Background technology
Bolt has dismountable feature, facilitated between connected piece as a kind of fastener for object connection
Connection and replacing, so as to be widely used on various apparatuses.
Bolt after a long time use, especially for the long-term bolt into water, gets rusty easily.For the spiral shell to get rusty
It silk, must not firmly be twisted with spanner, to prevent twisting six face corner angle of sliding screw, twist into two parts screw or twist bad spanner.Therefore, how to improve
The antirust ability of bolt, it is to solve get rusty Bolt dismantling and the subject matter of installation.
The content of the invention
It is an object of the invention to provide a kind of anti-corrosion bolt, can either prevent that bolt rust is dead, have lubrication again,
Protect bolt normally to screw in and dismantle, improve bolt performance.
To use following technical scheme up to this purpose, the present invention：
A kind of anti-corrosion bolt, including integrally formed screw rod and bolt head, the bolt head is cylindrical into hexagonal structure, described
1 counterbore with screw coaxial is provided with the remote screw rod upper surface of bolt head, is set in the counterbore and is divided into counterbore
Upper chamber and the dividing plate of lower chambers, being coaxially set in the screw rod has the blind hole extended along spiro rod length direction, the cavity of resorption
Interior is provided with the several pipelines being passed through in blind hole, and being in charge of along pipe lengths interval is respectively arranged with the pipeline,
It is described be in charge of point to screw rod it is cylindrical.
In a preferred embodiments of the invention, the screw rod is cylindrical to be provided with the through hole corresponding with being in charge of, described to be in charge of
Communicated with through hole.
In a preferred embodiments of the invention, the cover plate being sealed against is provided with above the counterbore.
In a preferred embodiments of the invention, depression bar straight up, the middle part of the depression bar are provided with the dividing plate
The sleeve being located on cover plate is provided with, the stage clip being sleeved on the outside of depression bar is provided with the sleeve.
In a preferred embodiments of the invention, the circular port that is provided with the dividing plate below depression bar.
In a preferred embodiments of the invention, the depression bar bottom is provided with sealing plate, and the external diameter of the sealing plate is more than
Through 0.5mm in circular port.
In a preferred embodiments of the invention, the sealing plate is process for rubber slab.
Beneficial effects of the present invention：A kind of anti-corrosion bolt, after bolt long-time use, corrosion easily occurs, passes through
Counterbore pours into lubricating oil, and lubricating oil is flowed into screw flight with pipeline, can either prevent that bolt rust is dead, again there is lubrication to make
With protection bolt normally screws in and dismounting, improves bolt performance.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Technical scheme is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of anti-corrosion bolt, including integrally formed screw rod 1 and bolt head 2, the bolt head 2 are cylindrical into hexagon knot
Structure, is provided with 1 counterbore 21 coaxial with screw rod 1 on the upper surface of remote screw rod 1 of the bolt head 2, in the counterbore 21
The dividing plate 3 that counterbore 21 is divided into upper chamber 22 and lower chambers 23 is set, and being coaxially set in the screw rod 1 has along the length of screw rod 1
The blind hole 11 of direction extension, is provided with the several pipelines 4 being passed through in blind 11 hole in the lower chambers 23, on the pipeline 4 respectively
It is provided with along the length direction interval of pipeline 4 and is in charge of 5, described to be in charge of 5 sensing screw rods 1 cylindrical.
In above-mentioned, the memory storage lubricating oil of upper chamber 22 is used.
Further, the screw rod 1 is cylindrical is provided with the through hole 12 corresponding with being in charge of 5, described to be in charge of 5 and the phase of through hole 12
It is logical.Flow into and be in charge of the lubricating oil in 5 into the outside of outflow screw rod 1 after through hole 12, make to produce profit between screw rod 1 and connector
It is sliding, prevent that bolt rust is dead.
Further, the top of counterbore 21 is provided with the cover plate 6 being sealed against, and prevents the lubricating oil in upper chamber 22 from letting out
Dew.
Further, depression bar 7 straight up is provided with the dividing plate 3, the middle part of the depression bar 7 is provided with positioned at cover plate
