[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1: This example provides a flip fixture for LED display production, see Figure 1-4 Specifically, it includes a fixed block 1, the fixed block 1 is rotatably connected to a rotating drum 11, one end of the rotating drum 11 is rotatably connected to a driving block 12, the driving block 12 is internally threadedly connected to a threaded rod 13 that penetrates, one end of the threaded rod 13 extends into the interior of the rotating drum 11, and one side of the outer wall of the rotating drum 11 is fixedly connected to a pair of vertically corresponding support blocks 14, each support block 14 is slidably connected to a through clamping block 15, one end of the threaded rod 13 is hinged to horizontally symmetrical connecting rods 16 on both sides, and the inner ends of the connecting rods 16 are hinged to the corresponding clamping blocks 15 through hinges;

[0025] The adjacent end surfaces of a pair of clamping blocks 15 are fixedly connected to rubber pads 4, the lower end surface of the fixing block 1 is fixedly connected to the support rod 5, and the lower end surface of the support rod 5 is fixedly connected to the base 51. The threaded rod 13 is located at the center line position of the rotating drum 11, and the driving block 12 is located at the center position of one end surface of the rotating drum 11;

[0026] In the specific implementation process, Figure 1 and Figure 3 As shown, by first placing one side of the LED display screen between a pair of clamping blocks 15, rotating the driving block 12, the driving block 12 drives the threaded rod 13 connected with the internal thread to move toward the outside of the rotating drum 11, and drives the pair of clamping blocks 15 to approach each other under the action of the support blocks 14 on both sides of the outer wall of the rotating drum 11. When one side of the pair of rubber pads 4 fits against the outer wall of the LED display screen, stop rotating the driving block 12. The base 51 and the support rod 5 have a good stabilizing effect on the fixed block 1, and the rubber pad 4 has a good buffering effect, which is convenient for protecting the LED display screen. By first placing both sides of the LED display screen on the lower clamping blocks 15, rotating the driving block 12, the driving block 12 drives the threaded rod 13 and the connecting rod 16 to rotate, so that the two ends of the pair of clamping blocks 15 fit against the outer wall of the LED display screen, so that when the pair of clamping blocks 15 complete the clamping work, they also have a self-locking function, with fewer steps and higher installation efficiency.

[0027] Example 2: In Example 1, there are still problems. Therefore, based on Example 1, this example further includes:

[0028] In the specific implementation process, Figure 2 and Figure 4 As shown, the other end face of the rotating drum 11 is fixedly connected to the knob 2, the other side of the outer wall of the rotating drum 11 is fixedly connected to the ratchet 21, one side of the fixed block 1 is provided with a sliding groove 3, the interior of the sliding groove 3 is slidably connected to a slider 31, one end of the slider 31 is fixedly connected to a spring 33, the other end of the spring 33 is fixedly connected to one side of the interior of the corresponding sliding groove 3, and one end of the slider 31 is fixedly connected to a pawl 32;

[0029] The ratchet 21 is located at the center line of the drum 11, the knob 2 is located at the center line of the drum 11, the slider 31 fits in the inside of the chute 3, the slider 31 is T-shaped, and one end of the pawl 32 is locked with the outer wall of the ratchet 21;

[0030] By turning the rotating knob 2, the knob 2 drives a pair of clamping blocks 15 to rotate through the rotating drum 11 and the supporting block 14. During the rotation of the rotating drum 11, the pawl 32 and the ratchet 21 have a limiting effect on the rotating drum 11, so that the rotating drum 11 can only rotate in one direction, which is convenient for later operation. Under the thrust of the spring 33, the pawl 32 continuously engages with the ratchet 21. When the rotation of the knob 2 stops, the pawl 32 immediately engages with the outer wall of the ratchet 21 under the thrust of the spring 33, completing the self-locking function, realizing the self-locking function at any time during the rotation of the LED display, making it easy to adjust more angles to meet different working angle requirements.

[0031] Specifically, the working principle and operation method of the utility model are as follows:

[0032] Step 1: First, place one side of the LED display screen between a pair of clamping blocks 15, rotate the driving block 12, and the driving block 12 drives the threaded rod 13 connected to the internal thread to move toward the outside of the rotating drum 11. During the movement, one end of the threaded rod 13 drives a pair of connecting rods 16 to rotate, and under the action of the support blocks 14 on both sides of the outer wall of the rotating drum 11, the pair of clamping blocks 15 are driven to move closer to each other. The ends of the pair of clamping blocks 15 that are close to each other simultaneously drive the corresponding rubber pads 4 to move toward the outer wall of the LED display screen. When one side of the pair of rubber pads 4 is in contact with the outer wall of the LED display screen, stop rotating the driving block 12;

[0033] Step 2: Turn the knob 2. The knob 2 drives a pair of clamping blocks 15 to rotate through the rotating drum 11 and the supporting block 14, thereby adjusting the angle of the LED display screen. During the rotation of the rotating drum 11, the pawl 32 is continuously pushed away when it engages with the outer wall of the ratchet 21. Under the thrust of the spring 33, the pawl 32 continuously engages with the ratchet 21. When the knob 2 stops rotating, the pawl 32 immediately engages with the outer wall of the ratchet 21 under the thrust of the spring 33, completing the self-locking function.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
