Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a round pin axle with lubricating function.

In this embodiment, referring to fig. 1 to 4, this round pin axle with lubricating function includes round pin body 1 and round pin head 2, the afterbody of round pin body 1 is equipped with locking hole 3, round pin head 2 on be equipped with counter sink 4, the bottom of counter sink 4 is equipped with axial oil duct 5 that extends to locking hole the place ahead, round pin body is equidistant to be equipped with a plurality of radial oil ducts 6 that are linked together with axial oil duct 5, it has shield 7 to articulate through the pivot on the opening of counter sink 4, threaded connection has plunger 8 on the import of axial oil duct 5.

The utility model discloses a in the time of using, with the plunger from the import of axial oil duct screwing down, then toward pouring into lubricating oil in the radial oil duct, lubricating oil flows to round pin axle surface through axial oil duct and radial oil duct, to the round pin axle with lubricated by the contact surface between the connecting piece, can prevent effectively that the round pin axle from corroding, it is lubricated convenient, the radial oil duct of all cloths can improve lubricated validity in addition.

Specifically, the radial oil passage 6 is of a conical structure; still include connecting block 9 and pull

ring

10, 9 integrated into one piece of connecting block is in the bottom of heavy groove 4, be equipped with the connecting hole of through connection piece on the connecting block, be equipped with breach 11 on one side of pull ring 10, it has connecting axle 12 to extend on the pull ring both ends that are located breach 11, connecting axle 12 stretches into in the connecting hole and connecting block swivelling joint.
