[0022] To further understand the content of the present utility model, the present invention will be described in detail in conjunction with the attached Figures 1-4 drawings and embodiments.

[0023] In conjunction with the attached Figures 1-4 , a dual-purpose nozzle joint in this embodiment includes a first body 1 for docking with an American nozzle and a second body 2 for docking with a French nozzle. One of the first body 1 and the second body 2 is provided with a connecting part 21, and the other is provided with an accommodating cavity 11 for accommodating the connecting part 21. A sealing ring is provided between the connecting part 21 and the side wall of the accommodating cavity 11. In this embodiment, the connecting part 21 is provided on the second body 2, and the accommodating cavity 11 is provided on the first body 1. In other implementation modes, the connecting part 21 is provided on the first body 1, and the accommodating cavity 11 is provided on the second body 2. The accommodating cavity 11 is a cylindrical accommodating groove, and the shapes of the connecting part 21 and the accommodating cavity 11 are matched so that the first body 1 and the second body 2 can rotate relative to each other.

[0024] The first body 1 and the second body 2 are connected in a manner that is radially relatively rotatable and axially relatively fixed. The first body 1 is provided with a first channel 15 for gas flow, and the second body 2 is provided with a second channel 24 for gas flow. The first channel 15 and the second channel 24 are communicated, and the bottom wall of the accommodating cavity 11 is provided with a communication hole for communicating the first channel 15 and the second channel 24.

[0025] The first body 1 and the second body 2 are connected by a connecting piece. The connecting part 21 is provided with a sliding connection groove 211. The sliding connection groove 211 surrounds the connecting part 21 for one week and is connected end to end. The inner side wall of the accommodating cavity 11 is provided with a hole groove structure. Part of the connecting piece is arranged in the hole groove structure, and part of the connecting piece is arranged in the sliding connection groove 211. In this embodiment, the hole groove structure is a hole structure 12, the connecting piece is a connecting pin 3, the hole structure 12 horizontally penetrates the first body 1 and the hole structure 12 passes through the accommodating cavity 11, the connecting pin 3 is inserted into the hole structure 12, and the middle part of the connecting pin 3 is embedded in the sliding connection groove 211. One side of the hole structure 12 penetrates the side wall of the accommodating cavity 11, and the other side of the hole structure 12 is disconnected, so that the hole structure 12 forms a circumferential groove on the inner side wall of the accommodating cavity 11. One side of the middle part of the connecting pin 3 is embedded in the circumferential groove and the other side is embedded in the sliding connection groove 211. In other implementation modes, the middle section of the hole structure 12 can be completely disconnected.

[0026] In specific applications, the hole structure 12 is parallel to the cross-section of the accommodating cavity 11. In other embodiments, the hole structure 12 is inclined with respect to the cross-section of the accommodating cavity 11. When the first body 1 and the second body 2 rotate relative to each other, the middle part of the connecting pin 3 slides in the sliding connection groove 211. At the same time, both ends of the connecting pin 3 are within the hole structure 12. The side of the middle part of the connecting pin 3 abuts against the side wall of the sliding connection groove 211, restricting the relative axial movement of the first body 1 and the second body 2.

[0027] In other embodiments, the hole and groove structure is the hole structure 12. The hole structure 12 only penetrates one side wall of the accommodating cavity 11, which is not shown in the figure. The tail of the connecting piece is a screw with an arc shape. The screw is threadedly connected to the hole structure 12, and the tail of the screw is embedded in the sliding connection groove 211. In another embodiment, the hole and groove structure is a groove structure, which is not shown in the figure. The groove structure is arranged on the inner side wall of the accommodating cavity 11. The connecting piece is a ball. One side of the ball is embedded in the sliding connection groove 211, and the other side of the ball is embedded in the groove structure.

[0028] The connecting portion 21 abuts against the bottom wall of the accommodating cavity 11. The second body 2 is provided with a convex step 25. The end of the accommodating cavity 11 abuts against the convex step 25 to enable better cooperation between the first body 1 and the second body 2. The first body 1 is provided with a first external thread 14 for connecting to the inflation pump interface on the outside, and a first internal thread 13 for connecting to an American air nozzle on the inside. The second body 2 is provided with a second external thread 23 for connecting to the inflation pump interface on the outside, and a second internal thread 22 for connecting to a French air nozzle on the inside. The first body 1 is provided with a first sealing ring at the bottom of the first external thread 14, and a second sealing ring at the bottom of the first internal thread 13. The second body 2 is provided with a third sealing ring at the bottom of the second external thread 23, and a fourth sealing ring at the top of the second internal thread 22. The first body 1 is provided with a thimble 4 for pressing the valve core of the American air nozzle inside.

[0029] When in use, if it is necessary to dock with a French air nozzle, connect the first external thread 14 of the first body 1 to the inflation pump interface, and then connect the second internal thread 22 of the second body 2 to the tire air nozzle. When connecting, the second body 2 can be rotated to make the connection between the second internal thread 22 and the air nozzle tight. If it is necessary to dock with an American air nozzle, use the dual-purpose air nozzle adapter in reverse. Connect the second external thread 23 of the second body 2 to the inflation pump interface, and then connect the first internal thread 13 of the first body 1 to the tire air nozzle. When connecting, the first body 1 can be rotated to make the connection between the first internal thread 13 and the air nozzle tight.
