 and the limiting groove 13 for use, the first handle 11 and the mounting seat 8 can be rotated and matched, and at the same time, the first handle 11 is prevented from being separated from the mounting seat 8, so that the first screw 7 can push and pull one side of the display screen body 1 normally; the fixing rod 5 is fixedly installed on one end of the top of the support frame 10, and the mounting seat 8 and the other end of the top of the support frame 10 are integrally formed. By setting the support frame 10, the display screen body 1 can be supported.

[0026] It also includes a second adjustment structure for adjusting the pitch angle of the display screen main body 1, the second adjustment structure includes a second screw 14, the second screw 14 is slidably matched with the second connecting member 6 and the through hole opened between the right mounting plate 3, one end of the second screw 14 is threadedly connected to a nut 15 fixedly installed on the inner side of the right mounting plate 3, and the other end of the second screw 14 is fixedly installed with a second handle 16. By setting the second adjustment structure, it is convenient for users to adjust the pitch angle of the display screen main body 1, thereby further improving the viewing effect.

[0027] When in use, the device is moved to a designated position. When the viewing angle of the display screen body 1 needs to be adjusted, the first handle 11 is rotated to make the first handle 11 start to rotate on one side of the mounting seat 8. The first handle 11 drives the first screw rod 7 to rotate. The rotating first screw rod 7 slides in the mounting seat 8, so that the first rotating seat 9 approaches or moves away from the mounting seat 8, and at the same time pushes the second connecting member 6 and the right mounting plate 3 to approach or move away from the mounting seat 8, so that one side of the display screen body 1 starts to rotate around the first connecting member 4 on the other side, so as to adjust the left and right angles of the display screen body 1. The second handle 16 is rotated forward, and the second handle 16 drives the second screw rod 14 to rotate, so that the second connecting member 6 and the right mounting plate 3 are released from each other, and the pitch angle of the display screen body 1 is rotated. After the adjustment is completed, the second handle 16 is rotated in the reverse direction to drive the second screw rod 14 to rotate, so that the second connecting member 6 and the right mounting plate 3 are pressed against each other, and the pitch angle of the display screen body 1 is locked, that is, the adjustment of the viewing angle of the display screen body 1 is completed.
