[0002] The guide rail is one of the chain guides. The chain guide rail is also called the chain guide chain and the chain track. It is used to support and guide the chain. In the existing chain transmission system, in order to prevent the chain from sagging due to gravity, the chain is usually installed on the guide rail to prevent the chain from sagging and to limit the chain. However, the chain works in the guide for a long time, which causes friction between the chain and the inner wall of the guide for a long time, thereby reducing the service life of the chain.

[0003] To solve the above problems, the prior art patent (CN219221173U) discloses a chain guide, which is equipped with a lubrication device to push the push rod to move the sealing block. When the sealing block moves into the hole, the hydraulic rod is pressurized. When the hemispherical block moves into the hemispherical groove, the hydraulic rod is reset to clamp the hemispherical block into the hemispherical groove. As a result, the sealing block is not sealed against the oil outlet pipe, and the lubricating oil flows out through the oil outlet pipe to apply lubricating oil to the chain to prevent the chain from being shortened in service life due to long-term friction between the chain and the inner wall of the slide groove.
