A MULTIPLE-STAGE FRAME CONNECTING APPARATUS OF DUST COLLECTING FILTER

摘要

PURPOSE: A multiple-stage frame connection apparatus of a dust collecting filter is provided to easily and firmly connect neighboring subframes of a multiple-stage frame as the subframes are primarily connected to each other and then secondarily connected to a clamping member. CONSTITUTION: A multiple-stage frame connection apparatus of a dust collecting filter is provided to connect the multiple-stage frame, wherein a filter bag of the dust collecting filter may cover an exterior of a multiple-stage frame, in which multiple-stage of attachable and detachable subframes are connected to one another. The multiple-stage frame connection apparatus of a dust collecting filter comprises a lower end connection part that is formed at a lower end of at least one subframe of the multiple-stage subframes constituting the multiple-stage frame and includes a lower end connecting spiral wire; an upper end connection part; an upper end connection part that is formed at an upper end of at least one subframe of the multiple-stage subframes constituting the multiple-stage frame and includes an upper end connecting spiral wire, which is capable of occluding with the lower end connecting spiral wire; and a clamping member that is being connected as an end protrusion part of the lower end connecting part is inserted when neighboring subframes of the multiple-stage subframes are connected by occluding of the lower end connecting spiral wire and the upper end connecting spiral wire.
