The invention belongs to the technical field of mechanical lock type connecting mechanisms, and particularly relates to a mechanical lock type connecting mechanism for a hard tow bar of a wrecker and a using method and application of the mechanical lock type connecting mechanism. Comprising a hanging frame connected with a wrecker, a quick-change transition support connected with a hard tow bar and a mechanical lock arranged in the quick-change transition support. The quick-change transition bracket is connected with the hitching frame in a hitching manner; the mechanical lock is rotationally connected with the interior of the quick-change transition support. The mechanical lock is connected with the hanging frame in an inserted mode. The invention further comprises a using method and application of the mechanical lock type connecting mechanism. On the basis of a traditional hard tow bar hanging structure, the structure of the hanging position is changed, the quick-change transition support, the mechanical lock and the shifting fork easily-shifting mechanism are additionally arranged, and hanging and disengaging of the hard tow bar are achieved. The quick hooking and dismounting device is suitable for quick hooking and dismounting of all mechanical structures, connection and disconnection of structural parts can be achieved without the help of external tools, hooking is reliable, and operation is convenient.

    本发明属于机械锁式连接机构技术领域,具体涉及用于清障车硬拖杆的机械锁式连接机构及使用方法和应用。包括与清障车连接的挂接架,与硬拖杆连接的快换过渡支架,以及设于快换过渡支架内部的机械锁;所述快换过渡支架通过挂接的方式与挂接架连接;所述机械锁与快换过渡支架的内部转动连接;所述机械锁通过插接的方式与挂接架连接。本发明还包括一种机械锁式连接机构的使用方法和应用。本发明在传统的硬拖杆挂接结构的基础上,更改挂接处结构,增加快换过渡支架,机械锁具,轻松拨动拨叉机构,实现硬拖杆的挂接和脱离。本发明适用于所有机械结构的快速挂接拆装,可不借助外部工具实现结构件的连接和脱离,挂接可靠、操作方便。
