Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings and examples, which are only preferred embodiments of the present invention, and not all embodiments. In the description of the present invention, it is to be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are used only for convenience in describing the present invention and for simplicity in description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the present invention.

Examples

Referring to fig. 1 to 5, an automobile air conditioner air door assembly, including pivot 3 and the symmetry setting wind piece 1 in pivot 3, be provided with at 3 end fixing of pivot and dial piece 2, dial piece 2 and pivot 3 and adopt the joint structural connection, the joint structure includes that the symmetry sets up two planes 4 that are parallel to each other at 3 tip of pivot, and two planes 4 all are perpendicular with wind piece 1, are provided with draw-in groove 5 respectively on two planes 4, are provided with shaft hole 6 on dialling piece 2, are provided with block tongue 7 in the plane department in shaft hole 6, and when 3 tip of pivot and dial 2 joint cooperations, block tongue 7 just stretched into in the draw-in groove 5.

The outer side of the plane of the shaft hole 6 is provided with an inner concave part 8, the root part of the clamping tongue 7 is arranged in the inner concave part 8, when the clamping tongue 7 is not axially stressed, the inclined surface of the clamping tongue 7 is positioned in the shaft hole 6, and when the clamping tongue 7 is axially stressed, the inclined surface of the clamping tongue 7 can axially move outwards. A plurality of blind holes 9 are arranged at intervals on the end surface of the toggle piece 2. The clamping grooves 5 radially extend to the cambered surface at the end part of the rotating shaft 3, and the clamping grooves 5 on the two planes 4 extend towards opposite directions. The end part of the rotating shaft 3 is provided with a step surface 10 vertical to the plane 4, when the end part of the rotating shaft 3 is in clamping fit with the stirring piece 2, the step surface 10 is axially abutted against the stirring piece 2, and the clamping tongue 7 is axially abutted against the side wall of the clamping groove 5.
