Knee joint structure capable of preventing falling

Abstract

The invention provides a knee joint structure capable of preventing falling. The knee joint structure comprises a knee bearing seat, a main body seat and a connecting portion which are connected with one another; the knee bearing seat comprises a connecting part and two connecting rods and is connected to the position on the main body seat; connecting portion grooves are formed in the positions, corresponding to extension sections of two binding clamps, of one side of the connecting portion and used for containing abutting blocks, and the connecting portion is arranged under the main body seat in a penetrating mode through two fixing bolts to be connected to the position under the main body seat; a shaft core is arranged in the main body seat, two bearings, two one-way bearings, two lining covers and the binding clamps are sequentially arranged from the center of the shaft core to the two ends of the shaft core, the binding clamps are provided with the extension sections for being matched with the abutting blocks to clamp and loosen the shaft core, the shaft core is limited to rotate in one way through the one-way bearings, and then the pivot rotating angel of the shaft core is limited by the connecting part and the connecting rods. According to the knee joint structure capable of preventing falling, falling can be prevented in the walking action, and the purposes of preventing falling and simultaneously improving the overall safety are achieved.

Description

technical field [0001] The present invention relates to an anti-dumping knee joint structure, in particular to a structure for using a one-way bearing to cooperate with the shaft center when the user's knee joint of the prosthetic thigh support tube is walking, and the beam clamp and the abutment block are in contact with each other. The double restraint constituted by the top prevents the knee structure from toppling over. Background technique [0002] Unlike a healthy knee joint, the prosthetic thigh support has bones, ligaments and muscles to drive the complex connection between the thigh and the calf. It can only use the residual limb of the thigh to exert a slight force. Seemingly simple actions such as : Stretching exercises such as knee joint bending, straightening, squatting, and sitting down are difficult or even dangerous for users, because the knee joint and below the knee joint are all metal products, and metal products cannot be made such as Ligaments, muscles,...

AI Technical Summary

Problems solved by technology

[0004] Through the description of the aforementioned existing structure, it can be known that the prosthetic knee joint mainly restricts the rotation of the axis through the user's body weight or the reaction force contacting the ground to achieve its purpose, but mainly uses the beam clamp as the main Constraining structure, the degree of wear and tear of the beam clamp increases with the use time and the number of uses, common wear, bending deformation, breakage, etc., so it should be combined with different confinement structures or components to disperse the pressure, so that the various defects such as the above still remain There is room for further improvement
