We are a window hardware manufacturer, mainly producing hardware doors and windows. What is the role of door and window hardware?
When the inner casement window is under positive wind pressure; the hardware lock points are stressed, so multiple lock points should be adopted. The more locking points, the smaller the force applied by each locking point to the middle leg, and the smaller the relative deflection of the deformation.
When the inner casement window is under negative pressure: the frame is stressed.
When the outer casement window is under pressure: the locking point is stressed, so multiple locking points should be adopted. The more locking points, the smaller the force applied by each locking point to the middle leg, and the smaller the relative deflection of the deformation.
When the outer casement window is under positive wind pressure: the frame is stressed.
It can be seen from the above that the role of hardware accessories on the first performance of doors and windows, wind pressure resistance, determines the success or failure of doors and windows; similarly, air tightness, water tightness, heat preservation, heat insulation, and sound insulation are all involved in doors and windows with hardware accessories. Sealing is concerned. Hardware fitting lock points and lock seats are distributed around the entire door and window. When the doors and windows are locked, the lock points and the lock seat are firmly buckled together, and cooperate with the hinge (hinge) or sliding brace to generate a strong sealing pressure and elastically deform the sealing strip, thereby providing enough for the door and window The sealing performance of the fan and frame can greatly improve the performance of doors and windows. If there are no multi-point lock hardware accessories, no matter how well the doors and windows are made, the heat preservation and heat insulation can be imagined. Similarly, door and window folding mechanical performance indicators (opening and closing force, repeated opening and closing), and other opening and closing requirements are also inseparable from the requirements of hardware accessories.
In addition, we also provide door handle production, therefore, we are also known as door handle manufacturers.
