Description

Compatible with air pump connectors for different air nozzles Technical Field

[0001] This work primarily reveals an air pump connector, especially an air pump connector that can be used with different nozzles. Prior Technology

[0002] Please refer to the patent application No. I592595 of my country, "Rotary Air Nozzle", which is a rotary air nozzle composed of an air nozzle head, a rotary wheel, an air nozzle, an injector and a lever. The nozzle head and the rotating wheel have a reference surface and a back surface that abut against each other, and are provided with first and second pivots that are coupled to each other. The nozzle head is further recessed on the reference surface to provide a main hole for the injector to slide into, and this main hole is also connected to an air inlet. The rotating wheel is provided with a number of nozzle holes of different specifications at intervals. These nozzle holes are provided to provide matching nozzle installation, so that the rotating wheel can rotate around the first pivot and the nozzle holes and nozzles can selectively connect to the main hole. As for the lever, it is installed on the nozzle head to drive the end edge of the injector to extend into the corresponding nozzle hole and press the nozzle therein. At this time, the injector is in the position of connecting the air inlet and the nozzle. However, when the lever releases the injector, the nozzle can push the injector back to its original position, thereby cutting off the connection state of the air inlet and the nozzle.

[0003] However, although the above-mentioned air nozzles can selectively supply air to French and American connectors, the rotary wheel must be rotated to select the outlet for air before supplying air, which makes the operation complicated.

[0004] In view of the shortcomings of the above-mentioned conventional structures, the inventor has designed an air pump connector that can be used with different air nozzles, which can overcome all the shortcomings of the above-mentioned conventional structures. Summary of the Invention

[0024] The headstock 20 includes a pin 28 that is inserted into the housing 22 through the housing 22 and the lever 27, and the lever 27 is rotatable relative to the housing 22 with the pin 28 as the center.

[0025] The core 31 includes a core rod 311, a first airtight component 312, and a second airtight component 313. The core rod 311 is movably disposed within the American-style socket 201 along the axial direction parallel to the American-style socket 201. The first airtight component 312 and the second airtight component 313 are respectively sleeved on the outer periphery of the core rod 311. When the core 31 is in the American-style position, the first airtight component 312 abuts against the first airtight portion 207, and the second airtight component 313 disengages from the second airtight portion 208. When the core 31 is in the French-style position, the first airtight component 312 disengages from the first airtight portion 207, and the second airtight component 313 abuts against the second airtight portion 208.

[0026] The outer periphery of the mandrel 311 is provided with a first narrow section 314, a second narrow section 315, and a wide section 316.

[0027] The switching module 30 includes an elastic member 32, which is disposed in the American socket 201 and located on the side of the top rod 311 opposite to the American interface 205. One end of the elastic member 32 abuts against the sliding member 23 and the other end abuts against the top rod 311. The elastic member 32 can push the top rod 31 to move towards the American position.

[0028] The air pump connector 10, through the aforementioned structure, is compatible with both American and French valves. When using the air pump connector 10, an American valve (AV) can be inserted into the American socket 201 via the American interface 205, or a French valve (FV) can be inserted into the French socket 202 via the French interface 206. Then, the lever 27 is turned to the raised position, pushing the sliding member 23 to the tightened position. The compressed and deformed first airtight ring 24 and second airtight ring 25 can then tightly adhere to the American valve (AV) or the French valve (FV) and form a tight seal. When the object being filled is an American-style air valve AV, the American-style air valve AV can push the top core 31 to move to the American-style position, and the airflow from the air inlet 204 can pass through the second airtight part 208 and be output from the American-style interface 205. When the object being filled is a French-style air valve FV, the elastic member 32 can push the top core 31 to move to the French-style position, and the airflow from the air inlet 204 can pass through the first airtight part 207 and be output from the French-style interface 206. The air pump connector 10 is compatible not only with American (AV) and French (FV) air valves, but also with Clik Valve, a new type of air valve system proposed as an alternative to the traditional French air valve. The Clik Valve is inserted into the French socket 202 through the French interface 206, and the lever 27 is turned to the raised position. This not only directs airflow into the French socket 202, but the abutment 21 also pushes against the Clik Valve's valve core to counteract its pressure.
