Description
Technical field
The invention belongs to riveting technology field, more particularly to a kind of reversely explosion-proof rivet.
Background technology
The method for using welding in the connection of hyperbar, No leakage occasion at present.It is well known that welding consumed energy
It is very big, and no matter which kind of welding method, postwelding is always with the presence of welding residual stress, and simply the residual stress of distinct methods is big
Small different, the part of welding is simultaneously because the chilling of heat affected area, under conditions of carbon content is higher, easily produces quenching
Martensite, is easily cracked.Control not in place in welding process, easily produce stomata, slag inclusion, incomplete fusion, lack of penetration etc. lack
Fall into influence air-tightness.And there is severe working condition.
Problem above is solved, the riveting of fast self-plugging rivet can be used.As depicted in figs. 1 and 2, Fig. 1 is
State diagram of the existing cherry riveting in staking；Fig. 2 is the state diagram after existing self-plugging rivet riveting.Arrow side in Fig. 2
To pressure directions are represented, the operation principle of self-plugging rivet currently used in the market is riveting gun 10 by pulling blind rivet 11 to realize
, riveting is completed by a power from inside to outside, has the head of blind rivet 11 to stay in rivet nut 12 in midair so as to form one
Heart body.The external force that the head of blind rivet 11 is born in rivet nut 12 need to only reach that 20N just can be with national standard and international standard,
But the head of blind rivet 10 of rivet can be forgotten about it in the endoporus of rivet nut, can so destroy the endoporus of rivet nut 12.As long as having more than 20N's
Power is acted on the head of blind rivet 11, and the head of blind rivet 11 can compel to cause the riveting body of a perforation from rivet nut.Obvious existing core pulling
Rivet is it cannot be guaranteed that bearing anticyclonic requirement in the power of hyperbar, No leakage occasion 20N.
The content of the invention
It is an object of the invention to provide a kind of reversely explosion-proof rivet, it has simple in construction, compact, riveting reliable and stable
With the characteristics of air-tightness is high after riveting, with the above mentioned problem that exists when solving that hyperbar, No leakage occasion are riveted in the prior art.
For up to this purpose, the present invention uses following technical scheme：
A kind of reversely explosion-proof rivet, it includes blind rivet and rivet nut, wherein, the rivet nut includes nail body, the one of the nail body
End is provided with rivet nut shade, and the blind rivet includes assister bar, and one end of the assister bar is extended with ailhead connecting portion, the ailhead
Ailhead is extended with connecting portion, and the joint of the assister bar and the ailhead connecting portion is provided with blind rivet fracture, it is described
The ailhead is coordinated to offer half-via with nail, the blind rivet sets one end of ailhead to insert in the half-via, and described
Ailhead is stuck in half-via, and the rivet nut movement during staking, the ailhead is motionless.
Especially, the half-via and nail body are coaxial and be vertically arranged with the rivet nut shade.
Especially, the rivet nut shade and ailhead are oblate, spherical or square any.
Especially, the blind rivet fracture be the joint for being opened in assister bar and the ailhead connecting portion wedge shape lack
Mouthful.
Especially, the blind rivet, which is inserted, is stuck in ailhead in half-via by being molded in the half-via, and the power-assisted
The inwall close-fitting of bar, ailhead connecting portion and blind rivet fracture and half-via.
Especially, boss, the boss are provided with the blind rivet between blind rivet fracture and the ailhead connecting portion
Diameter be more than the diameter of the assister bar, the diameter of the assister bar is more than the diameter of the ailhead connecting portion.
Beneficial effects of the present invention are, compared with prior art the reversely explosion-proof rivet in riveting with traditional core pulling
Rivet staking is in opposite direction, and moving nail body is not moved ailhead during staking, and traditional self-plugging rivet is the motionless blind rivet movement of rivet nut.
After the completion of staking, ailhead is stopped in situ, and internal structure is not destroyed makes rivet nut into original enclosed construction, and air pressure can not be penetrated
Rivet body.Simultaneously it is in shade rivet nut shade to bear on the face of air pressure, is not only simple in structure, compact, reasonable；And riveting letter
Singly, air-tightness after reliable and stable, riveting is riveted high.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 3 to Fig. 5, in the present embodiment, a kind of reversely explosion-proof rivet includes blind rivet 20 and rivet nut 30, described
Rivet nut 30 includes nail body 31, and one end of the nail body 31 is provided with rivet nut shade 32, and the rivet nut shade 32 is oblate structure,
The blind rivet 20 includes assister bar 21, and one end of the assister bar 21 is extended with ailhead connecting portion 22, the ailhead connecting portion 22
On be extended with ailhead 23, the ailhead 23 is oblate structure, and the assister bar 21 and the ailhead connecting portion 22 connect
Place is provided with the wedge-shaped indentation 24 being broken for blind rivet, in the blind rivet 20 in wedge-shaped indentation 24 and the ailhead connecting portion 22 it
Between be provided with boss 25, the diameter of the boss 25 is more than the diameter of the assister bar 21, and the diameter of the assister bar 21 is more than
The diameter of the ailhead connecting portion 22.The ailhead 23 is coordinated to offer half-via 33 on the nail body 31, the blind rivet 20 is set
Put in one end insertion half-via 33 of ailhead 23 and ailhead 23 is stuck in half-via 33 by being molded, and the assister bar
21st, ailhead connecting portion 22 and the inwall close-fitting of wedge-shaped indentation 24 and half-via 33.
Refer to shown in Fig. 6 and Fig. 7, the direction of arrow represents pressure directions in Fig. 7, when in use, rivet nut 30 is put into and treated
In the endoporus of the first riveting riveting object 41 of object 40 and first of connection, the assister bar 21 in blind rivet 20 is then put into riveting gun
It is interior, pull during riveting gun because ailhead 23 is stuck in completely in half-via 33 and assister bar 21 with ailhead 23, ailhead connecting portion 22 is connected nothing
Method is moved, and can only be moved from nail body 31 under the effect of riveting gun power to the first riveting riveting object 41 of object 40 and first.When nail body
31 are moved to the power that the power produced after the laminating completely of riveting thing is more than at wedge-shaped indentation 24, and this point fracture, assister bar 21 is drawn out
Rivet nut 30 completes riveting.
After the completion of staking, ailhead 23 is stopped in situ, and it is rivet nut into original enclosed construction, gas that internal structure is not destroyed
Pressure can not penetrate riveting body.Reverse staking makes rivet nut shade 32 bear on the face of air pressure, and the riveting gun of conventional rivets can only be in cap
The staking at, such shade can not be on the face by air pressure.
Above example is the general principle and characteristic for elaborating the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
