Abstract

The invention relates to a seat cushion folding and foot placing plate automatic-telescoping device of a dental chair, and belongs to the field of dental medical treatment instrument manufacturing technique. The seat cushion folding and foot placing plate automatic-telescoping device of the dental chair is characterized in that foldable devices are arranged among the connection of a rear seat cushion support and a connecting portion between a foot placing plate support and the back connection piece, an automatic-telescoping device is disposed under a front seat cushion, and the foot placing plate is fixedly disposed on the automatic-telescoping device. The seat cushion folding and foot placing plate automatic-telescoping device of a dental chair is simple in structure, small in size, and stable and reliable in operation, and with a torsion spring acting as an elastic force application element, the device has more security, the problem that a human body is squeezed or equipment is damaged can be prevented. With the back luffing and seat cushion folding movement of the dental chair, the back of the dental chair is used for driving the push-and-pull movement of a motor during the luffing, the synchronous linkage of the foot placing plate in the front of the seat cushion is produced by torsion of the torsion spring and transmission of a stay wire, thereby automatic telescoping of the foot placing plate is realized.

Description

1. Technical field [0001] The invention relates to a foldable and automatically telescopic dental treatment chair, in particular to a dental chair seat cushion folding and footrest automatic telescopic device, which belongs to the technical field of dental medical equipment manufacturing. 2.
