The locking structure comprises a shell, a hook head, second gears and long racks, wherein guide pillars are uniformly and fixedly connected to the bottom surface of the interior of the shell and sleeved with springs, a flat plate is slidably connected to the guide pillars, the bottom end of the flat plate abuts against the top ends of the springs, the hook head is fixedly connected to the flat plate and penetrates through the bottom end of the shell, short racks are fixedly connected to the left and right ends of the flat plate, first gears engaged with the short racks are arranged on the outer sides of the short racks, short shafts are fixedly connected to the first gears, and installation blocks are fixedly connected totwo ends of the short shafts. The arranged self-locking structure can perform automatic unlocking when a crane puts down an object after moving the heavy object to a designated site, the traditional tedious step of manually pushing away an anti-off pin and taking out a steel wire rope is omitted, and use is more convenient due to automatic unlocking and putting.

    本发明公开了一种钩头装置的锁紧结构,包括壳体、钩头、第二齿轮和长齿条,所述壳体内部的底面上均匀固定连接有导柱,并且所述导柱上均套设有弹簧,所述导柱上滑动连接有平板,并且所述平板的底端与弹簧的顶端相抵,所述平板上固定连接有钩头,并且所述钩头穿过壳体的底端,所述平板的左右两端均固定连接有短齿条,并且所述短齿条的外侧设置有与其相互啮合的第一齿轮,所述第一齿轮上固定连接有短轴,并且所述短轴的两端均固定连接有安装块。本发明设置的自锁结构在起吊机将重物移到指定地点后放下物体时就会自动解锁,解决了传统人工手动拨开防脱销取出钢丝绳的繁琐步骤,自动解锁放料使用更加方便。
