Specific embodiment
For the content for further appreciating that the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.
Embodiment
In conjunction with Fig. 2, the surface of a kind of novel twin-lock rivet of the present embodiment, including rivet body and blind rivet, rivet body and blind rivet is equal
It is provided with Corrosion Protection of Fiber Reinforced Plastics layer, has good resistivity to big gas and water and a variety of acid, alkali, salt and a variety of organic solvents,
It is able to extend the service life of twin-lock rivet, it is very practical；Rivet body includes straight shape sleeve 11 and is integrally provided on sleeve 11
The head of a nail 12 of lower end, blind rivet is structure as a whole, and blind rivet is by the latch section 21 with annular latch sequentially connected from front to back, use
Be pressed into the snap ring 22 of sleeve 11, the first light bar segment 23, the locked groove 24 to lock rivet body, the second light bar segment 25, disconnected power slot 26,
Third light bar segment 27 is formed with the raw silk rings section 28 of rivet body interference fit and tail portion kerve section 29, and the outer diameter of snap ring 22 is greater than
The internal diameter of sleeve 11, and the outer diameter of snap ring 22 is less than the outer diameter of sleeve 11；The upper end outer edge of sleeve 11 is set
It is equipped with cut-protection fillet 112, prevents from being accidentally injured by the upper end outer edge of sleeve 11；First is provided at the inner hole upper end of sleeve 11 to fall
Angle 111, simple in sturcture, ingenious in design, when rivet body and blind rivet, the positioning under the effect of raw silk rings section assembles snap ring when finishing and is against first
On the inclined-plane of chamfering, when riveting machine staking, snap ring enters in straight shape sleeve along inclined-plane, so that straight shape sleeve is heaved, realizes riveting
Purpose is connect, it is easy to use；In the inner hole of sleeve 11 and it is located at that 111 lower section of the first chamfering is axially disposed there are multiple annular grooves 13, and
The lower port of each annular groove 13 is provided with the second chamfering 131, is heaved when snap ring enters after sleeve in straight shape sleeve, due to annular groove
Presence so that straight shape sleeve is heaved more convenient, and the downside of snap ring and annular groove offsets, the effect on the second chamfering inclined-plane
Under, it goes successively in straight shape sleeve straight shape sleeve be heaved along inclined-plane, riveting is more convenient, and is squeezed forward end in snap ring
Latch section after, in latch section be located at snap ring below annular slot can mutually block with the annular groove in undeformed section in straight shape sleeve
It closes, so that riveting is more firm；Angle between the upper surface of the intracorporal locking step 14 of riveting and the side of rivet body inner hole is sharp
Angle has had more a part of filler material for right angle locking step, and locking step and locking slot will have more one when locking
Point filler material is squeezed into locking slot, guarantee locking slot be not it is empty, improve the anti-seismic performance of twin-lock rivet.
Riveting machine plays when use, and lobe clamps tail portion kerve section, and blind rivet is driven to move backward, and riveting machine housing is opposite to be followed closely
Core travels forward, and presses to rivet body head, in the sleeve that snap ring is caught in rivet body under the action of the first chamfering inclined-plane, so that riveting
The straight shape sleeve of body is heaved, and blind rivet continuation moves backward, since the presence of annular groove and the second chamfering makes the straight shape sleeve side of heaving
Just, when straight shape sleeve swells card on the steel plate when, blind rivet continuation move backward, snap ring is squeezed forward end under the action of steel plate
Latch section, blind rivet continuation move backward, latch section mutually blocks cooperation with annular groove, and the locked groove of blind rivet compresses under the action of riveting machine
On rivet body internal locking step, blind rivet is broken at disconnected power slot, completes riveting work (participating in shown in Fig. 3).
A kind of novel twin-lock rivet of the utility model, it is simple in sturcture, ingenious in design, it can be ensured that realize the mesh of double internal locks
, riveting is convenient, and riveting is secured, and long service life.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
