[0024] Embodiment 1

[0025] Refer to the attached Figure 1-6, this application provides a protective device for installing an LED screen, including a frame 1, a clamping component 2, a suction cup 3, a cushion block 4 and a support block 5. The support block 5 is installed at the bottom of the frame 1, and the cushion block 4 is connected to the front of the frame 1. There are several cushion blocks 4 for supporting the LED screen 30. By means of the multiple cushion blocks 4, the contact surface with the LED screen 30 is increased, making the LED screen 30 more stable, preventing the LED screen 30 from being scratched and damaged. The suction cup 3 is connected to the frame 1 and is used to adsorb and fix the front of the LED screen 30. The clamping component 2 is installed on both sides of the frame 1. The clamping component 2 includes a clamping block 6, and the clamping block 6 is movably connected to the frame 1. The LED screen 30 is held by the clamping block 6 from the side, further strengthening the fixation of the LED and preventing it from slipping. The LED screen 30 is provided with a sliding rail 32 and a fixing seat 31. The sliding rail 32 is fixedly connected to the LED screen 30 and then the sliding rail 32 is sleeved on the fixing seat 31 for installation. During operation, the staff first fixedly connect the fixing seat 31 to the wall surface, and then gently place the bottom of the LED screen 30 on the support block 5, push the LED screen 30 towards and against the cushion block 4. At this time, the suction cup 3 contacts the LED screen 30 and is pressed, so that the air inside the suction cup 3 is squeezed out to generate a vacuum to suck and fix the LED screen 30. Close the clamping block 6 to hold the LED screen 30 from the side for clamping and fixing. Lift the frame 1 to lift the LED screen 30 towards the fixing seat 31, and then sleeve the sliding rail 32 on the LED screen 30 into the fixing seat 31 for fixed installation. This effectively avoids problems such as the LED screen 30 being broken due to the smooth surface of the protective case of the LED screen 30 being easy to slip for manual handling, or the LED screen 30 being damaged due to uneven force when the installer holds the LED screen 30 by hand. The structure is simple and convenient to use.

[0026] Specifically, the frame 1 includes a bottom plate 7, side plates 8, an upper plate 9 and vertical plates 10. One end of the two side plates 8 is connected to the bottom plate 7, and the other end is connected to the upper plate 9 to form a rectangular frame shape. The two ends of the vertical plate 10 are respectively connected to the bottom plate 7 and the upper plate 9. The vertical plate 10 is provided with a long slot 11, and a fitting 12 is arranged in the long slot 11. The suction cup 3 is connected to the fitting 12, and the fitting 12 is installed in the long slot 11 and can change its installation position in the long slot 11. When there are some fragile positions or uneven positions on the LED screen 30 where the suction cup 3 cannot be used for adsorption, the installation position of the fitting 12 can be adjusted to adjust the adsorption point of the suction cup 3. Moreover, the vertical plate 10 can play a role in strengthening the frame 1. The structure is simple and convenient for use and maintenance.

[0027] Specifically, the clamping assembly 2 further includes a dovetail block 13. The clamping block 6 includes a threaded post 15 with a first nut 14, a silica gel pad 16, and a spring 17. The silica gel pad 16 is adhesively connected to one end of the threaded post 15 for contacting the LED screen 30. The threaded post 15 passes through the dovetail block 13 and is movable. The threaded post 15 is sleeved with the spring 17. One end of the spring 17 is fixedly connected to the dovetail block 13, and the other end is fixedly connected to the side of the threaded post 15 close to the silica gel pad 16. By loosening the first nut 14 and rotating the threaded post 15 forward / backward, the compression degree of the spring 17 is adjusted, and finally the elastic force of the spring 17 on the threaded post 15 is adjusted. The LED screen 30 is fixed by the elastic force of the spring 17, which can play a buffering and fixing role to prevent damage to the LED screen 30 caused by being clamped too tightly. The side plate 8 is provided with a dovetail groove 18 that cooperates with the dovetail block 13. The dovetail block 13 is installed in the dovetail groove 18. The side plate 8 is provided with a locking bolt 20 with a handle 19 that penetrates the dovetail groove 18. The locking bolt 20 is provided with a second nut 21. The locking bolt 20 is threadedly connected to the dovetail block 13, and when locked, the end of the locking bolt 20 abuts against the dovetail block 13 for fixation. The second nut 21 plays a role in preventing the locking bolt 20 from loosening. The position of the dovetail block 13 can be adjusted through the dovetail groove 18, and then the position of the clamping block 6 can be adjusted. When it is necessary to adjust the clamping block 6 forward or backward, loosen the second nut 21 to loosen the locking bolt 20, manually adjust the dovetail block 13 to the required position, lock the locking bolt 20 for fixation, and then lock the second nut 21 to prevent the locking bolt 20 from loosening. When installing the LED screen 30, the threaded post 15 can be pulled up first, and then released after placing the LED screen 30. At this time, the threaded post 15 rebounds and returns to its original position under the elastic force of the spring 17 to hold the LED screen 30 for fixation. The structure is simple and convenient to use.

[0028] Specifically, the material of the cushion block 4 is silica gel. The soft silica gel can play a buffering and friction - increasing role, preventing scratching on the front surface of the LED screen 30 and preventing the LED screen 30 from sliding. The side of the support block 5 in contact with the LED is provided with a silica gel layer, which can play a buffering and friction - increasing role, preventing scratching on the bottom of the LED screen 30 and preventing the LED screen 30 from sliding. The structure is simple.

[0029] Specifically, an exhaust valve 22 is provided at the tail of the fitting 12. During operation, the exhaust valve 22 is closed to keep the suction cup 3 airtight. When the work is completed, the exhaust valve 22 is opened to break the vacuum of the suction cup 3, so that the suction cup 3 is separated from the LED screen 30, avoiding damage to the LED screen 30 caused by hard - pulling the suction cup 3 to release air. The structure is simple.

[0030] Example 2

[0031] Refer to the attached Figure 1-6 The difference between this embodiment and embodiment 1 is that the vertical plate 10 is provided with a back groove 23, and the hardware 12 is provided with a third nut 24 and a fourth nut 25. The sizes of the back groove 23 and the third nut 24 are consistent, and the third nut 24 is installed in the back groove 23 and cannot rotate. The fourth nut 25 is connected to the side of the vertical plate 10 away from the back groove 23. The hardware 12 is fixed and adjusted by the third nut 24 and the fourth nut 25. When it is necessary to adjust the distance between the suction cup 3 and the LED screen 30, the fourth nut 25 is loosened, the hardware 12 is rotated forward or backward to the desired position, and the fourth nut 25 is locked to fix the hardware 12, thereby realizing the position adjustment of the suction cup 3, and the structure is simple.

[0032] Specifically, the dovetail groove 18 is provided with a transition plate 26, and the transition plate 26 is installed between the dovetail groove 18 and the dovetail block 13. When the locking bolt 20 moves forward, it presses the transition plate 26 toward the dovetail groove 18 for fixing, thereby improving the firmness and reducing the damage to the dovetail block 13 caused by the locking bolt 20 pressing against the dovetail block 13, and the structure is simple.

[0033] Specifically, the frame 1 also includes a connecting ear 27 and a reinforcing rib 28, the connecting ear 27 is connected to the side panel 8, both ends of the reinforcing rib 28 are connected to the connecting ear 27, and the reinforcing rib 28 is provided with a handle 29, which facilitates the operator to operate, improves the comfort of use, and improves efficiency.
