Abstract
The utility model relates to a rivet, in particular to an inner-press and inner-drive rivet. The utility model adopts the technical scheme as follows: a limiting convex ring protruding outwards is connected with the outer side wall of the bottom end of a nail cylinder; an integrated inner hole is arranged inside the nail cylinder and the limiting convex ring; two or more vertically-downward eversion depressions are formed on the inner wall surface of the nail cylinder from the top end thereof; a nail core is inserted in the inner hole; a bearing part is arranged on the outer side wall of the lower section of the nail core; the upper end part of the nail core is a nail head part with the diameter larger than the inner hole; the bottom end of the nail head part is an inverted conical body; the lower end part of the conical body is partially inserted in the inner hole; cracked depressions are formed on the outer side wall of the nail core at the lower part of the nail head part; and the distance between the top end surface of the nail cylinder and the bottom end surface of the limiting convex ring is larger than the distance between the contact part of the nail head part and the inner hole, and the cracked depression. The utility model has the advantages of good riveting effect, high strength, and wide application range.
Description
Technical field
The utility model relates to a kind of rivet, the rivet of blooming in specifically a kind of interior compeling.
Background technique
At present, garland snap riveting nail has been widely used in the riveted joint of nonmetallic plane or non-planar junction member.The design proposal of garland rivet is: the ailhead bottom at the nail core is shaped on four edges, during staking, utilizes this four edges that the tubular pin body is cut to pintongs, forms the shape of blooming.If the four edges system of ailhead bottom is inhomogeneous or not sharp, will causes following closely body and open three lobes and even do not ftracture, influence riveted joint effect.Garland snap riveting nail, intensity is low, the riveted of using scope limitation and nonmetal soft material.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of riveted joint is effective, intensity is high, using scope is wide, especially is fit to the rivet of blooming in interior the compeling with nonmetal soft material riveted.
The technological scheme that provides according to the utility model, outer side wall in nail tube bottom connects outwardly directed position limiting convex ring, be provided with the endoporus of integrated in nail tube and the position limiting convex ring, rise by its top at a nail tube internal face and to offer two or more depression of turning up straight down, in endoporus, be plugged with the nail core, the hypomere outer side wall of nail core is a forced section, upper end portion at the nail core is the nail head of diameter greater than endoporus, the cone of the bottom of nail head for standing upside down, this cone underpart is partially submerged in the endoporus, nail core outer side wall below the nail head offers the depression that ruptures, and nail tube top end arrives the distance that ruptures between the depression to the distance between the position limiting convex ring bottom end greater than nail head and endoporus contacting part.
The described depression of turning up is 3～5, and they are evenly distributed on the nail tube internal face.All depression bottoms of turning up are concordant, and the length of the depression of turning up is consistent to the distance between the fracture depression with the endoporus contacting part with nail head.Described forced section is one section screw thread of nail core outer side wall processing.The bottom of nail core is provided with the guiding surface that is inverted cone.
After the utility model riveted joint, the ailhead of nail core can not come off, but embeds the nail body, guarantees to rivet fastening, not loosening.On the other hand, the rivet of blooming in interior the compeling adopts the steel material manufacturing, the intensity height, and using scope can expand to the riveted joint of hardware.

Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: on the outer side wall of nail tube 1 bottom, connect outwardly directed position limiting convex ring 2, be provided with the endoporus 3 of integrated in nail tube 1 and the position limiting convex ring 2, rise by its top at nail tube 1 internal face and to offer two or more depression 4 of turning up straight down, in endoporus 3, be plugged with nail core 5, the hypomere outer side wall of nail core 5 is a forced section 6, upper end portion at nail core 5 is the nail head 7 of diameter greater than endoporus 3, the cone of the bottom of nail head 7 for standing upside down, this cone underpart is partially submerged in the endoporus 3, nail core 5 outer side walls of nail head 7 belows offer the depression 8 that ruptures, and nail tube 1 top end arrives the distance that ruptures between the depression 8 to the distance between position limiting convex ring 2 bottom ends greater than nail head 7 and endoporus 3 contacting parts.
The described depression 4 of turning up is 3～5, and they are evenly distributed on nail tube 1 internal face.All depression 4 bottoms of turning up are concordant, and the length of the depression 4 of turning up is consistent to the distance between the fracture depression 8 with endoporus 3 contacting parts with nail head 7.Described forced section 6 is one section screw thread of nail core 5 outer side walls processing.The bottom of nail core 5 is provided with the guiding surface 9 that is inverted cone.
The nail head 7 of the nail core 5 in the utility model is made cone boss and is added semicircular structure, and the inwall of nail tube 1 uncovered end is a square.During staking, nail tube 1 splits automatically at four depression 4 places of turning up of the quadrilateral inwall of following closely tube 1 under nail head 7 extruding of nail core 5, forms four petal shapes to turning up.Because nail tube 1 quadrilateral inwall, has guaranteed that nail tube 1 one fixes on this depression 4 of turning up everywhere and splits at the thinner thickness at depression 4 places that turns up, and finishes the shape riveted joint effect of blooming smoothly.After the riveted joint, the ailhead of nail core can not come off, but embeds the nail body, guarantees to rivet fastening, not loosening.On the other hand, the rivet of blooming in interior the compeling adopts the steel material manufacturing, the intensity height, and using scope can expand to the riveted joint of hardware.
