Abstract

The utility model relates to a massage chair structure, which comprises a chair face and a chair back, wherein, a massage mechanism and a guide screw transmission mechanism are arranged in the back of the chair back. A sliding block is fixed on the massage mechanism to form a screw matching with the guide screw in the guide screw transmission mechanism. Sliding members are hinged on two ends of the massage mechanism, which can slide along a guide apparatus on two sides of the chair back up and down. Two sides of the chair back are of curve shapes matching with the back of human body. The sliding block fixed with the massage mechanism matches with the other guide apparatus. Because the guide apparatuses arranged on two sides of the chair back have a curve shape matching with the back of human body, a massage wheel on the massage mechanism can contact with the back of human body in same force when the massage mechanism moves along the guide apparatuses arranged on two sides of the chair back up and down, thereby eliminating uneven stress on the back of human body due to straight line movement of the massage mechanism with excellent using effect.

Description

A kind of massage armchair structure

Technical field:

This utility model relates to the casual health product technical field, especially a kind of massage wheels can the fit curve shape of human body back and the massage armchair structure that moves up and down.

Background technology:

Current, with the quickening pace of modern life, people except hope can relax nervous nerve, wish that also the health of oneself can relax as far as possible after the work of anxiety, so that there is more abundant energy to meet going up and challenge in life from work of next round.The various massage armchairs of Chu Xianing are just in order to satisfy the needs of people's this respect in the market, these massage armchairs are not only handsome in appearance, and above user sits on the time, the massage mechanism of chair back back can be under the drive of lead-screw drive mechanism move up and down along chair back both sides, makes the massage wheels that protrudes from chair back front end face and withstand on human body back form the effect of similar massage to the back of human body.But, existing massage armchair its both sides are types linearly, that is to say, massage mechanism with and on massage wheels can only move up and down along rectilinear direction, and well-knownly be: the back of human body has certain curve shape, and the massage wheels that is fitted in human body back is as moving up and down by rectilinear form, then must cause some places of human body back stressed excessive, make user feel under the weather, the then stressed deficiency in other places, the difficult people's will to the greatest extent of massage effect.

Summary of the invention:

The purpose of this utility model provides a kind of ergonomical massage armchair structure with regard to being at the deficiencies in the prior art part.

For achieving the above object, this utility model comprises: the seat and the chair back, wherein, the back of the chair back is provided with massage mechanism and lead-screw drive mechanism, be fixed with on the massage mechanism with lead-screw drive mechanism in leading screw constitute the slide block of threaded engagement relation, the two ends of massage mechanism are hinged with sliding part, sliding part can slide up and down along the guider of chair back both sides, the both sides of the described chair back are the curve shape that matches with human body back, then cooperate with another guider with the slide block that massage mechanism is connected, slide block can be done along this guider and move forward and backward.

The sliding part that is articulated in the massage mechanism two ends is a roller, and the guider of the chair back both sides that cooperate with roller is then for directly being opened in the chute of chair back both sides.

Described guider is made of two symmetric guide pads in position, and guide pad offers the gathering sill that cooperates with slide block respectively on the relative side end face, and slide block can move forward and backward in gathering sill.

The beneficial effects of the utility model are: because the guider of chair back both sides has the curve shape that matches with human body back, like this, when the guider of the suitable chair back both sides of massage mechanism moves up and down, massage wheels on the massage mechanism also just can contact with the back of human body with identical dynamics all the time, thereby the phenomenon of the human body back unbalance stress that the elimination massage mechanism causes because of straight line moves, result of use is very good.In addition, the existence of another guider that cooperates with slide block, then can guarantee massage mechanism can fair curve the guider of chair back both sides of shape do and move up and down.

Description of drawings:

Below in conjunction with accompanying drawing this utility model is described further:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is the structural representation of massage mechanism and lead-screw drive mechanism

Accompanying drawing 3 is the local enlarged diagram of accompanying drawing 2

The specific embodiment:

The following stated only is a specific embodiment of the utility model, does not therefore limit protection domain of the present utility model.

See shown in the accompanying drawing 1～3, massage armchair of the present utility model mainly is made up of the seat 10 and the chair back 20, wherein: the back of the chair back 20 is provided with massage mechanism 30 and lead-screw drive mechanism 40, be fixed with on the massage mechanism 30 with lead-screw drive mechanism 40 in leading screw 41 constitute the slide block 31 of threaded engagement relation, after leading screw 41 rotated, slide block 31 can drive whole massage mechanism 30 and move up and down.

The two ends of massage mechanism 30 are hinged with as the roller of sliding part 32 (certainly, except roller, sliding part 32 also can be a slide block), the both sides of the chair back 20 then offer the chute 21 (guider) that cooperates with roller 32, the chute 21 of the chair back 20 both sides has the curve shape that matches with human body back, and roller 32 is embedded and also can sliding up and down in chute 21 within the chute 21; Certainly, this chute 21 also can change curvilinear lead into, and sliding part 32 then can be the slide block that is enclosed within on the lead.

Also be fixed with on the massage mechanism 30 by two symmetric guide pads 51 in position and 52 another guiders 50 that constitute (described guider 40 can be more than), guide pad 51 offers the

gathering sill

511 and 521 that cooperates with slide block 31 respectively on the side end face relative with 52, and slide block 31 can move forward and backward in gathering sill 511 and 521.It should be noted: also can offer chute in the both sides of slide block 31, described

guide pad

51 and 52 then is embedded in chute (also can need only a guide pad), equally also can make slide block 31 reach the purpose that moves forward and backward.

During use, after leading screw 41 rotates, the slide block 31 that constitutes threaded engagement relation with it can drive whole slide mechanism 30 and move up and down along the curve-like chute 21 of the chair back 20 both sides, and when slide mechanism 30 when curved chute 21 moves up and down, massage wheels 33 on it can fit with identical dynamics and human body back all the time, thereby reaches ideal massage effect.
