Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, specifically to a stud-detachable suction cup structure and a mobile phone stand. Background Technology

[0002] With the widespread use of smartphones, their functions are becoming increasingly powerful, and their application scenarios are becoming more and more diverse, such as watching videos, making video calls, live streaming, and navigation. As an auxiliary tool, phone stands can help users fix their phones in a suitable position and angle, thereby freeing their hands and improving the user experience. Common phone stands include clamp-on, adhesive, magnetic (magnetic or suction cup), and placement types.

[0003] Chinese patent document (publication number: CN223463030U; publication date: October 21, 2025) discloses a mobile phone holder, which fixes the holder in place by fixing a threaded post to the upper end of a suction cup and adjusting the suction force of the suction cup by rotating a rotating ring.

[0004] The aforementioned Chinese patent has the following drawbacks: In actual use, the phone holder needs to be fixed to surfaces of different materials. Since its threaded post and suction cup are fixedly connected, it is impossible to change the suction cup according to different surface materials. When the material of the fixing surface changes, the phone holder cannot be stably fixed, thus its practicality is not strong. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a detachable stud suction cup structure and a mobile phone holder. It features a mounting groove at the lower part of the threaded stud that matches the shape of the mounting post. The mounting groove has openings on the side and bottom of the threaded stud. The threaded stud is detachably connected to the mounting post via the mounting groove, enabling quick assembly and disassembly of the suction cup and mounting post. This allows for the replacement of suction cups to match different surface materials. In actual use, the suction power of the suction cup decreases with repeated use, leading to a reduction in adsorption capacity. This structure allows for individual replacement of the suction cup, restoring adsorption capacity, reducing user costs, and further enhancing product practicality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
