Folding chair with speed reducer

Abstract

The invention relates to a folding chair with a speed reducer. The folding chair comprises a chair support, a backrest and a folding seat, the folding seat is connected to the chair support through a seat rotating shaft, can rotate along the seat rotating shaft and can be vertically folded, one end of the seat rotating shaft is connected with the speed reducer, and the other end of the seat rotating shaft is connected with a return spring. The chair is provided with the speed reducer in order to make the folding motion be stably generated and avoid noise pollution caused by sudden folding due to elastic force, and the folding motion which is carried out stably and slowly does not generate bump to the seat, so the seat is not damaged, and the service life of the seat is greatly prolonged; the stable and slow implementation of the folding motion avoids the risk of bumping of the chair seat to people; and the speed reducer is specially used for the folding chair, so the speed reducer is convenient for being used together with the folding chair, and the folding chair is fast and convenient to install and is convenient to replace and maintain.

Description

technical field [0001] The invention relates to a folding chair, in particular to a folding chair with a speed reducer in a public place. Background technique [0002] Chairs are widely used in public places such as stadiums, theaters, and entertainment venues. Some of the seats in these public places are arranged in parallel in rows, such as cinemas, conference rooms, etc., and some are placed in corridors, such as hospital corridors. In order to make it easier for customers to come in and out between rows or in corridor passages and clean and sanitation, chairs are usually equipped with a structure that makes the seats foldable, so that when the chairs are not in use, the rows of chairs expand the space of the passage due to folding. When the chair is in use, the weight of the user keeps the seat of the chair in a lower use position; conversely, when the chair is not in use, the seat panel can be folded vertically to the lower side position against the back of the chair. ...
