[0018] Next, in combination with the accompanying drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0019] A backlight rubber frame with an all-round anti-loosening structure disclosed by the present utility model is mainly applied to the scenario where when a traditional backlight rubber frame is used, after the rubber frame and the backlight are fixed, only the up and down positions can be prevented from falling off, and it is easy to fall off when it is loose in the front, back, left and right positions, and the fixation is unstable.

[0020] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, a backlight rubber frame with an all-round anti-loosening structure includes a backlight body 1 and a rubber frame body 2. The backlight body 1 is located inside the rubber frame body 2. Three fitting holes 3 are opened on the outer walls of both sides of the rubber frame body 2. A same edge convex block 4 is fixedly connected at the four peripheral edges of the fitting holes 3 close to the backlight body 1. Three fitting grooves 5 are opened on the outer walls of both sides of the backlight body 1. The edge convex block 4 is adapted to the fitting groove 5.

[0021] In the specific working process, the backlight body 1 is embedded inside the rubber frame body 2. By pressing the rubber frame body 2, the edge convex block 4 at the inner side of the fitting holes 3 on both sides of the rubber frame body 2 is limited in the fitting groove 5 of the backlight body 1. Limited by the edge convex block 4 on both sides of the backlight body 1, an interference fit is formed through the pressing force, and the fixation is more stable.

[0022] Among them, the size of the fitting hole 3 is smaller than the size of the fitting groove 5. In this way, the edge convex block 4 inside the fitting hole 3 can be limited in the fitting groove 5, and it can also cooperate with the subsequent interference fit.

[0023] Among them, an interference fit is formed between the edge convex block 4 and the fitting groove 5. In this way, by applying pressure to the rubber frame body 2, the fitting hole 3 and the fitting groove 5 are tightly combined through the edge convex block 4, so that the two are tightly connected and not easy to fall off.

[0024] Among them, the position of the adaptation slot 5 corresponds to that of the adaptation hole 3, and the edge bumps 4 are respectively used in cooperation with the adaptation slot 5 and the adaptation hole 3. In this way, the adaptation slot 5 and the adaptation hole 3 are positionally limited on both sides of the rubber frame body 2 and the backlight body 1. The edge bump 4 inside the adaptation hole 3 is limited in the adaptation slot 5, so as to stably fix the rubber frame body 2 and the backlight body 1.

[0025] Among them, the four corners of the adaptation slot 5 are all set to be rounded structures. In this way, it is more convenient to limit the edge bump 4, and the pressing process is not hindered, making it better to carry out the fixing work.

[0026] Refer to Figure 2 , in a preferred embodiment, gaskets 6 are provided on the inner walls of the four corners of the rubber frame body 2, and the gaskets 6 are used in cooperation with the backlight body 1.

[0027] Specifically, the backlight body 1 is assisted in fixing at the four corners of the rubber frame body 2, and the gasket 6 increases the friction force to limit and fix the rubber frame body 2 and the backlight body 1.

[0028] Among them, the gasket 6 is made of rubber material, and the four gaskets 6 are attached to the four corners of the backlight body 1. In this way, the rubber material of the gasket 6 can deform, and it closely fits with the four corners of the backlight body 1 and the rubber frame body 2 during the extrusion process, increasing the friction force between the two and making the fixation more stable.

[0029] Working principle: When in use, the backlight body 1 is placed inside the rubber frame body 2. The size of the adaptation hole 3 is smaller than that of the adaptation slot 5. By pressing the rubber frame body 2, the edge bump 4 inside the adaptation hole 3 is in interference fit with the adaptation slot 5, so as to limit and fix the edge bump 4 in the adaptation slot 5 of the backlight body 1. At the same time, the gaskets 6 at the four corners of the rubber frame body 2 deform and closely fit with the four corners of the backlight body 1, increasing the friction force, and further stably fixing the rubber frame body 2 and the backlight body 1.

[0030] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
