Description

Technical Field

[0001] This utility model relates to the field of security door technology, specifically a multi-functional security door. Background Technology

[0002] The full name of a security door is "anti-theft security door". It combines the functions of anti-theft and security. According to the "General Technical Conditions for Anti-theft Security Doors", a qualified security door cannot be pried open or have a 615 square millimeter opening made in the door leaf, or a 38 square millimeter opening made in the semicircle of 150 square millimeters within 15 minutes using ordinary hand tools such as chisels, screwdrivers, and crowbars, or portable power tools such as electric drills. Furthermore, the locks used on security doors must be special anti-theft door locks with anti-drilling function that have passed the testing of the Ministry of Public Security Testing Center. Security doors can be made of different materials, but only doors that meet the standard testing and obtain a production license for security products can be called security doors.

[0003] Currently, the observation holes on security doors are too far away for most elderly people and children to observe what is happening outside. Opening the door to check outside is dangerous, and the observation range of the holes is also limited. To solve these problems, we have proposed a multi-functional security door. Utility Model Content

[0004] In response to the shortcomings of existing technologies, this utility model provides a multi-functional security door with advantages such as high security. It solves the problems of current security doors where the observation hole is too far away, making it impossible for most elderly people and children to observe the outside situation, and opening the door to check the outside situation is dangerous, as well as the observation range of the observation hole being relatively low.

[0005] To achieve the aforementioned high security objective, this utility model provides the following technical solution: a multi-functional anti-theft door, comprising an anti-theft door frame and a protective plate. An anti-theft door body is hinged inside the door frame. The protective plate is located inside the anti-theft door body. A first latch is fixedly installed on the inner left side wall of the door frame. A first lock is fixedly installed on the left side of the anti-theft door body. A storage box is movably installed on the front of the anti-theft door body. An observation window penetrating the anti-theft door body is fixedly installed on the front of the anti-theft door body. An installation hole is opened inside the anti-theft door body. A protective mesh is fixedly installed inside the installation hole. An anti-theft small door is hinged inside the installation hole. A second lock is fixedly installed on the left side of the anti-theft small door. A second latch is fixedly installed on the inner left side wall of the installation hole. An insertion hole is opened on the front of the anti-theft door body. A snap plate is movably installed inside the insertion hole. A connecting groove is opened on the front of the protective plate. A shaft rod that sleeves the snap plate is fixedly installed at the bottom of the protective plate.

[0006] Preferably, the first door lock is adapted to the first latch, and the second door lock is adapted to the second latch.

[0007] Preferably, the storage box is located below the observation window, and the mounting hole is located below the storage box.

[0008] Preferably, the thickness of the security door is less than the depth of the mounting hole, and the protective net is located on the rear side of the security door.

[0009] Preferably, the anti-theft door body has a placement groove located above the mounting hole inside, and the placement groove is connected to the mounting hole. The protective plate is placed in the placement groove, the width of the anti-theft door is smaller than the width of the mounting hole, and the protective plate is fitted to the anti-theft door.

[0010] Preferably, the bottom of the protective plate has an installation groove, the shaft is located inside the installation groove, and the buckle is tightly attached to the connecting groove.

[0011] Compared with the prior art, this utility model provides a multi-functional security door with the following advantages:

[0012] This multi-functional security door, through its main body, allows people to observe through the observation window when someone calls or knocks from outside. For the elderly or children to check outside, they can turn the second lock to disengage from the second latch, releasing the restriction on the small security door. They can then slowly open the small security door to observe the outside through the protective net. In an emergency, the elderly or children can quickly rotate the latch around the shaft to disengage it from the socket. This causes the protective plate to lose its support point and fall freely along the mounting hole, eventually colliding with the bottom wall of the hole and placing it in front of the protective net, thus shielding the net and protecting the elderly and children. This method achieves a high level of security. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 A multi-functional security door includes a security door frame 1 and a protective plate 14. The security door body 2 is hinged inside the security door frame 1. The protective plate 14 is located inside the security door body 2. A first latch 3 is fixedly installed on the left side wall inside the security door frame 1. A first door lock 4 is fixedly installed on the left side of the security door body 2. The first door lock 4 is compatible with the first latch 3. A storage box 5 is movably installed on the front of the security door body 2. An observation window 6 penetrating the security door body 2 is fixedly installed on the front of the security door body 2. An installation hole 7 is opened inside the security door body 2. The storage box 5 is located below the observation window 6, and the installation hole 7 is located below the storage box 5.

[0019] A protective mesh 8 is fixedly installed inside the mounting hole 7. A small anti-theft door 9 is hinged inside the mounting hole 7. The thickness of the small anti-theft door 9 is less than the depth of the mounting hole 7. The protective mesh 8 is located behind the small anti-theft door 9. A second door lock 10 is fixedly installed on the left side of the small anti-theft door 9. A second latch 11 is fixedly installed on the left side wall inside the mounting hole 7. The second door lock 10 and the second latch 11 are compatible. An insertion hole 12 is opened on the front of the anti-theft door body 2. A snap plate 13 is movably installed inside the insertion hole 12. The snap plate 13 is inserted into the insertion hole 12. The front of the plate 14 has a connecting groove 15. The inside of the anti-theft door body 2 has a placement groove located above the mounting hole 7 and the placement groove is connected to the mounting hole 7. The protective plate 14 is placed in the placement groove. The width of the anti-theft small door 9 is smaller than the width of the mounting hole 7. The protective plate 14 fits snugly against the anti-theft small door 9. The bottom of the protective plate 14 is fixedly installed with a shaft 16 that is sleeved with the buckle plate 13. The bottom of the protective plate 14 has a mounting groove. The shaft 16 is located inside the mounting groove. The buckle plate 13 is tightly attached to the connecting groove 15. The anti-theft door body 2 is thus set up.

[0020] When there are calls or knocks from outside, people can observe through the observation window 6. When the elderly or children want to check the outside situation, they can turn the second door lock 10 to separate it from the second latch 11, releasing the restriction on the security door 9. Then, they can slowly open the security door 9 and check the outside situation through the protective net 8. In case of emergency, the elderly or children can quickly rotate the buckle 13 around the shaft 16 to disengage it from the socket 12. In this way, the protective plate 14 loses its support point and falls rapidly along the mounting hole 7 under free fall, eventually colliding with the bottom wall of the mounting hole 7. This places the protective plate 14 in front of the protective net 8, shielding the protective net 8 and protecting the elderly and children. In this way, a high level of security is achieved.

[0021] In summary, this multi-functional security door, through the security door body 2, allows people to observe through the observation window 6 when there are calls or knocks from outside. When the elderly or children need to check outside, they can turn the second door lock 10 to separate it from the second latch 11, releasing the restriction on the small security door 9. Then, they can slowly open the small security door 9 and observe the outside through the protective net 8. In an emergency, the elderly or children can quickly rotate the latch plate 13 around the shaft 16, disengaging it from the insertion hole 12. This causes the protective plate 14 to lose its support point and fall rapidly along the mounting hole 7, eventually colliding with the bottom wall of the mounting hole 7. This places the protective plate 14 in front of the protective net 8, shielding it and protecting the elderly and children. This method achieves high security and solves the problems of current security door observation windows being too far away, making it impossible for most elderly and children to observe outside, and the inherent danger of opening the door to check outside, as well as the limited observation range of the observation window.
