Description

Valve joint structure suitable for two types of nozzles

The invention relates to a gas nozzle joint for inflating, and in particular to a gas nozzle joint structure that can be used for both American and French specifications.

According to the current tires, there are two types of American and French gas nozzles, and the American and French gas nozzles each have their corresponding inflation joints, so you must buy both American and French inflation joints. To cope with the use, there are problems of inconvenience in use and waste of money.

Therefore, the inventor of this case previously created Bulletin No. I498479 "American and French dual-use nozzle joint structure". Although this nozzle joint is applicable to both American-style and French-style nozzles, there is no need to change the structure or complicated operations. However, when the gas nozzle joint is inflated with the American gas nozzle, it is necessary to use a screw lock method to connect the internal screw teeth of the American gas nozzle socket of the gas nozzle connector with the external screw teeth of the American gas nozzle, so that the The valve can only be inflated before it can be opened. In addition to the inconvenience and time consuming, the American and French gas nozzles are connected in different ways, which may cause confusion when the user operates.

In order to improve the above-mentioned shortcomings, there is a method such as bulletin I544147 "Dual-use quick connector structure", which is provided with a French chuck to hold a French air nozzle and an American chuck to hold an American air valve. Eliminates the time consuming of the valve connector screw lock American valve It is more convenient to use. However, when the dual-purpose quick connector is used with the American-style air nozzle, the positioning operation ring is rotated first, so that the positioning operation ring presses against the thimble positioning member, and the thimble positioning member enters the thimble positioning groove to fix the thimble. The American-style gas nozzle can be put into the dual-use quick connector for connection operation, so it still consumes time and inconvenience, and it needs to rotate the positioning operation ring when used with the American-style gas nozzle, resulting in two types of American-style and French-style. The connection operation of this type of gas nozzle is different, which cannot allow ordinary users to operate intuitively, and it is easy to confuse users, which is not conducive to market promotion.

In view of the above-mentioned conventional gas nozzle joint structure, the present inventor has the disadvantages of inconvenient use of operation and easy confusion to the user, etc., based on the ideas of Nasi and creation, he has studied and tried samples in various ways, and After several corrections and improvements, the present invention finally came out.

The invention provides a nozzle joint structure applicable to two types of nozzles, including: a connector body, one end of the connector body is provided with an American-style nozzle socket and a French-style nozzle socket having an outer diameter smaller than the American-style nozzle socket. And the French nozzle socket is a distance inward from the American nozzle socket, and the French nozzle socket is provided with a movable slot inward, and the other end of the joint body is provided with an air inlet hole. The edge is provided with at least one American chuck through hole penetrating from outside to the American gas nozzle jack, at least one French chuck through hole penetrating from outside to the French gas valve jack, and at least one external penetrating to the French gas hole The through hole of the push-in positioning block of the mouth socket is provided with an air-tight ring between the American-style nozzle socket and the French-style nozzle socket; at least one American-style chuck is provided in the American-style chuck through-hole, and the American-style chuck is displaced For the stroke displacement of entering or leaving the American-style nozzle socket, and one end of the American-style chuck corresponding to the direction of the American-style nozzle socket is provided with an American-style clamping end with matching teeth, and a first limiting end is provided on the outside of the American-style chuck; At least one French chuck, provided on the French chuck Hole, and the French crosshead displacement stroke displacement is entering or leaving the French gas nozzle receptacle, and one end of the cartridge should French French gas nozzle A French-shaped clamping end with a matching tooth is provided in the direction of the insertion hole, and a second limiting end is provided on the outside of the French chuck; at least one thrust positioning block is disposed in the thrust positioning block through hole, and the displacement of the thrust positioning block is A stroke displacement when entering or leaving the French gas nozzle jack, and one end of the thrust positioning block is provided with a thrust positioning end corresponding to the direction of the French gas nozzle jack, and a third limiting end is provided outside the thrust positioning block; a control group Is provided on the joint body, the control group controls the first limiting end of the American chuck, the second limiting end of the French chuck and the third limiting end of the pushing positioning block; and a movable rod, Controllable displacement in the French gas nozzle jack and the movable groove of the joint body, the movable lever is provided with a positioning groove and a pressing end corresponding to the direction of the American gas nozzle jack, and the movable lever can pass gas, and The movable lever can be pushed and positioned in the direction of the American-style gas nozzle jack by the pushing and positioning block.
