Anti-drilling and anti-vandalism design: an important feature to ensure the security of Brass Lock Cylinder

1. Basic principles of anti-drilling design
Anti-drilling design is a security design for the lock cylinder to prevent drilling tools (such as electric drills and hand drills) from attacking it. Drilling attacks are a common method used by thieves to destroy the internal structure of the lock cylinder in a short time, thereby opening the lock. In order to deal with this threat, brass lock cylinders usually adopt the following anti-drilling measures:

(1) Hardened steel balls and metal sheets
The lock cylinder may be designed with hardened steel balls or metal sheets, which can resist the intrusion of drill bits. Hardened steel balls are precisely set inside the lock cylinder to block drill bits, and drill bits cannot easily penetrate these hard objects. Metal sheets are fixed in a specific position to prevent drilling tools from contacting the core part, thereby enhancing the lock cylinder's anti-drilling ability.

(2) Titanium alloy or hardened brass materials
Some high-end Brass Lock Cylinders use titanium alloy or hardened brass materials as the outer shell and core materials of the lock cylinder. These materials are hard and have strong anti-drilling ability. They can effectively improve the durability and drill resistance of the lock core and extend the service life of the lock.

(3) Special structural design
In the design of brass lock cores, manufacturers will cover some key parts that are easily attacked by drilling, such as the internal springs and pins of the lock core, with special protective structures, making it difficult for drilling tools to directly attack these important components.

2. Anti-destruction design: Improve the lock core's ability to resist external force damage
Anti-destruction design is a method designed to enhance security against external force attacks. Attackers often use tools such as crowbars and hammers to carry out violent destruction. Therefore, anti-destruction design should not only improve the lock core's drill resistance, but also increase its impact resistance and pry resistance.

(1) Anti-pry shell
High-quality brass lock cores adopt an anti-pry design in the shell design, that is, by thickening the shell and using high-strength metal materials, the lock core is not easy to be pried open when under force. The shell of the lock core can be made of steel, aluminum alloy or other high-strength metal materials. This design effectively prevents the use of tools such as crowbars to damage the lock core shell.

(2) Strengthened lock core structure
In order to prevent prying and damage, the internal structure of the lock core is often reinforced. For example, the core of the lock core may adopt an integrated design instead of multiple parts spliced ​​together. Such a structure can reduce the risk of loosening and deformation of the internal parts of the lock core and improve the lock core's ability to resist damage.

(3) Protect the connection between the lock tongue and the lock core
The connection between the lock tongue and the lock core is the part of the lock that is more vulnerable to external force attack. In order to enhance the lock core's ability to resist damage, some high-security brass lock cores use special protective devices at the connection. These protective devices can not only effectively prevent violent damage, but also prevent damage or breakage of the connection between the lock tongue and the lock core.

(4) Visual anti-tampering design
Some high-security lock cores are designed with anti-tampering windows or logos. When the lock core is disturbed or damaged by external forces, users can observe whether the lock core has been damaged through these windows or logos. Although this design itself cannot prevent damage, it can provide users with an immediate warning and reduce property losses.

3. Comprehensive protection combined with other security features
Anti-drill and anti-vandalism designs are two important aspects to improve the security of brass lock cylinders, but they usually work together with other security features to achieve more comprehensive protection. For example, many brass lock cylinders also have anti-pick and anti-bump designs. These designs usually use complex spring and pin systems to prevent locksmiths from using pick tools or impact techniques to open the lock cylinder.

(1) Anti-pick design
Anti-pick design increases the complexity of the lock cylinder by setting multiple springs and pins. Pick attackers usually use small pick tools to insert into the lock cylinder and open the lock by adjusting the pin position. Anti-pick lock cylinders use multiple pins and stagger the pins, making it difficult for pick tools to break the lock cylinder in a short time.

(2) Anti-spring design
Anti-spring design is a protection against the "vibration unlocking" technology. By designing a special internal structure of the lock cylinder, it is not easy to open by mistake when it is subjected to external vibration. Anti-spring design usually includes setting the tension of the spring and complex mechanical coordination inside the lock cylinder to enhance the shock resistance of the lock cylinder.
