2. BACKGROUND ART

With the continuous development of science and technology, people's awareness of safety and their living standards have been continuously improving. As a result, an increasing number of people are choosing to use protective doors as their main entrance security doors.


The full name of a protective door is “anti-theft security door”, which combines anti-theft and safety properties. At present, ordinary security doors on the market have a simple structure, use single materials, and are completed through welding and spraying, lacking the ability to prevent explosions or bullet impacts, thus having low security;


Even the current ordinary bulletproof doors only have individual bulletproof functions, and the bulletproof requirements are relatively low. Only the door body is bulletproof, not the entire door, moreover, they do not have explosion-proof or fire-proof functions. Many users now require a door that has bullet-proof, explosion-proof, fire-proof, and anti-theft functions. Currently, this type of ordinary protective door cannot meet the above requirements.
