Description

Air conditioner left-right pendulum wind driving crankshaft structure Technical Field The invention relates to the technical field of household appliances, in particular to a left-right swing wind driving crankshaft structure of an air conditioner. Background In air conditioner household electrical appliances field, control pendulum wind function is one of the core functions that promotes user's use comfort, and drive crankshaft as the key transmission part of pendulum wind mechanism about the air conditioner, its operational stability of structure rationality direct determination pendulum wind mechanism, assembly convenience and part commonality, drive crankshaft need accurate realization with pendulum wind connecting rod, control pendulum wind motor output shaft's transmission cooperation, need with the stable assembly of underframe control pendulum wind piece simultaneously, guarantee to keep the structure firm in the complete machine assembly flow of air conditioner (especially the pre-assembly stage before the motor installation), avoid appearing displacement or drop. The same driving crankshaft part needs to be adapted to underframe products with different types and different specifications so as to reduce the production and manufacturing cost and improve the component universalization rate, the left and right pendulum wind driving crankshaft structure of the air conditioner in the prior art has defects, and the original driving crankshaft structure has the problem of falling or difficult assembly when being adapted to a plurality of underframe products, so that the universalization of the driving crankshaft cannot be ensured. Therefore, what is needed is a left-right swing wind driven crankshaft structure of an air conditioner, which not only can solve the problem that a production feedback driven crankshaft falls off or is difficult to assemble, but also can ensure the interoperability of parts, and has the advantages of simple structure, easy assembly, stability and reliability. Disclosure of Invention (One) solving the technical problems Aiming at the defects of the prior art, the invention provides a left-right pendulum wind driven crankshaft structure of an air conditioner, which solves the problem that a driven crankshaft is not easy to fall off before a motor is installed. (II) technical scheme The left-right wind-swinging driving crankshaft structure of the air conditioner comprises a driving crankshaft and a bottom frame left-right wind-swinging block, wherein a connecting rod driving shaft is integrally formed on the upper surface of the driving crankshaft, a motor shaft sleeve is integrally formed on the lower surface of the driving crankshaft, a plurality of buckles are integrally formed on the outer surface of the motor shaft sleeve, and the buckles are arc-shaped elastic sheets protruding outwards; The free end of buckle outwards inclines to set up, and the motor axle sleeve that a plurality of buckles constitute is gapped for elastic deformation. Preferably, the inside integrated into one piece of the left and right pendulum wind piece of underframe has the underframe pilot hole, and the surface integrated into one piece of the left and right pendulum wind piece of underframe has the underframe auxiliary block, and the underframe auxiliary block is annular boss, and the end face laminating of underframe auxiliary block and driving crankshaft plays auxiliary positioning and increases the effect of mating surface leakproofness, and the biggest external diameter of buckle is slightly greater than the internal diameter of underframe pilot hole.
