Padlocks are the oldest and largest family of locks in the world. It can be said that other locks are derived from padlocks. Even if the padlock is a primitive lock, there are many types of padlocks! Many netizens asked how to open the padlock on the Internet, and the answers were varied. Today, the author will introduce the specifications and models of padlocks to you? What kind of padlocks are there? How to open a padlock? Let’s take a look!
There are many varieties and specifications of padlocks. The specification of the lock is generally determined according to the total width of the lock cylinder, the use of the lock is determined according to the height-width ratio of the lock beam, and the series of lock products are determined according to the opening methods of the padlock, such as straight opening, horizontal opening, top opening, and lock opening. of.
The padlocks that are often used are generally opened in two ways: straight opening and horizontal opening.
At this stage, the stainless steel shell locks made in Shanghai also use the horizontal opening method, and there are fewer opening methods.
In other words, a lock that can be opened without turning when the key is inserted into the key slot of the anti-theft cylinder is called top opening. This type of padlock is especially suitable for openers who are carrying a baby or who are not suitable for learning to put down objects. The term “padlock” refers to a lock that requires two keys to open. It has strong safety performance and must be applied to both. Two people open the locks at the same time, such as warehouses, silver vaults, etc.
In addition to the classification according to the starting method (straight opening, horizontal opening, top opening, and lock), we can also classify according to the structure of the padlock. There are generally the following categories:
1. The marble structure padlock.
This type of lock uses cylindrical marbles to set obstacles in the lock body, so that the anti-theft lock cylinder cannot be rotated, so as to achieve the actual effect of the lock. The marble structure is also one of the common structures of locks. There is a kind of lock cylinder that is folded up with copper sheets, which gives people a strong and firm feeling. It is called a thousand-layer lock, but its internal structure is also a marble structure, so it is also a marble structure padlock.
2. Blade structure padlock.
This type of lock uses block metal materials of different styles as obstacles. This type of structure is often used in zinc alloy materials or aluminum alloy locks.
3. Magnetic construction padlock.
According to the basic principle of magnetic interference, the software of the magnetic anti-theft lock cylinder system is selected. A constant magnetic metal baffle is installed between the anti-theft lock cylinder slot and the commercial insurance pin. The key does not directly contact the commercial insurance pin. When the slotless magnetic key is stably inserted into the anti-theft lock When the core groove rotates, the key touches the metal material baffle, the repulsive force is strong, and the lock is very easy to open. In addition, the basic principle of magnetic attraction is also used, the metal material plate is tightened, and the lock is opened according to the torsion spring.
4. Even the structural padlock is broken.
It consists of a main lock and an auxiliary lock, and the main lock and the auxiliary lock have the function of mutual protection. Connecting 2 secondary locks is to lock the main lock. Only by opening and taking out 2 secondary locks, the main lock can be opened.
5. Construction padlock.
Install the double rocker mechanism on the lock cylinder casing, the hole is connected with the slot, can be moved and rotated, the data disk is connected with the rotator, the rotator is equipped with teeth or camshaft metal material blades, which can be rotated and moved, just pull out number, the lock can be opened by itself, this type of lock does not have a key.
Before the practice of unlocking skills: the first thing to do is to remove the lock, then master the internal structure of various locks, integrate the basic principles of shift opening, and further increase the impression of lock opening.
How to open a padlock – way one.
Bump lock unlocking method: copper sheet and fine iron wire, copper sheet is like a pen cap, one end is folded at 90°, the rotation force of the lock cylinder is tripped, and the iron wire is swept back and forth around the marble of the lock cylinder, and good luck can be opened.
How to open a padlock – way two.
Take a malleable hard wire (keychains are great), bend a small section at about a 135° angle, and reach deep into the lock cylinder (must get more and more training, a little tough).
How to open a padlock – way three.
A normal padlock has a lock center. In addition to the key hole, there are also many round holes on the lock core. This kind of round hole corresponds to the many round holes on the lock cylinder, and a torsion spring and two copper marbles with different aspect ratios can be placed.
After the key** is removed, because of the different tooth positions, the aspect ratio of the two marbles is also different. If the boundaries of the two marbles in all the holes are the same as the circle on the lock center, the lock center can rotate in the lock body, so the lock is opened. This is also the general principle of padlocks. If the padlock key is lost, you can buy a universal key that can open all kinds of padlocks.
How to unlock the three-ring padlock:
Among the marbles on the three-ring lock, there is a type called I-shaped marble. Marbles of this type are not easy to turn, but that doesn’t mean they can’t be moved. For these hardworking lockpickers, this is not too difficult. There are I-shaped beads in the lock, and there is usually at least one marble that still has to be standardized, in other words, it is very rare to have more than four I-shaped beads. The purpose of applying the standard marble is to align the lock cylinder with the two ends of the marble eye, so that the insertion and extraction of the key is smoother.
When the I-shaped marble is extended due to the rotation of the lock core, the I-shaped head will press against the shoulder of the marble eye instead of extending, that is, retracting the marble eye. To deal with this problem, the rotational force of the pendulum must be taken with special care, and the marbles add mild rotational working pressure. The case of marbles is not detected with a single hook, and you can feel the difference in timidity between standard marbles and I-shaped marbles. To lift the I-shaped marble completely, it is necessary to understand the moderate review (in the case of the three-ring lock playback, because the lock itself is malleable, the range of the review is not easy to grasp). There is a kind of “push ten times three”, {make a proportion, push 10 degrees to the opening position, and look back at 3-4 degrees}. Release the pressure and even the rotation force of the lock core in the opposite direction, so that most of them get rid of the obstruction of the upper marble eye and retract. However, the lock core has been reversed, which is also very likely to fall off and lock the previously dialed marbles again.
