Technological opening prevention lock cylinder
The invention discloses a technological opening prevention lock cylinder. The technological opening prevention lock cylinder comprises a lock shell, a lock liner and marble components, wherein marbles of at least one marble component consist of a main marble and a technological opening prevention marble connected as a whole; a conical groove is formed in the technological opening prevention marble; in addition, the slip of a conical end of a cross grid into the conical groove is realized through the conical groove and the conical end between the technological opening prevention marble and the cross grid under the effect of a pressure spring; in a door locking state, the cross grid can be hidden in the lock liner, or can be partially exposed in a cross grid slip slot of the lock shell; when lawbreakers perform the technological opening, the lock liner slightly rotates, and a pin in the lock liner follows to slightly rotate; the outer end of the cross grid is exposed in the cross grid slip slot, or the inner and outer ends of the cross grid are respectively ejected against the inclined surface of the conical groove and the inner wall of the lock shell under the effect of the inclined surface of the conical groove, so that the lock liner cannot continuously rotate to achieve the purpose of preventing the technological opening; and the technological opening prevention lock cylinder is more reasonable in structure and stronger in antitheft performance.
