The invention discloses a hook pin capable of being automatically locked, which comprises a connecting frame, a threaded connecting head connected to the connecting frame, and the threaded connecting head is in threaded installation with a vehicle; a hook pin device is connected to the end of the connecting frame in a penetrating mode, a limiting mechanism is installed on one side of the connecting frame, the hook pin device is connected with the limiting mechanism in a penetrating and clamping mode, and the hook pin device is used for one-way locking of the limiting mechanism. By means of the arrangement mode that a hook pin device and a limiting mechanism are matched, when a hook pin shaft and a connecting frame are inserted in a penetrating mode, a one-way locking mechanism moves in the direction of the limiting mechanism in a penetrating mode, and after an inserting head and a limiting ring are inserted in a penetrating mode, a multi-direction locking assembly can be unfolded after penetrating through the limiting ring; therefore, the multidirectional locking assembly abuts against the limiting ring, one-way locking of the limiting ring is achieved, using is more convenient and faster, the stability is higher compared with threaded connection, and the stability of the trailer is higher.
本发明公开了一种可自动锁定的挂钩销,包括:连接架,连接架上连接有螺纹连接头,螺纹连接头与车辆进行螺纹安装;连接架的端部穿插连接有挂钩销装置,连接架的一侧安装有限位机构,挂钩销装置与限位机构穿插卡接,挂钩销装置用于对限位机构的单向锁定。本发明利用挂钩销装置和限位机构相配合的设置方式,在挂钩销轴与连接架进行穿插时,单向锁定机构向着限位机构的方向进行穿插移动,直至穿插头与限位环穿插后,多向锁定组件穿过限位环后会进行展开,从而使得多向锁定组件抵在限位环上,以实现对限位环的单向锁定,使用起来更加便捷,且相对螺纹连接稳定性更高,使得拖车的稳定性更高。
