Description

Gas nozzle joint with automatic gas stop structure

The invention relates to a gas nozzle joint for connecting a gas nozzle of a vehicle tire, in particular to a gas nozzle joint which can be combined with high pressure and quickly and is simply disengaged with an automatic air-stop structure.

The inflation type of the vehicle tire is used to install an inflation nozzle designed on the tire, and then use the pressure pump to inflate it, and the end of the pressure pump is provided with an air nozzle connector, which is combined with the air nozzle Turn on, at present, all the air nozzle joints are combined with the air nozzles, and it is necessary to switch the fixing device on the air valve joints to open before the air nozzle joints can be combined with the air nozzles, and then lock the fixing devices to make the air nozzle joints firmly engage. Inflatable mouth, then only let go to inflate smoothly.

At present, there are three main ways of fixing devices:

One is the pulling tightening method. This pulling tightening method uses the rubber in the compressed air nozzle connector to tighten the inflatable nozzle. It is very convenient to use the screw thread on the inflatable nozzle, but the simple rubber tightening Poor strength, it will fall off when using high pressure inflation.

The other is the screw rotation method. This screw rotation method is to use the rotation of the female screw in the air nozzle connector to rotate the male screw of the inflation nozzle to make the air nozzle connector screw the air nozzle, although it can be used for high pressure. Inflatable, but using the screw process is very slow and inconvenient.

Another way is the sleeve control slider mode, the inside of the slider is provided with male teeth that can be inserted into the inflatable nozzle. This is to grasp the sleeve and push forward to control the movement of the slider teeth to obtain the embedded card. It also needs to grab the sleeve and pull it back to control the movement of the slider teeth away from the male thread. Although it can be used for high-pressure inflation, the operation process is not smooth.

In addition to the above shortcomings, the three methods must be operated by both hands, and the air valve joint must be operated by an operation fixing device before and after combining the air nozzle, which is inconvenient, inconvenient and troublesome to use.

In order to improve the above-mentioned defects, the "air nozzle joint structure for inflation" shown in the first and second figures was created before the creation. The air nozzle joint 90 includes: a coupling seat 91, which is provided with a An air inlet end 911 and an air outlet end 912, a channel 913 is provided between the air inlet end 911 and the air outlet end 912, an abutment portion 914 is provided in the channel 913; an air stop ring 92, the air stop ring 92 is fixedly installed Within the channel 913 and does not block the space between the air inlet end 911 and the air outlet end 912 is unobstructed; a movable bite member 93, the movable bite member 93 is disposed in the outlet end 912 of the joint seat 91, and the inner side is provided with teeth 931, a linkage part 932 is provided on the outer side; a control member 94 is provided in the outlet end 912 of the coupling seat 91, a manual part 941 is provided on the outer side for manual control by pressing, and a control part 942 is provided on the inner side The toggle mode cooperates with the interlocking part 932 to interlock. When the manual part 941 is pressed, the control part 942 toggles the interlocking part 932 to move the teeth 931 outward; and at least one elastic member 95, 96 is provided at Between the coupling seat 91 and the control member 94 or the movable bite member 93, the teeth 931 of the movable bite member 93 are normally located in the channel 913, and when the manual part 941 of the control member 94 is pressed, the elastic members 95, 96 Being compressed causes the tooth 931 to move out of the channel 913.

However, although the conventional gas nozzle joint structure for inflation can improve the above-mentioned deficiency, when using the gas nozzle joint 90 to connect the inflation nozzle 100 to generate conduction for inflation, the inflation nozzle 100 needs to be quite large as shown in the fifth figure. The force of the air outlet end 912 is inserted into the channel 913, so that the teeth 931 of the movable bite 93 are pushed by the thread 100A of the inflation nozzle 100 to bounce open between the inside of the channel 913 and the outside of the channel 913 until the air stop ring One end of 92 is pressed against the deformation of the end of the inflation nozzle 100, and the check valve (not shown) in the end of the inflation nozzle 100 is pressed and opened by the pushing portion 914, and the air stop ring 92 and the inflation nozzle 100 form an airtight state , The inflation nozzle 100 is ventilated with the channel 913 and the inlet end 911 to keep the gas out of the outside, so that the inflation nozzle 100 can be smoothly inflated by the nozzle connector 90, for example, the strength of the inflation nozzle 100 inserted into the nozzle connector 90 channel 913 is not strong enough , As shown in the third and fourth figures, because the air stop ring 92 is not pressed against the end of the inflation nozzle 100 and deformed, the air stop ring 92 and the inflation nozzle 100 cannot form an airtight state, so that When the air valve connector 90 inflates the air nozzle 100, gas will leak out from the air stop ring 92 and the air nozzle 100, resulting in inability to inflate smoothly, and the air valve connector 90 and the air nozzle 100 need to be re-introduced. Combining conduction is quite troublesome.

In view of the above-mentioned shortcomings of the conventional gas nozzle joint structure for inflation, the inventor has thought of the idea and creation. After many discussions and trial sample tests, and many revisions and improvements, the present invention was finally introduced.
