Two kinds of different screw threads (the conventional screw thread on unconventional screw thread in tapered on the enlarging wall and the straight tube inwall) can be implemented relative priority processing from its two ends in the described special nut 2; And; Guarantee the height H of above-mentioned driving fit contact segment, promptly the screw thread of the height H scope of conventional helical thread portion can contact with the driving fit turn that the screw thread of conventional bolt 1 is implemented any relative position.---obviously: the requirement of the binding site of the screw thread on the unconventional tapered interior enlarging wall of conventional screw thread on special nut 2 inwalls and special nut 2 is:
Conventional screw thread on described special nut 2 inwalls must be complete; Can let conventional bolt 1 pass through from above-mentioned binding site precession; And screw thread on the enlarging wall can be incomplete on above-mentioned binding site position in special nut 2 unconventional tapered, promptly there is no need to let this unconventional tapered in screw thread on enlarging wall must be identical each other with the conventional screw thread on special nut 2 inwalls; So require in use can not influence the precession of slope shape loosening-proof jump ring K;---generally; To the design of slope shape loosening-proof jump ring K the time; Be easy to just can to accomplish not allow the position of the conventional screw thread on most advanced and sophisticated precession to above-mentioned special nut 2 inwalls of slope shape loosening-proof jump ring K, promptly be easy to let the tip of slope shape loosening-proof jump ring K can't arrive the binding site position of above-mentioned two kinds of screw threads;
The described material hardness that is provided with the slope shape loosening-proof jump ring K of embedded wedge angle P should be greater than the material hardness of bolt 1; It can reach the requirement that it improves hardness through the heat treatment that increases its hardness again through through sheet metal punching press shear forming in batches simultaneously;---guarantee that the embedded wedge angle P on the above-mentioned slope shape loosening-proof jump ring K can embed in the metal threaded trench in (penetrating) conventional bolt 1 slightly under the compressing of external force, and such " embedding (penetrating) " is as long as the degree of " a little " that reaches is just passable;
The riveting parts that described screw bolt-type rivet is implemented receives external influence and shakes severely; Impel the dynamics of special nut 2 counterrotating displacements (desiring to withdraw from the dynamics of conventional bolt 1) just big; Yet; Because the existence of slope shape loosening-proof jump ring K stops the dynamics of special nut 2 counterrotating displacements also big through the gradient on the slope shape loosening-proof jump ring K; Simultaneously: special nut 2 is also big by the dynamics that slope shape loosening-proof jump ring K blocks; The dynamics that compressing this moment embeds the embedded wedge angle P in (penetrating) conventional bolt 1 is also big; And this dynamics has stoped the relative displacement of slope shape loosening-proof jump ring K in conventional bolt 1 screw thread trench forcefully; This slope shape loosening-proof jump ring K can not be subjected to displacement, and has just stoped special nut 2 to get loose the displacement of trend yet;
The section included angle B of described slope shape loosening-proof jump ring K bottom should be less than the section included angle A of thread groove two walls in the conventional bolt 1;---guarantee that the embedded wedge angle P on the above-mentioned slope shape loosening-proof jump ring K can embed in the metal threaded trench in (penetrating) conventional bolt 1; This just need let has certain gap, the left and right sides (move place) in the metal threaded trench of this slope shape loosening-proof jump ring K in conventional bolt 1; After embedded wedge angle P embedded the metal threaded trench in (penetrating) conventional bolt 1, whole slope shape loosening-proof jump ring K had promptly been lived by final location;
The total height of described special nut 2 is made up of the height V of the tapered interior flared part of both height H through conventional threaded closure contact segment of conventional bolt 1 and special nut 2 and increase; And, this height H should with 1 on conventional bolt require total height (total thickness) that the plain nut of adapted has should be identical (making the NBS that pulling force meets same diameter bolt and adapted nut of bearing of screw bolt-type rivet of the present invention require);---the value ratio of the height V of the height H of above-mentioned conventional threaded closure contact segment and above-mentioned tapered interior flared part is preferably 2:1.
When using the present invention to carry out " riveted joint ", the method when promptly the following plate 4 of the last plate 3 of the workpiece among Fig. 1 and workpiece being carried out " riveted joint ":
A. at first, conventional bolt 1 and special nut 2 are tightened on according to the method for routine above the following plate 4 of last plate 3 and workpiece of the workpiece that needs riveted according to the signal of Fig. 1;
B. then, slope shape loosening-proof jump ring K is embedded in the thread gaps of above-mentioned conventional bolt 1 and special nut 2 according to the signal of Fig. 1 again;
C. the mode that after, the slope shape loosening-proof jump ring K in the thread gaps that is embedded in above-mentioned conventional bolt 1 and special nut 2 is locked at wherein (for example: utilize hammer to aim at the mode that this slope shape loosening-proof jump ring K afterbody knocks through nail and implement the locking process) lets this slope shape loosening-proof jump ring K be in the embedding state that can not become flexible;---under slope shape loosening-proof jump ring K can not fall back the prerequisite of displacement, then special nut 2 will be propped up by the domatic inclined-plane of this slope shape loosening-proof jump ring K: this special nut 2 was desired backspin (getting loose), will got tight by this domatic inclined-plane card;
D. last; With the special nut 2 of common spanner backspin (although almost revolving motionless), force to be arranged on slope shape loosening-proof jump ring K and to go up in the thread groove that hard and sharp hard and sharp embedding wedge angle P that its hardness is higher than conventional bolt 1 pricks into conventional bolt 1 (if feel oppositely firmly to revolve but revolve motionless get final product---felt reverse turn significantly then explained that " c " money program not necessarily meets the requirements---obviously the locking degree of " c " money is preferably confirmed through relevant conventional mechanical or the dynamo-electric special-purpose measurer instrument of holding concurrently of locking).---the last the most key action that utilizes the special nut 2 of common wrench application of force backspin; With " riveted joint " program of accomplishing the screw bolt-type rivet (letting above-mentioned embedding wedge angle P prick in the thread groove of into conventional bolt 1); Promptly prevent slope shape loosening-proof jump ring K that " riveted joint " program of " displacement of falling back property " takes place; Obviously be that micro-plasticity and the elastically-deformable characteristics of having utilized the metal that constitutes the screw bolt-type rivet to have realize; And make the mechanically stressed amplification of should trace deformation accomplishing common saying described " art is good for strength ", promptly form powerful " riveted joint " fastening effect between the conventional bolt 1 that constitutes the screw bolt-type rivet and the special nut 2.
