[0002] 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 convenient for family members to move and care for the patients, allowing the patients to exercise and participate in social activities with the help of wheelchairs. It is an auxiliary mobile device that provides a safe and convenient way to restore some people's independence. The anti-tilt wheels are used on wheelchairs and installed on the frame, mainly to provide auxiliary stability and support.

[0003] At present, in many cases, in order to prevent the wheelchair from tipping over, it is necessary to equip the wheelchair with an anti-tip wheel device; however, ordinary anti-tip wheel devices are often fixed in one direction, which is difficult to meet the use needs of different users in different occasions. Sometimes the anti-tip wheel needs to be flipped up to avoid obstacles or reduce space. At this time, the anti-tip wheel needs to be removed and reinstalled, which is very inconvenient.

[0004] Therefore we propose a reversible anti-tilt wheel for a wheelchair, so as to solve the above-mentioned problems. Utility Model Content
