Air-conditioning vent vane switching structure

Abstract

An air-conditioning vent vane switching structure includes a vane switch installed between a connecting plate and a grating panel for driving a vane to rotate. The vane switch includes a push button slidably disposed on the grating panel, and a link rod coupled to the push button. An end of the link rod is rotatably coupled to the push button, and the other end of the link rod is fixed to the connecting plate. Compared with the prior art, the structure coupled to the push button and the link rod of the connecting plate is simply plugged into the corresponding hole to assemble the switching structure easily, so as to achieve the effects of simple assembling process, high production efficiency, simplified components and low production cost. The switching structure featuring a moderate operating force, a good hand feel, a labor-saving operation can meet the air-conditioning vent market requirements.

What is claimed is: 
     
         1 . An air-conditioning vent vane switching structure, comprising a vane switch installed between a connecting plate and a grating panel for driving a vane to rotate, characterized in that the vane switch comprises a push button slidably installed on the grating panel, and a link rod coupled to the push button, and an end of the link rod is rotatably coupled to the push button, and the other end of the link rod is rotatably coupled to the connecting plate. 
     
     
         2 . The air-conditioning vent vane switching structure of  claim 1 , wherein the grating panel includes a slide hole formed thereon, and the push button includes a push plate disposed on a surface of the grating panel and a connecting portion passing through the slide hole formed on an inner side of the grating panel, and the connecting portion includes a shaft hole formed thereon, and the link rod includes a shaft installed thereon and rotatably accommodated in the shaft hole. 
     
     
         3 . The air-conditioning vent vane switching structure of  claim 2 , wherein the shaft has a groove formed thereon for separating the shaft into a first portion and a second portion, and a wedge-shaped member is disposed separately on outer sidewalls of the first portion and the second portion. 
     
     
         4 . The air-conditioning vent vane switching structure of any one of  claim 1 , wherein the connecting plate includes a connecting hole formed thereon, and the link rod includes a protruding shaft disposed thereon and rotatably coupled into the connecting hole, and the protruding shaft includes a baffle disposed thereon for blocking an inner side of the connecting plate. 
     
     
         5 . The air-conditioning vent vane switching structure of any one of  claim 2 , wherein the connecting plate includes a connecting hole formed thereon, and the link rod includes a protruding shaft disposed thereon and rotatably coupled into the connecting hole, and the protruding shaft includes a baffle disposed thereon for blocking an inner side of the connecting plate. 
     
     
         6 . The air-conditioning vent vane switching structure of any one of  claim 3 , wherein the connecting plate includes a connecting hole formed thereon, and the link rod includes a protruding shaft disposed thereon and rotatably coupled into the connecting hole, and the protruding shaft includes a baffle disposed thereon for blocking an inner side of the connecting plate.
