Description

Technical Field

[0001] This utility model relates to the field of armored door structure technology, specifically to an armored door that facilitates ventilation. Background Technology

[0002] Armored doors are a type of door that can be matched with interior decoration. Generally, the user can make a request. The anti-theft performance is achieved by using a steel plate in the middle. Manufacturers can choose different colors, woods, lines and patterns according to the user's requirements to integrate with the interior decoration, which is no longer as cold and uncoordinated as steel doors.

[0003] In the use of armored doors, ventilation is often poor, and air can only be circulated by opening the door. When closed, ventilation is not possible. Traditionally, this is achieved by adding a security door with a mesh, but this method is costly and inconvenient to use. Utility Model Content

[0006] The lifting protective plate is provided with a limiting plate on the side away from the rack structure, and the limiting plate is provided with multiple limiting holes. The armored door body is provided with a positioning rod that matches the limiting holes.

[0007] Furthermore, the armored door body is provided with a first filter structure and a second filter structure at the front and rear, respectively, to cooperate with ventilation holes.

[0008] Furthermore, the first filter structure and the second filter structure include a central filter structure, with a first support protective net and a second support protective net on both sides of the central filter structure, and support rod structures for supporting the first support protective net and the second support protective net are provided at the front and rear of the first filter structure and the second filter structure.

[0009] Furthermore, the lifting protective plate is provided with limiting slide bars on both sides at the front and back, and the armored door body is provided with limiting slide grooves on both sides to cooperate with the limiting slide bars.

[0010] Furthermore, the lifting protective plate is inlaid with a first sealing strip structure on the front and rear sides of the top, and the limiting slide is inlaid with multiple second sealing strip structures.

[0011] The advantages of this ventilated armored door compared to existing technologies are as follows: This invention, by setting a liftable protective plate structure, allows for the opening of ventilation holes, thus enabling the selection of whether or not to ventilate, achieving ventilation while the armored door is closed.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1-5An armored door designed for ventilation includes an armored door body 1. The bottom of the armored door body 1 has a ventilation hole 2. The armored door body 1 has an internal cavity structure 5. A lifting protective plate 6 is installed within the cavity structure 5, and a rack structure 7 is located on one side of the lifting protective plate 6. A gear 8, which meshes with the rack structure 7, is rotatably installed inside the armored door body 1. The gear 8 has a torsion handle 9 extending to the outside. In actual use, the torsion handle is generally located inside the armored door body 1. A detachable housing for the cavity structure 5 is also required, secured with bolts. This is a common structure and will not be elaborated further. This facilitates regular maintenance. When in use, twisting the handle 9 rotates the gear 8, which, in conjunction with the meshing rack structure 7, raises the lifting protective plate 6. When ventilation is needed, the lifting protective plate 6 is raised to ensure ventilation of the armored door body 1. When ventilation is not needed, the lifting protective plate 6 is lowered to ensure the armored door body 1 is sealed and protected.

[0020] The lifting protective plate 6 is provided with a limiting plate 10 on the side away from the rack structure 7. The limiting plate 10 is provided with multiple limiting holes 11. The armored door body 1 is provided with a positioning rod 12 that matches the limiting holes 11. The positioning rod 12 can be pulled out. If it is to be prevented from being lost, it can be limited and set on the armored door body 1. For example, a limiting groove is set in the armored door body 1, and a limiting block is set on the positioning rod 12 to ensure that the positioning rod 12 can be inserted and removed back and forth. The multiple limiting holes 11 can ensure that the lifting protective plate 6 is fixed and positioned after it is raised or lowered. When it is raised or raised normally, pressing the positioning rod 12 into the limiting hole 11 can ensure that the lifting protective plate 6 is positioned. After it is lowered and sealed, pressing the positioning rod 12 into the limiting hole 11 can ensure that the bottom of the lifting protective plate 6 is positioned.

[0021] The armored door body 1 is provided with a first filter structure 3 and a second filter structure 4 at the front and rear, respectively, to cooperate with the ventilation holes 2. The first filter structure 3 and the second filter structure 4 include a central filter structure 15. The central filter structure 15 is provided with a first support protective net 16 and a second support protective net 17 on both sides. The first filter structure 3 and the second filter structure 4 are provided with support rod structures 18 at the front and rear for supporting the first support protective net 16 and the second support protective net 17. The first filter structure 3 and the second filter structure 4, which are set up inside and outside, can filter some mosquitoes. The first support protective net 16, the second support protective net 17 and the support rod structure 18 can ensure the structural strength. The central filter structure 15 can filter mosquitoes. It can be selected with 100-150 mesh to ensure ventilation effect while filtering.

[0022] The lifting protective plate 6 is provided with limiting slide strips 13 on both sides, front and back. The armored door body 1 is provided with limiting slide grooves 14 on both sides to cooperate with the limiting slide strips 13. The lifting protective plate 6 is provided with first sealing strip structures 19 on the front and back sides of the top. The limiting slide strips 13 are provided with multiple second sealing strip structures 20. The first sealing strip structure 19 and the second sealing strip structure 20 can provide a basic sealing effect when the lifting protective plate 6 falls. At the same time, a sealing strip can also be provided at the bottom of the lifting protective plate 6 to further ensure the sealing effect.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
