[0029] Please refer to Figure 1-6 As shown, a suction cup structure that is easy to rotate and adjust includes a suction cup 10, a rotating ring 20, and a rotating disk 30. The upper end face of the suction cup 10 is provided with a mounting post 14. A threaded post 11 is rotatably sleeved on the outside of the mounting post 14. The rotating disk 30 is sleeved on the outside of the threaded post 11 and can drive the threaded post 11 to rotate. The center of the rotating ring 20 is provided with a first threaded hole 21 that matches the threaded post 11. The rotating disk 30 is provided with a connecting post 32. The rotating ring 20 is provided with an arc-shaped relief groove 22 that matches the connecting post 32. During assembly, the rotating ring 20 is screwed to the threaded post 11 through the first threaded hole 21. The rotating disk 30 is located between the suction cup 10 and the rotating ring 20. The connecting post 32 extends from below into the arc-shaped relief groove 22 and can move along the arc-shaped relief groove 22. By setting a threaded post 11 that can rotate relative to the suction cup 10, the phone holder can still adjust the angle of the phone even when the suction cup 10 is fixed, without having to repeatedly disassemble and assemble the phone holder, thus improving the practicality of the phone holder.

[0030] It should be noted that in actual use, a T-shaped mounting groove can be opened in the threaded post 11, and the mounting post 14 can be set as a T-shaped structure corresponding to the mounting groove. During assembly, the threaded post 11 can be sleeved on the mounting post 14 to achieve a rotatable connection.

[0031] Specifically, the upper end face of the mounting post 14 is provided with a second threaded hole 141, and the center of the threaded post 11 is provided with a first through hole 113. During assembly, the bolt 13 passes through the first through hole 113 and is threadedly connected to the second threaded hole 141. The head of the bolt 13 is blocked at the upper end of the threaded post 11.

[0032] More specifically, the threaded post 11 has an annular recess 112 at the upper end of the first through hole 113, and during assembly, the head of the bolt 13 is embedded in the annular recess 112.

[0033] Specifically, the rotating ring 20 is provided with two arc-shaped relief grooves 22, which penetrate the upper and lower end faces of the rotating ring 20, and the rotating disk 30 is provided with two connecting posts 32 corresponding to the arc-shaped relief grooves 22.

[0034] Specifically, the upper end face of the suction cup 10 is provided with a first locking block 12 arranged in a ring, and the lower end face of the rotating disk 30 is provided with a second locking block 34 arranged in a ring. A first locking groove 121 is formed between adjacent first locking blocks 12, and a second locking groove 341 is formed between adjacent second locking blocks 34. The surfaces of the first locking block 12 and the second locking block 34 are provided with arc-shaped chamfers. In use, the rotating ring 20 drives the rotating disk 30 to rotate around the mounting post 14 as the axis. When the rotation stops, the first locking block 12 is locked in the second locking groove 341, and the second locking block 34 is locked in the first locking groove 121 to prevent the rotating disk 30 and the suction cup 10 from rotating.

[0035] Specifically, a clearance space 35 is provided below the rotating disk 30 for the suction cup 10 to be pulled upward.

[0036] Specifically, the rotating disk 30 is provided with a second through hole 33, the upper end surface of the rotating disk 30 is provided with an annular protrusion 31 surrounding the second through hole 33, and the lower end surface of the rotating ring 20 is provided with an annular positioning groove 23 surrounding the first threaded hole 21. During assembly, the annular protrusion 31 is embedded in the annular positioning groove 23.

[0037] Specifically, the outer side of the threaded post 11 has a cut surface 111, and the second through hole 33 has a convex surface 331 corresponding to the cut surface 111. It should be understood that in order to enable the rotating disk 30 to drive the threaded post 11 to rotate, other non-circular structures such as a locking block can also be provided.

[0038] A mobile phone holder includes a support plate (not shown in the figure), a mobile phone fixing mechanism (not shown in the figure), and a suction cup structure as described in any one of claims 1 to 8. The mobile phone fixing mechanism (not shown in the figure) is mounted on the support plate (not shown in the figure), and the support plate (not shown in the figure) is fixedly connected to a rotating disk 30. The rotating ring 20 is located between the support plate and the rotating disk 30. In actual use, the mobile phone fixing mechanism (not shown in the figure) can be an existing structure such as a clamp or a magnetic suction.

[0039] Specifically, the connecting column 32 has an axial third threaded hole (not shown in the figure) at its center. The bolt 13 passes through the support plate and is screwed into the third threaded hole (not shown in the figure) to fix the support plate on the rotating plate 30.

[0040] In use, the phone is placed on the phone fixing mechanism (not shown in the figure). The phone angle is adjusted by rotating the support plate (not shown in the figure). Then, rotating the rotating ring 20 lifts the middle of the suction cup 10, thereby generating suction force to fix the phone holder to the mating surface. When the clamping force between the rotating ring 20 and the suction cup 10 is small, the rotating plate 30 can rotate relative to the rotating ring 20 and the suction cup 10 to adjust the phone angle. When the angle adjustment is complete, the rotating ring 20 can be rotated to increase the suction force of the suction cup 10. At the same time, the rotating plate 30 clamps between the rotating ring 20 and the suction cup 10 to enhance the stability of the phone holder until the rotating ring 20 is locked and the phone is fixed.

[0041] It should be noted that, in order to avoid interference between the connecting post 32 and the arc-shaped relief groove 22 during use, by setting the pitch of the threaded post 11 to an appropriate size, the connecting post 32 remains within the effective length of the arc-shaped relief groove 22 even when the suction cup 10 is at its minimum and maximum suction force. After the suction cup 10 is fixed, there is still an adjustment stroke between the connecting post 32 and the arc-shaped relief groove 22.

[0042] In summary, this utility model, by setting a threaded post that can rotate relative to the suction cup, enables the phone holder to still adjust the angle of the phone even when the suction cup is fixed, eliminating the need for repeated disassembly and reassembly of the phone holder and improving its practicality.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
