Summary of the invention:
The object of the present invention is to provide the false lower limb that a kind of structure is simple, easy to install.
Technical scheme of the present invention is as follows: it comprises and limb connection part, play support bar and the foot plate of shank effect, it is characterized in that: described limb connection part adopts frame structure, described frame structure comprises longitudinal holding pole and horizontal ring for fixing, the column framework that to match with the contact site of human body deformed limb is surrounded by some described longitudinal holding poles, be provided with the horizontal ring for fixing some longitudinal holding poles being connected into entirety above together in the horizontal direction, be positioned in the bottom outside of limb connection part the mode that the position on rear side of human body knee joint is connected through the hinge to be connected with the top of described support bar, the bottom of described support bar is connected on rear side of the upper surface of the sole similar to human body sole shape.
The present invention have structure simply light and handy, easy to install, use flexibly, rugged road walked freely, cost is low, lightweight advantage.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation under the present invention is in flexural deformation state.
Fig. 3 is the cross-sectional view of elastic supporting bar.
Label declaration: 1 longitudinal holding pole, 2 horizontal ring for fixings, 3 support bars, 4 soles, 5 elastic supporting bars, 6 outer sleeves, 7 springs, 8 instep support bars, 9 first pin joints, 10 second pin joints, 11 the 3rd pin joints, 12 the 4th pin joints, 13 cushion pads, 14 elastic strips.
Detailed description of the invention:
As shown in Figure 1, the present invention includes limb connection part, play support bar 3 and the foot plate of shank effect, it is characterized in that: described limb connection part adopts frame structure, described frame structure comprises longitudinal holding pole 1 and horizontal ring for fixing 2, the column framework that to match with the contact site of human body deformed limb is surrounded by described some longitudinal holding poles 1, horizontal ring for fixing 2 is fixed with on the top of longitudinal holding pole 1, also ring for fixing is provided with at the middle part of some longitudinal holding poles 1, be positioned in the bottom outside of limb connection part the mode that the position on rear side of human body knee joint is connected through the hinge to be connected with the top of described support bar 3, form the first pin joint 9, make to rotate arbitrarily around hinged turning cylinder between limb connection part and support bar 3, the bottom of described support bar 3 is connected on rear side of the upper surface of the sole similar to human body sole shape.Be set to two-part in the lower end of described support bar 3, be connected through the hinge between these two sections, form the second pin joint 10.Sole can be swung up and down around this hinge connection.
Human body lower limbs action is more met in order to enable the result of use of artificial limb, obliquely between in the middle part of the bottom and instep of support bar 3 epimere be provided with elastic supporting bar 5, the two ends of described elastic supporting bar 5, respectively by the lower end and the sole upper surface that are hingedly connected at epimere support bar 3, form the 3rd pin joint 11 and the 4th pin joint 12 thus; Described elastic supporting bar 5 is by outer sleeve 6, the instep support bar 8 being located at the spring 7 in outer sleeve 6 and being located in spring, described instep support bar 8 is two, wherein one end of one is connected with support bar 3, one end of another root is connected with the upper surface of sole 4, their other end relatively unsettled setting between two, and be provided with gap between their opposite face, the size in gap equals or under being in walking states slightly larger than sole or when doing under other active state, the maximum tension stroke of elastic supporting bar 5.Described outer sleeve is made up of rigid material, and described rigid material is duroplasts or the light metal material of rigidity.
Be provided with elastic strip 14 in the front of described limb connection part and support bar 3, one end of described elastic strip 14 is connected to the front of limb connection part, and the other end is connected to the front of support bar 3.
In order to reduce vibrations, the contact surface of limb connection part and support bar is provided with cushion pad 13.
In order to prevent the distortion of sole, increasing the intensity of sole, being provided with reinforcement at the upper surface of sole.
In order to improve comfort level when limb connection part and extremity, be provided with flexible materials at the framework inner surface of extremity part.
As shown in Figure 1, in order to make false lower limb more true to nature in the use procedure of walking, the front end of sole is set to the structure upwarped.In order to make false lower limb external form more as limbs, be coated with support bar surrounding layer in the outside of support bar.Described support bar surrounding layer top is below provided with breach, so that false lower limb knee joint position (i.e. limb connection part and support bar junction), when limb connection part is bent downwardly, maximum bending limit can be reached, for providing space when limb connection part bends.
In order to make false lower limb external form more as limbs, be coated with instep surrounding layer in the outside of sole.
