When choosing indoor door locks, handle locks are essential. They are widely used in indoor doors and are one of the most diverse types of door locks due to their wide range of applications. However, as users, most of us only focus on the brand and appearance of door locks, and our knowledge of the internal structure of handle locks is very limited.
In fact, a proper understanding of the structure and composition of the handle lock is helpful for selecting high-quality locks and for future use and maintenance. Now, let's take a look at the structure diagram of the indoor handle lock with my friends.
Part One: Handle
When choosing a door handle, in addition to conforming to the design style and Chinese good intentions, special attention should also be paid to the electroplating process on the surface of the handle. A good electroplating process requires 8 layers of polishing and 12 layers of electroplating to ensure its wear resistance and corrosion resistance. If the electroplating process is not up to standard, the door lock will quickly become dull and have surface spots. The quality of electroplating technology and materials are the main indicators that determine the price of door locks.
Part 2: Panel
The material and thickness of the panel are very important. Using high-quality materials can prevent panel deformation, and electroplating technology can prevent rust and spots. The door lock thickness of Tiannu Hardware reaches 2mm, and the edge thickness reaches 2.2mm. After 24 hours of smoke testing, it has been sealed with clear varnish for more than 4 hours, and the paint temperature reaches 150 degrees. The surface is smooth and smooth, effectively preventing corrosion, more wear-resistant, and does not stick to dust or grease.
Part Three: Lock Body
The lock body is the core of a lock, which is the key and core parts, generally divided into single tongue lock body and double tongue lock body. The basic composition consists of five parts: shell, main components, lining plate, door buckle, plastic box, and screw accessories, and the materials used for the five parts are also different. The lock body shell is usually made of galvanized iron sheet and does not require electroplating; The main body is generally composed of zinc alloy and high-quality iron; The lining plate is made of stainless steel and copper, and many brands have company logos here; The door latch is made of stainless steel, stainless iron, and copper.
Part Four: Lock cylinder
The lock core is the main component that controls the opening of the lock, and is the heart of the lock. It refers to the core part that can rotate and drive the lock bolt to move when matched with the key. It is generally divided into five types: large hoist, small hoist, fake hoist, angle key, and large lock series.
Part 5: Accessories
Accessories are an organic component of a lock, and everyone understands a truth: a thousand mile dike can collapse in an ant nest. A small accessory can ruin a precision machine, and the small accessory inside a lock is equally important.
