Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1, a cavity communicating the upper end and the lower end is formed in the adapter body 1, the two ends of the cavity are respectively provided with a first connector 2 and a second connector 8 which are respectively used for connecting a drainage tube connector 11 and a flushing bag connector 10, a first switching part and a second switching part are arranged in the cavity, and the first switching part comprises the first connector 2, a sealing ring 4 and an annular sealing step 9 from outside to inside in sequence; the first connecting port 2 is provided with internal threads, the inner diameter of the first connecting port 2 is gradually reduced from the upper end to the lower end, a sealing ring 4 is fixed at the bottom of the first connecting port 2, and a plurality of annular sealing steps 9 extending towards the center are sequentially fixed below the sealing ring 4 from top to bottom; an elastic silica gel sleeve 5 is further connected to the inner side of the first transfer part, the inner diameter and the outer diameter of the elastic silica gel sleeve 5 are gradually reduced from the upper end to the lower end, and the thickness of the elastic silica gel sleeve 5 is uniform; elastic silica gel cover 5 be close to the outer wall of upper end seted up with the external screw thread of 2 looks adaptations of first connecting port, elastic silica gel cover 5 is close to the outer wall top-down of lower extreme fixed cover in proper order and has connect a plurality of sealing sleeve ring 6, and sealing sleeve ring 6's surface and annular seal step 9 are inconsistent forms a plurality of sealing contact surface, adapter body 1 inboard in spherical inner chamber 7 has been seted up to annular seal step 9's below, and the structure of second switching portion is the same with first switching portion and about spherical inner chamber 7 symmetry.
The integrative swing joint in outside both ends of preferred adapter body 1 has block 3, and block 3 and elastic silica gel cover 5's outer end looks adaptation can seal the elastic silica gel cover at both ends when not using, prevents external pollution. In the first transition, the inner diameter of the annular sealing step 9 decreases from top to bottom in succession, while the annular sealing step 9 in the second transition is symmetrical in construction therewith. Thereby adapting to external drain fittings of different diameter sizes. The minimum internal diameter of the first connector 2 is greater than the internal diameter of the uppermost sealing collar 6 to facilitate the installation of the elastomeric silicone sleeve 5 within the cavity.
