In order to enable the reviewing committee to have a better understanding and recognition of the features and characteristics of the present invention, the following preferred embodiments are illustrated as follows: Referring to the first to seventh figures, a preferred embodiment of the present invention is preferred. The embodiment of the present invention provides a rotary English air nozzle inflation joint 100, which mainly comprises a nozzle joint 10, a joint 20, a knob 30, a gas pipe 40, a sleeve 50 and a soft compression ring 60. Wherein, please refer to the first to third figures, one side of the nozzle connector 10 is recessed from the outside to the inside, and a limiting receptacle 11 is defined. One end of the nozzle connector 10 extends axially inwardly and has a limit The nozzle opening 11 communicates with the nozzle opening 12, and the other end of the nozzle socket 10 extends axially inwardly with a joint opening 13 communicating with the limiting pocket 11 with the edge on the opposite side of the limiting pocket 11 Two chutes 14 extending axially.

Referring to the first to third figures, the joint 20 has a joint body 21 and an inflation hole 22 extending axially through the joint body 21. The joint body 21 has a pipe joint at the outer periphery. 211, a nozzle joint 212 and a thread 313 connected between the pipe joint 211 and the nozzle joint 212, the two nozzles 212 have two sliders 214 at opposite outer positions; the joint 20 The slider 214 is slidably coupled to the sliding slot 14 of the nozzle socket 10, and is reciprocally displaced along the sliding slot 14.

Referring to the first to third figures, the knob 30 has a knob body 31 and an internal thread 32 extending axially through the knob body 31. The knob body 31 has a plurality of claws 311 protruding outwardly from one end thereof. The hook 311 is threaded through the joint opening 13 of the nozzle joint 10, and is hooked and coupled with the nozzle joint 10 in an axially rotatable manner; the internal thread 32 of the knob 30 is outside the joint 20 The thread 213 is threaded.

Referring to the first to third figures, one end of the air tube 40 is threaded through the internal thread 32 of the knob 30 and is sleeved on the tube joint 211 of the joint 20, and the other end of the air tube 40 is connected with an inflator or The air reservoir (not shown) is connected.

Referring to the first to third figures, the sleeve 50 is used to fasten the air tube 40 to the tube joint 211 of the joint 20 to prevent the air tube 40 from being loosened from the joint 20.

Referring to the first to third figures, the soft compression ring 60 is deformed by an external force and is placed in the nozzle joint 212 of the joint 20.

Therefore, the above is a description of each component of the rotary British air nozzle inflation joint 100 and its assembly manner provided by a preferred embodiment of the present invention, and then its use characteristics are as follows: When the British air nozzle 91 is inflated (as shown in the third figure), the knob 30 is first rotated in a direction of rotation, and the joint 20 is caused by the screwing of the inner and outer threads 32, 213. The chute 14 begins to move in the direction of the joint opening 13 (as shown in the fourth figure). Then, the English air nozzle 91 can be placed in the limiting pocket 11 of the nozzle joint 10, so that the inflation end 912 of the British air nozzle 91 faces the joint 20 (such as the fifth and sixth figures). The knob 30 is further rotated in the other direction of rotation to drive the joint 20 to move toward the nozzle opening 12 so that the soft compression ring 60 is located in the nozzle joint 212 of the joint 20. Pressing on the inflation end 912 of the British air nozzle 91 (as shown in the seventh figure), the gas in the inflator or the air reservoir can be poured into the British air nozzle 91 by the air tube 40. In order to achieve the effect of inflating the British air nozzle 91.

Therefore, since the structure of the present invention is simple, the cost can be greatly reduced, and the present invention can be joined to the English air nozzle by rotating the knob, so that the operation mode is quite convenient.

In addition, as shown in the eighth figure, in addition to the British gas nozzle, the limit pocket 11 of the present invention can be accommodated and joined by a US-and-two-way joint 92, so that the present invention can be directly In order to inflate the British air nozzle, the American air nozzle or the French air nozzle can be inflated by the transfer with the US-Freight joint to improve the applicability of the present invention. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All of the related art in the art will be equally changed according to the present invention. The scope of coverage.
