Mechanical support structure for chair

Abstract

The invention discloses a mechanical support structure for a chair. The mechanical support structure includes a hollow shell and a seat, the interior of the hollow shell is of a hollow structure, a movable space is formed, a group of cylindrical blocks with an iron core inside is fixed at the top, in the movable space, of the hollow shell, a group of coils is twined on the surface of the iron core, and a wire through hole structure is arranged on the position, where the coils are located, of the side face of the hollow shell. According to the mechanical support structure for the chair, electromagnetic action is adopted to serve as a main driving medium for adjusting the mechanical support structure, and the controllability is relatively high; besides, the interaction between electricity and magnetism is adopted, a support force can be effectively provided, and buffer action is provided at the same time, so that buffing-type support is achieved; because the interaction force between the electricity and the magnetism is an electric-field force, the leakage phenomenon cannot occur, so that the service life is relatively long; besides, the mechanical support structure can prevent the seat from rotating freely and improve the fitness of the mechanical support structure for people.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a mechanical support structure for a chair. Background technique [0002] my country Patent No. 201420278161.2 discloses a boss chair with fitness function, including a base, a seat is placed on the base, armrests are placed on the left and right sides of the seat, the rear end of the seat is connected to the backrest, and a fitness tensioner is arranged at the bottom of the seat. The fitness tensioner includes a tension spring. The two ends of the tension spring are respectively connected to the spring support on both sides of the rear of the seat and connected to the hinge of the seat. The hinge shaft at the upper end of the spring support is fixedly connected with a vertical shaft, and one end of the tension handle is bent The sleeve is rotatably matched with the vertical shaft; or the side of the spring support hinged to the seat is hinged to the upwardly bent rotating sh...

AI Technical Summary

Problems solved by technology

The fitness tensioner includes a tension spring. The two ends of the tension spring are respectively connected to the spring support on both sides of the rear of the seat and connected to the hinge of the seat. The hinge shaft at the upper end of the spring support is fixedly connected with a vertical shaft, and one end of the tension handle is bent The sleeve is rotatably matched with the vertical shaft; or the side of the spring support hinged to the seat is hinged to the upwardly bent rotating shaft at one end of the pull handle, and the pull handle can drive the spring support to swing through the middle drive to make the pull It is obvious that the adjustment between the various components in the above device is adjusted by hydraulic components. In actual use, due to long-term use, it is inevitable that there will be liquid leakage, and its service life is low.
