Propping device of overlong rotary handle

Abstract

The invention relates to a propping device, in particular to a proper comprising an overlong rotary handle and an overlong main body shell and having a special application function. The propping device consists of a base module and a propping module, and specifically comprises 33 components of a lower end cover, a bottom plate, an inner gasket, an inner end cover, a shell seat, a sliding bearing, an upper end cover, an outer gasket, an outer end cover, a bottom plate bolt gasket, a six-arris top column, a lower rolling bearing, a reversing screw tube, an upper rolling bearing, a top column limiting retaining disc, a top seat, a handle fastening nut, a handle, a handle turntable, an outer rolling bearing, a handle connecting rod, an inner rolling bearing, a bevel gear, a gear shaft pin and the like. The propping device overcomes the defects of more optional equipment, large occupied space, narrow adaptation range and the like in the conventional well-known propping device, and has the characteristics of simple and strong structure, convenience for use, overlong stroke, wide adaptability and the like; moreover, the propping device disclosed by the invention is simply implemented and easily manufactured, is attractive, decent, solid and durable, and has a wide market space and a high economic added value.

Description

technical field [0001] The invention relates to an abutment device, in particular to an abutment device with a special application function which adopts an extra-long main body shell and an extra-long handle. Background technique [0002] The ejector, also known as "thrust device" and "resistance device", refers to a mechanical device that can push from one fixed position to another direction. The distance between work pieces, or the lifting or lowering of some kind of object on a specific datum. [0003] Currently known jacks include hydraulic jacks, jacks, etc. Although these jacking devices have certain functions of jacking, pushing, and lifting, most of them have a round structure, and there are certain gaps in their lifting stroke and power transmission. Due to the limitation, it cannot play its due propulsion function in a narrow and long environment and in a flat environment, and it is difficult to adapt to the jacking and lifting needs of high-altitude operations an...
