Rain shielding wheelchair

Abstract

The invention discloses a rain-shielding wheelchair which comprises an awning inclined wind shielding mechanism, an awning is fixedly connected to the upper end of the awning inclined wind shielding mechanism, a rain-shielding area adjusting mechanism is arranged at the upper end of the awning, the awning inclined wind shielding mechanism comprises a top connecting supporting rod, and the top connecting supporting rod is fixed to the lower end of the awning. According to the rain-shielding wheelchair, the overall vertical inclination angle of the rain shielding cover is adjusted, when the inclination angle inclines downwards, wind pressure blown to a patient can be partially counteracted, the rain shielding cover cannot be horizontally arranged all the time to bear wind pressure resistance, and therefore the rain shielding cover can be prevented from being damaged. Meanwhile, when the awning inclines downwards, most of rainwater can be blocked, the situation that clothes of the patient are wetted by the rainwater along with guiding of the wind direction, the rainwater permeates into a postoperative wound to cause infection is avoided, and then the situation that the recovery of the illness state of the patient is affected due to a fever or other complications is prevented.
