[0004] During the process of implementing this application, the inventor discovered that the prior art had the following problems: when the device is in use, although it can perform lubrication through the L-shaped infusion tube and the liquid outlet plate, the sprayed lubricating oil cannot enter the connection position between the damper and the door frame well, and will also pollute the surrounding environment.

[0005] Therefore, the present application provides an explosion-proof translational mining damper with a lubrication function to solve the problems raised in the above background technology. Utility Model Content
