[0028] Please refer toFigures 1 - 3 , an embodiment of the present utility model provides a magnetic universal coupling to solve the problems that the structure of the existing support member is relatively complex, the disassembly and installation are cumbersome, and the angle adjustment flexibility is poor.

[0029] Specifically, please refer to Figure 1 which is a perspective view of a magnetic universal coupling provided by an embodiment of the present utility model. The present utility model provides a magnetic universal coupling, which includes a first connecting member 10 and a second connecting member 20 that are cooperatively connected. The first connecting member 10 and the second connecting member 20 are respectively connected to the equipment and the equipment assembly plane to fix and position the equipment at an appropriate position. Figure 2 which is an exploded view of a magnetic universal coupling provided by an embodiment of the present utility model. The first connecting member 10 includes a first magnetic attraction portion 11 and a first connecting portion 12 connected to the first magnetic attraction portion 11; the second connecting portion 22 includes a second magnetic attraction portion 21 and a second connecting portion 22 connected to the second magnetic attraction portion 21. The second connecting portion 22 is rotatably fixed to the first connecting portion 12. By providing that the first connecting member 10 includes the first magnetic attraction portion 11, and the first connecting member 10 includes the first magnetic attraction portion 11, the first magnetic attraction portion 11 and the second magnetic attraction portion 21 respectively perform magnetic adsorption on the equipment and the equipment assembly plane. The magnetic adsorption connection provides a stable fixing force, which can ensure that the equipment is firmly attached to the assembly plane, avoid accidental detachment, reduce the cumbersome steps of traditional screw fixing or mechanical fastening, and improve the efficiency of assembly and disassembly. By providing that the first connecting member 10 includes the first connecting portion 12 and the second connecting member 20 includes the second connecting portion 22, and the second connecting portion 22 is rotatably fixed to the first connecting portion 12, the connection manner in which the second connecting portion 22 is rotatably fixed to the first connecting portion 12 enables the second connecting member 20 to be adjusted at multiple angles relative to the first connecting member 10, increasing the flexibility of angle adjustment during the actual use of the equipment, and can adapt to different environments and usage requirements. It not only improves the functionality and user experience of the product, but also ensures the safety and reliability of the structure.

[0030] A magnetic universal coupling provided by the present utility model, by providing that the first connecting member 10 includes the first magnetic attraction portion 11, and the first connecting member 10 includes the first magnetic attraction portion 11, the first magnetic attraction portion 11 and the second magnetic attraction portion 21 can respectively perform magnetic adsorption on the equipment and the equipment assembly plane to fix and position the equipment at an appropriate position; by providing that the first connecting member 10 includes the first connecting portion 12 and the second connecting member 20 includes the second connecting portion 22, and the second connecting portion 22 is rotatably fixed to the first connecting portion 12, the flexibility of angle adjustment between the first connecting member 10 and the second connecting member 20 is improved, and the structure is small and convenient to use.

[0031] As a further improvement of the present utility model, please refer to Figure 3, the first connecting portion 12 includes an annular housing 121. Inside the annular housing 121, there are a first cavity 122 and a second cavity 123 that are interconnected. The first cavity 122 is in contact with the first magnetic attraction portion 11. By providing the first cavity 122 and the second cavity 123 that are interconnected inside the annular housing 121, the first cavity 122 serves as an accommodation chamber for the second connecting portion 22. The second connecting portion 22 can move within the first cavity 122 to achieve the movable connection between the first connecting portion 12 and the second connecting portion 22. The contact between the first cavity 122 and the first magnetic attraction portion 11 ensures the structural stability of the first cavity 122 and the connection reliability of the movable connection between the first connecting portion 12 and the second connecting portion 22.

[0032] As a further improvement of the present utility model, the first cavity 122 is a hemispherical cavity. By providing the first cavity 122 as a hemispherical cavity, the first connecting portion 12 can have offsets in multiple directions within the first cavity 122, thereby adapting to more complex angular changes and movements.

