Abstract
A wheelchair with warm keeping protective bands comprises a wheelchair body, the warm keeping protective bands are arranged at the front end of the wheelchair body, and the two ends of the warm keeping protective bands are provided with connecting ropes for fastening the warm keeping protective bands on the wheelchair body conveniently. The wheelchair body is further provided with a speed limiting device, and the speed limiting device comprises a centrifugal wheel, a spring, a centrifugal pin, a big belt wheel, a small belt wheel and a driving wheel, wherein the big belt wheel, the small belt wheel and the driving wheel are linked through a belt. The centrifugal wheel is driven to rotate through the rotation of a rear wheel of the wheelchair body sequentially through the driving wheel, the big belt wheel and the small belt wheel, and the centrifugal pin makes contact with the ground under the action of centrifugal force to generate friction to perform a speed limiting effect. According to the wheelchair with the warm keeping protective bands, through the arrangement of the warm keeping protective bands, a function of defending against the cold is performed, and a patient is prevented from sliding off the wheelchair; due to the fact that the speed limiting mechanism is arranged, the speed of the wheelchair can be controlled effectively, and danger can be avoided.
Description
Technical field
The present invention relates to a kind of wheelchair, especially relate to a kind of wheelchair with warming protecting band.
Background technology
Wheelchair is a kind of important rehabilitation instrument, it is not only the walking-replacing tool of limbs the disabled, and can make them by carrying out physical exercise and participate in social activity, for the user wheelchair excessive velocities with wheelchair, not only easily produce danger, and be unfavorable for Rehabilitation.
Summary of the invention
The object of the invention is the problem that is easily subject to cold wind impact when wheelchair excessive velocities easily produces dangerous and outdoor use for solving, a kind of wheelchair with warming protecting band is provided, the present invention not only plays the effect of resisting cold by the warming protecting band arranging, avoided patient's slippage from wheelchair simultaneously, and be provided with speed limiting mechanism, effectively control wheelchair speed, avoid producing dangerous.
The present invention is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
A kind of wheelchair with warming protecting band, comprise wheelchair body, the front end of wheelchair body is provided with warming protecting band, warming protecting band two ends are provided with is convenient to warming protecting band to be fixed on the connecting rope on wheelchair body, on described wheelchair body, be also provided with speed-limiting device, speed-limiting device comprises centrifugal wheel, spring, centrifugal lock and the big belt pulley linking by belt, small belt pulley and drivewheel, wherein, big belt pulley and small belt pulley are arranged on the support of wheelchair body, the trailing wheel of drivewheel and wheelchair body is with rotating shaft setting, centrifugal wheel and small belt pulley are with rotating shaft setting, centrifugal lock is arranged in the groove radially distributing on centrifugal wheel, and be connected with the spring of active force sensing centrifugal wheel axis of rotation, drivewheel is passed through in the rotation of wheelchair body trailing wheel successively, thereby big belt pulley drives centrifugal wheel rotation to make centrifugal lock under centrifugal action, contact generation friction with ground with small belt pulley and plays speed limit effect.
On the sidewall of described wheelchair body, the hook for hanging drainage bag is installed.
Described centrifugal wheel is positioned at the top of wheelchair body front-wheel and trailing wheel least significant end line.
The invention has the beneficial effects as follows: the present invention not only plays the effect of resisting cold by the warming protecting band arranging, avoided patient's slippage from wheelchair simultaneously, and be provided with speed limiting mechanism, effectively controls wheelchair speed, avoid producing dangerous.
Accompanying drawing explanation
Fig. 1 structure diagram of the present invention.
Graphical indicia: 1, hook; 2, warming protecting band; 3, connecting rope; 4, wheelchair body; 5, big belt pulley; 6, drivewheel; 7, spring; 8, centrifugal lock; 9, small belt pulley; 10, centrifugal wheel.
The specific embodiment
Shown in figure, the specific embodiment is as follows:
A kind of wheelchair with warming protecting band, comprise wheelchair body 4, the front end of wheelchair body 4 is provided with warming protecting band 2, warming protecting band 2 two ends are provided with is convenient to warming protecting band 2 to be fixed on the connecting rope 3 on wheelchair body 4, on described wheelchair body 4, be also provided with speed-limiting device, speed-limiting device comprises centrifugal wheel 10, spring 7, centrifugal lock 8 and the big belt pulley 5 linking by belt, small belt pulley 9 and drivewheel 6, wherein, big belt pulley 5 and small belt pulley 9 are arranged on the support of wheelchair body 4, the trailing wheel of drivewheel 6 and wheelchair body 4 is with rotating shaft setting, centrifugal wheel 10 and small belt pulley 9 are with rotating shaft setting, centrifugal lock 8 is arranged in the groove radially distributing on centrifugal wheel 10, and be connected with the spring 7 of active force sensing centrifugal wheel 10 axis of rotation, the rotation of wheelchair body 4 trailing wheels is successively by drivewheel 6, thereby driving centrifugal wheel 10 to rotate, big belt pulley 5 and small belt pulley 9 centrifugal lock 8 is contacted with ground under centrifugal action produce friction to play speed limit effect.
Described centrifugal wheel 10 is positioned at the top of wheelchair body 4 front-wheels and trailing wheel least significant end line.
The present invention in use, if when user is sitting in outside, top cold, warming protecting band can be loaded onto and be fixed on wheelchair by connecting rope, if the not used time, warming protecting band can be taken off and be placed on the fooled mat use of wheelchair, the speed limiting mechanism arranging simultaneously, in the time of wheelchair excessive velocities, the active force that can make centrifugal lock overcome spring stretches out centrifugal wheel, and contacts generation frictional force with ground, thereby slows down wheelchair speed.
The technical scheme that the present invention is cited and embodiment are not restrictions, in the cited technical scheme of the present invention and embodiment is equal to or effect same approach is all protected in the present invention scope.
