Description

Technical Field

[0001] The utility model relates to the technical field of lifting seats, in particular to a rotating mechanism and a seat. Background Art

[0002] Many existing seats usually set up a rotating mechanism for support. The rotating mechanism mainly consists of a support structure and universal wheels at the bottom, so as to realize that the seat can walk and rotate on the ground. The rotating mechanism can support the whole seat and the legs of the person. The part for the legs of the person is called the footrest part. However, for different people, the support of the footrest part on the rotating mechanism for the user is different, resulting in discomfort in the legs of some people.

[0003] The main reason for the above problems is that for children or adults, their leg lengths are different, so the contact between them and the footrest part is different. Moreover, the setting position of the footrest part at the lifting seat is fixed. For example, for children, their legs are relatively short. When they sit on the seat, the distance between their feet and the footrest part is large, resulting in the legs of children being in a suspended state. After a long time, it will cause soreness in the legs, making their comfort during the use of the seat poor. In view of the above problems, we propose a rotating mechanism and a seat.
