Description

The polyurethane active ankle

This utility model relates to a kind of polyurethane active ankle.

Existing false foot is timber, rubber structure.Promptly matching with ankle joint is positioned at behind the foot 2/3rds and is wooden foot core, foot bottom and foot first three/one be the rubber sole.Wooden foot core and rubber sole are adhesion-molded.The problem that exists is, easily comes unglued, easy fracture, compensation are poor, Heavy Weight, service life are short.

This utility model aims to provide a kind of polyurethane active ankle that makes false foot have good usability, good elasticity, wearability and sufficient intensity and threading property are arranged again.

This utility model is realized as follows, imitate foot earlier, the skeletal structure shape is given the wooden foot core of system, have garden platform shape groove shape buffer box above behind the wood foot core, arch of the foot position, middle part has garden shape connecting hole, fix the lining band of a rectangle fabric below the wood foot core front end by shoe tack, lining band stretches out outside the wooden foot core front end, in outside sufficient type body is wrapped in wooden foot core by the polyurethane mould castable, be the poroid nut groove in garden under the corresponding wooden foot core connecting hole on the foot type body, there is the ankle body cavity suitable with ankle part foot body upper end, buffer box on the wood foot core is in ankle body cavity rear portion, and connecting hole is positioned at ankle body cavity central part.

Be illustrated below in conjunction with accompanying drawing.

Fig. 1 is the front elevational view of this false foot.

Fig. 2 is the vertical view of this false foot.

In Fig. 1 and Fig. 2, the sufficient type body of 1 expression, the 2nd, buffer box, the 3rd, wooden foot core, the 4th, lining band, the 5th, nut groove, the 6th, ankle body cavity, the 7th, connecting hole, the 8th, shoe tack.This vacation foot uses when installing, buffer (a kind of false foot accessory) can be placed in the buffer box 2, the artificial limb ankle joint is packed in the ankle body cavity 6 of sufficient type body 1, ankle joint foot core screw passes the connecting hole 7 on the wooden foot core 3, to reach screw-driving in the nut groove 5 by nut, thus should the vacation foot and ankle joint be fixed together.

This utility model is owing to be fixed with lining band at the bottom of wooden foot core front end, be shaped by cast polyurethane then, false ball of foot threading property of portion of ankle and intensity increased, thereby can extend working time, and lining band also can increase the elasticity at sole position, and it is more freely comfortable that disabled people are used.
