The invention relates to the related technical field of automobile accessories, in particular to a safety belt locking mechanism which comprises a mounting support, a rotating shaft, a winding shaft, a volute spring and a high-speed self-locking structure, rotating holes are formed in side plates at the two ends of the mounting support, and the rotating shaft is rotatably mounted in the rotating holes in the mounting support; a spring positioning groove is formed in the end part of the rotating shaft; a safety belt locking mechanism formed by combining a mounting bracket, a rotating shaft, a rolling shaft, a volute spring and a high-speed self-locking structure is arranged, the high-speed self-locking structure is arranged to be formed by combining an outer chuck, an inner turntable and a self-locking assembly, and the self-locking assembly is arranged to be formed by combining a centrifugal latch, a guide rod seat, a guide rod, a reset spring and a limiting cap; therefore, when the belt body of the safety belt is pulled out at a high speed, the tooth ends of the centrifugal clamping teeth move outwards through centrifugal force generated by the centrifugal clamping teeth, the tooth ends and the self-locking grooves in the outer chuck form a self-locking function, and the safety protection function is achieved.

    本发明涉及汽车配件相关技术领域,具体为一种安全带用锁止机构,安全带用锁止机构包括安装支架、转轴、收卷轴、涡状弹簧和高速自锁结构,安装支架的两端侧板上均开设有转孔,转轴转动安装在安装支架上的转孔中,转轴的端部开设有弹簧定位槽;通过设置由安装支架、转轴、收卷轴、涡状弹簧和高速自锁结构组合构成的安全带用锁止机构,并通过将高速自锁结构设置成由外卡盘、内转盘和自锁组件组合构成,并将自锁组件设置成由离心卡齿、导杆座、导杆、复位弹簧和限位帽组合构成,从而让安全带的带体在高速拉出时,通过离心卡齿产生的离心力,以让离心卡齿的齿端外移,从而与外卡盘上的自锁槽形成自锁作用,从而起到安全防护作用。
