Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the connection of the reducing pipes includes two reducing pipes with different outer diameters, when two reducing pipes with different outer diameters need to be connected, the embodiment discloses a reducing pipe connector, which includes two semicircular clamps 1 that are closed together, two sides of an inner ring of each clamp 1 respectively extend inwards along the circumferential direction to form a first snap ring 11 and a second snap ring 12, inner diameters of the first snap ring 11 and the second snap ring 12 respectively fit with a snap groove 21 on the corresponding reducing pipe 2, two ends of each clamp 1 are symmetrically provided with mounting plates 13 that extend outwards, an annular sealing member 3 is embedded in the inner ring of each clamp 1, two sides of the inner ring of the sealing member 3 respectively extend inwards along the circumferential direction to form a first sealing ring 31 and a second sealing ring 32, inner diameters of the first sealing ring 31 and the second sealing ring 32 respectively fit with the outer diameters of the corresponding reducing pipes 2, the first sealing ring 31 and the second sealing ring 32 can effectively seal the two butted reducing pipes, the two clamp hoops 1 are fastened together by a connecting piece (not shown) fixed on the corresponding mounting plate 13.

As shown in fig. 3 and 4, in an embodiment, the inner ring of the clamp 1 is circumferentially provided with a recessed annular groove 14, and the outer ring of the sealing element 3 is circumferentially provided with a protruding ring 34 adapted to the annular groove 14, so that the axial force of the sealing element 3 can be increased, and the sealing effect can be ensured.

The sealing member 3 of this embodiment adopts the silicon rubber material, and the silicon rubber has longe-lived, and the characteristics that elasticity is good can satisfy the sealed requirement to reducing pipe 2.

In order to improve the sealing performance, in an embodiment, the inner diameter of the first sealing ring 31 is smaller than the outer diameter of the corresponding reducing pipe 2, and the inner cavity of the second sealing ring 32 is smaller than the outer diameter of the corresponding reducing pipe 2. When the sealing member 3 is mounted on the outer diameter of the reducing pipe 2, the first sealing ring 31 and the second sealing ring 32 are compressed and contracted by the reducing pipe 2, and the sealing performance of the sealing member 3 on the two butted reducing pipes 2 is improved.

As shown in fig. 3, in an embodiment, the mounting plate 13 of each clamp 1 is provided with a positioning block 132 protruding outward, the positioning block 132 is located on an end surface of the mounting plate 13 facing away from the clamp 1, and a positioning groove 133 adapted to the positioning block 132 is provided on an end surface of the other mounting plate 13 facing away from the clamp 1.
