A combination padlock comprising a body, true gates, a locking ball, a spindle and a plurality of clutches and dials, a shackle which contains a neck, a locking bolt with a neck, the spindle to control the lock opening of the locking bolt and control the alignment of the true gates of the clutches, the plurality of clutches to prevent the lock from being opened when the dials are not in a locked opened combination, the clutches having extended fins with rounded edges, and the plurality of dials to control the rotational movement of the clutches, so that when the extended fins of the clutches are fully aligned with the true gates, a user can pull a knob-side of the spindle to the right so that the neck of the shackle forces the locking-ball to move upward away from the neck of the shackle so as to unlock the padlock.

An exemplary lock apparatus generally includes a shackle, a crossbar, a lock device, a first bolt, and a trigger. The lock device has a locked state in which the lock device retains a spindle in a spindle locking position, and an unlocked state in which the lock device does not prevent movement of the spindle to a spindle unlocking position. The first bolt is engaged with the spindle such that movement of the spindle between the spindle locking position and the spindle unlocking position drives the first bolt between a first locking position and a first unlocking position. The trigger is movably mounted in the crossbar for movement between an engagement position, in which the trigger maintains the spindle in the spindle unlocking position, and a disengagement position, in which the spindle is operable to move to the spindle locking position.

A tamper resistant hasp having: a first member extending between a first inner end and a first outer end, the first member defining a first member outer boundary and has a mounting aperture located within the first member outer boundary; a second member that has: a first portion that extends between a second inner end and a joint end, the second inner end being pivotally coupled to the first inner end, the second member pivots relative to the first member so that in a first pivot position the first portion is against the first member and covers the mounting aperture, and in a second pivot position such that the mounting aperture is uncovered; and a second portion that extends away from the first portion at the joint end to a third end and having a shackle aperture located within the second portion outer boundary.

A lock device includes a lock body that includes a bottom portion and a top portion. The lock body is formed, in the interior thereof, with a first accommodation zone, a second accommodation zone, a lock bore, a protective cover lid, a lock core, and a closure plate. The lock device includes a shackle that is deeply hidden inside the lock body and is thus protected from being damaged. A lock core is disposed into the lock body from the bottom portion, so that the lock core is arranged, in an upstanding manner, inside the lock body, and a keyhole of the lock core faces the top portion of the lock body to allow the keyhole to be readily found for conducting an unlocking operation. The lock core is protected by a protective cover lid from being easily destructed.

A padlock shroud is described for protecting a padlock. For example, one implementation of a padlock shroud comprises: a shroud body having a chamber with an opening accessible to a padlock body, the opening formed in a lower portion of the shroud body, wherein to engage a padlock with the shroud, the padlock body is inserted into the chamber through the opening, apertures formed through an upper portion of the shroud body and having a spacing substantially equal to a spacing of legs of a shackle to be engaged with the padlock through the apertures, a shackle protector having first and second connection points adjacent to the apertures and extending upward from the upper portion of the shroud body at a length at least substantially equal to a length of the legs of the shackle, and a press pin aperture formed on a side of the shroud body and positioned to allow a press pin to be inserted beneath the padlock body when the padlock body is fully inserted into the chamber.

A hoop lock comprises a lock body and a hoop which is lockable to the lock body. The hoop comprises a metal tube having a cavity extending in a longitudinal direction of the tube. In the cavity is a reinforcing filling. At least one hoop end comprises a locking structure for a locking engagement with a locking device of the lock body. The locking structure is formed at an outer side of the tube without forming an opening to the cavity of the tube.

The present disclosure provides an intelligent lock. In an embodiment, the intelligent lock includes: a lock body having a lock hole; a lock lever, the lock lever being capable of being plugged into and being unplugged out of the lock hole of the lock body; a first restricting member movably provided inside the lock body, and capable of being moved and latched into the lock hole to restrict the plugging of the lock lever into the lock hole or the unplugging of the lock lever out of the lock hole; a second restricting member movably provided inside the lock body, and capable of being abutted against the first restricting member so as to restrict a movement of the first restricting member; a detecting device provided in the lock body, and configured to detect the plugging operation of the lock lever into the lock hole or the unplugging operation of the lock lever out of the lock hole and to send a detection signal; and a main control element communicatively connected to the detecting device, and configured to determine a locking state of the intelligent lock in accordance with the detection signal sent by the detecting device.
