Abstract
The utility model discloses a kind of nylon locking nut, comprise hexagon nut body and loop configuration, described loop configuration is arranged at the upper end of hexagon nut body, hexagon nut body and loop configuration are formed in one structure, the inside of described hexagon nut body offers tapped hole, described tapped hole runs through whole hexagon nut body and loop configuration, and the inside of described loop configuration is provided with annular groove, is embedded with nylon washer in described annular groove.The utility model structure is simple, reasonable in design, during by nut is screwed into bolt, after coupling mechanism force strengthens, nylon is embedded in the parts of bolt, and the nylon washer after locking fills up the gap of bolts at two ends, thus play the effect of locking, nut after locking cannot in back-out, and anti-vibration, has stronger anti-loose ability strong simultaneously.
Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly a kind of technical field of nut.
[background technique]
In Fastener products, hexagonal nylon nut because of its there is self-locking function, structure is applied simply and on a large scale.The basic structure of hexagonal nylon nut is: comprise outer-hexagonal body and nylon washer, tapped hole is established in outer-hexagonal body, the upper-end surface of outer-hexagonal body is provided with thin walled cylinder body structure, after described nylon washer loads the endoporus of thin walled cylinder body, nylon washer is pressed on the upper-end surface of outer-hexagonal body by the upper end-hole of thin walled cylinder body to in-flanges, and the diameter of bore of nylon washer is less than the internal diameter of tapped hole.The hexagonal nylon nut of said structure in use most distinct issues is: nut install pull time, bolt can encounter nylon washer, nylon washer is inadequate due to the impacting force of the upper-end surface of hexagon outside, spins so easily produce, so just there is the problem of assembling difficulty.Connection between common nut and bolt, when having certain impact, easily produce and loosen and get loose, self-lock ability is poor.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of nylon locking nut, and structure is simple, and anti-loose ability is strong, and anti-vibration, can play the effect of locking by the distortion of nylon washer.
For achieving the above object, the utility model proposes a kind of nylon locking nut, comprise hexagon nut body and loop configuration, described loop configuration is arranged at the upper end of hexagon nut body, hexagon nut body and loop configuration are formed in one structure, and the inside of described hexagon nut body offers tapped hole, and described tapped hole runs through whole hexagon nut body and loop configuration, the inside of described loop configuration is provided with annular groove, is embedded with nylon washer in described annular groove.
As preferably, the internal diameter of described tapped hole is greater than the internal diameter of described nylon washer.
As preferably, the outer rim of described loop configuration is provided with rounding, and the opening of described tapped hole is provided with chamfering.
As preferably, the internal surface of described annular groove is provided with groove, is locked by groove between described nylon washer and annular groove.
As preferably, the sectional shape of described groove can be triangle, zigzag fashion or circular arc.
The beneficial effects of the utility model: the utility model structure is simple, and reasonable in design, cost of production is low, during by nut is screwed into bolt, after coupling mechanism force strengthens, nylon is embedded in the parts of bolt, and the nylon washer after locking fills up the gap of bolts at two ends, thus play the effect of locking, nut after locking cannot screw out again, anti-vibration, has stronger anti-loose ability strong simultaneously, locked by groove between nylon washer and annular groove, further increase the self-lock ability of nut.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the main TV structure figure of a kind of nylon locking of the utility model nut;
Fig. 2 is the plan structure figure of a kind of nylon locking nut of the utility model.
In figure: 1-hexagon nut body, 2-loop configuration, 3-nylon washer, 4-tapped hole, 5-annular groove, 6-groove, 7-rounding, 8-chamfering.
[embodiment]
Consult Fig. 1, Fig. 2, a kind of nylon locking nut of the utility model, comprise hexagon nut body 1 and loop configuration 2, described loop configuration 2 is arranged at the upper end of hexagon nut body 1, hexagon nut body 1 and loop configuration 2 are formed in one structure, the inside of described hexagon nut body 1 offers tapped hole 4, described tapped hole 4 runs through whole hexagon nut body 1 and loop configuration 2, the inside of described loop configuration 2 is provided with annular groove 5, nylon washer 3 is embedded with in described annular groove 5, the internal diameter of described tapped hole 4 is greater than the internal diameter of described nylon washer 3, the outer rim of described loop configuration 2 is provided with rounding 7, the opening of described tapped hole 4 is provided with chamfering 8, the internal surface of described annular groove 5 is provided with groove 6, locked by groove 6 between described nylon washer 3 and annular groove 5, the sectional shape of described groove 6 can be triangle, zigzag fashion or circular arc.
Utility model works process:
A kind of nylon locking nut of the utility model in the course of the work, when mounted, nut and the link such as threaded screw or bolt with the use of, nut is screwed in bolt, after coupling mechanism force strengthens, nylon is embedded in the parts of bolt, and the internal diameter due to tapped hole 4 is greater than the internal diameter of described nylon washer 3, and the nylon washer 3 after locking fills up the gap of bolts at two ends, thus play the effect of locking, nut after locking in back-out, cannot have stronger anti-loose ability strong, anti-vibration simultaneously.Further, the internal surface of annular groove 5 is provided with groove 6, locked by groove 6 between described nylon washer 3 and annular groove 5, the effect of groove 6 increases the connectivity between nylon washer 3 and loop configuration 2 inwall, the sectional shape of groove 6 can be triangle, zigzag fashion or circular arc, when nylon washer 3 is embedded in connected piece bolt, the two ends of nylon washer 3, all by pinning tightly, further increase the self-lock ability of nut.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
