Problems solved by technology

[0011] The insertion action described above is suitable for virtually all kinds of lock cylinders and is very dangerous due to the fact that it often does not even leave traces that would indicate that a theft has occurred

Embodiment Construction

[0060] Referring to the drawings, reference numeral 1 generally denotes an anti-insertion lock cylinder.

[0061] The lock cylinder 1 comprises a fixed disc 2 with a generally cylindrical longitudinal hole 3 for receiving a rotor 4 with a longitudinal slot 5 for inserting a key 6 for opening the lock cylinder 1 .

[0062] The rotating body 4 and the fixed disk 2 comprise a plurality of channels 7: when the lock cylinder 1 is in the closed state, the part of the channel 7 contained inside the fixed disk 2 and the part of the channel contained inside the rotating body 4 are substantially aligned and face each other. right.

[0063] Channels 7 are used to accommodate respective coding pins 8 , detent pins 9 and optional elastic means 7 a, which are used to prevent the rotation of the rotor 4 in the fixed disk 2 when the key 6 is not in the longitudinal slot 5 .

[0064] At least one locking pin 9 has a sleeve 10 and a spike 11 . In particular, the spike 11 is provided with a sh...

Abstract

A break-in resistant cylinder (1) for locks, comprises a stator (2) provided with a substantially cylindrical longitudinal cavity (3) for accommodating a rotor (4) with a longitudinal recess (5) for the insertion of a key (6). The rotor (4) and the stator (2) comprise a plurality of channels (7) which are substantially aligned and face each other (when the cylinder (1) is in the closed configuration); the channels (7) accommodate respective coding pins (8), tumbler pins (9) and any elastic means (7a) designed to prevent the rotation of the rotor (4) within the stator (2) if the key (6) is not present in the longitudinal recess (5). At least one of the tumbler pins (9) comprises a bush (10) and a spike (11); the stem (12) of the spike (11) has a smaller diameter than the inside diameter of the bush (10) and is longer than the bush (10). The spike (11) is arranged so that its head (13) is directed toward the bottom of the channel (7) of the stator (2) and rests against the elastic means (7a) and the free end (15) of the stem (12) rests against the lower surface of the coding pin (8). The lower surface of the bush (10) rests against the collar (14) of the head (13) of the spike (11) proximate to the coupling of the stem (12).

Description

technical field [0001] The present invention relates to an anti-insertion lock cylinder, in particular adapted to hinder insertion action, which action involves impacting at least a part of said lock cylinder. Background technique [0002] Existing lock comprises lock core (wherein has key hole), and this lock core has a fixed disk and a rotating body, and they are connected with each other by means of a plurality of coding pins and brake pins that can slide in the fixed disk and rotating body channel. Coupling: When the lock cylinder reaches the closed state (the key is not inserted or the key is inserted but not rotated relative to the insertion structure), each fixed disk channel is opposite to and aligned with the rotor channel. [0003] An axially acting elastic element is located between the bottom of the channel of the fixed disc and the lower surface of the brake pin, which is used to isolate the brake pin from the above-mentioned bottom so as to avoid the influence ...
