Abstract
The utility model relates to a connecting device for display units of a light-emitting diode (LED) screen. The connecting device comprises a rotary positioning mechanism and a stretching locking mechanism. The rotary positioning mechanism comprises a pedestal, a rotating plate, a connecting rod and a positioning pin for limiting a rotating angle of the rotating plate, wherein the pedestal is connected with the rotating plate through the rotating pin; and one end of the connecting rod is connected to the rotating plate, and the other end of the connecting rod is connected with the positioning pin. The stretching locking mechanism comprises a drag hook, an eccentric shaft and a knob. A mounting part is arranged below the drag hook. A shaft hole is formed in the rotating plate. After the eccentric shaft penetrates through the shaft hole, the drag hook is arranged on the eccentric shaft through a press fitting pin. The knob is arranged on a rotating shaft. The drag hook is driven to move up and down to realize locking by rotating the knob. According to the device, LED unit case bodies can be connected and combined without an external tool, and are sequentially positioned and locked, so that assembly efficiency is greatly improved, and the smoothness and uniformity of the whole assembled display screen can be effectively ensured.
