Abstract
The utility model relates to an artificial lower limb which comprises a limb connecting portion, a support rod used as the shank, and a foot plate. The limb connecting portion is in a frame structure which comprises longitudinal support bars and transverse fixing rings. A plurality of longitudinal support bars are encircled to form a cylindrical frame body matched with a contact portion with a residual limb of a human body. More than one transverse fixing rings are arranged in the horizontal direction to connect the plurality of longitudinal support bars into a whole. A position, located on the rear side of a knee joint of the human body, of the outer side of the bottom of the limb connecting portion is connected with the top of the support rod in a hinged mode. The bottom of the support rod is connected with the rear side of the upper surface of the foot plate similar to a foot sole of the human body in shape. The artificial lower limb has the advantages of being simple and light in structure, convenient to install and use, flexible in use, capable of enabling a user to walk freely on a rugged road, low in cost and light in weight.
Description
Technical field:
This utility model relates to the lower limb that a kind of artificial limb relates in particular to a kind of vacation.
Background technology:
The progressively quickening of raising, Chinese society expanding economy and work rhythm along with people's living standard, automobile more and more becomes the vehicles that people be unable to do without, therefore the automobile on the road is more and more, therefore the speed of a motor vehicle is also more and more faster, and the generation of vehicle accident is also more and more frequent, causes by the people of amputation also more and more, after the amputation for the ease of work and the life, just need artificial limb is installed, especially lose lower limb in accident, the meaning that false lower limb are installed is more great.But existing false lower limb exist complex structure, Heavy Weight, install and use and safeguard all inconveniences, the defective that price is high.
The utility model content:
The purpose of this utility model is to provide a kind of false lower limb simple in structure, easy to install.
The technical solution of the utility model is as follows: it comprises support bar and sole, described support bar is connected with limbs, and play shank, it is characterized in that: frame structure is adopted in described limbs coupling part, described frame structure comprises longitudinal holding pole and horizontal ring for fixing, surround contact site with the human body deformed limb column framework that matches by described some longitudinal holding poles, be provided with in the horizontal direction the above together horizontal ring for fixing that some longitudinal holding poles is connected into integral body, bottom outside in the limbs coupling part is positioned at the mode that the position of human body knee joint rear side is connected through the hinge and is connected with the top of described support bar, and the bottom of described support bar is connected to the upper surface rear side of the sole similar to the human body sole shape.
The utlity model has simple in structure light and handy, easy to install, use flexibly, rugged road walking freely, low, the lightweight advantage of cost.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that this utility model is in the structural representation under the 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.
The specific embodiment:
As shown in Figure 1, this utility model comprises and being connected with limbs, play support bar 3 and the sole of shank effect, it is characterized in that: frame structure is adopted in described limbs coupling part, described frame structure comprises longitudinal holding pole 1 and horizontal ring for fixing 2, surround contact site with the human body deformed limb column framework that matches by described some longitudinal holding poles 1, be fixed with horizontal ring for fixing 2 on the top of longitudinal holding pole 1, middle part at some longitudinal holding poles 1 also is provided with ring for fixing, bottom outside in the limbs coupling part is positioned at the mode that the position of human body knee joint rear side is connected through the hinge and is connected with the top of described support bar 3, form the first pin joint 9, so that can rotate arbitrarily around hinged turning cylinder between limbs coupling part and the support bar 3, the bottom of described support bar 3 is connected to the upper surface rear side of the sole similar to the human body sole shape.The lower end of described support bar 3 is made as two-part, is connected through the hinge between these two sections, forms the second pin joint 10.So that sole can swing up and down around this hinge connection.
For the result of use that makes artificial limb can more meet the human body lower limbs action, the oblique elastic supporting bar 5 that is provided with between the bottom of support bar 3 epimeres and instep middle part, the two ends of described elastic supporting bar 5 are connected through the hinge respectively at the lower end of epimere support bar 3 and sole upper surface, form thus the 3rd pin joint 11 and the 4th pin joint 12; Described elastic supporting bar 5 by outer sleeve 6, be located at the spring 7 in the outer sleeve 6 and the instep support bar 8 of being located in the spring consists of, described instep support bar 8 is two, wherein an 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 is relatively unsettled setting in twos, and be provided with the gap between their opposite face, the size in gap equals or when being slightly larger than sole and being in walking states or when doing other moving type, the maximum tension stroke of elastic supporting bar 5.Described outer sleeve is made by rigid material, and described rigid material is duroplasts or the light metal material of rigidity.
Front at described limbs coupling part and support bar 3 is provided with elastic strip 14, and an end of described elastic strip 14 is connected to the front of limbs coupling part, and the other end is connected to the front of support bar 3.
In order to reduce vibrations, be provided with cushion pad 13 at the contact surface of limbs coupling part and support bar.
In order to prevent the distortion of sole, increase the intensity of sole, be provided with reinforcement at the upper surface of sole.
In order to improve the comfort level of limbs coupling part when contacting with limbs, be provided with the flexibility material at the framework inner surface of limbs contact portion.
As shown in Figure 1, more true to nature in the use procedure of walking in order to make false lower limb, the structure that the front end of sole is set to upwarp.In order to make false lower limb external form more as limbs, be coated with the support bar surrounding layer in the outside of support bar.The top of described support bar surrounding layer back is provided with breach, so that false lower limb knee joint position (being limbs coupling part and support bar junction), when the limbs coupling part is bent downwardly, can reach maximum crooked limit, the space is provided during for the bending of limbs coupling part.
