Description

Collapsible massage armchair

This utility model relates to the collapsible massage armchair that a kind of health care is used.

In, doctor trained in Western medicine is thought that a lot of important acupuncture points are arranged in the vertebra both sides of human body, accounts for 70% of the main acupuncture point of whole body.Vertebra is the passage of nervus centralis contact whole body stolen goods internal organs organ, and the massage that is tantamount to stolen goods internal organs organ is often massaged in the vertebra both sides, can play prevent and cure diseases, the effect of building body body.Yet present various small-sized masseur all can not effectively be massaged the human vertebra both sides, though and the massage armchair massage effect of large-scale sofa-type is good, cost an arm and a leg, floor space is big, can't popularize.

The purpose of this utility model provides a kind of can effectively the massage the human vertebra both sides, and when not using collapsible again, floor space is little, and cost is low, is fit to enter the collapsible massage armchair of popular family.

The purpose of this utility model is achieved in that with metal tube makes a seat support, seat support and back leg are one, make a chair back again with metal tube, the chair back and preceding chair lower limb also are one, the chair back and seat support intersect to be installed, intersection at the both sides metal tube, respectively penetrate a bearing pin, the seat support and the chair back are fused, and the left and right sides of pro-chair lower limb is individual with the fixing last location-plate of bearing pin, and an alignment pin respectively is installed in the back leg corresponding section, the groove of both sides location-plate is colluded toward the back leg alignment pin, whole chair just fixedly has been shaped, and the groove on the adjusting location-plate and the position of alignment pin can make the chair back obtain different angles, when folding, take two location-plates, the seat support and the chair back are mated to equidirectional, can realize folding.On the chair back, fixing a base plate, on 2 guide rails are housed.On the centrage of base plate, be provided with symmetrical two massage wheels, the wheel spacing equates on two supports, two road wheels are arranged respectively under the support about massage wheels is installed in by axle with the human vertebra width, road wheel is contained in the guide-track groove, can walk along guide rail.On the massage wheel shaft, fixing a chain gusset piece, end with pin and gusset piece of chain is fixed, chain is by the minor sprocket of chair back upper end, return hinge wheel behind the chair back by chair back lower end, return the chain gusset piece, the other end fixedly formed a chain drive system with bearing pin with chain and chain gusset piece.Hinge wheel is contained on the output shaft of decelerator, decelerator and motor coupler.Motor is fixed on the motor fixed base plate that links with preceding chair lower limb.Upper and lower side at a side rails respectively has a spacing shape journey switch, when not working, massage wheels is in below the seat support, folding seat can be done a conventional chair and use, when energized, motor clockwise rotates, and drives chain by hinge wheel after slowing down by decelerator massage wheels is moved upward along guide rail, upwards massages cervical vertebra from the caudal vertebra of human body always.Massage wheels is touched the upper limit travel switch after arriving highest order, make the motor counter-rotating, massage wheels is walked downwards, after arriving the lower end, touch the lower limit travel switch, motor just changes, massage wheels is walking upwards, (being generally 15 minutes) massage wheels is under circuit control after reaching massage time of regulation and so forth, and (circuit theory diagrams are very simple to be omitted) automatically returns to original position, and massage finishes.

Owing to adopted said structure, collapsible massage armchair can effectively be massaged whole vertebra both sides, not the time spent collapsible, reduce and take up an area of the space, the simple and direct practicality of structure, cost is low, is easy to popularize.

Below in conjunction with accompanying drawing and example this utility model is further specified.

Fig. 1 is an example cross-section structural map that removes cloth cover and foam plastics of the present utility model.

Fig. 2 is an example front view that removes cloth cover and foam plastics of the present utility model.
