What is the inner workings of a common padlock like?

How a common padlock works responds to a mechanical system in which external and internal elements intervene, which are combined so that the bolt opens or closes.

  • The mechanism with which a padlock works is something quite simple. It all starts the moment you insert the key.
  • As it enters, the wrench will push the bolts and counter bolts against the springs that are located at the base of these small pieces of metal.
  • When all the bolts and counter bolts are aligned and at the same height, in full coincidence with the cutting line, the cylinder will give way and can be turned without any difficulty, retracting the latch that locks the hook.
  • At that moment, a spring at the base of the longest end of the hook will cause the hook to pop out and the lock to open.

Those who are really interested in knowing how a lock works on the inside, should know that it is possible to acquire transparent locks, which efficiently serve the noble purposes of teaching and learning.

If the case is that you want to be part of the locksmiths guild, this transparent padlock is very useful when learning the trade; but also when applying the knowledge acquired in daily tasks.

What are the parts of a padlock?

To understand a little more about the operation of these security tools, it is necessary to know each of its parts and the function they fulfill within the mechanical system that allows closing and opening the padlock.

  • The key is the first item to consider. It is presented made of metals such as steel, bronze or aluminum; It is the device that allows you to open the padlock.
  • The shape of the key shank and the internal arrangement of the bolts make up a unique and specific code for each padlock; This makes it impossible to open one of these objects without the correct key.

One of the edges is smooth; in the other, the key has teeth and notches of variable shape. They usually have a printed channel that runs through the stem or bit from the tip to the part where it joins the head or handle; this gutter is part of the security code.

  • The body of the padlock: it is generally made of solid and strong metal, such as steel. Sometimes it can be made from iron or steel sheets, which gives it a higher level of security.

The body of the padlock has three holes: two for the movement of the hook and one, in the lower part, for the cylinder.

Padlocks usually have a variable number of small holes on one of their sides, which is where the bolts and their respective springs and counter bolts are housed.

  • The cylinder: it is like the heart of the padlock. A narrow slot that runs from end to end and adapted to the thickness of the key, allows the insertion of the key to open the padlock. The shape of the groove adjusts to the channels that the shank of the wrench may have.
  • The bow, hook or ring: made of steel or other resistant metal, it is the element that embraces the eyebolts or holes in which the padlock is placed.
  • The pins or bolts: they are small moving cylindrical pieces of metal, which conform to the shape of the key and prevent the lock from being opened when it is not the correct one.
  • The counter bolts: they are also small pieces of metal that complement the function of the bolts.
  • The springs: small metal springs located at the base of the set of bolts and counter bolts, which are pushed or contracted by stretching or shrinking as the key passes.
  • The latch: it is a metal device located on the cylinder. Its function is to lock and hold the bow in place when the padlock is closed; when you open the padlock, the latch retracts to release it.

What advantages and disadvantages does the padlock have over the lock?

In principle, it must be said that the padlock is a mobile lock; which makes it practical and versatile.

The padlock turns out to be very useful in those cases in which the space does not leave room for the placement of a fixed lock, be it the mortise type or the superficial ones.

It is true that compared to fixed locks, perhaps the padlock does not reach the level of security that those have; but its practicality, versatility and even its price, somewhat compensate for this disadvantage.
