[0002] At present, water cups are widely used as a tool for holding liquids in people's daily life. They can be seen everywhere in offices, schools or people's hands. Most water cups have a cup lid and a cup body cover combined together by threads to make the cup tightly closed without leaking. In order to quickly open the cup lid to drink water, people have created water cups without threads. However, water cups without threads need to consider how to lock the cup lid. The method of locking the cup lid on the market basically relies on the suction of two magnets. This method is too simple. Therefore, a cup lid that opens and closes differently from water cups on the market is needed. Summary of the invention

The utility model does not need a magnet. A step portion 3 is provided on the inner wall of the cup mouth, and a sealing sleeve 6 is provided between the fixed cover in the cup cover 2 and the movable plate 4. The sealing sleeve 6 is driven to deform and expand to abut against the step portion 3. At this time, the sealing sleeve 6 is subjected to the force of the step portion 3, and people cannot smoothly pull out the cup cover 2. The cup cover 2 is locked by the rotatable rotating member 9. Some cup covers 2 on the market are locked by the rotating member 9. The product adopts a rotating method. When the control rod 5 is not upward, the outer side of the rotating member 9 is against the inner wall of the cup cover 2. When the control rod 5 is pulled upward, the rotating member 9 is partially stuck on the mounting groove 12. At this time, since the rotating member 9 is stuck and cannot actively move downward, the movable plate 4 cannot move downward. The control button 13 is pressed inward, and the inner end of the control button 13 drives the rotating member 9 to rotate. At this time, the rotating member 9 rotates inward to disengage from the mounting groove 12, the movable plate 4 can move downward, the sealing sleeve 6 is released from deformation, and the cup cover 2 can be directly removed. The inner end of the control button 13 is provided with a button spring, and the control button 13 is reset after the hand is released.

[0030] Preferably, a guide hole 14 is further opened in the control rod 5, and a guide column 15 extends from the inner end of the rotating member 9. The guide column 15 is arranged in the guide hole 14, and the guide column 15 is in the same direction as the control button 13. When the control button 13 is pressed, the rotating member 9 rotates, and the guide column 15 naturally moves inward in the guide hole 14.

[0031] Preferably, an abutment slope 16 is also formed inside the control rod 5. When the control button 13 drives the rotating member 9 to rotate inward, the inner side of the rotating member 9 abuts against the abutment slope 16. When the control rod 5 is not upward, the outer side of the rotating member 9 abuts against the inner wall of the cup cover 2. At this time, the inner side of the rotating member 9 abuts against the abutment slope 16. When the control rod 5 is upward, the inner end of the rotating member 9 rotates outward to disengage from the abutment slope 16 and protrudes from the control rod 5.

[0032] Preferably, the inner end of the control button 13 is also formed with an abutment portion 17, and an abutment surface is formed in the mounting groove 12. The abutment portion 17 abuts against the abutment surface and limits the outward movement of the control button 13, thereby limiting the outward movement distance of the control button 13, improving stability, and preventing the control button 13 from flying out after being subjected to the elastic force of the button spring.

[0033] Preferably, a circular ring portion 18 is formed on the upper end of the control rod 5, and driving the circular ring portion 18 can drive the control rod 5 to move up and down. An elliptical shell 19 is also formed above the cup cover 2, and the circular ring portion 18 is arranged in the elliptical shell 19. People can lift the control rod 5 through the circular ring portion 18 to lock the cup cover 2 by inserting a single finger, and pulling is simple and quick.

[0034] Preferably, a pressure relief hole 20 is opened in the control rod 5, and a pressure relief part 21 is arranged in the pressure relief hole 20. The lower end of the pressure relief part 21 closes the pressure relief hole 20, and the upper end of the pressure relief part 21 protrudes from the pressure relief hole 20. A pressure relief spring is also sleeved on the pressure relief part 21, and the pressure relief spring can reset the pressure relief part 21 after being pressed. The pressure relief part 21 prevents the cup cover 2 from opening suddenly when the water temperature in the cup body 1 is too high, resulting in the influence of internal and external air pressures causing the cup cover 2 to fly off and cause a safety hazard.

[0035] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
