Introduce a few good locks
There are two points to consider when locking a lock: From the wind Steel Cord Conveyor Belt,ST4000 Steel Cord Conveyor Belt,ST4000 Steel Cord Conveyor Belt Steel Cord Conveyor Belt Co., Ltd. , http://www.nsconveyorbelt.com
1. Technical safety
2, anti-riot security
Technical security means that this lock is not easy to open, the worst is the old one-word lock, I think no one will use this, the thing will open in two seconds.
In the first two years of the country, the atomic lock is very loud. The old one is useless. In the game, it is also a two-second item. There are also cross locks and round locks. Please ignore them.
Nowadays, it is probably the moon lock, and the crescent has the difference between true and false. Some of the crescent locks are still in the word, and the typical one is the one with the teeth on both sides of the key. . . Well, be careful with JS.
The real crescent lock has no teeth on both sides, and it is not very good, but it seems to be possible if there is violence.
Taobao sees the good locks are the most advanced DISK lock core in the world. It is said that the lock is used in the bank . Therefore, since it costs a lot of money to buy a lock, it is very necessary to find a DISK lock cylinder.
Anti-riot security is better understood, that is, whether it can be cut by violence.
The fat man said: no locks and cuts constantly.
His statement is right, but a lot of good steel and steel difference, the difference, the difference of steel can be directly sawn, good imported steel blade is very difficult to saw, the length of time, that is, whether the thief dare hands of the key.
The quality of steel, I did not remember, generally high-strength manganese steel, did not clear the exact name.
There are several kinds of locks that are seen on Taobao:
Steel armor, owl, Liba, these are Taiwanese, in fact, the same manufacturer, there is no difference in quality , the price is high and low.
There are friends in the forum who bought owls. The price of Taobao is between 230 and 250. According to the owner, all the goods are smuggled. If the key is lost, there is no match. The original price in Taiwan is about RMB500. The online price in Taiwan is about RMB340.
The price of the steel armor is generally around 280, which is also smuggled. The domestic agent's authenticity needs 400.
Liba found a short version of the owl, quoted 200, only two keys, less, the same, smuggled goods.
Then, I found the lock that the fat man bought. This guy is still not willing to report the NND.
What is found on Taobao is: Universal all-steel anti-riot U-type anti-theft lock. Taobao offer: 185
I am close to the owner of the store, saying that I bought the friend of the 160. . . The result, success, 160 start, freight 15 yuan, take Shentong Express (send EMS is pig ~~~)
After comparing it, the steel for steel armor and owl may be better, at least it looks much more beautiful, the steel armor has the manufacturer's measured data, the owl has a TV live performance (trashing the truck ```), Liba is It's a short version and the materials are the same.
General-purpose steel, according to the literal introduction is a kind, the specific does not understand. GM is domestically produced for export. The standard should be very high, but I always feel that this GM is set up in China. The quality of steel is the same as that of foreign countries~~~
But what I think is GM: it has to cut both sides to get rid of it! Compared: Steel Armor / Owl / Liba only have to deal with one side and it is OK.
Of course, the price is also the key, and the difference is quite a lot.
Send a few pictures, respectively: steel, owl, Liba, general, pay attention to the key in the picture, DISK lock core is the key of this, these are all DISK lock core
