Material and surface treatment
From the interview, the author also found that users generally worry about the locks are not durable or the surface will be oxidized and rusted when the locks are purchased. Therefore, the selection and surface treatment of the lock materials will be very important.
1, material
It is understood that manufacturers currently use stainless steel as the material of the lock. However, there are many kinds of stainless steel, which can be mainly divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless iron. It will rust when the time is long and the environment is not good. Only austenitic stainless steel will not rust, and the more it is used, the brighter the color will not change. The identification method is very simple, and it can be identified by a magnet.
In addition to stainless steel, copper is one of the more widely used lock materials. According to Deng Wei, Sales Director of Assa Abloy Project, due to the good mechanical properties of copper, the corrosion resistance and processing performance are good, and the color is gorgeous, especially the copper forged handles and other locks, the surface is flat, the density is good, and there is no porosity. The trachoma is both strong and rust-proof. It can be used for plating various surface treatments such as 24K gold or gold. It looks magnificent, noble and generous, adding a lot of color to people's home. The Adil technician also said that part of the company's lock surface is also made of high-tech chrome-plated or pure copper surface nano-treated, the texture is good and durable, it will not fade after ten years of use, and can meet the requirements of modern and classical style decoration materials. .
In addition to these materials, there are some zinc alloy materials, aluminum or aluminum alloy materials. “But the strength and rust resistance of these materials are much worse, but the advantage is that it is easy to make parts with complex patterns, especially for pressure casting. The locks of more complicated patterns seen in the market are probably made of zinc alloy, users Carefully identify when purchasing,†suggested Deng Wei, Sales Director of Assa Abloy Project.
2, surface treatment
To prevent the lock from rusting, the manufacturer will surface the lock. Surface treatment refers to the technique of covering or forming a protective film on the surface of a part by metal electrodeposition (commonly known as electroplating), painting (called spraying), chemical oxidation (coloring) or other processing methods. The film mainly acts as a preservative, and at the same time increases the aesthetics and durability of the product, which is an important factor for directly measuring the quality of the product. Common methods for determining the quality of surface treatment include: cover thickness measurement, adhesion test, salt spray and moisture test, visual inspection, and the like. The coating can be applied by coating adhesion, hardness, moisture test and visual inspection.
According to the Adil technical staff, the company's hotel door lock surface and lock cylinders use the most advanced PVD surface treatment technology to protect the lock from the external environment and natural climate, corrosion resistance and long life.
Lock machining process
The machining process of the lock is mainly aimed at the improvement of the lock core technology. “Many manufacturers have done a lot of improvement on the lock core part and produced the products according to the needs of the users, which not only ensures the reliability of the products but also has a relatively rich function.†Zhang Tanghui, chief lock expert of Hongrong Group, said .
It is understood that the lock cylinder includes a combination of a diagonal tongue, an anti-plug oblique tongue and an anti-locking large tongue. "The anti-plugging tongue adopts the rail-type design to fully solve the problem of non-insertion due to the gap after the door aging. The anti-locking tongue has two special tungsten steel columns, and its anti-destructive strength is doubled." The technician said.
“In addition, according to the three-dimensional motion principle of the three-dimensional space, we adopt the rail-type motion connection and the bolt-proof lever anti-wear and assistive design. The whole lock core structure is simple (all parts are only 50% of the plane structure lock cylinder), and the failure rate is low. To achieve a perfect unity of reliability, dexterity and safety," added the Adil technician.
Electronic control
It is understood that in the electronic control, many intelligent door lock control circuit boards use SMT technology, through high temperature aging, online testing, vibration aging, dipping paint moisture-proof production process, thus eliminating indoor and outdoor The temperature difference causes the moisture inside the door lock to condense and damage the components of the circuit board , which improves the reliability and stability of the circuit.
In addition, some smart door locks also use intelligent coding technology and anti-glare interference technology, which makes the power consumption of the door lock very low, which reduces the frequency of replacing the door lock battery . According to Zhang Tanghui, chief lock expert of Lerong Group in Hong Kong, the electric control locks currently seen on the market, whether domestic or imported, generally have a working power consumption of several watts (W) to about ten watts, that is, the working voltage is mostly 12-24V, working current is 0.2-2A, due to low efficiency and high power consumption, it is almost impossible to apply in some places where the power consumption is very strict or the power is often cut off.
Therefore, the low power consumption of smart locks is also the design focus of electronic control. Assa Abloy electrically controlled lock operating voltage is generally 3-6V, the average current is only several tens of milliamperes (≤100ma), coin-shaped lithium battery can be unlocked about 1 million times. All series of different types of electronically controlled locks can be unlocked by the same drive mode (module), which greatly reduces the power consumption of the lock.
Smart design for the user
In order to make the user more convenient to use, manufacturers have put a lot of effort into the humanized design of the lock. Ideal's fingerprint lock uses a free-standing "space clutch" technology, designed as a movable handle. When the clutch is closed, the handle is stressed. When the clutch is disengaged, the handle is idling, effectively preventing external violence from damaging the internal structure. Open the door lock and really achieve the effect of the handle "free". In addition, the lock also has a normally open and normally closed setting function, which is convenient for people to use when entering and leaving frequently, and it embodies a humanized design concept everywhere.
Only when you think more about the user can you perform well in the design details. According to Zhang Tanghui, chief lock expert of Lerong Group of Hong Kong, the company's fingerprint lock can directly register and cancel 240 fingerprints on the door lock. The owner has the largest usage right and can freely perform fingerprint registration, deletion, record query and other management functions. . In addition, on the top of the lock, an intelligent digital display is specially designed to confirm whether the key input is valid when the user enters the password, and avoids many troubles caused by repeated key presses.
Moreover, many manufacturers' locks also provide various software interfaces such as TXT, DLL, SHELL, EXE, etc. for various property management software and hotel management software, which is convenient for other software integrators to integrate when calling, which is used when customers integrate intelligent systems. And the property management brings greater convenience and humanity.
Enhance the added value of real estate and create a new era of smart home
With the continuous improvement of lock technology and the continuous implementation of the new real estate policy, the technical quality of high-end residential has become more and more a real selling point of residential products. According to industry insiders, there will be more high-tech attempts in the real estate market, because the adoption of high-tech systems can not only provide data-based product performance indicators, but also achieve the essential improvement of residential quality and create more high-quality residential buildings. product.
It is understood that many real estates at home and abroad have introduced smart locks to improve quality. Ordinary real estates are generally equipped with password locks, proximity card locks, etc., while some of the more upscale properties are beginning to install fingerprint locks. In addition to the Beijing Olympic athletes' apartments, such as the Vanke Group's World Leisure Expo theme leisure villa “Venice Water Cityâ€, which is developed in Hangzhou, has installed 1,850 sets of fingerprint locks; Zhejiang Greentown Group developed “Emerald City†using 8,500 sets; Hangzhou “Kissing Home†After the first batch of villas used fingerprint locks to achieve good market results, the common rough houses have also begun to be widely used, and the number of assembly has reached 9,850 sets. Jiaxing “Jindujiayuanâ€, Nanjing “Shanmeng Huamenâ€, Hangzhou “Oriental Golden Blockâ€, “Qianjiang Times Buildingâ€, “Suulstown Townâ€, “Mediterranean Villa†and other high-end real estates have used a large number of smart locks. .
Feedback from some developers shows that because of the practical, convenient, and safe functions of smart locks, the real estate sales scene has strongly attracted the attention and interest of buyers, so that customers are very interested in the process of buying houses. Naturally, there is a great tendency. Especially the elites of the society have a strong resonance and recognition for this exquisite and stylish configuration.
