[0002] Municipal drainage pipe is an important part of urban infrastructure, used to collect and discharge rainwater, domestic sewage and industrial wastewater, to ensure the efficient operation of urban drainage system, prevent waterlogging and environmental pollution. Municipal drainage pipe is usually composed of multiple pipes, connecting these pipes can form a continuous system to ensure smooth water flow.

[0003] However, when connecting two drainage pipes together through a joint, if the sealing effect at the connection of the drainage pipes is not good, water leakage may occur at the connection, and water may seep out of the pipes, especially in sewage pipes, water leakage may contaminate soil and groundwater. SUMMARY

[0004] The utility model aims to solve the above problems and provides a kind of municipal drainage pipe, when the end of the joint is inserted into the joint by the fixed plate, the insert block can connect the two joints together, and the sealing gasket fixed on the joint is in contact with the drainage pipe, which is beneficial to improve the sealing performance of the connection part of the two drainage pipes.

[0005] The utility model realizes the above-mentioned purpose through the following technical scheme, a kind of municipal drainage pipe, including drainage pipe, two the splicing mechanism is installed in the drainage pipe, the splicing mechanism includes joint and sealing gasket, the sealing gasket is connected with the joint, the joint is fixedly connected with the sealing gasket, the insert block is connected with the joint, the insert block is fixedly connected with the fixed plate, two groups of ball bearings are rotatably installed in the insert block.

[0006] Preferably, a plurality of grooves are equidistantly arranged in the drainage pipe, and the sealing gaskets are installed in the grooves.

[0007] Preferably, the part of the sealing gasket in contact with the joint is provided with an arc surface structure, and the part of the sealing gasket in contact with the drainage pipe is provided with an inclined surface structure.

[0008] Preferably, the joint and the sealing gasket are mutually engaged, and the joint is provided with an arc surface structure.

[0009] Preferably, the joint is provided with a slot at both ends, and the inner wall of the joint is bonded with a gasket.

[0010] Preferably, the gasket is provided with a right-angled triangle structure, and the gasket is located in the slot.

[0011] Preferably, the insert block is installed in the slot, and the ball bearings are rotatably connected with the joint.

[0012] Preferably, the plug connects the two ends of the connector, and the part of the plug that contacts the gasket has an inclined structure.

[0013] The beneficial effects of this utility model are as follows: One connector is placed on the ground, and then two drain pipes are moved into the connector. Since several grooves are evenly spaced inside the drain pipes, when the sealing gasket adhered to the connector engages with the grooves, it can contact the side wall of the drain pipe, thus initially limiting the position of the two drain pipes. Next, another connector is placed on the bottom connector, with the ends of the two connectors contacting each other. Holding the fixing plate causes the insert block to engage with the inner wall of the two connectors. Since the insert block contains two sets of ball bearings, tapping the fixing plate with a tool allows the insert block to slide into the connector. The rolling ball bearings contact the connector, reducing friction between the insert block and the connector, thus facilitating the fixing of the two connectors with the insert block. This also ensures a tight fit between the sealing gasket and the drain pipe, improving the sealing performance of the drain pipe connection. Attached Figure Description

[0024] As a technical optimization scheme of the present utility model, a plurality of grooves 3 are equidistantly arranged in the drainage pipe 1, and the sealing gasket 203 is clamped and installed at the groove 3 part, so that the sealing gasket 203 can be clamped together with the side wall of the drainage pipe 1 when clamped to the groove 3 part.

[0025] As a technical optimization scheme of the present utility model, the part of the sealing gasket 203 in contact with the joint 201 is provided in an arc surface structure, and the part of the sealing gasket 203 clamped with the drainage pipe 1 is provided in an inclined surface structure, so that the sealing gasket 203 can seal the connection part of the two drainage pipes 1 when clamped with the drainage pipe 1.

[0026] As a technical optimization scheme of the present utility model, the two joints 201 and the sealing gasket 203 are clamped and connected to each other, the joint 201 is provided in an arc surface structure, and the joint 201 can clamp the sealing gasket 203 together with the side wall of the drainage pipe 1 when connecting the two drainage pipes 1.

[0027] As a technical optimization scheme of the present utility model, the two ends of the joint 201 are provided with insertion grooves 5, and the inner wall of the joint 201 is bonded with a gasket 4, so that the two joints 201 can be quickly connected when the insertion block 204 is clamped to the insertion groove 5 part.

[0028] As a technical optimization scheme of the present utility model, the gasket 4 is provided in a right-angled triangle structure, and the gasket 4 is located in the insertion groove 5, so that the sealing property between the insertion block 204 and the joint 201 can be improved when the gasket 4 is in contact with the insertion block 204.
