Description

Technical Field

The two L-shaped fixing pieces are connected together by bolts to form a stable fixing structure.

[0049] In one embodiment, for the above-mentioned moving component 6, the moving component 6 includes a cylinder 601 arranged on the inner side of the screen module connection box 1, a circular mounting platform 602 is arranged on the top of the cylinder 601, a positioning shaft 603 is arranged on the top of the circular mounting platform 602 passing through the screen module connection box 1 (in addition, in specific applications, the positioning shaft 603 is respectively fixedly connected to the circular mounting platform 602 and the screen module connection box 1), a driving gear 604 is sleeved on the outer side of the positioning shaft 603 (in addition, in specific applications, the driving gear 604 is movably connected to the positioning shaft 603), moving racks 605 are symmetrically arranged on both sides of the driving gear 604 (in addition, in specific applications, the driving gear 604 and the moving rack 605 are meshed with each other), and the two ends of the moving rack 605 are symmetrically arranged A U-shaped movable block 606 is fixedly connected to the L-shaped connecting arm 2, and limit blocks 607 are symmetrically arranged on both sides of the bottom end of the U-shaped movable block 606 (in addition, in specific applications, the limit block 607 is movably connected to the limit shaft 608), one end of the limit block 607 is provided with a limit shaft 608 connected to the screen module connection box 1 (in addition, in specific applications, the limit shaft 608 is fixedly connected to the screen module connection box 1), and the output end of the cylinder 601 is provided with a connecting block 609 (in addition, in specific applications, the top of the connecting block 609 is fixedly connected to the U-shaped movable block 606 located at one end of the driving gear 604), thereby providing horizontal movement capability of the LED screen body 4, ensuring that the screen can flexibly adjust its position according to the needs of the competition or activity, so as to better display the athlete information.

[0050] In addition, it should be noted that the U-shaped moving block 606 includes a first U-shaped moving block and a second U-shaped moving block symmetrically arranged at both ends of the driving gear 604, a moving rack located on one side of the driving gear 604 passes through the first U-shaped moving block and is fixedly connected to one end of the second U-shaped moving block, and a moving rack located on the other side of the driving gear 604 passes through the second U-shaped moving block and is fixedly connected to one end of the first U-shaped moving block.
