In order to solve the technical problems, the utility model adopts the following technical scheme:

The cup cover with the locking mechanism comprises a threaded cover and a flip cover, wherein a water drinking port is arranged on the threaded cover, and a button is arranged on the flip cover; one end of the flip cover is hinged with the threaded cover through a pin rotating shaft, a torsion spring is arranged on the pin rotating shaft, and the torsion spring is in a compression deformation state when the flip cover is closed;

The flip cover is provided with a lock catch, the lock catch is rotationally connected with the flip cover, and the lock catch is used for limiting the rotation of the button;

When the flip is closed, the flip is closed to shield the drinking water port, the button is clamped with the drinking water port, the flip is limited on the threaded cover, and the lock catch is horizontally rotated to lock the limiting button;

When the flip is opened, the lock catch is firstly rotated horizontally, so that the button is separated from the limit of the lock catch, the flip is turned over and opened under the action of the torsion spring, the button is driven to separate from the drinking water port when the flip rotates, and the button and the lock catch are turned over synchronously along with the flip.

Further, a groove part is arranged on the lock catch, and a clamping part matched with the groove part is arranged on the button; when the limiting button is locked, the clamping part is limited on the groove part, so that the limiting button is turned upwards.

When the flip needs to be opened, the lock catch is rotated to a position where the clamping part is completely separated from the groove part, the flip is turned over and opened under the action of the torsion spring, and the flip is turned over to drive the button, so that the button is separated from the drinking water port, and the button and the lock catch are turned over together with the flip, so that the screw cap is separated. The clamping part is arranged at the middle position of the button, the groove part is also arranged at the middle position of the lock catch, the lock catch horizontally rotates leftwards or rightwards relative to the button, and the groove part can be completely separated from the clamping part, so that the operation is convenient.
