Description
Technical field
The utility model relates to a kind of lifting mechanism, especially can strengthen the Long Distances lift jack of lifting stroke.
Background technology
At present, known lifting mechanism due to lifting stroke less, therefore its Applicable scope is less.
Summary of the invention
In order to overcome the less deficiency of its lifting stroke of existing lifting mechanism, the utility model provides a kind of Long Distances lift jack, and this Long Distances lift jack by strengthening lifting stroke, thus expands the Applicable scope of lifting mechanism.
The utility model solves the technical scheme that its technical matters adopts: the utility model comprises cover plate, top, carrying cylinder, joint plate, drive spindle, rocking handle, bolt hole, lifting arm, position-limited trough and lead key.Cover plate is the slab construction of annular arrangement, and the hole wall of cover central hole is provided with lead key.Joint plate is the slab construction of annular arrangement, and the centre hole of joint plate is set to dextrorotation thread pore structure, and the annular plate surface of joint plate evenly offers several bolts hole.Carrying cylinder is columnar structured, and cover plate is connected to the upper end of carrying cylinder, and joint plate is connected to the lower end of carrying cylinder, and the dextrorotation tapped bore of the endoporus of carrying cylinder and the centre hole of cover plate and joint plate is in same axis.Drive spindle is columnar structured, the outer tube wall of drive spindle is set to the helicitic texture closed with the dextrorotation corresponding threaded holes on joint plate, the endoporus of drive spindle is set to derotation thread pore structure, the upper end of drive spindle is threaded with the dextrorotation tapped bore of joint plate, and the lower end of drive spindle is connected with rocking handle.Top is for disc-shaped structure, and lifting arm is derotation bolt structure, and the derotation corresponding threaded holes in lifting arm and drive spindle closes, and the stud wall of lifting arm offers longitudinal position-limited trough.Lifting arm is arranged in carrying cylinder, and the centre hole that the upper end of lifting arm stretches out cover plate is connected with top, and the position-limited trough on lifting arm coordinates with the lead key on cover plate, and the lower end of lifting arm is connected in the derotation tapped bore in drive spindle.
In using, joint plate is connected on building by bolt hole, the top of lifting arm is corresponding with by lifting object, by rocking handle rotation of drive rod, when drive spindle is along dextrorotation tapped bore spiral on joint plate, derotation tapped bore in drive spindle can drive lifting arm to rise along on the direction that lead key and position-limited trough limit, and therefore promotes by lifting object.Rotate backward rocking handle, when drive spindle declines along the dextrorotation tapped bore spiral on joint plate, the derotation tapped bore in drive spindle can drive lifting arm to decline along the direction that lead key and position-limited trough limit, and therefore puts down by lifting object.
The beneficial effects of the utility model are, by strengthening lifting stroke, thus expand the Applicable scope of lifting mechanism.
