Description

Technical Field

[0001] The utility model relates to a cup cover with an upper end that can be opened and closed by pressing, and belongs to the technical field of thermos cups. Background Art

[0002] Cups are essential items in people's daily lives. They can be categorized into various types based on their purpose, such as water cups, coffee cups, hot drink cups, and thermos cups. Taking thermos cups as an example, thermos cups are generally made of materials such as ceramic, stainless steel, or titanium alloy. They feature a vacuum layer inside the cup body and a sealed lid on top. This vacuum layer insulates the water or other liquids contained within the container from the outside world, achieving the purpose of heat preservation or cooling. The internal structure of a thermos cup typically consists of multiple layers. The vacuum layer is used to prevent heat conduction, and the outer wall of the vacuum layer is plated with silver to prevent heat radiation. A thermos cup typically includes a cup liner, an outer shell, and a lid.

[0003] Conventional cup lids typically open by securing the lid to the cup body via a threaded connection, which offers a simple structure and reliable connection. However, this threaded connection requires the user to use both hands to remove the lid, which can be inconvenient in some situations. Furthermore, the user must repeatedly tighten or loosen the lid before and after each use, significantly reducing closing and opening efficiency. Utility Model Content

[0004] The utility model proposes a method of unlocking the cup lid and the cup body by pressing the upper pressing component. When the cup lid and the cup body are tightly closed, the upper pressing component is returned to its original position by the return piece, thereby locking the cup body and the cup lid. The upper pressing component can press the upper end of the cup lid to open and close for exhaust during the downward movement, thereby solving the problems existing in the prior art.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A cup lid that opens and closes by pressing at the upper end comprises a cup lid, the lower end of which is connected to a cup body; the cup lid comprises an outer wall of the cup lid, a first mounting plate installed inside the cup lid, a second mounting plate connected to the first mounting plate, and a locking assembly; a limiting groove for installing the locking assembly is formed between the cup lid and the first mounting plate, and the locking assembly comprises a vertical member, a horizontal member, and an oblique member connected in sequence, the vertical member is located in the limiting groove, and the vertical member is equipped with a hook that is separated from or closed to the cup body; the separation of the hook and the cup body depends on the distance range of the hook's outward movement.

[0007] An upper pressing assembly is installed at the upper end of the cup cover, and the pressing assembly includes a central column, a pressing front end installed at the upper end of the central column, a pressing middle end, and a pressing expansion end that cooperates with the oblique member to drive the locking assembly to move outward during the downward movement of the upper pressing assembly, causing the hook and the cup body to separate or close. The pressing front end passes through the cup cover, the central column passes through the first mounting plate, and the second mounting plate is fixed by a fastener;

[0008] A locking block is installed between the first mounting plate and the second mounting plate. The locking block is provided with a mounting hole. The central column passes through the mounting hole and is locked or unlocked by the locking block.

[0009] One end of the locking block is connected to a first spring, and the other opposite end is provided with an inclined surface. One end of the first spring abuts against the first mounting plate or the second mounting plate.

[0010] A return piece is provided on the outer side of the second mounting plate, which contacts the cup body and is driven to move upward by the cup body. The return piece abuts against the inclined surface and drives the locking block to move rightward, thereby unlocking the upper pressing assembly.

[0011] The outer contour size of the pressing front end is smaller than the outer contour size of the pressing middle end, and the outer contour size of the pressing middle end is smaller than the outer contour size of the pressing enlarged end.

[0012] The pressing front end, the pressing middle end and the pressing expansion end are mounted on the upper end of the center column.

[0013] A third spring is installed on one side of the locking assembly, and the other side opposite to the third spring is installed on the outer wall of the cup cover or the first mounting plate.

[0014] In one embodiment, a connecting column is installed on the outer wall of the cup cover, a supporting column is installed on one side of the oblique member, and the supporting column and the connecting column sleeve are provided with a third spring that passes through the vertical member.

[0015] In one embodiment, a connecting column is mounted on the first mounting plate, a supporting column is mounted on one side of the oblique member, and a third spring is provided on the connecting column and the supporting column sleeve.

[0016] 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, and the concave cup mouth matches the hook. The separation and connection of the concave cup mouth and the hook realize the opening and closing of the cup cover and the cup body.

[0017] The utility model has the following characteristics and significant effects:

[0018] The utility model relates to a cup lid that opens and closes by pressing the upper end. When the user presses the upper pressing component downward, the pressing enlarged end moves downward to drive the oblique part to move outward to realize the opening and closing of the cup lid and the cup body. When pressed to the bottom, the limiting notch of the central column is locked by the locking block, and the hook is always in the open state.

[0019] When the cup body and the cup lid are closed tightly, the hook is always in the open state, so the cup body can extend upward, the cup body contacts the return piece, driving the return piece upward, and the return piece drives the locking block to the right. The limit notch is unlocked, the locking assembly moves inward (under the action of the third spring), and the center column moves upward to realize the return of the upper pressing assembly.

[0020] The entire structure realizes the opening of the cup lid through the upper pressing component, and the cup body and the cup lid are tightened to realize the return of the upper pressing component to close the cup body and the cup lid. The upper pressing component realizes exhaust at the same time during the downward movement (the center column moves downward, opening the vents of the cup lid and the cup body).
