Rapid locking and limiting device of folding net rack

ZHAO ZHANWEI / HOU YANFANG

The invention relates to a quick locking and limiting device for a folding net rack, and discloses a locking and limiting device which is used for connecting an upper hub and a lower hub of the folding net rack together by inserting a self-locking steel column into a self-locking assembly of the upper hub, and carrying out self-locking and limiting on the self-locking steel column through matching of a steel ball and a steel bowl under the elastic force of a compression spring. The self-locking device is characterized by comprising an upper hub assembly, a lower hub assembly, a self-locking steel column and a locking assembly for locking the self-locking steel column, the lower hub assembly is arranged at one end of the self-locking steel column, the locking assembly is arranged in the upper hub assembly, the other end of the self-locking steel column is inserted into the locking assembly, and the locking assembly is arranged in the self-locking steel column. A steel column bottom plate is arranged at one end of the self-locking steel column, the other end of the self-locking steel column is of a conical structure, the lower hub assembly is composed of a lower hub top plate, a lower hub bottom plate, a bottom plate groove and a top plate groove, and the upper hub assembly is composed of an upper hub top plate, a top plate reserved hole, an upper hub bottom plate, a mounting groove, a steel bowl groove, a steel column guide hole and a guide groove.

本发明一种折叠网架的快速锁定限位装置公开了一种通过将自锁钢柱插入上毂盘的自锁组件内将折叠网架的上毂盘和下毂盘连接在一起，在压缩弹簧的弹性力下，通过钢珠配合钢碗对自锁钢柱进行自锁限位的锁定限位装置。其特征在于包括上毂盘组件，下毂盘组件，自锁钢柱以及对自锁钢柱进行锁紧的锁紧组件，所述下毂盘组件设置在自锁钢柱一端，所述锁紧组件设置在上毂盘组件内，所述自锁钢柱插另一端插置于锁紧组件内，所述自锁钢柱一端置有钢柱底板，所述自锁钢柱另一端为锥形结构，所述下毂盘组件由下毂盘顶板、下毂盘底板、底板槽和顶板槽组成，所述上毂盘组件由上毂盘顶板、顶板预留孔、上毂盘底板、安装槽、钢碗槽、钢柱导向孔和导向槽组成。
