[0054] Specifically, a marble hole 27 is provided on the second sliding portion 17, and a marble 28 is installed in the marble hole 27. When the first abutting surface 20 of the required angle of the locking block 15 slides to a position opposite to the second abutting surface 86, the marble 28 enters the arc groove 9 and generates a certain vibration, which is used to indicate that the locking block 15 moves into position to ensure that the first abutting surface 20 is opposite to the second abutting surface 86.

[0055] The working principle of the LED display screen of the embodiment of the present invention is as follows: When the curvature of the LED display screen needs to be adjusted, first slide the locking block 15 up and down so that the first abutting surface 20 of the required angle serves as the main abutting surface to face the second abutting surface 86, and then pull the first wrench 50 toward the side where the locking block 15 is located. The first wrench 50 drives the first locking member 44 to rotate, so that the first locking member 44 rotates to the first locking position, so that the abutting angle 46 is inserted into the first slot 29 on the locking block 15, thereby locking the locking block 15 in the slide slot 34.

[0056] Then the lock base 14 and the lock body 51 are locked: when the lock base 14 and the lock body 51 need to be locked, the driving portion 73 of the second locking member 68 is pressed to disengage the clamping portion 71 from the second clamping slot 62, and then the second wrench 53 is lifted to clamp the tensioning column 55 in the lock slot 19, and then the handle portion 82 of the lock shell 58 is moved in the direction close to the first fixed block 30, and finally the driving portion 73 is released, and the first torsion spring 77 drives the second locking member 68 to rotate by relying on the elastic force of the first torsion spring 77, so that the clamping portion 71 abuts against the second clamping slot 62. At this time, the lock buckle 52 is locked by relying on the pulling force between the lock shell 58 and the second fixed block 61 and the pulling force between the tensioning column 55 and the lock slot 19, so that the second abutting surface 86 abuts against the first abutting surface 20 of the required angle, thereby changing the angle between the first display screen unit 1 and the second display screen unit 4.

[0057] When unlocking is required: press the driving part 73 again to unlock the locking part 71 and the locking slot, then move the handle part 82 of the lock shell 58 in the direction away from the first fixed block 30 to release the pulling force between the lock shell 58 and the second fixed block 61, then lift the handle part 82 of the lock shell 58 and press the second wrench 53 downward at the same time to make the tensioning column 55 swing in the direction away from the lock slot 19, so that the tensioning column 55 is disengaged from the lock slot 19 to achieve unlocking.

[0058] According to the LED display screen of the embodiment of the present invention, compared with the prior art, the angle between the main abutting surface on the lock hook 18 and the mounting surface 31 on the first fixed block 30 is adjustable. When the lock buckle 52 is locked with the lock groove 19, the second abutting surface 86 of the lock body 51 abuts against the first abutting surface 20, so that the angle between the second abutting surface 86 and the mounting surface 31 also changes accordingly. Since the supporting block 10 provided with the second abutting surface 86 is connected to the second display screen unit 4, and the first fixed block 30 provided with the mounting surface 31 is connected to the first display screen unit 1, the angle between the first display screen unit 1 and the second display screen unit 4 can be adjusted, and then the curvature of the LED display screen can be adjusted, thereby improving the application range of the LED display screen.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
