Quick connecting assembly and connecting device
The invention provides a quick connecting assembly and a connecting device. The quick connecting assembly comprises an expansion piece and a connecting pin body. An inner cavity is formed in the expansion piece body in a penetrating mode, the expansion piece is provided with a narrow end and a wide end, the narrow end extends forwards to be provided with a first cylindrical connecting section, and a plurality of one-way inner sawteeth are arranged on the inner wall of the first cylindrical connecting section; the connecting pin body penetrates through the inner cavity, one end of the connecting pin body extends forwards to be provided with a first connecting shaft section, a plurality of one-way outer sawteeth are arranged on the outer wall of the first connecting shaft section, and the first cylindrical connecting section and the first connecting shaft section are fixed through meshing of the one-way inner sawteeth and the one-way outer sawteeth. The quick connecting assembly has the advantages that the first connecting shaft section and the first cylindrical connecting section can be reliably connected and fixed together in a sleeving mode through cooperation of the multiple one-way outer sawteeth and the multiple one-way inner sawteeth, the connecting pin body cannot be disengaged from the expansion piece, and therefore it can be guaranteed that the stability of the whole quick connecting assembly is better.
本发明提供一种快速连接组件及连接装置，包括膨胀件以及连接销体；所述膨胀件本体贯穿设置有内腔，所述膨胀件具有窄端和宽端，所述窄端向前延伸设置有第一筒状连接段，所述第一筒状连接段的内壁设置有若干个单向内锯齿；所述连接销体穿过所述内腔，所述连接销体的一端向前延伸设置有第一连接轴段，所述第一连接轴段的外壁设置有若干个单向外锯齿，所述第一筒状连接段与第一连接轴段之间通过单向内锯齿和单向外锯齿齿合固定。本发明的优点：可利用多个单向外锯齿与多个单向内锯齿配合实现将第一连接轴段与第一筒状连接段可靠的套接固定在一起，使连接销体不会与膨胀件脱离，从而能够确保整个快速连接组件的稳固性更好。
