The different components of anti-theft doors play important roles:
1、 Door panel
1. Protective function:
      It is the main part of the anti-theft door, usually made of steel plate or other sturdy materials. The thickness and material of the door panel determine the protective ability of the anti-theft door, which can effectively block external impact, lock picking, and violent opening.
      It can resist the damage caused by thieves using tools such as hammers, pry bars, etc., providing the first line of security for homes and property.
2. Sound and heat insulation:
      It has certain sound insulation and thermal insulation properties, which can reduce the interference of external noise and create a quiet indoor environment. At the same time, it can prevent cold air from entering in winter and hot air from entering in summer, playing a role in energy conservation and insulation.
2、 Door frame
1. Fixation and support:
      The door frame is the basic framework for installing anti-theft doors, which fixes the door panel to the door opening and provides stable support for the entire door. The strength and installation quality of the door frame directly affect the stability and safety of the anti-theft door.
      Ensure that the door will not deform or loosen during use, and guarantee the normal opening and closing and sealing performance of the door.
2. Sealing function:
      There is usually a sealing strip between the door frame and the door panel, which can effectively prevent dust, rainwater, air, etc. from entering the room. Good sealing performance can improve indoor comfort and reduce energy consumption.
3、 Locks
1. Security protection core:
      It is one of the important components of anti-theft doors, providing the main security protection function. High quality locks adopt excellent lock core technology, such as multi lock points, anti pry lock cores, password locks, fingerprint locks, etc., which can effectively prevent illegal opening.
      Multi lock point design can increase the firmness of the door, making it difficult for thieves to enter the interior by prying or forcefully opening the lock.
2. Convenient to use:
      At the same time, locks also need to have convenient features such as easy operation, quick unlocking, and easy key management. Some smart locks can also be remotely controlled through mobile apps, providing users with a more convenient user experience.
4、 Hinge
1. Connection and rotation:
      A hinge is a component that connects a door panel and a door frame, allowing the door to open and close smoothly. The quality and quantity of hinges determine the load-bearing capacity and service life of the door.
      A good hinge can withstand the weight of the door, ensuring that it will not sag or deform during long-term use, while also ensuring that the door opens and closes flexibly and freely.
2. Safety assistance:
      Some hinges also have anti pry function, which can increase the safety of the door. For example, hinges with anti pry nails can prevent the door panel from being pried open when the door is impacted by external forces.
5、 Cat's Eye and Doorbell
1. Observation and communication:
      Cat's eyes allow people indoors to observe the situation outside the door without opening it, improving safety. The doorbell facilitates communication between visitors and hosts, enabling indoor and outdoor communication.
      Modern cat eyes and doorbells often have additional features such as night vision, photography and video recording, further enhancing safety and convenience.
2. Safety warning:
      Some smart cat eyes can be connected to mobile phones, and when someone stays outside the door for a long time or encounters abnormal situations, they will send alarm messages to the owner, allowing them to timely understand the situation outside the door.
6、 Sealing strip
1. Sealing and sound insulation:
     The sealing strip is installed between the door frame and the door panel to provide sealing and sound insulation. It can effectively block the entry of dust, rainwater, air, and noise, improving the indoor environmental quality.
     Good sealing performance can reduce energy consumption and lower heating and cooling costs.
2. Buffer and shock absorption:
     The sealing strip can also serve as a buffer and shock absorber, reducing the impact force when the door is closed and protecting the door and frame from damage. At the same time, it can also reduce the noise when closing the door and create a quiet living environment.
