Double-raised-head slope-shaped loosening-proof clamp spring with rivet function screw component and using method thereof

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

technical field [0001] The invention relates to a double-convex slope-shaped anti-retreat clip spring with a rivet function screw assembly and a use method thereof. Background technique [0002] All kinds of steel structures in general large and medium-sized projects (such as the roof of bridges and bird's nests) are indispensable for fasteners such as rivets that will never loosen under strong and frequent vibrations. Its shortcoming is that it is difficult to construct on-site at high altitudes above the ground. Usually, the metal parts must be burnt red before the metal parts can be forged to complete the process of medium and large riveting. The most modern buildings or super high buildings at home and abroad are often It needs to be formed in the form of riveting steel frame structure to get the greatest "cost performance" and the fastest construction speed. ——It is a problem that people have been trying to solve to make the riveting process can be directly completed o...
