Abstract
The utility model discloses a driving gear of a wheel chair. The utility model is characterized in that a left and a right two ends of a drive shaft are respectively provided with a reciprocating driving pawl sheet, cone gears are respectively sheathed on the driving pawl sheet, driven cone gears are engaged with the cone gears, and a back wheel of the wheel chair is driven to run; the reciprocating movement is done by shaking a handgrip to cause the wheel chair to forward run constantly. The utility model has the advantages of simple and compact structure, low cost, comfortable use and ride, and good safety performance; the utility model is an ideal tool for disabled people.
Description
Technical field: this utility model relates to a kind of Wheel-chair driving device of taking turns.
Background technology: manual pulley Wheel-chair driving device, its driving device structure generally adopts crank rocker to drive or gear drive drives, when adopting crank rocker to drive operation, be prone to the dead point, and adopting the gear transmission structure cost of manufacture higher relatively, structure is complicated, promptly is this as China Patent No. zL99254588.9 " single handle drives the wheel Wheel-chair of driving ", but its structure is complicated, and the production cost height is not easy to promote the use of.
The utility model content: this utility model will provide a kind of structure very simple, easy to operate exactly, the wheel Wheel-chair driving device that manufacturing cost is low.
The technical solution of the utility model is to realize like this: it comprises handle 1, and the conical gear 2,3 of ratchet in being provided with is past to driving click sheet 4, multiple to driving click sheet 5, driving shaft 6, driven shaft 8, driven bevel gear 7, conical gear 9,10, rear wheel 11 etc., handle 1 is connected with driving shaft 6, and driven shaft 8 one ends connect driven circular cone 7 other ends and connect conical gear 9, driven bevel gear 7 is meshed with conical gear 2,3 simultaneously, and conical gear 9 is meshed with conical gear 10; Be respectively equipped with at the two ends of driving shaft 6 toward to driving click sheet 4, multiple to driving click sheet 5, conical gear 2,3 is set with in toward to driving click sheet 4, and is multiple on driving click sheet 5, and is meshed with interior ratchet on its inwall.
It is simple in structure that this utility model adopts said structure that it is had, and manufacturing cost is low, and is easy for operation, and driving safety is comfortable, good stability.
Description of drawings: Fig. 1 is this utility model structural representation.
Among the figure: 1, handle, 2,3, the conical gear of ratchet in the band, 4, toward to the driving click sheet, 5, multiple, 6, driving shaft, 7, driven bevel gear, 8, driven shaft, 9,10, conical gear, 11, rear wheel to the driving click sheet.
The specific embodiment: as shown in Figure 1, this utility model handle 1 is fixedly connected on the middle part of driving shaft 6, be respectively equipped with past to driving click sheet 4 at the two ends of driving shaft 6, multiple to driving click sheet 5, the conical gear 2 of ratchet in being provided with, 3, be set in toward multiple on driving click sheet 5 to driving click sheet 4, and with its on the engagement of interior ratchet coupling, the conical gear 2 of ratchet in the band, 3 are meshed with driven bevel gear 7 simultaneously, driven shaft 8 one ends connect conical gear 7, the other end connects conical gear 9, and conical gear 9 is meshed with conical gear 10, and rear wheel 11 is connected with conical gear 10 by axle.
Its transmission process is as follows: shake handle 1 and do past to motion, driving driving shaft 6 does past to motion, be contained in driving shaft 6 one ends toward being meshed with interior ratchet on the suit conical gear 2 thereon to driving click sheet 4, and it is past to running to drive conical gear 2 works, this recurrence of disease at the same time next year is not worked to driving click sheet 5, drive driven bevel gear 7 runnings toward active conical gear 2 to running, the conical gear 9 of driven shaft 8 other ends also rotates, driving the conical gear 10 be contained on 11 of the rear wheels simultaneously does toward to running, rear wheel 11 is also done to take turns the i.e. operation forward of Wheel-chair toward to running.
When handle 1 write in reply to running promptly backward running drive driving shaft 6 and write in reply to motion, be contained in writing in reply to running to driving click sheet 5 promotion suits conical gear 3 thereon again on the driving shaft 6, this moment is toward not working to driving click sheet 4, multiple conical gear 3 to running drives the original direction of motion running of driven bevel gear 7 same maintenances, the conical gear 9 of the other end on the driven shaft 8 still drives conical gear 10 on 11 of the rear wheels and does toward to running, rear wheel 11 is also done past to running, it is reciprocating to shake handle 1, makes the wheel Wheel-chair keep continuously operation forward.
