Abstract

The invention relates to a double-raised-head slope-shaped loosening-proof clamp spring with a rivet function screw component, which is based on the technology of CN100398848C. The double-raised-head slope-shaped loosening-proof clamp spring with a rivet function screw component is characterized in that a single-raised-head slope-shaped loosening-proof clamp spring (K) is lengthened from the rear part, a second raised head which is used for assisting to exit the slope-shaped loosening-proof clamp spring (K) is also arranged at a distance (L) from an anti-skidding closed angle (P) serving as the first raised head of the aftermost part so as to form the double-raised-head slope-shaped loosening-proof clamp spring; and the protruding direction of the second raised head (T) on the clamp spring is different from that of the anti-skidding closed angle (P). A magnetic propelling and screwing special tool absorbs the double-raised-head slope-shaped loosening-proof clamp spring and embeds and positions the double-raised-head slope-shaped loosening-proof clamp spring in the screw component; and a magnetic dismantling special tool screws out the double-raised-head slope-shaped loosening-proof clamp spring and absorbs and sticks out. If the reverse out-screwing force of a nut (2) is used after the double-raised-head slope-shaped loosening-proof clamp spring (K) is propelled and screwed so that the anti-skidding closed angle (P) acts to form a permanently dismountable normal rivet, the dismounting special tool is useless.

Description

Biconvex slope shape loosening-proof jump ring and using method thereof with rivet function screw assembly

Technical field

The present invention relates to a kind of biconvex slope shape loosening-proof jump ring and using method thereof with rivet function screw assembly.

Background technique

Various steel structure in the middle of the general big-and-middle-sized engineering (for example: the roof of bridge and Bird's Nest), all can't do without this fastening piece that becomes flexible never of rivet under strong frequent vibration.Its deficiency is: be difficult to the high-altitude site operation more than ground, usually must burn on ground and can forge the process finish medium-and-large-sized riveted joint of beating to metalwork after red, domestic and international go-go building or extra-high-speed building often also all are to need to adopt the form moulding of steel frame construction riveted joint can obtain maximum " cost performance " and the fastest construction speed.---allowing riveting process directly finish at the scene more than ground, is that people manage the problem that solves always.

CN100398848C (ZL200310108707.6) has disclosed a kind of substitute products of screw assembly snap riveting nail.

Summary of the invention

The present invention's purpose: be on the basis of CN100398848C technology, by the architecture advances of one of them critical component " slope shape loosening-proof jump ring ", widen its whole using scope with rivet function screw assembly.

Key of the present invention is: increase to be provided with as " second plush copper " with another function at this " slope shape loosening-proof jump ring " existing anti-skidding wedge angle " plush copper " architecture basics and realize the object of the invention seeing the introduction in " embodiment " for details.

The present invention's characteristics compared with the prior art: mainly be the comparison characteristics with CN100398848C patent of invention technology, make structure of the present invention possess following characteristics in the use: can be according to different needs, can either realize the using method of permanent " non-dismountable " (have the antivibration function with equal " non-dismountable " of existing rivet---increase the program that allows the nut backspin exert oneself during use and allow anti-skidding wedge angle play a role), also can realize " detachably " using method of (ability of antivibration slightly is worse than the locking degree of above-mentioned " non-dismountable "---do not increase the program that allows the nut backspin exert oneself during use and do not allow anti-skidding wedge angle play a role).

Description of drawings:

Fig. 1 has illustrated to relate to and has replaced the working state of rivet when fastening; Fig. 2 has illustrated the structure of profile of the present invention when deployed condition; Fig. 3 is the left side view of Fig. 2; Fig. 4 is the D-D agent face figure of Fig. 2.

1: bolt; 2: nut; 3: engineering part A; 4: engineering part B; K: slope shape loosening-proof jump ring; P: anti-skidding wedge angle (first plush copper); T: second plush copper; L: the distance between anti-skidding wedge angle rear portion and second plush copper; H: with the nut thread size of the meshing GB of bolt regulation; Q: additionally increase part; A: bolt thread groove angle; B: retaining jump ring bottom section angle.

Embodiment

Have: its tail end bottom has single plush copper slope shape loosening-proof jump ring K of an anti-skidding wedge angle P at least, it is characterized in that:

Lengthen above-mentioned single plush copper slope shape loosening-proof jump ring K from its rear portion, and locate and be provided with at least one in order to assist having the second plush copper T that withdraws from this slope shape loosening-proof jump ring K the rivet function screw assembly (be specifically designed to slope shape loosening-proof jump ring K is oppositely moved with the hand---withdraw from the origin-location) from above-mentioned leaving the rear portion distance L of this aftermost anti-skidding wedge angle P (this L be in the bolt 12 to 5 times of pitch or bigger), make it to become a biconvex slope shape loosening-proof jump ring K.And: the material hardness of this biconvex of A. retaining jump ring K is greater than the material hardness of bolt 1; B. the section angle b of this biconvex retaining jump ring K bottom is less than the section angle a of bolt 1 thread groove two walls.

The projected direction of the second above-mentioned plush copper T on this biconvex retaining jump ring K is different with the protrusion direction of anti-skidding wedge angle P, and the two preferably is 90 degree angles (should be the optimum position) or 180 degree angles.

Between the nut 2 taper enlarging screw threads and bolt 1 screw thread of an above-mentioned biconvex retaining jump ring K beyond nut thread size H.

Screw assembly tool the present invention is arranged on after by the absorption pushing in the middle of the technical pattern of CN100398848C if advanced by special-purpose magnetic, namely between Chang Gui bolt 1 and the special nut 2, then, backspin withdraws from above-mentioned special tool again, after again nut 2 reverse backspins being exerted oneself at last, will bring into play anti-skidding wedge angle P and prick retaining usefulness in bolt 1 groove into, the structural type of the screw assembly snap riveting nail that allows this pair of bolts 1 and nut 2 form forever can't to dismantle and can realize the assembled in situ construction.

Yet, after the present invention is pushed between the bolt 1 that is tightened on above-mentioned routine and the special nut 2, if the backspin nut 2, namely allow anti-skidding wedge angle P not play a role, when needing later on, just can adopt the second plush copper T on magnetic removal tool special (having special-purpose key effect) the derotation pulling biconvex slope shape loosening-proof jump ring K, be it can be withdrawed between above-mentioned bolt 1 and nut 2, formation widen function using method (be preferably in nut 2 extra increase part Q is arranged in shape this moment---for increase " lockset " and function creates conditions), namely allow bolt 1 and the special nut 2 of this a pair of routine form the volatile standard " rivet " of band " lock ".
