For important.The common uncoated antirust coat in bolt surface, bolt is easier to get rusty under rugged environment, corrosion-resistant, pole
Easily it is scratched, thus leading to the damage of screw thread.The bolt environmental contamination that some are coated with antirust coat is big, empty due to there are some
Between restriction it is desirable to it has Multifunctional bolt head to adapt to different types of fastening tool.With the continuous development of bolt, not only
Only to its fastening ability, the requirement to its sealing also steps up.
Utility model content
The purpose of utility model is for the problems referred to above, there is provided one kind is coated with the precious coating of heat rust, and environmental protection is corrosion-resistant,
Scratch-resistant, fit sealing good and have a Multifunctional bolt head scribble the precious bolt of heat rust.
For reaching above-mentioned purpose, utility model employs following technical proposal：Scribble the precious bolt of heat rust, including shank of bolt
With bolt head it is characterised in that described shank of bolt and bolt head connect into an entirety, its junction is provided with annulus close
Packing, sealing gasket lower port is angle shape, and described shank of bolt surface is provided with screw thread, and described bolt head profile is six sides
Shape, bolt head upper surface is additionally provided with a hexagonal shrinkage pool, bolt head upper surface is provided with three rhones simultaneously,
The surface of shank of bolt and bolt head is also coated with the precious coating of heat rust that a layer thickness is 10 μm.
Scribble in the precious bolt of heat rust in above-mentioned, on described shank of bolt, the ridge of screw thread is 35 °.
Scribble in the precious bolt of heat rust above-mentioned, described bolt head thickness 1.5CM, bolt head is through quencher simultaneously
Skill is processed.
Scribble in the precious bolt of heat rust in above-mentioned, the described precious coating of heat rust is one layer of no chrome coating, is applied by dipping lacquer
It is overlying on bolt surface.
Because shank of bolt and bolt head connect into an entirety, its junction is provided with annulus sealing gasket, under sealing gasket
Port is angle, and with the fastening effect of bolt, lower port is that the sealing gasket of angle is closely embedded in bolt hole, serves relatively
Good sealing function.Shank of bolt surface is provided with screw thread, and the ridge of screw thread is 35 °, by the setting of smaller angle ridge,
Preferably improve with by the degree of being completely embedded of fastening object, largely improve fit sealing.Bolt head thickness
1.5CM, bolt head profile is hexagon, and bolt head upper surface is additionally provided with a hexagonal shrinkage pool, and bolt head profile is six
Side shape, can be fastened by the fastening work of outer-hexagonal, upper surface is additionally provided with a hexagonal shrinkage pool, also can pass through interior
The fastening work of hexagonal is fastened, multi-functional bolt head design, can allow this bolt under various circumstances using corresponding
Instrument is operated.Bolt head upper surface is provided with the design of three rhones, when there being the moisture of residual in the shrinkage pool of bolt,
Can be discharged by rhone, greatly avoid by the phenomenon of getting rusty being led to of soaking for a long time, improve its corrosion resistance.?
The surface of shank of bolt and bolt head is also coated with the precious coating of heat rust of the Chrome-free that a layer thickness is 10 μm, and this coating first does not contain
Chromium, makes product become environmental protection, by the precious coating of heat rust, also improves its scratch resistance increasing its corrosion resistance simultaneously, it is to avoid
Because scraping produces, to screw thread, the phenomenon destroyed.
Compared with prior art, the advantage of utility model is：1st, lower port is the sealing gasket of angle and 35 ° of ridges
The design of screw thread, improves its fit sealing.2nd, the design of bolt hole hexagonal external feature and interior hexagon shrinkage pool, allows this bolt
Operated using corresponding instrument under various circumstances, become multi-functional.3rd, the application of rhone, improves it corrosion-resistant
Property.4th, the surface-coated of the precious coating of heat rust of 10 μm of Chrome-free is so as to become environmental protection, corrosion-resistant, scratch-resistant.
