There are more and more types of locks on the market. What is the most common use today is the handle lock. What is the structure of the lock? The handle lock structure is generally divided into five parts: handle, panel, lock body, lock cylinder and accessories. The following sections describe each part in detail.
Five major parts
Part 1: Handle
Handle, also known as door handle, is made of zinc alloy, copper, aluminum, stainless steel, plastic, logs, ceramics, etc. The door handles commonly used in the market are mainly zinc alloy and stainless steel.
Select the door handle, and pay special attention to the plating process of the handle surface. A good electroplating process requires an 8-layer polishing process and a 12-layer electroplating process to ensure wear resistance and corrosion resistance. If the electroplating process is not closed, the door lock will soon become very dim and the surface will be spotted. The quality of the plating process, the quality of the material is the main indicator of the price of the door lock.
Part II: Panel
The panel is divided into a door lock or a door lock from the length and width of the panel, so the panel is also an important factor when purchasing.
The size of the door panel is not the same. According to the opening size of the wooden door, the lock is selected. Before buying, we must also know the thickness of the door in the house. The thickness of the door is 38-45mm. The special thickening door requires special door lock treatment.
The material and thickness of the panel are important. The high-quality material prevents the panel from deforming. The plating process prevents rust and spots.
Part III: Lock body
The lock body is the core of a lock, which is a key part and a core part, and is generally divided into a single tongue lock body and a double tongue lock body. The basic structure is: shell, main part, lining, door clasp, plastic box and screw fittings. The materials used in the five parts are also different. The lock body has the difference of a single tongue lock body and a double tongue lock body. The single tongue generally has only one oblique tongue, and has two specifications of 50 and 1500px. This size refers to the middle hole distance of the liner part to the square hole of the lock body.
The double tongue lock body includes a slanting tongue and a square tongue, and the good locking tongue is made of 304 stainless steel to prevent the lock body from being damaged and the anti-theft performance is better.
The larger the lock body, the more expensive the general price is. The multi-function lock body is generally locked with a large door. Its anti-theft performance is very good and the price is very expensive. The lock body is the functional part of the lock and the most critical part. .
Part IV: Lock cylinder
The lock cylinder is the main part that controls the opening of the lock. It is the heart of the lock. It refers to the core part that can rotate with the key and drive the movement of the lock bolt.
The material and process of the lock cylinder have a great influence on the lock. The lock core of the mortise lock generally adopts a marble structure and a blade structure, and a blade structure with a hook, that is, a lock lock. The more complex the general structure, the lower the mutual opening rate.
The lock cylinder is preferably made of copper. If it is made of zinc alloy or even aluminum alloy or plastic, the cost is much lower, but it is easily damaged. There is also a stainless steel material that is of even better quality.
Part 5: Accessories
The accessories are the organic composition of a lock. Everyone knows the truth. The embankment of a thousand miles collapses in the ant nest. A small accessory will ruin a precision machine, and the same small gadget inside the lock is also very important.
The big brands are made of stainless steel screws, which are high in hardness, durable and rust-free. If iron screws are used, it is easy to rust, easy to slip, etc. It is not uncommon for a good lock to give a bad screw to be destroyed.
The key is also a kind of accessory. Sometimes you will find that the key is rusted, or the key is bent, or when the key is unlocked, the key is broken in the keyhole. These conditions are related to the material of the key. The inferior key is used. It is made of iron, without QC, and the heavy metal exceeds the standard. Excessive contact is harmful to the human body.
The real good key is made of white copper material, ensuring that the key is not rusted and deformed by time, and the unique design can effectively distinguish other keys, and the design is more user-friendly and prevents hand slipping.
