Diameter size matches.
Further, the anti-slop serrations are located in nut head circumferentially array-like setting, are provided with and break in the blind rivet
Portion, the internal screw thread are located in nut head far from blind rivet head, and the turn-up portion has multiple.
Further, the anti-slop serrations are located in nut head far from blind rivet head, and portion's size of breaking is less than blind rivet ruler
Very little, the turn-up portion is located in nut head circumferentially array-like setting.
Further, the portion of breaking is located in blind rivet at blind rivet head, is respectively provided in the blind rivet head and turn-up portion
There is chamfering.
The utility model has the following beneficial effects: providing a kind of Drawing-Core staking softwood matter embedded nut, pass through blind rivet, nut
Head, internal screw thread, blind rivet head and the portion of breaking are used in conjunction with each other, and realization is tight in the screw thread of various softwood lumbers or fabric leather
Gu effect used in, high production efficiency, no security risk have a wide range of application.

In figure: 1, blind rivet；2, nut head；3, blind rivet head；4, turn-up portion；5, anti-slop serrations；6, internal screw thread；7, portion is broken；8,
Arc surface；9, cutout unit；10, face is held out against；11, movement slots.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Referring to figs. 1 to Fig. 3, a kind of Drawing-Core staking softwood matter embedded nut, including blind rivet 1, nut head 2 and blind rivet head
3；The blind rivet 1 is located inside nut head 2, and internal screw thread 6 is provided in the nut head 2 and holds out against face 10, is set in the blind rivet 1
It is equipped with blind rivet head 3, is provided with arc surface 8 on the blind rivet head 3, so that blind rivet head 3 is entered movement slots 11 for opening turn-up portion 4
It is interior, it is provided with cutout unit 9 in the nut head 2, for guaranteeing that blind rivet head 3 can go deep into movement slots 11, the cutout unit 9 is located at
In nut head 2 at blind rivet head 3, the cutout unit 9 is located in nut head 2 circumferentially array-like setting, makes 4 stress of turn-up portion
Uniformly, it is provided with anti-slop serrations 5 in the nut head 2, turn-up portion 4 and movement slots 11, the circular arc are provided in the nut head 2
8 size of face is matched with 11 size of movement slots, and 2 inner wall size of nut head is matched with 1 outer diameter of blind rivet, it is ensured that blind rivet
1 can just be inserted into nut head 2 and will not Automatic-falling.
The anti-slop serrations 5 are located in nut head 2 circumferentially array-like setting, are provided with the portion of breaking 7 in the blind rivet 1, fill
Breaking portion when breaking, the internal screw thread 6 are located in nut head 2 far from blind rivet head 3, and the turn-up portion 4 has multiple.
The anti-slop serrations 5 are located in nut head 2 far from blind rivet head 3, and 7 size of portion of breaking is less than 1 size of blind rivet, institute
It states turn-up portion 4 and is located in nut head 2 circumferentially array-like setting.
The portion 7 that breaks is located in blind rivet 1 at blind rivet head 3, is provided with down in the blind rivet head 3 and turn-up portion 4
Angle.
The working principle of the utility model are as follows: when starting to work: nut being put into the hole location on soft material, by nut
First 2 compress soft material, and with riveting gun blind rivet core 1, the blind rivet head 3 of blind rivet 1 is expressed to turning over for nut head 2 by the pulling force of riveting gun
Edge 4, because by powerful pulling force effect, blind rivet head 3 squeezes arc surface 8, and 8 part of arc surface is squeezed between turn-up portion 4, blind rivet head 3
Into in movement slots 11, so that turn-up portion 4 is softened and swells, a horn mouth is formed, simultaneously because blind rivet head 3 is than turn-up portion 4
Hardness is high, and blind rivet head 3 is just pressed into movement slots 11 and by 4 jam-packed of turn-up portion；It is described when blind rivet head 3 is expressed to the face 10 of holding out against
Turn-up portion 4 struts completely, and turn-up portion 4 fastens the bore edges on soft material, and the blind rivet head 3 cannot be squeezed at this time
In internal screw thread 6, but the pulling force of riveting gun is also continuing, and blind rivet 1 disconnects in the portion of breaking 7 under the pulling force effect for continuing to increase, nail
Core 1 and blind rivet head 3 fall off simultaneously, and nut head 2 stays in the hole location on soft material, and work terminates.
The utility model is not confined to these for being further described to the utility model by above-described embodiment
Specific embodiment.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc.,
It is interpreted as being within the protection scope of the utility model.
