[0031] As a further implementation of this solution, there are two track components 2. The limiting track 21 is symmetrically arranged at the upper end of the display case 1. The limiting track 21 is located directly above the magnetic track 3. The inner side and upper side of the limiting track 21 are in close contact with the decorative frame body 41. There is a gap between the inner side of the limiting track 21 and the left side of the decorative frame body 41. The two symmetrical limiting tracks 21 provide stable lateral limiting and support for the decorative frame body 41 to prevent it from shaking. At the same time, the limiting track 21 cooperates with the magnetic track 3 to accurately position the decorative frame body 41, ensuring that it is firmly installed and easy to disassemble and adjust.

[0032] As a further implementation of this scheme, the side cross-section of the rotating wheel 24 is "I" shaped. The inner side of the rotating wheel 24 is rotatably connected to the threaded rod 461. The knob 463 is partially sleeved on the outer side of the rotating wheel 24 near the center of the limiting rail 21. There is a gap between the rotating wheel 24 and the decorative frame body 41. The "I" shaped rotating wheel 24 increases the contact area with the slide groove 22 and improves the sliding stability. The rotating wheel 24 is connected to the threaded rod 461. The knob 463 is sleeved on the outer side of the rotating wheel 24, which facilitates the connection and fixation of the decorative frame body 41 through the knob 463. The gap between the rotating wheel 24 and the decorative frame body 41 avoids interference, ensures the flexible rotation of the rotating wheel 24, and improves the reliability of the device.

[0033] As a further implementation of this solution, two fixed shafts 42 are provided on the inner side of the decorative frame body 41. The fixed shafts 42 are symmetrically arranged on the inner side of the decorative frame body 41. The outer side of the rotating cylinder 43 is in close contact with the inner side of the guide rail groove 23. The rotating cylinder 43 has the same length as the fixed shafts 42. The rotating cylinder 43 is set at the center line of the limiting rail 21. The two fixed shafts 42 are symmetrically arranged to provide stable support for the rotating cylinder 43 and ensure its smooth rotation. The rotating cylinder 43 is in close contact with the guide rail groove 23 and accurately guides the decorative frame body 41. The rotating cylinder 43 has the same length as the fixed shafts 42 and is centered, so that the force is evenly distributed and the load-bearing capacity and structural strength are enhanced.

[0034] As a further implementation of this scheme, there are two large magnet blocks 44. The large magnet blocks 44 are symmetrically arranged inside the decorative frame body 41. The lower end of the large magnet blocks 44 is on the same horizontal plane as the lower end of the decorative frame body 41. The large magnet blocks 44 and the magnetic track 3 are magnetically repelled. The large magnet blocks 44 are located directly below the threaded rod 461. The threaded holes opened inside the decorative frame body 41 in the space where the large magnet blocks 44 are located are interconnected. The symmetrically arranged large magnet blocks 44 generate magnetic repulsion force, which provides buoyancy for the decorative frame body 41, reduces friction with the magnetic track 3, and facilitates movement and position adjustment. The large magnet blocks 44 are located directly below the threaded rod 461, and the threaded holes are interconnected to ensure smooth connection of the threaded rod 461, enhance the magnetic repulsion effect, and improve the stability and flexibility of movement.

[0035] As a further implementation of this solution, there are two scraper blades 45. The scraper blades 45 are symmetrically arranged in pairs on the outside of the decorative frame body 41. The lower side of the scraper blade 45 is in close contact with the magnetic rail 3. The scraper blade 45 is at a 30° angle to the front or rear side of the decorative frame component 4 it is in close contact with. The length of the scraper blade 45 is the same as the width of the magnetic rail 3. The symmetrically arranged scraper blades 45 can effectively clean the dust on the magnetic rail 3 and maintain the stability of the magnetic repulsion. The scraper blade 45 is in close contact with the magnetic rail 3 at a 30° angle, which improves the dust removal efficiency. The length of the scraper blade 45 is the same as the width of the magnetic rail 3, which ensures thorough cleaning and smooth movement of the decorative frame body 41.

