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.

[0025] The utility model provides Figure 1-5 A backlight module wire fixing device shown in the figure includes a backlight module 1, an input end of the backlight module 1 is electrically connected to a wire 2, and a positioning component 4 for fixing the position of the wire 2 is arranged on one side of the backlight module 1; the positioning component 4 includes a fixing plate 401 sleeved on one end of the wire 2, a limiting plate 402 for limiting the movement of the fixing plate 401 is arranged on the front of the fixing plate 401, a fixing frame 3 is fixedly connected to the front of the backlight module 1, a limiting component 5 for fixing and releasing the limiting plate 402 is arranged inside the fixing frame 3, a receiving groove 403 is opened at the top of the limiting plate 402, the wire 2 is inserted and connected inside the receiving groove 403, and the horizontal longitudinal section of the receiving groove 403 is set to be semicircular.

[0026] It should be noted that the backlight module 1 and the wire 2 are backlight modules of model MJ0001; the fixed frame 3 is a cube with a square groove in the middle, and the height of the fixed plate 401 is matched with the height of the square groove in the middle of the fixed frame 3, so that when the fixed plate 401 penetrates into the interior of the fixed frame 3, the fixed plate 401 cannot rotate inside the fixed frame 3, so that the moving direction of the fixed plate 401 is the direction of the square hole in the middle of the fixed frame 3. Two limiting plates 402 are provided, and storage grooves 403 are provided on the opposite sides of the two limiting plates 402. When in use, The two limiting plates 402 are sleeved on the outer wall of the wire 2 through the storage groove 403, and the position of the limiting plate 402 is fixed by the limiting component 5. One side of the limiting plate 402 is fixed by the fixing frame 3 and the limiting component 5. When the wire 2 is pulled toward the side away from the backlight module 1, the wire 2 will drive the fixing plate 401 to move. When the fixing plate 401 moves to fit with one side of the limiting plate 402, the movement of the fixing plate 401 is limited by the limiting plate 402 at the fixed position, thereby limiting the movement of the wire 2 by the fixing plate 401 that cannot move.

[0027] Specifically, the limiting component 5 includes a slot 501 opened on one side of the limiting plate 402, and a square threaded tube 502 for limiting the movement of the limiting plate 402 is clamped inside the slot 501. A moving component 7 for moving the square threaded tube 502 is provided on one side of the square threaded tube 502. Blocking blocks 503 are symmetrically provided on both sides of the limiting plate 402, and a cavity 6 is opened on one side of one of the blocking blocks 503, and the square threaded tube 502 is inserted and connected inside the cavity 6.

[0028] It should be noted that there are two blocking blocks 503, both of which are fixedly connected to the inside of the fixed frame 3, and the distance between the two blocking blocks 503 is adapted to the width of the fixed plate 401 and the limiting plate 402, so that the fixed plate 401 and the limiting plate 402 can penetrate into the space formed by the two blocking blocks 503 and the fixed frame 3, and the two sides of the fixed plate 401 are respectively fitted with the two blocking blocks 503, the top and bottom ends of the fixed plate 401 are respectively fitted with the inner walls of the top and bottom ends of the fixed frame 3, and the two sides of the two limiting plates 402 are respectively fitted with the two blocking blocks 503, the top of one limiting plate 402 is fitted with the inner wall of the top end of the fixed frame 3, and the other limiting plate 402 is fitted with the inner wall of the bottom end of the fixed frame 3, and the blocking blocks 503 is not fixed to the limiting plate 402 and the fixed plate 401, and the fixed frame 3 is not fixed to the limiting plate 402 and the fixed plate 401; the shape of the set square threaded tube 502 is a cube with a threaded hole in the middle, and the opened cavity 6 is adapted to the set square threaded tube 502, so that the square threaded tube 502 cannot rotate inside the cavity 6. When the positions of the two limiting plates 402 need to be fixed inside the fixed frame 3, the two limiting plates 402 are first moved to the inside of the fixed frame 3, and the square threaded tube 502 is moved to the inside of the card slot 501 through the moving component 7. The limiting plate 402 cannot be moved due to the restriction of the square threaded tube 502, thereby completing the fixing of the position of the limiting plate 402.

[0029] Specifically, the moving component 7 includes a threaded rod 701 threadedly inserted and connected to one side of the square threaded cylinder 502, a rotating member for rotating the threaded rod 701 is provided on one side of the fixed frame 3, and the rotating member includes a rotating block 702 arranged on one side of the fixed frame 3, and a hexagonal hole 703 for rotating the rotating block 702 is opened on one side of the rotating block 702, the threaded rod 701 is inserted and connected to the inner wall of one side of the cavity 6, the threaded rod 701 is inserted and connected to the inner wall of one side of the fixed frame 3, and the threaded rod 701 is fixedly connected to the other side of the rotating block 702, and a limiting block 8 is sleeved on the middle part of the threaded rod 701, and the limiting block 8 is inserted and connected inside the cavity 6, and the horizontal longitudinal section of the limiting block 8 is set to a circular ring shape.

[0030] It should be noted that one end of the threaded rod 701 is fixedly connected to a rotating block 702, wherein a limiting block 8 is fixedly sleeved in the middle, and the limiting block 8 is fitted with the inner wall of one side of the cavity 6 but not fixed, and the rotating block 702 is fitted with one side of the fixed frame 3 but not fixed. When in use, the threaded rod 701 cannot be moved due to the restrictions of the limiting block 8 and the rotating block 702; a hexagonal hole 703 compatible with a hexagonal wrench is provided on one side of the rotating block 702. When it is necessary to rotate and move the square threaded tube 502, a hexagonal wrench is inserted into the hexagonal hole 703, and the rotating block 702 is driven to rotate by the hexagonal wrench, and the threaded rod 701 is driven to rotate by the rotating block 702. The threaded rod 701 drives the square threaded tube 502, which is threadedly connected to it but cannot rotate, to move by rotating.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
