[0056] Or one end of the hollow shaft sleeve 71 passes through the second rotating body 2 and the first rotating body 1 in sequence and is detachably connected to the shaft sleeve fixing member 72, and the other end of the hollow shaft sleeve 71 abuts the second rotating body 2 to achieve the rotational connection between the first rotating body 1 and the second rotating body 2.

[0057] In some specific embodiments, Figure 8 , Fig. 9 and Fig.10 As shown, one of the first rotating body 1 and the second rotating body 2 is provided with an internal connecting member 8; the other of the first rotating body 1 and the second rotating body 2 is rotatably connected to the internal connecting member 8 to realize the rotational connection between the first rotating body 1 and the second rotating body 2.

[0058] By providing a rotating shaft 6, or an internal connecting member 8, or a hollow rotating shaft sleeve 71 and a sleeve fixing member 72, the snap fit and rotational connection between the first rotating body 1 and the second rotating body 2 can be achieved through different installation and connection methods. The user can adjust the installation method of the rotational connection between the first rotating body 1 and the second rotating body 2 according to actual needs.

[0059] In some specific embodiments, a plane formed by a central axis of the first connection portion 3 and a central axis of the second connection portion 4 is perpendicular to the central axes of the first rotating body 1 and the second rotating body 2 .

[0060] In practical applications, the extension direction of the center line connecting the first rotating body 1 and the second rotating body 2 is a preset first direction, such as Figure 1 , 2 , shown in direction A in 4.

[0061] In a specific embodiment, the thickness of the first connecting portion 3 and the second connecting portion 4 in the first direction can be consistent with the sum of the thickness of the first rotating body 1 and the second rotating body 2 in the first direction, which will make the rotating body composed of the first connecting portion 3, the second connecting portion 4 and the first rotating body 1 and the second rotating body 2 located in the same plane, and the first connecting portion 3 and the second connecting portion 4 can be selected to be parallel to each other. When the user places the rotating and folding assembly on a plane, the rotating body composed of the first connecting portion 3, the second connecting portion 4 and the first rotating body 1 and the second rotating body 2 can smoothly contact the placement surface, which also makes it easier for the user to store the rotating and folding assembly.

[0062] It should be noted that the application does not specifically limit the thickness of the first connection part 3, the second connection part 4, the first rotating body 1 and the second rotating body 2. As long as the first rotating body 1 and the second rotating body 2 can be connected to each other in a clockwise and / or counterclockwise direction, the external pipe 9 can rotate synchronously with the first rotating body 1 through the first connection part 3, or rotate synchronously with the second rotating body 2 through the second connection part 4. The thickness of the first connection part 3, the second connection part 4, the first rotating body 1 and the second rotating body 2 can be set according to actual needs. In a specific embodiment, when the thickness of the first connection part 3 and the second connection part 4 in the first direction is less than that of the first rotating body 1 and the second rotating body 2, it is also possible to rotate the first connection part 3 and the second connection part 4 in the first direction to a state of overlapping each other.

[0063] In some specific embodiments, the first rotating body 1 is provided with a first connecting end 11 on one side in the axial direction, and the second rotating body 2 is provided with a second connecting end 21 corresponding to the first connecting end 11 on one side in the axial direction; a rotating connection structure is provided on the first connecting end 11 and / or the second connecting end 21 to realize a rotating connection between the first rotating body 1 and the second rotating body 2.

[0064] It should be noted that the present embodiment does not limit the specific structure of the rotating connection structure. As long as the rotating connection between the first rotating body 1 and the second rotating body 2 can be achieved, a variety of rotating connection structures can be used, such as a gear meshing structure, an interference fit structure, a snap-fit ​​structure, etc.

[0065] In some specific embodiments, a toothed damping structure 81 is circumferentially provided on the first connection end 11 and the second connection end 21 to achieve different rotation angles between the first rotating body 1 and the second rotating body 2. By providing the toothed damping structure 81, it can be achieved that when the first rotating body 1 and the second rotating body 2 rotate relative to each other, the toothed damping structures 81 rub against each other to achieve a damping effect, and can further achieve control of the rotation angle between the first rotating body 1 and the second rotating body 2. The user can rotate the first rotating body 1 and the second rotating body 2 to any angle according to their own needs and then fix them. The schematic diagram of the first connecting portion 3 and the second connecting portion 4 rotating synchronously with the relative rotation between the first rotating body 1 and the second rotating body 2 is shown in FIG. Fig.12 , Fig.13 and Fig.14 The schematic diagram of the contact between the tooth-shaped damping structures 81 is shown in FIG. Figure 4 , 7 , 10 is a cross-sectional view of the rotating folding assembly in a preset second direction, wherein the preset second direction is as shown in Figure 1 , 2 , as shown in direction B in 3.

