Description
Technical Field
The invention relates to the technical field of furniture, in particular to a massage chair.
Background
The massage chair is an essential article in modern fast-paced life, can bring comfort and relaxation to users when the users are tired, and is deeply popular in the market; however, in order to ensure the stability of the massage chair in the market, the massage chair has a single function and no function of leaning and swinging, and when a user sits on the massage chair, the user can only keep one posture, so that the massage chair is very ancient, poor user experience is brought in practice, and the use range and the use place of the massage chair are greatly limited; in addition, even though the massage chair on the market has a tilting and swinging function, an electric swinging device is basically adopted, but the electric swinging device has a complicated structure, is difficult to maintain, has a large volume and high cost, and has a low popularization rate.
Therefore, chinese patent publication No. CN205729740U discloses a massage chair, which comprises a base, and a seat body movably disposed on the base; the chair seat body is connected to the base through a swinging device which is a non-electric swinging device; the swing device comprises a lower base, an upper base, an elastic assembly and a first limiting part, wherein the elastic assembly and the first limiting part are used for adjusting the hinge angle between the upper base and the lower base, and the elastic assembly and the first limiting part are respectively arranged on two sides of a rotating shaft. Compared with the prior art, the massage chair provided by the utility model has the advantages that the non-electric rocking device is arranged below the chair seat body, so that the tilting and rocking function of the chair body is realized, the comfort, the flexibility and the interestingness of the massage chair are improved, the defect of the single function of the traditional massage chair is overcome, and the adopted non-electric rocking device has simple accessories, so that the maintenance is convenient, the cost is reduced, and the operation is convenient for users, therefore, the massage chair can be used for household and office facing more consumer groups, and has better market prospect; however, the structural configuration of the device requires a high space height, a large overall size, a complex structure and a correspondingly high production cost.
Chinese patent publication No. CN204519951U discloses a swivel chair tray, and the present invention relates to a swivel chair tray, and more particularly to a screw-adjusting swivel chair tray for changing the angle of a torsion spring. It mainly is that the swivel chair tray that solves prior art existence can't adjust the angle of torsional spring, therefore the regulation dynamics of seat can't change, operates the technical problem of comparatively inconvenient etc.. The utility model discloses a bottom plate, the bottom plate on have the middle seat through the hub connection, the middle seat is fixed with the conical tube through the taper pipe soldering lug, the epaxial cross-under has the torsional spring, the torsional spring is connected with the adjustment mechanism of adjustable torsional spring angle through the torsional spring fixed block adjustment mechanism includes spiral regulation piece and lower spiral regulation piece, but technical personnel in this field discover in the use, it has following problem:
1) the height of the torsion spring fixing block is adjusted through the matching of the upper spiral adjusting block and the lower spiral adjusting block, so that the angle of the torsion spring is adjusted, when the height of the torsion spring fixing block is higher, the pressure of the torsion spring on the torsion spring fixing block is higher, however, the contact surface between the upper spiral adjusting block and the lower spiral adjusting block is smaller, and the adjustment stability is not facilitated;
2) the adjusting range of the lower spiral adjusting block is only 360 degrees, if the adjusting range exceeds 360 degrees, the upper spiral adjusting block and the torsion spring adjusting block can suddenly drop because of losing supporting force, and the dislocation between the upper spiral adjusting block and the torsion spring adjusting block can be caused to lose an adjusting function, the adjustment of the lower spiral adjusting block is manually controlled through a handle, and therefore the condition exceeding 360 degrees can be generated in time, and the stability of adjustment is not facilitated.
