Abstract

An anti-tamper cylinder lock comprising exterior and interior cylinder housing 1, 2, coupled by bridge portion 3 and exterior and interior rotating barrels 11, 12 with exterior and interior transmission member 12, 22 selectively coupling rotation of barrel to cam 4. An axially sliding pin 41 in cam 4 normally retained in first position with cam free to rotate, and upon snapping/removal of exterior cylinder the sliding pin 41 is no longer retained in first position and moves to second position under bias of sliding driver/blocking pin 23 which couples cam 4 to the interior barrel upon lock snapping. Preferably balance pin 7 in cam maintains position of sliding and blocking pins 41, 23 prior to lock snapping. A sealing gasket 5 is provided between exterior barrel and portion 31 of bridge to seal hole 100 through which transmission member 12 passes. The seal 5 prevents liquid entering and being used to freeze sliding pin 41 which would otherwise circumvent anti-tamper security pin 23. Preferably drainage channel 300 permits expelling of liquid.
