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
The present invention relates to a kind of anticreep method of nut, especially relate to a kind of left-handed and dextrorotation double nut and snap into the as a whole a kind of left-handed and dextrorotation double nut buckle that prevents that nut loosening from coming off and prevent the method that nut loosening comes off.
Background technique
The component such as set screw, bearing, since invention, obtained using widely, but the problem of the easy loose or dislocation of nut that plays fixation of twisting on its end thread is solved always thoroughly, and this deficiency has seriously influenced stability and the reliability of the equipment that has used these parts.Therefore, design a kind of new method that prevents that nut loosening from coming off and become a kind of current demand.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, provide a kind of and prevent that nut a kind of left-handed and dextrorotation double nut of loose or dislocation from the bolt from snapping into the as a whole a kind of left-handed and dextrorotation double nut buckle that prevents that nut loosening from coming off and preventing the method that nut loosening comes off.
The present invention realizes in the following way:
A kind of left-handed and dextrorotation double nut buckle prevent the method that nut loosening comes off, it is characterized in that: the method is on two nuts of left-handed and dextrorotation of twisting at the same bolt that is distributed with the two screw threads of left-right rotary, be distributed with convex Ka Jiao or concavity draw-in groove, and when left-handed and two nut screwing clampings of dextrorotation, the Ka Jiao on one of them nut can stick in the draw-in groove on another nut;
Described Ka Jiao or draw-in groove are distributed on the side that nut is in contact with one another;
All be distributed with the dentation Ka Jiao that is extended laterally by the inboard on the side that is in contact with one another of above-mentioned two nuts, two concavity gaps of blocking between the angle consist of draw-in groove;
Described Ka Jiao or draw-in groove are distributed on the surface that rib is arranged of two nuts;
All be distributed with Ka Jiao on the surface that rib is arranged of described two nuts, after double nut is tightened two Ka Jiao be screwed in together;
Described two nuts not only are distributed with Ka Jiao or draw-in groove on its side that is in contact with one another, and also distribute on the surface of rib Ka Jiao or draw-in groove are arranged.
The present invention has following effect:
Because in the present invention, left-handed is to be screwed on the same nut that is distributed with the two screw threads of left-right rotary with double nut dextrorotation, Ka Jiao sticks in the draw-in groove because material has elastic energy when fastening nut, behind nut screwing clamping, has certain plasticity because of material again, Ka Jiao has certain distortion, it is more firm that this distortion can make two nut buckles get, and become as a whole, its effect is exactly that the not loosening of left-right rotary double nut combination do not come off the problem that has easily got loose with regard to having solved theoretically existing nut like this.

Embodiment
Embodiment one: a kind of left-handed and dextrorotation double nut buckle prevent the method that nut loosening comes off, the method is: the same bolt that is distributed with the two screw threads of left-right rotary screw on match with it the left-right rotary double nut, on the side 1 that the left-right rotary double nut is in contact with one another, as illustrated in fig. 1 and 2, be distributed with concavity draw-in groove 2 or convex card angle 2, with two nut screwing clampings and note making a card angle 2 on the nut to stick in the draw-in groove 2 on another nut getting final product.
Embodiment two: a kind of left-handed and dextrorotation double nut buckle prevent the method that nut loosening comes off, the method is: the same bolt that is distributed with the two screw threads of left-right rotary screw on match with it the left-right rotary double nut, on the side 1 that the left-right rotary double nut is in contact with one another, as shown in Figure 3, all be distributed with the dentation card angle 2 of being extended laterally by the inboard, with two nut screwing clampings and note making a card angle 2 on the nut side to stick in the spaces between two card angles on another nut getting final product.
Embodiment three: a kind of left-handed and dextrorotation double nut buckle prevent the method that nut loosening comes off, the method is: the same bolt that is distributed with the two screw threads of left-right rotary screw on match with it the left-right rotary double nut, having on the edge surface 1 of left and right sides double nut, as shown in Figure 4 and Figure 5, be distributed with card angle 2 or draw-in groove 2, with two nut screwing clampings, as block the angle front end to the inside hook-shaped bending is arranged, then when tightening, note making a hook-shaped curved end in card angle on the nut to stick in the draw-in groove on another nut and get final product; As block angle front end Wugou sigmoid, then execute external force and Ka Jiao is sticked in the draw-in groove on another nut get final product.
Embodiment four: a kind of left-handed and dextrorotation double nut buckle prevent the method that nut loosening comes off, the method is: the same bolt that is distributed with the two screw threads of left-right rotary screw on match with it the left-right rotary double nut, having on the edge surface 1 of left and right sides double nut, as shown in Figure 4, all be distributed with card angle 2, be screwed in together with two nut screwing clampings and with the Ka Jiao on two nuts and get final product.
