Arrangement for a quick positioning of a motor of a cross-flow fan

An arrangement for a quick positioning of a motor of a cross-flow fan, comprising:

• a) a housing having a left plate, a right plate and an L-shaped wind deflector between the left and right plates, the left plate having a first mounting hole, the right plate having a second mounting hole with a greater diameter, a convex ring and several securing lugs being arranged around the external rim of the second mounting hole;
• b) a cross-flow fan having a shaft at the left side thereof and positioned within the first mounting hole, a third mounting hole being axially formed at the right side of the cross-flow fan for accommodating a shock-absorbing body, the shock-absorbing body being provided with a shaft-retaining hole in the axial direction;
• and
• c) a motor apparatus having a motor body and a mounting base, the mounting base being disposed at the side facing a driving shaft of the motor body, the mounting base having a mounting member and a flange member, the mounting member being matched to the convex ring for a tight insertion into the second mounting hole, the flange member being formed around the rim of the mounting member and snugly secured to the convex ring, the external side of the flange member being provided with projecting ears corresponding to the securing lugs of the convex ring, the projecting ears being secured by screws from outside such that the motor apparatus may rapidly and precisely fit into the second mounting hole, the driving shaft being extended into the shaft-retaining hole of the shock-absorbing body of the cross-flow fan for imparting the rotary motion to the cross-flow fan.
