Abstract
The utility model discloses hexagonal nylon nut, comprise outer-hexagonal body and nylon spacer, 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 spacer loads the endoporus of thin walled cylinder body, nylon spacer is pressed on the upper-end surface of outer-hexagonal body by the upper end-hole of thin walled cylinder body to in-flanges, the diameter of bore of nylon spacer is less than the internal diameter of tapped hole, it is characterized in that: the lower end surface of described nylon spacer is provided with protrusion skewback and is inserted in described tapped hole downwards, and the hole wall of described tapped hole is provided with the skewed slot corresponding with skewback.When the utility model can effectively prevent nut from pulling, nylon spacer spins, assembles the situations such as difficulty, and appearance quality is good, cost of production is low.
Description
Technical field
The utility model relates to a kind of Fastener products, is specifically related to a kind of improvement invention of hexagonal nylon 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 spacer, 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 spacer loads the endoporus of thin walled cylinder body, nylon spacer 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 spacer 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 spacer, nylon spacer 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.Maximum methods of current employing are that the several depression of punching press improves the impacting force to nylon spacer again at the in-flanges top of thin walled cylinder body upper end-hole, but still unavoidably there is the problem that impacting force is inadequate, especially when the endoporus of nylon spacer and the deviation at tapped hole center exceed standard; The depression of punching press can destroy the appearance quality of nut in addition, also can therefore destroy nut table finishing coat and make nut more perishable.Further, in prior art, the thin walled cylinder body of outer-hexagonal body upper-end surface is thin due to wall, and be all come by turnery processing at present, manufacturing efficiency is low, and processing cost is high.
Summary of the invention
In view of current known technology Problems existing, the technical problems to be solved in the utility model is that when being to provide one effectively to prevent nut from pulling, nylon spacer spins, assembles the situations such as difficulty, and the hexagonal nylon nut that appearance quality is good, cost of production is low.
The utility model is implemented by the following technical programs:
Hexagonal nylon nut, comprise outer-hexagonal body and nylon spacer, 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 spacer loads the endoporus of thin walled cylinder body, nylon spacer is pressed on the upper-end surface of outer-hexagonal body by the upper end-hole of thin walled cylinder body to in-flanges, the diameter of bore of nylon spacer is less than the internal diameter of tapped hole, it is characterized in that: the lower end surface of described nylon spacer is provided with protrusion skewback and is inserted in described tapped hole downwards, and the hole wall of described tapped hole is provided with the skewed slot corresponding with skewback.Outer-hexagonal body, thin walled cylinder body and skewed slot by metal wire rod in cold-heading time together with shaping.
Have employed the hexagonal nylon nut of technique scheme, compared with prior art have the following advantages: 1. the lower end surface of nylon spacer is provided with and protrudes in skewed slot that the skewback hole wall that is inserted into described tapped hole is provided with downwards, after the in-flanges of thin walled cylinder body upper end-hole compresses nylon spacer, just effectively prevent spinning of nylon spacer when nut is pulled by the circumferential position-limiting action of skewed slot to skewback, thus make assembling become convenient; 2., because the in-flanges top of thin walled cylinder body upper end-hole does not need punching press again to cave in the impacting force improved nylon spacer, so the appearance quality of hexagonal nylon nut is good, therefore nut table finishing coat also would not be damaged and become and more easily be corroded; 3. outer-hexagonal body, thin walled cylinder body and skewed slot are by shaping together with metal wire rod is when cold-heading, thus avoid turning and slotting machine processing, enhance productivity, cut down finished cost.
As preferably, described skewback is provided with three places in the lower end surface of nylon spacer, described skewed slot tapped hole hole wall also correspondence be provided with three places.

Embodiment
Details and the working principle of the utility model specific embodiment is described in detail below in conjunction with accompanying drawing:
As shown in the figure, hexagonal nylon nut of the present utility model, comprise outer-hexagonal body 1 and nylon spacer 6, tapped hole is established in outer-hexagonal body 1, the upper-end surface of outer-hexagonal body 1 is provided with thin walled cylinder body 2 structure, after described nylon spacer 6 loads the endoporus of thin walled cylinder body 2, nylon spacer 6 is pressed on the upper-end surface of outer-hexagonal body 1 by the upper end-hole of thin walled cylinder body 2 to in-flanges 3, the diameter of bore of nylon spacer 6 is slightly smaller than the internal diameter of tapped hole, the lower end surface of described nylon spacer 6 is provided with protrusion skewback 4 and is inserted in described tapped hole downwards, the hole wall of described tapped hole is provided with the skewed slot 5 corresponding with skewback 4, described skewback 4 is provided with three places in the lower end surface of nylon spacer 6, described skewed slot 5 tapped hole hole wall also correspondence be provided with three places, outer-hexagonal body 1, thin walled cylinder body 2 and skewed slot 5 by metal wire rod in cold-heading time together with shaping.
Hexagonal nylon nut of the present utility model in use, when pulling outer-hexagonal body by spanner, bolt upwards can encounter nylon spacer, nylon spacer is spacing owing to obtaining good circumference reliably, spin so there will not be, such bolt just easily can enter the endoporus of nylon spacer, is out of shape the frictional force strengthening relative movement between bolt thread, thus plays certain nut check effect by nylon spacer by own material.
