Abstract: A key assembly is press fit into an annular space between a box and pin member to resist relative rotation of the box and pin members. The key assembly includes wedge like members that contact one another along complementary tapered surfaces, and when in contact generate radial forces into the box and pin member to secure the connection between the box and pin. The outer wedge is inserted first into the annular space between the box and pin members, and has rows of elongate teeth that project radially outward into contact with an inner surface of the box member. Because the outer wedge is pushed radially outward against the box member rather than axially sliding therebetween, the teeth protrude into the surface of the box member thereby increasing the anti-rotation force created by the outer wedge.

Abstract: A pipe connection includes a pin having external threads and a box having internal threads. A circumferentially extending row of pin teeth are located on an exterior portion of the pin. A slot extends through a side wall of the box. A key is carried in the slot, the key having a row of key teeth that mate with the box teeth. The key is mounted to the box such that a movable portion of the key is radially movable relative to the box between radially outward and radially inward positions. The key is biased toward the inward position, so that the key teeth ratchet on the pin teeth during make-up of pin and the box. The teeth have a saw-tooth configuration to resist unscrewing rotation of pin and the box. The key may be an integral part of the side wall of the box or a separate component.

Abstract translation: 管道连接包括具有外螺纹的销和具有内螺纹的箱。 一个周向延伸的销齿排位于销的外部部分上。 插槽延伸穿过盒子的侧壁。 钥匙在槽中被携带，钥匙具有与盒齿匹配的一排关键齿。 钥匙被安装到盒子上，使得钥匙的可移动部分在径向向外和径向向内的位置之间相对于盒可径向移动。 钥匙偏向向内的位置，使得钥匙齿在销钉和盒子组装时在销齿上棘轮。 齿具有锯齿结构，可抵抗销和箱的旋转旋转。 钥匙可以是箱子的侧壁或单独的部件的组成部分。

Abstract translation: 键组件压配合到盒和销构件之间的环形空间中以抵抗盒和销构件的相对旋转。 钥匙组件包括楔形构件，楔形构件沿着互补的锥形表面彼此接触，并且当接触时产生径向力进入箱体和销构件以固定箱体和销之间的连接。 外楔子首先插入到盒和销构件之间的环形空间中，并且具有一排细长的齿，其径向向外突出地与盒构件的内表面接触。 因为外楔形物被推向径向向外抵靠盒构件，而不是在其间轴向滑动，所以齿突出到箱构件的表面中，从而增加由外楔产生的抗旋转力。
