Description

Multi-purpose inflation joint

technical field

The invention relates to an inflatable joint, in particular to a multipurpose inflatable joint.

Background technique

The air nozzle of the tire and the inflation device (such as an air pump or an air pump) must be connected through an inflation joint, so that the inflation device can inject gas into the air nozzle of the tire through the inflation joint , in order to achieve the effect of inflating the tire.

There are many types of air nozzles for tires, and the common ones are American air nozzles, French air nozzles and British air nozzles. The early inflatable joints can only accept fixed types of air nozzles. For example, American-style inflatable joints can only accept American-style air nozzles, while French-style inflatable joints can only accept French-style air nozzles, and British-style inflatable joints can only accept British-style air nozzles.

However, this kind of inflatable joint that can only accept a single air nozzle type is not convenient in use and has the problem that the scope of use is too narrow. Therefore, there is currently an inflatable joint that can accept various air nozzles from a single air hole. , as shown in Figure 1 and Figure 2, but this kind of inflatable joint 1, when it is intended to undertake a British-style gas nozzle 2, because the British-style gas nozzle 2 has a nut 3 with a larger outer diameter, so When the inflatable joint 1 and the British air nozzle 2 are connected, the insertion depth is relatively shallow, and a clamper 4 must be locked on the inflatable joint 1, so that the clamper 4 can be used for the British air nozzle. 2 to clamp the nut 3 to ensure the tight connection between the British air nozzle 2 and the inflatable joint 1. However, this kind of inflatable joint 1 that must be additionally locked with the holder 4 is not only inconvenient to use, but also increases the inconvenience of carrying, and when the inflatable joint 1 is used to inflate the American or French air nozzle , the holder 4 must be disassembled from the inflatable joint 1, so there is also the problem of easy loss.

In addition, there is also an inflatable joint that can provide American, French, and British air nozzles at the same time, such as the American, British, and French general inflatable nozzle device disclosed in Taiwan Patent Certificate No. M386404, which mainly provides three sets of air holes for respectively It can be accepted by American, French and British air nozzles. However, this type of inflatable joint that provides three sets of inflatable holes is too bulky for bicycle users who must carry inflatable devices. .

In view of this, the inventor of the present invention aimed at many defects and inconveniences caused by the incomplete structural design of the above-mentioned inflatable joints, conceived deeply, and actively researched and improved the trial production to develop and design this case.

The gas is slightly released into the second flow channel 245, so that the gas diversion blocking member 25 is pushed to a second diversion position (as shown in Figure 16), so that the guide The flow blocking member 25 blocks the first flow channel 242 from the combined flow chamber 247, so that the second flow channel 245 and the combined flow chamber 247 are in a state of communication and fluid conduction. .

Then, the trigger lever 26 can be pulled from the loose position to the pressing position (as shown in FIG. 17 ), so that the pressing seat 248 of the integrated injector 24 can be pressed by the pivot joint 261 of the trigger lever 26 . Force is applied, and the pressing seat 248 is pressed against the first and second diverter seats 241, 244, and the first and second diverter seats 241, 244 are pressed against the first and second pressing seats respectively. On the rings 22, 23, the first and second tightening rings 22, 23 are elastically deformed after being stressed, so that the French valve 94 located in the first perforation 231 of the second tightening ring 23 is tightened. Clamp and form an airtight state. In this way, the gas can be output by the inflator (i.e. inflated), and then pass through the connecting pipe 90, the inflation flow channel 216 of the housing 21, the diversion channel 249 of the combined pressure injector 24, the combined and divided flow Chamber 247, the second runner 245 and the second perforation 231 of the second tightening ring 23 are injected into the French air nozzle 94 (as shown in Figure 17), so as to inflate the tire with the French air nozzle 94 Operation.

When intending to inflate an English air nozzle 95, the multipurpose inflation joint 20 of the present invention is moved to the corresponding position, and the second interface 213 of the housing 21 is provided for the British air nozzle 95 to penetrate and Pass through the second through hole 231 of the second tightening ring 23, and be adjacent to the recessed area 214 in the area around the second interface 213, and allow the nut 951 of the British air nozzle 95 to sink in, so that the The British air nozzle 95 can go deeper into the depth of the second perforation 231 of the second tightening ring 23 (as shown in FIG. 18 ).

When the British air nozzle 95 is inserted into the second perforation 231, the British air nozzle 95 will release the gas in the connected tire slightly into the second flow channel 245, so that the gas The diversion blocking member 25 is moved to the second diversion position (as shown in FIG. 18 ), so that the first flow channel 242 and the total diversion chamber 247 are separated by the flow diversion blocking member 25 The blocked state means that the second flow channel 245 and the combined flow chamber 247 are in a state of communication and fluid conduction.

Then, the trigger lever 26 can be pulled from the loose position to the pressing position (as shown in FIG. 19 ), so that the pressing seat 248 of the integrated injector 24 can be pressed by the pivot joint 261 of the trigger lever 26 . Force is applied, and the pressing seat 248 is pressed against the first and second diverter seats 241, 244, and the first and second diverter seats 241, 244 are pressed against the first and second pressing seats respectively. On the rings 22, 23, the first and second tightening rings 22, 23 are elastically deformed after being stressed, so that the British air nozzle 95 located in the first perforation 231 of the second tightening ring 23 is tightened. Clamp tightly and form an airtight state. In this way, the gas can be output by the inflator (i.e. inflated), and then pass through the connecting pipe 90, the inflation flow channel 216 of the housing 21, the diversion channel 249 of the combined pressure injector 24, the combined and divided flow Chamber 247, the second runner 245 and the second perforation 231 of the second tightening ring 23 are injected into the British air nozzle 95 (as shown in Figure 19), so as to have the tire with the British air nozzle 95 Perform inflation work.

The above-mentioned embodiments and drawings do not limit the form and style of the product of the present invention, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
