[0027] See also Figure 1-3 The embodiment of the utility model proposes a rotating deflated tire quick connector, which is used to connect the tire valve. When connected to the tire valve, it can be deflated by rotation without disassembly. At the same time, the tire pressure detection function of the inflation device can detect the tire pressure in real time, so that the remaining air volume of the tire can be clearly known, achieving the purpose of precise control. In order to achieve the above technical purpose, the rotating deflated tire quick connector includes a first air pipe 10 and a second air pipe 20. The specific structure is introduced as follows:

[0028] The first air pipe 10 includes an inflatable tube body 11 and a chimeric tube body 12, wherein the chimeric tube body 12 is provided with a deflation hole 121, and the inflatable tube body 11 is used to connect with an inflatable device. The inflatable tube body 11 and the chimeric tube body 12 are connected to each other. The deflation hole 121 is used for deflation and is provided on the side wall of the chimeric tube body 12. The inflatable device may be, for example, an air pump, which is not specifically limited in the present invention.

[0029] The second air pipe 20 includes a valve connection end 21 and an engagement end 22. The engagement end 22 is provided with an engagement groove 23. The second air pipe 20 is provided with a rotation groove 24 connected to the engagement groove 23. The valve connection end 21 is used to connect with a tire valve to inflate the tire. The engagement groove 23 starts from the end surface of the engagement end 22.

[0030] In the embodiment of the utility model, the bottom end of the embedded tube body 12 is embedded in the second air pipe 20 along the embedded groove 23, and the embedded tube body 12 is connected to the second air pipe 20. The inflatable tube body 11 is exposed outside the second air pipe 20, and can drive the embedded tube body 12 to rotate in the second air pipe 20 along the rotating groove 24, so that the air release hole 121 rotates to the embedded groove 23 or rotates to be close to the inner wall of the second air pipe 20.

[0031] During the insertion, the bottom end of the embedded tube body 12 is aligned with the second air tube 20, and the inflatable tube body 11 is aligned with the embedding groove 23, and embedded downwards. After the insertion is completed, the embedded tube body 12 is embedded in the second air tube 20, and the inflatable tube body 11 is exposed outside the second air tube 20. And the inflatable tube body 11 reaches the position of the rotating groove 24. The inflatable tube body 11 can drive the embedded tube body 12 to rotate in the second air tube 20 along the rotating groove 24, so that the venting hole 121 rotates to the embedding groove 23 or rotates to be close to the inner wall of the second air tube 20. When the venting hole 121 rotates to the embedding groove 23, the deflation function is realized; when the venting hole 121 rotates to be close to the inner wall of the second air tube 20, the inner wall of the second air tube 20 blocks the venting hole 121 to prevent air leakage, and normal inflation can be performed at this time.

[0032] The technical solution of the embodiment of the utility model is that the tire quick connector for rotating deflation includes a first air pipe 10 and a second air pipe 20, the first air pipe 10 includes an inflation tube body 11 and a chimeric tube body 12, the chimeric tube body 12 is provided with a deflation hole 121, the inflation tube body 11 is used to connect with the inflation device; the second air pipe 20 includes a nozzle connecting end 21 and a chimeric end 22, the chimeric end 22 is provided with a chimeric groove 23, the second air pipe 20 is provided with a rotating groove 24 connected to the chimeric groove 23, the nozzle connecting end 21 is used to connect with the tire nozzle; the bottom end of the chimeric tube body 12 is embedded in the second air pipe 2 along the chimeric groove 23 0, the chimeric tube body 12 is connected to the second air pipe 20; the inflation tube body 11 is exposed outside the second air pipe 20, and can drive the chimeric tube body 12 to rotate in the second air pipe 20 along the rotating groove 24, so that the deflation hole 121 is rotated to the chimeric groove 23 or rotated to be close to the inner wall of the second air pipe 20. It can be seen that when the deflation hole 121 is rotated to the chimeric groove 23, the deflation function can be realized without removing the connection with the tire air nozzle. At the same time, the tire pressure detection function of the inflation equipment can detect the tire pressure in real time, so that the remaining air volume of the tire can be clearly known, and the purpose of precise control is achieved.