[0066] In some specific embodiments, the movable ends of the first connecting portion 3 and the second connecting portion 4 can be detachably connected to a variety of external pipes with different functional heads, so that the rotating and folding assembly can be adapted to a variety of products of different brands and models, and the user experience is better. Among them, the different functional heads of different external pipes can be as follows Fig.11 as shown in .

[0067] It should be noted that the present application does not limit the angle at which the first rotating body 1 and the second rotating body 2 can rotate relative to each other. In one embodiment, the angle range at which the first rotating body 1 and the second rotating body can rotate relative to each other may be 0-360 degrees. Fig.14 , is a schematic diagram of a state in which the first connecting portion 3 and the second connecting portion 4 rotate synchronously with the first rotating body 1 and the second rotating body 2 to achieve a 180-degree rotation.

[0068] In some specific embodiments, the first rotating body 1 is provided with a first through hole 12 in the axial direction, and the second rotating body 2 is provided with a second through hole 22 in the axial direction that is in communication with the first through hole 12 .

[0069] By providing the interconnected first through hole 12 and the second through hole 22, the user can hang the rotating folding assembly on an external hook through the through hole, or insert a keychain or other hanging accessories into the through hole, so as to make the rotating folding assembly more decorative and further broaden the functions and application scenarios of the rotating folding assembly. In one embodiment, a marker is also inserted in the interconnected first through hole 12 and the second through hole 22 to realize visual identification of the rotating folding assembly and the external pipe 9 connected thereto, so that the user can find the rotating folding assembly and the external pipe 9 more quickly. When the user has a large number of hose products that need to be classified, the hose products of different categories can be collected and stored using rotating folding assemblies of different colors, so as to realize the beautiful and orderly arrangement and storage of the hose products.

[0070] It should be noted that the present application does not limit the specific shape of the through hole. As long as the entire rotating and folding assembly can be hung on an external hook or external accessories can be inserted into the through hole, the first through hole 12 and the second through hole 22 can be a circle or a polygon, a symmetrical shape or an asymmetrical shape. For example, in a specific embodiment, the center line of the first through hole 12 and the second through hole 22 can overlap with the center line of the first rotating body 1 and the second rotating body 2.

[0071] In some specific embodiments, the first connection part 3 is detachably connected to the first rotating body 1; the second connection part 4 is detachably connected to the second rotating body 2. By detachably arranging the connection part and the rotating body, the user can set the movable ends of the first connection part 3 and the second connection part 4 to different sizes according to the sizes of different external pipes 9, and replace the first connection part 3 and / or the second connection part 4 of different sizes in different use situations to adapt and connect with different external pipes 9.

[0072] In practical applications, such as Fig.15 and Fig.16 As shown, the extension directions of the first connection part 3 and the second connection part 4 can be parallel to each other and perpendicular to the extension direction of the diameters of the first rotating body 1 and the second rotating body 2 in the axial direction. In one embodiment, a first connection part 3 and a second connection part 4 are included, and the first connection part 3 and the second connection part 4 are parallel to each other, so that the external pipes 9 connected to the first connection part 3 and the second connection part 4 can also be placed parallel to each other, so that the arrangement of the pipes can be more beautiful, and the space occupied by the first rotating body 1 and the second rotating body 2 can be minimized.

[0073] This embodiment proposes a rotating folding assembly, including a first rotating body, a second rotating body, a first connecting portion and a second connecting portion. The first rotating body and the second rotating body are connected to each other in a clockwise and / or counterclockwise direction, the first connecting portion is provided on the first rotating body, and the second connecting portion is provided on the second rotating body; the movable ends of the first connecting portion and the second connecting portion are both provided with a connecting structure for detachably connecting an external pipe fitting, so that the connected external pipe fitting can rotate synchronously with the first rotating body or the second rotating body, and the pipe fittings connected to the rotating assembly can be folded and stored during the rotation process, so that the user can uniformly store, quickly search for and select different pipe fittings products, which can effectively improve the user experience, and at the same time make the stored products more beautiful, and can be applied to many aspects of daily life.
