The invention discloses a chain stopping and dragging combined chain bracelet mechanism for a chain block, which is provided with a hand chain wheel and a hand zipper in a closed state, the hand zipper penetrates through a chain locking device in a sleeving manner, and the chain locking device is integrally formed by a through chain ring body and a chain stopping body formed by bending the upper part of the through chain ring body; the left chain stopping hook and the right chain stopping hook are formed by oppositely bending the two end sides of the chain stopping base strip, the hook body part of the right chain stopping hook and the right upper end of the through chain ring body are connected into a whole in a transition mode, and the middle partition strip and the left upper end of the through chain ring body are connected into a whole in a transition mode. A hook head of the left zipper stopping hook and a hook head of the right zipper stopping hook both face the zipper stopping base strip, a right limiting hook cavity of the right zipper stopping hook penetrates through the zipper through ring body, and a space interval is formed between the left zipper stopping hook and the zipper through ring body and used for enabling a zipper link of a hand zipper to enter and exit from a left limiting hook cavity of the left zipper stopping hook. After the double stations of the chain locking device are designed into the chain passing ring body and the chain stopping body, the hand zipper can be clamped, and the purpose of limiting and stopping pulling of the hand zipper to prevent the load from ascending and descending is achieved.
本发明公开了一种止链与曳链兼备的手拉葫芦用手链机构,具有手链轮和闭合状态的手拉链,手拉链穿套锁链器,锁链器由通链环体和经该通链环体的上部弯折成形的止链体一体组成,止链体由止链基条、中隔条和自止链基条二端侧相向弯曲形成的左止链勾、右止链勾组成,右止链勾的勾体部与通链环体的右上端过渡连接成一体,中隔条与通链环体的左上端过渡连接成一体,左止链勾的勾头和右止链勾的勾头均朝向止链基条,右止链勾的右限位勾腔贯通通链环体,左止链勾与通链环体之间具有用于供手拉链的链节进、出左止链勾其左限位勾腔的空间间隔。锁链器双工位设计成通链环体和止链体后,能够将手拉链卡顿,实现了限止手拉链拉动以阻止载荷升降的目的。
