Description

真空吸附式扭转避震接头
技术领域
本发明是有关于一种真空吸附式扭转避震接头，指一种利用单向阀设置的密封件与活塞，配合枢接件对应承载座进行上下移位时，能将气体通过上气室与下气室间形成真空进行排出，并辅以扭转弹簧与扭转强度调整螺丝加以限制该活塞的旋转角度，让使用者得以获取更佳的避震体验。
背景技术
避震结构于义肢关节上的应用，随医学发达在医疗实务及技术上日益精进，为一种相当常见且普遍的设计，然而，各家厂商都为了让使用者能体验更加舒适的穿戴感受，而努力不懈的进行改良与创新。
请参阅美国专利US7744653，所揭示的一种用于假肢装置的具有减震和受控旋转的真空泵，利用壳体配合轴形成泵室或真空室和减震室，该轴的往复运动将会引其活塞在真空室内的往返运动，当活塞在真空室内进行向上行程时，真空室内的空气将会通过排气阀排出；而当活塞向下行程时，空气会从连接的承窝藉形成真空进行减压的目的；当中另提及的一旋转结构由一对设置于该抵座内径中的滑块，对应一安装狭槽来限制滑块的有限范围运动，该滑块为具弹性材质所构成，且利用一轴触头配合轴心旋转时，将会推抵该滑块产生压缩并变形，从而完成旋转的目标。
然而，前述用于假肢装置的具有减震和受控旋转的真空泵，其整体虽有多个气室能配合使用，但只有一个真空室有实质上进行真空缓冲的效用；而关于旋转结构的设计，其相关的构件数量及安装方式都过于复杂，也将使得后续维护检修不易。
再请参阅美国专利US6645253，所揭示的一种用于假肢装置的真空泵和减震器，其中结构配合说明书的图22-25所示，汽缸220上方形成第二腔室250、而该汽缸220下方形成第二腔室240，而该第二腔室240下方另设有一第三腔室241，开始状态的第二腔室250呈最大容积，而第一阀装置270关闭让套筒中的腔62呈密封状；当壳体210带动活塞260同时向下位移时，该第二腔室250缩小容积，使空气通过第二阀装置280离开，同时，也让第二腔室240通过进/排气口272至腔62，且通过第三腔室241内的空气提供减震功能；当持续向下位移后，第一腔室240将呈最大容积，而第二腔室250则呈最小容积；依靠循环，得以通过不同于各腔室的通道进行空气导引流通，来达成缓冲及真空导引目的，让使用者的行走体验更加舒适。
然而，前述假肢装置的真空泵和减震器，在于空气导引均通过进/排气口272进行流入与排出，此种结构将让信道需额外配置相关阀口设计才得以共同使用同条通道，因此，也让通道更加复杂，而相关连接的腔室数量也就难以减少，且当用户行走速度有所提高或降低时，将影响到空气导引的流畅性，而导致使用者行走感触受到影响，因此，仍存有许多待改善的缺陷。

