DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0019] like Figure 1-3As shown, a flexible LED display screen includes a mounting frame 6, and a pair of upper limit rods 3 and lower limit rods 4 are respectively provided at the upper and lower ends of the mounting frame 6, which are rotatably connected to the external frame 2 of the LED display screen 1. The mounting frame 6 is provided with an radian adjustment structure, and the radian adjustment structure is respectively rotatably connected to the upper limit rod 3 and the lower limit rod 4. The mounting frame 6 is also provided with a supporting structure that cooperates with the radian adjustment structure, and the supporting structure includes a curved wheel 9 that is against the middle of the LED display screen 1 and whose movement trajectory is opposite to the arc deviation direction at both ends of the LED display screen 1.

[0020] When the present invention is in use, the mounting bracket 6 can be used to support and install the LED display screen 1. When the curvature of the LED display screen 1 needs to be adjusted according to different installation environments, the curvature adjustment structure is controlled to work, and the upper limit rod 3 and the lower limit rod 4 at both ends of the mounting bracket 6 are displaced and deflected, thereby driving the two ends of the LED display screen 1 to bend, thereby realizing the adjustment of the curvature of the LED display screen 1. At the same time, the supporting structure works, and the cambered wheel 9 is against the middle part of the LED display screen 1 and tends to move in the opposite direction of the bending of the LED display screen 1. The cambered wheel 9 is used to support the middle part of the LED display screen 1, and cooperates with the upper limit rod 3 and the lower limit rod 4 at both ends to ensure the stability of the curvature adjustment of the LED display screen 1.

[0021] The radian adjustment structure also includes a first sliding block 7 and a second sliding block 18 respectively provided at both ends of the mounting frame 6, and the upper and lower ends of the first sliding block 7 and the second sliding block 18 are rotatably connected to the upper limit rod 3 and the lower limit rod 4 respectively. One end of the mounting frame 6 is provided with a second bracket 5, and the two ends of the second bracket 5 are fixedly connected to the first sliding block 7 and the second sliding block 18 respectively. A worm 11 is rotatably connected to the mounting frame 6, and the worm 11 is engaged with a worm gear 12. The worm gear 12 is fixedly connected to a rotating rod 13 rotatably connected to the mounting frame 6, and the lower end of the rotating rod 13 is fixedly connected to a spur gear 14. One end of the spur gear 14 is engaged with a second sliding rack 15, and the second sliding rack 15 is fixedly provided on the second bracket 5.

[0022] like Figure 1-3 As shown, a rotating handle 10 is provided at one end of the worm 11, which drives the worm 11 to rotate through the rotating handle 10, and the worm 11 drives the worm gear 12 to rotate, and the worm gear 12 drives the rotating rod 13 to rotate, and the rotating rod 13 drives the spur gear 14 to rotate. During the rotation of the spur gear 14, it engages with the second sliding rack 15, thereby driving the second sliding rack 15 to slide under the limit of the mounting bracket 6, and the second sliding rack 15 drives the second bracket 5 to slide, and the second bracket 5 drives the first sliding block 7 and the second sliding block 18 at both ends to slide respectively, and the first sliding block 7 and the second sliding block 18 respectively drive the upper limit rod 3 and the lower limit rod 4 to deflect, and the upper limit rod 3 and the lower limit rod 4 are used to provide driving force to the two ends of the LED display screen 1 to achieve the curvature adjustment of the LED display screen 1.

[0023] The support structure further includes a first sliding rack 16 meshing with the spur gear. The first sliding rack 16 is fixedly connected to the first bracket 8 , and the first bracket 8 is provided with the cambered wheel 9 .

[0024] like Figure 3 As shown, since the first sliding rack 16 and the second sliding rack 15 are respectively arranged at the two ends of the spur gear 14, the spur gear 14 can also drive the first sliding rack 16 to slide in the opposite direction of the second sliding rack 15 when it rotates. The first sliding rack 16 drives the first bracket 8 to slide, and the first bracket 8 drives the cambered wheel 9 to press against the middle of the LED display screen 1, cooperating with the bending of the two ends of the LED display screen 1 to provide more stable support.

[0025] One end of each of the first sliding rack 16 and the second sliding rack 15 is provided with a sliding pin 17 that is slidably connected to the inner wall of the mounting bracket 6 .

[0026] like Figure 3 As shown, the sliding pin 17 plays a role in limiting the sliding of the first sliding rack 16 and the second sliding rack 15.

[0027] The LED display screen 1 is a flexible display screen, and the peripheral frame 2 is made of carbon fiber.

[0028] like Figure 1 As shown, the LED display screen 1 adopts a flexible display screen, and the peripheral frame 2 is made of carbon fiber material, which can ensure that the LED display screen 1 can adjust the curvature normally.

[0029] The working process of the present invention is as follows: when the present invention is in use, the mounting bracket 6 can be used to support and install the LED display screen 1. When the curvature of the LED display screen 1 needs to be adjusted according to different installation environments, the rotating handle 10 drives the worm 11 to rotate, the worm 11 drives the worm gear 12 to rotate, the worm gear 12 drives the rotating rod 13 to rotate, and the rotating rod 13 drives the spur gear 14 to rotate. During the rotation of the spur gear 14, it engages with the second sliding rack 15, thereby driving the second sliding rack 15 to slide under the limit of the mounting bracket 6, and the second sliding rack 15 drives the second bracket 5 to slide, and the second bracket 5 respectively drives the first sliding block 7 and the second sliding block 18 at both ends to slide, and the first sliding block 7 and the second sliding block 18 respectively drive the upper limit rod 3 and the lower limit rod 4 to deflect, and the upper limit rod 3 and the lower limit rod 4 are used to provide driving force to the two ends of the LED display screen 1 to achieve the curvature adjustment of the LED display screen 1.

[0030] At the same time, since the first sliding rack 16 and the second sliding rack 15 are respectively arranged at the two ends of the spur gear 14, the spur gear 14 can also drive the first sliding rack 16 to slide in the opposite direction of the second sliding rack 15 when it rotates. The first sliding rack 16 drives the first bracket 8 to slide, and the first bracket 8 drives the curved wheel 9 to press against the middle of the LED display screen 1, cooperating with the bending of the two ends of the LED display screen 1 to provide more stable support.

[0031] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
