Through adopting above-mentioned technical scheme, soft material and orientation make keep off the piece when pushing away oil and stretch out and more easily push away from and push away oil to avoid the butter to be strikeed off completely by the doctor-bar, and when income round pin is internal, because push away oil drive and make the doctor-bar to pushing away the laminating of oil, thereby let the doctor-bar will push away the butter on the oil piece and scrape away, make the butter pushed away oil and send to round pin body surface from the oil storage intracavity.
Preferably, a one-way valve is arranged at the communication position of the oil storage cavity and the outside.
Through adopting above-mentioned technical scheme, the check valve makes can inhale the oil storage intracavity with the air after the butter is sent out for the butter in the oil storage intracavity is pushed the oil-out by the air, thereby lets the butter in the oil storage intracavity can be constantly pushed the oil-out, and is sent to the pin body surface along the oil-out, reaches better lubricated effect.
Preferably, the surface of the pin body is provided with a lubricating groove connected with the oil outlet.
By adopting the technical scheme, the lubricating groove enables the grease to spread to the pin bodies along the lubricating groove after being pushed out of the pin bodies.
Preferably, the lubrication groove is helical around the pin body.
Through adopting above-mentioned technical scheme, the heliciform makes the circumference of the lubricated pin body that butter can be abundant when removing.
Preferably, the pin body is provided with a positioning groove for keeping the oil outlet in a vertical upward direction.
Through adopting above-mentioned technical scheme, because the relation of gravity for the main upper portion in vertical direction of round pin body atress position, through sending the butter to atress department, reduce the surface friction of atress department, thereby reduce holistic frictional force.
Compared with the prior art, the utility model has the beneficial effects that: the shaking that produces when using through equipment itself promotes and pushes away oily piece for push away oily piece and push away the butter and push out round pin body surface and reach lubricated effect, thereby avoid the butter to block up in the unable use of oil storage intracavity.

Detailed Description
In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the designated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a self-lubricating knuckle kingpin, including a pin body 1, the middle part of the pin body 1 is provided with an oil storage cavity 2 and an oil outlet 6 which are communicated with each other, the oil outlet 6 is provided with a scraping piece 5, the oil outlet 6 is slidably provided with an oil pushing piece 3, the oil pushing piece 3 is provided with an elastic piece 4 which enables the oil pushing piece 3 to protrude out of the surface of the pin body 1 between the pin bodies 1, the oil pushing piece 3 and the scraping piece 5 can be pressed against each other, the pin body 1 is detachably connected with a blocking piece 7 which is used for preventing the oil pushing piece 3 from separating from the surface of the pin body 1, the scraping piece 5 is arranged on the blocking piece 7, the blocking piece 7 is made of soft material, the periphery of the blocking piece 7 is obliquely arranged away from the oil storage cavity 2 in the direction with the fixed middle part of the blocking piece 7, a one-way valve is arranged at the communication part between the oil storage cavity 2 and the outside, and the pin body 1 is provided with a positioning groove 9 which enables the oil outlet 6 to keep the vertical upward direction.
Earlier scribble the butter on round pin body 1 surface during the use, inside inserting round pin body 1 again and rotating the festival, will stick out earlier in round pin body 1 surperficial oil pushing member 3 impresses the oil storage chamber 2 during the installation, push away oil member 3 and can hinder normal installation when avoiding installing, then push away round pin body 1 to suitable position to insert to constant head tank 9 through the bolt in, thereby it is fixed with round pin body 1, then extrude the oil storage chamber 2 at round pin body 1 middle part with the nozzle in with the butter, accomplish the installation. When the grease pushing device is used, the rotating joint per se can vibrate along with the vibration of the device per se, the vibrating rotating joint can impact the grease pushing part 3, so that the grease pushing part 3 is stressed to compress the elastic part 4 and then retracts into the grease storage cavity 2, when the grease pushing part 3 retracts into the grease storage cavity 2, the retracted grease pushing part 3 can drive the scraping blade 5 to lean against the grease pushing part 3 due to the fact that the scraping blade 5 faces towards the outer part of the grease storage cavity 2, grease on the grease pushing part 3 is scraped, after the grease pushing part 3 is pushed back into the grease storage cavity 2, the grease pushing part 3 losing external force is outwards popped up under the action of the restoring force of the elastic part 4, the grease pushing part 3 entering the grease storage cavity 2 is fully stained with grease due to the fact that the grease is filled in the grease storage cavity 2, when the grease pushing part 3 extends out, the scraping blade 5 faces outwards, when the grease pushing part 3 pushes the scraping blade 5 cannot be stuck to the surface of the grease pushing part 3, and therefore a part of the grease pushing part 3 can push out the grease along with the surface of the grease pushing part 1, reach the effect of automatic oiling to when the butter is taken away out, because inside butter reduces, make inside atmospheric pressure reduce, thereby inhale the oil storage chamber 2 through the air of check valve with the outside in, make the butter in the oil storage chamber 2 remove to pushing away oil spare 3 by air thrust, reach the effect that further utilizes the butter in the oil storage chamber 2.
The surface of the pin body 1 is provided with a spiral lubricating groove 8 connected with the oil outlet 6, and the spiral lubricating groove 8 is arranged, so that when the pin body 1 is used, the grease can be pushed to the peripheral surface of the pin body 1 along the lubricating groove 8, the surface of the pin body 1 is evenly coated with the grease, the friction force between the pin body 1 and the rotating joint is reduced, and the pin body 1 can be used for a longer time.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
