At present automobile, aviation industry production development are rapid, and the occasion that the user need to rivet is also in variation (as single face, blind hole), and therefore the connection area for automobile, Aviation Industry has proposed requirements at the higher level.Bolt in the market can't satisfy the required diversified occasion of automobile, Aviation Industry, load is tightly connected.
At present, the bolt that uses in automobile, Aviation Industry field can only from the two sides of workpiece, need complete sealing by the sealing object on sealing on Placement.
Developing a kind of bolt that can better satisfy automobile industry, Aviation Industry demand is the direction that people make great efforts.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of rivet type bolt is provided, but the strong single face of its sealing, anti-seismic performance, blind hole connect, be applicable to automobile industry, Aviation Industry connects, and is applied widely, connects safe and reliable.
The technological scheme that provides according to the utility model, a kind of rivet type bolt, comprise rivet nut and blind rivet, described rivet nut is provided with the counterbore coaxial with it, through hole, and described counter bore hole diameters is greater than through-hole diameter, described blind rivet runs through through hole and blind rivet upper end ailhead and is fastened on the boss that counterbore and through hole consist of, it is characterized in that: described ailhead lower end connecting nail core bar, on described blind rivet bar, breaking groove is set, described breaking groove is divided into up and down two-part with the blind rivet bar, the upper end arranges thread, and the lower end is polished rod; Be set with protecting jacket on described thread, described protecting jacket lower end is fastened in breaking groove, and described ailhead upper end is provided with chamfering.
As further improvement of the utility model, described ailhead diameter is greater than the thread protecting jacket.
As further improvement of the utility model, described ailhead surface with the convex stripe of parallel to an axis.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Connect fastening, sealing; Improved the resistivity of bolt to transverse vibration; Improved the resistivity of bolt to transverse vibration.

Embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 4, the utility model is a kind of rivet type bolt, comprise rivet nut 1 and blind rivet 5, described rivet nut 1 is provided with the counterbore coaxial with it 2, through hole 3, described counterbore 2 diameters are greater than through hole 3 diameters, described blind rivet 5 runs through through hole 3 and blind rivet 5 upper end ailheads 6 and is fastened on the boss that counterbore 2 and through hole 3 consist of, described ailhead 6 lower end connecting nail core bars 10, on described blind rivet bar 10, breaking groove 8 is set, described breaking groove 8 is divided into up and down two-part with blind rivet bar 10, the upper end arranges thread 7, and the lower end is polished rod; Be set with protecting jacket 4 on described thread 7, described protecting jacket 4 lower ends are fastened in breaking groove 8, and described ailhead 7 upper ends are provided with chamfering 9.
Described ailhead 6 diameters are greater than thread protecting jacket 4.
Described ailhead 6 surfaces with the convex stripe of parallel to an axis.
As shown in Figure 5, working procedure of the present utility model is as follows, in use, rivet nut 1 is put into the endoporus of object 11 to be connected, then the active force that pulls blind rivet bar 10 that the blind rivet 5 in rivet nut 1 is riveted with common riveting gun, ailhead 6 moves in through hole 3 under the ordering about of this active force.Ailhead 6 outwards expands rivet nut 1, the whole turgor voidlessnesss of riveted joint endoporus of riveted joint object.This moment, ailhead 6 continued to make protecting jacket 4 move down with blind rivet 5 to lower compression under the active force of riveted joint; In this process, breaking groove 8 place's fractures of blind rivet 5 also cause protecting jacket 4 to come off.
Ailhead 6 is in the process of riveting gun blind rivet core 5, ailhead 6 enters in the interior through hole 3 of rivet nut 1, and make the inwall of through hole 3 stressed, be close to voidlessness because of lower end surface and the riveting gun face of rivet nut 1 again, rivet nut 1 can only have outside expansion, it is filled full in the riveted joint endoporus of riveted joint object, increased surface of contact, the sealing of bolt.
The utility model protecting jacket 4 is provided with the protecting jacket endoporus; blind rivet 5 is provided with breaking groove 8; and make thread protecting jacket 4 be stuck in the interior formation one of breaking groove 8; when pulling blind rivet 5 in the interior motion of rivet nut 1; described protecting jacket 4 is enclosed within outside thread 7, makes thread 7 and protecting jacket 4 enter simultaneously the riveting gun endoporus because the thread of thread 7 under the protection of protecting jacket 4 can be not destroyed.
The utility model ailhead 6 is provided with parallel and axial antiskid thread, in staking enters the through hole 3 of rivet nut 1, because of the diameter of through hole 3 diameters less than ailhead 6, antiskid thread on ailhead 6 can be embedded in through hole 3 and make thread 7 not take axially as the circular movement in the center of circle.Described ailhead 6 upper ends are provided with chamfering 9, and (the rivet nut material is aluminium, and bilateral chamfering 9 is 67.3 degree to be designed to different angles according to rivet nut 1 different materials hydromechanics direction chamfering 9; The rivet nut material is stainless steel, and bilateral chamfering is 72.6 degree; The rivet nut material is carbon steel, and bilateral chamfering is 73.8 degree) make the closing in that is complementary with ailhead chamfering 9 that is shrunk to of rivet nut 1 inner via hole 3, make thread 7 there is no axial movement.All the time the face that is close to the riveted joint object due to rifle face in the staking process of riveting gun can be suitable for different thickness of riveting things, is specially adapted to automobile industry, Aviation Industry and lightweight material.The rivet type bolt can adopt the material manufacturing of differing texture, and intensity is high, and using scope can expand to the connection of any object.
Thereby the utility model can produce distortion and well junction surface be combined.Bolt distortion radially also can be filled up riveted holes, prevent that the gap from producing.Riveted joint is in an extrusion stretching process, a cylinder rivet nut is squeezed into the connecting position of plate and forms, but also be extruded according to the shape in aperture, consists of the tie point that individual very high strength is arranged.
