Furthermore, the plug comprises a fixing screw and a rubber plug, the fixing screw is fixedly screwed in the flow channel and sleeved with the rubber plug, and the rubber plug seals a gap between the fixing screw and the flow channel. The fixing screw is used as a solid structure to be fixed at the outer end of the flow channel, the rubber plug improves the sealing property, and the pressure maintaining property of the structure is maintained.
Furthermore, there is the sclerosis layer on the surface of rolling element, and the outward appearance on sclerosis layer directly contacts with the working face of guide shoe. The hardened layer can prolong the service life of the rolling body and reduce the abrasion.
Furthermore, a sealing rubber ring is arranged on the edge of the flow channel at the outer end of the segmented structure of the elevator guide rail and tightly pressed on the outer end face of the segmented structure. Gaps are reserved among the segments, and pressure is kept through the sealing rubber rings.
Compared with the prior art, the utility model, have following advantage and effect: the device is used for an elevator running at high frequency, has an elevator guide rail structure with high-frequency lubrication requirement, reduces friction by arranging corresponding flow passages in the guide rail of the elevator and arranging the rolling bodies in the flow passages, and improves the smoothness of running by taking lubricating grease out through the rotation of the rolling bodies; meanwhile, the conventional oil injection structure is reduced, the guide shoe structure is simplified, lubricating grease can be supplemented in time by matching with one liquid pump, and smooth operation is ensured.
