Description
Technical Field
[0001] The utility model relates to the technical field of anti-theft doors, in particular to a ventilated anti-theft door. Background Art
[0002] With the changes in modern residential design, some units have problems with poor ventilation, especially in humid areas or in tightly sealed buildings. In order to improve indoor air quality and reduce moisture and mold growth, ventilation needs are particularly important. Ventilated security doors came into being, aiming to achieve the dual functions of anti-theft and ventilation through design innovation.
[0003] When the ventilation windows are opened, the indoor air can form convection with the outside air through the ventilation windows, thereby improving the indoor air quality and reducing moisture and mold growth. This convection effect is particularly suitable for apartments with poor ventilation conditions or humid areas. Some ventilated security doors are also designed with adjustable ventilation windows. Users can adjust the opening size of the ventilation windows as needed to control the indoor air circulation. The ventilated security doors are made of strong materials such as high-strength steel or aluminum alloy to ensure the strength and durability of the door leaves. At the same time, the grid of the ventilation window is also made of a material that is not easily damaged to improve the anti-theft performance.
[0004] However, the existing filter is prone to accumulate dust and impurities. Long-term dust accumulation can easily block the air inlet, affecting the ventilation effect of the filter. Since a cross screwdriver is required to remove the filter, the screws that fix the filter must be found and loosened. After loosening all the fixing screws, the filter is gently removed from the ventilation window. This operation is more cumbersome and the screws may be lost, resulting in a poor user experience and reducing the cleaning efficiency of the filter. In addition, since a fence is set on the outer door of the anti-theft door, it can provide a certain degree of privacy protection, but compared to a completely closed door, the privacy is still reduced. Utility Model Content
[0005] It solves the problem of difficulty in removing the filter, improves the user experience, and enhances privacy and security.
[0006] In view of the above-mentioned problems of removing the filter screen and protecting privacy, the present utility model is proposed.

Example 2
[0030] Reference Figure 4-7 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a plurality of linearly distributed cylinders 9 are fixedly connected between the two ends of the inner wall of the rectangular hole, and the cylinder 9 is used for the shutter 10 to rotate along the cross section of the cylinder 9 as the center of the circle. The outer wall of the cylinder 9 is rotatably connected to the inner wall of the shutter 10, and a circular hole is provided at one end of the rectangular plate 19 to facilitate the sliding of the outer wall of the connecting rope 11. A plurality of linearly distributed limiting plates 12 are fixedly connected to the outer wall of the connecting rope 11. The diameter of the limiting plate 12 is larger than the circular hole. The limiting plate 12 is used to push one end of the blade of the shutter 10 to rotate along the cross section of the cylinder 9 as the center of the circle.
[0031] A mounting groove is provided at the top of the rectangular hole, and a pulley 13 is fixedly connected to the bottom of the mounting groove. The pulley 13 is used to transmit the connecting rope 11 to reduce friction resistance. The outer wall of the pulley 13 is slidably connected to the outer wall of the connecting rope 11. A circular groove is provided at one end of the mounting groove, and a rotating column 14 is slidably connected to the inner wall of the circular groove. The rotating column 14 is used to drive the connecting rope 11 to rise and fall.
[0032] A stopper is provided at the bottom end of the rotating column 14, which limits the position of the rotating column 14. A second spring 15 is connected between the stopper and the bottom of the circular groove, and the second spring 15 is used to push the rotating column 14. A fixing plate 16 is fixedly connected to the outer wall of the rotating column 14, and the fixing plate 16 is used to limit the position of the connecting rope 11. Two mirror-distributed card grooves 17 are provided on the inner wall of the mounting groove. The cross-section of the card groove 17 is "L"-shaped, which is used to clamp the limit block 18.
