Description
Technical Field
[0001] This utility model relates to the field of mailbox frame technology, specifically a secure mailbox frame. Background Technology
[0002] Mailbox frames are tools that help postmen put letters or other documents into rooms, and are usually installed on the front door of a house.
[0003] However, the existing mailbox frames have certain security risks. First, people outside can see into the room through the gap, which doesn't provide enough privacy. Second, thieves could use the gap to insert tools such as bent wires into the room and then open the door by turning the handle on the inside. Utility Model Content
[0004] The purpose of this invention is to provide a secure mailbox frame to solve the problems mentioned in the background art.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] A secure mailbox frame includes a main body and an outer window. The main body includes a connecting sleeve, and the connecting sleeve has a through groove on its side. A pair of first openings are located on one side of the connecting sleeve, with the pair of first openings positioned on both sides of the through groove. The outer window includes an outer frame, which is mounted on one side of the connecting sleeve. The outer frame has an inlet on its side that communicates with the through groove. The outer frame also has a pair of second openings on its side that communicate with the first openings. Limiting rods are installed inside each of the second openings. An outer baffle is hinged to the side of the outer frame, and limiting plates are installed on both sides of the outer baffle. Each limiting plate has a limiting groove, and the limiting plate slides within the first and second openings. The limiting rods slide within the limiting grooves.
[0007] The beneficial effect of adopting the above-mentioned further solution is that the outer baffle has the ability to rotate. While it rotates, the limiting plate also moves within the first and second openings. After it moves a certain distance, the limiting rod will abut against one end of the limiting groove. At this time, the outer baffle can no longer rotate, and its opening and closing angle reaches its maximum value. Since the limiting groove is arc-shaped and the arc is less than 45 degrees, the opening and closing angle of the outer baffle is much less than 90 degrees. This angle will not affect the delivery of letters, but it is not enough for larger lock-picking tools to pass through. It can also limit the movement range of smaller lock-picking tools, making it impossible for lock-picking tools to unlock from the inside of the door. Finally, the small opening and closing angle makes it impossible for outsiders to observe the situation inside the room.
[0008] Furthermore, it also includes an inner window, which includes an inner frame. The inner frame is installed on the other side of the connecting sleeve. The side of the inner frame is provided with an outlet that communicates with the through slot. An inner baffle is hinged to the side of the inner frame.
[0009] The advantage of adopting the above-mentioned further solution is that by using the inner baffle to cover the other side of the channel, the view of external personnel is further blocked.
[0010] Furthermore, the side of the outer frame is rotatably connected to a first pin via a torsion spring near its bottom surface, and the bottom surface of the outer baffle is mounted on the outside of the first pin.
[0011] Furthermore, the side of the inner frame is rotatably connected to a second pin via a torsion spring near its bottom surface, and the bottom surface of the inner baffle is mounted on the outside of the second pin.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the torsion spring enables the outer baffle and inner baffle to reset after the external force is lost, thereby automatically blocking both sides of the through groove.
[0013] Furthermore, both the bottom and top surfaces of the through groove are sloped, and the height of the through groove near the outer frame end is greater than the height of the through groove near the inner frame end.
[0014] The advantage of adopting the above-mentioned further solution is that the downward-sloping channel can further block the view of outsiders.
[0015] Furthermore, the inside of the through groove is also connected to several shielding strips.
[0016] The beneficial effect of adopting the above-mentioned further solution is that each shielding strip is a flexible, wide strip, and the shielding strips are not connected to each other. When outsiders attempt to use objects such as mirrors to reflect the situation inside the room, the shielding strips can block the reflection of the mirrors.
[0017] Furthermore, both the outer baffle and the inner baffle are opaque.
[0018] The beneficial effect of adopting the above-mentioned further solution is that by setting the outer and inner baffles as opaque panels, external personnel cannot observe the indoor situation through the outer and inner baffles.
