Utility model content
The purpose of this utility model aims to provide that a kind of simple and reasonable, flexible operation, good toughness, connection are firm, the expansion knot of long service life, to overcome weak point of the prior art.
Expand and tie by the one of this object design, comprise expansion main body and expansion nut, its architectural feature is that expansion main body and expansion nut are Split type structure, in expansion main body, is provided with resilient prongs, is provided with slot on expansion nut, and resilient prongs is inserted in slot.
Further, in described expansion main body, be provided with guide groove, be provided with outstanding guide ledges on expansion nut, this guide ledges is inserted in guide groove.
Further, described guide groove is more than two, and guide groove is arranged on the side of expansion main body; Guide ledges setting corresponding to guide groove.
Further, be provided with retaining boss in described slot, resilient prongs end is provided with retaining overhead kick, and this retaining overhead kick is hooked on retaining boss.
Further, be also provided with positioning step in described slot, resilient prongs end is provided with positive stop lug boss, and this positive stop lug boss is crimped on positioning step.
Further, described retaining overhead kick is positioned at a side of resilient prongs end, and positive stop lug boss is positioned at the opposite side of resilient prongs end.
Further, described resilient prongs is more than two, resilient prongs be arranged on expansion main body side; Slot setting corresponding to resilient prongs.
Further, the end face of described expansion nut is the conical surface.
Further, described resilient prongs is L-shaped.
Further, described expansion nut is harder than expansion main body.
Expansion main body in the utility model and expansion nut are Split type structure, that is to say, whole expansion knot is divided into bi-material to be made, and is combined, wherein by two parts, the toughness of material of expansion main body is good, not easy fracture, long service life. the material of expansion nut is hard, internal whorl torsion is large, tightens safe and reliable.
The utility model adopts after above-mentioned technical scheme, and the mutual fastening of expansion main body and expansion nut, after its assembling completes, just again cannot get loose, solid and reliable.
Resilient prongs in the utility model is L-shaped, thereby has larger elasticity and regulate surplus.
The utility model is the installation fitting of toilet and cover plate, for cover plate is fixed on to ceramic bowl, mainly uses on the toilet pottery in the toilets such as family, club, hotel, apartment, station.
The utlity model has that simple and reasonable, flexible operation, good toughness, connection are firm, the feature of long service life.
