    • A padlock comprising a lock body; a U-shaped lock hoop that has a circular cross-section, that is displaceably held at the lock body between a closed position and an open position, and that has a first hoop limb and a second hoop limb that is longer than the first hoop limb; and a locking device in the lock body for locking the lock hoop to the lock body in the closed position of the lock hoop. The locking device comprises at least one latch element and can be adjusted between a locked position, in which the latch element engages into an engagement recess in the closed position of the lock hoop, said engagement recess being formed in a flank of the second hoop limb facing the first hoop limb, and an unlocked position in which the latch element is located outside the engagement recess. In the second hoop limb, a peripheral groove is formed which is located closer to the free end of the second hoop limb than the engagement recess and into which the latch element engages in the open position of the lock hoop. The second hoop limb has a passage that extends between the free end of the second hoop limb and the peripheral groove and that has a surface that is recessed with respect to the circular cross-section of the lock hoop. The second hoop limb receives a blocking element between its free end and the peripheral groove, said blocking element projecting over the recessed surface of the passage in order to prevent, in the open position of the lock hoop, a passing of the latch element through the passage, starting from the peripheral groove.

    • The present invention discloses an electronic key storage case, comprising a housing, a cavity defined in the housing and configured for storage, a front panel configured for password input and disposed on the front of the housing, a locking mechanism and a control circuit disposed on an inner side of the front panel, characterized in that, the locking mechanism is an electronic lock, and comprises a driving circuit, a lock tongue, and a mounting assembly connected with the lock tongue, the driving circuit is configured to receive unlocking information from the control circuit and control an action on the lock tongue, the mounting assembly comprises a lock bracket, a rotating shaft located on the lock bracket, and a locking hook spring disposed on the rotating shaft, a locking hook groove is provided on the lock tongue, and the lock tongue is matched with the locking hook spring through the driving circuit, to obtain a degree of freedom of rotating forward or reverse rotation with the rotating shaft as a central axis to form two states of the locking hook groove engaged with or separated from the locking pin. In the present invention, the key case is opened automatically in an electronic lock manner, thereby being easier to use, providing a securer lock structure, and avoiding undesirably opening.
