Less than the upper cushioning force of the cushioning device 53, the second rod group of the linked rod group 6Q does not move much downwards, so it will not hit the blocking body protruding from the top section of the third group with a groove 743. Backward tilting & β 77 has no effect. 'At this time, the down pressure will move the middle g group 8 through the actuator group W, and the elastic element is pushed down by the top ring 521 to make the first elastic buffer. In addition, a r Let's consider Fig. 5. When the hollow tube group 8 moves down, the interval between the hydraulic pressure and the hydraulic pressure is between 1 and 1; a. The clothes 81 are also shifted downward, and then the space under the hydraulic cylinder 83 is compressed, so that the oil can only be tilted. Road 746 μ μ λ ^ 仃 遑 Mb machine passes through a set of grooves 741 and passes through the mouth 7410 'to lift off the ball 750 to press the elastic element 751, via the ramp 744, M280211 enters Yitun oil storage road 73 and then from the ramp 745 tried to return to the lower oil pressure rainbow 83 through the upper j of the second set of grooves 742: Yikou 7420, the lower core pushed away from the upper ball yang and pressed the elastic element ⑽, but because At the same time, the oil pressure 83 is also trying to balance the upper and lower balls 763 'of the ramp 747, so the oil cannot flow, forcing the oil to pass through the annular oil storage channel 73, ramp 748, through groove, ramp 749. Enter the hydraulic cylinder 82 to make a second buffer, so that the prosthetic wearer is quite i: ® When the force / shaw is lost, the hollow tube group 8 is pushed back to the original position by the elastic release of the elastic element 522. Straight, at this time, the spacer ring 81 is also displaced upward, pressing the oil of the oil pressure cylinder 82 from the ramp 749, the through groove m, the ramp ⑽, the ring-shaped oil storage channel 73, and then the ramp 745 through the first: set the groove The upper mouth of the cymbal is measured, and the top of the lower cymbal is pushed away from the upper ball 763 to press the elastic element pressing cylinder 83. 764 while returning to the bottom of the oil, from the above explanation, we can know that the anti-backward control flow of the two groups of grooves 743 is set up. The main dimension of the oil tank 82 is a normal knee and straightening. The oil passage of the lower hydraulic cylinder 83. BI (Although Xi Ge 丨 In the case of early depression of the center of gravity momentarily, the downward force transmitted to the cushioning device 53 will be greater than the top cushioning force of the cushioning device 53. The second rod group 6 of the linkage rod group 60gi Underneath, the top to the resistance body Chuan protruding from the third set of grooved tops 772 ball 773, the resistance body 77] moves downwards and covers the upper ramp m, so that the path of the upper _⑽__ 774 is Blocking, # 卜 仏 tired, the communication between the oil pressure cylinder 82 and the annular oil storage channel 73 is blocked, which means that the main dimension of the communication path between the oil 82 and the oil lowering red is blocked, and the flow regulation of the oil circuit is blocked. The mechanism was stopped. Even though the hollow pipe was still under test, the oil M12211 could not flow at all because of the oil correction and the oil pressure of Hung Hom, so that the hollow pipe group 8 could not be displaced downwards. The disabled person is provided with a support instantly, so it will not fall over, which is quite safe, until the downforce of the 601-rod group is released. Referring to FIG. 3 again, when the rotation group is set on the first set of grooves 741 隘 7410 The displacement of the plug body of the curved oil path controller 75 is used to make a small adjustment of the area of the cover 744 to control the oil flow.胄 m The amount of circulation means that the softness and stiffness of the knee can be controlled. Similarly, when the rotation group is located in the second group, the slot 742 P Yikou 7420 is used to block the block 76 of the straight oil controller 76. Displacement Adjust the small area of the ramp to control the flow of oil in the ramp 745, which means that the softness of the straightening can be controlled. Referring to FIG. 4, the hollow tube group 8 The oil is injected into the upper oil pressure cylinder 82 and the lower oil pressure cylinder 83. The operation is to open the closed body 8G2 and inject oil. The lower oil chamber 845 and the second one-way controller 86 in the industrial and industrial channels flow to the upper storage. The oil reaches 844 ', the first one-way controller 85 flows to the upper volume chamber 841 in one direction, enters the oil pressure cylinder 82 through the channel 843, the chute 749, and the groove 748 enters the ring $ storage channel 73, as shown in Figure 5, Then, the ramp m passes through the upper recess 742 () and the lower recess 742 of the second and σ groove 742 to press the elastic element m away from the upper ball to flow to the lower oil magic tank 83. After all the oil is filled, There is a resistance to stop the oil filling and seal the closed body. At this time, the lower oil chamber, the upper oil storage chamber 844, upper, and τί are tired of soil. The oil pressure red 82 even reaches the lower oil pressure. 83, that is, the pressure of all oil filling parts is equal. Β Tian Ren / by the pressure of the oil in the cylinder is consumed, it will cause the upper tank of the upper oil storage room 844 to be high in the oil migration &82; The oil is automatically replenished from the lower oil chamber 845, the second one-way controller 86, the upper oil storage chamber, and the first one-way controller 13 M280211 to the oil pressure cylinder 82 to achieve a pressure balance. When the oil is used, it is necessary to inject new oil from the outside into the hollow pipe group 8. / In summary, this case can indeed achieve the protection of the knee joint momentary _ backward tilt by blocking the oil circuit. It is only an enhanced embodiment of the new model. When the scope of implementation of the new model cannot be limited by this, that is, any simple equivalent changes and modifications made according to the scope of the patent application of the new model and the content of the new specification should still belong to the new model Within the scope of the patent.
