Preferably, the first convex plug is provided with more than one and is arranged at intervals according to the width distance of the first convex plug, and the first convex plug surrounds the front end of the joint cap.

Furthermore, second convex plug is unanimous with first convex plug structure, just second convex plug is the dislocation formula cooperation with first convex plug, and second convex plug is gone into the back with first convex plug card each other, and the texture of its junction is the wave form.

Preferably, the bolt hole comprises a circular opening and a strip-shaped opening stretching across the middle of the circular opening, and the circular opening and the strip-shaped opening are arranged in an integrated mode.

Furthermore, the limiting bolt comprises a bolt head matched with the circular open hole and a bar-shaped baffle rod stretching across the middle part of the bolt head and matched with the bar-shaped open hole, and the length of the bar-shaped baffle rod is greater than the diameter of the circular open hole.

Furthermore, a maximum clearance D and a minimum clearance D are formed between the wavy bulge and the inner wall of the joint cap, and the length of the plug pin part below the strip-shaped stop lever is greater than the minimum clearance D and less than or equal to the maximum clearance D, so that a blocking structure is formed.

The utility model has the advantages that:

wave-like arch through the spliced pole lateral surface cooperatees with the joint cap of cavity cell body design and inserts, and cooperate bolt hole and spacing bolt, carry on spacingly to the joint body, avoid the joint body to deviate from and connect the cap, realize a enclosed construction, the first convex plug of collocation is pegged graft with second convex plug simultaneously, seal the external connection department that connects the body and connect the cap, realize secondary enclosed construction, realize sealedly through foretell dual enclosed construction, compare in traditional hose nipple, it is connected not only more convenient, sealed effect is also the preferred.
