The invention relates to the technical field of electric jacks, in particular to an impact-resistant motor home electric jack which comprises a base, a lifting frame is rotationally connected to the inner side of the top of the base, a top plate is mounted at the top of the lifting frame, a rotating rod is in threaded connection with the inner side of the lifting frame, and a positioning seat is mounted on one side of the rotating rod. A driving motor is installed on the positioning seat, supporting frames are installed on the two sides of the base, the tops of the supporting frames are rotationally connected with stretching cylinders, the interiors of the stretching cylinders are slidably connected with extending arms, and multiple sets of positioning grooves are formed in one sides of the extending arms; the problems that when the jack suddenly bears huge falling impact force, the borne load is too large, a motor cannot bear and is damaged, a top plate and a lifting frame lose supporting force, then the motor home rapidly descends, a vehicle body and the jack are damaged, the maintenance cost is increased, and safety is poor are solved.
本发明涉及电动千斤顶技术领域,具体涉及一种耐冲击的房车电动千斤顶,包括底座,所述底座顶部内侧转动连接有升降架,所述升降架顶部安装有顶板,所述升降架内侧螺纹连接有转动杆,所述转动杆一侧安装有定位座,所述定位座上安装有驱动电机,所述底座两侧均安装有支撑架,所述支撑架顶部转动连接有伸展筒,所述伸展筒内部滑动连接有延伸臂,所述延伸臂一侧开设有多组定位槽;本发明避免千斤顶突然受承受巨大的下坠冲击力时承重过大,电机无法承受并损坏,顶板与升降架失去支撑力,随之房车快速下降,导致车体和千斤顶损坏,增加了维修成本,安全性较差。
