Abstract

The invention discloses a jack with an anti-toppling structure. The jack comprises a base, wherein first rotating shafts are movably mounted on the side surface of the base, each bottom arm rod movably sleeves the outer side of the corresponding first rotating shaft, each connecting rod is fixedly connected to the part, located below the interior of the base, of the corresponding bottom arm rod, and each rubber ball seat is fixedly connected to the bottom of the corresponding connecting rod; and rubber bottom plates are fixedly bonded to the bottom of the base, each movable seat is movably mounted at the top of the corresponding bottom arm rod, each upper arm rod is movably mounted on the inner side surface of the corresponding movable seat, and a lead screw is mounted on the side surfaces of the movable seats in a threaded mode. According to the jack, a side connecting base and the connecting shafts are arranged and cooperate with a first side supporting rod, a second side supporting rod and a tension spring, so that the side surface of the jack can be jacked up in the using process of the jack, it is guaranteed that when the jack inclines in the using process, the jack topples over, and further the problem that the jack topples over in the using process, and the object suddenly falls off and is damaged, is solved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a jack with an anti-dumping structure. Background technique [0002] The jack refers to a light and small lifting device that uses a rigid lifting piece as a working device, and lifts heavy objects in a small stroke through the top bracket or bottom claw. The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and For other lifting, supporting and other work, its structure is light and firm, flexible and reliable, and can be carried and operated by one person. [0003] The jacks currently used generally have hydraulic jacks or simple rack jacks, which only play a situation of up and down movement in the process of using, and then the device is jacked up. There are manual jacks and automatic jacks. [0004] At present, during the use of this kind of jack, it may be dumped due to the action of the lifted object, and then the object wi...
