The invention provides a safety belt tensioner which comprises a shell, a mounting hole is formed in the outer wall of the shell, a rotating shaft is rotatably connected to the interior of the mounting hole, a safety belt body is arranged on the outer wall of the rotating shaft, a positioning hole is formed in the safety belt body, a friction structure is arranged in the shell, and the friction structure is arranged in the shell. And a connecting groove is formed in the middle of the outer wall of the shell. The safety belt is reasonable in design, by arranging the limiting structure capable of moving downwards, the limiting structure is clamped with the positioning hole in the safety belt body, so that the safety belt at multiple positions can be fixed, meanwhile, the friction structure is pushed to move outwards in the downward moving process of the limiting structure, and the friction effect is improved. And the friction structure and the rotating shaft are matched with each other to secondarily clamp the safety belt body, so that the safety belt can be tensioned and fixed.
本发明提供一种安全带拉紧器,包括壳体,所述壳体的外壁开设有安装孔,所述安装孔的内部转动连接有旋转轴,所述旋转轴的外壁设置有安全带本体,所述安全带本体的内部开设有定位孔,所述壳体的内部设置有摩擦结构,所述壳体外壁的中间开设有连接槽。本发明设计合理,通过设置的可以向下移动的限位结构,使限位结构与安全带本体内部的定位孔卡合,从而可以对多个位置的安全带进行固定,同时限位结构向下移动的过程中还会推动摩擦结构向外移动,使摩擦结构和旋转轴之间相互配合对安全带本体进行二次夹紧,从而可以对安全带进行拉紧和固定。
