[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-10 The embodiment of this invention provides a simple mobile phone case ring buckle, which includes a mobile phone case body 1 and a ring buckle assembly 2, with the ring buckle assembly 2 disposed on the top of the mobile phone case body 1.
[0033] In this embodiment, the ring buckle assembly 2 includes a fixed base 21, a rotating disk 22, and a ring buckle 23. The fixed base 21 is disposed on the top of the phone case body 1. The rotating disk 22 is rotatably disposed on the fixed base 21. The ring buckle 23 is hinged to the rotating disk 22. The top of the fixed base 21 has an installation cavity 24. A decorative cover plate 25 is disposed on the installation cavity 24. A spring pin 26 is disposed on the inner side of the decorative cover plate 25. The inner peripheral wall of the rotating disk 22 is provided with a toothed groove 27. The toothed groove 27 abuts against the front end of the spring pin 26 to form a damping effect on the rotating disk 22.
[0034] In this embodiment, an annular mounting groove 28 is provided on the top of the main body 1 of the mobile phone case and on the outside of the fixed base 21 for placing the mounting rotating disk 22.
[0035] It should be noted that placing the rotating disk 22 in the annular mounting groove 28, when the ring buckle 23 and other fasteners are fastened in the rotating disk 22, can reduce the protrusion height of the ring buckle assembly 2 on the main body 1 of the phone case, thereby increasing the overall aesthetics of the phone case.
[0036] In this embodiment, the inner peripheral wall of the annular mounting groove 28 is provided with a rotating groove 29, and the outer side of the rotating disk 22 is provided with a rotating wall 210. The rotating disk 22 is inserted into the rotating groove 29 through the rotating wall 210 to achieve a rotating connection.
[0037] It should be noted that the rotating groove 29 is a groove on one side of the inner wall of the annular mounting groove 28, while the rotating wall 210 is a convex ring on the outside of the rotating disk 22 that matches the rotating groove 29. When the ring buckle 23 is rotated, the rotating disk 22 will rotate accordingly, and the rotating wall 210 on its outer side will slide in the rotating groove 29, thereby realizing the rotation of the rotating disk 22 relative to the fixed base 21.
[0038] Specifically, the rotating wall 210 of the rotating disk 22 is inserted into the rotating groove 29 on the outside of the fixed base 21 to achieve a rotating connection between the rotating disk 22 and the fixed base 21. Then, the decorative cover plate 25 is inserted into the mounting cavity 24 of the fixed base 21 through two sets of pins on the side near the mounting cavity 24 to complete the assembly of the ring buckle assembly 2.
[0039] In this embodiment, the top of the rotating disk 22 is provided with a placement groove, and the inner wall of the placement groove is provided with a hinge. The ring buckle 23 is hinged to the inside of the placement groove through the hinge.
[0040] Specifically, the ring buckle 23 is connected to the rotating disk 22 via a hinge, and the ring buckle 23 can be adjusted between 0 and 120 degrees relative to the rotating disk 22 via the hinge.
[0041] In this embodiment, the outer side of the ring buckle 23 is provided with a buckle groove 231, which makes it easy for the ring buckle 23 to be taken out from the inside of the placement groove.
[0042] In this embodiment, a spring ejector pin slot 251 is provided on the inner side of the decorative cover plate 25, and the spring ejector pin 26 is horizontally embedded in the spring ejector pin slot 251.
[0043] Specifically, the spring pin 26 is a mechanical component consisting of a spring and a pin. Its main function is to use the spring force to maintain a certain pressure or contact force on the pin, so as to achieve positioning, fixing or providing damping effect for other components.
[0044] In this embodiment, the ring buckle 23 is provided with two sets of magnets 232 on the side near the rotating disk 22, which are used to magnetically attach and fix with magnets on the charging base or vehicle bracket.
[0045] In this embodiment, both sets of magnets 232 are arc-shaped and are symmetrically distributed on the side of the ring buckle 23 near the rotating disk 22.
[0046] In this embodiment, the decorative cover plate 25 is provided with two sets of pins on the side near the mounting cavity 24. The inner wall of the mounting cavity 24 is provided with insertion holes for the two sets of pins to be inserted. The decorative cover plate 25 is detachably connected to the mounting cavity 24 by the two sets of pins.
[0047] In this embodiment, the ring buckle 23 is a ring structure, and the inner diameter of the ring buckle 23 is larger than the outer diameter of the fixing base 21.
[0048] It should be noted that the front end of the spring pin 26 on the inner side of the decorative cover plate 25 abuts against the toothed groove 27 on the inner peripheral wall of the rotating disk 22, forming a damping effect, making the rotation of the ring buckle 23 more stable and with moderate resistance, thus improving the user experience.
[0049] The working principle of the above embodiments is as follows:
[0050] (1) During installation, first, the fixed base 21 is placed on the top of the main body 1 of the mobile phone case. Then, the rotating wall 210 of the rotating disk 22 is inserted into the rotating groove 29 on the outside of the fixed base 21 to realize the rotating connection between the rotating disk 22 and the fixed base 21. Next, the decorative cover plate 25 is inserted into the mounting cavity 24 of the fixed base 21 through two sets of pins on the side near the mounting cavity 24 to complete the assembly of the ring buckle assembly 2. The ring buckle 23 is hinged in the placement groove on the top of the rotating disk 22 through a hinge. The buckle groove 231 on its outside makes it easy for the user to take the ring buckle 23 out of the placement groove for use.
[0051] (2) During use, when the ring buckle 23 is rotated, the rotating disk 22 will rotate accordingly. The outer rotating wall 210 slides in the rotating groove 29, realizing the rotation of the rotating disk 22 relative to the fixed base 21. At the same time, the front end of the spring pin 26 on the inner side of the decorative cover plate 25 abuts against the toothed groove 27 on the inner peripheral wall of the rotating disk 22, forming a damping effect, making the rotation of the ring buckle 23 more stable and with appropriate resistance, improving the user experience. In addition, the two sets of magnets 232 set on the side of the ring buckle 23 near the rotating disk 22 can be used to dock with magnets on external devices such as charging docks or car mounts to realize the magnetic fixation function.
