The window opener can open the ventilation window at a higher position through a certain device, and the window opening executive component determines the width of the window, the weight of the window opener and whether it has a locking function. The angle connector is the transmission part, and its deformation determines the ability of the window opener to adapt to different window types and different installation conditions. The operating part can be in the form of a handle or a rocker. There is also a manual window opener, as long as the manual window opener is suitable for opening the window inside and outside.
Two, door closer
Door closers can be divided into three types: door bottom springs, door top door closers and floor springs. The main feature of the door closer is that it is slow when closing, and there is no collision sound after closing. It is suitable for the door of high-end hotel guest rooms. The door closer is divided into horizontal and straight types. The doors and windows are automatically closed after opening.
Three, hinge
There are two kinds of materials for the hinges: copper and stainless steel. In order to open the hinges easily and without noise when selecting the hinges, it is better to choose the ball bearings in the hinge shaft. When choosing, the brightness of the exterior paint and electroplating, the gap and strength of the bearing wheels determine the flexibility and noise of the drawer opening and closing, and the bearing wheels with wear resistance and even rotation should be selected.
Four, handle
The shape and color of the handle are varied, and the materials of the handle include copper, aluminum, stainless steel, ceramics, etc. The handles that are electroplated and painted by electrostatic spray are wear-resistant and anti-corrosion. In addition to matching the decoration style of the room, they should also be able to withstand greater pulling force to protect and keep the home in a safe state.
Five, latch
The so-called bolt is a set of pins used to fix the workpiece on the fixture or the mold. It is a simple component to prevent opening, and it is an anti-theft component to prevent doors and windows from being opened from the outside. The structure is much simpler than the lock, but it is locked outside the door and the latch is in the door.
