Description

Abnormal sound prevention cup cover

Technical Field

The utility model relates to a bowl cover, especially a prevent abnormal sound bowl cover.

Background

The existing cup cover has a structure with good sealing performance, for example, in the 'heat preservation cup cover' with the application number of 201721471962.0, a sealing element 4 is sleeved at the lower end of a lower cover, when the cup cover is screwed down, the sealing element 4 and the inner wall of a cup body form tight fit, the sealing effect is good, and the heat preservation performance is also improved due to the good sealing effect.

However, the cup cover with the structure has a defect that: when the cup cover is screwed down or loosened, the sealing element rotates along with the cup cover, so that large abnormal sound can be generated between the sealing element in tight fit and the inner wall of the cup body.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent abnormal sound bowl cover, under the prerequisite of guaranteeing not to influence sealed effect, eliminate the abnormal sound of bowl cover when screwing up or loosening, avoid producing the noise that influences the sense of hearing.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a prevent abnormal sound bowl cover, includes the bowl cover shell, sets up the lid stopper in the bowl cover shell, the lid stopper comprises at the bottom of cylinder rampart and cask shape end, the upper end and the caping of cylinder rampart concretize, the outside of cylinder rampart be equipped with the rim of a cup spiro union's of cup screw thread, the lower part of cylinder rampart through relative pivoted buckle structure with cask shape end is connected, is equipped with the annular under cask shape end outside the tip, this annular inside callipers be equipped with the sealing member of the binding off inner wall tight fit of cup.

But relative pivoted buckle structure includes, sets up at the inboard bead of cylinder rampart lower part annular, sets up at the outside flat ring that extends in cask shape end bottom middle part, sets up stand ring on the flat ring, the top outside of stand ring is equipped with annular outside bead, the inboard bead of annular is located below annular outside bead, and the lower extreme of cylinder rampart is located the higher authority of flat ring, and when screwing up the bowl cover shell downwards, the flat ring of downward conflict of the lower extreme of cylinder rampart, sealing member and binding off inner wall tight fit, when upwards screwing up the bowl cover shell, the inboard bead of annular upwards conflicts annular outside bead, the sealing member breaks away from with the binding off inner wall.

The cup cover shell, the cylindrical annular wall and the annular inner side convex edge are of an integrated structure, and the annular groove, the flat ring, the vertical ring and the annular outer side convex edge are of an integrated structure.

Compared with the prior art, the beneficial effects of the utility model are that: by adopting the technical scheme, the sealing element is tightly matched with the closing-in inner wall of the cup body, a certain resistance is arranged between the sealing element and the closing-in inner wall of the cup body, the lower part of the cylindrical annular wall is connected with the cylindrical end bottom through a relatively rotatable buckle structure, the cylindrical annular wall is downwards pressed against the cylindrical end bottom through the relatively rotatable buckle structure when the cup cover shell is screwed downwards, the sealing element only moves downwards along a smaller path at a lower speed (relative to the situation that the sealing element rotates along with the cup cover), no large abnormal sound is generated between the sealing element and the closing-in inner wall, noise influencing the sense of hearing is not generated at all, when the cup cover shell is screwed upwards, the cylindrical annular wall upwards pulls up the cylindrical end bottom through the relatively rotatable buckle structure, the sealing element is separated from the closing-in inner wall, the sealing element only moves upwards along a smaller path at a lower speed (relative to the situation that the sealing element rotates along with the cup cover), the sealing element and the inner wall of the closing-in do not generate large abnormal sound, and at least noise influencing the hearing is not generated.
