Threadless self-locking wall penetrating pulling rod
The invention discloses a threadless self-locking wall penetrating pulling rod. The pulling rod is composed of an opposite-pulling rod, an L-shaped fixed part, a fixed column, a fixed nut, a hollow screw rod and an opposite-pulling nut. The opposite-pulling nut is screwed on the hollow screw rod, and one end of the opposite-pulling rod is sleeved with the hollow screw rod; the fixed nut is screwed at the lower end of the fixed column, and the fixed column penetrates a fixed column penetrating hole of the L-shaped fixed part, and the L-shaped fixed part leans against the wall; the opposite-pulling rod penetrates through a wall, and then is sequentially inserted into a first penetrating hole of the L-shaped fixed part and a second penetrating hole of the fixed column; the hollow screw rod slides to be blocked by a limiting block of the opposite-pulling rod, and then the fixed nut is screwed to enable the other end of the opposite-pulling rod to be fixed; and finally, the opposite-pulling nut is rotated towards the other end of the opposite-pulling rod to achieve the aim of tightening the opposite-pulling rod. The threadless self-locking wall penetrating pulling rod can achieve the aim that a common reinforcing steel bar is used for replacing the screw rod, and therefore the aims that materials are conveniently taken, and in the wall penetrating process, a PVC casing pipe is not needed are achieved; and the threadless self-locking wall penetrating pulling rod is simple in structure, convenient to dismount and large in turnover frequency.
