[0003] Sealing conversion joints are mainly used to connect pipes in different directions to ensure smooth fluid conversion of direction and flow. To facilitate the connection between other connecting pipes and the conversion joint, a sealing conversion joint for drainage pipes has been designed. This conversion joint, through the use of double-layer connecting pipes and connecting joints, allows the connecting pipe fixed in the inner cavity of the double-layer connecting pipe to be quickly installed or removed from the inner cavity of the connecting joint with the cooperation of ball bearings and limiting annular grooves. This makes it easier to install or remove the connecting pipe in the inner cavity of the connecting joint, thus facilitating the connection between other connecting pipes and the conversion joint.

[0023] In the following description, embodiments of the drainage pipe sealing conversion joint of the present invention will be described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Figure 1-5 This invention illustrates a drainage pipe sealing adapter according to an embodiment of the present invention, comprising: three connecting joints 2 communicating with the surface of a drainage pipe 1; a movable pipe 3 slidably connected to the surface of the connecting joint 2, a pressure ring 4 fixedly connected to the top end of the movable pipe 3; multiple circular holes opened at the top end of the surface of the connecting joint 2, with ball bearings 5 ​​rollingly connected to the inner cavity of the circular holes; a support ring 6 fixedly connected to the surface of the connecting joint 2, with a spring 7 welded between the top end of the support ring 6 and the bottom of the pressure ring 4; a double-layer connecting pipe 8 slidably connected to the inner cavity of the connecting joint 2, with a limiting annular groove 9 opened on the surface of the bottom end of the double-layer connecting pipe 8, and the surface of the ball bearings 5 ​​rollingly connected to the inner cavity of the limiting annular groove 9. The inner cavity of the spring 7 is slidably connected to the surface of the connecting joint 2. The top of the connecting joint 2 is provided with a positioning groove 10, and a sealing gasket 11 is fitted on the top of the connecting joint 2. The sealing gasket 11 is located between the top of the connecting joint 2 and the bottom of the surface of the double-layer connecting pipe 8. A sealing rubber ring 12 is fixedly connected to the bottom of the sealing gasket 11. The surface of the sealing rubber ring 12 is fitted into the inner cavity of the positioning groove 10. Through the cooperation of the positioning groove 10 and the sealing rubber ring 12, the connection between the double-layer connecting pipe 8 and the connecting joint 2 can achieve a better sealing effect, and can better prevent liquid from leaking from the connection between the connecting joint 2 and the double-layer connecting pipe 8.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates a drainage pipe sealing adapter according to an embodiment of the present invention, comprising: three connecting joints 2 communicating with the surface of a drainage pipe 1; a movable pipe 3 slidably connected to the surface of the connecting joint 2, a pressure ring 4 fixedly connected to the top end of the movable pipe 3; multiple circular holes formed at the top end of the surface of the connecting joint 2, with ball bearings 5 ​​slidably connected to the inner cavity of the circular holes; a support ring 6 fixedly connected to the surface of the connecting joint 2, with a spring 7 welded between the top end of the support ring 6 and the bottom of the pressure ring 4; and a double-layer connecting pipe 8 slidably connected to the inner cavity of the connecting joint 2, with a limiting annular groove formed on the surface of the bottom end of the double-layer connecting pipe 8. 9. A limiting ring 13 is fixedly connected to the bottom end of the movable tube 3. The limiting ring 13 is located below the support ring 6. By setting the limiting ring 13, the movable tube 3 can be prevented from slipping off the surface of the connecting joint 2 due to the elastic force of the spring 7 during the sliding process of the movable tube 3 on the surface of the connecting joint 2. This makes the movable tube 3 safer when sliding on the surface of the connecting joint 2. A water-proof ring 14 is fixedly connected to the inner cavity of the connecting joint 2. The bottom end of the double-layer connecting tube 8 is connected to the inner cavity of the water-proof ring 14. A water-blocking pad ring 15 is fixedly connected to the inner cavity of the double-layer connecting tube 8. Anti-slip texture 16 is opened on the surface of the movable tube 3.

[0028] Working principle: When using this invention, the user fixes the connecting tube into the inner cavity of the double-layer connecting tube 8. At this time, the water-blocking ring 15 seals and protects the bottom end of the connecting tube from the inner wall of the double-layer connecting tube 8. Then, the movable tube 3 is pulled and slid on the surface of the connecting joint 2, thereby releasing the pressure ring 4 from pressing and restricting the ball 5. Subsequently, the double-layer connecting tube 8 is inserted into the inner cavity of the connecting joint 2, and the bottom end of the double-layer connecting tube 8 abuts against the surface of the water-blocking ring 14. At this time, the pressure ring 4 is released, and the movable tube 3 slides again under the rebound of the spring 7. This causes the pressure ring 4 to reset, thereby pressing the pressure ring 4 back onto the surface of the ball 5 and causing the ball 5 to roll into the inner cavity of the limiting annular groove 9. This fixes the double-layer connecting pipe 8 in the inner cavity of the connecting joint 2. At the same time, the sealing effect of the sealing gasket ring 11 and the sealing rubber ring 12 can prevent liquid from flowing out of the connection between the double-layer connecting pipe 8 and the connecting joint 2, thus completing the connection between the connecting pipe and the connecting joint 2. This allows the connecting pipe to be installed or removed more easily in the inner cavity of the connecting joint 2, thereby facilitating the connection between other connecting pipes and conversion joints.

[0029] In summary, this drainage pipe sealing adapter, by loosening the pressure ring 4, allows the pressure ring 4 to re-press onto the surface of the ball bearing 5 under the rebound of the spring 7, and the double-layer connecting pipe 8 is fixed in the inner cavity of the connecting joint 2 under the action of the limiting annular groove 9, thereby completing the connection between the connecting pipe and the connecting joint 2. This allows the connecting pipe to be installed or removed more easily in the inner cavity of the connecting joint 2, thus facilitating the connection between other connecting pipes and the adapter.
