The overall idea is as follows:

A rubber pad 2 31 is fixedly installed on the side end of the fixing plate 3. The optical diffusion film body 1 is located between the rubber pad 1 28 and the rubber pad 2 31. The optical diffusion film body 1 is placed on one side of the rubber pad 1 28 in the limiting frame 2, and then the rubber pad 2 31 on one side of the fixing plate 3 is facing the optical diffusion film body 1. The fixing plate 3 is pressed toward one side of the limiting frame 2, and the fixing plate 3 on the fixing plate 3 is fixedly installed. The second rubber pad 31 is forced to squeeze the arc limit block 22, and the arc limit block 22 is forced to slide in the through hole 21. The arc limit block 22 slides and squeezes the spring 23. The spring 23 is forced to deform. The deformation of the spring 23 releases the limitation of the arc limit block 22. When the second rubber pad 31 and the fixed plate 3 pass through the arc limit block 22, the arc limit block 22 is no longer forced to reset. The arc limit block 22 resets to limit and fix the fixed plate 3. In the process of maintenance work, the limit bolt 27 is rotated, and the limit bolt 27 is forced to rotate in the threaded hole 26. The limiting bolt 27 is threadedly rotated to adjust its position, and the limiting bolt 27 is removed from the limiting hole 25 and the threaded hole 26. Then the arc-shaped limiting block 22 is pushed. The arc-shaped limiting block 22 is forced to drive the spring 23, and the spring 23 is forced to drive the limiting slider 24. When the limiting slider 24 slides out from one side of the through hole 21, the limiting slider 24 is pulled to pull the limiting slider 24, the spring 23 and the arc-shaped limiting block 22 out of the through hole 21. After the arc-shaped limiting block 22 is removed, the limit on the fixing plate 3 is released, and then the fixing plate 3 is removed, and then the optical diffusion film body 1 is removed.
[0028] The optical diffusion film body 1 includes a first diffusion layer, a second diffusion layer, a first quantum dot layer, a third diffusion layer, a second quantum dot layer and a hydrophobic dustproof layer. The first diffusion particles are arranged inside the second diffusion layer, the upper surface of the second diffusion layer is bonded to the lower surface of the first diffusion layer, the second diffusion particles are arranged inside the second diffusion layer, the first quantum dot layer is arranged below the second diffusion layer, an ultraviolet blocking layer is arranged between the second diffusion layer and the first quantum dot layer, the upper surface of the third diffusion layer is bonded to the lower surface of the first quantum dot layer, and the third diffusion particles are arranged in the third diffusion layer; the upper surface of the second quantum dot layer is bonded to the lower surface of the third diffusion layer, the hydrophobic dustproof layer is arranged on the lower surface of the second quantum dot layer, the first diffusion layer, the second diffusion layer and the third diffusion layer are all polyacrylic resin layers, the first quantum dot layer and the second quantum dot layer are both PET films with quantum dots arranged inside, and the hydrophobic dustproof layer is a nylon layer with conical holes.
[0029] Working principle:
[0030] In the first step, when the optical diffusion film structure is used, the optical diffusion film body 1 is placed on one side of the rubber pad 1 28 in the limiting frame 2, and then the rubber pad 2 31 on one side of the fixing plate 3 is facing the optical diffusion film body 1, and the fixing plate 3 is pressed toward the side of the limiting frame 2. The rubber pad 2 31 on the fixing plate 3 is forced to squeeze the arc-shaped limiting block 22, and the arc-shaped limiting block 22 is forced to slide in the through hole 21, and the arc-shaped limiting block 22 slides and squeezes the spring 23, and the spring 23 is deformed by the force, and the deformation of the spring 23 releases the arc-shaped limiting block. The positioning block 22 is limited. When the rubber pad 2 31 and the fixed plate 3 pass through the arc-shaped limiting block 22, the arc-shaped limiting block 22 is no longer reset under force. The arc-shaped limiting block 22 is reset to limit and fix the fixed plate 3. The optical diffusion film structure is designed as a fixed plate 3 that cooperates with the arc-shaped limiting block 22 to fix the optical diffusion film body 1, so that the rubber pad 1 28 and the rubber pad 2 31 squeeze and limit the optical diffusion film body 1, which effectively prevents the diffusion film from warping, thereby improving the practicability of the device.
[0031] The second step is that when the optical diffusion film structure is in use, when maintenance work is required, the limit bolt 27 is rotated, and the limit bolt 27 is forced to rotate in the threaded hole 26. The limit bolt 27 is threadedly rotated to adjust its own position, and the limit bolt 27 is removed from the limit hole 25 and the threaded hole 26, and then the arc limit block 22 is pushed. The arc limit block 22 is forced to drive the spring 23, and the spring 23 is forced to drive the limit slider 24. When the limit slider 24 slides out from one side of the through hole 21, the limit slider 24 is pulled to pull the limit slider 24, the spring 23 and the arc limit block 22 out of the through hole 21. After the arc limit block 22 is removed, the limit on the fixing plate 3 is released, and then the fixing plate 3 is removed, and then the optical diffusion film body 1 is removed. By designing the optical diffusion film structure to be quick-disassembled, quick disassembly can be achieved when the optical diffusion film is inspected and maintained, so as to improve the maintenance work efficiency, thereby effectively improving the practicality of the device.
