[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] Reference Figure 1 、 Figure 2A flexible joint structure for rainwater and sewage outlet pipes includes a joint pipe 1, with elastic buffer rings 2 fixedly connected at both ends of the inner wall of the joint pipe 1. The buffer rings 2 are arranged along the circumference of the joint pipe 1. When the outlet pipe and the drainage pipe are inserted into the joint pipe 1, the buffer ring 2 undergoes elastic deformation and hugs the outer surface of the outlet pipe or the drainage pipe to achieve a flexible and sealed connection between the joint pipe 1 and the outlet pipe and the drainage pipe.

[0023] In this embodiment, the buffer ring 2 is made of rubber or silicone material. This design can utilize the elastic force of the buffer ring 2 to play a buffering role. When the connecting pipe 1 and the drainage pipe settle, the buffer ring 2 undergoes elastic deformation and absorbs the force between the connecting pipe 1 and the outlet pipe, thereby reducing the risk of breakage at the connection position between the connecting pipe 1 and the outlet pipe and improving the stability of use.

[0024] Reference Figure 1 、 Figure 2 An elastic part 3 is provided inside each buffer ring 2, and the elastic force direction of the elastic part 3 is set along the radial direction of the buffer ring 2 to ensure the elastic effect of the buffer ring 2, thereby improving the sealing between the buffer ring 2 and the outlet pipe and the drainage pipe.

[0025] Reference Figure 3 、 Figure 4 and Figure 5 The buffer ring 2 has an annular accommodating cavity 4 disposed circumferentially therein. The elastic member 3 is an elastic ring, a plurality of elastic balls, or a plurality of springs, and the elastic ring, elastic ball, or spring is disposed within the accommodating cavity 4. If the elastic member 3 is an elastic ring, the elastic ring is made of spring steel and is disposed circumferentially around the accommodating cavity 4. If the elastic member 3 is an elastic ball, the elastic ball is made of rubber or silicone, and the elastic force of the elastic ball is greater than that of the buffer ring 2. The multiple elastic balls are closely spaced along the circumference of the accommodating cavity 4. If the elastic member 3 is a spring, the multiple elastic balls are closely spaced along the circumference of the accommodating cavity 4.

[0026] Reference Figure 1 、 Figure 2 The ends of the two buffer rings 2 that are away from each other are respectively integrally formed with guide slopes 5, so that the outgoing pipe and the drainage pipe can be smoothly inserted into the joint pipe 1, thereby improving the guiding effect.

[0027] Reference Figure 1 、 Figure 2 A sealing ring 6 is fixedly connected to the center of the inner wall of the joint pipe 1. The sealing ring 6 is arranged along the circumference of the joint pipe 1 and is integrally connected to the two buffer rings 2. At the same time, when the household pipe and the drainage pipe are respectively inserted into the joint pipe 1, the household pipe and the drainage pipe abut against the corresponding side walls of the sealing ring 6 and form a seal, thereby improving the stability of the sealing connection.

[0028] Reference Figure 1 、 Figure 2 The two side walls of the sealing ring 6 are respectively integrally connected with sealing lips 7 along their circumference, and a sealing groove 8 is formed between the sealing lip 7 and the joint pipe 1, and the household pipe or drainage pipe can be fitly inserted into the corresponding sealing groove 8, thereby further improving the sealing stability between the joint pipe 1 and the household pipe and drainage pipe.

[0029] Reference Figure 1 、 Figure 2 The ends of the two sealing lips 7 that are away from each other are respectively integrally formed with a guide surface 9, which has achieved a diversion effect on the sewage, so that the sewage can pass smoothly and ensure the drainage effect.
