Description

Wheelchair pedal lifting device

Technical Field

The utility model relates to the technical field of wheelchairs, in particular to a wheelchair pedal lifting device.

Background Art

A wheelchair is a chair with wheels that can help replace walking. It is an important means of transportation for the injured, sick, and disabled for home rehabilitation, turnover transportation, medical treatment, and outdoor activities. A wheelchair not only meets the transportation needs of the physically disabled and those with limited mobility, but more importantly, it makes it easier for family members to move and care for the patients, and enables the patients to use wheelchairs for physical exercise and participate in social activities.

In the prior art, wheelchairs are important tools to help people with limited mobility to move around, and the most common place for wheelchairs is hospitals. There are many wheelchairs in the inpatient department of a hospital to help patients with limited mobility to move around. The wheelchairs in the hospital are all of the same model, and the pedals and brackets of the wheelchairs are fixed together. This results in some patients being unable to place their feet on the pedals due to differences in body shape, causing discomfort to the patients. Patients with leg diseases may even have their conditions aggravated due to the lack of support for their legs, leading to delayed recovery. Therefore, we propose a wheelchair pedal lifting device.

A foot pedal 98 is arranged on the opposite side of the movable connecting block 97. A bearing plate 99 is arranged on the opposite side of the installation box 91 and below the foot pedal 98.

Example 2

As shown in Figures 1-3, the power box 8 is bolted to the bracket 1, the installation box 91 is bolted to the power box 8, the bearing plate 99 is bolted to the power box 8, and the bearing plate 99 is bolted to the installation box 91, so that the lifting mechanism 9 can operate stably, the drive motor 92 is bolted to the installation box 91, the screw rod 93 is rotatably connected to the installation box 91, and the screw rod 93 is bolted to the output end of the drive motor 92, which can effectively provide power for the lifting of the footrest 98, the sliding block 95 is threadedly connected to the screw rod 93, the sliding block 95 is slidably connected to the oblique guide rail 94, and the fixed connecting column 96 is threadedly connected to the sliding block 95, which can effectively provide a stable connection for the footrest 98, the footrest 98 is bolted to the movable connecting block 97, and the movable connecting block 97 is rotatably connected to the fixed connecting column 96, which can facilitate the folding of the footrest 98, the drive motor 92 is powered by the battery 11, and the drive motor 92 is controlled by the lifting button 6, which can effectively adapt to the height of the patient.

The working process of the present invention is as follows: when using a wheelchair pedal lifting device to lift the foot, first, lift the patient onto the bracket 1 so that the patient's legs are located above the supporting plate 99. If the patient's legs are long, the position of the footrest 98 will cause the patient's legs to be bent and unable to stretch. At this time, lift the footrest 98 to make the movable connecting block 97 rotate in the fixed connecting column 96 and fold it up. At this time, the patient can place his feet on the supporting plate 99 so that the legs are supported and can be stretched out at the same time. If the patient's legs are shorter, the lifting button 6 on the armrest 5 controls the battery 11 to power the drive motor 92, so that the drive motor 92 drives the screw rod 93 to rotate inside the installation box 91, thereby driving the sliding block 95 to slide in the oblique guide rail 94 to drive the footrest 98 to move until it is adjusted to a position that can support the sole of the patient's foot. The present invention can effectively lift and lower the pedal of the wheelchair through design, so as to effectively adapt to patients of different body shapes and effectively support the patient's legs.
