[0002] LCD screens are flat panel displays widely used in televisions, computers, and other devices. With their unique advantages, such as low power consumption, small size, and low radiation, they occupy an important position in modern information products. They use two polarizing materials with a liquid crystal solution sandwiched in between. When an electric current passes through the liquid, the crystal molecules rearrange themselves to control the transmission and blocking of light, thus achieving the purpose of image formation. In actual use, they are easily affected by external interference, so relevant protective measures are taken for them.

This solution addresses the convenience of using liquid crystal display screens in complex outdoor environments and meets the needs of various scenarios such as construction sites, outdoor activities, and field surveys.

[0004] However, the following problems still exist in actual use:

[0005] (1) When in use, it is placed directly, so the viewing angle cannot be changed, which reduces the viewing effect in reality and cannot adapt to different viewing needs in reality.

[0006] (2) Without a protective structure to protect it during use, the LCD screen will be damaged when it is dropped or subjected to external interference, increasing the cost of related maintenance and replacement.

[0007] Therefore, this utility model introduces a liquid crystal display screen with a protective structure. Utility Model Content

[0025] Please see Figure 4Each of the four corners of the frame 2 is equipped with a protective mechanism 9. The protective mechanism 9 includes an L-shaped protective pad 15, a T-shaped abutment block 16, a fixing screw 17, and a first reinforcing plate 18. The inner side of the L-shaped protective pad 15 abuts against the outer surface of the frame 2. The left side of the T-shaped abutment block 16 abuts against the right side of the frame 2, and the left side of the T-shaped abutment block 16 is connected to the inside of the L-shaped protective pad 15. The outer surface of the fixing screw 17 is threaded to the inside of the T-shaped abutment block 16, and the outer surface of the fixing screw 17 is threaded to the inside of the L-shaped protective pad 15 and the base 1. The front of the first reinforcing plate 18 is connected to the back of the L-shaped protective pad 15. The first reinforcing plate 18 is fixedly connected to the back of the frame 2, and the second reinforcing plate 19 is fixedly installed on the outer surface of the first reinforcing plate 18. The second reinforcing plate 19 is internally threaded with a stabilizing bolt 20, and the outer surface of the stabilizing bolt 20 is connected to the internal threads of the first reinforcing plate 18 and the frame 2.

[0027] Working principle: When changing the angle of the frame 2 and the main body 3, the fixed plate 8 can be rotated, which drives the connecting shaft 7 fixedly installed on the right side of the fixed plate 8 to rotate inside the U-shaped frame 6. Thus, when the U-shaped frame 6 rotates, it can drive the receiving block 10 and the plug rod 11 fixedly installed on the back of the receiving block 10 to rotate synchronously. After the angle of the main body 3 is rotated, the position of the plug rod 11 can be inserted into the inside of different plug slots 12 to limit the angle of the main body 3 after rotation. When limiting the position of the main body 3 after rotation again, the upper limit screw 14 can be installed inside the plug rod 11 through the inside of the through plate 13 and the inside of the base 1.

[0028] When protecting the main body 3 inside the frame 2, the L-shaped protective pad 15 can be abutted against one corner of the frame 2 first. After the L-shaped protective pad 15 is abutted, the left side of the T-shaped abutting block 16 can be abutted against the inside of the L-shaped protective pad 15 and the right side of the frame 2. Then, the inside of the T-shaped abutting block 16 can be fixed with screws 17 to ensure the protective stability of the L-shaped protective pad 15. Then, the position of the L-shaped protective pad 15 can be further stabilized by the action of the first reinforcing plate 18 and the second reinforcing plate 19. The stability bolts 20 can be installed inside the first reinforcing plate 18 and the second reinforcing plate 19 to ensure the stability during protection.
