1. A dual sealing ring connector comprising:
a first resilient sealing ring;
a second resilient sealing ring partially embedded in the first resilient sealing ring;
wherein:
the dual sealing ring connector comprises a holding portion and an inserting portion;
the inserting portion is shaped to correspond to the holding portion and embedded into the holding portion;
the inserting portion comprises a joint head, a joint rod, and locking tabs;
the joint rod extends in an extension direction, the extension direction being at least one of a radial direction, an axial direction, or a circumferential direction;
the joint head is arranged at an end of the joint rod and has a shape that is mirror-image symmetrical along an axis of symmetry of the joint rod;
the locking tabs are arranged on both sides of the joint rod and are spaced apart from the joint rod by a distance;
the locking tabs extend in a same direction as the extension direction of the joint rod, and a length of the locking tabs in the extension direction is less than ⅔ of a sum of lengths of the joint head and the joint rod in the extension direction of the joint rod;
the locking tabs comprise a raised portion having an extension direction extending toward the joint rod, and an angle between the extension direction of the locking tabs and the extension direction of the joint rod is 5-35 degrees, such that a spacer sleeve configuration is formed between a portion of the holding portion corresponding to the joint rod and a portion of the holding portion corresponding to the locking tabs; and
the spacer sleeve configuration has at least one protruding portion comprising a resiliently bending and deforming portion with a radius of curvature of 1-4 mm such that, in an event that the inserting portion is inserted into the holding portion (10), the protruding portion squeezes the spacer sleeve configuration in order to resiliently deform the spacer sleeve configuration against the joint rod and the joint head.
