Abstract

The utility model provides a curved sliding rail transmission controller for a massage chair, the structure of which is that a curved sliding rail of a massage mechanism is formed according to the curve of human back, a group of movable sliding seats and a sliding shaft device which are connected with the back face of the massage mechanism and combined with a driving bolt are utilized, the sliding shaft is limited in a sliding groove of the sliding seat and is combined with the driving bolt, and the sliding shaft moves upwards and downwards following the rotation of the driving bolt. When the sliding seat and the massage mechanism are driven to move upwards and downwards in the sliding rail, and the curved position of the sliding rail is passed by, the sliding seat can shift forwards or backwards correspondingly to the sliding shaft because of the bending degree of the sliding rail, so the massage mechanism arranged on the sliding seat can run favorably on the curved sliding rail so as to obtain comfortable massage effect.

Description

The curved slide rail transmission control device of massage armchair

This utility model relates to a kind of parts of electrically driven (operated) massage armchair, particularly a kind of massage armchair.

The major function of massage armchair is that human body back muscle is implemented massage, uncomfortable with allaying tiredness or local muscle, general structure as shown in Figure 1, establish slide rail 11 in massage chair back pedestal both sides, 12, between two slide rails, establish one group of wheel massage mechanism 10, the pulley that massage mechanism 10 is installed with both sides (being positioned at the inboard figure of slide rail does not show) is at slide rail 11, move up and down on 12, the motion of massage mechanism 10 is to drive with the banded guide bracket 13 in its back side with by the screw rod 15 of motor 14 transmissions, when motor 14 is done rotating, guide bracket 13 drives massage mechanism 10 at two slide rails 11, move back and forth up and down on 12, its pulley carries out that the human body back massage is had suitable effect to loosening human body back muscle.

But said structure, its two

slide rail

11,12 is vertical, thereby moving up and down also of massage mechanism 10 advanced on straight line path, and the curved state of human body back, in the time of on lying at the chair back, also can't be flattened on the chair back, straight line moves the massage mechanism of lifting, massage produces the strength that weight differs to back bodice curve, be that some position is because of the algesiogenic sensation of excessive weight, some position is not then because of being affixed on the chair back massage force quantity not sufficient that seems, repeatedly in the lifting massage, promptly brings the back uncomfortable massage effect at this.

The purpose of this utility model is to provide a kind of massage armchair curved slide rail transmission control device, and it can produce the comfortable massage strength identical to the human body back curved surface, and can make the lifting action of massage mechanism more smooth and easy.

Utility model is achieved in that the characteristics of the curved slide rail transmission control device of massage armchair are, it is linked to the slide in the guide bracket outside, inner integrally formed central chute, left and right sides chute reach chute up and down, insert a cushion block in the gliding groove, central authorities' chute, chute and cushion block central authorities form corresponding up and down notch up and down, insert a slide-bar and with the capping sealing, the sheathed bearing in slide-bar two ends splits in the chute of the left and right sides in slide central authorities chute, tool one runs through screw on the slide-bar, and screw is in conjunction with drive screw.The mat slide-bar rotates with screw rod and in the lifting, slide drive guide bracket and massage mechanism is slided on curved slide rail.

When this utility model is passed through curved slide rail in the massage mechanism lifting, can with respect to interior establish slide-bar do before and after displacement, make massage mechanism with displacement before and after it smoothly by the slide rail of different curvatures, produce the comfortable massage strength identical to the human body back curved surface; Be installed in the slide-bar on the inner chute of slide, the sheathed live bearing in its two ends makes slide carry out relative moving forward and backward, and obtains best activeness, and then makes the lifting action of massage mechanism more smooth and easy.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is that dress massage mechanism axle is surveyed sketch map in traditional massage armchair.

Fig. 2 is the curved slide rail transmission control device of a this utility model massage armchair structural representation.

Fig. 3 is slide and a slide-bar combination axonometric exploded view among Fig. 2.

Fig. 4 is that Fig. 2 structure is implemented view.

With reference to Fig. 2,3, this utility model device is at the massage mechanism 20 of 21,22 of two curved slide rails, be to drive in conjunction with the screw rod 25 that is subjected to motor 24 transmissions with the banded slide 30 in its back side guide bracket 23 outsides, with slide 30 in screw rod 25 transmissions, make massage mechanism 20 carry out massage effect in 21,22 liftings up and down reciprocatingly of two curved slide rails.

Be attached at the slide 30 in guide bracket 23 outsides, its inner integrally formed central chute 31, left and right sides chute 32,33

reach chute

34,35 up and down, insert a cushion block 36 in the gliding groove 35, at central chute 31,

chute

34,35 and cushion block 36 central authorities respectively offer notch 37 corresponding about in the of up and down; Insert a slide-bar 40 and with capping 50 sealing in slide 30, slide-bar 40 is each sheathed-bearing 41,42 and be positioned at left and right sides chute 32,33 at two ends, can be very smooth and easy when slide 30 relative slide-bars 40 are moved forward and backward; Slide rail 40 bodies are positioned at central chute 31, and running through a screw 43 on it can be in conjunction with screw rod 25, and make 37 in the corresponding notch of screw rod 25 by each chute.

With reference to Fig. 4, when screw rod 25 rotates, slide-bar 40 can done on the screw rod 25 or move down because of the combination of its screw 43, it moves through slide 30, guide bracket 23 and drive the slide down wheels 26 of massage mechanism 20 with its both sides, 27 at curved slide rail 21, go up or move down for 22, when pulley 26 or 27 one of them slide rail 21 of passing through, 22 crooked position and need make massage mechanism 20 reach or retreat with the time by slide rail, guide bracket 23 must or retreat with massage mechanism 20 reaches, drive the relative displacement that slide 30 produces the slide-bar 40 that is subject to screw rod 25 by moving of guide bracket 23, be that slide-bar 40 keeps resting state, and with its

bearing

41,42 make slide 30 produce relatively moving of moving forward or retreat, and make the pulley 26 of massage mechanism 20 by this, 27 can be smoothly at curved slide rail 21,22 slide up and down.
