Abstract
The invention discloses a rivet for a blind hole, which comprises a cap head and a hole column, wherein the cap head is fixedly arranged on one end face of the hole column; a tip part is formed on the other end face of the hole column; one end part of the hole column near to the cap head concaves inwards in the side surface circumferential direction of the hole column to form an annular groove. After the hole column of the rivet for the blind hole is placed into a blind hole of a metal piece, the tip part on the end face of the hole column is squeezed into metal materials below the end faces of the hole column under the action of external forces, at the same time, metal materials on the side surface of the hole column are squeezed by the side surface of the hole column, as a result, partial metal materials are completely squeezed into the annular groove jointly to enable the annular groove to be better filled; besides, the tip part squeezed into the metal materials can have a dual-positioning function on the rivet, so as to realize the automatic riveting of the rivet; moreover, the rivet further has the advantages that the structure is simple, the mounting is simple and fast, and breakage and other undesirable phenomena caused by impact are avoided.
Description
Technical field
The present invention relates to a kind of rivet, relate in particular to a kind of blind hole rivet.
Background technique
, at electronic components such as mobile phone, computers, especially in the processing procedure of multilayer circuit board, generally have being fixedly connected with between multilayer circuit board or other elements.At present, main Placement has two kinds, and the one, adopt laser beam welding, but laser welding equipment involves great expense, the butt-welding fitting status requirement is very accurate simultaneously, while therefore welding, must guarantee that the final position of weldment needs aim at the solder joint that laser beam will impact.Another kind is to utilize the metal-made rivet to be arranged on positioning hole, then with red needle, impacts rivet, makes the open-ended end of rivet be hit and be out of shape and open and be pressed on fixture, to form the rivet stationary state.But; during actual job; when rivet pipe section opening end opens distortion being hit; often powerful cracking can occur and produce jointly a small amount of conduction fracture detritus, and drop on circuit board to be connected or other devices, cause short circuit; Given this shortcoming; have part manufacturer to change metal rivet into plastic material, but the rivet poor ductility of plastic material often can be broken and cause reaching the riveted retention force that the virgin metal rivet has when with red needle, impacting.In addition, above-mentioned two kinds of means of fixation, operate more loaded down with trivial detailsly, and installation efficiency is also lower.
In order to address the above problem, the claimant on February 21st, 2013 to Patent Office applied for application number be CN201310055721.8 from the riveted rivet, this rivet can be realized from riveted, install simply, fast, can not produce and impact breaking and other bad phenomenon generations of causing, but this rivet is when being used for blind hole, if the metallic material of rivet hole post side can not enough be expressed in annular recess, cause coupling mechanism force inadequate, easily come off, thereby affect the quality of product and normally use.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of blind hole rivet, not only install simply, rapidly, can not producing breaks waits other bad phenomenon generations, and difficult drop-off.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of blind hole rivet, comprise cap head and Kong Zhu, this cap head is fixedly arranged on the end face of this Kong Zhu, form a tip on the other end of described Kong Zhu, an end of the close described cap head of this Kong Zhu circumferentially concaves along its side and forms an annular recess.
As a further improvement on the present invention, described cap head has columniform the first cap head and the second cap head, and described the second cap head is between described the first cap head and Kong Zhu, and the diameter of the first cap head is greater than the diameter of the second cap head.
As a further improvement on the present invention, described annular recess along the section of described hole mast axis in the radius of curvature of the radius of curvature near the first side of described cap less than its opposite side.
As a further improvement on the present invention, it is conical that described tip is, and the bottom surface of this conical tip overlaps with the other end of described Kong Zhu, the center line of this conical tip and the dead in line of described Kong Zhu.
the invention has the beneficial effects as follows: this rivet is because Kong Zhu is provided with annular recess, Kong Zhu is provided with tip away from the end face of its cap head, therefore after the Kong Zhu of this rivet inserts metalwork blind hole position, tip on the styletable face of hole is squeezed in metallic material under the styletable face of hole under external force, the metallic material of post side, hole also is subject to the extruding of post side, hole simultaneously, the part metals material is pressed in annular recess fully, make the well-offer of annular recess filling, tip is squeezed in metallic material simultaneously, also with the part material, clamp-on annular recess the same, can play two positioning actions to rivet, thereby realize rivet from riveted.This rivet also has simple in structure, installs simply, quick, can not produce advantages such as impacting breaking of causing and other bad phenomenon generations.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the present invention's riveting pre-structure schematic diagram in use;
Fig. 3 is structural representation after the present invention's riveting in use.
By reference to the accompanying drawings, make the following instructions:
1---cap head 11---first cap head
12---the second cap head
2---Kong Zhu
21---tip 22---annular recess
Embodiment
By reference to the accompanying drawings, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment, the simple equivalence of namely in every case with the present patent application the scope of the claims and description, being done changes and modifies, within all still belonging to patent covering scope of the present invention.
As shown in Figure 1, for the preferred embodiment of blind hole of the present invention with rivet, comprise cap head 1 and hole post 2, this cap head is fixedly arranged on the end face of this Kong Zhu, form a tip 21 on the other end of Kong Zhu, it is conical that this tip is, and is positioned at the center portion of post other end, hole, that is: the bottom surface of this conical tip overlaps with the other end of described Kong Zhu, the center line of this conical tip and the dead in line of described Kong Zhu.This Kong Zhu circumferentially concaves along its side and forms an annular recess 22 near an end of cap head, this annular recess along the section of hole mast axis in the radius of curvature of the radius of curvature near the first side of cap less than its opposite side.Described cap head has columniform the first cap head 11 and the second cap head 12, and described the second cap head is between described the first cap head and Kong Zhu, and the diameter of the first cap head is greater than the diameter of the second cap head.
This rivet in use, is placed to its Kong Zhu the blind hole position of metalwork, as shown in Figure 2, is this blind hole structural representation of rivet before riveted.Then give the cap end surface with the power towards its hole post direction (namely in figure downwards), tip on the styletable face of hole is squeezed in metallic material under the styletable face of hole under external force, the metallic material of post side, hole also is subject to the extruding of post side, hole simultaneously, the part metals material is pressed in annular recess fully, as shown in Figure 3, be the structural representation after riveted.Due to the tip of this rivet and post side, the hole Double Pressures to blind hole, not only make the well-offer of the interior material filling of annular recess, and tip also is pressed in metallic material, can play the Dual positioning effect, not only realized from riveted, and difficult drop-off, the quality of improving product and working life.
