摘　　要：提出了一种两级伸缩杆的机械锁设计结构,对锁的安装布置进行了分析,锁紧原理中阐述了锁紧时的工作状态和解锁条件。选用卡簧作为锁的限位部分,进行受力分析得到了开锁时锁的受力和变形的关系,据此确定了锁钩的几何尺寸。最后对设计的锁钩进行了校核分析,验证了设计可行。该锁结构紧凑、工作可靠,可以为两级伸缩装置的内置机械锁设计提供参考。A mechanical lock design structure for two stage telescopic rod is proposed,the working state and unlocking conditions during locking are described in the principle of locking.The circlip is selected as the limiting part of the lock,the relationship between force and deformation is obtained be force analysis,based on this,the geometric dimension of the lock hook is determined.Finally,check analysis proves that design is feasible.The lock has compact structure and reliable work,which can provide reference for the design of built-in mechanical lock of two stage telescopic device.
