Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a cup cover capable of being opened and closed by pressing and a cup thereof. Background Art

[0002] The current thermos cup lid is equipped with a quick-release cup lid that can be opened and closed. The quick-release cup lid is a cup component that allows users to quickly open and close it, and usually has a simple operating mechanism. The design of the quick-release cup lid makes opening and closing very simple and quick, and is especially suitable for use in busy situations or situations where quick drinking water is needed. In order to ensure that the liquid does not leak, the quick-release cup lid often has excellent sealing performance, and can effectively prevent liquid spillage even when shaking or moving. Since the structure of the quick-release cup lid may be relatively complex, frequent use or improper operation may cause certain parts to wear or loosen, affecting the service life. In addition, if the quick-release mechanism is not designed properly, there may be a risk of accidental opening, especially when carrying or moving the cup, which may cause safety issues such as liquid splashing or scalding.

[0003] For example, utility model patent CN220655330U discloses a magnetic push-to-release quick-release cup cover, comprising a cover body, which can be installed on the cup mouth of the cup body, a sliding body installed in the cover body for sliding up and down movement, an elastic sealing sleeve sleeved between the cover body and the lower end of the sliding body, the sliding body and the cover body approach each other to squeeze the elastic sealing sleeve to deform, a magnetic locking device matched with the sliding body is provided on the cup cover, the sliding body moves to the highest point and is locked in the position by the attraction of the magnetic locking device, thereby maintaining the deformation of the elastic sealing sleeve; applying external force to press the sliding body downward, Under the action of external force, the sliding body is separated from the position lock of the magnetic locking device, and the elastic sealing sleeve returns to its original shape. At this time, the cup lid can be removed from the cup mouth. The utility model is also provided with an air pressure balancing component that cooperates with the magnetic locking device. When the sliding body is pressed downward, the air pressure balancing component is first opened to balance the air pressure inside and outside the cup body, making it easier and more labor-saving to press the sliding body and remove the cup lid. However, when the cup lid structure is carried and used, it is easy to cause the pressing structure to be pressed downward, which may cause the cup lid to be opened accidentally, and there is a risk of the cup body falling and scalding. Utility Model Content

[0008] Furthermore, the upper end of the rebound column is fixedly connected to a limiting base having a diameter larger than that of its body, and one end of the elastic limiting block is elastically connected to the side wall of the vertical portion of the upper surface of the limiting base through a limiting spring.

[0009] Furthermore, a rebound spring is fixed to the outer side wall of the rebound column, and the lower end of the rebound spring is supported on the bottom part of the cup cover.

[0010] Furthermore, the bottom portion of the cup cover is fixedly connected to the body via a barb structure, and the rebound column passes through the hollow column of the bottom portion of the cup cover, and the lower end of the rebound spring is supported on the upper end of the hollow column.

[0011] Furthermore, a sleeve structure is fixed to the upper end of the rebound column outside the rebound spring, and a left-right symmetrical hinge structure is arranged on the outer side wall of the bottom of the sleeve structure. The inner end of each stopper is rotatably connected to the hinge structure through a rotating shaft.

[0012] Furthermore, guide plates are respectively arranged on both sides of the limit spring, one end of the guide plate is fixedly connected to the side wall of the vertical part of the upper surface of the limit base, and the other end of the guide plate is located in the guide groove arranged at the end of the elastic limit block.

[0014] A cup comprises the above cup cover, wherein the top opening of the cup body is provided with an inwardly protruding annular retaining ring structure, so that the outer end of each retaining block is closely attached to the lower edge of the annular retaining ring structure after the cup cover is buckled.

[0015] When the utility model is used, if the cup cover is taken off, the elastic limit block is pushed to compress the limit spring, and the limit protrusion is separated from the edge of the upper surface of the cup cover, so that it is easy to press the rebound column downward, and the rebound column is pressed downward to compress the rebound spring, and the rebound column drives the sleeve structure to move downward, thereby driving the inner ends of the blocks on both sides of the sleeve structure downward and rotating until the outer ends of the blocks are retracted from the outer side of the cup cover, that is, the outer ends of the blocks are separated from the lower edge of the annular retaining ring structure, so that the cup cover is smoothly removed from the cup body, and when buckled, the rebound column is released to make the outer end of each block close to the lower edge of the annular retaining ring structure;

[0016] The cup cover of the utility model is not only convenient for quick buckling and opening, but also provided with an elastic limit block which operates perpendicularly to the pressing direction, that is, a limit protrusion is provided at one end of the elastic limit block which is supported on the edge of the upper surface of the cup cover, forming a press-locking structure for the rebound column. Only by pushing and unlocking the elastic limit block first can the rebound column be further pressed, effectively avoiding the cup cover from being opened by mistake when carrying, and making the cup cover more firmly buckled and less likely to fall off.
