Abstract: A shock absorbing structure comprises: a cylinder, a valve, a moveable tube, an adjusting tube and a valve rod. The valve rod, the adjusting tube and the moveable tube are coaxially arranged in a telescopic manner. The valve is fixed at an end of the moveable tube, and cooperates with an oil path to divide the cylinder into an oil pressure space and an air pressure space. Another end of the moveable tube cooperating with the adjusting tube and the valve rod protrudes out of the cylinder. The moveable tube is further provided with an oil return path. With the abovementioned arrangements, the user can turn on or off the buffering function of the shock absorbing structure freely. Furthermore, the operations of adjusting and turning on/off the buffering effect are all performed at the same end of the shock absorbing structure, therefore, the shock absorbing structure of the present invention is more suitable for modularization and is more simply structured.

Abstract: A shock absorbing device has an outer tube, a sliding tube, an inner tube, a piston and a flow controlling valve. An oil passage is defined between the outer tube, the sliding tube and the inner tube and is filled with oil. The flow controlling valve is attached to the inner tube to control the oil flow in the oil passage and has a plug, a valve body, a valve rod, a valve disk and a biasing member. The valve body is attached to the plug and has a central passage and a side opening communicating with the central passage. The valve rod is rotatably mounted into the central passage, and a tiny gap is defined between the central passage and the valve rod. A flow notch is defined in the valve rod and selectively aligns with the side opening when the valve rod is rotated.
