Safe and convenient threaded fastener assembly tool

Abstract

The invention discloses a safe and convenient threaded fastener assembly tool, which includes an outer cylinder, a supporting ring arranged in the inner cavity of the cylinder of the outer cylinder, a nut anti-rotation device, and a clasp; the safe and convenient threaded fastener of the present invention Assembling tools, by installing nuts, spring washers, and flat washers in one tool in advance, make them form a whole before installing the bolts, which solves the problem of flat washers, spring washers, and nuts in various occasions, at various angles, and at various angles. In this case, the problem of being scattered and falling during assembly is safe, efficient, convenient and fast, especially suitable for bolts that need to pass through the workpiece vertically from top to bottom, and flat washers, spring washers, and nuts that need to be threaded from bottom to top in sequence The situation of over-bolts; and can adapt to fasteners of different specifications, the applicability of the tool is good.

Description

technical field [0001] The invention relates to the technical field of fastener assembly tools, in particular to a safe and convenient threaded fastener assembly tool. Background technique [0002] At present, in the market, almost all the research on nuts is to consider how to make them fit on the bolts without loosening, so there are various ways to make them tighter, the most common and common one is nuts. The method is to add spring washers, and in order to increase the contact area between the nut and the workpiece, a flat washer is generally used, and the spring washer is located between the flat washer and the nut. [0003] The flat washer, the spring washer and the nut are three independent parts, which pass through the bolt in turn, and then the three are firmly fixed on the bolt by tightening the nut. During the screwing process, the bolt head usually also needs to be held in place by the tool. In this way, during operation, the operator fixes the head of the bol...

AI Technical Summary

Problems solved by technology

like Figure 16 As shown, when the bolt 9 is required to vertically pass through the workpiece 10 from top to bottom, the flat washer 6, spring washer 7, and nut 8 need to pass through the bolt from bottom to top in sequence. The two parts are separated. For the operator, it is more difficult to grasp these three parts at the same time with one hand. In addition, due to the effect of gravity, after the flat pad 6 and the spring pad 7 are put on the bolt 9, they can be removed and assembled. And if the nut 8 is pre-tightened, the flat washer 6 and spring washer 7 will easily fall off

If the operating space is narrow, it will be very laborious and must be picked up continuously; or, if it is operated at high altitude, it is very easy to become a falling object, and there is a high potential safety hazard

[0005] The tools currently on the market, almost all consider how to tighten the nuts, such as block wrenches, socket wrenches, ratchet wrenches, adjustable wrenches, etc., all of which only consider the problem of tightening the nuts, and do not consider how to tighten the three nuts. One (flat washer, spring washer, nut) or both (flat washer, nut) for convenient and safe operation
