Abstract
The invention relates to a lifting device, in particular to a lightweight seat lifting mechanism. The lightweight seat lifting mechanism comprises a hollow upright post and a movable inner pipe, wherein a seat plate support is fixed to the upper end of the hollow upright post; a handle is fixed below the seat plate support. The lightweight seat lifting mechanism is characterized in that a spring is fixed to the bottom of the hollow upright post; a lock rod is inserted into the center of the hollow upright post; a lock ring is arranged on the lock rod; the lock rod on the lower part of the lock ring is inserted into the center of the spring; a nylon tile sleeve is sleeved on the lock ring; the inner pipe is sleeved on the lock rod; the bottom end of the inner pipe is conical; the bottom end of the inner pipe is inserted into the center of the nylon tile sleeve. The lightweight seat lifting mechanism has the advantages of simple structure, labor conservation in adjustment, safety in use and convenience in installation.
Description
Technical field
The present invention relates to a kind of lowering or hoisting gear, particularly a kind of slideover seat elevating mechanism.
Background technology
In daily life, people often need a kind of light lowering or hoisting gear to meet the needs of live and work.As being contained in the small-sized lowering or hoisting gear on tables and chairs, bed cabinet, drawing table, it can regulate according to people's height, thereby brings great convenience to people's live and work.Existing lowering or hoisting gear kind is more, one class is to drive piston rod to carry out lifting by hydraulic pressure or air pressure (as pressure liftable chair), this class device has easy to adjust, labour-saving advantage, but this class device is because sealing effectiveness is bad or use for a long time, easily there is pressure leakages situation, cause in use after raising again landing automatically and shortcoming that can not lifting; Also there is explosion accident in some pneumatic lifting armchair.Another kind of is by the spiral lift device of worm and gear, to regulate the height of lifting, it has solved above-mentioned lowering or hoisting gear and has easily occurred pressure leakages situation, cause in use after raising again landing automatically and problem that can not lifting, but the lowering or hoisting gear of this worm and gear has the shortcoming that adjusting is relatively required great effort, cost is high, and efficiency is low especially, often worm and gear rotates tens circles, regulate highly just several centimeters, if Granted publication day is December 26 calendar year 2001, Granted publication number just belongs to this type of for the patent of invention of CN2466972Y.Also having a class is Motorized lift device, it has easy to adjust, advantage fast, but it have cost high, hold flimsy shortcoming, particularly it must use power supply, there is no power supply or the inconvenient place that powers just cannot lifting, so its scope of application is also restricted.
Summary of the invention
The object of the present invention's invention is exactly the defect for existing lowering or hoisting gear, and a kind of slideover seat elevating mechanism is provided, and it has solved, and existing seat elevating gear adjusting is relatively required great effort, cost is high, hold flimsy problem.
Technical scheme of the present invention is achieved in that it comprises a hollow column and movable internal pipe, the upper end of hollow column is fixed with seat holder, under seat holder, be fixed with handle, it is characterized in that: the bottom of hollow column is fixed with spring, the centre of hollow column is inserted with locking bar, locking bar is provided with retainer, the locking bar of retainer bottom inserts the centre of spring, and on retainer, cover has nylon watt cover, and on locking bar, cover has inner tube, the bottom of inner tube is taper, and the bottom of inner tube is inserted in the middle of nylon watt cover.
The good technical scheme of the present invention is: the bottom of described nylon watt cover is provided with draw-in groove, and nylon watt cover engages with retainer by draw-in groove.A described nylon watt cover is to combine a circle watt cover by 2-4 sheet arc shaped tile cover.
Operation principle of the present invention is: lift handle and force locking bar and retainer to drive a nylon watt cover to move downward, depart from taper inner tube and remove and hollow column tube wall between locking state, the height of lifting can free adjustment, be adjusted to proper height, release handle, under the elastic force of spring and the double action of seat gravity, taper inner tube is again by nylon watt cover distending, tightly props up the tube wall of hollow column and self-locking.
That the present invention has advantages of is simple in structure, it is laborsaving to regulate, use safety, easy for installation.
