DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figure 1-Figure 6 As shown, the anti-overflow backlight panel provided in this embodiment includes a main frame 1, a mounting frame 2 is arranged inside the main frame 1, a backlight panel 3 is clamped inside the mounting frame 2, a pressing frame 4 is installed on the mounting frame 2 through a threaded rod 6, and a sealing strip 5 is arranged below the pressing frame 4;

[0025] The mounting frame 2 and the pressing frame 4 are both provided with interconnected threaded holes diagonally, and the threaded rod 6 is threadedly screwed and connected with the threaded holes. The upper end surface of the threaded rod 6 is provided with a hexagonal groove, and a handle is provided on the outer side above the threaded rod 6. The settings of the hexagonal groove and the handle provide a variety of rotation methods for the threaded rod 6. When the backlight panel 3 needs to be disassembled, the pressing frame 4 can be removed by rotating the threaded rod 6 and the threaded hole, so that the backlight panel 3 in the mounting frame 2 can be removed. When installing, first put the backlight panel 3 into the mounting frame 2, and then press the pressing frame 4. At this time, the upper and lower threaded holes are connected, and then the threaded rod 6 is used for threading and connection;

[0026] It should be noted that the height of the backlight panel 3 is flush with the height of the mounting frame 2, and the pressing frame 4 presses and seals the gap between the backlight panel 3 and the mounting frame 2, which can effectively prevent the occurrence of light spillage; the sealing strip 5 is an opaque rubber sealing strip, which can block and seal it to prevent the occurrence of light spillage;

[0027] A cover plate 7 is installed above the main frame 1. The cover plate 7 includes a cover plate frame 9 and a light-transmitting transparent plate 10. The size of the transparent plate 10 is adapted to the size of the exposed backlight plate 3, and does not affect the light transmission of the backlight plate 3, and does not cause light overflow.

[0028] Both sides of the cover plate 7 are provided with fixing pins 8 for fixing the cover plate 7 and the main frame 1; a slot is provided on the outside of the main frame 1, and the fixing pin 8 includes a sliding channel 11 adapted to the slot and an elastic pin 12 sliding in the sliding channel 11; sliding grooves are provided on both sides of the sliding channel 11 and the inside of the slot, and a compression spring 13 is provided inside the sliding groove. Limiting plates that abut against the inner end of the compression spring 13 are provided below both sides of the elastic pin 12, and a second limiting plate that abuts against the outer end of the compression spring 13 is provided at the opening of the outer end of the sliding groove. The limiting plate and the second limiting plate are both for limiting the compression spring. When the cover is removed, When installing the cover plate 7, the elastic latch 12 is pulled outward, the compression spring 13 is squeezed and contracted, and the elastic latch 12 slides in the sliding channel 11 and disengages from the slot, thereby realizing the separation of the cover plate 7 from the main frame 1. When installing, similarly, the elastic latch 12 is pulled outward, the compression spring 13 is squeezed and contracted, and the elastic latch 12 slides outward in the sliding channel 11, and then the cover plate 7 covers the main frame 1. At this time, the sliding channel 11 is connected with the slot, and then the elastic latch 12 is released, and the spring latch 12 is ejected into the slot of the main frame 1 by the rebound of the compression spring 13, thereby realizing the rapid installation of the cover plate 7;

[0029] A pull ring 16 is provided at the outer end of the elastic latch 12 , and the pull ring 16 is convenient for pulling the elastic latch 12 to realize the rapid disassembly and assembly of the cover plate 7 .

[0030] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0031] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
