[0002] With the continuous improvement of technology and people's quality of life, air conditioners are widely used. The air duct is also equipped with insulation layer, fan, diverter, air guide plate and other components to deliver the cold and hot air of the air conditioner into the room through the duct opening. An openable and closable duct cover is provided at the duct opening to control the opening, direction and range of the air supply. The air duct cover in the prior art generally includes a guide member, a connecting member and a wind shield. After the guide member and the wind shield are connected by the connecting member, the wind shield is installed corresponding to the air duct outlet, and the driving mechanism and the guide member cooperate to drive the displacement of the wind shield relative to the air duct opening. In order to avoid the burning of the insulation layer in a high temperature environment, a flame retardant layer is also provided in the air duct shell and the wind shield member to improve the safety of the operation of the air duct and its internal components. Its main defects are: the connecting member and the wind shield are connected by multiple screws, which is inconvenient to operate when the wind shield needs to be disassembled to clean and maintain the wind shield and the internal components of the air duct. It is also easy to fail to tighten during assembly due to the slipping of the screws or the loss of the screws during disassembly, affecting the convenience of use; secondly, the cooperation between the connecting member and the wind shield lacks positioning, and the connecting member and the guide member lack positioning when connected by multiple screws, resulting in a long connection alignment time and poor assembly accuracy and efficiency.
