A modular fan splicing
structure based on a sliding live buckle, comprising a plurality of fan units, each of the fan units has a buckle piece with a slidable live buckle on one side wall and a clamping groove matched with the live buckle on the other side wall, and two adjacent fan units are spliced and fixed by inserting the live buckle on one of the fan units into the clamping groove on the other fan unit, and the side surfaces of the buckle piece and the clamping groove are provided with first and second
electrical connection terminals, through the above technical solution, the slidable live buckle and the matched clamping groove are integrated on both sides of the fan, the zero-tool disassembly and
assembly of "alignment and locking, pulling and separation" between the fans is realized, the
electrical connection is simultaneously completed at the moment of splicing through the integrated
electrical connection terminals on the same side, the independent wiring requirement is eliminated, the modular infinite expansion architecture is constructed, and the rapid networking and maintenance of any number of fans are supported.
