A padlock including a lock body (1), a lock shackle (2) movable between locking and releasing positions, and, inside the lock body, bolt means (5) for securing and releasing the shackle (2) in its locking position, and a cylinder lock mechanism (3) for controlling the bolt means (5). The cylinder lo
A padlock including a lock body (1), a lock shackle (2) movable between locking and releasing positions, and, inside the lock body, bolt means (5) for securing and releasing the shackle (2) in its locking position, and a cylinder lock mechanism (3) for controlling the bolt means (5). The cylinder lock mechanism (3) is replaceably mounted in a separate casing-like fixing unit (6), which is detachably fixed to the lock body, (1). The fixing unit (6) has inner guiding surfaces (6c), which correspond to the outer shape of the cylinder lock mechanism (3, 3', 3"), to provide both radial and axial support for the cylinder lock mechanism (3, 3', 3").

1. A padlock comprising: a lock body that defines a chamber bounded by an inner peripheral surface of the lock body, a fixing unit that is located in the chamber of the lock body and has an outer peripheral surface that substantially matches the inner peripheral surface of the lock body, the fixing unit being detachably fixed to the lock body and defining a cavity that is substantially completely laterally bounded by lateral guiding surfaces and is axially bounded by an end surface, a lock shackle mounted in the lock body and movable relative to the lock body between a locking position and a releasing position, a bolt element in the lock body for selectively securing and releasing the lock shackle in its locking position, and a cylinder lock mechanism for controlling the bolt element, the cylinder lock mechanism being located at least partially in the cavity of the fixing unit and substantially completely surrounded laterally by the lateral guiding surfaces of the fixing unit, the lock mechanism having an end surface that is presented towards the end surface of the fixing unit and having lateral surfaces that are presented towards the lateral guiding surfaces of the fixing unit, whereby the fixing unit provides both axial and radial support for the lock mechanism. 2. A padlock according to claim 1, wherein the fixing unit is fabricated from a different material from that of the lock body. 3. A padlock according to claim 1, wherein the fixing unit is fabricated from a different material from the cylinder lock mechanism. 4. A padlock according to claim 1, wherein the fixing unit is made from chilled steel. 5. A padlock according to claim 1, wherein the cylinder lock mechanism has an axial direction, the fixing unit has first and second mutually perpendicular linear dimensions in a plane perpendicular to said axial direction, said first dimension is a maximum linear dimension of the fixing unit in said plane, and said first dimension is greater than said second dimension. 6. A padlock according to claim 1, wherein the cylinder lock mechanism includes a torsion element that is turnable about a central axis thereof, the fixing unit has first and second mutually perpendicular linear dimensions in a plane perpendicular to said central axis, said first dimension is a maximum linear dimension of the fixing unit in said plane, and said first dimension is greater than said second dimension. 7. A padlock according to claim 1, wherein the cylinder lock mechanism includes a torsion element that is turnable about a central axis thereof, the chamber of the lock body is longer than the fixing unit in the axial direction of the torsion element, and the fixing unit is removable from the chamber. 8. A padlock according to claim 1, wherein the lateral surfaces of the cylinder lock mechanism include a first lateral surface portion that engages a corresponding lateral guiding surface portion of the fixing unit and also include a second lateral surface portion that is spaced from the lateral guiding surfaces of the fixing unit. 9. A padlock according to claim 1, wherein the lock body has first and second opposite end surfaces and is formed at its first end surface with two parallel bores for receiving respective legs of the shackle and is formed at the second end surface with an opening for providing access to the chamber, and the fixing unit is located in said opening and is removable from the cavity by way of the opening when detached from the lock body.
