[0020] See also Figure 1-3The utility model provides a technical solution: a light bar fixing structure of an LED display screen, comprising a mounting plate 1, two clamping plates 2, two adjusting plates 3 and a clamping mechanism 4 for adjusting the adjusting plates 3. An L-shaped fixing plate 5 is symmetrically fixedly arranged at one end of the mounting plate 1 away from the clamping plate 2, and a plurality of mounting holes 6 are provided on the L-shaped fixing plate 5. A sliding groove 7 is symmetrically arranged at one side of the mounting plate 1 away from the L-shaped fixing plate 5, and a sliding block 8 fixedly connected to the two clamping plates 2 is slidably arranged in the sliding groove 7. A return spring 9 fixedly connected to the sliding block 8 is fixedly arranged on the inner wall of one end of the two sliding grooves 7 close to each other, a control groove 12 is arranged in the inner wall of the sliding groove 7, and a control block 13 fixedly connected to the side wall of the sliding block 8 is slidably arranged in the control groove 12. A push rod groove 14 is arranged on the inner wall of the control groove 12 away from the sliding groove 7, and a push rod 15 for controlling the sliding of the control block 13 is provided in the push rod groove 14, and a knob 20 for controlling the sliding of the push rod 15 is provided at one end of the mounting plate 1 away from the clamping plate 2.

[0021] Specifically, a limit shaft 10 is fixedly provided on the inner wall of the slide groove 7, and a through hole 11 is opened on the slider 8 for the limit shaft 10 to pass through and is slidably connected to the limit shaft 10. The limit of the limit shaft 10 and the through hole 11 ensures that the slider 8 can slide stably in the slide groove 7.

[0022] Specifically, a push plate groove 23 is provided in the mounting plate 1, and one end of the push rod groove 14 away from the control groove 12 is connected to the push plate groove 23, and a push plate 16 fixedly connected to two push rods 15 is slidably provided in the push plate groove 23, and a threaded groove 17 is provided at one end of the push plate 16 away from the push rod 15, and a screw 18 is threadedly connected in the threaded groove 17, and a rotating groove 19 for the screw 18 to pass through and rotatably connected to the screw 18 is penetrated through the inner wall of the push plate groove 23 away from the push rod 15, and a knob 20 is fixedly connected to one end of the screw 18 located outside the mounting plate 1, and the screw 18 is rotated to rotate by rotating the knob 20, and the screw 18 is threadedly connected to the threaded groove 17 on the screw 18, so that the push plate 16 slides in the push plate groove 23 and drives the push rod 15 to slide in the push rod groove 14, so that the push rod 15 applies force to the control block 13 to control the sliding of the control block 13.

[0023] Specifically, the end of the control block 13 that abuts against the push rod 15 is an inclined surface, and the push rod 15 slides to the inclined surface of the control block 13. The control block 13 slides in the control groove 12 under the force, driving the slider 8 to slide in the slide groove 7 and compressing the return spring 9 so that the clamp 2 clamps the light bar. The end of the push rod 15 that abuts against the control block 13 is an arc surface, which reduces the wear between the push rod 15 and the control block 13.

[0024] Specifically, a limiting ring groove 21 is provided on the inner wall of the rotating groove 19, and a limiting ring 22 fixedly sleeved on the outer wall of the screw 18 is rotatably arranged in the limiting ring groove 21. The limiting ring groove 21 and the limiting ring 22 prevent the screw 18 from axial movement.

[0025] Specifically, the two clamping plates 2 and the two adjustment plates 3 are respectively fixed with limiting plates 24 at opposite ends, and the light bar can be better fixed by limiting the limiting plates 24 .

[0026] A specific application example of this embodiment is:

[0027] When the device is in use, the extension distance of the adjustment plate 3 is adjusted by the clamping mechanism 4 according to the width of the light bar (this is the prior art of the reference document), the light bar is placed between the two clamping plates 2 and the adjustment plate 3, the limit plate 24 is fitted with both sides of the light bar, and then the knob 20 is turned to drive the screw rod 18 to rotate, and the screw rod 18 is connected with the threaded groove 17 on the push plate 16 through the threaded connection, so that the push plate 16 slides in the push plate groove 23 and drives the push rod 15 to slide in the push rod groove 14, and the push rod 15 slides to the inclined surface of the control block 13, and the control block 13 is controlled. The control block 13 is forced to slide in the control groove 12, driving the slider 8 to slide in the slide groove 7 and compressing the return spring 9 so that the clamping plate 2 clamps the light strip to fix the light strip. The light strip is well fixed by the clamping of the clamping plate 2 and the limiting of the limiting plate 24. When removing the light strip, rotate the knob 20 counterclockwise, and the push rod 15 follows the push plate 16 to move away from the clamping plate 2. The control block 13 loses its force, and the slider 8 moves upward under the elastic force of the return spring 9, so that the clamping plate 2 releases the light strip, and the light strip can be removed.
