Abstract

The utility model discloses a chair with massage device which can not only be used as a sofa seat, but also can be used as a pounding back massage therapy. The chair with massage device is composed of a sofa chair whose angle between a back board and a sitting board can be adjusted and a set of electrical pounding back device which is arranged on the back board. The back of the user sitting on the chair can be pounded and massaged by a worm wheel-worm screw retarding mechanism, a reciprocating screw rod elevating mechanism, a gear drive mechanism, a crank link mechanism and a flexible hammer which are driven by a miniature electric motor. The utility model has the advantages of simple structure, convenient operation, and comfortable pounding.

Description

Chair with massage device

But this utility model relates to a kind of furniture of double as physical therapy.

People use stool, chair, sofa always as the instrument that is seated and has a rest, but this instrument can only be removed the fatigue of legs and feet, can't eliminate the fatigue at back and the pain at some position, back, for this reason, someone had once designed a kind of masseur that the sofa back is housed, No. 87211158 utility model patents of China, a kind of knocking formula electric massage sofa is also disclosed, but this Massage sofa need use two motor, thereby cost is higher, and the fixed angle of backboard and seat is constant, thereby it is also comfortable inadequately to sit up.

Task of the present utility model is the deficiency that will overcome existing sofa and above-mentioned electric massage sofa, designs a kind of simple structure, comfortable electronic Back thrasher chair with electric or magnetic drive easy to use.

Task of the present utility model is done in such a way that fixes a cover electric back-pounding device on the backboard of the couch of the adjustable angle between backboard and seat.This electric back-pounding device is driven by a micromotor, pass through turbine and worm decelerator, the reciprocating screw reciprocating mechanism, gear drive, toggle drive two groups of flexible hammers moving up and down and finish the knocking at seat person back massage, it are eased the pain or allaying tiredness.Because the power that is used to pound one's back can not be too big, thereby all available plastic pressure injection molding of most of part of the present utility model, with weight reduction and manufacturing cost, because this utility model only uses a motor, and the angle of backboard and seat can be regulated, thereby not only structure is simpler, and cost is low, and use is also more convenient, and it is also more comfortable to pound one's back.

Describe below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the view that Back thrasher chair with electric or magnetic drive of the present utility model is seen from the side, Fig. 2 be its A to view, Fig. 3 is that B is to view.

With reference to accompanying drawing, the seat 1 of Back thrasher chair with electric or magnetic drive of the present utility model is the couch that has seat 11, backboard 12, handrail 13 and chair foot 14, regulating tank 15 is arranged on the handrail 13, there is splicer 16 junction with backboard 12 on the seat 11, also have clamping screw 17 on the backboard 12, they can be in order to regulate the angle of backboard 12 and seat 11.Be fixed with a cover electric back-pounding device on backboard 12, this device is made up of a micromotor 2, turbine and worm decelerator 3, reciprocating screw reciprocating mechanism 4, gear drive 5, toggle 6 and flexible hammer 7.Micromotor 2 is fixed on the carriage 8, and turbine and worm decelerator 3 comprises and an affixed worm screw 31 of motor 2 and the worm gear 32 affixed with reciprocating screw 41 lower ends." nut " that cooperate with reciprocating screw 41 in the reciprocating mechanism 4 is to be fixed on the stylus pin 42 that stretches on the balladeur train 43 in the reciprocating screw helicla flute.Gear shaft 51 and the toggle 6 and the flexible hammer 7 of gear drive 5 also are installed on balladeur train 43.Driven wheel 52 in the gear drive 5 and idler gear 53 are installed in the bottom of reciprocating screw 41.Toggle 6 is by forming with the affixed driving gear 61 in gear shaft 51 upper ends and two crank gears 62 and two connecting rods 63 that are engaged with, the hammer stem 71 of two flexible hammers 7 respectively with two connecting rods 63 hinged and can be on balladeur train 43 left and right sides slippage flexible.Tup 72 is surrounded by the soft hammer of foam rubber cushion layer and skin overcoat outward for skeleton.

This Back thrasher chair with electric or magnetic drive can be used as common couch at ordinary times and sits idly for the people, when pounding one's back, as long as energized, micromotor 2 just drives worm screw 31, worm gear 32, reciprocating screw 41 rotates, drive idler gear 53 by the driven wheel 52 that is fixed on reciprocating screw 41 bottoms then, gear shaft 51 rotates, the driving gear 61 that is fixed in gear shaft 51 upper ends drives two crank gears 62 again and drives flexible hammer 7 by connecting rod 63 and seesaws, the person's that beats the seat back, simultaneously, rotation along with reciprocating screw 41, what engage is fixed on stylus pin 42 on the balladeur train 43 and will promotes balladeur train 43 and move back and forth up and down, thereby flexible hammer 7 is also moved up and down, so that change the position of pounding one's back.
