Abstract

The utility model discloses a rotary lifting chair. An upper and a lower rotating plates are arranged below a chair seat surface and a mechanism similar to few teeth difference transmission is arranged between the two plates. Under the function of orientating assistant of leg-foots, the rotating angle change produced by rotation between the upper and the lower rotating plates can be transferred to a supporting screw rod, and thus the screw rod can be rotated a corresponding angle relative to a screw nut sleeve. Thus movements of rising and falling can be completed. When a fixed target (such as a TV) is watched using the utility model, the orientation of the user body is fundamentally unchanged, and the rising and falling of the chair seat can be achieved without rising up. At the same time, the waist, legs, feet, the neck and eye parts of the user can be exercised, and thus the goals of body moving, fatigue relieving and health benefit can be achieved.

Description

A kind of rotation and lifting chair

The utility model relates to a kind of chair lift, particularly relates to a kind of seat that can make its rotation and lifting by the health twisting.

The chair lift that uses mainly is simple screw rod lifting form at present, its lifting action can only taken one's seat preceding or sit thereon with manually adjusting, and spinning movement is carried out separately with leg power, as is sitting on the chair, health then can't be realized the lifting of seat towards remaining unchanged.When watching fixed target (as seeing TV), can only be sitting on the seat of level altitude, fixed-direction, people's waist, knee, neck, eyes keep a posture for a long time, and are very easily tired.

It is a kind of under the constant substantially situation of the direction of taking one's seat that the purpose of this utility model is to provide, and realizes the rotation and lifting chair of rotation or lifting by the twisting of health.

In order to achieve the above object, the utility model has designed a kind of rotation and lifting seat, seat face and backrest use screw-driving on last swivel plate, the sphere pit is established at last swivel plate center, be supported on the spheric end centre strut, pillar is with being screwed at down on the swivel plate, there is a circle ball head column at the excircle place of following swivel plate, ball head column is fastened on down on the swivel plate, there is difference in the circle hole that its quantity and last swivel plate cylindrical place establish, and described swivel plate down and screw rod fix as one, and screw rod is threaded onto in the thread bush, thread bush is installed in the column of base, establish end plate in the screw rod lower end, to play the directed stabilization of part and the spacing safety effect that rises, end plate is divided into spring collar and is carried out axial location, a safety guard of limiting below the last swivel plate, safety guard is screwed with last swivel plate and is connected.

Advantage of the present utility model is:

1, uses the utility model, when human body is seated, need not stand up,, only can realize the lifting or the rotation of seat by the effect of the twisting of waist and legs and feet portion towards constant substantially.

2, in the lifting that realizes seat or when rotatablely moving; the waist of human body, legs and feet portion have obtained motion; when observing the fixing point target (as seeing TV, operation computer); the sight angle of its neck, eye all can have movable or change in various degree; thereby reach movable health, the purpose that protects the health.

3, widely applicable, be the health care seat, can be used as common seat again, its seat face and overall appearance can use different materials to make various different patterns, different class are widely used in family, office, public place of entertainment, bar desk, cashier, hotel, gymnasium etc.

Be described in detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the related rotation and lifting chair of the utility model.

As shown in Figure 1,1 is seat face and backrest, with screw 4 be tightened in swivel plate 2 above, the sphere pit is established at last swivel plate 2 centers, is supported on the spheric end centre strut 3, and pillar 3 usefulness are screwed at down on the swivel plate 7, there is a circle ball head column 13 at the excircle place of following swivel plate 7, ball head column 13 is fastened on down on the swivel plate 7, and there is difference in the circle hole that its quantity and last swivel plate 2 cylindrical places establish, forms the structure of similar few tooth difference transmission jointly.Following swivel plate 7 fixes as one with screw rod 8, screw rod 8 is threaded onto in the thread bush 9, and thread bush 9 is installed in the column of base 10, establishes end plate 11 in the screw rod lower end, to play the directed stabilization of part and the spacing safety effect that rises, end plate is divided into spring collar 12 and is carried out axial location.Be the globality and the security of assurance seat, the safety guard 6 of below last swivel plate 2, limiting, safety guard 6 is fixedlyed connected with last swivel plate 2 usefulness screws 5.

When human body is sitting on this seat, when health is done 360 ° of deflections around the seat vertical center line, compressing seat face 1 and last swivel plate 2 deflection together, the periphery circular hole of last swivel plate 2 will be by contacting with bulb pillar on the following swivel plate 7 successively along (contrary) clockwise, after rotating a circle, then produce a corner up and down between the swivel plate, thereby make the seat face rotate same corner, but because people's foot is in the support orientation on ground, can force and keep static relatively up and down between the swivel plate substantially, and make the screw rod 8 that links with following swivel plate change corresponding angle, thereby cause the lifting of seat in thread bush 9 inward turnings.When being sitting on the seat, when twisting health continuously, seat can carry out lifting continuously.In this process, the waist of human body, shank, foot, neck all can have certain action, and when observing a certain fixing point target, the angle of sight line just has certain variation, thus the effect of playing movable health, protecting the health.

Also few tooth difference structure realization of forming of few tooth difference structure such as available standards tooth, sawtooth, arc tooth or cycloid arc and bead of the mutual rotation of 2,7 of swivel plates up and down, its operating principle is identical therewith.

This rotary lifting chair be applicable to family, office, public place of entertainment, bar desk, The ground such as cashier, Hotels and Hostels, gymnasium use.
