Abstract
The invention relates to a push rod type single-hand direction control mechanism for a manually propelled wheelchair. The push rod type single-hand direction control mechanism for the manually propelled wheelchair comprises a front wheel outer shell, a front wheel, a belt, a belt pulley, a fixing frame, a T-shaped rod, a push rod and a push rod fixing outer shell, wherein the belt pulley is in transmission connection with the front wheel outer shell through the belt, the belt pulley is connected with the fixing frame through a rotary shaft, the T-shaped rod is fixedly connected in a central hole of the belt pulley, a transverse rod at the upper end of the T-shaped rod is embedded in a groove at the tail end of the push rod, the push rod penetrates through the push rod fixing outer shell and is in rotary connection with the push rod fixing outer shell, and the push rod fixing outer shell is installed on a front main shaft of the wheelchair and is in movable connection with the front main shaft of the wheelchair. According to push rod type single-hand direction control mechanism for the manually propelled wheelchair, in the process of achieving advancing or drawing back through swinging of a hand push rod, the T-shaped rod is driven to rotate through rotation of the push rod, flexible adjustment of the direction is achieved, and use is safe. The T-shaped rod is connected with the belt pulley, large-angle rotation of small wheels can be achieved, when the hand push rod operates and patient nursing is conducted, the small wheels of the wheelchair can rotate flexibly like small wheels of other wheelchairs, and the wheelchair is more convenient and flexible to use.
Description
Technical field
The present invention relates to a kind of singlehanded direction control mechanism for the push-down manual wheelchair, this mechanism can realize forward, in the rear drive, realize direction controlling function.
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, and owing to can't using traditional Manual wheelchair vehicle, greatly impact is known clearly these crowds' quality of life.Therefore, need the one-sided hand-driven Manual wheelchair vehicle of design, however this wheel-chair exists a push rod to drive simultaneously and controlling party to a difficult problem.
Summary of the invention
The present invention for the driving that solves one-sided hand-driven Manual wheelchair vehicle and controlling party to technical problem, and provide a kind of push-down manual wheelchair singlehanded direction control mechanism, this wheel-chair can realize forward by an one-sided push rod, to rear drive the time, realize direction controlling function.
For achieving the above object, technical scheme of the present invention is: the singlehanded direction control mechanism of a kind of push-down manual wheelchair, comprise front hub cap, front-wheel, belt, belt pulley, fixed mount, T word bar, push rod, push rod fixed housing, be characterized in: belt pulley is in transmission connection by belt and front hub cap; Belt pulley is connected with fixed mount by rotating shaft, be fixedly connected with T word bar in the belt pulley centre bore, T word bar upper end cross bar is embedded in push rod end groove, push rod passes the push rod fixed housing, and be rotationally connected with fixed housing, fixed housing is arranged on the wheelchair forward spindle, and is flexibly connected with the wheelchair forward spindle.
T word bar is fixedly connected with by key with belt pulley; T word bar cross bar is concentric with the wheelchair forward spindle.In the process that push rod shakes, T word bar is connected groove contact and is connected with the push rod end.
The invention has the beneficial effects as follows:
Handspike of the present invention can drive T word bar by rotating push-rod and rotate in shaking the process that realizes advancing or retreat, and realizes the flexible of direction, uses safer.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.
Description of drawings
Fig. 1 is that structure of the present invention is always schemed;
Fig. 2 is the groove structure schematic diagram of push rod end.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is done step explanation:
As Fig. 1, shown in 2, the singlehanded direction control mechanism of push-down manual wheelchair of the present invention comprises front hub cap 1, front-wheel 2, belt 3, belt pulley 4, fixed mount 5, T word bar 6, push rod 7, push rod fixed housing 8.
Belt pulley 4 is in transmission connection by belt 3 and front hub cap 1; Belt pulley 4 keeps interlock by belt 3 and front hub cap 1; Belt pulley 4 is connected with fixed mount 5 by rotating shaft, is fixedly connected with T word bar 6 in belt pulley 4 centre bores, and T word bar 6 is connected with belt pulley 4 keys; T word bar 6 upper end cross bars are embedded in push rod 7 end grooves, and push rod 7 passes push rod fixed housing 8, and are rotationally connected with fixed housing 8, can relatively rotate.Fixed housing 8 is arranged on wheelchair forward spindle 9, and is flexibly connected with wheelchair forward spindle 9.T word bar (6) cross bar is concentric with wheelchair forward spindle 9.
As shown in Figure 2, the groove of push rod end can make to turn to flexibly.In the process that push rod shakes, the groove of T word bar 6 and push rod 7 ends remains and contacts, and when push rod 7 rotates in certain angle, can drive T word bar 6 and rotate, and then drive the front-wheel rotation, realizes steadily turning to flexibly.
