The anti-theft door components mainly include the door body, door lock, hinges, peephole, etc. The characteristics of each component are as follows:
1、 Door body
1. Diverse materials
There are multiple options for anti-theft door body materials. Steel door body is the most common type, which has high strength and hardness, and can effectively resist external impact. The thickness of the steel plate for a typical steel door body is between 0.8-1.5mm. This thickness of steel can withstand significant pressure and impact forces, providing good safety protection for indoor environments in the event of violent acts such as prying or smashing.
There is also solid wood composite material, which combines the beauty of solid wood with the strength of other materials for the door body. Its outer layer is made of solid wood, and the interior is filled with fire-resistant, soundproof and other materials, such as rock wool. The solid wood part has been carefully selected and processed, with beautiful textures that can match various home decoration styles. At the same time, the internal filling material can enhance the insulation, sound insulation, and fire resistance of the door body.
Aluminum alloy doors have the characteristics of light weight and corrosion resistance. Its surface can be treated by oxidation, electrophoresis and other processes to give the door different colors and luster. Moreover, the low density of aluminum alloy makes the door easy to install and operate, while also resisting wind and rain erosion to a certain extent, making it suitable for use in various climatic conditions.
2. Reasonable structure
The anti-theft door body usually adopts a frame structure. The frame is generally made of high-strength metal, such as steel door frames, which can provide stable support for the door body. The filling material inside the frame is tightly integrated with the outer panel, ensuring the integrity of the door body through special processes such as gluing, riveting, etc. This structure enables the door body to evenly distribute stress when subjected to external forces, avoiding excessive local deformation. For example, when a door is subjected to a side impact, a reasonable structure can distribute the impact force throughout the entire door, reducing the possibility of damage.
Some anti-theft doors also have reinforcing ribs installed inside the door body. These reinforcing ribs are usually made of metal and distributed in a certain geometric shape (such as a criss crossing grid) inside the door, further enhancing the door's ability to resist deformation.
3. High anti-theft performance
In order to improve anti-theft performance, the surface of the door is usually treated with special treatment. For example, some door surfaces have anti drilling and anti sawing designs. Using special alloy steel plates or adding hard coatings on the surface of the steel plates makes it difficult for ordinary drills and saws to damage them.
The coordination between the door body and the door frame is also crucial. A good anti-theft door will have a precise sealing structure, such as an embedded door frame design, where the door body can be tightly embedded into the door frame and multiple sealing strips are installed. This not only prevents dust and rainwater from entering the room, but also enhances anti-theft performance, making it difficult for pry tools to insert into the door gaps.
2、 Door lock
1. High security level
Anti theft door locks are generally divided into mechanical locks and intelligent locks. The A-class lock core in mechanical locks is relatively simple, while B-class and super B-class (C-class) lock cores have higher safety. The key shape of B-class lock cylinder is complex, generally consisting of double row pins or blade structures, with a large number of keys and a low mutual opening rate. The super B-class (C-class) lock core adopts a more complex blade and milling groove structure, which has a longer technical opening time and can effectively prevent technical unlocking. For example, the technical opening time of the super B-level (C-level) lock cylinder can reach more than 270 minutes, greatly improving the safety of the door lock.
Smart locks have multiple unlocking methods, such as fingerprint recognition, password input, card swiping, etc. Fingerprint recognition technology is getting better and better, using semiconductor fingerprint recognition sensors to identify the detailed features of fingerprints with high recognition accuracy. It also has live detection function to prevent false fingerprints from being turned on. In terms of password input, some smart locks use virtual space password technology, adding any number before and after entering the correct password. As long as the correct password is included in the middle, the lock can be unlocked, which can effectively prevent the password from being peeped.
