Toothed wheel and wheelchair

Abstract

Disclosed is a toothed wheel and a wheelchair. A tooth protecting disk of the toothed wheel is connected with a connecting shaft; the connecting shaft is connected with a power shaft; a plurality of wheel tooth seats which are equally distributed are disposed around the axis of the connecting shaft in a radial direction of the outer wall circumference of the connecting shaft and the surface of thetooth protecting disk; wheel teeth are accommodated on each of the wheel tooth seats contains; tooth roots and tooth crowns are sleeved and are slidably telescopic relative to each other; and the wheel teeth are limited and locked by a wheel tooth self-locking and limiting device which is additionally disposed. The toothed wheel is artful in design and simple in structure, and the wheel tooth self-locking and limiting device which is additionally disposed controls and locks the telescoping of the wheel teeth. If the toothed wheel meets a complex road condition, the wheel teeth are changed with a contact surface, so that the holding power of the contact surface may be increased, the climbing reliability of the wheel is improved, and the climbing capability is enhanced. For the wheelchair,a seat is connected with a support frame shaped like a Chinese character "ge", the support frame is connected with a main wheel and a guide wheel of the toothed wheel, and the due to the rapid foldingand unfolding of the support frame shaped like the Chinese character "ge", the wheelchair is enabled to be rapidly switched to adapt to the complex road condition, and thus, the rapid and safe traffic capacity of the wheelchair is improved.

Description

technical field [0001] The invention relates to a wheel, in particular to a deformable wheel and a wheelchair. Background technique [0002] At present, it is not uncommon to use wheels in ladder environments in the known published patent documents, but the structure is complicated, the maintenance is cumbersome and difficult, the cost is high, and the operation is inconvenient. The mobility of wheelchairs in complex road conditions is not good, and the operation is not easy. Contents of the invention [0003] The purpose of the present invention is to provide a deformable wheel and a wheelchair. [0004] The present invention takes following a kind of deformation wheel technical scheme for reaching this purpose: [0005] A toothed wheel, including a wheel for moving and walking, which consists of: a tooth seat (or bracket), a tooth [a tooth crown or a tooth composed of a tooth crown and a tooth root], a tooth guard, a connecting shaft, A gear tooth self-locking limit d...
