Description of the invention: [Technical field of new type] This creation is a four-link brake knee joint, which uses the body weight or the reaction force of the prosthetic heel to touch the ground to reduce the gap setting of the beam to limit the axis rotation. Avoid prosthetic knee joints that are dangerous to stand for easy standing or bending. • [Prior Art] A good prosthetic knee joint can provide different center of gravity and corresponding cushioning in different gait cycles or standing states. At the same time, the prosthetic knee joint should be properly set during the bending process of walking or center of gravity change. Safety structure to prevent sudden bending and cause danger. As shown in the seventh figure, the prosthetic user does not bend and stand in the knee joint. 'Double talk can usually support the body weight stably. With the extension of the standing time, it also needs to be adjusted by the slight curvature of the knee joint or the change of the center of gravity. To ease the posture to relieve the pressure on the local joints; as shown in Figure 8, the four-link prosthetic knee joint, in the unbent standing state, can stabilize the weight of the branch body, but if the center of gravity is from the healthy limb When the side is turned to the prosthetic side, it is easy to make the knee joint suddenly bend in a clockwise direction and cause danger; the sudden bending is as shown in the ninth and tenth pictures. 'When the prosthetic user walks on a flat or downhill road surface 'The prosthetic heel hits the ground and will produce upward force from the sole of the foot. At this time, if the weight is turned to the prosthetic side, it will easily cause the knee joint to bend clockwise in the direction of 201235022, causing the risk of falling. Therefore, the four-link prosthetic knee is used. There is still room for further improvement in the joints. [Description of the Invention] The present invention is a four-link brake knee joint, the knee bearing is provided with a front perforation and a rear perforation. The inner side of the knee bearing is provided with an inner connecting rod's connection buffer assembly; the Ou Bo body is provided with a frontal opal. The body is perforated, and the rear part is provided with a pressure block; the second symmetric first cup is connected to the knee socket before the upper end of the perforation is connected with the perforation of the opal body; the second symmetric second link is connected with the upper end of the knee bearing; The sinusitis is disposed on the inner side of the first link and the inner side of the second link. The lower end of the upper perforation is provided with a lower perforation, and the upper perforation is connected to the lower end of the second link by a shaft, and the lower perforation corresponds to the lower end. The perforation of the cypress body, the rear end of the bundle clip contacts the pressure block behind the cypress body; the upper perforation is provided with a gap 'the gap is provided with more than one singularity' and extends from the upper perforation downward to the bottom of the bundle clamp, and the gap opening is located The lower perforation and the rear end of the bundle clip. In view of the above-mentioned defects in the use of the four-link prosthetic knee joint, the creation is mainly in the four-link structure of the prosthetic limb, and a bundle of clips is set; when the prosthetic user adopts a knee-bending easy posture or changes the center of gravity to the prosthetic side When the weight of the body is matched with the upward force of the lower end of the prosthesis, the pressure block behind the Ou Bo body can directly press the rear end of the bundle clamp. At this time, the gap placed in the bundle clamp will shrink and clamp the shaft to stop the rotation; When the user walks on a flat or downhill road, he can also use the prosthetic heel to create an upward force on the ground, so that the Opal body 201235022 can also clamp the axis to stop bending in the clockwise direction, resulting in the rear clamp directly. Press the back end of the bundle clip and turn 'to avoid the risk of the prosthetic knee suddenly falling. [Embodiment] The following is a detailed description of the structure and function of this creation, with the preferred embodiment, with the detailed description of the drawing &, to increase the understanding of this creation; this creation is a four-link brake knee joint 'please refer to the first As shown in the figure of the figure, the main components include the knee bearing 1, the first link 2, the second link 3, the clamp 4 and the opal body 5, wherein; see the first figure to the sixth figure. As shown, the knee bearing (1) is provided with a front (4) and a rear perforation 12, the upper part can be connected to the prosthetic barrel, and the inner side is provided with an inner connecting rod 丨3 to connect the buffer assembly 14; an opal body 5 with a perforated body in front a pressing block 44 is arranged at the rear, and the pressing block 44 can adjust the protruding amount; the second symmetric first connecting rod 2; the upper end is connected to the perforation 11 before the knee bearing seat 1, and the lower end is connected with the perforation of the opal body; a connecting rod 3, the upper end is connected to the perforation 12 after the knee bearing 1; a bundle of clips 4 is disposed inside the first connecting rod 2 and the second connecting rod 3, the upper end is provided with an upper perforation 41, and the lower lower end is provided with a lower perforation 4 2, the upper perforation 41 is connected to the lower end of the second link 3 by the axial center 45, and the lower perforation 42 corresponds to the perforation of the opal body, the bundle 4 The end is in contact with the pressing block 44; the upper perforation 41 is provided with a gap 40, the gap 40 is provided with more than one bending section 401 ' and extends downward from the upper perforation 41 to the bottom of the bundle 4; the gap opening is located in the lower perforation 42 and the bundle Between the clip rear ends 43. 201235022 Please refer to the second figure to the sixth figure. The four-link brake knee joint of this creation mainly uses the body weight or the reaction force of the prosthetic heel to touch the ground to reduce the gap 40 set by the bundle clamp 4 to limit the axis. The heart 45 rotates; maintaining the same standing position for a long time is likely to cause local joint burden or muscle fatigue. Therefore, when the prosthetic user needs to take a knee-bending easy posture or change the center of gravity to the prosthetic side, the beam can be used. 4, with the body weight combined with the lower end of the prosthetic force 'the pressure block 44 behind the opal body 5 directly presses the rear end 43 of the bundle clamp, the gap 40 disposed in the bundle clamp 4 will shrink and clamp the axis 45 , so that it stops rotating, like the state of easy standing in the second figure; and when the prosthetic user walks on a flat or downhill road, as shown in the third and fifth figures, the prosthetic heel does not touch the ground. Therefore, the gap between the bundle clips 4 is larger, so that the shaft 45 can be freely rotated to complete a smooth kicking motion; when the prosthetic heel is in the state of the fourth and sixth figures, the prosthetic heel can be used. Produced by the land The upper force causes the pressure block 44 behind the Ou Bo body 5 to directly press the rear end of the bundle clamp 4 to narrow the gap 40, and clamp the shaft 45 to stop the rotation, thereby preventing the prosthetic knee joint from suddenly bending in a clockwise direction and causing a fall. The dangers mentioned; however, the above-mentioned ones are only the target examples of the creation of this creation, which can not be used as a limit to the implementation of this creation, w, 丄固凡依本The scope of the patent application
