Abstract

The invention discloses a novel locking device of a bolt and a nut; a radial groove is formed on the bottom surface of a tightening nut and the shape of the radial groove is similar to that of a radial gasket, a vertical groove is formed outside the tightening nut and is uniformly distributed in the peripheral direction and parallel to the axis of the vertical groove, the vertical groove is connected with the bolt by the tightening nut, the radial gasket is then sleeved on the protruded bolt of a fastening bolt, the tightening nut is arranged on the protruded bolt at the upper part of the radial gasket, the radial groove at the bottom of the tightening nut faces downwards, when the tightening nut approaches the radial gasket, the radical gasket is clamped in the radial groove at the bottom of the tightening nut and then the tightening nut is continuously screwed, radial wattles of the radial gasket are enabled to be aligned to the vertical groove on the outside surface of the tightening nut, and the radial wattles of the radial gasket are enabled to be bended and lie in the vertical groove on the outside surface of the tightening nut.

Description

A kind of locking device of novel bolts and nuts

Technical field

The present invention relates to the locking device of a kind of locking device of bolts and nuts, particularly a kind of novel bolts and nuts, belong 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, still; 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.

Summary of the invention

The objective of the invention is to: a kind of locking device of novel bolts and nuts is provided, overcomes existing more existing defectives of bolts and nuts locking device.

The invention achieves the above objects the technology program are: a new bolt and nut locking device, it is by bolts, nuts Merger, radial washers, nuts composed; locking mechanism has a nut Merger will Merger of the bottom surface of the nut has a radially manufacture gaskets with radial grooves of similar shape, the outer surface of the fastening nut has a manufactured both in the circumferential direction of the portion, with its axis parallel to the vertical grooves, the fastening Nuts and bolts connected to the bolt and tighten the connection between the fastening nut relations, followed suit in the washer radially projecting bolt fastening bolts above the Merger nut mounted on the upper part projecting radially gasket bolt above the Merger tight nut at the bottom of radial grooves down, when Merger nut close radial gasket when radial gasket engaging in the Merger nut at the bottom of the radial groove and continue to tighten the Merger nut and make radial gasket radial branches with tight a vertical outer side on the nut recesses on the positive, the washer radially bent branches lying radially outer surface of the fastening nut of the vertical groove.

Beneficial effects: Since the present invention will Merger by radially tightening nut and washer fastening nut relative rotation in the circumferential direction limits the degree of freedom, so that, to achieve the purpose of locking, while the present invention has a simple structure, installation, the advantages of easy removal .

Description of drawings

Below in conjunction with accompanying drawing structure of the present invention is described further;

Fig. 1 is a structure principle chart of the present invention;

Fig. 4 is the unfolded drawing of radial packing ring.

Shown in the figure: 1, bolts; 2, Merger nut; 3, radial gasket; 4, fastening nut; 5, radial grooves; 6, vertical grooves.

Embodiment

Locking means having a Merger nut 2, the Merger nut 2 in the bottom there is a manufactured with the radial washer 2 similar shapes radial groove 5, the fastening nut 4 of the outer surface of a manufacture in the circumferential direction of the both portion with its axis parallel to the vertical grooves 6, with a fastening nut 4 is connected with the bolt, and tighten the bolt a fastening nut 4 is formed between the relationship will then set in a radial fastening bolt washer 3 4 projecting bolt 1 above, Merger nut 2 is installed in a radial gasket three upper protruding bolt 1 above, Merger nut 2 bottom radial grooves 5 down, when Merger nut 2 close radial gasket 3:00, the radial gasket 3 engaging the nut 2 in the bottom of the Merger radially within the recess 5 and continues to tighten the nut Merger 2, and to the gasket 3 radial branches radially outer side of the fastening nut 4 a vertical concave groove 6 of the positive and the radially the gasket 3 branches bent radially lying outer surface of the fastening nut 4 within a vertical recess 6.

Claims
