Embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment further instruction the technical solution of the utility model：
Embodiment 1
A kind of plastic pipe sealing and connecting device as shown in Figures 1 to 3, by inner tube 2, outer tube 3, internal layer rubber sealing boot 4,
Outer layer rubber sealing shroud 5, fastener 6, fastening kit 7, triangle track 8 and bolt 9 form, and the connector main function is to two
Individual plastic pipe is tightly connected, while plastic pipe interface is protected, and is prevented during sealed extruded so that tubing breaks
Split.The connected mode of the connector is used as double hose connected mode.Connector is divided into two according to the function of the connector
Point, respectively protect part and hermetic unit.
In the interlayer that two plastic pipes 1 are plugged on inner tube 2 and outer tube 3 is formed, its structure is as shown in Fig. 2 two outer
Pipe 3 is fixedly welded on the sandwich that inner tube both ends form sealing, and inner tube 2 is siphunculus, the liquid gas for plastic pipe transmission
