Description

Container cover and water cup Technical Field The invention relates to the technical field of heat preservation containers, in particular to a container cover and a water cup. Background The heat preservation container is a necessity in daily life, and the heat preservation container is required to store water or preserve heat under the conditions of travel, household and the like, the upper cover of the existing container with the heat preservation function is connected to the cup body or the tank body in a threaded connection mode, the threaded connection mode needs two hands to operate when the cover is opened, one hand is required to hold the cup body, and the other hand is used for unscrewing the cover. The threaded connection mode is quite inconvenient to use in certain occasions, for example, a driver wants to open a cover to use in the driving process, and the cover is unsafe. For this situation, in the prior art, some heat-insulating containers capable of being operated by one hand to open the cup cover are also appeared, for example, the "cup cover and container with pressure release function" disclosed in chinese patent application No. 202222731396.X (bulletin number CN 218528395U) includes a cover body and a flip hinged on the cover body, a water drinking port is opened on the cover body, the flip can close the water drinking port in a downward turning state, a pressure release channel capable of conducting the water drinking port is opened on the flip, a pressure release valve is arranged in the pressure release channel, and a trigger device capable of triggering the pressure release valve to open or close the pressure release channel is further arranged on the flip. In the structure, the lock button arranged on the flip cover is in a sliding manner, so that the lock button can lock the flip cover on the cover body when the flip cover is in a downward flip state, and the lock button can be pushed to enable the flip cover to be in an unlocking state, and therefore the cup cover can be opened by one hand smoothly. However, there is a problem in that since the end portion for pressing on the lock knob is exposed to the side portion of the lid, there is often a problem in that the lid is accidentally opened due to the lock knob being moved inward by misuse of the end portion of the lock knob during daily use, thereby causing unnecessary water leakage. Therefore, how to provide a cup cover or a water cup which has a reasonable structure, can realize the opening of the cup cover by one hand, and can effectively prevent water leakage caused by accidental opening of the cup cover due to the fact that a lock button is touched by mistake is a problem to be solved by a person skilled in the art. Disclosure of Invention The first technical problem to be solved by the invention is to provide a container cover which is reasonable in structure, can be quickly opened by one hand, and can be effectively prevented from being accidentally opened due to the fact that a lock button is accidentally touched. A second technical problem to be solved by the present invention is to provide a water cup with the container lid according to the above state of the art. The invention solves the first technical problem by adopting the technical scheme that: the utility model provides a container lid, includes the lid and overturns the uncapping subassembly of locating on the lid, be equipped with the delivery port on the lid, uncapping subassembly can seal the delivery port or open the delivery port in the upset in-process, its characterized in that: the cover opening assembly comprises a rotatable limiting piece and a lock button capable of transversely moving, the rotation axis of the limiting piece is parallel or approximately parallel to the moving direction of the lock button, the lock button can enable the cover opening assembly to form a locking state for closing the water outlet or an unlocking state for opening the water outlet in the transverse moving process, and the limiting piece can prevent the lock button from moving towards the unlocking direction when rotating to a first angle and allow the lock button to move towards the unlocking direction when rotating to a second angle. In order to enable the lock button to better form a locking state or an unlocking state between the cover opening assembly and the cover body, preferably, a buckle is formed on the lock button, a clamping groove matched with the buckle is formed on the inner wall of the water outlet, when the lock button moves to a set position in the locking direction, the buckle can be matched with the clamping groove to enable the cover opening assembly to be locked on the cover body, and when the lock button moves to the set position in the unlocking direction, the buckle can be separated from the clamping groove to enable the cover opening assembly to be opened. In order to optimize the overall structure of the cover opening assembly, the lock button an
