[0022] Figure 1-Figure 3 The following is a schematic diagram of the entire structure of an LED backlight panel structure of the utility model. Figure 1-Figure 3 In this embodiment, an LED backlight panel structure includes a U-shaped outer panel 100, and the inner walls of the U-shaped outer panel 100 are provided with parallel and opposite customized partitions 200, and the customized partitions 200 and the U-shaped outer panel 100 are slidably engaged with each other. The two ends of the U-shaped outer panel 100 near the opening are respectively provided with limit grooves 120, and the inner bottom of the limit groove 120 is vertically extended with a pin shaft 400, and a movable shaft 400 extending to the outside of the U-shaped outer panel 100 is fixed to one side of the lower end of the pin shaft 400. The movable handle 401 is provided, and the pin shaft 400 is pushed upward by the elasticity arranged inside the U-shaped outer panel 100. The top open end of the U-shaped outer panel 100 is rotatably hinged with a top plate 300. Both ends of the top plate 300 are provided with limit blocks 310 corresponding to the limit grooves 120. When the top plate 300 rotates and abuts against the top of the U-shaped outer panel 100, the limit block 310 is embedded in the limit groove 120. After the movable handle 401 is released, the pin shaft 400 will automatically insert into the inner side of the limit block 310.

[0023] The opposite surfaces of the customized partitions 200 on both sides have vertical and side-by-side limiting slots 210, and the limiting slots 210 are through the height direction of the customized partitions 200. Here, the width of the customized partitions 200 and the limiting slots 210 is customized according to the specific thickness of the backlight film layer. When in use, multiple film layers can be directly inserted into the limiting slots 210 in sequence, without the need to use screws to install the film layers layer by layer, which is simple and efficient. Positioning grooves 110 are set on both sides of the inner wall of the U-shaped outer panel 100, and the outer side of the customized partition 200 has a slide bar 220 that matches the positioning groove 110 along its height direction. When the customized partition 200 needs to be installed, it is only necessary to take out the original customized partition 200, and then insert the new customized partition 200 into the inner side of the U-shaped outer panel 100 using the slide bar 220 and the positioning groove 110, which has good practicality.

[0024] The outer end surface of the limit block 310 has a socket 311 corresponding to the pin 400; the inner bottom of the limit groove 120 has a guide hole 130 matching the pin 400, and the lower end of the inner side of the guide hole 130 is installed with a spring 410 connected to the bottom of the pin 400 at the top. The outer side of the U-shaped outer panel 100 is also provided with a limit finger groove 140 connected to the guide hole 130, and the movable handle 401 is located on the inner side of the limit finger groove 140. When the membrane layer plate is inserted into the customized partition plate 200, the movable handles 401 on both sides and the pin 400 can be pulled down, and then the top plate can be rotated. 300, so that the limit block 310 is stuck in the limit groove 120, and then the movable handle 401 is loosened. The pin shaft 400 is quickly extended out of the guide hole 130 and inserted into the socket 311 under the action of the spring 410, so that the limit block 310 is firmly fixed in the limit groove 120, thereby realizing efficient assembly of the LED backlight panel, without the need to use cumbersome screws to tighten. Compared with the existing panel structure, the locking unit is simpler and will not occupy too much panel thickness. At the same time, it is more convenient to operate and is suitable for the installation of LED backlight panels of various sizes.

[0025] A rubber pad 500 is installed at the bottom of the top plate 300 along its length direction, and a rubber pad 500 is also installed at the bottom of the inner side of the U-shaped outer panel 100. The top plate 300 and the U-shaped outer panel 100 also have limiting grooves corresponding to the rubber pads 500, respectively. It can be understood that when the membrane layer board is inserted into the customized partition 200 and the top plate 300 box cover, the inner side of the U-shaped outer panel 100 and the bottom of the top plate 300 can form a micro-abutment against the edge of the membrane layer board through the rubber pad 500, so that the membrane layer board can be stably installed on the inner side of the panel.

[0026] In summary, in an LED backlight panel structure of the present embodiment, after the membrane layer plate is inserted into the customized partition plate 200, the movable handles 401 on both sides and the pin shaft 400 can be pulled downward, and then the top plate 300 can be rotated so that the limit block 310 is stuck in the limit groove 120, and then the movable handle 401 is released. Under the action of the spring 410, the pin shaft 400 quickly extends out of the guide hole 130 and is inserted into the socket 311, so that the limit block 310 is firmly fixed in the limit groove 120, thereby realizing efficient assembly of the LED backlight panel without the need to use cumbersome screws to tighten. Compared with the existing panel structure, its locking unit is simpler, does not occupy too much panel thickness, and is more convenient to operate.
