The invention belongs to the technical field of lock catches, and particularly relates to a bolt type quick-release traction lock catch for hoisting equipment, which comprises a lock catch body, connecting ring frames are fixedly mounted at two ends of the lock catch body, the two connecting ring frames are coaxially arranged, and the same locking mechanism is arranged on the two connecting ring frames in a penetrating manner. The hinge pin and the two connecting ring frames are spirally connected together, meanwhile, the positions between the hinge pin and the two connecting ring frames are limited through the anti-disengaging mechanism and the handle, and the situation that the hinge pin and the connecting ring frames rotate relatively when a heavy object is hung can be prevented; in the process that the pin shaft drives the anti-falling mechanism to penetrate through the connecting ring frame, lubricating oil accumulated in the sliding grooves can be extruded out, and in cooperation with relative rotation between the connecting ring frame and the pin shaft, the extruded lubricating oil can be evenly coated on the contact face between the connecting ring frame and the pin shaft, so that the pin shaft can smoothly penetrate through the pin shaft, and the service life of the pin shaft is prolonged. Meanwhile, the friction between the pin shaft and the connecting ring frame is reduced.
本发明属于锁扣技术领域,尤其为一种起重设备用插销式快拆牵引锁扣,包括扣体,所述扣体的两端均固定安装有连接环架,两个连接环架同轴设置,两个连接环架上贯穿设置有同一个锁死机构。本发明通过使销轴与两个连接环架之间螺旋连接在一起,同时通过防脱机构与把手对销轴和两个连接环架之间的位置进行限制,能够在悬挂重物时防止销轴与连接环架之间出现相对转动的情况;当销轴带动防脱机构穿过连接环架的过程中,能够将蓄积在多个滑槽内的润滑油挤压出,并且配合着连接环架与销轴之间的相对转动,能够使被挤出的润滑油可以均匀的涂敷在连接环架与销轴之间的接触面,使销轴能够顺利的穿过销轴,同时降低销轴与连接环架之间的摩擦。