[0019] Compared with the prior art, the beneficial effects of this utility model are: the security mailbox frame, by limiting the opening and closing angle of the outer baffle to be much less than 90 degrees, makes the size of the opening insufficient for a lock-picking tool to pass through, and can limit the movement range of the lock-picking tool. Finally, the opening and closing angle of much less than 90 degrees is insufficient for outsiders to see the situation inside the room through the opening, so as to protect the user's privacy.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0026] Please see Figure 1 - Figure 4This utility model provides a technical solution: a secure mailbox frame, including a main body 100 and an outer window 200. The main body 100 includes a connecting sleeve 1001, and the side of the connecting sleeve 1001 is provided with a through groove 1002. A pair of first openings 1003 are provided on one side of the connecting sleeve 1001, and the pair of first openings 1003 are located on both sides of the through groove 1002. The outer window 200 includes an outer frame 2004, which is installed on one side of the connecting sleeve 1001. The side of the outer frame 2004 is provided with an inlet 2005 communicating with the through groove 1002. The side of the outer frame 2004 is also provided with a pair of second openings 2006 communicating with the first openings 1003. Limiting rods 2007 are installed inside each of the second openings 2006. An outer baffle 2001 is hinged to the side of the outer frame 2004, and limiting plates 2002 are installed on both sides of the outer baffle 2001. The limiting plates 2002 have limiting grooves. In section 2003, the limiting plate 2002 slides within the first opening 1003 and the second opening 2006, and the limiting rod 2007 slides within the limiting groove 2003. The outer baffle 2001 has the ability to rotate. While it rotates, the limiting plate 2002 also moves within the first opening 1003 and the second opening 2006. After it moves a certain distance, the limiting rod 2007 will abut against one end of the limiting groove 2003. At this time, the outer baffle 2001 can no longer rotate, and its opening angle reaches its maximum value. Since the limiting groove 2003 is arc-shaped and the arc is less than 45 degrees, the opening angle of the outer baffle 2001 is much less than 90 degrees. This angle will not affect the delivery of letters, but it is not enough for larger lock-picking tools to pass through, and it can limit the movement range of smaller lock-picking tools, making it impossible for lock-picking tools to unlock from the inside of the door. Finally, the small opening angle makes it impossible for outsiders to observe the situation inside the room.
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0028] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a security mailbox frame, in which a number of shielding strips are connected inside the through groove 1002. Each shielding strip is a flexible strip-shaped wide strip, and the shielding strips are not connected to each other. When outsiders attempt to use objects such as mirrors to reflect the situation inside the room, the shielding strips can block the reflection of the mirror.
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0030] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a secure mailbox frame, including a main body 100 and an outer window 200. The main body 100 includes a connecting sleeve 1001, and the side of the connecting sleeve 1001 is provided with a through groove 1002. A pair of first openings 1003 are provided on one side of the connecting sleeve 1001, and the pair of first openings 1003 are located on both sides of the through groove 1002. The outer window 200 includes an outer frame 2004, which is installed on one side of the connecting sleeve 1001. The side of the outer frame 2004 is provided with an inlet 2005 communicating with the through groove 1002. The side of the outer frame 2004 is also provided with a pair of second openings 2006 communicating with the first openings 1003. Limiting rods 2007 are installed inside each of the second openings 2006. An outer baffle 2001 is hinged to the side of the outer frame 2004, and limiting plates 2002 are installed on both sides of the outer baffle 2001. The limiting plates 2002 have… The device includes a limiting groove 2003, a limiting plate 2002 that slides within the first opening 1003 and the second opening 2006, a limiting rod 2007 that slides within the limiting groove 2003, and an inner window 300. The inner window 300 includes an inner frame 3001, which is installed on the other side of the connecting sleeve 1001. The side of the inner frame 3001 has an outlet 3002 that communicates with the through groove 1002. An inner baffle 3003 is hinged to the side of the inner frame 3001. The device is embedded in the door and is positioned away from the door lock and close to the bottom of the door. When the postman delivers the letter, he holds the top surface of the outer baffle 2001 and flips it over, then inserts the letter. Because the letter is made of paper, it has the ability to bend, so the letter can push open the inner baffle 3003 and enter the room. After the pressure of the letter is released, the torsion spring causes the outer baffle 2001 and the inner baffle to return to their original positions, thereby automatically covering both sides of the through groove 1002.
[0031] Specifically, the working principle of this type of secure mailbox frame is as follows: In use, the device is embedded in the door, positioned away from the lock and near the bottom of the door. When the postman delivers the mail, he grasps the top surface of the outer baffle 2001 and flips it over, then inserts the letter. Because the letter is made of paper, it has the ability to bend, allowing it to push open the inner baffle 3003 and enter the room. After the pressure from the letter is released, the torsion spring causes the outer baffle 2001 and the inner baffle to return to their original positions, automatically covering both sides of the through slot 1002. After the outer baffle 2001 moves a certain distance... When the limiting rod 2007 abuts against one end of the limiting groove 2003, the outer baffle 2001 can no longer rotate, and its opening angle reaches its maximum value. Since the limiting groove 2003 is arc-shaped and the arc is less than 45 degrees, the opening angle of the outer baffle 2001 is much less than 90 degrees. This angle will not affect the delivery of letters, but it is not enough for larger lock-picking tools to pass through, and it can limit the movement range of smaller lock-picking tools, making it impossible for lock-picking tools to unlock from the inside of the door. Finally, the small opening angle makes it impossible for outsiders to observe the situation inside the room.
