The invention discloses an inner expansion connection device. An expansion shell, a seal cover, an expansion connecting pin and a wedged piece are included. The expansion shell is provided with a through groove penetrating through the two ends. The through groove comprises a stretching-in section and a clamping connection section, and the inner diameter of the clamping connection section is largerthan that of the stretching-in section. The seal cover is arranged at the end, corresponding to the clamping connection section, of the exterior of the expansion shell. The expansion connecting pin comprises a connection section and an expansion section. The expansion section is provided with an expansion groove. The expansion groove axially extends in the connection section direction from the end portion of the expansion section. The expansion groove divides the expansion section into at least two parts, and the expansion section stretches into the expansion shell. The wedged piece comprisesa head part and a tail part, the outer surface of the wedged piece is gradually inwards folded from the head part to the tail part, and the wedged piece stretches into the expansion section from thetail part along the expansion groove so that the expansion section can be expanded. The inner expansion connection device is simple in structure and low in cost, connection is more reliable, and usageis more convenient.
本发明公开了一种内膨胀连接装置，包括：膨胀壳，其具有贯穿两端的通槽，通槽包括伸入段和卡接段，所述卡接段的内径大于伸入段的内径；封盖，其设置于膨胀壳外对应卡接段的一端；膨胀连接销，包括连接段和膨胀段，膨胀段上设置有膨胀槽，膨胀槽由膨胀段的端部向连接段方向轴向延伸，膨胀槽将膨胀段分割成至少两部分，所述膨胀段伸入膨胀壳内；楔形件，包括头部和尾部，其外表面由头部至尾部逐渐向内收拢，楔形件由尾部沿膨胀槽伸入膨胀段将膨胀段涨开，本发明结构简单，成本低，但连接更加可靠，使用更加方便。
