Embodiment 1

[0018] Embodiment 1: A method for buckling left-handed and right-handed double nuts to prevent nuts from loosening and falling off. The method is: on the same bolt with left-handed double-threaded threads, the matching left-handed double nuts are screwed on. On the side 1 where the left and right double nuts are in contact with each other, such as figure 1 and 2 As shown, there are concave clamping grooves 2 or convex clamping angles 2 distributed. Tighten the two nuts and pay attention to make the clamping angle 2 on one nut fit into the clamping groove 2 on the other nut.

Embodiment 2

[0019] Embodiment 2: A kind of left-handed and right-handed double-nut fastening method to prevent the nut from loosening and falling off, the method is: on the same bolt with left-handed double-threaded thread, screw on the corresponding left-handed double-nut, On the side 1 where the left and right double nuts are in contact with each other, such as image 3 As shown, there are toothed corners 2 extending from the inside to the outside. Tighten the two nuts and pay attention to make the corners 2 on the side of one nut fit into the gap between the two corners on the other nut. That's it.

Embodiment 3

[0020] Embodiment 3: A method for buckling left-handed and right-handed double nuts to prevent nuts from loosening and falling off. The method is: on the same bolt with left-handed double-threaded threads, the corresponding left-handed double nuts are screwed on. On the ribbed surface 1 of the left and right double nuts, such as Figure 4 and Figure 5 As shown, there are snap angles 2 or snap slots 2. Tighten the two nuts. If the front end of the snap angle has a hook-shaped bend inward, pay attention to make the hook-shaped bent end of one nut clip into the other when tightening. Just put it in the groove on one nut; if there is no hook-like bend at the front end of the corner, apply an external force to make the corner snap into the groove on the other nut.

Abstract

The invention relates to a method for preventing nuts from falling off, in particular to a method for preventing nuts from being loosened and falling off by buckling a left-handed nut and a right-handed nut into a whole. The method comprises the following steps: convex clamping corners or concave clamping grooves are distributed on a left-handed nut and a right-handed nut which are screwed on the same bolt on which left-handed threads and right-handed threads are distributed, and when the left-handed nut and the right-handed nut are screwed up, the clamping corners on one of the left-handed nut and the right-handed nut are clamped into the clamping grooves on the other nut. The provided method can prevent the nuts from being loosened and falling off from the bolt by buckling the left-handed nut and the right-handed nut into a whole.

Description

technical field [0001] The invention relates to an anti-loosening method for nuts, in particular to a method for preventing nuts from loosening and falling off by buckling left-handed and right-handed double nuts as a whole to prevent nuts from loosening and falling off. Background technique [0002] Parts such as fixing screws and bearings have been widely used since their invention, but the problem that the nuts that are screwed on the end threads and play a fixing role are easy to loosen and fall off has not been completely solved. This problem has seriously affected the Stability and reliability of equipment using the part. Therefore, designing a new method for preventing the nut from loosening and falling off becomes a practical demand. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, to provide a kind of left-handed and right-handed double nuts that prevent the nuts from loosening and falling of...
