Description

The back type massage device

This utility model relates to a kind of back type massage device that uses what massage armchair back, and particularly a kind of massage machine that is used for massaging the user back specially belongs to what health-care hospital field.

The kind of masseur is a lot, as foot sole massager, head massager, back massager etc., and the mode of massage is nothing more than modes such as spine, roller rolling and extruding, in order to stimulate muscles and bones, muscle and the acupoint of user,, and promote that user is healthy with allaying tiredness, and back massager generally all adopts the rolling wheel massaging mode, in order to cooperate common people's back length, make on the roller usually, top offset, with the entire back of massage user.

The roller of existing back massager is last, during bottom offset, move not steady, also have some setbacks, as apply for [structure-improved of cushion rolling wheel massaging device] novel patent case No. 85203001, its drive mechanism is to utilize drive motor to drive belt on a chassis body, the belt drive is provided with on the horizontal seat of slip of roller, bottom offset, the problem that this patent exists is: complex structure, and it mainly is to utilize the framework and the body of rod that massage roller is set, it is to be driven by belt that the horizontal seat of roller slip is set simultaneously, have transmission slip and loose problem by the what belt, its displacement is more not steady, also have some setbacks.

For the upper and lower displacement that makes massage roller non-slip, steady, massage roller is pivoted on what one screw rod, and utilize motor to drive worm screw, worm gear, make the screw rod upper and lower displacement of worm gear relatively, though improved transmission efficiency, yet the weight that must be born whole message structure by the what screw rod moves together, and there is not suitable guiding structural again, therefore when message structure upper and lower when mobile, still can't effectively overcome the problem that its displacement is not steady and have some setbacks, even cause the damage of assembly, and shortened the service life of massage armchair.

With regard to aforementioned two kinds of different back massagers, all are the wobbler actions that utilize roller simultaneously, reach the effect of extruding massage, therefore its effect can't satisfy the demand of general user not as the effect of acupoint massage and kneading massage.

The purpose of this utility model particularly provides a kind of back type massage device with preferable massage effect at the back type massage device that what provides a kind of message structure to move steady and smooth.

The technical solution of the utility model is:

This back type massage device includes: a slide track seat, be bent with corresponding slide groove portion respectively in its both sides of the edge, slide track seat what hypomere is installed with the motor seat of a tool motor, motor drive shaft is provided with a worm screw, be pivoted with a screw rod that extends to the slide track seat apical margin on the motor seat, the screw rod hypomere is installed with a worm gear that is meshed with worm screw;

One bearing, these both sides, bearing back side are respectively equipped with a slide block, and the slide groove portion of two slide blocks and slide track seat both sides is sliding fit, and two slide blocks are provided with the pearl groove of series, be installed with the ball that a periphery protrudes from shoe surface in each pearl groove respectively, bearing is provided with some swivel nuts that cooperate with screw flight; On slide track seat, be provided with can upper and lower slippage bearing, and the what bearing is provided with some message structures, the slide groove portion of slide track seat is the dovetail groove shape, the slide block of bearing then is corresponding dovetail shape;

Slide track seat apical margin central authorities are provided with a motor seat that extends forward, are installed with an axle sleeve on the motor seat, and the corresponding slide track seat centre of the upper and lower two sheet whats of motor seat is respectively equipped with an axle sleeve, is pivoted for screw rod;

The upper and lower edge of skeleton frame central authorities are respectively equipped with upper and lower, and swivel nut then sets up separately on upper and lower of the what, is threaded engagement with screw rod;

Message structure is to be provided with a motor with driving gear in bearing, and the idle pulley that driving gear and both sides are pivoted on the what bearing is meshed, the idle pulley both sides are meshed with driven gear on being hubbed on bearing, and each driven gear is provided with the eccentric massage bar that protrudes bearing.

The utility model has the advantages that:

1, the mobile more steady and smooth of bearing 20: slide track seat 10 is provided with the slide groove portion 11 of dovetail groove shape, and be provided with the slide block 21 of corresponding slide groove portion 11 on the bearing 20 in addition, be provided with the ball 23 of series in the slide block 21, therefore whole bearing 20 is when sliding, smooth and easy and steady, the abrasion that can slow down member have prolonged service life.

2, has preferable massage effect: because massage bar 35 is eccentric shape, when massage bar 35 is rotated, produce relative closing and isolating gyration, form a kind of similar massage effect of rubbing, pinching, the existing back type massage device of certain excellent what, the comfort of promoting user.
