Abstract
The utility model discloses a kind of flanged surface nylon nut, comprise nut body, annular protrusion and pad, described nut body upper end arranges annular protrusion, described pad is arranged at the lower end of nut body, described nut body, annular protrusion and pad are formed in one structure, groove is provided with inside described annular protrusion, nylon washer is embedded with in described groove, described nut body and pad center offer the first center hole, the opening of described first center hole is provided with chamfering, the inner side of described nylon washer arranges the second through hole, the axis of described first center hole and the second through hole overlaps.The utility model structure is simple, easy for installation, by the setting of nylon spacer, nylon is embedded on bolt, thus plays the effect of locking, and this locking is not reciprocally, just again can not screw out, therefore have stronger lock ability after locking.
Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly a kind of technical field of locking 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.When general nut is connected with bolt, there is gap between pad and nut, easily produce and loosen, be not suitable for the occasion vibrated, the 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 flanged surface nylon nut, and structure is simple, easy for installation, anti-loose, and locking back nut cannot screw out, and self-lock ability is strong.
For achieving the above object, the utility model proposes a kind of flanged surface nylon nut, comprise nut body, annular protrusion and pad, described nut body upper end arranges annular protrusion, described pad is arranged at the lower end of nut body, described nut body, annular protrusion and pad are formed in one structure, groove is provided with inside described annular protrusion, nylon washer is embedded with in described groove, described nut body and pad center offer the first center hole, the opening of described first center hole is provided with chamfering, the inner side of described nylon washer arranges the second through hole, the axis of described first center hole and the second through hole overlaps.
As preferably, attacked screw thread inside described first center hole, the size of described second through hole internal diameter is less than the size of the first center hole internal diameter.
As preferably, the lower surface of described pad is provided with anti-skidding groove, described anti-skidding groove distributes around the first center hole circular array.
As preferably, the structure of described anti-skidding groove is " S " type, and the quantity of anti-skidding groove is 20 ~ 30 roads.
As preferably, the outer rim of described pad is provided with rounding.
The beneficial effects of the utility model: the utility model structure is simple, easy for installation, by the setting of nylon spacer, nylon is embedded on bolt, thus play the effect of locking, this locking is not reciprocally, just can not again screw out after locking, therefore there is stronger lock ability, additionally use the structure of pad and nut body integral type simultaneously, avoid the gap between original nut and pad, the lower surface of pad is provided with anti-skidding groove, add the frictional force between basal plane, strengthen anti-loose ability, possessed certain anti-vibration ability simultaneously.
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 flanged surface of the utility model nylon nut;
Fig. 2 is the plan structure figure of a kind of flanged surface nylon nut of the utility model;
Fig. 3 is the face upwarding assumption diagram of a kind of flanged surface nylon nut of the utility model.
In figure: 1-nut body, 2-annular protrusion, 3-pad, 4-nylon washer, 5-first center hole, 6-second through hole, 7-rounding, the anti-skidding groove of 31-.
[embodiment]
Consult Fig. 1, Fig. 2, Fig. 3, a kind of flanged surface nylon nut of the utility model, comprise nut body 1, annular protrusion 2 and pad 3, described nut body 1 upper end arranges annular protrusion 2, described pad 3 is arranged at the lower end of nut body 1, described nut body 1, annular protrusion 2 and pad 3 are formed in one structure, groove is provided with inside described annular protrusion 2, nylon washer 4 is embedded with in described groove, described nut body 1 and pad 3 center offer the first center hole 5, the opening of described first center hole 5 is provided with chamfering, the inner side of described nylon washer 4 arranges the second through hole 6, the axis of described first center hole 5 and the second through hole 6 overlaps, screw thread has been attacked inside described first center hole 5, the size of described second through hole 6 internal diameter is less than the size of the first center hole 5 internal diameter, the lower surface of described pad 3 is provided with anti-skidding groove 31, described anti-skidding groove 31 distributes around the first center hole 5 circular array, the structure of described anti-skidding groove 31 is " S " type, the quantity of anti-skidding groove 31 is 20 ~ 30 roads, the outer rim of described pad 3 is provided with rounding 7.
Utility model works process:
A kind of flanged surface nylon nut of the utility model in the course of the work, nut body 1 and pad 3 center offer the first center hole 5, the inner side of nylon washer 4 arranges the second through hole 6, screw thread has been attacked inside first center hole 5, the size of the second through hole 6 internal diameter is less than the size of the first center hole 5 internal diameter, in installation process, when nut is screwed into bolt, be screwed in nylon washer 4, after coupling mechanism force strengthens, nylon is embedded on bolt, nylon washer 4 after locking fills up the gap of bolts at two ends, thus play the effect of locking, this locking is not reciprocally, just can not again screw out after locking, therefore there is stronger lock ability.Further, described flanged surface nylon nut additionally uses the structure of packing ring integral type, nut body 1, annular protrusion 2 and pad 3 are formed in one structure, avoid the gap between original nut and pad, the lower surface of pad 3 is provided with anti-skidding groove 31, the groove of " S " type has stronger resistance, adds the frictional force between basal plane, strengthen anti-loose ability, possess certain anti-vibration ability simultaneously.
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.
