High-speed servo system of car lifting jack

Abstract

The utility model relates to the technical field of car lifting jacks, and discloses a high-speed servo system of a car lifting jack, which comprises an assembly frame module, a servo control module assembled at the top of the inner side of the assembly frame module, a bearing module assembled at the bottom of the servo control module, and assembly mechanisms assembled between the servo control module and the bearing module as well as between the servo control module and the assembly frame module, the hollow cylinder is sleeved with a limiting disc, a torsional spring is connected to the outer portion of the limiting disc, clamping grooves are evenly distributed in the hollow cylinder, and a short arm is slidably connected to the inner portion of the hollow cylinder. According to the high-speed servo system of the car lifting jack, rotation of the assembling mechanism is automatically limited through the additionally-arranged torsional spring when the assembling mechanism is locked, so that the stability of the assembling mechanism in the using process is improved, the situation that the assembling mechanism relieves locking of a device in the using process is avoided, and through the additionally-arranged pop-up plate, when fixing of the device is relieved, the assembling mechanism is prevented from being unlocked. And the device can be quickly popped out, so that the smoothness of the device during disassembly is improved.
