because the runner 53 is located at the lower side of the oil outlet hole 523, and a part of the oil outlet hole 523 corresponding to the runner 53 is located at the directly upper side of the runner 53; therefore, under the vibration action, a part of the lubricating oil flowing downwards flows into the sliding groove 53 and flows downwards along the sliding groove 53 in a concentrated way, so that the contact gap between the sliding block 54 and the sliding groove 53 is filled with the lubricating oil, the lubricating oil is fully lubricated, the friction resistance between the sliding block 54 and the sliding groove 53 is reduced, the sliding of the sliding block 54 and the sliding groove 53 is smoother, and the utilization rate of the lubricating oil is improved;
further, a clearance can be kept between other parts except the sliding block 54 and the surface of the limiting groove 52, which is optionally arranged on the end part of the limiting block 51, so that the contact effect is mainly concentrated in the sliding block 54 and the sliding groove 53; the oil outlet 523 can also keep the position opposite to the chute 53, so that the lubricating oil intensively flows through the chute 53 and acts on the relative sliding of the sliding block 54 and the chute 53, so that the lubricating oil is utilized to the greatest extent, the abrasion of the limiting block 51 is reduced, and the smooth limiting sliding of the limiting block 51 in the limiting groove 52 is ensured.
Fifth embodiment:
on the basis of the fourth embodiment, as shown in fig. 2-7 in the drawings of the specification, an oil storage groove 55 is transversely arranged on the inner wall of the limit groove 52 near the bottom of the sliding groove 53, and an oil absorption sponge 551 is arranged in the oil storage groove 55; an oil collecting cavity 552 is arranged in the side wall of the oil storage groove 55, a partition plate 553 is arranged between the oil collecting cavity 552 and the oil storage groove 55, communication holes 557 are uniformly formed in the partition plate 553, the oil collecting cavity 552 is communicated with the inside of the oil storage cavity 521 through a transmission channel 554, and the transmission channel 554 can be of a tubular structure; the outer surface of the part of the oil absorption sponge 551 corresponding to the sliding block 54 is provided with a pressing plate 555, the pressing plate 555 is of an arc structure, and the outer part is of an arc surface; the communication hole 557 provided on the partition plate 553 is a tapered hole, and a small end of the communication hole 557 is positioned at one side close to the inside of the oil collecting cavity 552;
the specific working flow is as follows: on the basis of the specific working flow in the fourth embodiment, during the sliding lubrication process of the limiting block 51, the lubricating oil flows downwards and is converged at the lower side position, so that the lubricating oil is difficult to reuse, and the continuous consumption of the lubricating oil in the oil storage cavity 521 can be caused; when the use frequency of the pipeline is high, vibration is aggravated, the limiting block 51 also frequently slides in the limiting groove 52, so that the lubricating oil in the oil storage cavity 521 is consumed more quickly, frequent replenishment is needed, and the maintenance cost is increased; under the condition of untimely replenishment, the lack of lubrication can increase the friction resistance between the sliding block 54 and the sliding groove 53, and the contact surfaces can be rapidly worn, so that the movement of the gland 4 is influenced, and the damping of the vibration effect is further influenced;
therefore, the oil storage groove 55 is arranged at a position close to the lower side in the sliding groove 53, when the lubricating oil flows downwards, the lubricating oil can be contacted with the upper top surface of the oil suction sponge 551 in the oil storage groove 55, the top surface of the oil suction sponge 551 is exposed outside the pressing plate 555, and the lubricating oil can be directly contacted with the oil suction sponge 551 body and absorbed; the hole groove structure can be uniformly arranged on the top surface of the oil suction sponge 551, so that downward flowing lubricating oil is convenient to flow in, and the contacted lubricating oil is further promoted to be absorbed by the oil suction sponge 551;
when the limiting block 51 moves downwards to the position where the oil storage groove 55 is located, the sliding block 54 moving downwards along the sliding groove 53 is contacted with the pressing plate 555 on the front position of the oil absorption sponge 551, the surface of the arc-shaped pressing plate 555 guides the sliding block 54 to smoothly move to the surface of the pressing plate 555, and meanwhile the pressing plate 555 is extruded, so that the pressing plate 555 is movably embedded into the oil storage groove 55, and the sliding block 54 smoothly passes through;
while the sliding block 54 smoothly passes through, the pressing plate 555 moves to squeeze the oil absorbing sponge 551 to deform, and a part of lubricating oil absorbed by the inside of the oil absorbing sponge 551 is squeezed and flows out and is blocked by the limitation of the arc-shaped pressing plate 555, so that the lubricating oil flows into the oil collecting cavity 552 through the uniformly arranged communication holes 557 on the partition plate 553, the extruded lubricating oil conveniently flows into the oil collecting cavity 552 from the large end part of the communication hole 557 with a larger opening because the communication holes 557 are conical holes, and then flows out through the small end part bit stream, and then is accumulated in the oil collecting cavity 552, and after the oil collecting cavity 552 is filled, the lubricating oil can enter the oil storage cavity 521 along the transmission channel 554 to supplement the lubricating oil in the oil storage cavity 521, so that the recycling of the lubricating oil is realized;
in order to make the circulation process more smooth, a micro oil pump can be arranged in the middle of the transmission channel 554, the oil pump is started by an outside controller, and the lubricating oil in the oil collecting cavity 552 is pumped out to enter the oil storage cavity 521 at the upper side through the transmission channel 554, so that the smooth realization of the recycling of the lubricating oil is ensured, the utilization rate of the lubricating oil is improved, the continuity of the lubricating effect is ensured, the number of times of manually adding the lubricating oil is reduced, and the maintenance cost is reduced.
