Abstract
The utility model provides a comfortable and convenient crutch with the simple structure. The lower section of the crutch is provided with a shock absorbing device which consists of an upper rod 1 and a lower rod 2; wherein, the upper rod 1 is a cylinder and is provided with an upper pin clamp hole and a corresponding upper pin clamp, the lower rod 2 is cylindrical, the diameter of the lower rod is larger than that of the upper rod, a spring is arranged in the lower rod, a pin clamp moving hole is arranged on the cylinder wall of the lower rod which is near the upper part of the spring, and a lower pin clamp hole and a corresponding lower pin clamp are arranged on the cylinder wall of the lower rod which is near the lower part of the spring. The upper pin clamp can be moved up and down in the pin clamp moving hole. As the utility model is provided with the shock-absorbing device, when the human body imposes the pressure on the crutch, the pressure is acted on the spring to get the buffer, so as to reduce the shock and reduce the caused discomfort of the human body.
Description
One, technical field: this utility model relates to the instrument that a kind of people with disability of assistance walks, especially a kind of crutch.
Two, technical background: existing crutch is owing to lack damping device, and road is far away slightly, just can cause many uncomfortable reactions to user, and it is not too convenient to use.
Three, technical scheme: this utility model provides a kind of convenience simple in structure, comfortable can effectively alleviate the crutch of vibrations.The hypomere of crutch is provided with damping device, this device is made up of upper boom 1 and lower beam 2, upper boom 1 is for cylinder and be provided with pin card hole 3 and the corresponding pin card of going up, lower beam 2 is a cylindrical shape, following shank diameter is greater than upper boom, be provided with spring 4 in the lower beam, the lower beam barrel is provided with pin card movable span 5 near spring top, and the lower beam barrel is provided with lower pin card hole 6 and corresponding downside pin card near the spring bottom.The height of spring 4 is 5.5cm.The last external diameter of selling the length of card greater than lower beam 2, its two ends fixed by nut, last pin card can move up and down in pin card movable span 5, and the junction on upper boom 1 upper end and crutch top is provided with corresponding pin-and-hole and the pin of regulating height.Adopt after the said structure, owing to be provided with damping device, at human body to crutch during with pressure, pressure acts on the pin card by upper boom 1, because last pin card can move up and down in pin card movable span, pressure acts on spring 4 and obtains buffering, thereby has alleviated vibrations, has reduced the discomfort that human body is caused.
Four, description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of this utility model damping device.
Five, embodiment: the hypomere of crutch is provided with damping device, this device is made up of upper boom 1 and lower beam 2, upper boom 1 is for cylinder and be provided with pin card hole 3 and the corresponding pin card of going up, lower beam 2 is a cylindrical shape, following shank diameter is greater than upper boom, be provided with spring 4 in the lower beam, the lower beam barrel is provided with pin card movable span 5 near spring top, and the lower beam barrel is provided with lower pin card hole 6 and corresponding downside pin card near the spring bottom.The height of spring 4 is 5.5cm.The last external diameter of selling the length of card greater than lower beam 2, its two ends fixed by nut, last pin card can move up and down in pin card movable span 5.The junction on upper boom 1 upper end and crutch top is provided with corresponding pin-and-hole and the pin of regulating height.
