[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] Combination Figure 1 A backlight source with anti-loosening function comprises a frame 1 and a backlight source body 2, wherein a rectangular groove 14 is provided inside the frame 1, a frame cover 3 is embedded inside the rectangular groove 14, and the backlight source body 2 is embedded inside the frame cover 3

[0026] The present invention will be further described below in conjunction with the embodiments.

[0027] Example 1

[0028] See also Figure 1 , Figure 4 , Figure 5 and Figure 7 A top cover 38 is fixedly installed on the upper surface of the frame cover 3, and a penetration groove 39 is opened inside the frame cover 3 and the top cover 38. A spring 32 is fixedly installed on the lower surface of the top cover 38, and an extrusion component 33 is fixedly installed on one side of the spring 32. A rotating component 34 is hinged on the lower surface of the frame cover 3, and the backlight source body 2 is installed between the extrusion component 33 and the rotating component 34. When installing the backlight source body 2, the backlight source body 2 is pushed upward from the rotating component 34, and the spring 32 is compressed to drive the extrusion component 33 to move upward. When the backlight source body 2 completely enters the interior of the frame cover 3, the rotating component 34 is reset to its original position. At this time, the spring 32 drives the extrusion component 33 to cooperate with the rotating component 34 to firmly fix the backlight source body 2 in the frame cover 3.

[0029] The rotating assembly 34 includes a guide groove 344 opened on the inner wall of the frame cover 3, a tension spring 343 fixedly installed inside the guide groove 344, a rotating plate 341 fixedly installed on one side of the tension spring 343, and a silicone pad 342 embedded in the rotating plate 341. The rotating plate 341 is hinged to the lower surface of the frame cover 3 through the tension spring 343. The rotation plate 341 is movable by cooperating with the tension spring 343 inside the guide groove 344. The silicone pad 342 embedded in the rotating plate 341 ensures the fixation of the backlight source body 2.

[0030] The extrusion assembly 33 includes an extrusion plate 331 fixedly mounted on one side of the spring 32 and a silicone sealing pad 332 fixedly mounted on the lower surface of the extrusion plate 331 . The extrusion plate 331 can fix the backlight source body 2 in the frame cover 3 through the force of the spring 32 .

[0031] Specifically, when installing the backlight source body 2, the rotating plate 341 cooperates with the tension spring 343 to fully open due to the thrust, and the spring 32 also drives the extrusion plate 331 and the silicone sealing pad 332 to move upward to make room for storing the backlight source body 2. When the thrust disappears, the spring 32 and the tension spring 343 recover to drive the extrusion assembly 33 and the rotating assembly 34 to fix the light source body 2 inside the frame cover 3, thereby achieving the purpose of firmly fixing the backlight source body 2 inside the frame cover 3 to prevent loosening.

[0035] Specifically, after the backlight source body 2 is fixed inside the frame cover 3, when the frame cover 3 is placed into the groove 13, the slots 31 on both sides of the frame cover 3 cooperate with the buckles 12 to firmly fix the frame cover 3 inside the frame body 1, and the pressing button 363 cooperates with the compression spring 365 to allow the push block 361 to push the buckle 12 back into the groove 13 through the slot 37, thereby achieving the purpose of firmly fixing the frame cover 3 inside the frame body 1 and facilitating the removal of the frame cover 3 from the frame body 1.
