[0031] To make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative effort belong to the protection scope of the present disclosure.

[0032] The rotary connection structure 10 is used for detachable mechanical connection, in particular, for scenarios requiring coaxial connection, to realize flexible disassembly and connection. As shown in the figure, the rotary connection structure 10 includes a male head 11 and a female head 12 that can cooperate with the male head 11, and the male head 11 and the female head 12 are assembled together, and the axis of the male head 11 and the axis of the female head 12 substantially coincide. Figure 1

[0033] ​The male head 11 comprises a male head body 111 configured as a cylinder extending along a male head axis 110, and the male head body 111 can also be configured as a cylindrical structure with a through hole; the female head 12 comprises a female head body 121 configured as a cylinder extending along a female head axis 120, and the female head body 121 can also be configured as a cylindrical structure with a through hole; the rotation connection structure 10 configured in this way can be sleeved on a cable, a rope, a rod, a shaft, a handle or other media that need to be protected or mechanically connected.

[0034] In order to improve the reliability of the connection between the male head 11 and the female head 12, a protruding portion 112 in a substantially circular structure, which is a circular ring structure when the male head body 111 has a through hole, is coaxially configured at the end of the male head body 111, the protruding portion 112 can extend away from the male head body 111 along the male head axis 110, and a contact surface 113 is formed at the connection between the protruding portion 112 and the male head body 111, used for abutting against the female head 12; at least one groove I 114 is formed in the circumferential direction of the protruding portion 112, and a notch groove 115 is configured on the side wall of the groove I 114 in the same direction; correspondingly, a recessed portion 122 in a substantially circular ring structure is configured at the end of the female head body 121, which cooperates with the protruding portion 112, the recessed portion 122 can extend away from the female head body 121 along the female head axis 120, and the extension distance thereof matches the extension distance of the protruding portion 112 away from the male head body 111 along the male head axis 110; the end surface of the recessed portion 122 can abut against the contact surface 113, and a protrusion I 124 in the direction of the female head axis 120 is configured on the inner ring surface of the recessed portion 122 in the circumferential direction, which corresponds to and cooperates with the groove I 114; in this configuration, the protruding portion 112 cooperates with the recessed portion 122, the protrusion I 124 cooperates with the groove I 114, the protruding portion 112 of the male head 11 is assembled into the recessed portion 122 of the female head 12, and at the same time, the protrusion I 124 on the inner ring surface of the recessed portion 122 is assembled into the corresponding groove I 114 of the protruding portion 112. Further, the protrusion I 124 is partially configured in the reverse direction as a flange I 125 that can be rotatably matched with the notch groove 115; in this configuration, the reverse-direction configured flange I 125 on the protrusion I 124 can be assembled into the forward-direction configured notch groove 115 in the groove I 114 through a rotation operation, so as to quickly and reliably coaxially connect the male head 11 and the female head 12, and the male head 11 and the female head 12 can be flexibly disassembled through a reverse rotation operation.

[0035] It should be noted that the notch groove 115 and the flange I 125 are configured in the forward direction and the reverse direction, respectively, and can also be configured in the reverse direction, so as to realize the assembly and separation of the notch groove and the flange I when performing a rotation operation.

[0036] The protrusion 112 extends a certain distance along the male connector axis 110 away from the male connector body 111. Correspondingly, the groove 122 extends a distance along the female connector axis 120 away from the female connector body 121, matching the distance of the protrusion 112. It can be seen that a longer extension distance can reduce the axial deviation between the male and female connectors. In particular, when one end of the male or female connector is connected to a component with a large mass or is frequently subjected to different loads, the male and female connectors are prone to axial deviation, shaking, or even separation.

[0037] To address the aforementioned issues, in some embodiments, an arcuate protrusion 116 is constructed within the notch 115 at the bottom of the groove I 114, along the direction of the male connector axis 110. Correspondingly, the flange I 125 on the protrusion I 124 is constructed with an arcuate groove 126 that matches the arcuate protrusion 116. This configuration ensures a reliable connection between the male connector 11 and the female connector 12, facilitates coaxial assembly of the male and female connectors, and achieves a smaller axial deviation when the extension distance of the protrusion and groove is relatively small.

[0038] In some embodiments, multiple arc-shaped protrusions 116 are constructed within the notch 115 at the bottom of the groove I 114, and correspondingly, a corresponding number of arc-shaped grooves 126 are constructed on the flange I 125 on the protrusion I 124, further ensuring a reliable connection between the male and female connectors.

[0039] The following description uses specific application examples to illustrate that this application proposes a handheld fan umbrella, particularly for use as a sunshade, which can cool the body while providing protection from heat and sun.

The U-shaped groove 225 and the fish eye ball head 223 are configured to be adjusted by 180°, and the fan head 221 can rotate around the axis connected to the fish eye ball head 223. With this configuration, the adjustment angle of the fan head 221 of the fan 22 is increased, and the fan head 221 can be adjusted to an appropriate angle for blowing and cooling.

[0043] The inside of one end of the handle 222 is configured with a recessed groove portion 226 corresponding to the protruding portion 212, and the inside of the recessed groove portion 226 is circumferentially configured with a protrusion I 227 corresponding to the recessed groove I 214 on the protruding portion 212. The protrusion I 227 and the recessed groove I 214 cooperate with each other; the protrusion I 227 is partially inversely configured as a flange I 228 that can be rotatably matched with the notch groove 215, and the flange I 228 on the protrusion I 227 is configured with an arc-shaped recess 229 that matches the arc-shaped protrusion 216.

[0044] In order to improve the mechanical strength of the handle 222, a metal sleeve can be provided outside the handle 222 to improve the mechanical connection strength and stability of the handle 222 and the fish eye ball head 223 and the protruding portion 212 on the umbrella handle body 211.

[0045] In some embodiments, the other end of the handle 222 of the fan 22 is also configured with a female head 12 structure, and the other end (bottom end) of the handle 222 of the fan 22 can be assembled to the bottom end of the umbrella handle 21 of the handheld fan umbrella 20, and the fan head 221 is located below the handle 222, which increases the installation scene of the fan and improves the flexibility of the blowing angle adjustment.