[0033] Further, in some embodiments, such as the present embodiment, the axial direction of the embedded tube body 12 is perpendicular to the axial direction of the inflatable tube body 11. The embedded tube body 12 and the inflatable tube body 11 are in a "T" shape as a whole, and such a structural design facilitates the embedding operation.

[0034] Correspondingly, the fitting groove 23 is arranged along the axial direction of the second air pipe 20, and the rotation groove 24 is perpendicular to the fitting groove 23. The size of the fitting groove 23 matches the size of the inflatable tube body 11, and the inflatable tube body 11 can be fitted into the fitting groove 23. The rotation groove 24 is used to provide a space for the inflatable tube body 11 to rotate. After the inflatable tube body 11 is rotated, the deflation hole 121 can be exposed in the fitting groove 23, thereby achieving deflation.

[0035] Furthermore, the upper end of the chimeric tube body 12 is closed, and the lower end of the chimeric tube body 12 is open; the lower end of the chimeric tube body 12 is connected to the second air pipe 20. The upper end of the chimeric tube body 12 is closed to effectively prevent air leakage, and the lower end of the chimeric tube body 12 is open to achieve reliable communication with the second air pipe 20.

[0036] Furthermore, the outer wall of the embedded tube body 12 fits with the inner wall of the second air pipe 20 , and when the air release hole 121 rotates to be close to the inner wall of the second air pipe 20 , the inner wall of the second air pipe 20 blocks the air release hole 121 .

[0037] Specifically, the outer diameter of the embedded tube body 12 is the same as the inner diameter of the second tube body or the outer diameter of the embedded tube body 12 is slightly larger than the inner diameter of the second tube body, and the embedded tube body 12 has a certain elasticity, and the embedded tube body 12 and the second tube body are interference fit. After the two are embedded, when the vent hole 121 is located on the inner wall of the second air pipe 20, the vent hole 121 can be sealed to prevent air leakage.

[0038] Furthermore, the rotary deflation tire quick connector further comprises a rubber tube 30, which is arranged in the second air pipe 20 and is located at the lower side of the bottom end of the embedded tube body 12. When inflating, the rubber tube 30 is compressed to reduce the inner diameter of the rubber tube 30, so that the tire valve can be clamped and a reliable seal can be achieved.

[0039] Furthermore, a support platform 25 for supporting the rubber tube 30 is provided in the air nozzle connection end 21 of the second air pipe 20, and an air-inflating hole 26 is provided in the middle of the support platform 25. The width of the support platform 25 matches the width of the rubber tube 30, and the support platform 25 is annular, which can realize reliable support for the rubber tube 30. The air-inflating hole 26 is used to inflate the tire.

[0040] Furthermore, the rotating deflated tire quick connector also includes a pressing handle 40, and the pressing handle 40 includes an extrusion end 41. The extrusion end 41 of the pressing handle 40 is embedded in the second air pipe 20 along the fitting groove 23, and the extrusion end 41 is arranged on the upper side of the fitting tube body 12, and the extrusion end 41 is rotatably connected to the second air pipe 20. During the rotation of the pressing handle 40, the extrusion end 41 squeezes the fitting tube body 12, and then the fitting tube body 12 squeezes the rubber tube 30, so that the inner diameter of the rubber tube 30 becomes smaller, so that the tire air nozzle can be clamped and a reliable seal can be achieved. It can be understood that the extrusion end 41 is provided with an outwardly convex extrusion portion, and the rotation process can cause the extrusion portion to squeeze the upper end of the fitting tube body 12.

[0041] Furthermore, the tire quick connector for rotating deflation further includes a rotating shaft 50, the rotating shaft 50 passes through the second air pipe 20 and the extrusion end 41, and the extrusion end 41 is rotatably connected to the second air pipe 20 through the rotating shaft 50. It can be understood that the second air pipe 20 and the extrusion end 41 both have holes for the rotating shaft 50 to pass through.
