A core replaceable hockey lock includes a first end face and a second end face. The first end face includes a first cavity, a second cavity, a third cavity and a fourth cavity. The end face includes a core hole which communicates with the second cavity. A lateral hole is defined radially in the lock and communicates with the first and fourth cavities. A locking member is located in the second cavity and includes a connection portion connected to the transmission portion, and a stop plate which slides in the third cavity when the locking member is rotated. A locking part is located in the fourth cavity. A shackle is located in the lateral hole and includes a neck located corresponding to the fourth cavity and the locking part. The first cavity and the core hole are parallel to each other. The core is replaceable by removing the cover.

Door lock shielding cover, which includes a shielding cover body, an attraction member, and blocking portions. The shielding cover body is configured to be movably installed onto a lock panel of a smart door lock. The attraction member is installed on a side of the shielding cover body adjacent to the lock panel of the smart door lock. A plurality of through holes is defined in the attraction member. The blocking portions correspond to the through holes in a one-to-one manner. Each of the blocking portions is fixed to the shielding cover body through a connecting portion that penetrates the through hole, thereby fixing the attraction member to the shielding cover body. The fixing between the shielding cover body and the attraction member in the door lock shielding cover is firm and durable.

A lock assembly for a door includes a lock mechanism moveable between an extended position wherein the door is locked and a retracted position wherein the door is unlocked such that the door may be opened and closed. The lock assembly also includes first and second lock cylinders operably connected to the lock mechanism such that actuation thereof causes the lock mechanism to move to the retracted position, the lock cylinders each including a first keyhole. A tamper resistant member is moveable between a protected position in which the keyhole of the second cylinder is inaccessible and an unprotected position in which the keyhole of the second cylinder is accessible, such that a tool is required in order to move the tamper resistant member from the protected position to the unprotected position, the tool adapted to be stored separately from the door.

An electronic ball lock is disclosed, including: a front ball lock body, where the front ball lock body includes a front fixed frame and a front sleeve rotatably arranged on the front fixed frame; a rear ball lock body; a connecting rod having one end connected with the rear ball lock body and the other end provided with a driving member extending into the front fixed frame; an electric clutch mechanism arranged in the front fixed frame and capable of driving the front sleeve to be coupled with or separated from the driving member; and an identification module arranged on the front ball lock body and electrically connected with the electric clutch mechanism.

A lock can include attack-resistant and/or weather-resistant features. Attack-resistant features can include a sacrificial link between a locking mechanism and an external keyway covering an exterior face of the locking mechanism. The sacrificial link can break during a torque attack on the lock such that the full force of the torque attack is not applied to the locking mechanism. Weather-resistant features can include drain openings in one or more housing components external to the locking mechanism to facilitate drainage of liquid matter from the lock before the liquid matter reaches the locking mechanism.

A locking device includes a stator, with a rotor, and with an anti-pull-out device for preventing a key from being pulled out over a rotational angle range, wherein the anti-pull-out device can be moved into a first position and into a second position, wherein the anti-pull-out device has an elastic design, wherein the elastic effect forces the anti-pull-out device into the second position. The anti-pull-out device has a bent annular region for operatively connecting to the key, wherein the bent annular region includes at least one gap in the first position for introducing a key, wherein in the second position of the anti-pull-out device, the gap is modified such that the key is prevented from being inserted or from being pulled out.

A handle for a vehicle door includes a cover member configured to be secured to a bracket. The cover member includes an access part to a mechanical lockset, the access part having an opening through which the mechanical lockset can be accessed, defining an opening axis passing through the opening, and a cover element configured to be movable between a locked position and an unlocked position, so that when in the unlocked position, the cover element can be moved away from to the opening such that the mechanical lockset can be accessed. The cover element is configured to be moved from the unlocked position to the unlocked position by rotating the cover element with respect to the access part according to the opening axis.

A delayed return mechanism, such as for a door latch, including a housing having a hole with an axis, a cavity in the housing at least partially filled with a fluid media, a hub disposed in the cavity including a spindle hole coaxial with the hole in the housing including teeth within the spindle hole to engage a spindle, the hub being rotatable about the axis and having a fin extending radially outward in the cavity, and a channel through which the fluid media passes during rotation of the hub to control flow of the fluid media about the cavity.

A lock includes a housing in which a combination lock is received. The combination lock is unlocked when the combination unit of the combination lock is located at an unlocked position. The combination lock has a cam pin which is operated when the combination lock is unlocked and locked. A button is pushed to drive a cam which is located beside the combination lock. When the combination lock is locked, the cam pin is connected to the restriction hole to restrict the cam, and the latch is in its locked status. When the combination lock is unlocked, the cam pin is removed from the restriction hole. When the button is pushed, the cam is rotated to release the latch from the room of the housing. The combination of the combination lock can be changed by operating the operation bar when the combination lock is unlocked.
