The application discloses an LED display module and an radian adjusting mechanism thereof, which comprise part of technical characteristics or all the technical characteristics of the following embodiments; that is, the LED display module and the arc adjusting mechanism thereof include the following partial structures or all structures. In one embodiment of the application, an arc adjusting mechanism of an LED display module comprises a limiting pin, a fixed seat, a force application piece, a locking switch, a guide piece, a mechanism main body and a fixed seat rotating shaft: the guide piece is arranged on the mechanism main body in a sliding way to form an adjusting structure, and two ends of the adjusting structure are respectively connected with the fixed seat in a rotating way through the fixed seat rotating shaft; the force application piece, the locking switch and the limiting pin are arranged on the mechanism main body, and the limiting pin is abutted against the guide piece so as to limit the sliding state of the guide piece on the mechanism main body; the locking switch is connected with the force application part and used for loosening the force application part so as to enable the force application part to be in a locking state or a movable state; the force application piece is connected with the limiting pin and is used for separating the limiting pin from the guide piece in an active state and a stressed state so that the guide piece is in a slidable state relative to the mechanism main body. According to the radian adjusting mechanism of the LED display module, the guide piece is in sliding fit with the mechanism main body, so that the angle between the LED display modules fixed on the fixing seat is easy to adjust, on one hand, the integrated realization of small-angle adjustment and large-angle adjustment is facilitated, and smooth seamless splicing of adjacent LED display modules is realized, so that a relatively large splicing radian is formed, and the spacing requirement of a small-point spacing display product is met; on the other hand, the angle of the adjacent LED display modules can be adjusted conveniently, and therefore the curved-surface LED display screen can be installed quickly on site.

The LED display module and the arc adjusting mechanism thereof will be described in detail with reference to fig. 1 to 11.

In one embodiment, as shown in fig. 1 and 3, an arc adjustment mechanism 600 of an LED display module includes a limiting pin 610, a fixing base 620, a force application member 630, a locking switch 640, a guide member 650, a mechanism main body 660 and a fixing base rotating shaft 670; one fixing base 620 is used for fixing one, two, three or four LED modules of the LED display module or fixing positions of the LED modules, or one fixing base 620 is used for fixing one, two, three or four LED display units of the LED modules. The guide 650 is slidably disposed on the mechanism main body 660 to form an adjusting structure 690, and two ends of the adjusting structure 690 are respectively rotatably connected to the fixing base 620 through the fixing base rotating shaft 670; that is, one end of the adjusting structure 690 is rotatably connected to one of the fixing bases 620 through one of the fixing base rotating shafts 670, and the other end is rotatably connected to the other fixing base 620 through the other fixing base rotating shaft 670; connected to both ends of the adjustment structure 690 are different holders 620. In such a structural design, when the guide 650 slides on the mechanism main body 660, the length of the adjusting structure 690 is changed, and the length of the LED module or the LED display unit thereof is kept unchanged, so that the included angle between the adjacent LED modules or the LED display units thereof is changed, so that the overall radian of the LED display module is changed, and the radian adjustment of the LED display module is realized. In a specific application, the fixing base 620 may be directly connected to the LED module, or may be indirectly connected to the LED module through a middleware, further, the LED module is fixed on a box frame of the LED display module, and the box frame is separately disposed and fixed with the fixing base 620, so that the separated box frame is connected through the radian adjusting mechanism 600, and thus, by adjusting the length of the adjusting structure 690, the included angle of the adjacent LED module or the LED display unit thereof can be adjusted, thereby realizing the radian adjustment of the display curved surface of the LED display module.

The force application member 630, the locking switch 640 and the limit pin 610 are all disposed on the mechanism main body 660, and the limit pin 610 abuts against the guide member 650 to limit the slidable state of the guide member 650 on the mechanism main body 660.

The force application member 630 may drive the limit pin 610 in a stressed state, and limit the sliding state of the guide member 650 on the mechanism main body 660 by the limit pin 610; in this embodiment, when the force application member 630 is forced to drive the limiting pin 610, the guide member 650 is in a slidable state on the mechanism main body 660; when the force application member 630 is not stressed, the limiting pin 610 abuts against the guide member 650, so that the guide member 650 is in a non-slidable state on the mechanism main body 660.

Further, due to the structural design, the angle between the LED display modules or the display units thereof fixed on the fixing base 620 is easy to adjust, the radian of the LED display modules can be adjusted at a small angle, and the radian of the LED display modules can be adjusted at a large angle, so that the rapid control of the small angle adjustment and the large angle adjustment is realized integrally, the smooth seamless splicing of the adjacent LED display modules is facilitated, the relatively large splicing radian is formed, and the spacing requirement of the small-point spacing display product is met.

In one embodiment, as shown in fig. 3, the fixing base 620 is provided with a first rotating shaft hole 621, the guide 650 is provided with a second rotating shaft hole 652 at a first mounting end 651 thereof, and one fixing base rotating shaft 670 passes through the first rotating shaft hole 621 and the second rotating shaft hole 652, so that the first mounting end 651 is rotatably connected with one fixing base 620 through one fixing base rotating shaft 670.
