The invention relates to a connecting device capable of realizing self-locking positioning. The connecting device comprises a self-locking seat and a bearing seat movably matched with the self-lockingseat, wherein a self-locking mechanism is mounted between the bearing seat and the self-locking seat; when the self-locking seat is close to or far away from the bearing seat, the self-locking mechanism carries out connecting positioning on the self-locking seat and the bearing seat; and the bearing seat comprises a cylindrical main body, an adjusting screw, a tension spring, an upper end plate and a lower end plate, the upper end plate is mounted at the upper end of the cylindrical main body, a conical hole is formed in the middle of the upper end plate, and the lower end plate is mounted atthe lower end of the cylindrical main body. The connecting device has the advantages that a self-locking device is mounted between two adjacent telescopic arms, the structure is reasonable, the operation is convenient, the cost is reduced, and especially through the arrangement of the self-locking device and the improvement of the self-locking seat and the bearing seat, the effects of being safeand reliable and being convenient to maintain in the hoisting field are achieved.

    本发明涉及一种可自锁定位的连接装置,包括自锁座以及与自锁座动配合的承接座,该承接座与自锁座之间安装有自锁机构;当自锁座接近或远离所述的承接座时,所述的自锁机构将自锁座与承接座进行连接定位;所述的承接座包括筒状主体、调节螺杆、拉簧、上端板和下端板,在所述筒状主体的上端安装有上端板,该上端板的中部开设有锥形孔,所述筒状主体的下端安装有下端板。本发明的优点是:本发明在相邻两伸缩臂之间安装有该自锁装置,结构合理,操作方便,降低了成本,尤其是自锁装置的设置以及对自锁座和承接座的改进,实现了在起吊领域安全可靠,维护方便的效果。
