[0034] Please refer to Figure 1-6A socket-type sealing interface for municipal sewage pipes includes: a spigot pipe 1 with a spigot fitting 3 installed on one side; a socket pipe 2 with a spigot fitting 4 at one end of the spigot pipe 1; a first connecting part 5 installed at the end of the spigot pipe 1 near the socket pipe 2; a second connecting part 6 installed at the end of the socket pipe 2 near the spigot pipe 1; arc-shaped grooves 7 on opposite sides of the first connecting part 5 and the second connecting part 6; a sealing gasket 8 between the first connecting part 5 and the second connecting part 6; arc-shaped rings 9 fixedly connected to both sides of the sealing gasket 8; and a clamping mechanism 10 at the connection between the spigot pipe 1 and the socket pipe 2. The first connecting part 5 and the second connecting part 6 cooperate, and the arc-shaped rings 9 cooperate with the arc-shaped grooves 7. Multiple sealing rings 11 are installed on the outer wall of the spigot fitting 3, and multiple sealing grooves 12 are opened on the inner wall of the spigot fitting 4. The sealing rings 11 cooperate with the sealing grooves 12. A rubber ring 13 is installed on the inner wall of the insertion hole 4, and one end of the insertion pipe 3 is fitted with the rubber ring 13. When connecting municipal sewage pipes, first align the insertion pipe 3 of the insertion pipe 1 with the insertion hole 4 of the socket pipe 2. Since the sealing ring 11 on the outer wall of the insertion pipe 3 fits with the sealing groove 12 on the inner wall of the insertion hole 4, during insertion, the sealing ring 11 is embedded in the sealing groove 12, initially forming a sealing barrier to prevent sewage from leaking from the radial gaps in the pipe. At the same time, one end of the insertion pipe 3 is in close contact with the rubber ring 13 on the inner wall of the insertion hole 4. The rubber ring 13, by its own elastic deformation, further fills the gap at the pipe connection, enhancing the radial sealing effect. When the insertion pipe 3 is inserted into place, the first connecting part 5 of the insertion pipe 1 is aligned with the second connecting part 6 of the socket pipe 2. At this time, the arc-shaped rings 9 on both sides of the sealing gasket 8 are embedded in the arc-shaped grooves 7 on the opposite side of the first connecting part 5 and the second connecting part 6. The fit between the arc-shaped rings 9 and the arc-shaped grooves 7 compresses the sealing gasket 8, effectively preventing sewage from leaking from the axial interface of the pipe.

[0035] Please refer to Figure 1 and Figure 2The clamping mechanism 10 includes a lower clamp 101 disposed on the lower side of the spigot pipe 1, an upper clamp 102 disposed on the upper side of the lower clamp 101, and U-shaped frames 103 fixedly connected to both ends of the lower clamp 101 and the upper clamp 102. A connecting rod 104 is disposed between the two U-shaped frames 103 on one side, and a T-shaped rod 105 is rotatably fitted to the inner wall of the U-shaped frame 103 on the other side. A locking nut 106 is threaded onto one end of the T-shaped rod 105. Trapezoidal extrusion grooves 107 are provided on opposite sides of the lower clamp 101 and the upper clamp 102. The lower clamp 101 and the upper clamp 102 cooperate with each other, the two ends of the connecting rod 104 are rotatably fitted with the corresponding U-shaped frames 103, and the trapezoidal extrusion grooves 107 are respectively fitted with the first connecting part 5 and the second connecting part 6. The interface is reinforced using a clamping mechanism 10. The lower clamp 101 is placed under the spigot pipe 1, and the upper clamp 102 is engaged with the lower clamp 101 at the pipe interface. Due to the U-shaped frame 103 structure at both ends of the lower clamp 101 and the upper clamp 102, the two ends of the connecting rod 104 can be rotatably installed between the two U-shaped frames 103 on one side. The T-shaped rod 105, which is rotatably engaged with the inner wall of the U-shaped frame 103 on the other side, passes through the corresponding U-shaped frame 103. By tightening the locking nut 106, the lower clamp 101 and the upper clamp 102 gradually approach and clamp the pipe interface. During the process of the lower clamp 101 and the upper clamp 102 approaching each other, the trapezoidal extrusion groove 107 on their opposite sides extrudes the first connecting part 5 and the second connecting part 6 respectively, so that the first connecting part 5 and the second connecting part 6 further press the sealing gasket 8, thereby enhancing the connection stability between the spigot pipe 1 and the socket pipe 2 and preventing the interface from loosening under sewage pressure or external force.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
