Abstract
The utility model relates to a long-handle driving three-wheel bicycle. The length of a driving handle 1 is from 60 to 80 cm, the tail end of the handle is fixed on a front driving shaft 2, a ratchet wheel 7 and a ratchet pawl 8 are arranged on a chain disk 3, and the chain disk 3 is also fixed on the front driving shaft 2 by the ratchet wheel 7. The gear number ratio of the chain disk 3 and a back chain wheel 5 is 4-8: 1. The three-wheel bicycle can continuously run forwards by pushing the driving handle 1 forwards and backwards by hands. Because the extended driving handle can save labor, users can easily drive the three-wheel bicycle.
Description
Technical field
A kind of long handgrip of the utility model drives tricycle, belongs to non-motorized vehicles, has particularly a kind ofly carried out improving design-calculated, mainly for the hand-drive tricycle of physical disabilities or the elderly's use.
Background technology
The driving handgrip of existing hand-drive tricycle is generally shorter, and according to lever principle, handgrip is long more laborsaving more, but existing hand-drive tricycle is made the circular movement handle with hand and is driven, therefore, drive handgrip and can not do oversizely, generally be about 16cm.
Summary of the invention
The utility model is changed the mode of driving of the physical construction and the rotation handle of existing hand-drive tricycle handgrip, and a kind of tricycle that drives with the lengthening handgrip is provided, and purpose is that the user was more laborsaving when it was travelled.
The length of the driving handgrip 1 of said hand-drive tricycle is 60～80cm, and this handgrip end is fixed on the drive axle 2; Ratchet 7 and ratchet 8 are installed on the chain dish 3, and also are fixed on the drive axle 2 by ratchet 7; In order to guarantee normal road speed, chain dish 3 is 4～8: 1 with the ratio of number of teeth of back sprocket wheel 5.
The utility model drives handgrip 1 with push-and-pull before and after the hand, tricycle is turned round continuously to move ahead, rather than the handgrip of the existing hand-drive tricycle of picture drives to travel as circular movement, owing to make a long driver to start can be laborsaving, so especially physical disabilities and the elderly can too big power and drive to travel for the user.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is a structure enlarged diagram between ratchet, ratchet and the chain dish.
The specific embodiment
Now in conjunction with the accompanying drawings 1 and accompanying drawing 2 specify implementation process of the present utility model.The length that drives handgrip 1 is 60～80cm, is good with 65cm usually.Its end is fixed on the drive axle 2.Ratchet 7 and ratchet 8 are installed on the chain dish 3, are fixed on the drive axle 2 by ratchet 7.
When travelling, only with hand promotes forward to drive handgrip 1, and coupled drive axle 2 is rotated, and drives 3 rotations of chain dish by ratchet 7 and ratchet 8, by chain 4 wheel 6 is moved ahead again.In order to guarantee normal road speed, chain dish 3 is 4～8: 1 with the ratio of number of teeth of back sprocket wheel 5, is good with 6: 1.Hand pulls back when driving handgrip 1, though drive axle 2 also rotates backward, does not produce propulsive effort when ratchet 7 and ratchet 8 counter motions, so wheel 6 can not retreat.Drive handgrip 1 with push-and-pull before and after the hand, tricycle is turned round continuously move ahead, rather than the handgrip of the existing hand-drive tricycle of picture drives to travel as circular movement.Because the driving handgrip of lengthening can be laborsaving, so especially physical disabilities and the elderly's user can drive to travel by low weight loose ground.Originally make a long driver to start also being installed on the two-wheeled cycle.
Claims (1)
1. one kind long handgrip drives tricycle, and it is characterized in that: the length of the driving handgrip (1) of said tricycle is 60～80cm, and this handgrip end is fixed on the drive axle (2).
