2. When turning the mechanical combination lock, turn it slowly and quietly, not violently. At the same time, remember the direction and times. If you accidentally cross the mark line, you can't turn back and have to start again.
3. If the key of the blade lock cannot be inserted, please use a clock screwdriver to turn the blades in the lock hole one by one counterclockwise until the blades are completely aligned.
It is best to set the password when the safe door is open. After setting the password, enter the new password several times, and then lock the cupboard door after it is confirmed.
5. If the key of the marble lock can't be inserted, please poke each marble into the lock hole with a thin steel wire to ensure that the marble is flexible, and then try to open it. ?
6. Never lock the instruction manual and emergency key into the safe.
7. The emergency key is not pressed tightly, so it is impossible to turn the key to open the emergency lock.
8. When the alarm is in use, don't adjust the internal switch and electronic components at will. If the sound becomes lower, it means that the battery is used up, and it should be replaced in an emergency. If there is a false alarm, the sensitivity can be reduced appropriately.
9. If the door bolt of the safe blocks the door, you can push the door tightly and turn the key back and forth to unlock it. ?
10. In order to ensure the safe is fixed reliably, the tapered pin core in the expansion nut must be hammered until the nut is expanded and opened and tightened. The nut is strong enough in the hole in the wall. ?
1 1. The door handle drive mechanism of the safe blocks the key locking mechanism. Turn the door handle to the end and unlock the door.
The safe must be fixed on a concrete wall. When the external battery is used for a long time, the battery should be taken out of the battery box.
Extended data:
Safe is a special kind of container. According to its functions, it is mainly divided into fire-proof safe and anti-theft safe, anti-magnetic safe, fire-proof anti-magnetic safe and fire-proof anti-theft safe. Each kind of safe has its own national standard. Most safes on the market are the first two types.
According to different working principles of passwords, anti-theft safes (boxes) can be divided into mechanical insurance and electronic insurance. The former is characterized by cheaper price and more reliable performance. Early safes (boxes) were mostly mechanical ones.
Electronic safe (box) is an electronic lock that applies intelligent control methods such as electronic password and ic card to safe (box). Its characteristic is convenient to use, especially in places where passwords need to be changed frequently, such as hotels.
Security maintenance?
After the surface of the safe is stained with stains, it cannot be scrubbed with chemical solvents, but can be scrubbed with a clean rag and a little detergent. The protruding door bolt and the roller of the drawer can be lubricated with a little lubricating oil (domestic edible oil can also be used), and a little pencil lead powder (graphite) can be injected into the key lock cylinder to make the key easier to insert, insert and rotate. The safe is an anti-theft device. If the sense of responsibility and attention are added in the use process, the anti-theft coefficient of the safe will be greatly improved. ?
Comparison of advantages and disadvantages
Advantages and disadvantages of various passwords in commonly used safes
Among the common safe products in the market, the commonly used passwords are: mechanical, electronic, credit card, fingerprint and remote control password box. , the above types are commonly used. The advantages and disadvantages of different password types are analyzed as follows:
1, the mechanical password is relatively stable and durable, and no power supply is needed. However, the operation method is slow to learn and inconvenient to operate, which requires professionals to modify the password.
2. Electronic password has the advantages of quick operation and simple password modification. Although the price of electronic password lock has decreased and the quality has improved in recent years, it is not as stable and durable as mechanical password because of its complexity.
3. The card lock can open the door of the safe with your own bank card, but the IC card is not easy to use with strong magnetic things!
Fingerprint is hard to find in this world, so fingerprint identification technology is used in safe, which is both confidential and easy to use. However, the opponent's dry humidity requirements are strict! The recognition of finger position is also relatively dull! Even the same finger may not be recognized if it is placed in a different position before it is lost and before it is opened!
5. If it is a safe with high anti-theft performance, the selected safe should not have an emergency key (spare key) hole, because although the emergency key is hidden, if a thief finds it, he can directly use this emergency key to open the safe, which has great security risks. But if you choose this kind of safe, if you really forget the password and key, you can only open it by external force.
Historical exploration
The history of the safe can be traced back to the Middle Ages. In medieval paintings, you can occasionally see a wooden cabinet filled with gold, silver and jewels, which is the prototype of a modern safe. It is a wooden safe with gold, silver and jewels by Louis XV in the18th century, which was copied by the famous French safe manufacturer FICHE-BAUCHE. This kind of safe looks like furniture, and has no special lock, so its security is low.
Until the beginning of19th century 200 years ago, with the growth of social economy, the safe industry began to develop, and specialized lock manufacturers appeared in Europe. 18 18, the United Kingdom Chubb Company was established (19 century Chubb has become a leader in the safe industry). 1825, the French company FICHE-BAUCHE was established ... these manufacturers began to manufacture safes.
The material of the safe has changed from wood to various solid metals, but it is basically based on the tenon joint technology of wood or integral casting, which is similar to the furniture at that time in appearance and technology, and the accuracy of the lock is not high. 19 The lock industry was underdeveloped in the late 1950s. Although the appearance of the safe was changing with each passing day, the accuracy and reliability of the lock did not develop greatly.
65438+At the end of 1960s, Americans invented the lock mechanism and multi-lock technology of safes, which greatly improved the safety performance of safes. In the sixties and seventies, due to the rapid development of semiconductor technology, the industry developed electronic password locks, which were also widely used in various safe products.
Later, LED and LCD digital displays were used in safes, and users' demand for fire protection also gave birth to various fire protection products. The development of fingerprint scanning and identification technology has promoted the application of fingerprint locks in safes, and the popularity of magnetic cards has spawned magnetic card safes ... and the products of safes have also developed from the simplest functions to anti-theft, fire prevention, anti-theft/fire prevention, anti-magnetism, home, business, hotels, firearms, documents/materials and so on.
With the continuous development of various security technologies, the corresponding cracking technologies are also developing, and users are more and more inclined to choose safes that are safer and can protect their property. Therefore, the safe industry is constantly developing, and there are products with higher security, such as face recognition, automatic photo opening, networked alarm safe and so on.
