Description

Inflatable device and its gas nozzle connector

This creation mainly discloses an air nozzle connector of an inflatable device, and in particular relates to an air nozzle connector suitable for an American mouth and a French mouth.

The valve is a self-contained valve body device that allows air to enter the tire when it is opened, and then automatically closes and seals the air to generate air pressure to prevent the air from escaping the tire. At present, the common valves are divided into two types according to different structures: American valve (Schrader valve) and French valve (Presta valve). American mouth is the most widely used valve, common in vehicles such as automobiles, motorcycles, and bicycles. French mouths are common on bicycles, especially road bikes. Due to the different outer diameters and structures of the two kinds of valves, it is impossible to share one valve joint. Therefore, there is currently a dual-purpose air nozzle connector on the market. An American nozzle connection hole and a French nozzle connection hole are arranged side by side at one end of the gas nozzle connector, and a wrench is arranged at the other end of the gas nozzle connector. After reaching the valve joint, the wrench can be pulled to squeeze the rubber sleeve provided in the valve joint, so that the rubber sleeve can be elastically deformed to connect and hold the valve to be inflated. However, this type of dual-purpose air nozzle joint is limited by two connecting holes arranged side by side, so that the structure is more complicated, the volume is larger, and the operating space must be larger. In addition, the air nozzle is connected through the elastic deformation of the rubber sleeve, which is easy to loosen during operation.
