[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] An LED display screen curved cabinet includes a mounting frame 1, a handle 2, a cover 4, and LED modules. Multiple mounting frames 1 are provided and arranged side by side. Multiple covers 4 are also provided, and the multiple covers 4 are respectively fixedly mounted on the mounting frames 1. Each joint of two mounting frames 1 is provided with an adjustable angle connection mechanism. Multiple LED modules are provided, and the multiple LED modules are fixedly mounted on the mounting frames 1.

[0022] Each mounting bracket 1 is provided with multiple spacers 11, and every two spacers 11 form an installation area for LED modules. Multiple LED modules are installed according to the spacers 11. Each LED module has a locking knob on the back, and the mounting bracket 1 is also provided with a locking block that cooperates with the locking knob to fix the LED module on the mounting bracket 1.

[0023] The connecting mechanism includes a connecting block 5, a fixing block 7, and an arc-shaped handle 6. The connecting block 5 and the fixing block 7 are respectively fixedly installed on two mounting brackets 1. The arc-shaped handle 6 is rotatably installed on the fixing block 7. A pull rod 8 is rotatably installed on the arc-shaped handle 6. A slide bar 12 that mates with the pull rod 8 is slidably installed on the connecting block 5. The end of the slide bar 12 has an arc-shaped portion, and the pull rod 8 mates with the arc-shaped portion. The arc-shaped handle 6 is also provided with a pressing block 9. The pressing block 9 cooperates with the groove at the bottom of the fixing block 7 to limit and lock the arc-shaped handle 6. When the curvature needs to be adjusted, pressing the pressing block 9 can remove the limiting effect.

[0024] One end of the connecting block 5 is arc-shaped, and the slide bar 12 is also arc-shaped. The connecting block 5 has an opening, and the slide bar 12 can slide along the connecting block 5 in an arc shape, so that the arc-shaped handle 6 can follow the slide bar 12 in an arc shape, thereby allowing the other mounting bracket 1 to rotate in an arc shape with the other mounting bracket 1.
