Abstract: A door lock device is provided and includes: a housing, an acting assembly arranged in the housing and having a lock tongue, an operating assembly arranged in the housing and interlocked with an outdoor handle, and a regulating assembly arranged in the housing for a user to regulate the operating assembly into an interlocking state or an idle state. As such, in the interlocking state, the outdoor handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and in the idle state, the operating assembly cannot drive the acting assembly and the outdoor handle cannot be interlocked with the lock tongue.

Abstract: A lock assembly is provided and includes: a driving member; an acting member connected to the driving member; an active member cooperating with the acting member for operation; and a main lock member interlocked with the active member. The driving member drives the acting member to swing and the acting member touches the active member so as to displace the active member and synchronously displace the main lock member. Therefore, the lock assembly is buried in a door frame through cooperation of the driving member, the acting member and the active member, so as to be protected from being damaged or stolen.

Abstract: A door lock device for emergency doors is provided, in which, through a configuration of a sensing component, the actuating time can be adjusted by a driver according to demands to facilitate time-delayed unlocking.

Abstract: A pneumatic hammer includes a piston in an operating cylinder; and a valve mounted at a rear end of the operating cylinder and including a front mechanism, a rear mechanism, and a disc. The rear mechanism includes two opposite inlets, a chamber member, outlets, a relief chamber communicating with the outlets, two opposite inlet channels disposed externally of the chamber member, and two first outlet tunnels disposed externally of the chamber member. The front mechanism includes a chamber element on one surface communicating with the inlet channels, an axial tunnel through a center of the chamber element, and two second outlet tunnels disposed externally of the chamber element. The disc is between the chamber member and the chamber element. The operating cylinder includes intermediate through holes and two inlet passageways having one ends communicating with the axial space and the other ends communicating with the second outlet tunnels.

Abstract: Provided is a door lock, including at least one latch portion, and a controlling portion for actuating the latch portion. The controlling portion includes a base having a configuration hole and a linkage assembly disposed on the base. The linkage assembly includes an actuating member movably disposed on the base, a driving member connected to the actuating member, a sliding member connected to the driving member, disposed on the base and having at least one opening, and a connecting member connected to the sliding member and the latch portion for enabling the sliding member to drive the connecting member and actuate the latch portion and exposing the configuration hole from the opening when the actuating member drives the driving member to actuate the sliding member. When the door lock is repaired, the screw thread can be set in the configuration hole from the opening without removing the linkage assembly.

Abstract: A fire door lock is provides. A first opening unit is installed in a fire door panel to move a door locking bolt. A second opening unit laterally located on the fire door has a pressing handle coupled with an actuating block for operating the locking bolt. When the pressing handle is pushed and pressed, the actuating block activates an actuating rod and a linking arm to move horizontally. One end of the linking arm is coupled to a driving lever which is induced by the linking arm to swing. One end of the driving lever has a pulley extending into the first opening unit to activate a locking bolt base connected to the locking bolt to move horizontally. The locking bolt is accordingly adapted to extend from or retract into the first opening unit in a horizontal direction to facilitate the release or engagement of the lock.
