Description

Gas nozzle connector with automatic air-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 capable of high-pressure and quick coupling and simple disengagement with an automatic gas-stop structure.

The vehicle tire is inflated by using a check valve on the tire and then using a pressure pump to inflate it. The pressure pump end is provided with a gas nozzle connector, which is combined with the gas nozzle. Continuity. At present, all the gas nozzle connectors are connected to the gas nozzle. You need to switch the fixing device on the gas nozzle connector to open before you can connect the gas nozzle connector to the gas nozzle, and then lock the fixing device to make the gas nozzle connector firmly engage. Inflatable mouth, at this time you can let go smoothly.

There are three main ways of fixing devices:

One is the tightening method. The tightening method is to use the rubber in the compressed air nozzle connector to tighten the inflatable nozzle. It is very convenient to use the screw on the inflatable nozzle, but it is simple rubber tightening. The force is poor, and it will fall off when using high pressure inflation.

The other is the screw rotation method, which uses the rotation of the female screw in the nozzle joint to rotate the male screw of the inflatable nozzle to screw the nozzle joint to the nozzle, although it can be used for high pressure. Inflate, but the use of screwing is very slow and inconvenient.

Another is the sleeve control slider method. The inside of the slider is provided with male teeth that can be inserted into the inflatable mouth. This is to grab the sleeve and push it forward to control the teeth of the slider to obtain the embedded card. Disengagement also requires grasping the sleeve and then pulling it back to control the teeth of the slider to move away from the male thread. Although it can be used for high-pressure inflation, the operation process is not easy.

In addition to the above-mentioned disadvantages, the three methods must be operated by both hands, and the air nozzle joint must be operated with an operation fixing device before and after the air nozzle is combined, which is inconvenient, uncomfortable and troublesome to use.

In order to improve the above-mentioned shortcomings, the "inflatable nozzle joint structure" shown in the first and second figures was created before this creation. The nozzle joint 90 includes: a combination seat 91, which is provided with a An air inlet 911 and an air outlet 912. A channel 913 is provided between the air inlet 911 and the air outlet 912, and an abutment portion 914 is provided in the channel 913. An air stop 92 is fixed to the air stop 92. Within the passage 913 without obstructing the space between the air inlet 911 and the air outlet 912; a movable engagement member 93 is provided in the air outlet 912 of the combined seat 91, and teeth are provided on the inner side 931, a linkage part 932 is provided on the outer side; a control member 94 is provided in the air outlet end 912 of the combined 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 to When the manual operation portion 941 is pressed, the control portion 942 activates the linkage portion 932 to move the teeth 931 outward; and at least one elastic member 95, 96 is provided in Between the coupling seat 91 and the control member 94 or the movable engaging member 93, the teeth of the movable engaging member 93 The teeth 931 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 are compressed to move the teeth 931 outside the channel 913.

However, although the conventional gas nozzle joint structure for inflation can improve the above-mentioned shortcomings, when the gas nozzle joint 90 is used to connect the gas nozzle 100 to generate conduction for inflation, the gas nozzle 100 needs to be relatively 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 occlusion member 93 are pushed by the screw teeth 100A of the inflatable mouth 100 and open in a bounce manner between the inside of the channel 913 and the outside of the channel 913 until the air stop ring One end of 92 is forcedly deformed by the end of the inflation nozzle 100, and a check valve (not shown) in the end of the inflation nozzle 100 is pushed by the pushing portion 914 to open, and the air-tight ring 92 and the inflation nozzle 100 form an airtight state. The inflatable nozzle 100 is ventilated with the channel 913 and the air inlet 911 to keep the air out of the outside, and the inflatable nozzle 100 can be smoothly inflated by the nozzle joint 90. For example, the force of inserting the inflatable nozzle 100 into the nozzle joint 90 channel 913 is not strong enough. , As shown in the third and fourth figures, because the air stop ring 92 is not tightly deformed by the end of the inflation nozzle 100, the air tight ring 92 and the inflation nozzle 100 cannot form an air tight state, so that When the air nozzle connector 90 inflates the air nozzle 100, the gas will stop The pneumatic ring 92 outward leakage of the air nozzle 100, resulting in not smoothly inflated and should be repeated gas nozzle 90 and the adapter 100 in conjunction with the inflation nozzle is turned, very troublesome inconvenience.
