Ever wondered how
combination locks
work? Do you know what is inside? It is indeed important to know the basics in the least, for many
households now use these locks as the main form of protection. A combination lock is one of the
hardest locks to unlock or break into unless, of course you have the combination.
In this type of lock a sequence of numbers or symbols is used to open the lock by a combination.
The numbers may be entered using a single rotating dial or a set of dials.
The typical lock has a combination dial that is attached to a lock spindle which runs through
several wheels and a drive cam.
The number of wheels in a lock wheel pack is determined by the number of numbers in the
combination - one wheel for each number. When the right combinations are dialed, all the wheels
and their notches line up entirely. When all the wheels line up, their notches also align to form
a gap, and then the lock is in effect unlocked.
There are many types of this lock. One of the simplest types is the multiple-dial lock which is
often seen in low-security bicycle locks that use several discs with notches cut into them.
Secondly, is the more secure single-dial locks seen in padlocks or safe-locks which usually use a
single dial that interacts with several parallel discs or cams. Another very popular version is of
course the electronic family of locks used in many doors which require the user to enter a numeric
combination or sequence on a keypad for entry.
If you go online, you can purchase almost all of these through catalogs. Most websites offer
various ranges of the famous ones, such as; Combination Padlocks, Dial Combination Padlock,
Combination Baggage Locks, Changeable Cylinder Lock and many more.
