Abstract

The utility model relates to an improved knee joint, which is mainly characterized in that a rotary part is sheathed in a knee joint body through a shaft center and is driven to rotate by using the shaft center as a center. A unidirectional bearing is arranged in a rotary device of the rotary part, so that the rotary part can be quickly restored counterclockwise with the help of the restoring force of a cushioning device and the unidirectional bearing of the rotary part, and can be slowly bent clockwise with the help of the cushioning device and larger friction force. With the to-and-fro movement of the rotary part, disabled people can effectively use an artificial limb to move more conveniently.

请参阅图1、2,本实用新型是利用轴心3000将旋转部2000套接于膝郑节主体1000内,让旋转部2000以轴心3000为中心旋转,于膝关节主体1000下方设有一枢接套筒1100,要将支杆6000固定,其支杆6000下方可枢接上脚踝和脚掌等结构;于枢接套筒1100上方设有一穿孔1010,利用插销5200可将缓冲装置5000结合在膝关节主体1000下方,使缓冲装置5000以插销5200为中心旋转使用,其缓冲装置5000上端的穿孔5010,可与旋转装置2100后端的插销5300通过穿孔2110连接,达到当旋转部2000以顺时针旋转时,利用缓冲装置5000可缓慢的弯曲,不易快速弯曲而产生不平衡,使残疾人士发生危险;其膝关节主体1000上方亦安装一弹性橡胶5100,可吸收旋转部2000转回时的冲击力量。 Referring to FIG. 1, the present invention is the rotation portion 3000 by using the knee axis 2000 in the socket main body section Zheng 1000, 2000 so that the rotating portion 3000 is rotated about the axis, below the knee joint body is provided with a pivot 1000 then the sleeve 1100, to fixing struts 6000, 6000 before its pole connected to the ankle and foot pivot like structure; above the pivot sleeve 1100 is provided with a through hole 1010, a latch 5200 may use the buffer device 5000 incorporated in the knee beneath the joint body 1000, the buffer device 5000 to use the plug 5200 is rotated, perforation 50105000 upper cushioning means may be connected with the latch 2110 53002100 rear rotating device through the perforations, when the rotating portion 2000 to achieve a clockwise , by the buffer device 5000 is bent slowly, a lack of rapid bending unbalanced, so that the risk of people with disabilities; 1000 above its knee joint body is also mounted a resilient rubber 5100, can absorb an impact force during rotation back portion 2000.

于残疾人士的大腿上加装一枢接部6100,将上盖4000和枢接部6100结合,其上盖4000利用插销5400要与旋转装置2100的穿孔2130结合,使移动时以轴心3000为中心弯曲使用。 When installed on a thigh of the disabled pivot portion 6100, the cover 4000 and 6100 in conjunction with pivoting portion, which cover the use of 4000 to 2130 latch 5400 in conjunction with perforation of the rotating means 2100, 3000 as the moving axis in bending center use.

其旋转部2000是将旋转装置2100内加装有一间隙2220的一套筒2200和一单向轴承2300,该套筒2200内表面为一磨擦面2210,该单向轴承2300外面为一旋转面2310,该旋转装置2100上方设有一孔口2120,该孔口2120内设一压键2600,于旋转装置2100两旁各安装一档板2400、2500,将轴心3000和旋转部2000利用螺丝3100锁固于膝关节主体1000上,以轴心3000为旋转中心旋转运用,其档板2400、2500内分别设有轴承2410、2510,可使旋转部2000以轴心3000旋转更为顺畅,加上缓冲装置5000上方与旋转装置2100连结处的穿孔5010亦设有一轴承5020,也可使旋转更为顺畅。 The rotation unit 2000 is installed within the rotary device 2100 has a gap of a sleeve 2220 2200 2300 and a one-way bearing, the inner surface 2200 of the sleeve is a friction surface 2210, 2300 outside of the one-way bearing to a rotation plane 2310 , above the rotary device 2100 is provided with an opening 2120, the aperture 2120 a pressed key features 2600, 2100 on both sides of each mounting a rotating means 2400,2500 baffles, and rotation of the axial portion 3100 30,002,000 fastening by screws body on the knee 1000 to 3000 as the rotation center axis use, are provided with baffles in its bearings 2410,2510 2400,2500, 2000 can more smoothly rotating about the axis of rotation section 3000, with the damping device 50102100 perforation at the junction of 5000 and above the rotating means also has a bearing 5020, also allows smoother rotation.

