摘要： A bucket tooth assembly is mounted to an adapter provided to a distal end part of a bucket of construction equipment. The bucket assembly includes a bucket tooth and a latching member. The bucket tooth has a cavity for inserting the adapter and a through-hole that is provided to the side face and communicates through to the adapter when the bucket tooth has been mounted to the adapter. The through-hole has a center axis. The latching member is fitted inside the through-hole and having a rotational axis disposed along a direction of the center axis and a bottom part provided to an end on an adapter side in an axial direction. The latching member is rotated to switch between a first state in which the bottom part is held inside the through-hole and a second state in which the bottom part protrudes toward a concave portion on the adapter side.

摘要： A bucket tooth for a construction vehicle includes a through-hole formed in a side wall part and passing through to a cavity. The through-hole has on a cavity side a rotating body hole having a shape of a truncated and rotated cone that remains after removing a large diameter side portion obtained by cutting diagonally to a rotational axis of the truncated and rotated cone with a large diameter side of the truncated and rotated cone being disposed on the cavity side, and with the rotational axis of the truncated and rotated cone being inclined outwardly toward the distal end portion of the bucket tooth from the cavity along a width direction of the bucket tooth.
摘要翻译：用于建筑车辆的铲斗齿包括形成在侧壁部分中并通过空腔的通孔。通孔在空腔侧具有旋转体孔，该旋转体孔具有截锥形和旋转锥体的形状，在除去通过沿着具有大直径侧的截头圆锥形旋转圆锥体的旋转轴线对角切割而获得的大直径侧部分后，所述截锥形旋转锥体设置在所述空腔侧，并且所述截锥形旋转锥体的旋转轴线沿着所述铲斗齿的宽度方向从所述空腔向所述铲斗齿的前端部向外倾斜。
