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 meet life andRequirements of one's work. As being contained in the small-sized lowering or hoisting gear on tables and chairs, bed cabinet, drawing table, it canRegulate according to people's height, thereby bring great convenience to people's live and work.Existing lowering or hoisting gear kind is more, and a class is by hydraulic pressure or air pressure (as pressure liftable chair)Drive piston rod to carry out lifting, this class device has easy to adjust, labour-saving advantage, stillBecause sealing effectiveness is bad or use for a long time, easily there is pressure leakages situation in this class device,Cause in use after raising again landing automatically and shortcoming that can not lifting; Some pneumatic literFall seat explosion accident also occurred. Another kind of is to come by the spiral lift device of worm and gearThe height that regulates lifting, it has solved above-mentioned lowering or hoisting gear and has easily occurred pressure leakages situation, makesBecome after in use raising again automatically landing and problem that can not lifting, but this worm gearThe lowering or hoisting gear of worm screw 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, regulates highly just several centimeters, if Granted publication day is 2001In on December 26, in, Granted publication number is that the patent of invention of CN2466972Y just belongs to this type of. AlsoHaving a class is Motorized lift device, and it has easy to adjust, advantage fast, but it hasCost is high, hold flimsy shortcoming, and particularly it must use power supply, there is no power supply or confessionThe inconvenient place of electricity just cannot lifting, and therefore 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, provides a kind of lightSeat riser, 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 in a hollow column and activityPipe, the upper end of hollow column is fixed with seat holder, under seat holder, is fixed with handle, and its feature existsIn: the bottom of hollow column is fixed with spring, and the centre of hollow column is inserted with locking bar, on locking barBe provided with retainer, the locking bar of retainer bottom inserts the centre of spring, and on retainer, cover has nylon watt cover,On locking bar, to have inner tube, the bottom of inner tube be taper to cover, and the bottom of inner tube is inserted in nylon watt coverBetween.
The good technical scheme of the present invention is: the bottom of described nylon watt cover is provided with draw-in groove, Buddhist nunDragon watt cover engages with retainer by draw-in groove. A described nylon watt cover is by 2-4 sheet arc shaped tile cover groupClose and form a circle watt cover.
Operation principle of the present invention is: lift handle force locking bar and retainer drive nylon watt cover toLower motion, departs from taper inner tube and remove the locking state between hollow column tube wall, liftingHeight can free adjustment, be adjusted to proper height, release handle, at the elastic force of springUnder the double action of seat gravity, taper inner tube by nylon watt cover distending, tightly props up sky againThe tube wall of heart 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.

Detailed description of the invention
As shown in Figure 1, the present invention includes a hollow column 1 and movable internal pipe 8, hollow verticalThe upper end of post 1 is fixed with seat holder 5, and seat holder is fixed with handle 10 5 times, hollow column 1Bottom be fixed with spring 3, the centre of hollow column 1 is inserted with locking bar 2, locking bar 2 is provided withRetainer 4, the locking bar of retainer 4 bottoms inserts the centre of spring 5, and on retainer 4, cover has nylon wattCover 6, on locking bar 2, to have movable internal pipe 8, the bottom of movable internal pipe 8 be taper 9 to cover, activityTaper 9 partial insertions of inner tube bottom are in the middle of nylon watt cover 6. The end of described nylon watt coverPortion is provided with draw-in groove 7, and a nylon watt cover 6 engages with retainer 4 by draw-in groove 7. As Fig. 2 and Fig. 3Shown in, a described nylon watt cover 6 is to combine a circle watt cover by four arc shaped tile covers.
