A lock core structure composed of a lock core seat, a lock core shell, a push plate, lock plates, washers, a positioning plate, a latch lever, a brake bolt plate pushed by a compression spring, a positioning baffle, and a retaining ring. An accommodating chamber of the seat is provided with an accommodating groove, a ring groove, a shaft hole and a groove, an inner bottom surface of the shell is provided with a slide groove for disposing the push plate, the brake bolt plate is provided in the accommodating groove, and provided with a pivot shaft disposed in the shaft hole, the positioning baffle is provided in the chamber and provided with a first baffle corresponding to an embedding groove of the seat, and a second baffle corresponding to the accommodating groove and the groove, and the retaining ring is embedded in the ring groove.

A disc tumbler cylinder lock has a lock cylinder base, multiple discs, and multiple gaskets. The lock cylinder base has an accommodating space, a position limiting opening, and an accommodating opening. Each of the discs has a position limiting protrusion and a disc notch. Each of the gaskets has a ring body, a position limiting segment, and a rotation limiting segment. The position limiting segment protrudes outward from an outer annular surface of the ring body along a radial direction. The rotation limiting segment protrudes from the position limiting segment along an axial direction of the lock sleeve. The discs and the gaskets are staggeredly accommodated in the accommodating space. A side surface of the position limiting protrusion abuts a side surface of the position limiting opening. Two sides of the position limiting segment abut two opposite sides of the position limiting opening.

A padlock including a shackle having a short leg and a long leg, a lock body having a first hole configured to receive the short leg of the shackle, and a second hole configured to receive the long leg of the shackle, where the long leg is configured to at least partially remain within the lock body, a latch movable between a first position engaged with the short leg of the shackle and a second position disengaged from the short leg of the shackle, a cylinder configured for rotational movement within the lock body and operatively engaged with the latch, a sleeve configured to control rotational movement of the cylinder, and wherein when the latch is in the first position the padlock is in a locked mode, and when the latch is in the second position the padlock is in an unlocked mode.

A lock for pick prevention includes a set of cylinder pins aligned in a row in a cylinder. A first set of security pins are in a first carriage assembly. The security pins are aligned to a keyed displacement in cooperation with the set of cylinder pins. A second carriage assembly is positioned angularly displaced from the position of the first carriage assembly. One of the second set of security pins is aligned to the same keyed displacement as a corresponding one of the first set of security pins. An obstructive device is coupled to the second set of security pins, which is disposed to obstruct the cylinder from reaching an unlocked position in the event, a displacement of the second set of security pins does not align with the same keyed displacement as the first set of security pins.

The invention relates to a mechanical system for blocking and opening in a lock that can be actuated via a key with a linear movement, without rotation, which does not therefore require a rotation of the key to actuate the opening mechanism, not including any kind of cylinder system. Same comprises two complete parts, as shown in FIG. 1, a special key (1) and the system comprising the set of parts forming the lock. Upon introducing the key with a simple linear movement, and without needing to rotate same, the different mechanical actions are triggered that permit the unblocking of the lock, such that the individual notches of the key press on readers (2), which are to be calibrated, and, only if the position is correct, the mechanisms permitting the opening are released. Same is particularly applicable in embedded locks for all door configurations.

A disc tumbler lock assembly includes a lock cylinder inserted in a lock cylinder chamber of a lock housing, the lock cylinder being formed with a disc cavity and a lug groove; inner locking discs each having a first key hole with a first locking tooth therein, a side of each inner locking disc being formed with a first latch notch and a first lug located in the lug groove; outer locking discs each having an inner locking disc room and a second key hole with a second locking tooth therein, a side of each outer locking disc being formed with a second latch notch and a second lug located in the lug groove; the inner and outer locking discs being arranged in pairs, a corresponding one of the inner locking discs being disposed in the inner locking disc room of a corresponding one of the outer locking discs.

The present invention provides a structure composed of lock core and key, which lock pieces may only shift in parallel, so as to avoid the lock pieces from rotating and to prevent the key sockets on the lock pieces from misaligning with one another due to random rotation of the lock pieces, which ensures easy and smooth key insertion and operation.

An interchangeable cylinder lock core with a mechanism for transferring a torque to a lock unit when a key plug is rotated. The interchangeable cylinder lock core includes a shell having an upper part, provided with a central row of locking pins in associated cavities, and a lower part with a cylindrical bore accommodating the rotatable key plug. At least a part of the cylindrical bore extends through a rotatable retainer sleeve. A back region of the key plug has a minimum length with the adjoining front region of the key plug being located in front of the mechanism for transferring torque. The adjoining front region accommodates, in addition to the central row of locking pins, at least one side locking mechanism which is located in its entirety within the front region of the key plug and interacts with at least one recess in a fixed front end sleeve portion.
