Abstract

According to the technical scheme, the jack device is characterized in that the jack device comprises an outer cylinder and further comprises an inner cylinder which is vertically connected with the outer cylinder in a sliding mode; the screw rod is rotationally connected in the outer cylinder through a bearing, and the screw rod is in threaded connection with the inner cylinder; the power structure is used for driving the screw rod to rotate; the connecting disc is fixed at the bottom end of the inner cylinder; the pressing structure is arranged on the outer cylinder and used for pressing the outer cylinder to prevent the outer cylinder from sliding; and the lubricating structure is used for lubricating the screw rod along with the action of the power structure. When the jack device is used, the power structure drives the screw rod to rotate, the outer barrel is driven to slide outside the inner barrel, and the lifting function is achieved; in addition, the self-locking capacity of the jack can be improved by means of the pressing structure, and the screw can be alternately lubricated by means of the arranged lubricating structure when the power structure drives the screw to rotate.

Description

technical field [0001] The invention relates to the field of jacks, in particular to a jack device. Background technique [0002] Jack, it has two kinds of mechanical type and hydraulic type. The jack is mainly used in factories and mines, transportation, logistics and other departments as vehicle repair and other lifting, support and other work. Its structure is light and strong, flexible and reliable, and can be carried and operated by one person. Jacks are divided into mechanical jacks, hydraulic jacks, and pneumatic jacks, each with a different principle. In principle, the mechanical jack adopts the mechanical principle. It is common to pull the handle back and forth, pull the claw to push the ratchet to rotate, and the small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be lifted or lowered. , to achieve the function of lifting force. But not as simple as a hydraulic jack. The principle on which hydraulic jacks a...
