The invention relates to the field of safety belt retractors, aims to solve the problem of pre-tightening of safety belt retractors, and discloses a pre-tightening structure of a safety belt retractor, which comprises a storage box and a positioning plate, the storage box and the positioning plate are fixedly assembled, and a rotating shaft is transversely inserted in the storage box; the middle of the surface of the rotating shaft is fixedly sleeved with a friction cylinder, the two ends of the surface of the rotating shaft are symmetrically sleeved with second chain wheels, supporting frames arranged outside the rotating shaft in a sleeving mode are arranged between the second chain wheels and the friction cylinder, and the two supporting frames are arranged on the left side and the right side respectively. By means of the mode that the large wheel drives the small wheel, when the safety belt is pulled out, the safety belt in the retractor is rapidly pulled out to be positioned, the number of the safety belt remaining in the retractor is small, and therefore the danger caused by failure of the safety belt retractor is prevented, and pre-tightening of the safety belt is achieved.
本发明涉及安全带卷收器领域,其目的是为了解决安全带卷收器预收紧的问题,公开了一种安全带卷收器预收紧结构,包括储存盒和定位板,储存盒与定位板之间固定装配,位于储存盒内部横向穿插有旋转轴,位于旋转轴表面中部固定套装有摩擦筒,位于旋转轴表面两端对称套装有第二链轮,位于第二链轮与摩擦筒之间设置有套装在旋转轴外的支撑架,支撑架设置成两个分别装在左右两侧。本发明通过大轮带动小轮的方式,在将安全带拉出的时候快速将卷收器内的安全带拉出进行定位,使卷收器内存留的安全带较少,从而防止安全带卷收器失效时带来的危险,实现对安全带的预收紧。
