Abstract

The utility model refers to an electric massage chair which can give a longitudinal rolling kneading massage along the necks, the waists and the backs of human bodies. The utility model is mainly characterized in that a frame is arranged on a chair back plate; a screw rod driven by a worm gear is arranged on the frame; a machine frame which is provided with a nut on the upper end and a cylindrical cam on the inner part is arranged on the screw rod; a sliding key clamped in a slide way of a key groove of the screw rod is arranged on the cam. When the screw rod rotates, the machine frame moves on the screw rod. The cylindrical cam moves along the machine frame and rotates along with the screw rod; the rotation of the cam push a pin rod and a twisting shaft of the pin rod to make a linear reciprocating motion. The pin rod also drives a bent shaft on a crank shaft and a massage ball to give a rolling kneading massage for the human bodies.

Description

Electric massage chair

This utility model belongs to the chair tool.

In daily life work, there is cervical region in people regular meeting, uncomfortable and the ailing situation of lower back, this is relevant with some physiological decease of human body on the one hand, also lack health care on the other hand and sport and body-building is relevant with human body, therefore both at home and abroad all begin to have paid attention to research to the massage armchair tool, Chinese patent " manual massaging health-care chair; the patent No. 942436032 " is because its massage wheels only can be made horizontal roll and massage to human waist and back, and the meridian point of human waist and back mainly is vertical arrangement along the human vertebra both sides, so its massaging way does not meet the human physiological structure; Chinese patent " manual electronic massaging health-care chair; the patent No. 942436024 " has adopted massage wheels that human waist and back is made the longitudinal rolling massaging way, overcome the shortcoming and defect of front patent, but, therefore can not satisfy the needs of people fully to therapeutic massage because its roll and massage mode is comparatively single.

The purpose of this utility model provides a kind of electric massage chair, and it can simulate people's finger cervical region, the lower back of human body are being done to have the kneading massage action concurrently when longitudinal rolling is massaged.

The purpose of this utility model is achieved in that comprising seat support, chair lower limb, the chair back and comfort on the chair back plate of electric massage chair of hands and is provided with a framework of placing vertically, framework has plate behind top board, base plate, left plate, right plate, left front baffle plate, right front baffle plate and the framework, whole framework one firmly connects, and the back plate of framework is fixed on the chair back plate by screw etc.; On frame head plate, be provided with bearing block, fastening or be welded on the top board by the spiral shell select; Be provided with reduction box on the base plate in the framework biside plate, the base of its case is fixed on the chassis base by the spiral shell select; Be provided with a rotating motor on the base plate in the framework side plate outside, its end cap is fixed by the spiral shell select by side plate reserved opening and reduction box, and its middle part that enters the motor shaft extension of reduction box is connected and fixed with worm screw by key pin etc.; In frame head plate bearing block and reduction box top bearing seat, be provided with a screw rod with axial keyway slideway, its two ends can be dynamically connected by bearing and top board bearing block and reduction box top bearing seat, and it reaches on the screw rod shaft extension in the reduction box by key pin etc. and is connected and fixed with worm gear; On screw rod, be provided with a frame, the upper end of frame have one with the mutual meshing nut of screw rod, central rack has a housing, the housing front has a saturating groove of rectangle, back side of shell has a transverse axis, and the housing both sides respectively have a vertical shaft sleeve, and nut, housing, transverse axis and shaft sleeve four member one firmly connect, be provided with an end cap in the lower end of frame, be connected and fixed with housing by spiral shell select etc.; Be provided with the cylindrical cam movable sleeve that an internal diameter has feather key and be connected on the screw rod in the frame housing, the feather key on it movably is stuck in the screw rod keyway slideway, and the cam both ends of the surface movably are stuck between intravital nut of shell and the end cap; Respectively be provided with a bottom has vertical shaft, middle part and has the member crank axle that pin pipe, top have cambered axle at two vertical shaft sleeve places of frame housing both sides, three member one firmly connect, and the vertical shaft of its underpart movably is assemblied in the vertical shaft sleeve by pin or back-up ring; About two pins respectively be provided with a pin rod in the pipes.The mutual hinge in two pin rod inner ends connects; Being provided with a roller that movably connects (or slide block) on the shaft extension below two pin rod twisted axis extend in the groove slideway of cylindrical cam in the housing from the saturating groove of housing square type; Be provided with massage ball (or wheel) in the upper end of cambered axle, can be dynamically connected by axle bush back-up ring etc. mutually; Respectively be provided with a movable belled roller (or slide block) at the two ends of transverse axis; Be provided with manual electric switch of button and signal lights thereof in the chair back one side (or comforting on hand); On the top board bearing block, be provided with the upper limit micro limit switch; On reduction box top bearing seat, be provided with the lower limit micro limit switch; On the chair back plate of motor one side, be provided with the electromagnetic switch plate; Be provided with spongy body on chair back plate around framework and the front apron; Outside said mechanism, be provided with the chair cover.Like this, as long as people are sitting in the close chair back of health on the seat support in the time of need massaging, the energized plug touches the button (up button or descending button) on the motor manual switch, rotation through the screw rod after the worm and gear deceleration, axially move on screw rod with the meshing nut of screw rod on promptly can drive chassis, frame also moves on screw rod thereupon, the intravital cylindrical cam one side of frame shell is moved with frame, one side is also rotated with screw rod, the rotation of cam promotes, spurred roller below the pin rod twisted axis in its groove slideway along the reciprocal straight line axially-movable of the saturating groove of housing rectangle (guide rail), the motion of twisted axis makes pin rod constantly be pushed in the pin pipe again to pull out and constantly the cambered axle above the area untie-sell pipe and massage ball (or wheel) are that the camber line reciprocally swinging is made in the axle center with the vertical shaft in the shaft sleeve, because the direction of housing both sides cambered axle swing is opposite relatively, therefore just realized of the rolling kneading massage action of the massage ball (or wheel) of its cambered axle upper end to human body; When the two ends that frame moves to screw rod touched the upper limit micro limit switch that is located at the top board bearing block or the lower limit micro limit switch on the reduction box top bearing seat, motor was with the automatic reverse reverse rotation, and frame also will oppositely move massage thereupon.

Because what this utility model adopted is the motor machine transmission scheme, so its automaticity increases than armstrong's patent transmission massage armchair, because this utility model is to make the longitudinal rolling kneading massage along human body back vertebra both sides to the massaging way of human body, therefore on the basis that meets human physiological structure's characteristics, can satisfy the needs of human body preferably again to therapeutic massage.
