Description
Technical field
The present invention relates to a kind of wheel-chair, the wheel-chair that especially a kind of one-sided upper limb disorder or hemiplegic patient use.
Background technology
Along with China's aged tendency of population, limbs disturbance appears in the crowd more and more, needs to use wheel-chair as walking-replacing tool.In the autonomous Manual wheelchair vehicle that drives, most of traditional push chairs can only make with the hands and drive.Yet a lot of limbs disturbance persons only have one-sided hands function normal, so this part crowd can't use these traditional Manual wheelchair vehicles.Particularly in recent years, patients with cerebral apoplexy crowd quantity increases substantially, and this class patient major part is the hemiplegic patient, and wherein great majority only have again one-sided hands function normal, owing to can't using traditional Manual wheelchair vehicle greatly to affect these crowds' that know clearly quality of life.Therefore, some having occurred in the world in recent years can one-sided hand-driven Manual wheelchair vehicle, yet there is following defective in these external one-sided hand wheelchairs: in stays in (1) hand process; (2) angle of steamboat rotation is restricted, dumb; (3) can not to rear drive, there be very large use inconvenience.
Summary of the invention
The present invention exists in order to solve existing one-sided hand wheelchair: in stays in (1) hand process; (2) angle of steamboat rotation is restricted, dumb; (3) can not have the technical problem of very large use inconvenience, and provide a kind of one-sided push-down formula wheel-chair capable of free rotation to rear drive, this wheel-chair can realize forward by an one-sided push rod, to rear drive and direction controlling function.
for achieving the above object, technical scheme of the present invention is: a kind of one-sided push-down formula wheel-chair capable of free rotation, comprise front hub cap, front-wheel, cog belt, belt wheel, fixed mount, T word bar, push rod, the push rod fixed housing, the commutation gauge tap, large flywheel, main shaft, chain, small flywheel, diverter, drive sprocket, be characterized in: belt wheel is arranged on fixed mount, and be in transmission connection by cog belt and front hub cap, be fixedly connected with T word bar in the middle of belt wheel, T word bar upper end cross bar partly is embedded in push rod end groove, and T word bar cross bar part is concentric with the wheelchair forward spindle, push rod passes the push rod fixed housing, and is rotationally connected with the push rod fixed housing, forms singlehanded direction control mechanism, is used for realizing carrying out front-wheel steer when the push rod driving is advanced, be fixedly connected with large flywheel on main shaft, large flywheel is in transmission connection by chain and small flywheel, forms drive transmission device, be rotationally connected diverter in the push rod fixed housing, drive sprocket is fixed on main shaft, diverter and the commutation gauge tap control connection that is arranged on the push rod upper end, and being connected between diverter and drive sprocket forms a ratchet mechanism.
Be provided with brake lever above push rod, brake lever is connected with rear wheel brake by the wire that passes push rod, is used for realizing the wheel-chair brake.
Drive sprocket is fixedly connected with by key with main shaft.Diverter is connected with the commutation gauge tap by the wire that passes push rod.
The invention has the beneficial effects as follows:
Main core technology of the present invention is steering mechanism and drive mechanism, designs on the shortcoming of original device and can advance or retreat overcoming, and can turn in rotation process.The technical scheme that proposes around core technology: 1. singlehanded direction control mechanism, its innovative point is, singlehanded direction control mechanism: (1) handspike is in back and forth shaking the process that realizes advancing or retreat, can drive T word bar by rotating push-rod rotates, realize the flexible of direction, use safer.(2) T word bar is connected with belt wheel, can realize the steamboat large rotation angle, and in handspike work, during patient care, the wheelchair steamboat also can look like the steamboat flexible rotating of other wheelchairs, and is more convenient and flexible.2. drive transmission device: (1) push rod drives ratchet, advances or retreats by hand realization, can bring convenience to user, and the control by switch makes advances or retreats very flexibly, and has good stability.(2) ratchet band movable sprocket, the hand-operated mechanism of chain-type uses one-sided, and can drive the rotation of both sides bull wheel by sprocket wheel, makes rotation more steady.This wheelchair has also kept the better function of the existing Wheelchair structure in market in addition, and rear backrest can be put down, can the short time lie down, anti-tip wheel has certain defencive function to user, the mechanism of feet can lifting, uses more comfortablely.
The present invention is a kind of traditional push chairs that is different from, and is fit to most of user, especially for one-sided upper limb disorder or hemiplegic patient.The wheel-chair of this new design can allow the sound people's individual operation wheelchair of one-sided upper limb, and particularly it adopts frame for movement to realize that one-sided hand push rod drives fully, realizes forward, to rear drive and direction controlling function, for patient's life brings very large change.This technology belongs to the rehabilitation engineering field of medical apparatus and instruments.
Characteristics of the present invention:
(1) the one-sided upper limb person of perfecting can use.
(2) push rod and direction are controlled one.
(3) push rod is realized advancing or retreating by on-off control.
(4) back can fall, for having a rest.
(5) handrail height is adjustable.
