Inner wall one end of the inner cone sleeve is equipped with internal thread, and the rest part of inner wall is inner circle frustum, the big end of inner circle frustum
It is adjacent with internal thread, and outside diameter is more than the outer diameter of fire hose, end diameter is equal to the outer diameter of fire hose, inner circle frustum
Cone angle it is equal with the frustum of a cone cone angle that the big end cutting point line in pagoda ring is turned round along axis.
Further, the cone angle of the inner circle frustum is arranged between 2 ° -4 °.
Further, two sections are at least arranged in the pagoda ring.
Further, the connecting tube, outside cone joint are made of aluminum alloy materials.
Further, the inner cone sleeve is made of nonmetallic materials.
The present invention mutually presss from both sides fire hose using inner cone sleeve and the conical surface of frustum inside and outside outside cone joint, to realize that water band connects
The connection of mouth and fire hose has following favorable attributes compared with conventionally employed galvanized wire and hose clamp tighten connection type；
1, simple in structure, easy to operate, without specialized training, easy to learn；
2, stable connection, and connecting elements non-corrosive, it is thus possible to which permanent retention is connected firmly state；
3, it is made of nonmetallic materials in outermost inner cone sleeve, fire hose interconnecting piece can be effectively prevent to be dragged
It draws abrasion or hits the damage generated, thus can play a very good protection to fire hose.
