Abstract
The invention discloses a nut, and particularly relates to a nut in an anti-rust structure, comprising a common nut. The common nut is provided with an oil storage groove and an oil hole, wherein the oil storage groove is arranged in the axial middle of an internal thread of the common nut, and the oil hole is arranged on the hexagonal surface and mutually communicated with the oil storage groove. The nut in the structure has simple structure, safety, reliability, is easy for implementation, can prolong the service life of a similar fastener by approximate three times and improve the maintenance reliability twice.
Description
Technical field
The present invention relates to a kind of nut with anti-rust structure.
Background technique
Nut is an internal thread fastening piece of finishing fastening function with the threaded male fastener adapted jointly.Since the bolt invention, nut also just has been born, and it and bolt are rated as a pair of heterosexual twins.But plain nut only plays the role of fastening, and does not have other function.We often find, in the open or very easily bolt, the nut assembly that uses in the oxidative environment often can't or be difficult for unclamping because of corrosion, thereby causes engineering goods to lose efficacy or maintenance difficult.Develop rapidly along with modern industry, nut has obtained extensive use in different field, especially in some particular surroundingss and occasion, nut has been proposed various harsh requirements, therefore need satisfy these harsh requirements by plain nut being carried out some structural improvement.
Summary of the invention
The object of the present invention is to provide a kind of nut that uses in the working environment in the open a kind of or very easily oxidation with anti-corrosion structure.
The nut that this has the anti-corrosion structure comprises plain nut, is provided with oil storage groove and oil hole on plain nut, and the oil storage groove is positioned at the axial middle part of plain nut internal thread, and oil hole is positioned on the hex surface, and oil storage groove and oil hole are interconnected.
The oil storage groove dimensions is: dark 1～10mm, and wide: 2～14mm.
The quantity of oil hole is 3～6.
Adopt the nut of this kind structure, simple in structure, safe and reliable, easy to implemently can make the similar fastening piece life-span improve nearly three times, maintenance reliability is doubled.
Description of drawings
Fig. 1 is the side structure schematic representation of nut of the present invention;
Fig. 2 is the Facad structure schematic representation of nut of the present invention;
Embodiment
The structural representation of nut as shown in Figure 1, it comprises: oil storage groove 1, oil hole 2, plain nut 3.Process one in plain nut 3 inside and store rust preventive oil groove 1, get out the oil hole 2 that communicates with oil storage groove 1 at hex surface simultaneously.Nut of the present invention an amount of rust preventive oil of injection when assembling is assemblied in then and has effectively prevented the corrosion problem on the bolt, the antirust oil plant in threaded connection place after the assembling is very even, if check and find directly to be coated with rust preventive oil when rust preventive oil is very few, and then replenish oil plant from oil hole 2 to the threaded connection place.When the later stage is checked, can not back out nut completely, and directly the oil hole 2 on six aspects carries out oil plant and replenishes as finding oil plant.And, in case when corrosion occurring and can't back out nut, can also inject kerosene etc.,, can take off nut with comparalive ease through after the suitable stand-by period by oil hole 2.
The present invention takes cheaply machining process that plain nut 3 is processed; Dig out oil storage groove 1 to the middle part with boring cutter in female threaded shaft then, groove dimensions can be: dark: 1～10mm, wide: 2～14mm, concrete size waits to determine according to plain nut 3 sizes and requirement of strength; The last oil hole 2 that communicates with oil storage groove 1 that on hex surface, bores, the quantity of oil hole can be 3～6, and diameter is φ 1～6mm, and concrete quantity can increase and decrease according to the product actual conditions.
The present invention is simple in structure, and is easy to implement, and effect is obvious, can be popularized and applied to various mechanical industries.
