Embodiment Construction

[0024] Position the bolt (1) on the engineering part A (3) and the engineering part B (4), tighten the nut (2) on the bolt (1) as usual, and then place the semi-circular bar shape with a slight slope Screw in the anti-retraction retaining ring (K) from the threaded tapered gap between the bolt (1) and the nut (2). Finally, borrow the special tool screwed in with the bolt (1) to screw the anti-retraction retaining spring ( K) Rotate and press inward. Alternatively, it is also feasible to use nails and hammers to tighten the stop jumper (K) inwardly. This is another simpler but more cumbersome operation scheme for tightening the nut (2). After that, turn the nut (2) slightly in the direction of unscrewing (objectively, it is impossible to increase the anti-rotation range), so that the anti-slip sharp corner ( P) Dig slightly into the thread groove of the bolt (1).

[0025] It is not difficult to find out from all accompanying drawings, after this, it is impossible to unscrew t...

Abstract

The present invention provides a screw module with rivet function and sloped nut backstop jump ring and its usage. The screw module includes at least screw, nut and backstop jump ring set in the gap of threads and with antiskid tip, and may be located with some tool in where rivet is originally needed. The present invention is suitable for non-detachable connection and reinforcement in engineering member, and is especially suitable for replacing rivet in large engineering member to facilitate the in-situ construction.

Description

Technical field: [0001] The present invention relates to fastener technology and methods of use thereof. Background technique: [0002] At present, the "screw-nut" type fasteners on the market are all equipped with nuts that can be advanced (tightened) and retracted (loosen) on the bolts. The washer can play a certain anti-retreat effect on the tightened nut, but when the nut is turned with a strong force (in fact, a little more force), the nut will still be loosened and withdraw from the bolt. [0003] Therefore, the existing "screw-nut" type fasteners do not have the function of rivet riveting (non-detachable) related parts, unless after the nut is tightened on the bolt, the nut and the nut are welded together by metal welding. The bolts are welded on. This just can play anti-retreat effect to the nut that arbitrarily tightens, yet this can bring inconvenience to construction operation naturally. [0004] For this reason, when building large or giant non-detachable stee...