具体实施方式
下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
参照图1-5，本发明为一种真空吸附扭转避震接头，其包含有：一承载座10，具有一容室11及一排气孔101，该容室11下方设置有一缓冲组件12，且该缓冲组件12包含有：一缓冲壳体121、一轴杆限位座122、一弹性组件22及一缓冲强度调整螺丝124，该缓冲壳体121内由上至下供轴杆限位座122与弹性组件123置入后，再以缓冲强度调整螺丝124配合缓冲壳体121底部封闭，而前述弹性组件123为一种弹簧，亦能替换为同样具备弹性材质，并不加以限制。
一限位组件20，包含有：一定位轴21、一密封件22，该定位轴21下端穿设承载座10连接缓冲组件12，而密封件22则连接定位轴21上端；一枢接件30，具有一进气孔301、一嵌槽31及一穿孔33，该嵌槽31配合一活塞32封闭于枢接件30内，而穿孔33则供一轴杆40经该定位轴21内部穿设连接该轴杆限位座122，供缓冲枢接件30承受的压力，且该进气孔301内更设置有一进气孔单向阀302，能用以限制上气室50内的气体F逆向流出。
前述密封件22上方配合枢接件30形成有一上气室50，而活塞32配合密封件22下方则形成一下气室60，当枢接件30位移向上时，该进气孔301导引套筒内气体F流至上气室50形成真空，而下气室60则配合该排气孔101排出；当枢接件30位移向下时，则上气室50气体F流至该下气室60形成真空，使枢接件30能在承载座10内稳定运作。
前述容室11内，更设有两扭转弹簧111与两扭转强度调整螺丝112，该扭转弹簧111穿置于容室11内，且扭转弹簧111分别各自具有一第一端1111及一第二端1112，该活塞32上方设有数个固定螺丝322，此固定螺丝322主要用于固定该枢接件30用，通过调节该扭转强度调整螺丝112顶抵第一端1111与第二端1112的弹力强弱，则能进一步限制枢接件30左、右旋转的角度，而该枢接件30于本实施例中的旋转角度为顺、逆时针方向15度左右，此旋转范围能依前述扭转弹簧111所提供的弹力强弱加以配合调整，属于本领域具一般技术知识水平者都能轻易实施的。
其前述密封件22的表面穿孔处，更设置有一密封件单向阀221，主要能让由进气孔301进入的气体F，能由上气室50单向进入该下气室60，防止逆流情况发生；且另于该活塞32的表面穿孔处，也设置有一活塞单向阀321，也是让下气室60中的气体F能单向通过该排气孔101，使气体F得以顺利排出至外部。
本发明一种真空吸附扭转避震接头，再请参阅如图6-7所示，当中的扭转弹簧111能改为环状设置，并配合扭转强度调整螺丝112让该枢接件30旋转角度的结构受到限制，此结构仅有部分更动，且属本领域简易的更动设计，故不再多言赘述。
综上所述，本发明真空吸附式扭转避震接头，通过承载座10配合枢接件30所形成的上气室50与下气室60，能对应使用者的步行动作位移，通过该枢接件30内的第一活塞22和第二活塞32的单向流通设计，使套筒内气体F单向进入上气室50与下气室60时，能形成真空进行排气作用，且更利用容室11内的扭转弹簧111与扭转强度调整螺丝112的相互顶抵，使枢接件30与承载座10之间得以进行扭转角度的调整。
以上依据图式所示的实施例详细说明了本发明的构造、特征及作用效果，以上所述仅为本发明的较佳实施例，但本发明不以图面所示限定实施范围，凡是依照本发明的构想所作的改变，或修改为等同变化的等效实施例，仍未超出说明书与图示所涵盖的精神时，均应在本发明的保护范围内。

其特征在于：所述密封件(22)上方配合所述枢接件(30)形成一上气室(50)，所述活塞(32)配合所述密封件(22)下方形成一下气室(60)，当所述枢接件(30)向上移位，所述进气孔(301)导引套筒内气体流至所述上气室(50)形成真空，所述下气室(60)则配合所述排气孔(101)排出；所述枢接件(30)向下移位，则所述上气室(50)气体流至所述下气室(60)形成真空，使所述枢接件(30)能在所述承载座(10)内稳定运作。
2.根据权利要求1所述的真空吸附式扭转避震接头，其特征在于：所述容室(11)还包含有：两扭转弹簧(111)和两扭转强度调整螺丝(112)，所述扭转弹簧(111)穿置于所述容室(11)内，且所述扭转弹簧(111)各具有一第一端(1111)及一第二端(1112)，所述活塞(32)上方设有数个固定螺丝(322)，通过调节所述扭转强度调整螺丝(112)顶抵所述第一端(1111)与所述第二端(1112)的强弱，以限制所述枢接件(30)左、右旋转的角度。
3.根据权利要求1所述的真空吸附式扭转避震接头，其特征在于：所述进气孔(301)还包含有：一进气口单向阀(302)，以限制所述上气室(50)内的所述气体逆向流出。
4.根据权利要求1所述的真空吸附式扭转避震接头，其特征在于：所述密封件(22)还包含有：一密封件单向阀(221)，设置于所述密封件(22)的表面穿孔处，使所述进气孔(301)进入的气体能由所述上气室(50)单向进入所述下气室(60)内。
5.根据权利要求1所述的真空吸附式扭转避震接头，其特征在于：所述活塞(32)还包含有：一活塞单向阀(321)，设置于所述活塞(32)的表面穿孔处，使下气室(60)的气体单向通过所述排气孔(101)。
6.根据权利要求1所述的真空吸附式扭转避震接头，其特征在于：所述枢接件(30)旋转的角度为15度。
