Description

Integrated grooved oil pin Technical Field The utility model relates to the technical field of pin shafts, in particular to an integrated grooved oil pin. Background An oil pin is a mechanical connection that reduces friction and wear through a lubrication design (e.g., oil grooves, oil holes, or self-lubricating materials) and has the core function of improving the reliability, life, and smoothness of movement of the mechanical system. The device has the following defects found in practical use: If a high-efficient lubrication round pin axle (CN 213117034U) of current document, the reference is through having excavated the ripple groove in the bottom of round pin axle main part, at this moment with the connector installation back, the contact surface between ripple groove and the nut equipment diminishes, and lubricating oil can get into the inside in ripple groove, installs more easily, uses through the cooperation between connector, screw thread groove and the ripple groove to reach the effect of being convenient for install. As shown in the above document, the current lubrication pin with an oil groove generally has an oil guiding path inside the pin, and an oil outlet is formed on the surface of the pin, after the lubrication oil is injected, the lubrication oil is discharged through the oil outlet through the oil guiding path, and because the pin is generally fixed at the hinge position, the position of the oil outlet is also fixed correspondingly, so that the lubrication oil is difficult to fully contact with the hinge surface of the part. Accordingly, the present application provides an integrated slotted oil pin to meet the needs. Disclosure of utility model The utility model aims to solve the problems in the prior art and provides an integrated grooved oil pin. The utility model aims to solve the technical problem of providing an integrated grooved oil pin to solve the problem that lubricating oil of the existing pin shaft is difficult to comprehensively contact with a hinge surface of a part. In order to solve the technical problems, the utility model provides the following technical scheme: The utility model provides an integral type trough of belt oil round pin, includes movable sleeve and two side shield, and through-connection has leads oil pipe between the two side shield, it is provided with multiunit oil outlet to lead oil pipe's surface, movable sleeve rotates the middle part of installing at two side shield, and movable sleeve is inside to link up and has seted up the oil storage tank, and wherein leads oil pipe and is arranged in the oil storage tank to a channel oil outlet groove has been seted up at movable sleeve's surface.
