AI Technical Summary
The lids of existing insulated cups are prone to loosening due to rotation, which can lead to liquid leakage, posing a safety risk, especially to children and when used in variable environments.
Design an idle-rotating cup lid. By setting a rotating shaft and a spring between the inner cup lid and the outer cup lid shell, the engagement and disengagement of the rotating shaft's teeth with the gear ring are used to ensure the stability of the cup lid when opening and closing, and to prevent loosening.
It effectively prevents liquid leakage caused by loosening when the lid is closed, improving safety, especially for children and in changing environments.

Abstract
Claims
1. A turn -on cup cover installed on a liquid container, the turn-on cup cover comprising an upper cup cover and a lower cup cover, characterized in that, The lower cup lid includes: The inner cup lid is equipped with a spring and a rotating shaft that abuts against the spring. The outer surface of the rotating shaft is provided with multiple protruding teeth. A cup lid outer shell that fits onto the surface of the inner cup lid, wherein a gear ring is provided inside the cup lid outer shell; When the upper cup lid is opened, the locking teeth of the rotating shaft engage with the gear ring inside the cup lid shell, so that the inner cup lid is fixedly connected to the cup lid shell. When the upper cup lid is closed, the upper cup lid squeezes the rotating shaft, and the locking teeth of the rotating shaft separate from the gear ring inside the cup lid shell, so that the inner cup lid is connected to the cup lid shell in free rotation, and the spring is compressed and provides a restoring force for the rotating shaft to return to its original position.
2. A turntable cup cover as defined in claim 1, wherein The inner cup lid has a protruding first ring, and the outer shell of the cup lid has multiple support blocks. The support blocks are connected to the first ring for limiting, so that the inner cup lid is snapped into the outer shell of the cup lid.
3. A turntable cup cover as defined in claim 2, wherein The support block has a cross-section that matches the surface of the first annulus.
4. A turntable cup cover as defined in claim 2, wherein The inner cup lid has a protruding second ring, and the first ring and the second ring form an annular groove. The upper cup lid and the outer shell of the cup lid rotate freely along the annular groove.
5. A turntable cup cover as defined in claim 1, wherein The inner cup lid has a threaded structure for connecting to the liquid container.
6. A turntable cup cover as defined in claim 1, wherein The inner cup lid is equipped with a sealing gasket.
7. A turntable cup cover as defined in claim 1, wherein The inner cup lid is provided with a protruding limiting block, and the rotating shaft is provided with a recessed limiting groove. The limiting block and the limiting groove are connected in a limiting manner so that the rotating shaft is connected to the inner cup lid in a limiting manner.
8. A turntable cup holder as defined in claim 1, wherein A force-bearing platform is provided below the rotating shaft, and the force-bearing platform abuts against the spring.
9. A turntable cup cover as defined in claim 1, wherein Both the inner cup lid and the outer cup lid shell are provided with straw openings.
10. A liquid container characterized by comprising: The liquid container is provided with an empty cup lid as described in any one of claims 1-9.
