The invention relates to an LED (Light-Emitting Diode) screen display unit connecting device which comprises a rotary positioning mechanism and a stretching locking mechanism. The rotary positioning mechanism comprises a base, a rotating plate, a connecting rod and a positioning pin for limiting a rotating angle of the rotating plate; the base is connected with the rotating plate by a rotating pin; 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 draw hook, an eccentric shaft and a knob; a mounting part is arranged below the draw hook; a shaft hole is arranged in the rotating plate; and after the eccentric shaft passes through the shaft hole, the draw hook is arranged on the eccentric shaft by a push mounting pin, the knob is arranged on the rotating shaft and the knob is rotated to further drive the draw hook to move up and down so as to implement locking. According to the device disclosed by the invention, LED unit box bodies can be conveniently connected and combined together, are firstly positioned and then are locked; external tools are not required for connecting the LED unit box bodies; the assembling efficiency is greatly improved; and the flatness and the uniformity of an assembled integral display screen can be effectively ensured.
Description
technical field [0001] The invention relates to a device connection device, in particular to a connection device for a novel LED display screen. Background technique [0002] Usually, a large-scale LED display screen is composed of splicing LED unit boxes. The connection and locking method between individual LED unit boxes has a great impact on the flatness and uniformity of the entire display screen. The current mainstream connection The method is bolt connection, which is not compact enough, and external tools must be used for connection, so the working efficiency is relatively low. Contents of the invention [0003] In order to solve the above problems, the present invention provides a connection device for an LED display screen with a positioning and locking function. [0004] The technical solution of the present invention is as follows: a connection device for LED screen display unit, including a rotation positioning mechanism and a tension locking mechanism, the ro...
