[0002] "Spinning top medals" refer to medals designed with the spinning top as inspiration. They typically combine the shape and spinning elements of a spinning top and are used in competitions, commemorative events, or creative awards to increase the fun of the medals.

[0003] Currently, most fidget spinner medals consist of a medal body with a fidget spinner structure, enabling the spinner to rotate. The medal is usually embedded in the outer wall of the bearing in the middle of the fidget spinner, making it difficult to disassemble.

[0004] A search revealed a fidget spinner bearing fixing structure in patent application publication number CN206483136U, comprising a body; a bearing is disposed in the center of the body; a metal threaded ring is installed between the body and the bearing; a female threaded cap and a male threaded cap are respectively installed on the upper and lower sides of the body; the female threaded cap passes through the bearing and connects to the male threaded cap. The fidget spinner bearing fixing structure uses a male and female threaded cap assembly method to press the bearing end face, and a locking mechanism is provided on the metal threaded ring for easy assembly and disassembly using a coin without tools.

[0005] The gyroscope uses a threaded connection between the upper and lower covers to restrict the bearing. Although this facilitates bearing replacement, the external structure of the bearing is simple. When the gyroscope medal is mounted on the fidget spinner, the medal needs to be fixed to the outside of the bearing, which is not convenient for disassembly and assembly. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a quick-assembly and disassembly structure for a gyroscope-style medal, including a medal body 1, a bearing 2, an upper cover 3 and a lower cover 4 disposed on both sides of the medal body 1, the inner ring of the bearing 2 being fixedly connected to the lower cover 4, the bottom of the upper cover 3 being provided with a connection structure 5 for threaded connection with the lower cover 4, the outer wall of the outer ring of the bearing 2 being embedded with a fixing ring 6, and the outer ring of the fixing ring 6 being provided with a locking structure 7 for quick locking of the medal body 1;

[0026] The locking structure 7 includes a locking rod 701 and a locking hole 702. A groove 703 is provided in the middle of the medal body 1. The locking hole 702 is opened in the inner wall of the groove 703. A telescopic structure 8 is provided in the fixing ring 6 to drive the locking rod 701 to insert into the locking hole 702.

[0027] The inner ring of bearing 2 is fixed to the lower cover 4, and the outer ring is integrated with the locking structure 7 via a retaining ring 6, forming an independent unit. When bearing 2 is damaged or the medal design needs to be changed, only this unit needs to be replaced, without disassembling the entire structure, thus reducing maintenance costs.

[0028] The telescopic structure 8 includes a fixed block 801 and a slider 802. The fixed block 801 has a groove 803. One end of the locking rod 701 is fixedly connected to one side of the slider 802. The other end of the locking rod 701 passes through the fixed block 801 and is slidably connected to the fixed block 801. A spring 804 is fixed in the groove 803. One end of the spring 804 is fixedly connected to the other side of the slider 802.

[0029] Spring 804 is placed in slide groove 803 and is normally in the extended state, pushing slider 802 to keep locking rod 701 in the locked position inserted into lock hole 702.

[0030] The locking rod 701 and the locking hole 702 are both provided in two sets, and the locking hole 702 is symmetrically arranged on both sides of the medal body 1.

[0031] The symmetrical design of the locking rod 701 and the locking hole 702 ensures balanced force distribution and avoids single-point failure.

[0032] A paddle 805 is fixed on the upper surface of the slider 802. A limit plate 806 is fixed above the fixed block 801 by screws. A limit groove 807 is opened in the middle of the limit plate 806. The paddle 805 passes through the limit plate 806 through the limit groove 807.

[0033] When the paddle 805 is moved, the spring 804 slides along the groove 803 and is compressed, and the locking rod 701 retracts synchronously and disengages from the locking hole 702. The limiting plate 806 constrains the movement trajectory of the paddle 805 through the limiting groove 807 to prevent the slider 802 from disengaging.

[0034] The connecting structure 5 includes an upper cylinder 501 and a lower cylinder 502. The upper cylinder 501 is integrally formed at the bottom of the upper cover 3, and the lower cylinder 502 is integrally formed in the middle of the lower cover 4. The lower cylinder 502 is embedded in the inner wall of the inner ring of the bearing 2.

[0035] The upper cylinder 501 at the bottom of the upper cover 3 and the lower cylinder 502 of the lower cover 4 are screwed together. Rotating the upper cover 3 completes the overall sealing or disassembly. The threaded connection provides reliable fixation and intuitive operation.

[0036] The lower surface of the upper cover 3 is provided with a relief groove 301 for protecting the telescopic structure 8, and the relief groove 301 is arranged in a ring.

[0037] The upper cover 3 has an annular clearance groove 301 inside, which avoids contact with telescopic components such as the paddle 805 and the limiting plate 806 when tightened, ensuring the freedom of movement of the locking structure 7. At the same time, after the upper cover 3 is tightened, there is a gap between the side of the upper cover 3 closest to the medal body 1 and the medal body 1 to avoid affecting the rotation of the medal body 1.

[0038] One end of the lower cover 4 has a circular hole 401, and both the lower cover 4 and the medal body 1 are regular polygons.

[0039] The round hole 401 of the lower cover 4 is used for hanging or attaching decorative parts to expand functionality.

[0040] In use, after the user unscrews the top cover 3, they can directly move the lever 805. The limiting groove 807 limits the lever 805, and the lever 805 drives the slider 802 to slide in the slide groove 803, compressing the spring 804, causing the locking rod 701 to exit from the locking hole 702 in the groove wall of the medal body 1, releasing the mechanical lock between the bearing 2 and the medal body 1, and achieving rapid separation;

[0041] During installation, align bearing 2 with the groove 703 of medal body 1. After releasing the lever 805, spring 804 rebounds, pushing slider 802 to reset, and locking rod 701 automatically inserts into lock hole 702 to complete locking.

[0042] Install the top cover 3: The top cover 3 has an annular clearance groove 301 inside, which avoids contact with telescopic components such as the paddle 805 and the limit plate 806 when tightened. At the same time, after the top cover 3 is tightened, there is a gap between the side of the top cover 3 closest to the medal body 1 and the medal body 1 to avoid affecting the rotation of the medal body 1.

[0043] The bearing 2 of the device forms a replaceable unit with the medal body 1, which can be adapted to different medal designs and is also convenient for individual maintenance or replacement of damaged parts.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
