    • A lock cylinder mechanism with anti-theft function, comprises a lock cylinder assembly comprising a lock cylinder shaft sleeve, a lock cylinder block inserted in the lock cylinder shaft sleeve in a rotating fit, a key slot arranged in the said lock cylinder block and a retractable row of coded pin tumblers arranged on at least one inner wall of the slot. The key to the lock cylinder assembly has upper and lower end faces of the key being provided with coded slots matched with the coded pin tumbler. The inner side wall of the said key slot is provided with a through slot which penetrates through the lock cylinder block while the said through slot is internally provided with an auxiliary pin tumbler which is a sliding fit, and
      the wall of the key slot is provided with a positioning slot which intersects with the key slot; the said positioning slot is internally provided with a positioning pin; the top end surface of the insertion end of the key is provided with at least one open slot adapted to engage with or locate on the positioning pin, and the upper and lower end surfaces of the key are provided with at least one clamping slot to engage with the auxiliary pin tumbler.

    • A break-in resistant cylinder (1) comprising a stator (3) provided with a substantially cylindrical receptacle (4) for a rotor (5). The rotor (5) and the stator (3) are affected by at least one channel (6) for at least one respective pin (7), which can move slidingly within it. The arrangement for retention has the least one pin (7) partly in the rotor (5) and partly in the stator (3), causing the locking of the rotor (5). The open arrangement provides for alignment of an end edge (8) of the at least one pin (7) with the interface surface between the stator (3) and the rotor (5), obtained by means of the insertion of an adapted key (2) having a contoured profile in an opening (9) of the rotor (5) that faces the at least one channel (6) and causes the free rotation of the rotor (5) with respect to the stator (3). The at least one pin (7) comprises an ogive (10) provided with a contoured cavity (11) and a coding part (12) provided with two mutually opposite protruding tabs (13, 14) and with a substantially spherical central portion (15). The at least one channel (6) of the rotor (5) comprises a first part that has a substantially larger diameter than the substantially spherical central portion (15) and a second part whose diameter is substantially smaller than the diameter of the substantially spherical portion (15) and larger than the diameter of a first protruding tab (13); the front of the first protruding tab (13), upon the insertion of the key (2) in the opening (9) of the rotor (5), is accommodated within a respective profiled slot (18) with consequent substantial complete insertion of the second protruding tab (14) within the cavity (11) of the ogive (10) according to the open arrangement.
    • 一种耐冲击缸(1),包括定子(3),所述定子(3)设置有用于转子(5)的基本上圆柱形的容器(4)。 转子(5)和定子(3)受到用于至少一个相应销(7)的至少一个通道(6)的影响,其可以在其内滑动地移动。 用于保持的装置具有部分地位于转子(5)中并且部分地在定子(3)中的至少一个销(7),导致转子(5)的锁定。 开放装置提供了至少一个销(7)的端部边缘(8)与定子(3)和转子(5)之间的接合面的对准,借助于插入适配的键( 2)在所述转子(5)的开口(9)中具有面向所述至少一个通道(6)并且使所述转子(5)相对于所述定子(3)自由旋转的轮廓。 所述至少一个销(7)包括设置有轮廓空腔(11)和编码部分(12)的齿轮(10),编码部分(12)设置有两个彼此相对的突出突片(13,14)和基本上球形的中心部分 )。 转子(5)的至少一个通道(6)包括具有比基本上球形的中心部分(15)大得多的直径的第一部分和直径基本上小于基本上球形部分直径的第二部分 (15)并且大于第一突出突片(13)的直径; 在将钥匙(2)插入转子(5)的开口(9)中时,第一突出突片(13)的前部容纳在相应的型材槽(18)内,从而大大完全插入 根据打开布置,第二突出突片(14)在所述凹槽(10)的空腔(11)内。
