Abstract: A door opener capable of controlling the door closing speed includes a driving device and a generator mode operating module electrically connected to the driving device. The driving device includes a motor which can be supplied with power to pivot a door from an open position to a closed position. The driving device detects the position of the door by a switch. When pivotal movement of the door is achieved without supplying power to the door, the pivotal movement sets the generator mode operating module to a generator mode or a non-generator mode. In the generator mode, the motor is impeded by the electromagnetic resistance, such that the pivoting speed of the door is reduced. In the non-generator mode, the motor is not impeded by the electromagnetic resistance, such that the pivoting speed of the door is increased.

Abstract: A door opener includes a driving device having a first transmission member driven by a motor. A push rod is connected to the first transmission member to move therewith. A pressing rod unit is pivotably coupled to the push rod and includes a coupling sleeve, first and second end pieces coupled to the coupling sleeve, and an adjusting screw rod in threading connection with the second end piece. The first end piece is coupled with a first pivotal member coupled with a door. An end of the adjusting screw rod is located outside of the coupling sleeve and is coupled with a second pivotal member pivotably connected to the push rod. When the adjusting screw rod rotates, the adjusting screw rod moves in an axial direction of the coupling sleeve to change a length of a portion of the adjusting screw rod outside of the coupling sleeve.

Abstract: A door opener with an anti-loose linking unit includes a driving device and a linking unit disposed between the driving device and the door. The driving device includes a motor and a first transmission member operatively connected to the motor. The linking unit includes a first push rod connected via a connecting screw to the first transmission member, permitting joint pivotal movement. An anti-loose member is non-rotatably mounted on the first push rod. Ahead of the connecting screw is non-rotatably coupled with the anti-loose member. Thus, the connecting screw cannot rotate relative to the first transmission member and the first push rod, reliably preventing the first push rod from disengaging from the first transmission member.

Abstract: A driving device for a door opener includes a motor driving a first transmission member to rotate. Rotation of the first transmission member causes lateral displacement of a sliding member which moves jointly with a connecting rod. A return spring is mounted around the connecting rod. An adjusting ring is in threading connection with the connecting rod and abuts against the return spring. When the first transmission member does not rotate, rotation of the adjusting ring causes displacement of the adjusting ring in the lateral direction to change an extent of pre-compression of the return spring. When the first transmission member rotates in a direction, the connecting rod and the adjusting ring together move in the lateral direction towards the first transmission member, and the return spring is compressed. When the first transmission member rotates in a reverse direction, and the return spring restores its length.

Abstract: A door lock with a reinforced fireproof effect includes a lock body mounted on a door and inner and outer operating units mounted to two sides of the door, respectively. The lock body includes inner and outer chassis made of ferrous material or stainless steel having a melting point higher than 1300° C. Inner and outer fixing members coupled with the inner and outer chassis are also made of ferrous material or stainless steel. Thus, these components of the door lock are less likely to melt during a fire, reducing the spreading speed of the fire.

Abstract: A door opener includes a first side cover fixed to a mounting seat. A mode switching device is disposed on the first side cover and includes an anti-theft control module. A driving device is operatively connected to a door for moving the door. A control device is electrically connected to the mode switching device and the driving device. The control device includes a control panel for operating the driving device. The mode switching device is switchable to a wake-up mode only when the anti-theft control module is unlocked. The driving device is operable by the control panel only when the mode switching device is in the wake-up mode. An outer cover is coupled to the first side cover and covers an outer side of the driving device and an outer side of the control device. The control panel is exposed via a window of the outer cover to permit operation.

Abstract: A door opener includes a mount seat having a bottom wall. A reinforcing seat is fixed to the bottom wall. A driving device for opening or closing the door is detachably coupled to the reinforcing seat and includes a motor. A quick-release device includes a quick-release seat fixed to the bottom wall and having a first coupling portion. The quick-release device further includes a movable member slidably coupled to the quick-release seat and having a movable coupling portion. A control device includes a protective housing and a control panel coupled to the protective housing. The protective housing is detachably coupled with the first coupling portion and the movable coupling portion. The driving device is selectively mounted to make the motor face or face away from the control device. An outer cover covers the driving device and the control device and includes a window in which the control panel is located.

Abstract: A latch guiding and coupling device includes a coupling seat having first and second sides. An insertion groove is defined between the first and second sides and extends from a first surface through a second surface of the coupling seat. A recessed portion is formed in the first side and rotatably receives a roller. Each of two ends of the recessed portion has a positioning groove extending to the first surface to form a notch. An axle extends through the roller and includes two ends respectively received in the positioning grooves. A locking plate is mounted to the first surface of the coupling seat. The locking plate includes an opening aligned with the insertion groove and two stopper portions aligned with the positioning grooves. Each stopper portion covers one of the notches to prevent the axle from disengaging from the positioning grooves. The roller protrudes beyond the locking plate.

Abstract: An electric door lock includes an operating device and a latch device operably connected to the operating device.
