Push rod type single-hand direction control mechanism for manually propelled wheelchair

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 [0001] The invention relates to a one-handed direction control mechanism for a push rod type manual wheelchair, which can realize the direction control function while realizing forward and backward driving. Background technique [0002] With the aging population in our country, more and more people have limb dysfunction and need to use wheelchairs as a means of transportation. In self-propelled manual wheelchairs, most traditional wheelchairs can only be driven with both hands. However, many people with physical disabilities only have normal function of one hand, so these people cannot use these traditional manual wheelchairs. Especially in recent years, the number of stroke patients has increased significantly. Most of these patients are hemiplegic patients, and most of them only have normal function of one hand. The inability to use traditional manual wheelchairs has greatly affected the life of these people. Quality of Life. Therefore, it is necessary t...

However, many people with physical disabilities only have one hand functioning normally, so these people cannot use these traditional manual wheelchairs

Especially in recent years, the number of stroke patients has increased significantly. Most of these patients are hemiplegic patients, and most of them only have normal function of one hand. The inability to use traditional manual wheelchairs has greatly affected the health of these people. Quality of Life

Therefore, it is necessary to design a manual wheelchair driven by one hand, but this wheelchair has the problem of driving and controlling the direction at the same time with a push rod
