一种具备旋转功能的环形立体展览柜
By combining eddy current damping with dynamic adjustment of centrifugal blocks, a rotation speed limiting device and an overrunning clutch are used to solve the problems of unstable speed control and exhibit safety in traditional circular display cases. This enables seamless switching between manual speed change, pause, and reverse rotation, improving the display effect and equipment lifespan of the display case.

AI Technical Summary
Traditional circular display cases have a single rotating function, which cannot meet the needs of manual intervention. The rotation speed control is unstable, which can easily lead to exhibits sliding, colliding or falling. In addition, the display panel design lacks targeted protection and cannot flexibly divide the display into sections.
The rotation speed limiting device combines eddy current damping with dynamic adjustment of centrifugal blocks. Combined with an overrunning clutch and active drive device, it achieves seamless switching between manual speed change, pause and reverse rotation. Equipped with a tilting pressure plate, angle-matched contact blocks and damping rod design, it ensures smooth rotation.
It achieves stable display of exhibits, improves the ease of operation and reliability of the equipment, reduces the risk of damage to exhibits, and is suitable for flexible display in a variety of venues.
