Description

Technical Field

[0001] This application relates to the technical field of inflation connectors, and more specifically, to a dual-purpose inflation connector. Background Art

[0002] A valve stem, also known as a valve, is an independent valve body device. When opened, it allows gas to enter the space of a tubeless tire or an inner tube, and then automatically closes and seals to preserve the gas and generate air pressure to prevent the gas from escaping from the tire or inner tube. Except for solid tires, other tires or inner tubes that need to be inflated must use this device for inflation.

[0003] According to different structures, valve stems can be divided into American valve stems, French valve stems, and British valve stems. American valve stems and French valve stems are more common on bicycles. When inflating different valve stems, it is necessary to replace the corresponding inflation connector, which is very inconvenient to use. Utility Model Content

Therefore, the above terms should not be understood as limitations on the present utility model.

[0020] Such as Figure 1 - Figure 2As shown, the structure of the dual-purpose inflatable joint according to an embodiment of the present application is illustrated. Among them, the dual-purpose inflatable joint includes a joint body 1, a first nozzle connection end 2, and a second nozzle connection end 3. The joint body 1 includes an air inlet channel 11, a first installation channel 12, and a second installation channel 13 that are in communication with each other. One end of the air inlet channel 11 is connected to an inflation source. The first installation channel 12 and the second installation channel 13 are arranged coaxially opposite to each other. The first nozzle connection end 2 includes a first inflation channel 21. The first nozzle connection end 2 is arranged at one end of the first installation channel 12 so that the first inflation channel 21 is in communication with the first installation channel 12. The second nozzle connection end 3 includes a second inflation channel 31. The second nozzle connection end 3 is arranged at one end of the second installation channel 13 so that the second inflation channel 31 is in communication with the second installation channel 13. That is to say, after the air inlet channel 11 is connected to the inflation source, the gas filled by the inflation source can flow through the first installation channel 12 and the second installation channel 13 respectively from the air inlet channel 11, and finally flow out from the first inflation channel 21 and the second inflation channel 31. Preferably, the joint body 1 is of a T-shaped structure, and the first nozzle connection end 2 and the second nozzle connection end 3 are arranged at both ends of the joint body 1 coaxially opposite to each other.

[0021] Specifically, the switching valve assembly 4 includes a first stop member 41, a second stop member 42, and an elastic telescopic member 43. The elastic telescopic member 43 is arranged between the first stop member 41 and the second stop member 42 and is in a compressed state. The first stop member 41 is arranged in the first installation channel 12 to isolate the air inlet channel 11 and the first inflation channel 21. The second stop member 42 is arranged in the second installation channel 13 to isolate the air inlet channel 11 and the second inflation channel 31.

[0022] More specifically, the first stop member 41 includes a first base 411 and a first ejector rod 412. The first base 411 is arranged in the first installation channel 12 and isolates the first inflation channel 21 under the elastic force of the elastic telescopic member 43. The first ejector rod 412 extends from the first base 411 into the first inflation channel 21. The second stop member 42 includes a second base 421 and a second ejector rod 422. The second base 421 is arranged in the second installation channel 13 and isolates the second inflation channel 31 under the elastic force of the elastic telescopic member 43. The second ejector rod 422 extends from the second base 421 into the second inflation channel 31.

[0023] In particular, a hollow first spacer 5 is provided between the first nozzle connection end 2 and the first base 411. The inner diameter of the first spacer 5 is smaller than the outer diameter of the first base 411. A hollow second spacer 6 is provided between the second nozzle connection end 3 and the second base 421. The inner diameter of the second spacer 6 is smaller than the outer diameter of the second base 421. It should be understood that the elastic telescopic member 43 is always in a compressed state to press the first stopper 41 and the second stopper 42. In the natural state, the first base 411 is abutted against the first spacer 5 to isolate the first inflation channel 21. Similarly, the second base 421 is abutted against the second spacer 6 to isolate the second inflation channel 31. When the first nozzle connection end 2 is connected to the nozzle, the first ejector rod 412 is pressed by the nozzle, the elastic telescopic member 43 is compressed, and the first base 411 is separated from the first spacer 5, so that the intake channel 11 is connected to the first inflation channel 21 to inflate the nozzle. At this time, under the action of the greater elastic force provided after the elastic telescopic member 43 is compressed, the second base 421 fits more closely with the second spacer 6 to prevent gas from leaking out of the second inflation channel 31, and vice versa.

[0024] Preferably, the first nozzle connection end 2 is detachably connected to the first installation channel 12, and the second nozzle connection end 3 is detachably connected to the second installation channel 13. In the example of the present application, the detachable connection method is a threaded connection, and other known connection methods can also be set, which are not limited by the present application. And in the example of the present application, the first nozzle connection end 2 is a French nozzle connection end, and the second nozzle connection end 3 is an American nozzle connection end.

[0025] The basic principles of the present application have been described above in conjunction with specific embodiments. However, it should be noted that the advantages, advantages, effects, etc. mentioned in the present application are only examples and not limitations. It cannot be considered that these advantages, advantages, effects, etc. are essential for each embodiment of the present application. In addition, the above-disclosed specific details are only for the purposes of illustration and easy understanding, rather than limitations. The above details do not limit the present application to necessarily adopt the above specific details to implement.
