Description
Technical field
This utility model relates to a kind of off normal adjusting device, relates in particular to a kind of artifucial limb off normal adjusting device.
Background technology
In some cases, for example unexpected injury, health problem, born incompleteness etc. make people need install artifucial limb.With reference to Figure 7 shows that a kind of typical artifucial limb assembly.It includes an adapter A, and this adapter A has a centrage A1, and a body of rod B, and it has a stacker B1 and a centrage B2.Because of the relation of planform, adapter A often can't just be positioned to hold the centrage C1 of a C, therefore works as stacker B1 and is linked to adapter A, and the centrage B2 of body of rod B can't align and hold a C centrage C1.If body of rod B centrage B2 departs from and holds a C centrage C1, can cause the centre of body weight of artifucial limb wearer to depart from.Hold a B1 because of adapter A is fixed in again, the artifucial limb wearer can't be adjusted the position of adapter A according to centre of body weight, dress a period of time after, not only can cause abnormal gait, and can feel muscle sprain and muscle fatigue.
With reference to figure 8 and Fig. 9, for showing a kind of artifucial limb structure of the prior art with off normal correcting unit.It includes one first member D and one second member E, and this first member D has a centrage D1 and an opening D2, all offers a screwed hole D3 at the four direction of its sidewall.This second member E is formed in one, and includes a dome E1 in conjunction with a connection piece E2, and the top of body E3 is in conjunction with a taperer E4.The taperer E4 of the second member E can place in the first member D opening D2, and can in opening D2, do the action of front, rear, left and right translation and rotation, with after centrage E5 that adjusts the second member E and the centrage C1 overlapping of holding a C, be screwed together in screw hole D3 respectively by four screw F again, and then the surface of supporting the taperer E4 that pulls makes its second member E and holds a C and fixes.As stacker B1 and connector E2 binding, the centrage C1 that the centrage B2 of body of rod B just can align and hold a C.
Though the body of rod B that above-mentioned off normal correcting unit of the prior art can solve traditional artifucial limb assembly with hold the problem that a C can't align, but finding in actual use has two significant problems on the safety: first significant problem is, because the taperer E4 size of the second member E is much smaller than the opening D2 of the first member D, after the second member E is with respect to opening D2 off normal, from taperer E4 screw hole D3 far away, its inner screw F must stretch out longer, can support the taperer E4 surface of pulling, so easily cause the contact surface of screw F and screw hole D3 to significantly reduce, so off normal of skidding easily, make screw F end face can't be butted on the situation on taperer E4 surface (shown in Fig. 9 A) really, and then cause the second member E loosening, even the centrage B2 that reproduces into body of rod B can't align and holds the problem of C centrage C1.Second significant problem is, in case taperer E4 is adjusted to the position (shown in Fig. 9 B) in corner, this moment, the contact surface of all screw F and taperer E4 was minimum, also be that taperer E4 is also minimum by the fixed contact amount of screw F, be easy to cause taperer E4 to produce rotation or loosening phenomenon under this state, user is fallen easily.
Summary of the invention
