The invention discloses a chain block with a sealing lubrication device. The chain block comprises a chain block body and comprises a sealing outer cover, a partition plate, retracting and releasing holes and sealing pads, the sealing outer cover is located on the outer side of the chain block body, and the sealing outer cover and the chain block body are connected in a welded mode; the partitionplate is located at the bottom of the sealing outer cover, and the partition plate and the sealing outer cover are connected in a welded mode; and the retracting and releasing holes are located in thebottom of the partition plate and are a plurality of circular through holes, the sealing pads are located at the centers inside the retracting and releasing holes and are each in a cylindrical shape,and the sealing pads and the retracting and releasing holes are connected in a glued mode. According to the chain block with the sealing lubrication device, the sealing outer cover is welded to the outer wall of the chain block body firstly, and the chain block body is filled with lubricating oil, so that all parts are fully lubricated, the problem of incomplete traditional lubrication is fundamentally solved, the lifting smoothness of the chain block is greatly improved, and the jamming phenomenon is avoided.
