Description

Safety anti-prizing anti-theft door

Technical Field

The invention relates to the technical field of manufacturing of anti-theft doors, in particular to a safe and reliable anti-prying anti-theft door.

Background

With the continuous development of science and technology, people have continuously improved safety awareness and improved living standard, and more people begin to choose to use the security door as a security door for home entry.

The anti-theft door is called as anti-theft safety door. It has both anti-theft and safety performance. The materials that the burglary-resisting door that the price is different used are also different, but present burglary-resisting door leaf all has the heavier characteristics of self weight at present, and the metal finished piece is like: the condition that burglary-resisting door hinge can produce metal fatigue fracture because of long-time atress, although metal part can not take place whole fracture because of fatigue fracture under most circumstances, slight metal fatigue fracture can cause the deformation of finished piece to produce, and this is that burglary-resisting door uses a period of time after, and its burglary-resisting door hinge can take place the pine to take off, and the reason of the phenomenon of tenesmus appears in the door leaf. The door leaf falls and can lead to the switch of burglary-resisting door not smooth and easy, and the door leaf can't close to the door frame, needs the manpower to lift the door leaf to suitable height just can close to the door frame. If the indoor house decoration floor tile is seriously dropped, a deep arc line is scraped by the indoor house decoration floor tile of the anti-theft door leaf, and therefore the whole house decoration and the user experience are influenced. The existing anti-theft door is easy to close under the pushing of wind and other acting forces, and the door can be locked if a user does not just take a door key. If the door is locked, even if a professional unlocking person is hired, the anti-theft door is extremely difficult to open, and the door frame or the door opening leaf is disassembled to open the door to be locked in most cases, which increases many troubles for our lives.

The current solutions to this technical problem generally employ the following:

1. the technical problem is solved by fixing the loosened hinge again, but the method needs personnel to detect and maintain regularly, and is high in cost, complex in maintenance process and difficult to operate.

2. Chinese patent publication No. CN105155951B discloses an intelligent filtering detection hinge, which detects the loosening phenomenon of the hinge in real time by setting an intelligent electric control structure, so as to quickly find the problem and repair the hinge in time, but this method can only inform the maintainer in time to repair the hinge when the hinge becomes loose, and cannot avoid the loosening phenomenon, and the detection device fails or is powered off, so that there is a situation of misinformation, which causes a waste of time and energy of the maintainer.

3. Chinese patent publication No. CN105201350B discloses a sinking-proof door, in which the gravity of the door leaf is transferred to a Z-shaped plate through a hinge, and the Z-shaped plate transfers the gravity to a wall through an expansion bolt, so as to reduce the probability of loosening the hinge from the door frame, thereby achieving the purpose of controlling the sinking of the door leaf.

4. The chinese patent with publication number "CN 109779477A" discloses a security door preventing the spring back of the lock tongue, and the device is provided with a fingerprint detection screen on the door lock, and the fingerprint detection screen is used for detecting the fingerprint to unlock, thereby avoiding the problem that the user forgets to take the key to cause the user to be unable to get home, but the device has high cost and complex installation, and the electronic equipment is very easy to break down, damage, power failure and the like, and is difficult to be popularized.

The above four solutions are all only to temporarily solve the technical problem, and do not fundamentally solve the technical problem, and still need people to continuously repair, and have the problems of high manufacturing cost, difficulty in popularization and the like. In addition, the existing security door is not provided with a prying-resistant device or the security of the prying-resistant device is not enough, so that the security of the existing security door in the aspect of prying resistance is not good enough.
