Description

Shock-absorbing wheel structure of ultra-light high-strength portable rehabilitation wheelchair Technical Field The utility model relates to a shock-absorbing wheel structure of an ultralight high-strength portable rehabilitation wheelchair. Background With the development of society and the aggravation of population aging, rehabilitation wheelchairs become an indispensable auxiliary tool in life of many people with inconvenient actions. The existing damping system of the rehabilitation wheelchair is relatively simple, and usually only depends on a simple damping device between wheels and a wheelchair main body, such as a spring or a rubber pad, and the damping modes have limited damping effect when facing complex road conditions, can not effectively filter jolts, easily cause discomfort and fatigue of users, and even possibly aggravate physical damage of the users. The wheel shock-absorbing structure of traditional wheelchair is more singlely, lacks the optimal design to wheel and wheelchair main part junction for wheelchair stability is not enough in the use, appears rocking or the condition of vibrations transmission easily, influences wheelchair's operability and security. Therefore, the shock-absorbing wheel structure of the ultra-light high-strength portable rehabilitation wheelchair is provided. Disclosure of utility model The utility model aims to provide a shock-absorbing wheel structure of an ultralight high-strength portable rehabilitation wheelchair, which aims to solve the problems that the wheel shock-absorbing structure of the traditional wheelchair is single, jolts cannot be effectively filtered, and discomfort and fatigue of a user are easily caused in the background art. In order to solve the technical problems, the utility model provides the technical scheme that the shock absorption wheel structure of the ultra-light high-strength portable rehabilitation wheelchair comprises two groups of wheels arranged at the front end of the ultra-light high-strength portable rehabilitation wheelchair, and the two groups of wheels are fixedly connected with the ultra-light high-strength portable rehabilitation wheelchair through a fixed cylinder; A damping component is arranged at the fixed cylinder, The wheel is used for carrying out shock absorption treatment on the ultra-light high-strength portable rehabilitation wheelchair through the shock absorption component. Preferably, the shock-absorbing assembly comprises a connecting frame connected with the wheels, a pressure-relieving rod is arranged at the top end of the connecting frame, and one end of the pressure-relieving rod is inserted into the fixed cylinder. Preferably, the outer periphery side of the buffering rod is provided with a buffering spring, and the buffering spring is positioned between the fixed cylinder and the connecting frame. Preferably, two sides of the lower part of the fixed cylinder are provided with extrusion wing plates, and the length of each extrusion wing plate is larger than the inner diameter of the damping spring, so that the extrusion wing plates extrude the damping spring. Preferably, a sealing lining cylinder is arranged on the upper portion of the inner wall of the fixed cylinder, a sealing plug is connected to the inner portion of the sealing lining cylinder in a sliding mode, and the lower portion of the sealing plug is connected with the pressure release rod through a connecting rod.
