Description

Technical Field

[0001] This utility model relates to a key-operated cup lid with a locking structure. It belongs to the technical field of thermos cups. Background Technology

[0002] Cups are essential items in people's daily lives. Cups can be categorized in various ways according to their use, such as water cups, coffee cups, hot drink cups, and insulated cups. Taking insulated cups as an example, they are generally containers with a vacuum layer inside the cup body, made of materials such as ceramic, stainless steel, or titanium alloy, and a sealed lid. The vacuum layer insulates the water or other liquids inside the container from the outside environment, achieving the purpose of keeping them hot or cold. The internal structure of an insulated cup usually has many layers; the vacuum layer prevents heat conduction, and the outer wall of the vacuum layer is plated with silver to block heat radiation. An insulated cup typically includes a liner, an outer shell, and a lid.

[0003] In existing technologies, cup lids are typically fixed to the cup body via a threaded connection, a simple and reliable method. However, this threaded connection requires the user to use both hands to remove the lid, which is inconvenient in some situations. Furthermore, users need to tighten or loosen the lid repeatedly before and after each use, resulting in very low efficiency in both closing and opening.

[0004] Currently, there is a press-type cup lid (CN 206062786 U), which includes a pressing part, a sliding part that is slidably connected to the pressing part via a conical surface so that it can move away from the pressing part when the pressing part moves downward, and an elastic band acting on the sliding part. The elastic band acts on the two sliding parts, causing the two sliding parts to tend to move closer to each other. A hook is provided on the side of the sliding part near the pressing part. In use, by pressing the pressing part, the sliding part slides, and the hook of the sliding part moves away from the cup body, so that the cup lid can be removed as a whole, and then drinking or pouring water into the cup through the mouth. The difference between this utility model and the above-mentioned patent literature is that the elastic band in the above-mentioned patent literature will stretch after being stretched for a long time. 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 lift up, and the button will also lift up after installation. There is also an outer cover to press down, making assembly difficult. Moreover, there is no positioning point for the sliding part to be pushed open, and there is no positioning point for the sliding part to be returned to its original position, resulting in poor stability and easy detachment. Utility Model Content

[0005] This invention proposes a cup lid that opens and closes by inserting a key assembly into the mounting hole of the cup lid and rotating the key assembly. During the rotation, air can be released simultaneously. The locking assembly and the key assembly work together to create a cup lid with a locking structure that has multiple functions, thus solving the problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A key-operated cup lid with a locking structure includes an upper cup lid, a lower cup lid, and a cup body with mounting holes.

[0008] The lower cup lid includes an outer wall of the lower cup lid and a first mounting plate installed inside the lower cup lid; a limiting groove is formed between the outer wall of the lower cup lid and the first mounting plate;

[0009] The lower cup lid is equipped with multiple locking components and key limiting components. The locking components include a first vertical member and a second vertical member connected in sequence. The second vertical member is located in the limiting groove and is equipped with a hook that can be separated from or closed from the cup body. The number of locking components and key limiting components is set to 2 each, and they are arranged symmetrically.

[0010] The key limiting assembly includes a key limiting block and a slide rail valley section formed on the key limiting block;

[0011] A key assembly is installed in the mounting hole; a locking component for locking or releasing the key assembly is installed on the side of the key assembly. The locking component includes a pressing block and a locking rod located outside the cup lid and convenient for the user to press. The locking rod is connected to the locking block; one end of the pressing block penetrates through the outer wall of the lower cup lid and is operated by the user pressing it.

[0012] The key assembly includes a handle for easy user rotation and a rotating component located below the upper lid. The rotating component includes a locking hole that engages with the locking block to separate or lock the locking component from the key assembly, and toothed peaks that rotate at the upper limit of the slide rail's valley section to push the locking component outwards, thus separating the lid from the cup body. When the locking block is engaged in the locking hole, the key assembly cannot move up or down or rotate. Only when the locking block separates from the locking hole can the key assembly move up or down and rotate.

