Disclose the patent of entitled rubber hose in existing patent such as CN201420125947, the patent use have it is hollow
The inner rubber layer in portion, in the periphery of inner side rubber layer and by weaving the first braiding layer formed by multiple first thread like bodies,
Intermediate rubber layer in the periphery of the first braiding layer, the periphery of intermediate rubber layer and by weave multiple second thread like bodies and shape
Into the second braiding layer, and located at the second braiding layer periphery outer rubber layer, the first braiding layer is with Three Up Three Down
Multiple first thread like bodies that pattern is constituted to the vinylon fiber by being manufactured by dry process carry out braiding, and second compiles
Tissue layer is that multiple second thread like bodies constituted with two times patterns on two to the vinylon fiber by being manufactured by damp process are carried out
Braiding.
But, in prior art and Patent No. CN201420125947 patent, rubber hose is flexible, bending half
Footpath is smaller, but bending angle be more than 90 degree when, the flexible pipe in knee is easily deflated, hinder conveying thing smooth circulation, while rubber
Pipe is yielding, and easy aging, service life is shorter, and cost can be improved by often changing.
