A door-and-window system having a handle component (), a transmission component () and a force receiving portion (). When the handle component () is operated, the force receiving portion () moves along a first guide groove () via the transmission component (), and at the same time a driving portion () moves along a second guide groove (). Due to a relationship between a guide member () and a third guide groove (), a first base seat () translates relative to a second base seat () along a direction of the third guide groove (), such that a movable door-and-window () can abut tightly against or move away from a sealing member () on a door-and-window mounting profile ().

An eccentric hinge includes a rail, a stop block arranged on a first end of the rail, a fixing rod parallel with the rail, a sliding block, a connecting rod and a transmission rod, where the sliding block is arranged on the rail; a first end of the connecting rod is connected with a second end of the rail; a second end of the connecting rod is connected with the fixing rod; a first end of the transmission rod is connected with the sliding bock; a second end of the transmission rod is connected with the connecting rod; when the eccentric hinge is in a closed state, a first centerline of the fixing rod and a second centerline of the rail are parallel lines in a same plane; and a distance between the parallel lines is greater than 0 mm and less than or equal to 10 mm.

Eccentric hinge

The present invention is applicable to the field of door and window technologies, and provides a top-hung casement window, including a window frame, a casement sash, and a hinge assembly. The hinge assembly includes a first hinge, a second hinge, a pivot, a connecting piece, a swing part, and a vertical limiting part. During the turning of the casement sash, the swing part swings only around the vertical limiting part, with a limited motion space. Therefore, the swing part and the casement do not shake easily. When the casement sash is open, the position of the vertical limiting part and casement sash does not change. Because all force of gravity of the casement sash is transferred to the window frame through the vertical limiting part, the bottom of the casement sash does not rub the window frame, avoiding generation of noise and abrasion of components of the hung window.

Top-hung casement window

A method and a device for time synchronization are disclosed according to the embodiments of the present invention. The method includes: selecting, by a slave device, a port of a single-fiber bi-directional line as a synchronization port of a 1588 clock protocol; specifying a work mode of the synchronization port; exchanging a 1588 clock synchronization packet with a master device through the synchronization port according to the work mode; acquiring transmission time information and restore a system clock according to the 1588 clock synchronization packet; and adjusting the system clock according to the work mode and the transmission time information. The device includes: a line processing module, a clock recovery module and a clock adjustment module. Through the method and the device, zero-error time synchronization is implemented; and in the case of unfixed path delay, the time synchronization can also be implemented.
