Swing mechanism capable of adjusting swing amplitude, swing chair frame and swing chair

Abstract

The invention relates to the technical field of chair swinging, in particular to a swinging mechanism, a swinging chair frame provided with the swinging mechanism and a swinging chair. The swing mechanism comprises a driving assembly, an eccentric part connected with an output shaft of the driving assembly and a shaft rod assembly connected with the eccentric part; the eccentric part does synchronous circumferential rotation along with an output shaft of the driving assembly, and one end of the shaft rod assembly is hinged to the eccentric part and does synchronous circumferential rotation along with the eccentric part; and in the rotating process, the shaft rod assembly swings forwards or backwards in a reciprocating mode. The automatic swinging effect can be achieved through part matching of the swinging mechanism, and the swinging mechanism can be suitable for various chair frames capable of swinging.

Description

technical field [0001] The invention relates to the technical field of chair swing, in particular to a swing mechanism capable of adjusting the swing range, a swing chair frame, and a swing chair. Background technique [0002] Office swivel chairs are generally used by people in office places. The common office swivel chairs are pneumatic lift office swivel chairs with springs as bearings. They only have lifting and rotating functions, and there are also incidents of air pressure injury, which is not safe. The crowd in the office is mostly mental workers, with heavy work, high pressure, and easy fatigue. In order to alleviate fatigue, relax nerves, and reduce stress, various seats or beds have also appeared in the prior art, but these are generally massage chairs and massage beds, which are expensive, and have a complicated volume and structure. The space itself is limited, and adding a massage bed or massage chair makes the limited space even smaller. [0003] For example...

AI Technical Summary

Problems solved by technology

Compared with the traditional office swivel chair, without affecting the appearance and structural strength of the office swivel chair, the rocking chair frame replaces the traditional office swivel chair bearing and chassis, reduces springs, bearings, air valves and other components, saves raw materials, reduces process, the structural design is more compact, practical, simple, and safe; and the patent mainly causes the chair frame to swing back and forth through the center of gravity of the human body, and at the same time highlights several problems: 1. The swing range is unpredictable, or it is limited. It depends on the rotation angle of the swing frame relative to the seat assembly. Once the swing range is unpredictable or limited, it will also be limited to the applicable crowd. Therefore, the limitation is relatively large; 2. The swing power source of the chair still comes from The swing of the chair can only be achieved by people swinging, which does not have the effect of relaxing and relieving fatigue, and the swing process still requires people to participate
