detailed description:

In order to clearly illustrate the technical features of this solution, the utility model will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

As shown in Figure 1-2, a connection device between a hollow-wall winding pipe 1 and a plastic well 4 includes a hollow double-wall corrugated pipe 2 connected to the hollow-wall winding pipe 1, a hollow-wall winding pipe 1 and a hollow double-wall corrugated pipe. One end of the tube 2 is connected through a heat shrinkable sleeve 3, and the other end of the hollow double-wall corrugated pipe 2 is connected with the plastic well 4 through a connecting mechanism. The side is provided with an annular groove 6, and an anti-skid ring 7 concentric with the rubber ring 5 is arranged on the inner edge of the annular groove 6, and a fastening ring 8 is arranged on the outer edge of the annular groove 6, and the thickness of the fastening ring 8 is made close to the rubber ring. The inner end of 5 gradually increases toward the outer end, and a fastening nut 9 is provided on the outer threaded mounting sleeve of the fastening ring 8 .

Anti-slip particles are provided on the inner surface of the anti-slip ring 7, and anti-slip threads are provided on the inner side of the fastening ring 8.

When connecting, the hollow-wall winding tube 1 is first connected with the hollow double-wall corrugated tube 2 through the heat-shrinkable sleeve 3, and then the other end of the hollow double-wall corrugated tube 2 is inserted into the rubber ring 5 until it extends into the anti-skid ring 7 , the anti-skid ring 7 is attached to the outer surface of the hollow double-wall corrugated pipe 2, and then the connection port end of the plastic well 4 is inserted into the annular groove 6, and the fastening ring 8 is set on the outside of the connection port, passing through the plastic well 4 side Turning the fastening nut 9 can tighten the fastening ring 8 inwards, thereby pressing down the connection port of the plastic well 4 to achieve the connection between the hollow-wall winding pipe 1 and the plastic well 4 .

The connection device between the hollow wall winding pipe and the plastic well of the utility model adopts the hollow double-wall corrugated pipe 2 as an intermediate mechanism for connection, the connection method is simple and fast, and there is no gap between the hollow double-wall corrugated pipe 2 and the hollow wall winding pipe 1 The gap is tightly connected after the connection, and the stability is good. The connection between the hollow double-wall corrugated pipe 2 and the plastic well 4 is connected by a connection mechanism. After the connection, the appearance is beautiful, the sealing is good, and there is no risk of water leakage.
