Description

Technical Field

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

[0002] An entrance door is the door in a building such as a home, apartment, or residence that connects the exterior and interior. Aluminum alloy materials are widely used in building doors and windows due to their advantages such as light weight, easy installation, reusability, and environmental friendliness. Because thermally broken aluminum alloy doors offer excellent heat insulation and soundproofing, and their thermal break strips ensure that the exterior door panel maintains a similar temperature to the outside, and the interior door panel maintains a similar temperature to the interior, they are less prone to condensation and can extend the door's lifespan. Therefore, they are increasingly used in entrance doors.

[0003] Existing thermal break doors typically consist of a door leaf, a door frame, and hinges. The hinges are fixedly installed in mounting holes on the door frame, and the door leaf is then hinged to the door frame via the hinges. After the hinges are installed, the mounting holes are exposed without any protective treatment. This not only reduces the neatness and aesthetics of the entrance door but also makes it easy for dust and impurities to enter the hinges, leading to accelerated wear and tear and reducing the lifespan of the hinges and even the entire thermal break door.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, one embodiment of this utility model provides an entrance door, which includes a first door leaf 1, a first hinge 2, and a main door frame 3. The main door frame 3 has a first mounting hole, and the first hinge 2 is fixedly mounted on the main door frame 3 through the first mounting hole. The first door leaf 1 is hinged to the main door frame 3 through the first hinge 2. Specifically, one end of the hinge can be mounted to the main door frame 3 using a screw that matches the first mounting hole, and then the other end of the hinge can be fixed to the first door leaf 1 using a screw or bolt, thereby achieving the hinge between the first door leaf 1 and the main door frame 3. A material layer 23 is filled inside the first door leaf 1. This material includes, but is not limited to, polyurethane foam, rock wool, and expanded glass, which has sound insulation, heat insulation, and fireproofing effects. Figure 1 For along Figure 6 A schematic diagram of the cross-sectional structure of the CD line.

[0033] The entrance door also includes a first frame decorative cover 4 and a first door leaf frame 5. The first frame decorative cover 4 is fixedly installed on the main door frame 3 and is used to cover the first mounting hole. The first door leaf 1 is fixedly installed on the first door leaf frame 5. The first door leaf frame 5 is hinged to the main door frame 3 through the first hinge 2. A first multi-cavity heat insulation strip 6 is fixedly installed on the main door frame 3. A first equal pressure rubber strip 7 is fixedly installed on the first door leaf frame 5. The first multi-cavity heat insulation strip 6 overlaps with the first equal pressure rubber strip 7.

[0034] Preferably, the overlap here is a surface overlap to increase the contact area between the first multi-cavity thermal insulation strip 6 and the first equal-pressure adhesive strip 7, thereby improving the thermal and sound insulation performance of the entrance door. For example... Figure 1 As shown, the first multi-cavity heat insulation strip 6 can be fixedly installed on the main door frame 3 by snap-fit, and the first equal pressure adhesive strip 7 can be fixedly installed on the first door leaf frame 5 by snap-fit. Similarly, the hole cover is fixedly installed on the main door frame 3 by snap-fit.

[0035] The entrance door, by providing a first frame decorative cover 4 to cover the first mounting hole, not only improves the door's neatness and aesthetics but also prevents dust and impurities from entering the mounting hole and hinges, reducing hinge wear during use and extending the lifespan of both the hinges and the entrance door. Furthermore, the overlap between the first multi-cavity thermal insulation strip 6 and the first equal-pressure adhesive strip 7 in the entrance door effectively ensures its thermal insulation and sound insulation performance, making it highly practical overall.

[0036] As a preferred technical solution, such as Figure 1 As shown, the entrance door also includes a first sealing strip 8, the main door frame 3 includes a first main frame body 30, the first door leaf frame 5 includes a first door leaf main material 50, the first door leaf main material 50 is provided with a first mounting groove 51, the first sealing strip 8 is fixedly installed in the first mounting groove 51, the first multi-cavity heat insulation strip 6 is provided with a first snap-fit ​​groove 60 on the side near the first main frame body 30, the first frame decorative cover 4 includes a first snap-fit ​​part 40 and a first extension part 41, the first snap-fit ​​part 40 snaps into the first snap-fit ​​groove 60, and the first extension part 41 abuts against the first sealing strip 8.

[0037] Here, the first frame decorative cover 4 can extend along the length of the corresponding main door frame 3, covering the entire side of the main door frame 3. The first sealing strip 8 mainly functions as dustproof and soundproof. The first snap-fit ​​part 40 snaps into the first snap-fit ​​groove 60 and the first extension part 41 abuts against the first sealing strip 8. This serves two purposes: firstly, to improve the firmness of the installation of the first frame decorative cover 4 and prevent it from falling off due to vibration; and secondly, to improve the overall aesthetics of the entrance door. In addition, the abutment between the first extension part 41 and the first sealing strip 8 can also, to a certain extent, ensure the sealing performance between the main door frame 3 and the first door leaf frame 5, thereby improving the sound and heat insulation performance of the entrance door.

[0038] As a preferred technical solution, such as Figure 6 , Figure 7 , Figure 8 as well as Figure 9 As shown, the entrance door also includes a threshold 9, the lower end of the main door frame 3 is connected to one end of the threshold 9, and the lower end of the first door leaf frame 5 is connected to the other end of the threshold 9.

