[0028] Further as shown in the drawings, Figure 5 Inner lining metal piece 11 includes inner lining metal ring 111, and the inside of one end of rubber tube 1 is covered with inner lining metal ring 111, which can form an inner lining structure at one end of rubber tube 1 close to the pipeline, improve its structural strength, and reduce the probability that the end of rubber tube 1 is extruded and deformed;A plurality of connecting plates 113 are integrally formed on inner lining metal ring 111 by casting process, one end of connecting plate 113 extends into matched pressure covering part 2 and is integrally formed with it, which can form an inner lining in the inside of pressure covering part 2, improve its compression resistance, and can strengthen the firmness of the connection between pressure covering part 2 and the main part of rubber tube 1.

[0029] Secondly, the inner lining metal ring 111 is a double ring structure, and a plurality of inner embedding openings 112 are arranged between the double ring structure. In the manufacturing process of the rubber pipe 1, the rubber material is embedded in the inner embedding openings 112, so that the connection between the inner lining metal ring 111 and the rubber pipe 1 is improved. A plurality of inner embedding holes 114 are drilled on the connecting plate 113, and the rubber material is embedded in the inner embedding holes 114, so that the connecting plate 113 can be more firmly embedded in the pressure covering part 2, and the connection between the pressure covering part 2 and the main body of the rubber pipe 1 is improved, and the probability of cracking of the contact end of the pressure covering part 2 after being extruded is reduced.

[0030] Further in Figure 3 , Figure 5 , the end of the pressure covering part 2 away from the rubber pipe 1 is drilled with a filling groove 21, and a metal gasket 22 is movably inserted in the filling groove 21. After the flange connecting ring 3 is tightly connected with the pipe, the pressure covering part 2 is extruded by a strong force.
