Described mechanism also comprises a power transmission shaft, and it is axially vertical with described screw axial, and establishes a three cylindrical helical gear that meshes with described first cylindric spiral gear in an end, and respectively is convexly equipped with a short column body in the both ends of power transmission shaft.Described first cylindric spiral gear and the second cylindric spiral gear mate are coated by a box body, and described each short column body that combines with movable handgrip protrudes in described box body appearance.The other end of described couple axle is installed a contour identical transmission device.The described three cylindrical helical gear and first cylindric spiral gear, the second cylindric spiral gear mate are coated by a box body, and the short column body that each combines with flexible handle protrudes in the box body appearance.Both axially mutually vertical of described power transmission shaft and couple axle.
Compared with prior art, the utility model has the advantages that:
1, this furniture elevating mechanism is to be combined by cylindric spiral gear, and there is the engagement of two teeth its engagement place, thereby is difficult for collapsing tooth because of external force causes, and does not also need just can get higher capacity via strengthening gear material intensity.
2, this furniture elevating mechanism is to combine via three cylindric spiral gears, and its stability improves, and is difficult for causing eccentric phenomena; And during assembling, do not have the problem of tolerance phenomenon to produce, also can when rotating, not produce noise.
3, its flexible handle can be forwardly, rear, side and top carry out lifting control, can select one the direction of the suitable application of force rotate, can avoid causing puzzlement because of spatial constraints.
4, by the prolongation of couple axle, establish a transmission device again, but make two groups of furniture lifting structure synchronization liftings, also can increase the size of carrying furniture in the other end, and the position of operation lifting.
