The invention discloses an automobile jack tire jacking device cross-country rescue escape device, and relates to the technical field of jacks, the automobile jack tire jacking device cross-country rescue escape device comprises a frame and a jack main body, the jack main body is movably inserted into the bottom surface of the frame, the extending end of the jack main body is fixedly connected with a supporting plate, the top surface of the supporting plate is fixedly connected with a protective plate, and the protective plate is fixedly connected with a tire jacking device. The upper end of the protection plate is attached to the bottom face of the frame, a gear rod is rotatably connected to the side face of the protection plate, sliding grooves are formed in the left side and the right side of the supporting plate correspondingly, expansion plates are slidably connected to the inner walls of the sliding grooves, and double-thread rods are rotatably connected to the inner walls of the sliding grooves. Firstly, the gear rod is rotated to promote the double-threaded rod to rotate, so that the expansion plate is promoted to extend out from the interior of the supporting plate, the stress area of the supporting plate is increased, and the possibility that the supporting plate continuously sinks into mud when the jack body applies force to the supporting plate, and consequently wheels are difficult to move upwards is reduced.

    本发明公开了一种汽车千斤顶举顶胎器越野救援脱困装置,涉及千斤顶技术领域,包括车架与千斤顶主体,所述千斤顶主体活动插接在所述车架的底面,所述千斤顶主体的伸出端固定连接有支撑板,所述支撑板的顶面固定连接有护板,所述护板的上端与所述车架的底面贴合,所述护板的侧面转动连接有齿轮杆,所述支撑板的左右两侧均开设有滑槽,所述滑槽的内壁滑动连接有扩展板,所述滑槽的内壁转动连接有双螺纹杆。本发明首先通过旋转齿轮杆促使双螺纹杆旋转,从而促使扩展板从支撑板内部延伸出来并增加支撑板的受力面积,进而减少千斤顶主体对支撑板进行施力时支撑板不断陷入泥地内部并导致车轮难以向上移动的可能。
