Description

The present invention relates to a device for preventing the nut from being unscrewing, using a protrusion having two cuts screwed inside the inside and being grasped by a face ring that is put on it, which can turn the protrusion against the cutting of the bolt by turning, by selecting the slack injected by the cuts.

In FIG. 1 shows separately a nut with a protrusion in front of FIG. 2-above; FIG. 3 on the side of FIG. 4 and 4-in two fractions of a faceted ring; FIG. 5 and S-in two projections nut with ring assembled; FIG. 6 - in two projections a restrictive spike.

The fixture is as follows: the nut 1 (Figs. 1, 2, 3) carries on itself a protrusion 1st screwed inside, which, due to two notches-transverse non-through Ih and fractional through-it, has some slack in relation to the bolt passing through it. Outside, the protrusion 1d is provided with two flats 2b, 2b. The faceted ring 2 (Fig. 4 and 4), which encircles the shoulder. 1d, also has internal flats 2 / :, 2c, matching the flips 2 /, and a cutout 2a, limiting the angle of rotation of the ring. In assembled form (Figs. 5 and 5), the ring 2 is secured from disconnection from the nut 1 with the corresponding shoulder at the end of the projection-1d. ,

If desired, lock the ring 2 nut to the position shown by the conditional dotted line in FIG. 5, so that the edge Id of the ring 2 takes the place, which rotation will destroy the slacks 2c by the flat ends 2c, and cuts the latter to cutting the bolt, preventing the unscrewing of the nut. The required angle of rotation is provided by the presence of the spike 3 (Fig. 6) inserted into the body of the nut 1, into which the spike, in the extreme positions, abut the walls of the notch 2a of the ring 2.

The subject of the patent. ,

A device that prevents the unscrewing of the nut, which is characterized by application on the nut 1 (Fig 1-3) screwed inside the protrusion 1l with two cuts-transverse non-through 1 / and share

through 1c and two outer coats 2 / J, 1, which protuberance is wrapped around a naked ring 2 with two inner coats, 2e, 2c, corresponding to the flies 2 &

in order to press the protrusion by the indicated Hysky 2c to the cutting of the bolt in order to prevent the nut from unscrewing, at 4feM the rotation of the ring 2 is limited by a spike 3, the entrance of the ring into the corresponding cutout in the ring 2.
