[0020] like Figure 1-6As shown, a quick-connect structure of a tent air pump includes a pump body 1, an air outlet 11 is arranged on one end face of the pump body 1, a flexible joint structure 2 is arranged at the air outlet 11, and the flexible joint structure 2 includes a connecting member 21, an inner rotating member 22 and an outer rotating sleeve 23.

[0021] One end of the connecting member 21 is fixedly connected to the pump body air outlet 11 , and an air outlet hole 211 is provided inside the connecting member 21 to communicate with the air outlet 11 .

[0022] The inner hole of the inner rotating member 22 is a three-hole section structure, which are an upper hole section 221, a middle hole section 222 and a lower hole section 223, and the inner diameters of the three increase in sequence from top to bottom. The upper hole section 221 is provided with an internal thread to form an internal thread connection port for connecting with the inflation nozzle of the inflatable tent. The middle hole section 222 is provided with at least one upper annular protrusion 2221. This figure only illustrates the structure of one, and in practice it can be set to two or more as needed. The upper annular protrusion 2221 is movably connected to the upper annular groove 212 on the outer wall of the connecting member 21. The lower hole section 223 is provided with at least one lower annular protrusion 2231. This figure only illustrates the structure of one, and in practice it can be set to two or more as needed. The lower annular protrusion 2231 is movably connected to the lower annular groove 12 on the outer wall of the upper end of the pump body 1.

[0023] By connecting the upper annular protrusion 2221 with the upper annular groove 212, the inner rotating part 22 can be axially limited relative to the connecting part 21 and can rotate freely circumferentially. At the same time, by connecting the lower annular protrusion 2231 with the lower annular groove 12, the inner rotating part 22 can be axially limited relative to the pump body 1 and can rotate freely circumferentially.

[0024] The outer wall of the inner rotating member 22 is provided with a plurality of radial strips 224 at intervals, and the outer ends of the radial strips 224 are engaged with the slots 231 on the outer rotating sleeve 23, and the engagement structure can realize the synchronous rotation of the outer rotating sleeve 23 and the inner rotating member 22. This figure only illustrates the structure of four radial strips 224, and in practice, two, three or even more radial strips can be provided as needed, and considering the force balance, the radial strips 224 are distributed at equal intervals along the circumferential direction.

[0025] In summary, the quick interface structure designed in the utility model is provided with a movable joint structure 2 on the air outlet 11 of the pump body 1, and the movable joint structure 2 is composed of a connecting part 21, an inner rotating part 22 and an outer rotating sleeve 23. During use, the rotation of the rotating sleeve 23 can drive the inner rotating part 22 to rotate, and then drive the internal threaded connection port in the hole section 221 on the inner rotating part to rotate to achieve a quick connection with the tent inflation nozzle. The whole connection process is very labor-saving and quick, and has the characteristics of simple and practical structure.

[0026] Here, considering the need for easy processing and assembly, the inner rotating member 22 is composed of a symmetrically arranged left rotating body 22a and a right rotating body 22b connected together.
