Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a lock that is easy to assemble. Background Art

[0002] A lock is a device used to protect property or restrict access to a specific area. They are usually made of metal and are opened and closed mechanically, electronically or electrically. The main components of a lock include a lock cylinder, a lock body, a key (or password), etc. The function of a lock is to prevent unauthorized people or objects from entering a protected area or obtaining protected property. They are widely used in home, commercial, industrial and automotive fields. Depending on the usage scenario and functional requirements, there are different types of locks, including door locks, drawer locks, padlocks, combination locks, fingerprint locks, etc.

[0003] At present, when using locks, most locks can prevent unauthorized people or objects from entering the protected area or obtaining the protected property, and avoid the loss of objects; however, due to the complicated internal structure of the lock, when installing the lock, more parts will make it more time-consuming and laborious for the operator to assemble the lock. At the same time, when some parts inside the lock need to be replaced, it is more complicated to disassemble the parts inside the lock. The lock that is difficult to repair will be directly replaced with a new one, which makes it very inconvenient to assemble the lock. In view of this, we have introduced a lock that is easy to assemble. Summary of the invention
