Nowadays, the market of hardware locks in China is quietly changing. The development trend of the market is that the door lock has become the leader, the car lock has become a new industry, furniture and office locks have become the new darlings, and high-end locks have become the development direction of locks... Locks, a seemingly insignificant commodity, play an extremely important role in life. It can be said that in our daily life, it is indispensable everywhere. People attach importance to and dependence on “lock†and it has become an indispensable part. It plays an important role in our daily life.
In the face of the shutter lock, it seems that many people are still very strange. In fact, it is a kind of multi-joint movable door series connected together, in the fixed slide, the upper and lower doors are rotated around the reel above the door. Because of their own characteristics and advantages, these products are suitable for public places or houses such as commercial facades, garages, shopping malls, hospitals, factories and mines. In particular, the door opening is large, and it is convenient and quick to open the place where the ground door body is inconvenient. Such as for garage doors, shopping malls, fire shutters, hangar doors. Most of the existing shutter locks on the market in China use the lock head to drive the inserts of the two toilets directly into the holes in the guide grooves on both sides of the rolling shutter. The biggest disadvantage of the designed shutter lock is the poor structural safety performance. The cockroach is not strong, and the thief can use the ordinary pliers to open the guide grooves on both sides, thereby completely destroying the locking device of the roller shutter. In this way, the shutter lock does not protect the property and personal safety of the residents.
In view of the various shortcomings of the products in the existing shutter lock market, Cheng Wenhu of Changzi County, Shanxi Province is determined to change the design and technical problems of these products. He has always been born with a character who is good at understanding the character and tenacity of everything. He has a strong interest in repair, manufacturing and invention since he was a child, and he grew up and built and repaired the door industry. The accumulated experience. With these advantages, Cheng Wenhu and his own expertise in the manufacture and repair of roller shutters, the development and invention of the roller shutter lock, for Chengwen Tiger, has become a natural thing.
After repeated research and experimentation, especially when he encountered many problems on the technical level, he still persisted. Finally, after painstaking research and successful overcoming difficulties, the success of the invention of the new rolling shutter lock was finally achieved. He invented a new and practical shutter gate, the full name of the invention is: internal and external key lock shutter lock (patent number. 8).
The utility model provides a safety gate lock with high safety performance against the disadvantages of the existing shutter lock technology. The technical method adopted by the utility model is: a rolling shutter lock, comprising a lock head, a plunger and a bottom beam, characterized in that it further comprises a bottom beam ring welded on the bottom beam, a floor fixed on the ground and welding The ground ring on the floor. The middle section of the plunger is welded with a plunger hook. When the roller shutter is locked, the bottom beam ring covers the ground ring, and the plunger is located in the ground ring on the bottom beam ring. The utility model adopts the structure of the ground ring, the bottom beam ring and the plunger hook. When the rolling gate is closed, the rolling shutter lock is integrated with the earth, the anti-smashing performance is high, and the safety is further improved. The working principle of the invention is that when the roller shutter is dropped, the bottom beam rings on both sides are automatically inserted into the ground ring, and then the key is turned, and the hook head is inserted into the ground ring mouth located above the bottom beam ring, and the two ends of the plunger are inserted into the rolling gate In the holes of the guide grooves on both sides, the shutter is locked at four points at the same time. Then turn the key, the plunger and the hook head respectively come out from the hole in the guide groove and the ground ring, and the locking device is released. The rolling shutter naturally rises. When conditions permit, two hooks are welded on the plunger, and two bottom beam rings are installed. Two ground rings can be locked at 6 o'clock at the same time, even in the case. Add the corresponding accessories, which can be locked at 8 o'clock at the same time. This design enhances the safety of the product and ensures the safety of the user's property and personal safety.
After careful research and repeated trials by Cheng Wenhu, the product finally came to market. Cheng Wenhu himself said that the rolling gate lock is only a small invention project. It is only based on the popular rolling shutter locks on the market, and has made some adjustments and improvements to the existing structural design deficiencies. The technology is very simple. The original shutter lock can lock two points. After the bold imagination and improvement of Cheng Wenhu, he invented the shutter lock to lock 6-8 points. At the same time, this invention has a greater advantage than similar products: the locks that have been improved by this invention can be applied to various types of rolling gates, and the application objects are no longer single, and the market prospect is broad. The roller shutter lock he developed is a practical and technical product. Its most important contribution is to provide a safer and more reliable shutter lock device for the general public in daily life.
Faced with this invention, Cheng Wenhu said that the invention is easy to use and simple in structure, and investors only need 10,000 yuan to invest in a rolling shutter factory. The current profit is 25-30 yuan per square meter. The initial workers only need three or four. The single cost of the rolling shutter device is less than 10 yuan. It is calculated according to the average of 10 square meters of a rolling gate. Its added value is 50,000-300,000 yuan. Between, coupled with its upcoming market share, the outlook is very impressive. Therefore, the internal and external key lock shutter locks as a technological innovation of the shutter safety, coupled with its upcoming market share, have huge market potential. If a provincial-level rolling shutter fittings manufacturing plant is constructed in accordance with the business model of the internal supply of the rolling shutter fittings, the annual sales volume and profit cannot be estimated. If the development prospects are objective, coupled with the future implementation of the business model provided by the rolling shutter fittings in the licensed area, the construction of a provincial-level rolling shutter fittings manufacturing plant, its annual sales and profits can not be estimated.
In the face of various technical deficiencies in China's rolling shutter lock market, if the products invented by Cheng Wenhu can be listed early, it will bring huge economic benefits to producers and investors. We sincerely invite people at home and abroad to develop this product together, promote the transformation of results, create more social and economic value, and provide corresponding hardware guarantee for the personal safety and property safety of consumers.
