Technical Field

[0001] The utility model relates to the technical field of drinking cups, in particular to a locking structure of a drinking cup lid. Background Art

[0002] In the current prior art, the connection method between the cup lid and the cup body is generally a thread. However, the connection method of the thread is less convenient during use, and the locking is relatively unreliable. Both screwing the lid too tightly and too loosely may cause some adverse consequences, such as being too tight and difficult to unscrew. During the process of screwing tightly, when the teeth are not aligned or the screwing is not in place, the cup lid cannot be tightly connected to the cup body, resulting in water leakage at the cup lid.

[0003] Chinese Patent Grant Publication No.: CN215015895U, Grant Publication Date: December 7, 2021, discloses a double-locking cup lid and a water cup, connecting a straw. The cup lid is provided with a locking groove with an upward opening. A support member is hinged in the locking groove. One end of the straw extends into the locking groove to connect the support member. It is characterized in that it further includes a first locking member and a second locking member. Among them, the first locking member is connected to the support member, and the first locking member is engaged with the locking groove to position the support member and the straw in the locking groove; when the first locking member is separated from the locking groove, the straw restores under its own elastic force; the second locking member is connected to the first locking member, and the second locking member is engaged with the locking groove to lock the first locking member; when the second locking member is separated from the locking groove, the first locking member can be separated from the locking groove. The disadvantage of this utility model is that the connection between the cup lid and the cup body still uses a thread connection, and it is easy to occur that the screwing is not in place. Summary of the Utility Model

[0004] The utility model aims to overcome the deficiency that it is easy to occur that the screwing is not in place in the prior art, and provides a locking structure of a drinking cup lid that directly fixes the cup lid after buckling.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The cup lid is connected to the cup body through the clamping structure. The locking component is installed on the cup lid, and the lower end of the locking component is connected to the cup body.

[0007] A cup cover is installed at the upper end of the cup body. The cup cover is directly placed on the upper end of the cup body without the need for screwing connection through threads. The connection between the cup cover and the cup body can be directly achieved through a snap connection structure to ensure that there is no water leakage from the cup cover. After the cup cover is connected to the cup body, the cup cover is locked at the upper end of the cup body through a locking component to prevent the cup cover from falling due to external force. The cup cover and the cup body can be quickly connected, reducing threaded connections and preventing the situation where the cup cover is not screwed in place properly, achieving the purpose of fixing the cup cover after direct snapping.

[0008] Preferably, the snap connection structure includes snap columns and snap grooves. A plurality of snap grooves are installed on the inner wall of the cup cover and are evenly distributed in a circumferential manner. The shape of the snap groove is L-shaped.
