A lock increases the security of a door by preventing its opening.
In the etymology of the concept of bolt we find the Latin word verucŭlum , which can be translated as "iron bar" . The influence on its form is given by closing .
There are several uses of the concept. The first meaning mentioned in the dictionary of the Royal Spanish Academy ( RAE ) refers to a bar with a letter T design that allows the adjustment and closing of a window or door .
How a lock works
Typically, the bolt has a handle and has two eyebolts or rings. Thanks to its structure and mechanism, it is used to secure the window or door as a pin or latch since it is embedded to make opening impossible.
The lock, in this way, functions as a security mechanism. This is a physical obstacle that makes it difficult to breach the opening in question.
One piece of firearms
In certain firearms, the bolt is a cylinder that houses different elements. This piece makes it possible to close the rear sector of the chamber and houses the firing pin and the cap extractor.
In manual weapons , the bolt is always fixed when firing. Then it must be opened to extract the empty case and closed to place another cartridge in the chamber . In semi-automatic or automatic weapons , however, the bolt moves back and forth between each shot, completing the reloading.
The latches function as locks.
The bolt action rifle
How the bolt of a firearm works can be clearly seen in the so-called bolt-action rifle . In this case, loading is done manually by operating the bolt lever.
The user must open the bolt to load the ammunition and then close it again. After the shot, you have to open the bolt again and the casing is automatically ejected.
A type of operation
It is important to indicate that the word bolt can be used symbolically. This is how it appears in the expression bolt operation .
This is usually the name for a procedure developed by the police or another security force that aims to prevent the escape or departure of a criminal . Its purpose is to establish a perimeter to surround the fugitive, eliminating potential escape routes.
Suppose a thief robs a store and, as he runs away, is seen by a police officer, who notices the situation. This agent notifies the police station and from the headquarters they organize a lock operation, sending several cell phones to patrol a radius of ten blocks around. This maneuver increases the chances of catching the person who committed the robbery .
Bolt in sport
In the sporting field, finally, the tactic that is based on concentrating efforts and resources on strengthening the defense is mentioned as a lock. Soccer teams that seek to impose a lock, for example, focus on taking care of their goal or goal, leaving the offensive side of the game in the background.
While the goal is to increase the chances of not conceding goals, it also minimizes the chances of scoring. If in a team there are eight players dedicated to defending and only two who concentrate on attack , it is very difficult for them to score.
