According to the unlocking assembly and the lock cylinder set, the unlocking assembly comprises an inner core, an ejector rod and a key, the inner core is configured to be of a circular tubular structure, and a key hole is formed in the inner core; the ejector rod is installed in the key hole and matched with the inner core in a limiting mode, and a cavity is defined between the ejector rod and the hole wall of the key hole. The key comprises an insertion pipe which can be matched with the cavity in an inserted mode so that the insertion pipe and the inner core can be limited in the circumferential direction. Moreover, when the insertion pipe is matched with the cavity in an inserted mode, the ejector rod can push the dial wheel core to be inserted into the dial wheel under pushing of the key, and the inner core can be limited in the circumferential direction through the dial wheel core and the dial wheel. Therefore, on one hand, the inner core can be made of a circular tube, so that the processing cost can be reduced, the quality of the inner core product is improved, and the inner core product is prevented from being deformed due to external force; and on the other hand, the size of the cavity for inserting the insertion tube on the key on the inner core is small, and no enough space is provided for inserting tools used during technical unlocking, so that the lock cylinder applying the unlocking assembly can be prevented from being technically unlocked.
本申请请求保护的开锁组件及锁芯套装，开锁组件包括内芯、顶杆和钥匙，内芯配置为圆形管状结构，内芯上开设有钥匙孔；顶杆安装于钥匙孔内并与内芯限位配合，并且，顶杆与钥匙孔的孔壁之间围合形成有空腔；钥匙包括插管，插管能够与空腔插接配合，以使插管与内芯周向限位；并且，当插管与空腔插接配合时，顶杆能够在钥匙的推挤下推顶拨轮芯插入拨轮，并使内芯能够通过拨轮芯与拨轮周向限位。这样一方面该内芯可采用圆管制作，相不仅可降低加工成本，而且也提高了该内芯产品的品质，防止受外力作用而变形；另一方面内芯上供钥匙上插管插入的空腔尺寸较小，没有足够的空间供技术开锁时所用工具的插入，可防止应用有该开锁组件的锁芯被技术开启。
