Abstract
The utility model discloses a rivet for a blind hole. The rivet comprises a cap and a hole column. The cap is fixedly arranged on one end surface of the hole column, a sharp portion is formed on the other end surface of the hole column, and the end, which is close to the cap, of the hole column is inwardly sunken along the peripheral direction of the corresponding side surface of the hole column to form an annular groove. The rivet for the blind hole has the advantages that after the hole column of the rivet is placed in a blind hole position of a metal part, the sharp portion on the end surface of the hole column is squeezed into metal materials under the end surface of the hole column under the effect of external force, metal materials on the side surfaces of the hole column are squeezed by the side surfaces of the hole column, accordingly, the partial metal materials are completely squeezed into the annular groove under the joint actions of the sharp portion and the side surfaces of the hole column, and the annular groove is filled compactly; the sharp portion is squeezed into the metal materials, and a double-positioning effect can be realized for the rivet, so that a self-riveting effect of the rivet can be realized; the rivet is simple in structure and can be mounted easily and quickly, cracking due to impact and other negative phenomena can be prevented, and the like.
Description
Technical field
The utility model relates to a kind of rivet, relates in particular to a kind of blind hole rivet.
Background technique
At the electronic components such as mobile phone, computer, 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, butt-welding fitting status requirement is very accurate simultaneously, while therefore welding, must guarantee that the final position of weldment need be aimed at the solder joint impacting with laser beam.Another kind is to utilize metal rivet processed to be arranged on positioning hole, then impacts rivet with red needle, makes the open-ended end of rivet be hit and be out of shape and open and be pressed on fixture, to form rivet stationary state.But; when actual job; rivet pipe portion opening end opens distortion during being hit; often can there is powerful cracking 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 virgin metal rivet has in the time impacting by red needle.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, claimant on February 21st, 2013 applied for to Patent Office that application number is CN201310055721.8 from 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 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 utility model provides a kind of blind hole rivet, not only installs simply, rapidly, and can not producing breaks waits other bad phenomenon generations, and difficult drop-off.
The utility model 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 an end face of this Kong Zhu, on the other end of described Kong Zhu, form a tip, this Kong Zhu circumferentially concaves and forms an annular recess near a Yan Qi side, end of described cap head.
As further improvement of the utility model, 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 further improvement of the utility model, described annular recess is less than the radius of curvature of its opposite side in the radius of curvature of the close first side of described cap along the section of described hole mast axis.
As further improvement of the utility model, 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 beneficial effects of the utility model are: 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 the Kong Zhu of this rivet inserts behind metalwork blind hole position, tip on the styletable face of hole is squeezed in the metallic material under the styletable face of hole under external force, the metallic material of post side, hole is also subject to the extruding of post side, hole simultaneously, jointly make part metals material be pressed into completely in annular recess, make the well-offer of annular recess filling, tip is squeezed in metallic material simultaneously, also clamp-on annular recess with part material 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.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model riveting pre-structure schematic diagram in use;
Fig. 3 is structural representation after the utility model 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 utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, for a preferred embodiment of rivet for blind hole described in the utility model, comprise cap head 1 and hole post 2, this cap head is fixedly arranged on an end face of this Kong Zhu, on the other end of Kong Zhu, form a tip 21, 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 and the other end of described Kong Zhu overlap, the center line of this conical tip and the dead in line of described Kong Zhu.This Kong Zhu circumferentially concaves and forms an annular recess 22 near a Yan Qi side, end of cap head, and this annular recess is less than the radius of curvature of its opposite side in the radius of curvature of the close first side of cap along the section of hole mast axis.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 cap end surface with towards the power of its hole post direction (in figure downwards), tip on the styletable face of hole is squeezed in the metallic material under the styletable face of hole under external force, the metallic material of post side, hole is also subject to the extruding of post side, hole simultaneously, jointly make part metals material be pressed into completely in annular recess, as shown in Figure 3, be the structural representation after riveted.Due to the He Kongzhu side, tip of this rivet Double Pressures to blind hole, what not only make that material in annular recess fills is well-offer, and tip is also pressed in metallic material, can play Dual positioning effect, not only realize from riveted, and difficult drop-off, the quality of improving product and working life.
