Description

Valve adapter structure for French valves

The invention relates to an air nozzle joint for connecting the inflation nozzle of vehicle tires, and the tire is inflated by the air nozzle joint, especially for the design of high pressure, fast combination and easy detachment of the French air nozzle.

The inflation of vehicle tires is to install an inflation nozzle designed with a check valve on the tire, and then use a pressurized pump to inflate it, and the end of the pressurized pump is provided with an air nozzle joint, and the air nozzle joint is used to connect the inflation nozzle. Combining conduction, at present, all the gas nozzle connectors are combined with the gas nozzle, and the fixing device on the gas nozzle connector needs to be switched to open before the gas nozzle connector can be combined with the gas nozzle, and then the fixing device is locked to make the gas nozzle connector stable. Bite the inflator mouth, then let go and inflate smoothly.

There are mainly three types of above-mentioned fixing devices:

One is the pulling tightening method, which uses the rubber in the compressed air nozzle joint to tighten the inflation nozzle. It is very convenient to use without matching the screw teeth on the inflation nozzle, but the simple rubber tightening The strength is poor, and it will fall off when inflated with high pressure.

The other is the thread rotation method. This thread rotation method uses the rotation of the female thread in the air nozzle joint to rotate the male thread of the air nozzle to make the air nozzle joint screw the air nozzle. Although it can be used for high pressure Inflated, but the process of using the auger is very slow and inconvenient.

The other is the sleeve control slider method, the inner side of the slider is provided with teeth that can be inserted into the male thread of the inflatable nozzle, which is to grasp the sleeve and push it forward to control the movement of the teeth of the slider to get embedded. To disengage, it is also necessary to grasp the sleeve and pull it back to control the movement of the teeth of the slider to disengage from the male thread. Although it can be used for high-pressure inflation, the operation process is not smooth.

And these three kinds of ways except above-mentioned shortcoming, all must both hands operation and gas nozzle joint before and after the gas nozzle is combined, all must have an operation fixing device action, use has its inconvenient, uncomfortable and troublesome.

In order to improve the above deficiencies, the inventor has previously developed the invention patent of the US Publication No. US 10,166,825 B2 "Joint structure for an air valve". The mouth is inserted through the channel of the air outlet, and it is automatically completed, and the separation can only be done by pressing the manual part of the control. However, the structures of American-style valves and French-style valves are quite different, and this patent is only applicable to American-style valves, not French-style valves.

In view of the fact that the above-mentioned patents can only be used for American-style valves, the present inventor finally released the present invention after various discussions, sample tests, and multiple revisions and improvements based on his ideas and creations.

The present invention provides an air nozzle joint structure for a French air nozzle. The air nozzle joint includes: a joint seat, an imaginary axis is arranged in the center of the joint seat, an air inlet hole is arranged at one end of the imaginary axis, and the other end of the imaginary axis An air outlet is provided, and a French-style air nozzle stop ring is arranged inside the air outlet, and a passage is provided between the air inlet and the air outlet, and there is a fastening position in the passage, and a joint groove is provided on the joint seat from the outside to the inside , the combination groove is equipped with a gas-stopping means, and the combination groove is provided with at least one control groove on the outside of the channel, and the control groove is provided with the air inlet in the direction of the air hole. In the clamping position, the control slot is provided with a pivot shaft near the air stop ring of the French valve towards the air outlet; at least one control part is respectively arranged in the at least one control slot, and one end of the control part is provided with a coupling shaft It is assembled on the pivot shaft so that the control part can swing in an arc shape with the combined shaft. The other end of the control part extends and is respectively provided with an engaging part and a controlled part in sequence. The ends of the engaging part are teeth The shape can protrude from the clamping position; at least one return part, the return part is arranged on the control part, so that the occlusal part of the control part is normally pushed into the clamping position; an airtight cover, the airtight The cover is arranged outside the combination groove of the combination seat, and cooperates with the air-stopping means to create an airtight space in the combination groove; and a control means is arranged at the center of the combination seat relative to the direction of the air inlet hole. The means is set in the channel of the airtight space and is linked with the controlled part, and the control means extends to the outside of the joint seat and can be manually switched. When the control means is manually switched, the controlled part will be displaced. Make the occlusal part of the control part leave the clamping position abnormally; the air nozzle joint is used for a French air nozzle, and the French air nozzle is provided with an air inlet part, a screw thread part and a neck in sequence. The French-style air nozzle is inserted through the air outlet, the neck is tightened by the French-style air-stop ring to stop the air, the thread part is engaged by the occlusal part at the clamping position, and the thread part can only be locked by the outlet The air hole advances in one direction toward the air inlet hole.

The main purpose of this invention for the valve joint structure of the French valve is to use the valve joint to inflate the French valve, or the bite action of the valve joint to separate from the French valve after the inflation is completed, all can be completed with one hand. In addition, the combination only needs to insert the French air nozzle through the air outlet hole of the air nozzle joint to complete automatically; the separation only needs to drive the control part to actuate through the control means, which has the advantages of simple operation and convenience.

The second purpose of the present invention is for the nozzle joint structure of the French nozzle. If the inflation pressure is too high during the inflation process, when the French nozzle is pushed outward by the air pressure, the force of the push will simultaneously push the control valve to the outside. The occlusal part of the workpiece is pulled towards the screw teeth of the French air nozzle, so that the occlusal part bites the screw teeth of the French air nozzle with greater force, so that the French air nozzle does not fall off easily, and is more suitable for high-pressure inflation.
