Interior and exterior door buckles.

1. Examples of inventions.

A primary school student in Sichuan: Mom and Dad often work night shifts, and when they came home late at night, we had already plugged in the door and fell asleep. Sometimes, Mom and Dad scream loudly, but they can't wake us up.

Later, my parents had to lock my sister and me in the house as soon as they left the house. We wanted to go out and have fun, but the door was locked and we couldn't get out.

So I made a "dual-purpose door buckle for inside and outside" (pictured) out of iron sheets, and then used two locks, one nailed to the outside of the door and one nailed to the door frame of the interior. When Mom and Dad left, they locked the door from the outside. The interior was unlocked and we were able to come and go as we pleased.

When we went to sleep, we locked the door from the inside. Mom and Dad come back from work and can unlock the door from the outside.

Automatic carton The cover of this carton is usually covered, which can prevent dirt and dust from entering.

When it is finished, it is back in place as soon as it is covered.

This automatic carton is best suited for toilet toilet sheets. The size of the carton can be designed according to your own needs.
