Abstract
The utility model relates to a driving wheel height adjusting device for the electric refit of a hand-operated wheelchair, which comprises an independent driving wheel, a front fork, a shaft sleeve and a bearing of the front fork, a vibration damper, a crossbeam, a lower connection board of the front fork and a hollow pipe shaft arranged thereon, an upper connection board of the front fork and a hollow pipe shaft arranged thereon, a height regulation bolt, a height regulation nut and a handle locking device.The upper portion of the hollow pipe shaft of the upper connection board of the front fork is equipped with a notch.The hollow pipe of the lower connection board of the front fork is inserted in the hollow pipe shaft of the upper connection board and extends out of the hollow pipe shaft of the upper connection board.The hollow pipe shaft of the upper connection board of the front fork is inserted in the shaft sleeve of the front fork and is positioned by the bearing of the front fork.The handle locking device is arranged at the notch arranged at the upper portion of the hollow pipe shaft of the upper connection board of the front fork.The height regulation bolt is positioned by a nut after passing through the holes of the upper and lower connection boards of the front fork.The height adjusting device is simple in structure and reliable in operation, wherein the conversion of the hand-operated mode and the electrically-driven mode of a wheelchair is achieved only by a user itself without external help.The height adjusting device is suitable for further application.
Description
Technical field:
This utility model relates to a kind of manual pulley Wheel-chair, more specifically to a kind of driving wheel dipping control that is used for the electronic repacking of manual wheelchair.
Background technology:
In the prior art, the most unpowered device of wheel Wheel-chair needs to promote with the hand push circle of hands rotation wheelchair or by the nurse personnel by user.For improving individuals with disabilities's quality of life, scientific and technical personnel improve manual wheelchair, on the manual pulley Wheel-chair, installed powered wheel additional, the weak point that present this repacking powered wheel exists is: when power-supply battery exhausts or other faults, because powered wheel can't break away from ground, and there is magnetic resistance in powered wheel inside and causes the caregiver to promote wheelchair and becomes very painstaking, saying nothing of the individuals with disabilities who is sitting in the wheel Wheel-chair and rotated the hand push circle with hands, is that a urgency is treated improved problem.
The utility model content:
The purpose of this utility model is the driving wheel dipping control that is used for the electronic repacking of manual wheelchair that the hand push circle still can conveniently be provided when providing a kind of power-supply battery to exhaust at the prior art weak point.
The purpose of this utility model is to realize by following measure: a kind of driving wheel dipping control that is used for the electronic repacking of manual wheelchair, include drive wheel, front fork, front fork axle sleeve and bearing, vibroshock, crossbeam, it is characterized in that also having front fork lower connecting plate, front fork lower connecting plate hollow tubular shaft, front fork upper junction plate, front fork upper junction plate hollow tubular shaft, height to regulate screw bolt and nut, handle locking device; Described front fork upper junction plate hollow tubular shaft lower end is fixed on the front fork upper junction plate, front fork upper junction plate hollow tubular shaft upper end is provided with otch, described front fork lower connecting plate hollow tubular shaft lower end is fixed on the front fork lower connecting plate, front fork lower connecting plate hollow pipe pipe shaft inserts in the front fork upper junction plate hollow tubular shaft and the outer upper junction plate hollow tubular shaft of stretching out, front fork upper junction plate hollow tubular shaft is inserted in the front fork axle sleeve and by front fork axle sleeve bearing and is located, the handle locking device is installed in otch place, front fork upper junction plate hollow tubular shaft upper end, described height is regulated bolt and is passed on the front fork, locate by nut behind the hole of lower connecting plate, described drive wheel is installed in the front fork, vibroshock is installed on the front fork, between the lower connecting plate, the front fork axle sleeve is fixed on the crossbeam.
Described handle locking device is embraced ring, nut, screw rod, eccentric handle by opening and is formed; Described screw rod one end inserts in the prong of eccentric handle and is hinged and connected to together by hinge pin, and screw rod other end screw head passes the hole that opening embraces on the ring galianconism and is connected with nut.
Compared with prior art, owing to adopted the driving wheel dipping control that is used for the electronic repacking of manual wheelchair of the present utility model, when the power supply of electric driver exhausts or other faults, the drive wheel location can be heightened, make it break away from ground, the resistance when reducing with the hand propelled wheelchair; When need are electronic when travelling, the drive wheel location can be turned down, make the manual wheelchair front-wheel take off ground, ground.This utility model is simple in structure, and reliable operation is convenient to the conversion of push-chairs mode and electric type of drive, and user need not the conversion that other people help to finish voluntarily the method for operation, can promote the use of.
Description of drawings:
Fig. 1 is the structural representation of this utility model embodiment.