[0013] The number of locking components and key limiting components are two each, and they are arranged in a cross pattern. The rotating component also includes a toothed valley, and the key limiting block also has a slide rail peak section.

[0014] The length of the two tooth peaks is greater than the distance between the two locking components. In the rotating component, the length of the two tooth peaks is greater than the distance between the two locking components, so that the tooth peaks can push the locking components outward during rotation.

[0015] A first spring is installed on one side of the locking assembly, and the opposite side of the first spring is installed on the outer wall of the lower cup lid or on the first mounting plate; the first spring is provided for the reset of the locking assembly.

[0016] A first support column is installed on the outer wall of the lower cup lid, a first connecting column is installed on the opposite side of the first vertical member, a second connecting column is installed on the first support column, and a first spring is sleeved on the first connecting column and the second connecting column, penetrating the second vertical member.

[0017] A first support column is installed on the first mounting plate, a first connecting column is installed on the opposite side of the first vertical member, a second connecting column is installed on the first support column, and a first spring is sleeved on the first connecting column and the second connecting column.

[0018] A second mounting plate is installed at the lower end of the first mounting plate, and an elastic ring is installed between the second mounting plate and the first mounting plate. The lower end of the rotating assembly is also provided with a lower contact. An exhaust valve is installed on the second mounting plate. The upper end of the exhaust valve passes through the first mounting plate and is connected to an upper contact that cooperates with the lower contact to realize exhaust. The lower end of the exhaust valve passes through the second mounting plate and is fixed by bolts. A second spring is sleeved on the outside of the exhaust valve.

[0019] The locking rod is connected to a locking block via a connecting block, and a third spring for resetting is sleeved on the locking rod.

[0020] The cup body is provided with a cup mouth assembly, which includes a concave cup mouth and a convex cup mouth from bottom to top. The concave cup mouth matches a hook. The separation and connection of the concave cup mouth and the hook realizes the opening and closing of the cup lid and the cup body.

[0021] The key positioning block also has a positioning groove that mates with the rotating component, and the positioning groove is integrally connected to the slide rail valley section. The positioning groove is used to limit the position of the key component, so that it can only rotate along the slide rail valley section.

[0022] The upper cup lid is also equipped with a sliding cover for closing the locking hole.

[0023] The key limiting block also has a limiting groove that mates with the rotating component, and the limiting groove is integrally connected to the slide rail valley section. The first mounting plate also has a central magnet to attract the key component, so that the key component is limited when inserted (it can only rotate around the center position and cannot move as a whole). During the insertion process, the bottom of the key is limited by the central magnet, and the sides are limited by the limiting groove, so that it can only rotate within the slide rail valley section.

[0024] This utility model has the following features and significant effects:

[0025] This utility model relates to a key-operated cup lid with a locking structure, which has multiple applications:

[0026] 1. The key assembly is not inserted into the mounting hole, and the sliding cover closes the locking hole, indicating that it is in a closed state.

[0027] 2. When the key assembly is inserted into the bottom of the mounting hole and the locking assembly is not pressed, the locking hole in the key assembly is limited by the locking block, and the key assembly cannot be rotated or moved up and down. The key assembly can be turned into a handle for carrying a cup.

[0028] 3. Insert the key assembly into the bottom of the mounting hole, press the locking assembly, and the locking hole and locking block in the key assembly will separate. The user can rotate the key assembly, and the rotating assembly will match the key limit block. Rotating 90 degrees will push the locking assembly outward, separating the hook from the concave cup opening, thus separating the cup lid and the cup body. After rotation, the locking assembly will reset under the action of the first spring, thus locking the cup lid and the cup body. When rotating, the lower contact will press down on the upper contact, causing the exhaust valve to move down, thus venting the air. The key assembly can be carried at any time, ensuring the safety of drinking water in the cup. It provides convenience in specific situations (when athletes are out or attending important meetings), and in some public places, it can further improve the user's privacy and security.
