Description

管子转接器
本发明涉及一种用于和模件式假体的管件端部夹紧连接的管子转接器。
这类结构形式可由美国专利文件3659294中得知。尤其可由图3和4看出，调整芯棒的凸台设计为4棱锥体，该锥体的顶垂线恰好穿过球拱的球心。在联接位置，此凸台穿过转接器构件的环状球窝，一直插到固定螺钉所在部位，每一个棱锥体面上拧紧一个螺钉，螺钉大体重直于此棱锥面，因此，螺钉轴线与管子横剖面构成锐角。
固定螺钉将转接器构件与调整芯棒联接起来。但与此同时，固定螺钉还用来调整此调整芯棒的中轴线相对于管件轴线的位置。通过松开一个螺钉以及再拧紧与此相对的那个螺钉，可以使调整芯棒相对于管子转接器在一个规定的平面内摆动。通过类似地调整另外两个互相对置的夹紧螺钉，可使芯棒在垂直于第一个平面的第二个平面内进行摆动，此时，调整芯棒的球拱在转接器构件的环状球窝中滑动。
管子转接器一般用钢或钛制造，而管件用铝制成。在这种已知的结构形式中，管件的两端各插入一个管子转接器内，其中，它们之间的连接可采用压配合，或也可设计为夹紧连接。在后面那种情况下，管子转接器设有一个夹箍，可用螺栓将夹箍收紧。
本发明的目的在于提出一种改进管子转接器与管件之间连接的管子转接器。
本发明的目的是这样实现的，即提供一种管子转接器，它由一个轴向开缝并可用夹紧螺栓或类似物周向夹紧的连接套管构成，连接套管用于安装管端，在其一端连接着一个环状的联接段，联接段圆周上最好有4个沿圆周彼此等距的螺纹孔，用于各装入一个联接和调整螺钉(固定螺钉)，联接段端面有一个环状球窝，用于与一根调整芯棒的球拱相靠，在联接状态，此调整芯棒以其设计为多面棱锥体的凸台插入联接段，直至固定螺钉所在的夹紧区，并且在与联接段相对的连接套管的自由端段的内环面上，设有一个塑料夹紧环。
本发明以下列认知为基础：由于夹紧，正好使管件在因假体载荷造成最高应力的部位加载。此外，已经确定，对于已有的那些结构形式，每一次的负荷变换均会导致连接套管与管件之间的相对运动，从而会损坏铝制管件。
与之相对，按本发明，夹紧不再直接在管端进行，而是离开管端一定距离，所以，在塑料夹紧垫与连接段之间的管段可以承受弹性变形。在连接套管与管端之间相对运动最大的区域内，由于此塑料夹紧环而防止了这两个构件间的金属摩擦。动态的弯曲试验结果证实，这一改进大大延长了上述构件的使用寿命。
附图表示了作为举例用的本发明实施例。其中：
图1是管子转接器侧视图；
图2是用放大比例表示图1所示管子转接器和一段插入其中的管件的纵剖面。
图中表示了管子转接器1，它由一个连接套管2和一个连接在其一端的环状联接段3组成。由图2可以看出，连接套管2用于安装插入管端4。
在联接段3的圆周上有4个沿圆周彼此等距的螺纹孔5，用于各装入一个图中未进一步表示的联接和调整螺钉(固定螺钉)，在联接段3的端面，有一个环状球窝6，用于与图中未进一步表示的一根调整芯棒的球拱相靠，在联接状态，此调整芯棒以其一个设计为多面棱锥体的凸台插入联接段3中，直至固定螺钉所在的部位。
在与联接段3相对的连接套管2的那一端设有端段7，此端段7包含着一个塑料夹紧环8，后者嵌入端段7的一个环槽9中。塑料夹紧环8可松动地置入环槽9中。选择塑料夹紧轴环8和环槽9的尺寸，应在连接套管2的整个轴向长度上产生夹紧作用，但主要应在塑料夹紧环8的轴向长度上产生夹紧作用。另外，夹紧环也可以不是一个单独的环，而用连接套管2内部的涂层来代替。夹紧环8的轴向长度最好约为连接套管2的轴向长度的五分之一。
连接套管2上开有一个轴向缝10，缝的末端设卸荷孔11。连接套管2在轴向缝10的两侧各设有一个凸块12，在这两个凸块12上各制有一个孔13，这两个孔13相互同心，用于装入一个图中没有进一步表示的夹紧螺栓。
