HC Security Network News About Smart Lock, everyone says is a good thing. Not only is it safer than mechanical locks, it is also more convenient than mechanical locks; and I heard that in the United States, Japan, South Korea, and many developed countries in Europe, basically every household has used smart locks.
And in China? You ran to the street and grabbed the individual to ask: "Do you use smart locks in your home?" "You know the smart lock brands." I believe 80% of people say: "NO, don't know !"
Yes, this is the status quo of China's smart lock industry. Then, every household in the family is using smart locks. Should we Chinese people change smart locks?
The answer of course is yes, the Chinese satellites can fly to the sky, the vast stars have the image of our heavenly palace, and our supercomputer computing speed has ran out of the world first... So, in terms of smart locks, Chinese people Never lose to the nuts.
So, how popular is the foreign smart lock penetration rate? According to authoritative data, in the United States, Britain, France and other European and American countries, more than 52% of people have used smart locks, and they have been used more than a decade ago. Smart lock.
Let’s take a look at our neighbor, South Korea. Don’t look at his recent troubles. The former president has just been arrested. The new president is still struggling for “Sadeâ€, but the popularity of smart locks is close to 80%. .
Looking at us across the sea, and Japan, which competes with us for the Diaoyu Islands, the popularity of smart locks is also prohibitively high. How high are you guessing? The data shows that the penetration rate of smart locks in island countries in Japan has exceeded 70%.
And what about China? A big country with a history of more than 5,000 years, the second largest economy with a population of 1.3 billion, can use smart locks but few pitiful, it is said that it is less than 3%. This obviously does not match the international image of the second largest economy!
Therefore, compared with developed countries, we are seriously lagging behind in the popularization of smart locks. However, from this point of view, it is very necessary for us to “overtake the United States to catch up with the United States†and even surpass our neighboring countries, Japan and South Korea. Match the image of our big country.
Really, it’s better than not knowing, it’s scary! Even if you don’t compete with the glutinous nuts for any face project, from the actual needs and applications, do we Chinese need to install smart locks?
Before answering this question, let us first look at a set of data: There are 1.6 million cases of burglary in China every year, and more than 70% of them are caused by the insecurity of mechanical locks. Of these cases, 65% were locked into the room by technology.
The burglary brought us a loss of property, but the loss of the key has brought life to many people. According to the data, there are more than 17,000 incidents in China that have been forcibly taken over by the forgotten keys and lost keys.
Therefore, whether it is burglary or climbing into the building, it is a mechanical lock and a mechanical key. Therefore, it is very necessary for us to install a smarter lock that is safer and more convenient.
So is the smart lock safe? The answer is yes. As long as it is a qualified smart lock, it must be safe, because its key is fingerprint, password, mobile phone, etc. It is basically impossible to be copied and the technology is turned on. Destruction, anti-techniques open alarms and remote monitoring, thieves basically do not dare to approach.
So is the smart lock convenient? The answer is also affirmative. The smart lock now has not only the mechanical key, but also the opening method of password, fingerprint, magnetic card, mobile phone, etc. It is convenient and convenient, and it also eliminates the trouble of carrying the key. When the parents came, the babysitter came, the friend came, and you just stopped at home, you can unlock the phone remotely, so it is more convenient to open.
Therefore, in summary, every household in a foreign country uses smart locks. How can Chinese people fall behind? Besides, from the actual anti-theft and personal safety requirements, the Chinese say that they should also install smart locks.

Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. [1] According to material, it can be divided into metal Manhole Cover, high-strength fiber cement concrete manhole cover, resin manhole cover and so on. Generally round. Can be used in green belts, sidewalks, motorway, docks, alleys, etc.
Technical Parameters
Technical parameters Test load: heavy 400KN, general 250KN, light 125KN [1]
Bending strength: average 22MPa impact strength: average 10J / m2
Water absorption rate: 1%
Acid resistance: sample at 20%
Soak in sulfuric acid solution for 48h
No corrosion on the surface, 1% quality loss
Performance characteristics
1. High strength: Magnesite inspection has high compressive, bending and impact strength, and toughness. After long-term use, the product will not be crushed and damaged, which can completely prevent the "urban black hole" accident.
2. Beautiful appearance: The surface pattern design of magnesite inspection manhole cover is exquisite, the color is adjustable, and it can beautify the urban environment.
3. Easy to use and light weight: The product weighs only about one third of cast iron, which is convenient for transportation, installation and repair, which greatly reduces labor intensity.
4. Anti-theft: Magnesite inspection manhole cover has no recovery value and is natural anti-theft; according to customer requirements, a lock structure is provided to prevent theft of property in the well.
5. Strong weather resistance: Magnesite inspection manhole cover can be used normally in the environment of -50 ℃ ~ + 300 ℃ through scientific formula, advanced technology and perfect technical equipment.
6, acid and alkali resistance, corrosion resistance, wear resistance, rolling resistance of vehicles, long service life.
Distinguish by material
Can be divided into 4 categories
A. Metal manhole cover: cast iron, ductile iron, bronze manhole cover, etc .;
B. High-strength steel fiber cement concrete manhole cover (cement-based composite material);
C. Recycled resin manhole cover (recycled resin-based composite material);
D. Polymer-based composite inspection manhole covers, etc.
Differentiate by shape
Generally divided into circular and square.
In terms of road management in urban areas, a circular shape is generally adopted because the circular manhole cover is not easy to tilt, which can better protect the safety of pedestrians and vehicles.
Squares are generally used in rural areas and cable wells to better prevent the ingress of liquids such as rainwater.
