The birth of Chinese locks has been going on for thousands of years, and wooden locks have been discovered at the Yangshao Cultural Site.

With the improvement of people's living standards, people's awareness of prevention has strengthened. Therefore, the demand for high-grade preventive locks has been increasing. In the consumer market of locks, high-tech products such as biometrics and electronic technology are still in a blank stage, but the demand and desire of consumers in this market has shown an annual growth of 40%. In 2012, China's domestic lock market's share of high-tech products such as biometrics and electronic technology reached 8 billion U.S. dollars and a total of more than 80 million sets, which is definitely an attractive big cake.

The core technology of high-end locks is in the hands of foreign manufacturers. The core electronic components of high-end electronic locks such as IC cards, TM cards, fingerprint locks and other products are imported from abroad, which limits the price and performance expansion of China's high-end locks.

Some high-end hotels, hotels and other locks are mainly imported, and the domestic high-end lock market is still controlled by foreign locks. It is time for the domestic lock industry to turn to technology, high-end, and intelligent locks for profit.

Lock companies urgently need innovative brands to seize the market: China's lock manufacturers have increased their efforts in the development of high-end lock products, such as Yantai Sanhuan Lock Industry Group Corporation, Shandong Jinfeng Group Company, Zhongshan Huafeng Lock Co., Ltd. With reference to European and American standards for production, independent innovation technologies continue to emerge, and it has obvious competitive advantages in domestic and foreign markets.

At the same time, well-known foreign lock-making companies such as the United States, Italy, Germany, Japan, Canada, and South Korea have accelerated their pace in entering the Chinese market. Local brands and foreign brands have faced head-on confrontation in the high-end lock market. Anyone can achieve the upgrade, and thus get the biggest cake.

A lock seems simple, but it can be completed through 110 procedures. The lock industry is both a traditional industry and a close connection with high technology. Today, with the rapid development of lock technology, we do not master advanced equipment and design levels, With high-quality professionals, it is difficult for companies to lead the industry.

On the whole, China's lock industry is lagging behind advanced foreign technology, and lock manufacturers are mainly small and medium-sized enterprises, and low-level redundant construction is serious.

Some small enterprises have backward equipment and are still in the purely mechanical manufacturing stage. They are still far from the new type of locks integrating light, mechanical and electrical integration, which has brought hidden dangers to the quality of the entire lock industry. The high mutual opening rate of the locks and the poor prevention have also caused dissatisfaction among many consumers.

In order to maintain the appearance of the lock and prolong the service life of the lock, during its daily use, attention should be paid to its maintenance and upkeep.

1. Always keep the transmission of the lock body with lubricant to keep its transmission smooth and prolong its service life. It is recommended to check once every six months or one year and check whether the fastening screws are loose to ensure tightening.

2. During the use of the lock, periodically (half a year or one year) or when the key is not inserted smoothly, you can put small graphite powder or pencil powder into the lock cylinder groove to ensure the key is inserted smoothly. But do not add any other oil for lubrication, to avoid the oil from sticking to the ball spring, resulting in the lock head not turning and cannot be opened.

3. Frequently check the clearance between the lock body and the lock plate, and whether the height and height of the lock tongue and the hole in the lock plate are suitable. The optimal clearance between the door and the frame is 1.5mm-2.5mm. If changes are found, adjust the position of the hinges or the locking plate on the door. At the same time, pay attention to the cold shrinkage and thermal expansion caused by the weather (wet in spring and dry in winter) to ensure that the clearance between the door and the door frame, the lock body and the lock plate is reasonable to ensure the smooth use of the lock. , Specifically, you can directly ask the manufacturer's people when buying.

First, appearance maintenance:

1. During the decoration of the house, please use plastic bags (do not contact the adhesive surface of the self-adhesive tape with the surface of the lock) to seal the exposed parts such as the handles and panels of the lock, so as not to bring the surface treatment layer of the lock parts with Erosion of acidic or alkaline materials and gases produces spots, blistering and even delamination, which seriously affects the appearance quality of locks. Some zinc alloy and copper locks will have "spots" when they are installed on the door for a long time. This phenomenon does not belong to rust, but belongs to oxidation. If this happens, just spray it with surface wax. You can remove the spots.

2. In normal use, if there is dirt, it can be removed with a dry cloth. Never use chemicals such as detergent. Otherwise, it will damage the protective film of the exposed parts and cause discoloration. Do not wipe the lock body and handle with a wet cloth, because some metal locks will rust; alloy locks will wear away the plating and lose the aesthetic effect.

Performance maintenance

1. During use, periodically (half a year or once a year) or when the key is not inserted smoothly, add some graphite powder (pencil powder) in the keyhole for lubrication. Do not add any liquid oils as Lubricant to prevent the oil from sticking to the spring, and the lock cannot be turned and cannot be opened. If it is more laborious to close the door leaf, you can apply a little pencil powder on the oblique tongue.

2. When closing the door, it is best to hold the handle, screw the lock tongue into the lock body, and release the hand after closing the door. Do not hit the door with force, otherwise the service life of the lock will be reduced.

3. When the main bolt or safety bolt is protruding out of the door, do not hit it violently to avoid damage to the bolt and door frame.

4. Because the sealing strip installed between the door body and the door frame has an elastic force, when the handle or key is used to unlock the lock tightly, you can push the door or pull the door to overcome the elastic force while opening the door. Do not turn the handle or key forcefully. Open the door to avoid breaking the handle or key.
