Riveting portion is turned at one, and the tank is located at the head and described turns between riveting portion.
Specifically, the angle between the side wall of the groove and the lateral wall of the bar portion is acute angle.
Specifically, the thickness for turning over riveting portion is gradually reduced along the direction far from the head.
Specifically, the section of the tank is in arc-shaped.
Specifically, being additionally provided with a flower teeth portion, week of the colored teeth portion along the bar portion between the tank and the head
To being uniformly arranged.
Specifically, the rivet is made of steel, aluminium or copper material.
Specifically, the rivet has along the hole that its axis penetrates through.
The beneficial effects of the utility model are as follows: rivet described in the present embodiment is to only with the work of narrow installation space
When part is riveted, the bar portion of rivet is put into the riveted holes of workpiece, turns over riveting portion facing to certain degree of hardness when rivet
Plate when, need to only apply certain pressure to the head of rivet, alternatively, using a plate with certain degree of hardness to turning over riveting portion
Applying axial pressure can realize without using special installation punch-pin to axially move on the axis of rivet and turn over riveting
The outside flat-die in portion turns over riveting, substantially reduces the installation space of rivet；And this implements the pocket structure of the rivet, can be used for absorbing
In riveting process, the material that workpiece is extruded when being plastically deformed, namely play the role of discharge.
For the above and other objects, features and advantages of the utility model can be clearer and more comprehensible, preferable reality is cited below particularly
Example is applied, and cooperates institute's accompanying drawings, is described in detail below.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of rivet one described in the utility model embodiment；
Fig. 2 is another structural schematic diagram of rivet described in the utility model embodiment.
The appended drawing reference of the figures above: the head 10-, 20- bar portion, 21- tank, 22- groove, 221- side wall, the outside 23-
Wall.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As described in Figure 1, rivet described in the present embodiment includes head 10 and the bar portion 20 that connect with the head 10, institute
The lateral wall 23 for stating bar portion 20 is equipped with a tank 21 for being used for discharge, circumferential direction setting of the tank 21 along the bar portion 20, institute
It states bar portion 20 and is equipped with a groove 22 far from the one end on the head 10, the groove 22 is recessed along the axis direction of the bar portion 20
It falls into, specifically, end face of the groove 22 from the bar portion 20 far from described 10 one end of head is to the close head 10
Direction recess, the groove 22 has one side wall 221 and bottom, and the axis of the bottom of the groove 22 and the bar portion 20 hangs down
Directly, one is formed between the side wall 221 of the groove 22 and the lateral wall 23 of the bar portion 20 and turn over riveting portion, preferably, the groove
22 depth is between 0.5-0.8mm.The tank 21 is located at the head 10 and described turns between riveting portion.
Using the above structure, rivet described in the present embodiment is riveted to the workpiece only with narrow installation space
When, the bar portion 20 of rivet is put into the riveted holes of workpiece, when rivet turn over riveting portion facing to certain degree of hardness plate when,
Only need to head 10 to rivet apply certain pressure, alternatively, using the plate with certain degree of hardness to turn over riveting portion apply it is axial
Pressure can realize that turn over riveting portion puts down outward without using special installation punch-pin to axially move on the axis of rivet
Mould turns over riveting, substantially reduces the installation space of rivet；And this implements 21 structure of tank of the rivet, can be used for absorbing and riveted
Cheng Zhong, the material that workpiece is extruded when being plastically deformed, namely play the role of discharge.
Specifically, as shown in Figure 1, having one between the side wall 221 of the groove 22 and the lateral wall 23 of the bar portion 20
Angle, the angle are an acute angle.Further, the thickness for turning over riveting portion gradually subtracts along the direction far from the head 10
It is small, preferably, the minimum thickness for turning over riveting portion is between 0.1-0.15mm.In other words, the bottom of the groove 22 and its
An obtuse angle is formed between side wall 211, the degree at the obtuse angle is between 100-120 °.Using this scheme, be conducive to assemble
Cheng Zhong can be completed using lesser pressure and turn over the flat-die in riveting portion and turn over riveting, further reduces the peace of rivet described in the present embodiment
Fill space.
Specifically, the section of the tank 21 is in arc-shaped as described in Figure 1, which can be regular arc-shaped, can also
Think irregular roundness arcuation.The tank 21 effectively improves the rivet to the applicability of the workpiece within the scope of certain thickness, tool
For body, in certain thickness range, when the thickness of workpiece is smaller, then the material being squeezed into tank 21 is less, and works as
The thickness of workpiece is larger, then the material being squeezed into tank 21 is more.Certainly, the tank 21 can also be square or triangle
Shape, but the scheme that tank 21 is in irregular roundness arcuation is used in the present embodiment, it can be concentrated to avoid 21 stress of tank, shadow
Ring the bonding strength of rivet head 10 and bar portion 20.Further, as shown in Fig. 2, the tank 21 and the head 10 it
Between be additionally provided with a flower teeth portion, the colored teeth portion is uniformly arranged along the circumferential direction of the bar portion 20, and the colored teeth portion further improves
Applicability of the rivet to the work of different-thickness.
As shown in Figure 1, it is tubular rivet, Ke Yi that the rivet, which has along the hole that its axis penetrates through namely the rivet,
Material is saved under the premise of meeting bonding strength.The rivet is made of steel, aluminium or copper material.
Specific embodiment is applied in the utility model to be expounded the principles of the present invention and embodiment, with
The explanation of upper embodiment is merely used to help understand the method and its core concept of the utility model；Meanwhile for this field
Those skilled in the art, based on the idea of the present invention, there will be changes in the specific implementation manner and application range, comprehensive
Upper described, the content of the present specification should not be construed as a limitation of the present invention.
