Abstract
The utility model relates to a low-ankle energy storage artificial foot core, which comprises a metal ankle connecting piece, wherein a Z-shaped structure formed by a carbon fiber bottom plate, a metal heel block and a carbon fiber back heel piece from top to bottom is arranged below the metal ankle connecting piece, wherein a front buffering block is arranged between the front part of the metal ankle connecting piece and the middle part of the carbon fiber bottom plate; and a back buffering block is arranged between the back part of the metal ankle block and the middle part of the carbon fiber back heel piece; according to the utility model, in the push-off process of heels and soles of a user, the resilience force generated after the elastic deformations of the carbon fiber bottom plate and the carbon fiber back heel piece is helpful to walking; as the front buffering block and the back buffering block are additionally arranged in the foot core, a defect that the height of the foot core is excessively reduced when the weight of the user is increased or the user carries heavy objects, stronger stability is obtained and the height of the integral foot core is not more than 60 mm; and the low-ankle energy storage artificial foot core can also be even assembled to amputees with separated ankle joints; therefore, the low-ankle energy storage artificial foot core provided by the utility model has the advantages of wider application range, long service life, strong stability, strong applicability, wide application range and low production cost.
Description
Technical field
This utility model relates to the prosthesis technique field, relates in particular to a kind of low ankle energy saving foot core for artificial foot of the problems such as short, stable and poor for applicability, the narrow application range of nature, service life of difficulty in walking that existing foot core for artificial foot exists in use that solved.
Background technology
For the patient of lower extremity amputation, false foot is that it configures the important functional parts in the artificial limb.Present state maternity leave foot mostly is the materials such as wood, engineering plastics, rubber, polyurethane and makes, it replaces the effect of normal foot function relatively poor, enter when pushing off the phase very not natural and tripping at user from midstance, forward edge and the stress between carbon fiber base plate contact point of upper metal ankle connector are comparatively concentrated simultaneously, cause the service life of foot core very short, increased burden to user; The heel of existing foot core distortion is serious in use, lack can produce when foot is pedaled ground pedal the ground counteracting force, this causes the user use very inconvenient, and is stable and the suitability is very poor; In addition, existing foot core can only be used for the crowd of high amputation, can not use from disconnected amputee ankle joint, and versatility is very poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of walking to make things convenient for the low ankle energy saving foot core for artificial foot that nature, long service life, stability and the suitability are strong, applied widely and production cost is low.
The purpose of this utility model is achieved in that a kind of low ankle energy saving foot core for artificial foot, comprise metal ankle connector, the below of described metal ankle connector be disposed with from top to bottom carbon fiber base plate, metal with piece and carbon fiber after heel piece form word shape structure, wherein metal ankle connector anterior with carbon fiber base plate middle part between be provided with front buffer stopper, metal arranges rear buffer stopper between in the middle part of the heel piece after with piece rear portion and carbon fiber.Be connected by upper connecting bolt between the rear end of described metal ankle connector and the rear end of carbon fiber base plate.
Described metal is connected by lower connecting bolt with the front end of heel piece behind the front end of piece and the carbon fiber, and the rear end of heel piece tilts downwards behind the carbon fiber.
The integral body of described carbon fiber base plate is the arc shape structure, and the middle front part of carbon fiber base plate is to be provided with minute toe shape structure that longitudinally hits exactly distribution groove.
