Integrated safe interlock device used for lock-ring type quick open blind plate structure

The invention discloses an integrated safe interlock device used for a lock-ring type quick open blind plate structure. An alarm threaded rod upper shell and an alarm threaded rod lower shell are fixedly connected through a thread, and the alarm threaded rod upper shell and the alarm threaded rod lower shell cooperate to form an enclosure space; an upper pressing cover, a rubber membrane and a lower pressing cover are arranged on a lock cylinder shaft in sequence in a sleeving mode, and the lock cylinder shaft is screwed and sealed through a thread. An O-shaped rubber sealing ring is installed on the surface of the middle inside the alarm threaded rod lower shell. Steps are arranged at the end of an alarm threaded rod rotating handle, and the alarm threaded rod upper shell is fixedly connected with the steps at the end of the alarm threaded rod rotating handle through two groups of symmetric pins; a groove is formed in the middle of the alarm threaded rod rotating handle in the axial direction, and a stroke limiting rod moves along the groove; a handle pin is installed on the alarm threaded rod rotating handle in the radial direction, and the handle pin limits the axial displacement of a lock ring embedded block. According to the device, it is avoided that under the condition that residual pressure exists, the alarm threaded rod and the lock ring embedded block are taken out mistakenly, and an operator is prevented from injury and the environment is prevented from pollution by medium.
