[0004] When the aluminum alloy door body and door frame are close together, the existing aluminum alloy door lock can only be manually operated to lock one part of the aluminum alloy door lock with the other part, that is, manually press the door lock button embedded in the aluminum alloy door body and push the door lock pin into the groove in the door frame to complete the door locking action. When opening the door, it is also necessary to manually press the button and use a large force to pull the door lock pin out of the groove. The locking and unlocking of traditional aluminum alloy door locks are very inconvenient, and people often forget to lock the aluminum alloy door body. In addition, frequent use and operation of aluminum alloy door locks will not only cause damage to people's fingers, but also frequent friction will cause damage to the button and the door lock groove, and ultimately fail to achieve the expected door locking effect. Furthermore, ordinary door locks are not tightly wrapped in a shell when in use. Long-term work or working in a harsh environment will cause a lot of dust to enter the structure, thereby blocking the button slide slot and causing the door to be unable to lock normally.