[0039] Specifically, the threshold 9 includes a first threshold profile 90, a second threshold profile 91, and a threshold heat insulation strip 92. The first threshold profile 90 and the second threshold profile 91 are fixedly connected by the threshold heat insulation strip 92. The first threshold profile 90 is provided with a water-blocking step 900 and a drainage slope 901. The main functions of the threshold 9 are as follows:

[0040] 1. It prevents outdoor wind, rain, dust, dirt and other impurities from entering the room, keeping the indoor environment clean.

[0041] 2. The threshold 9, as the transition part between the door frame and the ground, can withstand a certain amount of friction and impact, thereby protecting the ground from damage caused by the opening or closing of the door. At the same time, it makes the door fit the ground more stably, reduces door shaking, and improves service life.

[0042] 3. The tight fit between the threshold 9 and the door frame and the ground improves the door's heat insulation and sound insulation, thereby enhancing the comfort of the home environment.

[0043] The installation of the water-blocking step 900 and the drainage slope 901 can further prevent rainwater from entering the room and reduce air and rain leakage through the door gaps.

[0044] like Figure 10As shown, the entrance door also includes a stop strip 10 and a second sealing strip 12. A second pressure-equalizing strip 11 is fixedly installed at the lower end of the first door frame 5. The stop strip 10 is snapped onto the second threshold profile 91. The stop strip 10 abuts against the second pressure-equalizing strip 11. The lower end of the first door frame 5 is connected to the threshold 9 through the second pressure-equalizing strip 11 and the stop strip 10.

[0045] The entrance door also includes a second sealing strip 12. The lower end of the first door frame 5 is provided with a second mounting groove 52. The second sealing strip 12 is fixedly installed in the second mounting groove 52. The second sealing strip 12 abuts against the end of the first threshold profile 90 on the surface of the second mounting groove 52.

[0046] The abutting strip 10 and the second equal pressure strip 11 are tightly abutted and adhered, and the second sealing strip 12 is tightly adhered to the surface of the water-blocking step 900, which can ensure the sealing performance of the entrance door and improve its sound insulation and heat insulation effect.

[0047] As a preferred technical solution, such as Figure 1 as well as Figure 3 As shown, the entrance door also includes a second door leaf 16, a second hinge 17, and a second frame decorative cover 18. The main door frame 3 is provided with a second mounting hole. The second hinge 17 is installed in the second mounting hole. The second door leaf 16 is hinged to the main door frame 3 through the second hinge 17. The second frame decorative cover 18 is fixedly installed on the main door frame 3 and is used to cover the second mounting hole.

[0048] The entrance door also includes a second door frame 19, with the second door leaf 16 fixedly mounted on the second door frame 19. The second door frame 19 is hinged to the main door frame 3 via the second hinge 17. A second multi-cavity heat insulation strip 20 is fixedly mounted on the main door frame 3, and a third pressure-equalizing rubber strip 21 is fixedly mounted on the second door frame 19. The second multi-cavity heat insulation strip 20 overlaps with the third pressure-equalizing rubber strip 21. Preferably, this overlap is a surface overlap, which increases the contact area between the second multi-cavity heat insulation strip 20 and the third pressure-equalizing rubber strip 21, thereby improving the sound and heat insulation performance of the entrance door.

[0049] The second frame decorative cover 18 can extend along the length of the corresponding main door frame 3, covering the side of the main door frame 3, improving the overall aesthetics of the entrance door while ensuring its sound and heat insulation effect.

[0050] like Figure 3 as well as Figure 5As shown, the entrance door also includes a fourth sealing strip 22. The second door frame 19 includes a second door main material 190. The second door main material 190 is provided with a fourth mounting groove 191. The fourth sealing strip 22 is fixedly installed in the fourth mounting groove 191. The second multi-cavity heat insulation strip 20 is provided with a second snap-fit ​​groove 200 on the side near the first main frame 30. The second frame decorative cover 18 includes a second snap-fit ​​part 180 and a second extension part 181. The second snap-fit ​​part 180 snaps into the second snap-fit ​​groove 200, and the second extension part 181 abuts against the fourth sealing strip 22.

[0051] The second snap-fit ​​portion 180 snaps into the second snap-fit ​​groove 200, and the second extension portion 181 abuts against the second sealing strip 12. Its functions include: 1. ensuring the connection between the second frame decorative cover 18 and the second multi-cavity heat insulation strip 20 by snap-fitting, and preventing the second frame decorative cover 18 from shaking or falling off; 2. the second frame decorative cover 18 is generally made of plastic with good insulation properties, and its snap-fitting with the second multi-cavity heat insulation strip 20 can also enhance the sound insulation and heat insulation effect of the entrance door to a certain extent.

[0052] As a preferred technical solution, such as Figure 10 As shown, the entrance door also includes a connector 14 and a third sealing strip 15. The connector 14 is fixedly installed at the lower end of the first door frame 5. The bottom of the connector 14 is provided with a third mounting groove 140. The third sealing strip 15 is fixedly installed in the third mounting groove 140, and the end of the third sealing strip 15 away from the first door frame 5 abuts against the ground. The entrance door of this utility model includes two technical solutions for lower thresholds: one is a low threshold, achieved through the structure of the threshold 9; the other is a thresholdless design, achieved through the connector 14 and the third sealing strip 15 to achieve a sealing state between the first door frame 5 and the ground. In this embodiment, the entrance door does not have a threshold, such as... Figure 8 As shown, the third sealing strip 15 and the connector 14 ensure the sealing effect of the door gap between the first door frame 5 and the ground, thereby simplifying the overall structure of the entrance door.

[0053] Of course, depending on the customer's needs, the entrance door may also be without a threshold structure and a third sealing strip 15. In this case, the entrance door is in a non-sealed state without a threshold 9.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