[0036] As a further implementation of this solution, the small magnet 462 rotates in the threaded hole on the inner side of the decorative frame body 41. The small magnet 462 and the large magnet 44 are magnetically repelled and attracted on their respective sides. The small magnet 462 is positioned directly below the fixed shaft 42. The knob 463 is in close contact with the outer side of the limiting rail 21. The small magnet 462 rotates in the threaded hole, and the magnetic repulsion and attraction between the small magnet 462 and the large magnet 44 provides resistance to the rotation of the threaded rod 461, preventing excessive rotation, accurately controlling the position, and ensuring the stable fixation of the decorative frame body 41. The small magnet 462 is positioned below the fixed shaft 42 and does not affect the rotation of the rotating drum 43. The knob 463 is in close contact with the limiting rail 21, which is convenient for operation and has a stable structure.

[0037] Workflow: When using this detachable display case top decorative frame, the threaded rod 461 can be removed from the inside of the decorative frame body 41. After decorating the decorative frame body 41, the user can slide the decorative frame body 41 into the two limiting rails 21 at the top of 11. First, align the rotating cylinder 43, which is rotatably connected to the inside of the decorative frame body 41 via the fixed shaft 42, with the guide rail grooves 23 opened on the inside of the two limiting rails 21 at the top of the display case 1. Then, slide the rotating cylinder 43 tightly against the inside of the guide rail grooves 23. The guide rail grooves 23 can guide and position the entire decorative frame body 41 through the rotating cylinder 43. After the main body 41 of the decorative frame moves into the inner side of the two limiting tracks 21, it is subjected to the magnetic repulsion force of the two symmetrically arranged magnetic tracks 3 above the display case 1. The large magnet 44 inside the main body 41 of the decorative frame is passively pushed upward by the magnetic repulsion, thus ensuring that the magnetic track 3 and the bottom of the main body 41 of the decorative frame maintain a certain distance. Then, the threaded rod 461 fixedly connected to the knob 463 is inserted into the rotating wheel 24 in the slide groove 22 opened inside the limiting track 21, and the threaded rod 461 is continued to be inserted, so that the threaded rod 461 rotates and is inserted into the spiral groove opened inside the main body 41 of the decorative frame, thus connecting the threaded rod 461 to the main body 41 of the decorative frame. Together, until the knob 463 is rotated so that one side of the knob 463 is in close contact with the limiting rail 21, the position of the decorative frame body 41 can be fixed and restricted, thereby realizing the use of the decorative frame on the top of the display case. If the position of the decorative frame body 41 needs to be adjusted as needed, simply rotate the knob 463 in the opposite direction, so that the knob 463 drives the threaded rod 461 to rotate inside the decorative frame body 41, until the threaded rod 461 drives the small magnet 462 fixedly connected to it to the position where the large magnet 44 communicates with the threaded hole inside the decorative frame body 41. Due to the magnetic attraction between the small magnet 462 and the upper side of the large magnet 44, the knob 463 drives the threaded rod When the rotation of knob 463 encounters resistance, it can be stopped. Then, the decorative frame body 41 is pushed. The decorative frame body 41 slides magnetically above the magnetic track 3 via the large magnet 44 on its inner side. At the same time, the rotating wheel 24 slides directionally inside the guide rail groove 23, and the rotating wheel 24 on the outer side of the threaded rod 461 slides inside the slide groove 22. As the decorative frame body 41 moves, the scraper 45 on the outer side of the decorative frame body 41 can scrape the dust above the magnetic track 3 to ensure the magnetic repulsion between the large magnet 44 and the magnetic track 3. This device ensures the smooth movement of the decorative frame body 41 and provides certain limiting assistance for the smooth movement of the decorative frame body 41.

[0038] 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.
