Description

Technical Field

[0001] This utility model relates to the field of entrance door technology, specifically to an assembled steel entrance door. Background Technology

[0002] Steel entrance doors are a common type of residential door, with multiple functions and features. They are usually made of high-quality steel and have functions such as fire resistance and burglar resistance. Depending on the needs of use, some entrance doors are equipped with ventilation windows for easy ventilation.

[0003] The ventilation windows on existing steel entrance doors are mostly installed and fixed to the door body with screws. After long-term use, dust and other impurities adhere to the ventilation windows, making them inconvenient to clean. This affects both the ventilation effect and the aesthetics. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-6 This utility model provides an embodiment of a prefabricated steel entrance door, comprising a door body 1 and a door frame 2. The main materials can be cold-rolled steel plate, galvanized steel plate, and zinc alloy steel plate, which are relatively mature technologies and will not be elaborated upon here. One end of the door body 1 is hinged to the door frame 2, while the other end is connected via a door lock device 3 (which can be a mechanical lock or a fingerprint lock, etc., assembled according to usage needs to ensure security; this is also a relatively mature technology and will not be elaborated upon here). To ensure ventilation and prevent dust, insects, etc., from entering the room through the entrance door, a locking frame 6 is provided on the door body 1. Figure 2 As shown in the figure, this is one side of the interior. Inside the card frame 6, a placement mechanism is installed via an installation mechanism. The placement mechanism contains a filter assembly, ensuring airflow and facilitating regular disassembly and replacement. Meanwhile, the card frame 6... Figure 2 As shown, disassembly should be performed from the indoor side to improve safety.

[0024] Please see Figures 1-6 To ensure air circulation and prevent insects from entering the room, the placement mechanism includes a placement frame 10 inside the card frame 6. The placement frame 10 has a sliding mounting groove 15, and a sliding mounting slider 14 slides within the mounting groove 15. A connecting plate 4 is welded together between the four mounting sliders 14. To facilitate ventilation, through holes 13 are equidistantly provided on both the connecting plate 4 and the placement frame 10. An activated carbon plate 11 and a dustproof net 12 of the filter assembly are arranged sequentially between the connecting plate 4 and the placement frame 10. The dustproof net 12 is located on the side closest to the outside, which can effectively block dust, insects, etc., and can also absorb and purify odors. This is a relatively mature technology and will not be described in detail here.

[0025] Please see Figures 1-6 To facilitate the installation and disassembly of the connecting plate 4 and the placement frame 10, allowing for periodic replacement or cleaning to ensure filtration efficiency and ease of assembly, the top and bottom of the card frame 6 are equidistantly provided with guide grooves 7 for the installation mechanism. Positioning holes 9 are provided inside the guide grooves 7. The top and bottom of the placement frame 10 are provided with sliding cavities 20 for the reset assembly. A moving plate 18 is slidably mounted inside the cavities via a spring 19. A positioning block 16, matching the positioning hole 9, is fixedly welded to the end of the moving plate 18 away from the spring 19. The positioning block 16 slides out of the sliding cavity 20, and a convenient mounting bracket is provided on the side wall of the positioning block 16. The sliding groove 17 can be moved by inserting tools such as levers or flathead screwdrivers, and the positioning block 16 can be moved to easily remove it from the positioning hole 9. In order to ensure aesthetics, the guide groove 7 of the card frame 6 has connecting sealing grooves 8 on both sides. The connecting sealing groove 8 has a sealing plate 5, which can easily seal the guide groove 7. In order to ensure the connection effect and facilitate disassembly, the sealing plate 5 has a rubber pad that matches the connecting sealing groove 8, or has a fixing magnet to assist in attraction and fixation. The corresponding sealing plate 5 has a groove on its side wall for easy snapping (not shown in the figure). It is a relatively mature technology and will not be described in detail here.

[0026] Working Principle: In use, the dustproof net 12 and activated carbon plate 11 are placed into the placement frame 10 in sequence. Then, the connecting plate 4 is connected to the placement frame 10 by the mounting slider 14 in conjunction with the mounting groove 15. Then, the positioning block 16 is pressed by the actuating groove 17, which moves the moving plate 18 within the sliding cavity 20. The spring 19 contracts under force to store potential energy, and then the positioning block 16 can be inserted into the guide groove 7. After insertion, the positioning block 16 loses its limiting position and resets under the potential energy of the spring 19. The positioning block 16 enters the positioning hole 9, and together with the retaining frame 6, the placement frame 10 is positioned and fixed, completing the assembly. During operation, the sealing plate 5 is placed into the connecting sealing groove 8 to seal the guide groove 7, ensuring aesthetics during use. During use, the dustproof net 12 and activated carbon plate 11 can prevent mosquitoes and other insects from entering the room through the entrance door. When disassembly, cleaning, or replacement is required, the sealing plate 5 can be removed, and then the positioning block 16 can be pressed into the actuating groove 17 to move the positioning block 16 out of the positioning hole 9, thereby losing its limiting and fixing effect on the placement frame 10. It can then be removed, and then the connecting plate 4 can be removed by using the mounting slider 14 and mounting groove 15, making it convenient for cleaning or replacement.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