[0033] As a further improvement of the present utility model, the second connecting portion 22 includes a spherical connecting head 221 and a connecting shaft 222 that are connected to each other. The spherical connecting head 221 is rotatably fixed in the first cavity 122, and the connecting shaft 222 is connected to the second magnetic attraction portion 21. By providing the spherical connecting head 221 rotatably fixed in the first cavity 122, the spherical connecting head 221 cooperates with the hemispherical first cavity 122. The spherical connecting head 221 rotates in the hemispherical first cavity 122, driving the connecting shaft 222 to offset in multiple directions, thereby adjusting the deflection angle of the second magnetic attraction portion 21 and realizing the adjustment of the deflection angle of the magnetic coupling device. At the same time, the spherical designs of the spherical connecting head 221 and the hemispherical first cavity 122 can withstand larger loads and maintain stability during high-speed operation.

[0034] As a further improvement of the present utility model, the second cavity 123 is a cylindrical cavity. The inner diameter of the second cavity 123 at the end close to the first cavity 122 is smaller than the inner diameter of the second cavity 123 at the end far from the first cavity 122. By providing the inner diameter of the second cavity 123 at the end close to the first cavity 122 to be smaller than the inner diameter of the second cavity 123 at the end far from the first cavity 122, the second cavity 123 has an open shape, reducing the limitation of the second cavity 123 on the deflection angle of the connecting shaft 222, enabling the connecting shaft 222 to deflect a larger angle, and expanding the angle adjustment range of the magnetic universal coupling.

[0035] As a further improvement of the present invention, a first magnetic member 111 is attached to one end of the first magnetic portion 11 away from the first connecting portion 12, and the first magnetic member 111 is a permanent magnet or an electromagnet. Of course, the first magnetic portion 11 can also be completely composed of a permanent magnet.

[0036] As a further improvement of the present invention, a second magnetic member 211 is attached to one end of the second magnetic portion 21 away from the second connecting portion 22, and the second magnetic member 211 is a permanent magnet or an electromagnet. Of course, the second magnetic portion 21 can also be completely composed of a permanent magnet.

[0037] As a further improvement of the present invention, first reinforcing members 1211 are arranged radially at intervals on the outer wall of the annular shell 121. By arranging the first reinforcing members 1211 radially at intervals on the outer wall of the annular shell 121, the structural stability of the first connecting part 12 is ensured when the first connecting part 12 is movably connected to the second connecting part 22, and it is ensured that it will not be easily loosened at a preset rotation angle, thereby ensuring the stability of the connection.

[0038] As a further improvement of the present invention, a second reinforcement member 2221 is provided at the connection between the connecting shaft 222 and the second magnetic attraction part 21, and the second reinforcement member 2221 is a conical structure. By providing the second reinforcement member 2221 at the connection between the connecting shaft 222 and the second magnetic attraction part 21, the connection stability between the connecting shaft 222 and the second magnetic attraction part 21 is improved, ensuring that the connecting shaft 222 will not break when the angle is adjusted. By setting the second reinforcement member 2221 as a conical structure, the stability of the connection between the connecting shaft 222 and the second magnetic attraction part 21 is further increased. When the connecting shaft 222 is subjected to lateral or torsional force when the angle is adjusted, the conical outward expansion shape of the second reinforcement member 2221 provides a larger contact area, which helps to improve the rigidity of the overall structure of the magnetic universal coupling and reduce shaking and deformation.

[0039] As a further improvement of the present invention, the first magnetic attraction part 11 and the second magnetic attraction part 21 respectively attract the equipment to be used and the equipment assembly plane. The equipment to be used includes an induction lamp, a mobile phone and an induction box 212. Preferably, the second magnetic attraction part 21 is magnetically connected to the induction box 212.

[0040] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above embodiments only represent the preferred embodiments of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
