Problems solved by technology

The traditional connection device is usually fixed by bolts, that is, tap the threaded holes on the parts to be connected, screw the bolts into the threaded holes when installing, and screw out the bolts in the opposite direction when disassembling. The loading and unloading process takes a certain amount of time, especially in large-scale construction. very time consuming
[0003] In addition, the current LED display unit is a box structure manufactured by a full sheet metal process. The process is complicated, and the accuracy of the shape and size is difficult to guarantee. Moreover, the accumulated work difference of each unit directly affects the surface flatness and overall installation of the LED display. Alignment of Seams Between Units Straight
It has a great impact on the effect of LED display

Abstract

The invention discloses a connecting device comprising a base plate and a fixing element fixing a part to be connected on the base plate, wherein the fixing element comprises a shaft and a spring fixed on the shaft; one end of the shaft is provided with a non-round end button, and the other end of the shaft is provided with a limit part; the spring is arranged between the non-round end button and the limit part; the part to be connected and the base plate are both provided with button holes; and the button holes are adaptive to the non-round end button and the shaft can rotate in the button holes. The assembling and disassembling process of the connecting device only includes two movements: pressing and rotating. The connecting device is easy in operation and greatly improves the efficiency of site operation compared with traditional thread tigthening.

Description

technical field [0001] The invention relates to the field of installation, in particular to a connecting device for fixedly connecting two or more LED display screen units. Background technique [0002] Existing LED display screens are usually assembled from multiple LED display units. The traditional connection device is usually fixed by bolts, that is, tap the threaded holes on the parts to be connected, screw the bolts into the threaded holes when installing, and screw out the bolts in the opposite direction when disassembling. The loading and unloading process takes a certain amount of time, especially in large-scale construction. Very time consuming. [0003] In addition, the current LED display unit is a box structure manufactured by a full sheet metal process. The process is complicated, and the accuracy of the shape and size is difficult to guarantee. Moreover, the accumulated work difference of each unit directly affects the surface flatness and overall installatio...
