The effect of the connecting parts of special screws on doors and windows

The metal parts of the special screw are the parts that are responsible for sticking to the door and window frames and fans. Without its existence, the doors and windows will only become dead fans, losing the meaning of the doors and windows. Then, let's understand the effect of the connecting parts of the special screw on the doors and windows!

1. The physical performance indexes of doors and windows are wind pressure resistance, air tightness, water tightness, heat preservation, heat insulation, sound insulation and wind pressure resistance.

When the inner casement window is under normal wind pressure; Due to the force of the hardware buckle, try to use more buckle forms. The more the capture, the smaller the force exerted by each capture pair, and the smaller the deformation. When the inner casement window is under negative pressure: the frame is stressed. When the outer casement window is compressed: because the buckle will be stressed, it should be in the form of multiple buckles. The more the capture, the smaller the force exerted by each capture pair, and the smaller the deformation. When the outer casement window is under normal wind pressure: the frame is stressed.

It can be seen from the above special screws that hardware tools act on a performance of doors and windows-wind pressure tolerance, which determines the success or failure of doors and windows; similarly, air tightness, water tightness, heat preservation, heat insulation, and sound insulation are related to hardware The door and window sealing is related. The buckle and lock stations of the accessories are distributed around the entire door and window. After the doors and windows are locked, the buckle and the locking table are firmly tied together and matched with the hinge (hinge) or sliding bracket to generate a strong sealing pressing force, which elastically deforms the sealing strip and provides sufficient sealing performance for the doors and windows, thus the fan and the frame are the same, and the opening and closing requirements such as the mechanical performance index (opening and closing force, repeated opening and closing) of the doors and windows cannot be separated from the requirements of the hardware.

2. Doors and windows are light components, and their energy consumption accounts for more than half of the energy consumption of the real estate. It is important in the energy saving of the real estate. The energy saving of the doors and windows should be fully considered in the design, that is, the heat preservation and heat insulation. If there is no multi-point locking metal parts, no matter how well the doors and windows are done, heat preservation and heat insulation can be considered.

Similarly, the anti-theft performance of doors and windows is also a concern of the owners. In this regard, the anti-theft performance of accessories plays an important role in the development of components of intelligent anti-theft doors and windows.

4. Doors and windows have a variety of window shapes and structural forms. The functions of special forms and special threaded window shapes depend on the configuration of hardware accessories. If there is no metal fitting, how can the hanging window be flattened or turned inward? In the process of folding the window frame, how to realize the function of the window frame and folding? Is it possible to achieve the unique and specific function through the function of the accessories, such as the inverted and movable shutters!
