Description
Technical Field
The invention relates to the technical field of kettles or water cups, in particular to a waterproof prestress structure of a kettle or a water cup.
Background
As shown in fig. 1, a general water bottle or cup mainly includes a cup body 11 and a cover 12, and since the cup body 11 is mainly filled with liquid, when the cover 12 is covered on the cup body 11, a gap is formed between the cover 12 and the cup body 11, which are made of hard material, so as to prevent the liquid from overflowing after the cup body 11 and the cover 12 are covered, a rubber ring 13 is provided between the cover 12 and the cup body 11.
The cup body 11 mainly has a first rotation surface 111 facing the cover body 12, the cover body 12 has a second rotation surface 121 facing the cup body 11, and the rubber ring 13 is installed between the first rotation surface 111 and the second rotation surface 121, when the cover body 12 and the cup body 11 are covered, because the material of the rubber ring 13 has flexibility, the rubber ring 13 is tightly adhered to the first rotation surface 111 and the second rotation surface 121 by the flexibility of the rubber ring 13, and further the cup body 11 and the cover body 12 are sealed, so that the effect of preventing liquid from overflowing is achieved.
As shown in fig. 2 and 3, in the process of screwing the cover 12 and the cup body 11 together, the rubber ring 13 not only receives the vertical pressure from the cup body 11 and the cover 12, but also the rubber ring 13 abuts against the first screwing surface 111 and the second screwing surface 121 respectively, and when the cup body 11 and the cover 12 are screwed together, the cup body 11 and the cover 12 will rotate in a staggered manner, and the rubber ring 13 will further receive the torsion generated when the cup body 11 and the cover 12 are screwed together, so that after the cup body 11 and the cover 12 are completely screwed together, the rubber ring 13 will be in a severely deformed state.
Because the rubber ring 13 still generates serious material distortion even under the normal use state, which causes the defect that the rubber ring 13 is easy to damage, in view of this, it is necessary to solve the problem that the rubber ring 13 is seriously distorted due to the fact that the rubber ring 13 is stressed from different directions.