请参阅图3、4所示,本实用新型其上盖4000以轴心3000旋转至缓冲装置5000无法再缓冲时,其缓冲装置5000亦可减缓弯曲时的速度;于上盖4000内设有一螺丝4100,利用螺丝4100可调整压杆4200的位置,藉由位置变动可调整施力的大小。 Please refer to FIG. 3 and 4, the present invention is that when the cover 4000 to the rotation axis 3000 to the buffer device 5000 is no longer a buffer, which buffer device 5000 may slow down during bending; cover 4000 in a screw-site 4100, 4100 by screws 4200 to adjust the position of the lever, by biasing the position variation resizable.

请参阅图5、6所示,本实用新型其单向轴承2300只允许逆时针旋转,所以当旋转部2000以逆时针旋转时该单向轴承2300才能发挥功能而能快速的旋转,当旋转部2000以顺时针旋转时因单向轴承2300不能使用,所以旋转时将带动单向轴承2300,变成以单向轴承2300的旋转面2310旋转,且因旋转面2310在套筒2200的磨擦面2210内旋转,将导致磨擦面积变大,达到逆时针旋转时快速,而顺时针旋转时缓慢的运动方式,使残疾人士更方便使用;其旋转装置2100上方设有一孔口2120,于孔口2120内设有一压键2600,当压键2600受力后将压迫套筒2200使间隙2220变小,造成旋转面2310和磨擦面2210的磨擦力变大,就如同煞车功能而无法旋转,故只需较小的压力即可停止旋转,除了无法于压键2600上施力的角度外,超过30度还可停止旋转,可让残疾人士更为安全。 Please refer to FIG. 5, 6, the present invention which allows only one-way bearing 2300 is rotated counterclockwise, the rotating portion 2000 so that when the counterclockwise rotation of the one-way bearing 2300 can play a function capable of rapid rotation, when the rotating portion 2000 clockwise rotation due to the one-way bearing 2300 can not be used, it will drive the one-way bearing rotates 2300, 2310 into rotation to rotate one-way bearing surface 2300, and 2310 due to the friction surface of the rotating surface of the sleeve 2200 2210 the rotation, will cause large friction area, achieve rapid counterclockwise rotation, rotates clockwise during a slow motion, making it easier to use the disabled; thereabove rotating means is provided with an opening 2100 2120, 2120 within the aperture 2600 is provided with a press button, when pressed key will force compression sleeve 2600 2200 2220 gap becomes smaller, resulting in the rotation plane friction surfaces 2310 and 2210 increases friction, like braking function can not rotate, only more so little pressure to stop the rotation, in addition to not force the pressure on the key 2600 point of view, but also stops rotating more than 30 degrees, so that people with disabilities can be more secure.

综上所述,其所揭露的改进的膝关节,不仅安全且更方便使用,运用时其增进的功效更已具先进性及实用性的专利要件;但以上所述,仅为本实用新型的一较佳实施范例,当不能以之作为限定本实用新型实施的范围,凡依本实用新型申请专利范围所作的均等变化或修饰,仍应属本实用新型专利涵盖的范围内。 In summary, improved their knee to expose not only safe and more convenient to use, enhancing its effectiveness has been more advanced and practical elements when the patent application; but above Although the present invention a preferred exemplary embodiment, when it can not be defined as an embodiment of the present invention range, is apparent to all equivalent changes or modifications made to a range of new patent, it should remain with the scope of the invention covered by the patent.
