A direct swing leaf actuator for actuating a swing leaf of a door includes a receiving box for arrangement in or on a stationary part of the leaf system or of a building having the leaf system, and includes a driven shaft, which interacts with an actuator unit, wherein a swing leaf can be placed on the driven shaft in a torque-transmitting manner. A device is present for adjusting the spatial position of the driven shaft relative to the receiving box. The device has an adjusting frame with a height-adjusting unit, wherein the adjusting frame is arranged in the receiving box and the driven shaft is received on the adjusting frame so as to be height-adjustable using the height-adjusting unit.

A rotating coupling system for a closing element, such as a door, window, door or the like, and a stationary support structure, such as a wall, floor, frame or the like includes a hinge device anchorable to the closing element and a mounting plate anchorable to the stationary support structure. The hinge device has a hinge body and a pivot defining a first axis, and are coupled each other to rotate one with respect to the other around the axis. In particular, the pivot includes a coupling portion, which protrudes from the hinge body, and the mounting plate includes a plate-shaped body having a seat that receives the coupling portion of the pivot. The plate-shaped body further includes an adjusting member to adjust its position with respect to the stationary support structure.

The clamping assembly for a glass door includes an outer clamping body, an inner clamping body, an automatic homing mechanism and a positioning unit. An upper jaw for clamping the glass door is provided on the top of the outer clamping body, and a first side wall and a second side wall are recessedly formed at the bottom of the outer clamping body. A first lower jaw is formed between the first side wall and the second side wall. The inner clamping body is disposed in the first lower jaw. A second lower jaw is formed at the bottom of the inner clamping body. The automatic homing mechanism is disposed in the second lower jaw. The positioning unit penetrates the first side wall to abut against the first recess on the inner clamping body.

A rotary buffer capable of adjusting damping includes a shaft sleeve, a rotating shaft, two oil valve plates, and an adjusting nut. An outer wall of a spindle is provided with wing plates. A left curved surface and a right curved surface of the spindle are arranged in a symmetrical and interlaced manner to form an oil gap. Each wing plate is mated with a corresponding one of the oil valve plates. Two sides of each wing plate are provided with pressure regulation passages communicating with an inner cavity of the shaft sleeve and an outer end face of a supporting shaft. The adjusting nut is provided with a platform surface to get contact with the outer end face of the supporting shaft for sealing the pressure regulation passages.

The present invention discloses a spindle with speed adjustment and automatic return device, included set up one resilient component, one cylinder, also one spindle and one cam of the same spindle on a base, between the cam and the resilient component set up one slider component, and one first rack set up on the slider component, both side of the cylinder set up with one cylinder rod and one flow adjustment valve, and one second rack set up on the cylinder rod, one gear set meshed in between the first rack and the second rack; the cam can follow spindle rotation and drive slider component move to the resilient component, to bring the first rack through gear set to drive the cylinder rod by the second rack, to make the cylinder through flow adjustment valve to suck the medium.
