Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, one embodiment provided by the present utility model is: the utility model provides an automatic stopping not hard up nut, including nut body 6, spring groove 5 has been seted up to outer wall one side of nut body 6, mounting hole 1 has been seted up to the inner wall upside of spring groove 5, the inside of mounting hole 1 is provided with curved wire spring 2, the one end fixedly connected with rolling cylinder 3 of curved wire spring 2, the outer wall setting of rolling cylinder 3 is at the inner wall of inclined plane groove 4, the lower surface at spring groove 5 is seted up to inclined plane groove 4, when locking nut body 6 clockwise rotation gradually, curved wire spring 2 also can produce little range rotation thereupon, apply elasticity to rolling cylinder 3, with rolling cylinder 3 push up the inclined plane all the time, then under the elasticity effect, rolling cylinder 3 has played the effect of wedge to inclined plane groove 4, along with the increase of the locking degree of nut body 6, the elasticity that curved wire spring 2 produced is increasingly, thereby make rolling cylinder 3 wedge the degree of inclined plane groove 4 increasingly, the locking friction is also increasingly greater, finally reach the function of automatic stopping, the setting of curved wire spring 2 can play the effect of fixed rolling cylinder 3 and not drop.
The upper end face of the inclined plane groove 4 is provided with a certain inclination, through being provided with certain inclined plane with the inclined plane groove 4 up end of this automatic stopping not loose nut body 6, it is low at nut body 6 tightening direction, high at nut body 6 loosening direction, thereby when using under the scene that vibration frequency is high, when nut body 6 is not hard up, receive the interior cylinder 3 wedge of rolling in inclined plane groove 4, thereby play the requirement of automatic stopping not loose, the outer wall sliding connection of rolling cylinder 3 is at the inner wall of inclined plane groove 4, nut body 6 is standard M20 nut, nut body 6's length is 32.95mm, nut body 6's width is 30mm, nut body 6's height is 19mm, nut body 6 is standard M24 nut, nut body 6's length is 39.55mm, nut body 6's width is 36mm, nut body 6's height is 22.3mm, nut body 6 is standard M30 nut, nut body 6's length is 50.85mm, nut body 6's width is 46mm, nut body 6's height is 26.4mm, nut body 6 includes but not limited to M20, M24 and M30.
Working principle: when the device is used, as shown in fig. 1, the nut body 6 is in an unlocked state, the curved steel wire spring 2 does not restrict the nut body 6, when the nut body 6 is locked gradually by rotating clockwise, as shown in fig. 2, the curved steel wire spring 2 also rotates by a small amplitude, the rolling cylinder 3 is applied with elastic force, the rolling cylinder 3 always pushes against an inclined plane, so that under the action of the elastic force, the rolling cylinder 3 plays a role of a wedge on the inclined plane groove 4, and as the locking degree of the nut body 6 is increased, the elastic force generated by the curved steel wire spring 2 is larger and larger, so that the degree of wedging the rolling cylinder 3 into the inclined plane groove 4 is larger and larger, and the anti-loosening friction force is larger and larger, and finally, the function of automatic stopping is achieved.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
