In view of this, the purpose of this utility model provides a kind of Drop-proof leakage proof hose coupling, and it can guarantee firm and reliable connection between flexible pipe and hose coupling, and water, wet goods seepage can not take place good seal, avoid the wasting of resources.
The utility model Drop-proof leakage proof hose coupling, comprise the outside thread pipeline section that is used for the taper pipeline section that links to each other with flexible pipe and is arranged on the big end of taper pipeline section, described taper pipeline section and outside thread pipeline section overcoat have flexible pipe clamping sleeve assembly, described flexible pipe clamping sleeve assembly comprises the extruded sleeve that is used to compress flexible pipe and with outside thread pipeline section screw-thread fit and can promote the thread bush of extruded sleeve axial motion, described thread bush and extruded sleeve are rotatably assorted at circumferencial direction.
Further, described extruded sleeve end is provided with outer ring boss, and described thread bush end is provided with interior annular boss, and its outer ring boss was arranged at interior annular boss end face after described extruded sleeve inserted thread bush;
Further, described extruded sleeve pipeline is a conical pipeline, and described extruded sleeve and taper pipeline section cooperate the conical surface clamping structure that is formed for grip both hose;
Further, described outside thread pipeline section one end is provided with the taper pipeline section, and the other end is provided with infusion pump and connects pipeline section, and described infusion pump connection pipeline section is provided with outside thread or the internal thread with infusion pump outlet section screw-thread fit;
Further, described outside thread pipeline section two ends are provided with the taper pipeline section;
Further described taper pipeline section outer surface is or/and extruded sleeve conical pipeline surface is provided with annular groove.
The beneficial effects of the utility model: the utility model Drop-proof leakage proof hose coupling, by the rotation thread bush, flexible pipe clamping sleeve assembly is moved vertically, the intersegmental spacing of extruded sleeve and conical pipe is just dwindled gradually, extruded sleeve applies extruding force with firm being clamped between extruded sleeve and the taper pipeline section of flexible pipe to flexible pipe, and the flexible pipe compression area is big, and compression clamping power is big, and the flexible pipe distortion evenly, guaranteed that flexible pipe can not come off or rupture when work; Simultaneously the pressure of clamping sleeve deforms flexible pipe, flexible pipe is embedded in the annular groove on taper pipeline section outer surface and extruded sleeve conical pipeline surface forms ring structure, prevents the joint seepage, and ring structure has guaranteed that further flexible pipe can not come off simultaneously.
