The utility model relates to the technical field of conveying equipment, in particular to a modular conveyor capable of being quickly disassembled and assembled, which comprises a pair of mounting side plates, a width adjusting component arranged between the two mounting side plates, a pair of height adjusting components arranged at the bottoms of the two mounting side plates, a splice plate arranged on one side of each mounting side plate, and a plurality of connecting plates arranged on the splice plates. And a splicing groove is formed in one side, far away from the splicing plate, of each mounting side plate. The width adjusting
assembly is arranged, the rotating shaft can be driven by rotating the rotating
handle to drive the gear to rotate, then the racks on the two sides move synchronously along the guide rails, the telescopic frame is driven to accurately adjust the distance between the installation side plates on the two sides, and convenient width adjustment is achieved; and through
combined use of a mounting frame, a limiting rod, a
handle I, a disc, a spring, a limiting disc and a limiting hole, the positions of a rotating shaft, a gear, a rack and a telescopic frame after adjustment can be effectively locked, and the situation that the distance between the two mounting side plates is changed due to accidental looseness is prevented.
