Description
Technical Field
The utility model relates to an improvement of a chair back with a machine core capable of adjusting the angle in a rotating way, in particular to an assembly of the machine core through a shaft sleeve and a rotating shaft, which is more convenient to assemble; the core forms a seesaw structure through the movable structure of the shaft sleeve and the rotating shaft; when in massage, the machine core can swing back and forth along with the curve of the human body, the massage is more comfortable, and the chair back with the machine core capable of completely massaging in place can rotate to adjust the angle.
Background
At present, simple massage chairs are all provided with a massage machine core which is directly and fixedly arranged at the waist position of a person sitting on the chair, and massage is realized through the rotation of rollers on the massage machine core. However, because the waist curves of each person are different, the fixed movement can cause the massage to be more rigid, and the waist curves can cause the massage to be not in place.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the technical problem that the machine core is assembled through the shaft sleeve and the rotating shaft, and the assembly is more convenient; the core forms a seesaw structure through the movable structure of the shaft sleeve and the rotating shaft; when in massage, the machine core can swing back and forth along with the curve of the human body, the massage is more comfortable, and the chair back with the machine core capable of completely massaging in place can rotate to adjust the angle.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a chair back with a machine core capable of adjusting angles in a rotating mode comprises: a chair back frame and a movement; two sides of the machine core are respectively provided with a fixing strip; the middle parts of the two fixing strips are respectively provided with a shaft sleeve; each shaft sleeve is internally provided with a rotating shaft; the two rotating shafts are respectively and fixedly arranged on the corresponding chair back frame; a fixed rod is arranged on each of the two sides in the chair back frame; the two rotating shafts are respectively and fixedly arranged on the corresponding fixing rods.
Preferably, the fixing strip is a metal plate fixing strip.
Preferably, the fixing strip is L-shaped; the openings of the two fixing strips are opposite, and the movement is arranged between the two fixing strips with the opposite openings.
Preferably, a shaft sleeve fixing piece is arranged between each shaft sleeve and the corresponding fixing strip; the shaft sleeve fixing piece is fixed on the fixing strip.
Preferably, the chair back frame is provided with a movement protecting frame at the rear end of the movement.
The utility model has the advantages that: the chair back with the machine core capable of adjusting the angle in the rotating way has the advantages that the machine core is assembled through the shaft sleeve and the rotating shaft, so that the assembly is more convenient; the core forms a seesaw structure through the movable structure of the shaft sleeve and the rotating shaft; when in massage, the machine core can swing back and forth along with the curve of the human body, so that the massage is more comfortable, and the massage can be completely performed in place.
