[0032] In this way, the first lock seat 10 is arranged on one of the two adjacent boxes 70, and the second lock seat 20 is arranged on the other of the two adjacent boxes 70. The operator drives the driving rod 41 to drive the toothed segment 31 to move through the adjusting gear 42, so that the second end of the arc plate 30 can be telescoped in the second lock seat 20 to adjust the position of the first lock seat 10 relative to the second lock seat 20. In this way, through the setting of the arc-shaped connecting lock, the angle between the first box 70 and the second box 70 can be adjusted to adjust the shape of the front surface of the LED display device. The situation that the connecting piece needs to be replaced in the related art is avoided. In addition, the angle between the first box 70 and the second box 70 can be adjusted by the meshing of the adjusting gear 42 with the toothed segment 31, which is convenient to operate and improves the efficiency during adjustment. In addition, the setting of the adjusting gear 42 on one side of the arc plate 30 facilitates the installation of the adjusting gear 42, and also facilitates the use of gears with larger diameters and tooth heights, so that the meshing of the adjusting gear 42 with the toothed segment 31 is more reliable and can withstand a larger driving force. Therefore, the technical solution of the present application effectively solves the problem of low efficiency in adjusting the shape of the front surface of the LED display device in the related art.

[0033] like Figures 1 to 5 As shown, the surface where the tooth root of the tooth-shaped segment 31 is located is an arc surface.

[0041] In this embodiment, an angle marking area is provided on the arc plate 30. By observing the angle marking corresponding to when the second end of the arc plate 30 extends into the second lock seat 20, the angle between the two adjacent boxes 70 can be known. When the positioning beads 61 are positioned and matched with the two adjacent positioning grooves 62, the angle between the two adjacent boxes 70 changes by 5°.

[0042] In this embodiment, a slide groove is provided on the first lock seat 10. The first end of the arc plate 30 is telescopically connected to the first lock seat 10, and the first end of the arc plate 30 is telescopically connected to the second lock seat 20. An elastic reset member is provided in the first lock seat 10, and the elastic reset member is located in the slide groove and connected between the first lock seat 10 and the first end of the arc plate 30. The elastic reset member applies an elastic reset force to the first end of the arc plate 30, so that the arc plate 30 can be retracted into the first lock seat 10, thereby reducing the collision of the arc plate 30 during the transportation of the box 70.

[0043] In this embodiment, fasteners 50 are also provided on the first end of the arc-shaped plate 30 and the first lock seat 10 to facilitate the fixed connection between the first end of the arc-shaped plate 30 and the first lock seat 10 .

[0044] In the present embodiment, a first abutting slope is provided on the surface of the first lock seat 10 facing the second lock seat 20, and the first abutting slope gradually moves away from the second lock seat 20 in the direction from front to back. A second abutting slope is provided on the surface of the second lock seat 20 facing the first lock seat 10, and the second abutting slope gradually moves away from the first lock seat 10 in the direction from front to back. The first abutting slope can be abutted with the second abutting slope. In this way, when the first abutting slope is abutted with the second abutting slope, the arc plate 30 retracts into the first lock seat 10 and the second lock seat 20, so that the angle between the rear surfaces of the two adjacent boxes 70 can be less than 180 degrees, so as to form an outer arc screen. In the present embodiment, the first slide runs through the first abutting slope.
