Abstract
The utility model relates to a single-side hand-operated wheelchair direction control device which comprises a front wheel outer shell, a front wheel, a belt, a belt wheel, a fixed frame, a T-shaped rod, a pushing rod and a pushing rod fixed outer shell. The belt wheel is connected with the front wheel outer shell through the belt in a transmission mode, the belt wheel is connected with the fixed frame through a rotating shaft, the T-shaped rod is fixedly connected in a center hole in the belt wheel, a cross rod at the upper end of the T-shaped rod is embedded in a groove in the tail end of the pushing rod, the pushing rod penetrates through the pushing rod fixed outer shell and is connected with the fixed outer shell in a rotating mode, and the fixed outer shell is mounted on a front main shaft of a wheelchair and movably connected with the front main shaft of the wheelchair. According to the single-side hand-operated wheelchair direction control device, when a hand pushing rod is rolled to enable the wheelchair to go forwards or backwards, the pushing rod is rotated to drive the T-shaped rod to rotate to achieve flexible adjustment of directions, and the wheelchair can be used more safely. The T-shaped rod is connected with the belt wheel, large-angle rotation of a small wheel can be achieved, when the hand pushing rod works and a patient is nursed, the small wheel of the wheelchair can flexibly rotate like small wheels of other wheelchairs, and convenience and flexibility are achieved.
Description
Technical field
This utility model 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 control function.
Background technology
Along with China's aged tendency of population, limbs disturbance appears in the crowd more and more, needs to use the wheel Wheel-chair as walking-replacing tool.In the autonomous manual pulley Wheel-chair that drives, most of traditional push chairs can only make with the hands and drive.Yet a lot of limbs disturbance persons have only one-sided hands function normal, so this part crowd can't use these traditional manual pulley Wheel-chairs.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 have only one-sided hands function normal again, owing to can't use traditional manual pulley Wheel-chair, greatly influence is known clearly these crowds' quality of life.Therefore, need the one-sided hand-driven manual pulley Wheel-chair of design, however this take turns Wheel-chair exist a push rod to drive simultaneously and controlling party to a difficult problem.
Summary of the invention
This utility model for the driving that solves one-sided hand-driven manual pulley Wheel-chair and controlling party to technical problem, and provide a kind of one-sided manual pulley Wheel-chair direction-control apparatus, this Wheel-chair of taking turns can be realized forward by an one-sided push rod, to rear drive the time, realize direction control function.
For achieving the above object, the technical solution of the utility model is: a kind of one-sided manual pulley Wheel-chair direction-control apparatus, comprise preceding 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 preceding hub cap; Belt pulley is connected with fixed mount by rotating shaft, fixedly connected T word bar in the belt pulley centre bore, T word bar upper end cross bar is embedded in the terminal groove of push rod, push rod passes the push rod fixed housing, and be rotationally connected with fixed housing, fixed housing is installed on the wheelchair forward spindle, and flexibly connects with the wheelchair forward spindle.
T word bar is fixedlyed connected by key with belt pulley; T word bar cross bar is concentric with the wheelchair forward spindle.In the process that push rod shakes, the contact of the groove of T word bar and push rod end is connected.
The beneficial effects of the utility model are:
Handspike of the present utility model 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 rotation of steamboat wide-angle, and in handspike work, during patient care, the wheelchair steamboat also can rotate flexibly as the steamboat of other wheelchairs, and is more convenient and flexible.
Description of drawings
Fig. 1 is that structure of the present utility model is always schemed;
Fig. 2 is the groove structure sketch map of push rod end.
The specific embodiment
Do step explanation below in conjunction with accompanying drawing and this utility model of embodiment:
As Fig. 1, shown in 2, one-sided manual pulley Wheel-chair direction-control apparatus of the present utility model, 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 before comprising.
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.