2. Strong durability
Whether it is a mechanical lock or an intelligent lock, the lock body and tongue are carefully designed. The lock body is usually made of high-strength metal materials (such as stainless steel), which can withstand frequent opening and closing operations. There are usually multiple locking tongues with sufficient length and strength. For example, the locking tongue of some anti-theft doors can extend up to 2-3cm in length and adopt a bold design, which can firmly lock the door body when it is closed, preventing the door from being pushed open by external forces.
The electronic components of smart locks also have good durability. The internal circuit board has undergone moisture-proof, dust-proof and other treatments, and the battery life is constantly improving. For example, some excellent smart locks can last for 1-2 years using regular dry batteries, and will issue an alarm to remind users to replace the battery when the battery is low.
3. Good convenience
Smart locks excel in terms of convenience. Users can quickly unlock the door lock with their fingerprint without carrying a key, especially when holding items with both hands. And different unlocking methods can be set for multiple users, such as fingerprint unlocking for family members and temporary password unlocking for visitors.
Some smart locks also have remote control function. By connecting to a mobile app, users can remotely check the status of door locks, such as whether they are open or if someone is attempting to open them illegally. When guests visit, they can also send a one-time password through the mobile app to enter the room.
3、 Hinge page
1. Strong load-bearing capacity
Anti theft door hinges are generally made of high-strength metal materials, such as stainless steel or thickened cold-rolled steel. They can withstand the weight of the door and remain stable during frequent opening and closing of the door. For example, for a heavy steel anti-theft door, hinges can ensure that the door body does not sag or deform during the opening and closing process. Generally speaking, excellent anti-theft door hinges can withstand a door weight of 100-200kg.
The core part of the hinge is the key structure. Its diameter is large and the material is hard, which can effectively disperse the pressure generated when the door is opened and closed. In terms of design, some hinges use ball bearing structures to reduce friction, making the door open and close more smoothly, while also improving the load-bearing capacity of the hinges.
2. Good concealment
For the sake of aesthetics and safety, anti-theft door hinges usually have good concealment. Some hinges are designed to be hidden and installed inside the door and frame, so that the structure of the hinges cannot be seen from the outside. This can prevent criminals from opening the door by damaging the hinges. Even for external hinges, appropriate decorative treatment will be carried out to match the overall style of the door body and door frame, without affecting the appearance of the anti-theft door.
3. Rust and corrosion prevention
Due to frequent exposure to air, hinges are susceptible to rusting in humid environments. Therefore, most anti-theft door hinges are made of materials with good anti rust performance or have undergone anti rust treatment. Stainless steel hinges themselves have good corrosion resistance, while for cold-rolled steel hinges, rust prevention treatment is carried out through processes such as electroplating and painting. After these treatments, the hinges can be used for a long time in harsh environments (such as high humidity areas) without rusting, ensuring smooth and safe door opening and closing.
4、 Cat's Eye
1. Clear field of view
The optical structure design of the anti-theft door peephole is reasonable and can provide a clear outdoor view. It usually consists of two lenses, with the outer objective being a concave lens and the inner eyepiece being a convex lens. This combination can shrink and focus the scene outside the door, allowing people indoors to clearly see the situation outside. For example, under normal lighting conditions, a cat's eye can see people and objects within 3-5 meters outside the door, and can distinguish the general outline and expression of the characters.
2. High security
In order to prevent criminals from unlocking through peepholes, modern anti-theft doors have various security designs for peepholes. Some cat eyes use anti pry structures and reinforcement devices are installed at the installation site, making it difficult for the cat eyes to be pried off from the outside. Some cat eyes are also equipped with built-in blocking devices, which can cover the cat eyes when there is no one indoors, preventing outsiders from peeping into the indoor situation.
3. Easy installation
The installation of cat eyes is usually more convenient. Its size is generally standardized, and suitable installation holes are reserved during the manufacturing process of anti-theft doors. During installation, simply insert the peephole into the mounting hole and secure it by tightening the nut or using a buckle. Moreover, cat eyes have strong versatility, making it easy to find a suitable model for replacement when needed.
