Abstract

The invention discloses a dowel. The dowel comprises a shaft head, a shaft body and a baffle. The shaft head and the baffle are arranged on the two sides of the shaft body respectively. A groove is formed on one side, close to the shaft head, of the shaft body. Oil inlet holes and oil outlet holes are formed in the shaft head and the shaft body respectively, the oil inlet holes and the oil outlet holes are mutually communicated, the oil inlet holes and the oil outlet holes are perpendicularly arranged, and the diameters of the oil outlet holes are smaller than the diameters of the oil inlet holes. When the dowel is used, lubricating oil can be filled from the oil inlet holes, so that the lubrication degree of a contact part between the dowel and an object fixed by the dowel is increased, and then the dowel can be easily detached from the object fixed by the dowel. The diameters of the oil outlet holes are smaller than the diameters of the oil inlet holes, the lubricating oil filled from the oil inlet holes can slowly flow out from the oil outlet holes, and the utilization rate of the lubricating oil is improved.

Description

Technical field [0001] The invention relates to a connecting component, in particular to an easily detachable shaft pin. Background technique [0002] Axle pin is a connecting part used to connect and fix two objects with through holes. After a long time of use, the contact part between the pin and the connected and fixed object is easy to be stuck due to rust and is not easy to Disassemble. Summary of the invention [0003] In view of the above-mentioned technical problems, the purpose of the present invention is to provide an easily detachable shaft pin. [0004] The technical solution of the present invention is realized as follows: a shaft pin includes a shaft head, a shaft body and a baffle, the shaft head and the baffle are separated on both sides of the shaft body; the shaft body is located near the shaft head One side is provided with a groove; the shaft head and the shaft body are respectively provided with an oil inlet and an oil outlet communicating with each other, and...
