Disclosed is a segmented inverting cover plate apparatus for an underfloor vehicle lifting jack. The apparatus comprises a cover plate, the cover plate being of a segmented structure, comprising a first movable cover plate (4) and a second movable cover plate (6), wherein the first movable cover plate (4) and the second movable cover plate (6) are hinged by means of a pin shaft. An anti-inversion block (5) is provided directly below the pin shaft, the anti-inversion block (5) being connected to the first movable cover plate (4) by means of the pin shaft. A guide wheel (7) is provided below the end of the second movable cover plate (6) away from the first movable cover plate (4). An inverting arm (3) is provided below the first movable cover plate (4), one end of the inverting arm (3) is connected to the anti-inversion block (5) by means of a bearing, the other end is connected to a powered push rod (1) by means of the pin shaft and an oil-containing bearing, and the powered push rod (1) is installed on a powered push rod mounting seat (2). The advantages of the present invention are: 1. in the course of overhauling, the lifting of a jacking element does not need to open the inverting cover plate; 2. after being closed, the first movable cover plate will not occupy the limited overhauling space, reducing safety risks for personnel performing the overhaul; and 3. various models of vehicle lifting element can be used. |
