As we all know, hardware accessories can be called the heart of doors and windows, doors and windows full of all performances such as wind pressure resistance, air tightness, water tightness, heat preservation, heat insulation, sound insulation, etc., are closely related to hardware accessories.

Hardware lock points and lock seats are distributed around the entire door and window. When the door and window are locked, the lock point and the lock seat are firmly fastened together, and cooperate with the hinge or the sliding support to jointly generate a strong sealing pressing force, so that the sealing strip is deformed by force, thereby providing sufficient sealing performance for the door and window. Forming the fan and the frame together can greatly improve the performance of the door and window.

At the same time, doors and windows are lightweight components, and their energy consumption accounts for more than half of the building energy consumption, which is the top priority of building energy conservation. When designing, we must fully consider the energy-saving problems of doors and windows, namely insulation and heat insulation. If there are no multi-point lock hardware accessories, the doors and windows do a good job, and its insulation and heat insulation performance will not be ideal.

The anti-theft performance of doors and windows is also a key issue. The anti-theft performance of hardware accessories, especially in the development of intelligent security doors and windows components, the anti-theft performance of hardware accessories is playing an important role.

1. stainless steel handle and stainless steel other "hardware" can be scrubbed with brightener to increase the brightness.
2. If the door and window switch makes a sound, it is necessary to regularly drain some lubricating oil on the hanging wheel every 2-3 months to ensure the lasting smoothness and smoothness of the pulley.
3. there are hinges, hanging wheels, casters and other moving parts, in the long-term movement may be due to the adhesion of dust to reduce the function, you can point one or two drops of lubricant to make it smooth.
4. When the lock cylinder is not sensitive, a small amount of black powder can be scraped from the pencil lead and lightly blown into the lock hole. This is because the graphite component in between is an excellent solid lubricant. Never drop in the oil, which will make it easier to stick to the dust.
5. It is necessary to pay attention to the direction of the handle rotation, avoid using dead force. In particular, teach children not to hang on the door handle, which is both dangerous and dangerous to the inner door.
