The invention provides an anchoring safety hook capable of being repeatedly used and convenient to disassemble and assemble. The anchoring safety hook comprises a hook base and an expansion sleeve fixedly arranged on the hook base, the expansion sleeve is used for stretching into a preset hole of a fixed body, and an expansion opening is formed in the end, away from the hook base, of the expansionsleeve. A screw is arranged in the expansion sleeve, the head end of the screw stretches out of the expansion sleeve, the tail end of the screw stretches out from the end, away from the hook base, ofthe expansion sleeve, and an expansion head is arranged at the tail end of the screw. A nut is in screw joint to the screw. When the nut is screwed down, the screw moves from the tail end to the headend, the expansion head expands the expansion sleeve so as to achieve anchoring with the fixed body, and after the nut is unscrewed, external force is applied to the screw to enable the screw to movefrom the head end to the tail end, the expansion head is disengaged from the expansion sleeve, and the expansion sleeve contracts so as to facilitate disassembling. The anchoring safety hook is simple in structure and reasonable in design, can be repeatedly used, and has the characteristics of being convenient to use and easy to disassemble and assemble.
本发明提供一种可重复使用并便于拆装的锚固安全挂钩,包括:挂钩座和固设在挂钩座上的膨胀套筒,所述膨胀套筒用于伸入到固定体的预设孔中,所述膨胀套筒的远离挂钩座的一端具有膨胀开口;所述膨胀套筒内设有螺杆,螺杆的首端伸出膨胀套筒,螺杆的尾端由膨胀套筒的远离挂钩座的一端伸出,螺杆的尾端具有膨胀头;螺杆上螺接有螺母,在拧紧螺母时,螺杆由尾端向首端移动,膨胀头胀开膨胀套筒以实现与固定体锚固,在拧松螺母后通过对螺杆施加外力,使得螺杆由首端向尾端移动,膨胀头脱离膨胀套筒,膨胀套筒收缩以便于拆除。本发明结构简单,设计合理,可以实现重复使用,并具有使用方便、拆装容易的特点。
