China's lock industry at a glance

The Xiaolan Lock Association has jointly registered a trademark called “Zhongshan Lock” in the State Trademark Office. It is expected that the locks with the “Zhongshan Lock” collective mark will be available this year. Zeng Zhitian, executive vice president of Xiaolan Lock Industry Association, said to the media that he hopes to implement the strategic development model of “enterprise + alliance standard + detection of real insurance room + collective trademark + brand promotion”, and strive to build a regional brand of “Zhongshan Lock”. At present, some business leaders of the Lock Industry Association have raised funds to establish “Zhongshan Xiaolan Locks Co., Ltd.”, which is responsible for the operation, management and brand promotion of collective trademarks.

“Zhejiang and Shandong lock bases are mainly based on batch locks, and the products are relatively low-grade; 'Small manufacturing' is a high-end product in the market.” Liang Fujian, who has been in the lock industry for more than ten years, believes that in finance Under the crisis, only by relying on quality to win, enterprises relying on brand can survive in the big waves. Therefore, Xiaolan’s hardware companies should cherish the reputation already possessed by “Zhongshan Locks” and rely on regional brands to drive the market. Marketing .

In the financial crisis, Xiaolan Lock is seeking a new development path, constantly upgrading the industry, realizing the importance of the brand and driving the high-end route. Xiaolan trivial market is also gradually evolving standardization.

It is precisely because the locksmiths are immense, if there is no certain constraint, it will inevitably lead to unclear management norms and disorderly market management. A few non-compliance locksmiths may bring great risks to the lives of ordinary people. Li Chibing, executive adviser of the Guangdong Lock Industry Association, said that in 2004, the “lock repairman” was included in the national professional ceremony. In January 2005, the national professional standard was promulgated. In 2008, the high, middle and junior grade locksmiths were qualified. Assessment and identification pilot work. The first batch of 69 locksmiths participated in the test. In July this year, more than 20 people participated in the professional qualification.

The state established locksmiths as a new profession, promoted the development of an emerging industry, and created good jobs for young people who are interested in doing so and eager to make a difference.

In foreign countries, locksmiths have a certain social status and have already become a basic mature profession. The government has strict management of repair and unlocking industries, and has clear provisions on the professional and vocational qualifications of employees. There are also strict regulations on professional licenses and annual renewal licenses.

With the decline of the export tax rebate rate, raw material prices and increased instability in the financial crisis of the cost, some domestic enterprises have locks production declined, benefits decline of the situation, individual enterprises and even folded. Generally speaking, the domestic locks market mainly produces low-end lock products. Domestic brands are too chaotic. Although China is a big hardware producer, the brand effect is not strong. Many Chinese lock companies hang on foreign brands to manufacture and sell in China. Locks, brand add-on effects are basically occupied by foreign brands. China's lock industry is a labor-intensive industry. The entry barrier is low and the degree of specialization is not high, resulting in uneven product quality and inferior products flooding the market. The consumption concept and level of the people are limited by this industry situation. The lock industry is basically not updated in essence, and there is no greater satisfaction with people's living needs and related industries - the development of the finished product door industry. For this, Dalian Banglu Lock Li Jianhua, general manager of the company, said: "The reason is that most lock companies lack independent innovation."

In fact, the lock industry has always been a wide range of products. But for many years, the locks developers only made a fuss about the shape and structure of the lock core attachments. The operation methods are similar, and they never break the traditional door locks from the design concept. In response to this situation, Dalian Banglu Lock Industry Co., Ltd. broke the traditional door lock design concept, abandoned the exposed lock tongue, and independently developed a double magnetic recombination mechanism to realize the automatic elastic lock tongue mechanical door lock after closing the door. It solves the historical problem that the traditional lock tongue can be closed normally by hitting the door frame in the past hundred years.

Threaded flange is a flange that connects threads to pipes. When it is designed, it can be treated by a loose flange. The advantage is that there is no need for welding, and the additional torque on the cylinder or pipe when the flange is deformed is very small. The disadvantage is that the thickness of the flange is large and the cost is high. It is suitable for the connection of high pressure pipe.

The threaded flange is made from the inner hole of the flange into pipe thread and connected with the pipe with thread, which is a non welded flange. Compared with the flat welding flange or butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines which are not allowed to be welded on the spot. Alloy steel flanges are of sufficient strength, but they are not easy to weld or have poor weldability. Threaded flanges can also be selected. However, if the temperature changes rapidly or the temperature is higher than 260 C below -45 C, it is recommended not to use threaded flange to avoid leakage.
