Description
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to a kind of lubrication screw.
Background technique
Screw is a kind of fastening piece conventional in daily life and industry, and screw after long-term use, owing to there is gap in its helical thread portion, if easily there is the phenomenon of getting rusty under humidity is long-term comparatively greatly, thus cause being difficult to screw be back-outed or is screwed into, if and specially go lubrication, lubrication effect is very poor again, cannot obtain the lubrication effect of expection.And fastened thing may occur expanding in summer, after particularly wood materials makes moist, the face of engagement easily expands, and such flank of thread is just very easy to be squeezed.Especially easily wear and tear at the flank of thread of screw like this, and the more important thing is, screw will be caused so stuck in fastened thing, be difficult to take out.
At present, on market (application number be 201220270765.3 Chinese patent disclose a kind of with lubrication pouring orifice bolt), although serve lubrication and antirust effect to a certain extent, but inner fluid can only be oozed out by oilhole, farthest can not cover whole thread surface and form oil film, farthest can not cover whole thread surface and form oil film, one denier air and moisture enter thread surface, or are very easy to the flank of thread surface of the above-mentioned model utility of corrosion thus cause internal rust.
Model utility content
For prior art exist can not complete attacking hole after form the deficiency of oil film in thread surface, form the screw of oil film after the purpose of this utility model is to provide a kind of can completing attacking hole in thread surface.
For achieving the above object, the utility model provides following technological scheme: a kind of lubrication screw, comprise main screw head and driving screw, described driving screw comprises partes glabra and the first screw section: described screw inside is provided with oil pocket, described oil pocket includes oil input channel and oil road, described oil input channel is communicated with the oil inlet hole being positioned at spiral shell head, described oil road is provided with the oil outlet being positioned at described partes glabra, described oil input channel has been threaded force feed pin, described force feed pin one end is provided with the force feed spiral shell head for coordinating screw-driver, the other end is provided with force feed rubber sleeve, the inwall interference fit of described force feed rubber sleeve and oil input channel.
Screw of the present utility model first can be screwed in screw by user, then lubricant oil is added oil pocket by oil inlet hole, then when fluid liquid level slowly rises, again force feed pin is inserted into oil duct, because oil pocket is set to " U " type, be convenient to the storage of fluid, due to oil pressure less (because the gap between screw thread and fastened thing is more) at the beginning, so insertion is comparatively easy, fluid will be squeezed out the outside of oil outlet via oil road, then along with force feed pin constantly downwards, oil pressure increases gradually, be difficult to continuation and will enter lubrication by hydraulic pressure, at this moment the force feed by being arranged at force feed pin is threaded into the internal thread of oil input channel, fluid is continued to extrude from oil outlet, make fluid can cover slow whole surface of contact as much as possible, play the effect of lubrication, and form one oil film, buffer action is played to outside air and moisture, prevent surface of contact from corroding, when summer, fastened thing expanded, force feed pin can also be unscrewed, inner relative pressure is reduced, make the utility model be not easy stuck causing can not take out.
The utility model can be set to further: described first screw section is provided with some damping holes, and described damping hole is communicated with the bottom of oil pocket by damp channel.By the setting of damping hole, in the process of force feed pin extruding, fluid slowly can also be oozed out from the first screw section outer surface by damping hole, one to ensure in force feed process can not oil pressure excessive, two, the first screw section and partes glabra are lubricated simultaneously, efficiency is higher, and effect more.
The utility model can be set to further: described oil outlet position is also provided with oil absorbent material.Arranging of oil absorbent material can ensure, fuel-displaced effect more, can not make fluid waste.
The utility model can be set to further: described partes glabra is also arranged with packer ring.When in screw driving screw being screwed in fastened thing, sealing rubber cover can play the locked effect of a sealing, ensure that fluid oozes out from screw when force feed.
The utility model can be set to further: described spiral shell head is provided with interior hexagonal screw channel, described oil inlet hole is communicated with the bottom being arranged at interior hexagonal screw channel, described force feed spiral shell head is provided with the first sphenoid surface, and described oil inlet hole is provided with the second sphenoid surface coordinated with the first sphenoid surface.By being equipped with of the first sphenoid surface and the second sphenoid surface, just can when screwing in force feed pin, play a spacing effect, and the second sphenoid surface also plays the function that facilitates oiling.
The utility model can be set to further: described oil outlet is evenly provided with four along partes glabra circumference, and the quantity of described oil road, damping hole and damp channel also correspondence is set to four.By arranging four groups of said structures, screw circumference of the present utility model can be lubricated, and effect more.
Compared to prior art, the utility model creates following beneficial effect: the effect that improve oiling and lubricating and antirust, and when summer, fastened thing expanded, force feed pin can also be unscrewed, inner relative pressure is reduced, and making the utility model be not easy stuck causing can not take out.
