#CMT# #/CMT# The device has a lock body (1) integrated to a cover of a case and with a passage orifice (10). A cylindrical barrel (2) rotates in the orifice between open and closed positions by an action of a driving profile (52) carried by a key (5). A filter element (3) has an opening traversed by the driving profile for accessing and driving the barrel. The opening has a shape allowing the passage of the driving profile by translation along a rotation axis of the barrel, while limiting angular position around a same axis in which the passage of the key is possible. #CMT#USE : #/CMT# Lock device for immobilizing a cover and a body of a case or an enclosure that is utilized for forming a distribution installation e.g. electrical installation, gas system, telephony equipment or telecommunication installation. #CMT#ADVANTAGE : #/CMT# The shape of the opening allows the passage of the driving element by translation along the rotation axis of the barrel, thus avoiding the hooking of the lock device using a simple tool e.g. screwdriver, without damaging the filter element and the lock device in a visible manner. The device is simple and inexpensive to fabricate and assemble. The configuration of the device is such that it is easy to open, avoids fraudulent opening, and ensures easy detection of the fraudulent opening. The device reduces the risk of default or bad closing of the enclosure, and ensures better ergonomics and operating robustness. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded and sectional view of a lock device with a key. 1 : Lock body 2 : Cylindrical barrel 3 : Filter element 5 : Key 10 : Passage orifice 52 : Driving profile. |
