Description

Gas nozzle joint structure for two sizes of nozzles

The invention relates to a gas nozzle joint for inflation, in particular to a gas nozzle joint structure which can simultaneously apply both the American and French air nozzles.

According to the current nozzles of the tires, there are two types of American nozzles and French nozzles, and the American nozzles and the French nozzles have their corresponding inflation joints. Therefore, both the American and French inflatable joints must be purchased at the same time. To cope with use, there is a problem that it is not convenient to use and waste money.

Therefore, the inventor of the present case previously created Announcement No. I498479 "American-style and French dual-purpose nozzle joint structure", which is suitable for both American and French air nozzles, without the need to replace the structure or complicated operation. However, when the air nozzle joint is matched with the American air nozzle to be inflated, the screw thread is used to screw the inner screw of the nozzle of the American nozzle with the outer screw of the American air nozzle, so that the American air nozzle is The valve can be inflated before it can be inflated. In addition to inconvenient use and time consuming, the connection between the American and French air nozzles is different, which is easy to cause confusion when the user operates.

In order to improve the above-mentioned defects, there is a "dual-use quick connector structure" as disclosed in the publication No. I544147. The dual-purpose quick connector has a French chuck for holding a French air nozzle and an American chuck to hold the American air nozzle, and can Eliminate the time spent on the nozzle connector screw lock American nozzle, in use It is more convenient. However, when the dual-use quick connector is used with the American air nozzle, the positioning operation ring is first rotated, so that the positioning operation ring presses against the ejector positioning member, and the thimble positioning member enters the positioning groove of the thimble to fix the ejector pin. The American air nozzle can be placed in the dual-use quick connector for connection operation, so it is still time consuming and inconvenient to use, and the American air nozzle needs to rotate the positioning operation ring first, resulting in two types of American and French. The nozzles are different in connection operation, and cannot be operated intuitively by the general user, which is easy to cause confusion for the user and is not conducive to market promotion.

The present inventors have in view of the above-mentioned conventional nozzle joint structure, which has the disadvantages of inconvenient use and operation, and the operation action is easy to cause confusion to the user, and is based on the idea of creating and testing, and the sample test by various parties, and After many revisions and improvements, the present invention was finally introduced.
