Rubber sealing ring

Abstract

The invention relates to the field of sealing rings, in particular to a rubber sealing ring which comprises an upper ring and a lower ring integrally connected with the bottom of the upper ring, through holes are formed in the upper ring and the lower ring in a penetrating mode, and the two through holes are integrally formed and are the same in diameter; the top of the upper ring is provided with a pressing mechanism, and the outer wall of the lower ring is connected with a fastening mechanism. The outer sealing ring tightly abuts against the inner wall of the heat preservation barrel cover, and the outer sealing ring and the inner wall of the heat preservation barrel cover are fully sealed, so that good sealing performance is achieved between the upper ring and the heat preservation barrel cover, water in the heat preservation barrel is not prone to entering the space between the sealing ring and the heat preservation barrel cover, residual water between the sealing ring and the heat preservation barrel cover is reduced, and the service life of the heat preservation barrel is prolonged. And therefore, the bacteria breeding environment is reduced, and the heat preservation barrel cover is safer and more sanitary in use.

Description

technical field [0001] The invention relates to the field of sealing rings, in particular to a rubber sealing ring. Background technique [0002] The rubber sealing ring is an annular cover composed of one or several parts, which is used in the space between the two objects connected to each other to improve the tightness of the connection between the objects, so that after the two objects are connected, the connection will not occur. leakage. [0003] For the sealing ring used in the larger thermal insulation barrel, when the commonly used thermal insulation barrel cover is connected with the thermal insulation barrel body, the inside of the thermal insulation barrel cover is sealed with a rubber seal, so that after the thermal insulation barrel cover is connected with the thermal insulation barrel body, the thermal insulation barrel The water in the body does not leak out. After the sealing ring in the insulation barrel is heated by the hot water in the insulation barrel...

AI Technical Summary

Problems solved by technology

After the sealing ring in the heat preservation barrel is heated by the hot water in the heat preservation barrel, it is prone to thermal expansion and contraction, and then it is separated from the heat preservation barrel cover, which affects the user's experience and makes the inner sealing ring easy to lose. As a result, the insulation barrel cover cannot effectively seal the insulation barrel body

The sealing ring is bonded to the lid of the insulation barrel with glue. The glue has a smell, which affects the taste of drinking water, and the safety of the glue cannot be guaranteed, which may cause harm to the body.

The sealing performance between the sealing ring and the lid of the insulation bucket is not high, and the inside is easy to enter water, and the long-term stay of the internal water stains will easily breed bacteria and affect the normal use of the insulation bucket
