Quick tightening wrench applied to interlocking double nuts

Abstract

The invention provides a quick tightening wrench applied to interlocking double nuts. A driving bevel gear, a driven bevel gear, a rotation direction adjusting rod, a ratchet wheel, a pawl, a cam, anouter shell and a handle are included; according to the quick tightening wrench applied to the interlocking double nuts, a main nut is tightened through small teeth on the outer shell, a locking nut is tightened through teeth in the driven bevel gear, and it is achieved that the two nuts are tightened at the same time; according to the quick tightening wrench applied to the interlocking double nuts, a ratchet mechanism is fully utilized; by adjusting the direction of the rotation direction adjusting rod, when the double nuts are screwed too tightly and difficult to take down, the rotation direction adjusting rod of the wrench can be shifted to the opposite direction, and then the handle is rotated by a certain angle to the opposite direction of the previous tightening direction, so that the handle can be smoothly taken down; and the tightening speed of the double nuts is effectively increased, the operation efficiency by a worker is effectively improved, and the quick tightening wrenchapplied to the interlocking double nuts is more convenient and safer for workers in high-altitude operation.

Description

technical field [0001] The invention relates to the field of mechanical wrenches, in particular to a quick tightening wrench applied to interlocking double nuts. Background technique [0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. [0003] At present, there are many interlocking double nuts on the market. The working principle is mainly to use the structural interlocking between the two nuts to achieve the anti-loosening effect. The tightening process of some interlocking nuts is that the two nuts are first tightened clockwise to reach the standard. Tighten the torque, then fix one of the nuts and then reversely tighten the other nut. However, there is currently no fast tightening wrench specifically for this nut on the market to help construction workers tighten the nut quickly, improve work efficienc...

Problems solved by technology

[0005] The technical problem to be solved by the present invention: there are many interlocking nuts on the market. For this kind of nuts, the existing tightening method is mainly to use two wrenches to tighten at the same time and then use a general wrench to fix one of the nuts, and then use the other wrench to tighten the nut. Reverse rotation to tighten the other nut. This method of tightening with two wrenches is cumbersome, slow, and low in work efficiency; moreover, after searching, the publication number CN108058120A, the publication date 2018.5.22 discloses a The fast tightening wrench with double nuts uses a one-way clutch to ensure that the turbine can only move downward in the vertical direction, but the one-way clutch cannot change direction. If the double nuts are tightened too tightly, the wrench will not be easy to remove , the application is more limited
