Description
The utility model manual multifunctional chair lift belongs to chair, relates in particular to the chair that can regulate.
Industries such as medical treatment, haircut, office all have many chair lifts to be used for requirements of one's work.But chair lifts such as these are simple and easy, hydraulic pressure can not be at any time or simple in structure, the regulated at will lifting; Structure is too complicated, and assembly cost height is prone to fault, and maintenance is difficult for.
Chinese patent 89200349.9 has disclosed the chair lift of the pre-dynamic balance screw drive of a kind of load-carrying for this reason.This chair lift is at the lug of base and seat support platform between the two, be provided with upper and lower pole, between base and upper rack posts, be provided with the screw rod that drives by motor, be provided with pneumatic cylinder on upper rack posts top and lower fulcrum bar near the place, bottom again, the lifting of seat support platform and location, by motor to the driving of screw rod and realize.
This chair lift, the lifting and the location of adjusting seat support platform that can be easy, lifting is also very steady, but because this chair lift is provided with pneumatic cylinder, processing request precision height, maintenance also bothers, and need power supply, not having electricity, outage, be difficult for that power supply is installed, do not need can't use under many situations such as power supply, be difficult in vast basic unit and a lot of work and popularize.Moreover the minority chair kinds such as word that are only applicable to of this structure, function ratio is more single, and accommodation is less.
The purpose of this utility model provides a kind of being easy to and regulates and control, and the processing maintenance is all very convenient, does not need power supply, can popularize the multifunctional lifting chair that accommodation is wider in vast basic unit.
The purpose of this utility model is achieved through the following technical solutions:
This chair lift, by seat support platform assembly, the seat base assembly, transmission mechanism, turning cylinder, fixed axis, bearing is housed on the turning cylinder, be processed with the screw thread that can screw coupling mutually on turning cylinder and the fixed axis respectively, and compositions such as sleeve and various cranks, with the lifting and the location of manually easy realization seat support platform assembly.
The seat support platform that the utility model adopted, seat base assembly can be the different shape and the structure that have chair now, comprising the seat support of difformity structure, handrail, backrest, headrest support, pedal, support tube, frame, all and seat support platform and the seat base person of connecting as one such as castor.
Transmission mechanism by the pitch wheel group as: conical gear, worm gear, worm screw, helical gear and power transmission shaft etc. are formed.Can directly be assemblied in below the seat support of seat support platform assembly, but also peripheral hardware casing, support etc. again with seat support platform component assembling.
Turning cylinder and fixed axis both can be screw rod, also can be for propping up tube by a nut and a nut that tube is formed.
Minimum on the turning cylinder one group of bearing is housed, transmission mechanism driven pulley central authorities below the seat support are fixed in its upper end, and lower end and fixed axis screw with screw thread, and fixed axis is fixed in the correct position of seat base assembly.
Turning cylinder and fixed axis outside are equipped with sleeve, and its upper end can be fixed in below the seat support platform assembly, with the protection rotating mechanism, increase attractive in appearance.Also help and other seat assembly assembling.
This chair lift can use each pattern crank, but is preferably the various stealthy crank of the work of not influencing.As:
Can be equipped with on the turning cylinder by inside and outside sleeve pipe fit, the extension type of the outer head end pin lock knot of bayonet socket and power transmission shaft is arranged on the inner sleeve; Or the pin side of making into tenon, polygonal tenon etc., with sleeve pipe, the assembly phase interlocking knot of same shape; Also can make bushing type to power transmission shaft or the outside end of power transmission shaft, crank is made shaft type.Because this class crank is to make with sleeve pipe, lock construction spare etc., but direct-axis can push below the seat support platform assembly, so be called telescopic stealthy crank to sliding.
On the power transmission shaft, also can assemble the crank and the crank basal disc of various geometries, and crank is folding collapsible type invisible crank.Specifically: head end junction outside crank base portion or crank and turning cylinder, that design can prevent is suitable, reach the outer radial work done displacement of not tilting counterclockwise, the inside bearing of radial folding again, in turning cylinder or crank, also can assemble spring, and add compressing tablet between bearing, utilize the elastic force of spring, and stop the crank dislocation compressing tablet.Also can in bearing, add spring, rubber, elasticity of plastics sheet pad, prevent its dislocation.
Also can assemble the stealthy crank of the combined type that combines by above-mentioned two kinds of cranks on the power transmission shaft.
Outside the transmission mechanism of this chair lift, the pitch wheel group, preferably be equipped with the casing of required different shape and structure, as: square, circular, lid, uncovered, band turning joint etc. are arranged.
Lower box can assemble the Suresh Kumar sleeve, and making the two with screw, screw, annular groove etc. is fixing or 360 degree rotational slides connections.
The sleeve that assembles on the casing is sleeved on the fixed axis, and making the two is that lifting is slidingly matched, and can be made into lifting and equal simple type chair lift very stably when using.
Sleeve also can assemble with the mutual fit of support tube, frame on the seat base assembly, can directly contact cooperation between the two; Also available key, keyway control rotation cooperate; Or cooperate with contact of key, keyway and control rotation.
The seat support platform assembly of sleeve upper end can the rotary-type chair of 360 degree, and seat support platform assembly and case spare one side can have a regulating screw, by its precession or revolve and move back, whether its head end is compressed, to reach the purpose of whether controlling its rotation with sleeve upper end outer wall.
Regulating screw, also seat assembly pitch angle degree such as adjustable backrest.Whether at this moment, the control lever of seat assembly pitch angle degree such as backrest can pass the regulating screw head end of casing or casing one side, according to compressing, to reach the purpose of regulation and control.Also can be pressed on sleeve upper end outer wall again, face upward and bow and two kinds of purposes of seat support platform assembly rotation to reach seat assemblies such as regulation and control backrest by control lever.
One turning joint and stop assembly for 360 degree rotations such as seat support platform assemblies can be arranged on the support tube.
This manual multifunctional chair lift, owing to bearing is housed on the turning cylinder, rotate very lightly, transmission mechanism is provided with casing outward, be more convenient for processing and assemble with multiple seat assembly, can be made into the chair lift of multiple structure, and simple in structure, use, easy to maintenance, do not need power supply, accommodation is wider, can popularize in vast basic unit, can satisfy advantages such as multiple concrete need of work multi-level, conglomerate.
