The invention discloses a connecting device, an LED (light emitting diode) display unit and an LED display system, wherein the connecting device comprises a first connecting piece, a sliding positioning piece, a second connecting piece, a sway arm and a driving handle, wherein the first connecting piece comprises a first substrate provided with a first guide groove arranged through along the first direction and a first connecting through hole; the second connecting piece comprises a second substrate provided with a second guide groove arranged along the first direction and a positioning hole;the sway arm is movably arranged in the second guide groove, one end of the sway arm is provided with a second clamping part matched with a first clamping part, the second clamping part is provided with a locking position allowing a positioning pin to be inserted into a positioning hole and an unlock position allowing the positioning pin to be separated from the positioning hole; the driving handle is pivotally installed in the second substrate along a pivot axis perpendicular to the first direction, the second end of the sway arm is hinged to the hinge point on the driving handle; and the hinge point is deviated from the pivot axis of the driving handle. The connecting device provided by the invention has the characteristics of simplicity in structure and convenience in use; furthermore,the dismounting efficiency is improved effectively.
Description
technical field [0001] The invention relates to the field of assembly technology, in particular to a connection device, an LED display unit and an LED display system. Background technique [0002] In the prior art, there are many ways to connect cabinets and panels. For the connection between LED screen structures, combination methods are often used, such as: louver pins, rotary zippers, buckles, etc. . At present, the application range of display screens is getting wider and wider. Media conferences, advertisements, performances, conferences, etc. all require LED displays to provide reliable display effects. [0003] At present, the installation of the LED display screen needs to be coordinated by multiple people, and the support frame and the connecting piece at the rear of the screen body are usually fixed by connecting the bolts with the display screen box. Regardless of whether the support frame at the rear of the screen is made of aluminum profiles, square steel, or ...
