One, the difference between door handles and knobs
- Handles are typically used on drawers or doors with exposed locks, providing a secure grip for opening.- Handles are generally categorized into single-point handles and actuator handles, which are rotatable and work in conjunction with actuators to lock and unlock doors and windows.
Two. Internal structure of the "Hand Lock"
The structure of a mortise lock is generally divided into five parts: the handle, the panel, the lock body, the lock core, and accessories.
Part 1: Holding
Door handles, also known as levers, are available in materials such as zinc alloy, copper, aluminum, stainless steel, plastic, wood, and ceramic. Currently, zinc alloy is the most commonly used material for door handles due to its excellent plasticity, allowing for designs in various shapes and colors, and the ability to create unique decorative elements. When selecting a door handle, it is important not only to ensure that the style matches the design and Chinese aesthetic preferences, but also to pay close attention to the electroplating process on the handle's surface. High-quality electroplating requires a process of 8 layers of polishing and 12 layers of electroplating to ensure durability and corrosion resistance. If the electroplating process is poor, the door handle will quickly become dull and develop spots. The quality of the electroplating process and the material itself are the primary factors determining the price of the door handle.
Part 2: Hand-Operated Door Lock Panel
The size and dimensions of the door panel determine whether it is suitable for a front door or a room door. Therefore, the door panel is an important factor to consider when selecting a lock. When purchasing, it is essential to determine the thickness of the door, which is typically 38-45mm for standard doors. Special locks are required for thicker doors. The material and thickness of the door panel are also important. Using high-quality materials can prevent the panel from warping, and electroplating can prevent rust and discoloration.
Part 3: Hand-operated door lock body
The lock core is the essential part of a lock, comprising the critical components. It is generally divided into single-tongue locks and double-tongue locks. The basic components include: outer shell, main body, backing plate, strike plate, and screw accessories. The materials used in these components also vary. The outer shell of the lock core is typically made of galvanized iron, without the need for electroplating; the main body is usually composed of zinc alloy and high-quality iron; the backing plate is made of stainless steel and copper, often with brand logos; and the strike plate is made of stainless steel, stainless iron, and copper. Larger lock cores generally have a higher price, and multi-functional lock cores are often used in main doors due to their excellent anti-theft performance and high price. The lock core is a crucial part of a lock and is often the cause of lock failure.
Part 4: Hand-operated door lock core
The lock core is the primary component that controls the lock's opening mechanism. It is the central part of the lock, responsible for rotating and moving the locking bolt when used with a key. Lock cores are generally categorized into five types: large gourd, small gourd, imitation gourd, angle key, and large lock series. The material and manufacturing process of the lock core significantly impact the lock's performance. Lock cores typically utilize a ball-and-spring mechanism, with more balls increasing the security level. The first and last balls function as positioning elements, while the intermediate balls serve as encoders. More intermediate balls result in a lower key duplication rate. It is preferable to manufacture lock cores from copper. However, many commercially available locks use zinc alloy, aluminum alloy, or plastic, which are more affordable but also more prone to damage.
Part 5: Hand-operated Door Lock Accessories
The accessories are an integral part of the lock, and everyone understands that even a small defect can cause a major problem. A small, faulty accessory can ruin a precision machine, and a faulty screw in a lock can have the same effect. Major brands typically use stainless steel screws, which are hard, durable, and resistant to rust. Some smaller brands use iron screws, which are prone to rust and slipping. A good lock can be ruined by a bad screw, and this is a common occurrence.Keys are also accessories, and their quality can affect the lock's performance. If a key is rusted, bent, or broken, it can damage the lock. Poor-quality keys are typically made of iron, which is prone to rust and corrosion. They may also contain heavy metals, which can be harmful to the user. High-quality keys are typically made of pure copper, which is resistant to rust and corrosion. They also have unique designs that make them easy to identify, and they are often ergonomically designed to prevent slipping.
