摘要
目的探讨内窥镜条件下检验技术开锁痕迹的方法。方法通过对内窥镜的分析,探索适用内窥镜的选择标准;通过分析锁芯结构,确定内窥镜检验开锁痕迹的工作通道和进入锁芯的方法;通过内窥镜观察锁芯内痕迹实验,研究内窥镜下观察技术开锁痕迹的方法;以传统的方法研究L形开锁器痕迹,验证内窥镜下检验技术开锁痕迹的可行性。结果检验开锁痕迹适合用硬性直杆式内窥镜,根据圆头弹子位置确定工作通道,用移动锁具或窥镜的方法将内窥镜送入锁芯。结论内窥镜下检验开锁痕迹应选择0.5 mm、1.0 mm直杆式硬性内窥镜;选择与圆头弹子相同或相邻的空间作为工作通道,按照移动锁具或内窥镜的方法进入锁芯,可实现圆头弹子球面、柱面、孔槽壁上的痕迹观察。
Objective To investigate unlocking marks on L-shaped picklock under borescopes. Method The appropriate type of borescopes was first selected through comparative study. Then the proper inspection channel was chosen based on the analysis of the lock cylinder structure. The marks on the lock cylinder were inspected under the borescope to explore a corresponding examination method. Afterwards, the unlocking marks on L-shaped picklock were studied to evaluate the feasibility of inspection under borescopes. Results The rigid borescope suits best for the unlocking mark examination. The inspection channel was chosen based on the position of the round marble. The borsescope was inserted into the lock cylinder through moving locks or under normal scopes. Conclusion 0.5 or 1.0 mm straight rigid borecopes are suitable for examination. The working channel should be at the same or similar size with the round marble. The borsecope could be inserted into the lock cylinder by moving normal locks or scopes. The established method will enable investigators to observe the unlocking marks on the spherical, cylindrical and hole slot wall of the round marble.
