In order to achieve the above purpose, the present utility model provides the following technical solutions: the rubber sealing piece of the water supply and drainage pipeline comprises a rubber ring and an inner groove, wherein the inner groove is circumferentially arranged in the rubber ring; the inner part of the inner groove is surrounded by a first rubber strip and positioned in the middle of the inner groove, the first rubber strip is clamped in an arc groove formed in the inner groove, and the inner grooves of the inner ring and the outer ring of the first rubber strip are surrounded by a second rubber strip; the top and the below surface of rubber circle all encircle and are provided with the sand grip, and the top and the below of rubber circle all are provided with three rings sand grips.

Through adopting above-mentioned technical scheme, in arranging the rubber circle in the inside cell body that water supply and drainage pipeline connects, connect the back and paste tightly and realize sealed effect between two joints to owing to the setting of inside groove and inside first rubber strip and second rubber strip, also can have good elasticity and deformation effect when winter, ensure to paste tightly between the joint under the effect of sand grip and guarantee good sealed effect.

Optionally, the cross-sectional diameter of the first rubber strip is larger than the cross-sectional diameter of the second rubber strip, and the first rubber strip is in abutting contact with the second rubber strip.

By adopting the technical scheme, the first rubber strip and the second rubber strip are tightly abutted, so that the rubber ring has a certain shape while good elasticity is ensured.

Optionally, two inner clamping grooves are formed in the inner side surface of the rubber ring, and connecting lines of the two inner clamping grooves pass through the circle center of the rubber ring.

Through adopting above-mentioned technical scheme, when the rubber circle is blocked in the cell body of joint and can't take out, can prie it out from interior draw-in groove with the help of the instrument.

Optionally, two outer clamping grooves are formed in the outer side surface of the rubber ring, and connecting lines of the two outer clamping grooves pass through the circle center of the rubber ring.

By adopting the technical scheme, when the rubber ring is clamped in the groove body of the connector and cannot be taken out, the rubber ring can be pried out of the outer clamping groove by means of a tool.

Optionally, the surface connection of sand grip and rubber circle is overall structure, and the distance is equal between the adjacent sand grip.

Through adopting above-mentioned technical scheme, the multiturn sand grip that the distance equals the setting can realize better sealed conflict effect.

Compared with the prior art, the beneficial effects of the technical scheme are as follows:

1. according to the technical scheme, the annular first rubber strip and the annular second rubber strip are arranged in the inner groove of the rubber ring, so that the rubber ring is good in elasticity and deformable, the rubber ring is weakened in winter, the rubber ring is good in elasticity, the protruding strips on the two side surfaces of the rubber ring are matched, the good sealing contact effect is always achieved between the rubber ring and the inner wall of the joint during use, and the good sealing effect is further maintained.

2. According to the technical scheme, the outer clamping groove and the inner clamping groove which do not affect the sealing effect are respectively formed in the inner ring surface and the outer ring surface of the rubber ring, and when the rubber ring is deformed and abutted against the joint inner groove body to be inconvenient to disassemble, the tool can be conveniently utilized to pry the rubber ring from the outer clamping groove or the inner groove.
