Abstract
The invention discloses a connecting pin with a good lubricating effect. The connecting pin comprises a head part and a rod part. The vertically-downward projection of the head part can completely cover the rod part. Two axial thread drainage grooves directly communicated with the bottom end are symmetrically formed in the rod part, and extend upwards to the contact position between the rod part and the head part. The head part is provided with an oil injection channel, and is respectively communicated with the two axial thread drainage grooves in the rod part. Due to the fact that the two axial thread drainage grooves directly communicated with the bottom end are symmetrically formed in the rod part of the connecting pin, lubrication oil in the oil injection channel formed in the head part can flow to the bottom end of the rod part of the connecting pin well when the connecting pin is used, and the outer circular face of the connecting pin can be lubricated well. An opening part of the oil injection channel is in a funnel shape, so that the lubrication oil flows into the oil injection channel conveniently.
Description
Technical field
The present invention relates to a kind of link, specifically a kind of connecting pin of high lubricating effect.
Background technique
Connect two or more while thering are in relative rotation component, usually need to use connecting pin to connect, in the process of rotating relative to connecting pin at component, can produce larger frictional force, therefore need to use oil lubrication, add lubricant oil for convenient on the periphery of connecting pin, usually be provided with axial oiling passage on an end face of connecting pin, and be provided with radially oiling passage on the periphery of connecting pin, axially the oiling passage communicates with oiling passage radially, lubricant oil by axial oiling passage and radially the oiling passage enter on the connecting pin periphery, and then be diffused into the periphery of whole connecting pin, because the working environment of connecting pin is poor, the dust that the external world enters easily hinders the diffusion of lubricant oil, therefore, on connecting pin, away from the periphery of oiling channel exit radially, can not lubricate preferably, thereby make the too early wearing and tearing of component and connecting pin.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: the connecting pin that has proposed a kind of high lubricating effect.
Technical solution of the present invention is achieved in that a kind of connecting pin of high lubricating effect, comprises head and rod body, and the projection vertically downward of described head can cover rod body fully; Be provided with symmetrically the axial screw thread drainage trough of two straight-through bottoms on described rod body, and described axial screw thread drainage trough upwards extends to the contact position between rod body and head always; Described head is provided with the oiling passage, and respectively be arranged on rod body on two axial screw thread drainage troughs be connected.
Further, the opening portion of described oiling passage is arranged to funnel-like.
Further, the cross section of described head is arranged to hexagon.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The connecting pin of the described high lubricating effect of the present invention program is because the rod body at connecting pin is provided with the axial screw thread drainage trough of two straight-through bottoms symmetrically, the lubricant oil that makes like this its oiling passage of offering on by head in the process of using inject can flow to the bottom of connecting pin rod body preferably, and then makes the periphery of connecting pin obtain lubrication preferably; The opening portion of oiling passage is arranged to funnel-like, has facilitated like this inflow of lubricant oil simultaneously.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation of the connecting pin that accompanying drawing 1 is high lubricating effect of the present invention;
The sectional view of the connecting pin that accompanying drawing 2 is high lubricating effect of the present invention;
Wherein: 1, head; 2, rod body; 3, axial screw thread drainage trough; 4, oiling passage.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
The connecting pin that accompanying drawing 1-2 is a kind of high lubricating effect of the present invention, comprise head 1 and rod body 2, and the projection vertically downward of described head 1 can cover rod body 2 fully; Be provided with symmetrically the axial screw thread drainage trough 3 of two straight-through bottoms on described rod body 2, and described axial screw thread drainage trough 3 upwards extends to the contact position between rod body 2 and head 1 always; Described head 1 is provided with oiling passage 4, and respectively be arranged on rod body 2 on two axial screw thread drainage troughs 3 be connected.
The opening portion of wherein said oiling passage 4 is arranged to funnel-like; The cross section of described head 1 is arranged to hexagon.
The connecting pin of high lubricating effect of the present invention is because the rod body 2 at connecting pin is provided with the axial screw thread drainage trough 3 of two straight-through bottoms symmetrically, the lubricant oil that makes like this its oiling passage 4 of offering on by head 1 in the process of using inject can flow to the bottom of connecting pin rod body 2 preferably, and then makes the periphery of connecting pin obtain lubrication preferably; The opening portion of oiling passage 4 is arranged to funnel-like, has facilitated like this inflow of lubricant oil simultaneously.
The connecting pin of high lubricating effect of the present invention its arrange oiling passage 4 and axial screw thread drainage trough 3 be communicated with branch road the time, can be arranged to the branch road with certain radian to oiling passage 4 for two branches that connect axial screw thread drainage trough 3, make like this lubricant oil injected from oiling passage 4 can flow into more easily axial screw thread drainage trough 3, lubricant oil is along with the drainage of axial screw thread drainage trough 3 is taken lubricant oil at each position of connecting pin periphery afterwards, and it is lubricated to effect.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
