CN2400072Y - Improved knee joint - Google Patents

The utility model relates to a modified knee joint, its characteristic mainly is that utilize the axle center to cup joint the rotating part in the knee joint main part, it is rotatory as the center to let the rotating part use the axle center, one-way bearing is put into to the rotary device of its rotating part, when letting the rotating part reply with anticlockwise, utilize buffer's restoring force and the one-way bearing of rotating part, and the reply normal position that can be quick, when the rotating part is with clockwise bending, utilize buffer and great frictional force, and can slow bending, by this action that comes and goes, let the disabled personage can effectual application artificial limb, it is more convenient to make the action.

Improved knee joint

This utility model relates to a kind of artificial limb knee-joint device, and the artificial limb that particularly a kind of individuals with disabilities of allowing uses can be more convenient and the improved knee joint of safe handling.

Individuals with disabilities in the society now, can increase its action property by the artificial limb structure, and be to make artificial limb work out knee joint structure then as the bending walking of foot as the foot knee, allow artificial limb more as the bending of people's foot walking, allow the more convenient walking of individuals with disabilities by this artificial limb; Though yet the artificial limb knee-joint structure has and the foot identical functions; because artificial limb is a kind of frame for movement all the time; need individuals with disabilities's utilization to lift actions such as lower limb and swing; effectively motion; but knee joint structure now; as No. the 203742nd, Taiwan patent announcement " kneed improvement structure "; its Fastening device utilizes rotating shaft; allow the Fastening device be center rotation with the axostylus axostyle; because artificial limb is not the some of own health eventually; uncontrollable quite flexible, thus usually can be when wanting crooked rotation too fast, cause as angle can't the application of force compressing the packing cover when excessive; cause artificial limb to bend to the right angle fast; allow the individuals with disabilities not have to support and fall injured, and when bending after homing very fast, allow the individuals with disabilities can only the small step walking etc. use inconvenience and unsafe problems.

The purpose of this utility model is that a kind of improved knee joint will be provided, and promptly provides a kind of crookedly slowly in clockwise, replys knee joint structure fast counterclockwise.

The purpose of this utility model is achieved in that

A kind of improved knee joint is characterized in that: socket one is the rotating part of center of rotation with this axle center on the axle center of this knee joint main body; This rotating part mainly includes a rotary apparatus, and a unilateral bearing is set in this rotary apparatus, and the rear end of this rotary apparatus links to each other with buffer unit upper end; This kneed rotating part is the slow shape that is rotated counterclockwise fast and turns clockwise.

A gum elastic is installed in this knee joint main body top.

This utility model mainly is to insert unilateral bearing in the rotary apparatus, it utilizes the restoring force of buffer unit and the unilateral bearing of rotating part when allowing rotating part with counterclockwise answer, and homing fast, when rotating part utilizes buffer unit and bigger friction when crooked and can be crooked slowly with clockwise, by this action that comes and goes, allow the individuals with disabilities effectively use artificial limb, make action more convenient.

This utility model structure flexibly, apply on individuals with disabilities's the artificial limb more convenient, the safety of its action.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.

Description of drawings:

Fig. 1 is the kneed perspective view of this utility model;

Fig. 2 is the cutaway view at place, this utility model axle center;
