Description

Technical Field

[0001] The utility model relates to a cup cover which can be opened and closed by a key, and belongs to the technical field of thermos cups. Background Art

[0002] Cups are essential items in people's daily lives. Cups can be divided into many types according to their uses, such as water cups, coffee cups, hot drink cups, thermos cups, etc. Take thermos cups as an example. Thermos cups are generally made of ceramic, stainless steel or titanium alloy, and are containers with a vacuum layer on the cup body. There is a sealing cover on the top. The vacuum layer can insulate the water or other liquids in the container from the outside world to achieve the purpose of heat preservation or cold preservation. The internal structure of a thermos cup usually has many layers. The vacuum layer is used to prevent heat conduction. The outer wall of the vacuum layer is plated with silver to prevent heat radiation. A thermos cup usually includes a cup liner, an outer shell and a cup lid.

[0003] In the prior art, the cup cover is usually opened by fixing the cup cover on the cup body through a threaded connection, which has a simple structure and reliable connection. However, this threaded connection requires the user to cooperate with both hands to take off the cup cover, which is very inconvenient in some occasions. In addition, the user needs to tighten or loosen the cup cover one circle at a time before and after each use to fix and take off the cup cover, and the closing and opening efficiency is very low.

[0004] At present, there is a push-type cup cover (CN 206062786 U), which includes a push part, a sliding part connected to the push part by a conical surface so that the sliding part can move away from the push part when the push part moves downward, and an elastic band acting on the sliding part. The elastic band acts on the two sliding parts so that the two sliding parts have a tendency to approach each other, and a hook is provided on the side of the sliding part close to the push part; when in use, the push part is pressed to slide the sliding part, and the hook of the sliding part moves away from the cup body, so that the cup cover can be removed as a whole, and then water can be drunk or poured into the cup through the cup mouth. The difference between the utility model and the above-mentioned patent document is that the elastic band of the above-mentioned patent document will be stretched after being stretched for a long time, and the assembly is difficult. The sliding part must be placed first and then the elastic band is put on. During this installation process, the sliding part will be tilted, and the button will also be tilted when installed. There is also an outer cover to be pressed, which is not easy to assemble, and there is no positioning point when the sliding part is pushed open, and there is no positioning point when the sliding part is reset, and the stability is poor and it is easy to fall off. Utility Model Content

[0019] The key limit block is also provided with a limit groove that cooperates with the rotating assembly, and the limit groove is integrally connected with the valley section of the slide rail. The first mounting plate is also provided with a central magnet to absorb the key assembly so that the key assembly is limited when inserted (it can only rotate at the center position and cannot move as a whole). During the insertion process of the key, the bottom is limited by the central magnet and the two sides are limited by the limit grooves, so that it can only rotate in the valley section of the slide rail.

[0020] The utility model has the following characteristics and significant effects:
