Abstract
The utility model relates to a novel bolt and nut locking structure. A radial groove similar to the shape of a radial gasket is manufactured on the bottom surface of a locking nut, a vertical groove parallel to the axis thereof in the circumferential direction is manufactured on the outer side surface of a fastening nut, and the vertical groove is connected with a bolt by the fastening nut; then, the radial gasket is sheathed on a protruding bolt on the fastening bolt, the locking nut is installed on the protruding bolt at the upper part of the radial gasket, and the radial groove at the bottom part of the locking nut is downward. When the locking nut is close to the radial gasket, the radial gasket is clamped in the radial groove at the bottom part of the locking nut, and the locking nut is continued to be screwed down, so as to lead a radial branch of the radial gasket to be right aligned with the vertical groove on the outer side surface of the fastening nut; finally, the radial branch of the radial gasket is embedded in the vertical groove on the outer side surface of the fastening nut after being bent.
Description
Technical field
The utility model relates to the locking mechanism of a kind of locking mechanism of bolts and nuts, particularly a kind of novel bolts and nuts, belongs to mechanical connection and locking technical field.
Background technique
In machinery; the connection overwhelming majority between the part moved screw thread and realizes being connected with nut; but, because machinery can produce certain vibrations in the process of operation; so; after using after a while, usually can produce lax phenomenon thus between the bolts and nuts, once the generation of this situation; just might make the equipment can't proper functioning, even cause other great security incident.
In order to overcome the relaxation phenomenon that occurs between the bolts and nuts, at present, some bolts and nuts locking mechanisms and locking mode arise at the historic moment, though the locking mechanism of these bolts and nuts has solved corresponding problem to a certain extent, but, also have some defectives.
The model utility content
The purpose of this utility model is: a kind of locking mechanism of novel bolts and nuts is provided, overcomes existing more existing defectives of bolts and nuts locking mechanism.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: a kind of locking mechanism of novel bolts and nuts, and it is made up of bolt, Merger jack panel, radial packing ring, tightening nut; Locking mechanism You Yi Merger jack panel has the bottom surface of Merger jack panel the similar radial groove of one washer-shaped that produce and radial, the outer side surface of tightening nut have one produce in the equal portion of circumferencial direction, vertical groove with self parallel axes, be connected with bolt with tightening nut, make and form the relation that is fastenedly connected between bolt and the tightening nut, then radial gasket sleeve is contained in downward of bottom radial groove that Merger jack panel above the bolt outstanding on the clamping bolt is installed in Merger jack panel above the outstanding bolt in radial packing ring top Dang the Merger jack panel during near radial packing ring, in the radial groove with radial packing ring engaging Zai Merger jack panel bottom, and continuation Ning Jin Merger jack panel, and the radial branch of radial packing ring and the vertical groove of tightening nut outer side surface are aligned, the radial branch bending of radial packing ring is crouched in the vertical groove of tightening nut outer side surface.
Beneficial effect: the utility model is owing to limit by the degrees of freedom of circumferentially mutually rotating of radial packing ring Jiang Merger jack panel and tightening nut, so, can reach the purpose of locking, simultaneously, the utlity model has simple in structure, the advantage of installation, convenient disassembly.
