Description
[technical field]
The utility model relates to mechanical frock field, especially a kind of antirust tapping screw.
[background technique]
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages
The tool of implements parts.Screw is the general saying of fastener, daily pet phrase.Screw is work indispensable in daily life
Industry necessity: the minimum screw that such as camera, glasses, clock and watch, electronics use；TV, electric product, musical instrument, furniture etc.
General screw；Large-scale screw, nut are then used as engineering, building, bridge；Traffic tool, aircraft, electric car, automobile etc. are then
It is used in combination for big Screw.Screw industrially bears vital task, as long as there is industry on the earth, the function of screw is eternal
It is important.Screw is the joint invention in people's production and living over the past thousands of years, and from the point of view of application field, it is the first big of the mankind
Invention.
Tapping screw in the prior art is typically necessary the corrosion in face of atmosphere and steam, and people are normal in process of production
One layer of antirust coat can be often plated to screw, but the effect is not very satisfactory for the antirust coat, once screw corrodes, fastening effect
The problems such as fruit decline, knockout screw is difficult, will come one after another, therefore, it is necessary to propose a kind of tapping screw of antirust.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of antirust tapping screw, Neng Goujian
While caring for tapping screw feature, also there is preferable rustless property.
To achieve the above object, the utility model proposes a kind of antirust tapping screw, including screw body, the screws
Main body is made of screw head and screw rod, and the screw head is equipped with screw and screws groove, and the screw rod lower end is equipped with screw tip, the spiral shell
Nail tip outer wall is equipped with tapping screw thread, and the screw head the center point is equipped with oil filler point, is equipped with internal screw thread, the spiral shell in the oil filler point
Bar center is equipped with oil storage tank, and the oil filler point and oil storage tank are interconnected, and the oil storage tank is equipped with several Oil Guide channels, described
Oil Guide channel radially communicates outside screw rod and screw rod outward, and the oil filler point is corresponding equipped with a size shape
Sealing bolt, the sealing bolt outside are equipped with external screw thread corresponding with oil filler point internal screw thread, and the sealing bolt is equipped with
Groove.
Preferably, it is regular hexagon that the screw, which screws groove,.
Preferably, the oil storage tank is cylinder, the oil storage tank is perpendicular to the ground.
Preferably, the quantity in the Oil Guide channel is 4, the Oil Guide channel is parallel to the ground.
Preferably, the groove is rectangle.
The utility model has the beneficial effects that the utility model inside screw body by being arranged oil filler point, oil storage tank, leading
The components such as oily channel allow the antirust oil being located in oil storage tank to flow to the screw surface of screw cylinder by Oil Guide channel,
And avoid antirust oil from directly contacting with ambient atmosphere sealing part of oil injection hole using sealing bolt, oxidation is generated, is set on sealing bolt
The internal screw thread of some external screw threads and oil filler point corresponds to each other, and improves sealing effect, the groove that sealing bolt is equipped with is conducive to
The installation and removal of sealing bolt, the tapping screw thread that screw tip is equipped with, so that screw body has the characteristic of self tapping, and it is existing
Technology is compared, and while taking into account tapping screw feature, also has preferable rustless property.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
