The invention discloses a locking block. The locking block comprises a locking block body, a coupling shaft, a driving part and a limiting arm with a limiting groove, wherein the limiting groove is formed in the extending face, with the radian, of the limiting arm and provided with a first limiting wall and a second limiting wall which are in a non-mirror image shape and are connected with each other, and the limiting groove is used for limiting the freedom degrees of a bolt crankshaft in a safety belt lock catch in the limiting groove in two different directions; the limiting groove is formedin the extending face, with the radian, of the limiting arm, the first limiting wall and the second limiting wall are arranged to be of a non-mirror-image structure, the bolt crankshaft can be limited through the simplified structure, the space occupied by the locking block can be reduced, and the cost for manufacturing the locking block is reduced; and the size of the second limiting wall is small, and therefore when the locking block is installed in the safety belt lock catch, the space occupied by the locking block in the safety belt lock catch is reduced, and meanwhile the space occupiedby other parts in the safety belt lock catch is reversely increased.

    本申请公开一种锁止块,包括:锁止块本体,转接轴,驱动件以及具有限位凹槽的限位臂;限位凹槽形成于限位臂的具有弧度的延展面上,且具有呈非镜像且相互连接的第一限位壁和第二限位壁,用于限定安全带锁扣中的栓机轴在限位凹槽中的两个不同方向的自由度。本申请的限位凹槽形成于限位臂的具有弧度的延展面上,且通过将第一限位壁和第二限位壁设置为非镜像结构,其不仅通过简化的结构可以对栓机轴起到限位作用,还可以减小锁止块所占有的空间,降低制造锁止块的成本。且基于第二限位壁的体积较小,从而在锁止块安装在安全带锁扣中时,减小了锁止块再安全带锁扣中所占有的空间,同时也反向的增加了安全带锁扣中其它零部件可占有的空间。
