[0002] In order to transport materials such as tap water, electricity, signal data, etc., municipal engineering projects often choose to dig underground and lay concrete or plastic pipes. If the connection distance is long, it is necessary to splice several unconnected pipes, but external vibrations and underground humid water vapor will inevitably invade the interior of the pipes, so it is necessary to use a leak-proof joint device. However, most of these structures are generally unified as a whole, which is quite laborious to install and lacks suppression strength. The internal pipes are inevitably loose, and there are many inconveniences during disassembly and maintenance.

[0003] Now, a novel water-leakage-proof interlocking structure at the connection of municipal pipelines is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a water-leakage-proof interlocking structure for a municipal pipeline connection to solve the problem of inconvenient structural installation proposed in the above-mentioned background technology.

[0014] (1) By welding a circular ring on one side of the casing, the threaded rod movably connected between the positioning blocks can rotate in situ. When the guiding casing is retracted toward the outside of the pipe, it can be closed by means of the circular ring with the meshing groove. Under the lubrication of the ball bearing, the dividing block at the center enters the groove. Then, the positioning blocks are fixed to the upper and lower surfaces of the casings on both sides by angle steel to lock them. The device can be quickly installed.

Inner inserts are respectively welded on the symmetrical fixing blocks at both ends, and the sleeve is movably mounted between the inner inserts. The spacing between the two can be changed according to the diameter of the pipe to be fixed, and then they are fixed with bolts. The frosted pipe pad on the inner wall compresses its own thickness under the pressure of the sponge block and firmly locks the pipes on both sides. Under the opposite adsorption and adhesion of the suction cups on the inner side of the fixing block, the internal pipe is locked from the slot. BRIEF DESCRIPTION OF THE DRAWINGS
