Description

Wedge expanding nail

The utility model relates to a kind of hardware article, is the bloated nail of a kind of wedge-type specifically.

At present, be extensive use of swell fixture in house decoration and building industry.Swell fixture mostly is the expand tube formula, and this swell fixture needs baffle plate in use.During installation swell fixture with well is inserted porthole, insert screw with baffle plate and block sleeve pipe, and then use the nut tensioned screw.This swell fixture need have a baffle plate, and complex structure, screw are cylindrical, can not be used for suspended item, can only come suspended item by the baffle plate that it compressed.Cumbersome.

The purpose of this utility model provide a kind of can directly be used for suspended item fall the wedge-type nail that expands, its simple structure, easy to use, reliable.

The wedge-type that is achieved in that the utility model down expands to follow closely and comprises expand nail body 1 and bloated wedge 2 two-part.The end of following closely body 1 that expands has cross recess 3, and the bottom has taper to draw nest 5, and an aperture 6 is arranged.Draw nest 5 and form an annular sword 4 with the nail body outer round surface that expands.The nail body 1 that expands is opened on the end periphery of cross recess 3 and is shaped on annular barb 7.The other end of following closely body 1 that expands is the suspended end of extension article.The small column 8 that expands and to have on the wedge 2 external diameter to equate with aperture 6 on the nail body 1 that expands, bloated wedge 2 middle parts have a cylinder 9 more bigger than small column 8, and a round platform 10 is arranged at the bottom.

Accompanying drawing is depicted as several embodiment of the present utility model.

Fig. 1 is the bloated nail of wedge-type that has the single hole hangers, and wherein a is swollen nail, and b is the wedge that expands;
