Abstract
The invention discloses a chair capable of rotating. The chair comprises a chair back, a chair seat, a fixed bottom plate, and a rotating bottom plate; the fixed bottom plate and the rotating bottom plate are connected through a concave-convex structure; a bearing and a jacking mechanism are arranged between the fixed bottom plate and the rotating bottom plate, the bearing and the jacking mechanism are used to rotate the chair; and the jacking mechanism is composed of a pedal, a short connecting rod, and a long connecting rod. A jacking mechanism is adopted so as to rotate the chair, thus the rotating function of the chair is achieved so the chair can be used in a certain occasion that need a rotatable chair; and moreover the operation of the chair can save time and labor. The chair provided by the invention has the advantages of simple structure and convenient installation and maintenance, reduces the workload of workers, and saves the cost.
Description
Technical field
