FIELD: construction.SUBSTANCE: this invention relates to a lever lock, in particular, to lever lock design, comprising a pin cylinder lock and its key. Due to technical imperfection of available lever locks, their low resistance to opening with the help of technical means and complexity of replacement this invention proposes lever lock design comprising a pin cylinder lock and its key, including a body formed by means of connection of an upper cover and a lower cover, and a movable crossbar arranged in the body, levers acting jointly with the crossbar, a fixing plate of the lever lock, tightly pressed to the lever, on the upper and lower covers there are keyholes for a lever lock arranged oppositely to each other, differing by the fact that in the body there is a pin cylinder lock installed in the body, besides, the centre of the keyhole of the pin cylinder lock and centres of keyholes of the lever lock of the upper cover and lower cover are arranged on one line.EFFECT: due to a combination of coding of a pin cylinder lock and a lever lock this design of a lever lock differs by complexity of making a key copy, good resistance to opening with the help of technical means, to a considerable extent high resistance to break-in, high safety of use and convenience of lock replacement.7 cl, 15 dwg |
