Embodiment
Core of the present invention is to provide a kind of coupling, to reduce the probability that coupling lost efficacy because axle sleeve is separated with connected body, improves the reliability of coupling;
Another core of the present invention is to provide a kind of air conditioner.
Below, with reference to accompanying drawing, embodiment is described.In addition, the embodiment shown in below does not play any restriction effect to the summary of the invention described in claim.In addition, the solution that the full content of the formation below represented by embodiment is not limited to as the invention described in claim is necessary.
Refer to Fig. 1 and Fig. 2, the structural representation of the coupling that Fig. 1 provides for the embodiment of the present invention; The sectional view of the coupling that Fig. 2 provides for the embodiment of the present invention.
The coupling that the embodiment of the present invention provides, comprise axle sleeve 101 and connected body 102, wherein, axle sleeve 101 and the surface of contact of connected body 102 are provided with the first axial limiting portion, axle sleeve 101 and connected body 102 adopt shaft hole matching, so axle sleeve 101 refers to the inwall of axle sleeve 101 with the surface of contact of connected body 102; Accordingly, connected body 102 and the surface of contact of axle sleeve 101 refer to the outer wall of connected body 102.
Connected body 102 and the surface of contact of axle sleeve 101 are provided with the second axial limiting portion with the first axial limiting portion male-female engagement.First axial limiting portion and the second axial limiting portion adopt the mode of male-female engagement, can limit moving axially of axle sleeve 101 and connected body 102.
Connected body 102 can be used as mold insert and axle sleeve 101 is injected into integral structure, also can after axle sleeve 101 injection moulding completes, and the later stage installs, and how the present invention assembles connected body 102 and axle sleeve 101 does not limit.
