Description
Technical field
The utility model is related to the technical field of nut, more particularly to the technical field of self-clinching nut.
Background technology
With the development trend of automotive light weight technology, the thin-wall section in closed cross-section or non-close section is in manufactures such as automobiles
The application of industry is on the increase, it is mainly used for that auto parts and components are fixedly mounted, and fixed installation mode common at present mainly has
Two kinds：First, opening up through-hole on thin-wall section, when installing parts, bolt, which is passed through, needs parts and thin-walled to be mounted
The through-hole of section bar, and tightened using nut, it would be desirable to the parts of installation are fixed on thin-wall section.However it uses this
Although mode bonding strength is higher, easily thin-wall section is caused to squeeze, thin-wall section is caused to deform, and one end of bolt
It can be pierced by from the through-hole of thin-wall section, so as to not only affect beauty, but also affect the flatness on thin-wall section surface, occupy
Extra space, easily causes to interfere so that the installation of other parts becomes very to the normal mounting of other parts
It is inconvenient.Second is that the welded nut on thin-wall section, it would be desirable to which the parts being fixed on thin-wall section are bolted rotation
It puts on nut.However although occupied space is smaller in this way, its bonding strength is poor, after long-term use, spiral shell
Mother easily comes off from thin-wall section.
Utility model content
The purpose of this utility model is exactly to provide a kind of simple in structure to solve above-mentioned deficiency, and locking securely, can
It effectively prevent loosening, and certain inner support can be played the role of to thin-wall section, and thin-wall section surface can be kept to put down after installing
Whole section bar supports self-clinching nut with flush mounting type.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows：
Section bar supports self-clinching nut with flush mounting type, it is made of cylinder, and the cylinder is integrally cylindrical, at the top of cylinder
Lateral wall on be provided with annular convex platform, the positive stop lug boss extended downwardly is provided in the bottom of cylinder, is opened up in the cylinder
There is centre bore, be provided with internal thread on the madial wall in the body centre hole, opened up on the lateral wall of the positive stop lug boss
There is annular locking slot, the top setting of the cylinder positive stop lug boss is in embedded division.
Annular knurl is provided on the lateral wall of the embedded division
The centre bore is through-hole.
The centre bore is blind hole.
The annular convex platform is tapered.
The utility model is using the attainable advantageous effect of above-mentioned technical solution institute：It is embedding by the embedded division of cylinder
Enter in thin-wall section, while thin-wall section is deformed upon and is embedded into annular locking slot, by this self-clinching nut, securely lock is put thin
On wall-shaped material, so as to play good locking effect, it can be effectively prevent to get loose, be set on the lateral wall of embedded division
There is annular knurl, so as to play good anti-rotation effect, further improve locking intensity；This self-clinching nut is installed to thin wall type
After on material, upper and lower both ends are concordant with the upper and lower surface of thin-wall section respectively, so as to be not take up redundant space, can keep thin-walled
Surface of profile it is smooth, will not be interfered with other parts, it is not only beautiful, but also will not be to the normal peace of other parts
Dress impacts；And it needs to be fixed on after the component on thin-wall section is fixedly mounted on this self-clinching nut, it will not be to thin-walled
Section bar causes to squeeze, and plays the role of certain inner support.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of Fig. 1；
Fig. 3 and Fig. 4 is the scheme of installation of the utility model.
Specific embodiment
As shown in Fig. 1 and Fig. 2, section bar supports self-clinching nut with flush mounting type, it is made of cylinder 1, and the cylinder 1 is whole to be in
It is cylindric, annular convex platform 2 is provided on the lateral wall at 1 top of cylinder, which can set tapered.In cylinder 1
Bottom is provided with the positive stop lug boss 3 extended downwardly, and centre bore 4 is offered in the cylinder 1, which can be through-hole
It can be blind hole, be provided with internal thread 8 on the madial wall of 1 centre bore 4 of cylinder, need be fixed on thin-wall section 9 zero
Part can be bolted on the internal thread 8 for being located on centre bore 4.Annular is offered on the lateral wall of the positive stop lug boss 3
Locking slot 5, the top setting of 1 positive stop lug boss 3 of cylinder are provided with annular knurl in embedded division 6 on the lateral wall of the embedded division 6
7, with the anti-rotation played the role of.
As shown in Figure 3, this self-clinching nut when mounted, first opens up first through hole 10 and second respectively on thin-wall section 9
Then this self-clinching nut is caught in from first through hole 10 in thin-wall section 9 by through-hole 11, make 3 holding of positive stop lug boss in the second through-hole
In 11.Then, thin-wall section 9 is mounted on pedestal 12, as shown in Figure 4, punching press is carried out to this self-clinching nut by pressing plate 13,
Cylinder 1 is pressed down against, makes the 2 tight fit holding of annular convex platform of cylinder 1 in the first through hole 10 of thin-wall section 9, and make cylinder
The embedded division 6 of body 1 is embedded in the thin-wall section 9 at the second through-hole 11, while the thin-wall section 9 at the second through-hole 11 deforms upon
It is embedded into annular locking slot 5.
