Technical Field
[0001] This utility model belongs to the field of security door technology, specifically relating to a security door with a ventilation window. Background Technology
[0002] Security doors are now a common feature in almost every household. They are made of sturdy materials and have complex locks, which can effectively prevent thieves from breaking in and protect people's lives and property. With the advancement of technology, some security doors are also equipped with smart functions, such as fingerprint unlocking and password unlocking.
[0003] Nowadays, people have increasingly higher requirements for indoor air quality. When ventilating at home, a phenomenon occurs: if only windows are opened, air cannot circulate, resulting in a weak breeze. However, if the door is opened, air circulates, creating a stronger breeze and better ventilation. But opening the door can easily expose the privacy of the house and pose certain security risks. Therefore, we propose a security door with ventilation windows to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a security door with ventilation windows. When in use, the two mounting plates are unfolded and ventilation is provided through two air outlets. Due to the setting of the baffle, the situation inside the house cannot be directly seen from outside, thus protecting the user's privacy and preventing outsiders from entering, thereby protecting the user's safety.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0028] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] like Figure 1-5 As shown, this utility model discloses a security door with a ventilation window, comprising:
[0030] The door frame 1 has a door body 11 hinged inside it. A locking device 12 is provided between the door body 11 and the door frame 1. The locking device 12 can be any one of a mechanical door lock, a fingerprint lock, or a combination lock. All three locking devices 12 can lock the door body 11.
[0031] An opening 13 is provided in the middle of the front side of the main door 11;
[0032] Mounting frame 2 is fixedly installed inside opening 13;
[0033] Assembly frame 3 is fixedly installed inside the mounting frame 2. Air outlets 31 that communicate with the interior of the assembly frame 3 are opened on the front of the left and right sides of the assembly frame 3.
[0034] Baffle 4 is vertically installed in the center of the assembly frame 3.
[0035] Two rotating shafts 5 are provided, which are arranged to rotate left and right and are mounted inside the front side of the assembly frame 3. Assembly plates 51 are fixedly installed around the two rotating shafts 5. Flexible sealing elements are sleeved around the assembly plates 51. In this way, when the assembly plates 51 rotate, the gap between the assembly frame 3 and the assembly plates 51 can be kept sealed. When the assembly plates 51 close the assembly frame 3, the sealing effect can also be increased by the flexible sealing elements.
[0036] The drive mechanism 6 is located on the top of the assembly frame 3 and is used to drive the two rotating shafts 5 to rotate synchronously in opposite directions. Specifically, the drive mechanism 6 includes an assembly box 61. The upper ends of the two rotating shafts 5 extend out of the assembly frame 3 and are fixedly installed with worm gears 621. The assembly box 61 is fixedly installed at the top center of the assembly frame 3. The two worm gears 621 are located inside the assembly box 61. The inner walls of the front and rear sides of the assembly box 61 are rotatably equipped with a connecting shaft 62. The connecting shaft 62 is located between the two worm gears 621. A worm 63 is fixedly installed around the connecting shaft 62. The two worm gears 621 mesh with the worm 63. A motor 65 is fixedly installed on the rear side of the assembly box 61. The motor 65 is electrically connected to the controller 7.
[0037] like Figure 1 As shown, in the initial state, both assembly plates 51 are tilted, completely sealing the front of the assembly frame 3. Because the connection between the worm gear 621 and the worm 63 is self-locking, the two assembly plates 51 cannot be opened. When ventilation is required, the user controls the motor 65 via the controller 7 to rotate the connecting shaft 42. Since the two worm gears 621 are located on the left and right sides of the worm 63 respectively, their rotation directions are opposite. Therefore, the worm 63 simultaneously drives the two worm gears 621 to rotate, causing the two assembly plates 51 to adjust their angles synchronously until the two assembly plates 51 are aligned with the baffle 4. The two air outlets 31 are vertically aligned, allowing air from inside the room to flow through the assembly frame 3. Outside the door, because the two air outlets 31 are located on the left and right sides and are equipped with baffles 4, there is a blind spot, preventing a direct view of the room and protecting privacy. While ventilating, it also prevents outsiders from entering. Users can control the motor 65 to start and stop the two assembly plates 51 at set times via the controller 7. After ventilation, users can manually stop the two assembly plates 51 via the controller 7 to restore the room to its original state. The operation is simple and convenient.
[0038] Controller 7 is installed on the rear side of the door body 11, and the drive mechanism 6 is electrically connected to controller 7.
[0039] The baffle 4 divides the internal space of the assembly frame 3 into a left cavity and a right cavity. Both the left and right cavities are fixedly installed with mesh screens 8 on their rear sides. The mesh screens 8 can effectively prevent mosquitoes from outside from entering the house.
[0040] A smoke sensor 9 is installed on the front side of the door body 11, and an air detector 91 is installed on one side of the baffle 4. Both the smoke sensor 9 and the air detector 91 are electrically connected to the controller 7. When a fire occurs outside and produces dense smoke, the smoke sensor 9 will detect it and issue a corresponding warning to the user, thus improving safety. The air detector 91 can detect air quality during ventilation and will remind the user to close the doors and windows and stop ventilation when the air quality is poor, thus improving the user experience.
[0041] The device is used as follows:
[0042] When ventilation is not required, the two mounting plates 51 together completely seal the front of the mounting frame 3. When ventilation is needed, the operator starts the motor 65 via the controller 7. The motor 65 drives the connecting shaft 62 to rotate, which in turn drives the two worm gears 621 to rotate via the worm 63. The two worm gears 621 rotate in opposite directions, which in turn drives the two mounting plates 51 to open synchronously until they are perpendicular to the baffle 4. In this way, the two air outlets 31 are fully open to allow air to flow out. From the outside perspective, due to the setting of the baffle 4, there is a blind spot, and it is impossible to directly see the situation inside the room through the air outlets 31 on both sides, thus protecting the privacy inside the room. At the same time, it can also prevent outsiders from entering when the doors are wide open during ventilation, thus playing a security role. Subsequently, the motor 65 can be started at a timer via the control terminal of the controller 7 or manually. The output shaft of the motor 65 rotates in the other direction, driving the two mounting plates 51 to fully close and return to the initial state. It is simple and convenient to use.
[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
