[0029] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0030] Example 1:

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model is a three-layer sealing structure entrance door, including a door leaf 1 and a door frame 3. The door leaf 1 is rotatably connected to the door frame 3 by a hinge 2. The door leaf 1 and the door frame 3 are provided with a mounting groove 4 on one side of the opposite sides. The mounting groove 4 is internally provided with a mounting block 5. A fixing groove 13 is provided on one side of the mounting block 5. A connecting block 6 is internally provided with a fixing groove 13. The opposite sides of the two connecting blocks 6 are respectively provided with a first sealing strip 7 and a second sealing strip 8. The entrance door of this three-layer sealing structure significantly improves the sealing effect through the door leaf 1, the door frame 3 and the multiple sealing design. During the installation process, the first sealing strip 7 on the door frame 3 and the second sealing strip 8 on the door leaf 1 are connected. The seals 8 abut against each other when the door leaf is rotated and closed by the hinge 2, forming an effective first sealing layer. At the same time, the third sealing strip 9 on the side of the door leaf 1 is fixed by the mounting frame 10 and the block 11, and is squeezed when the door leaf 1 is closed, forming a second seal. Finally, the fourth sealing strip 16 at the bottom of the door leaf 1 is in close contact with the door frame 3 under the action of the placement groove 14 and the placement block 15, realizing the third seal, improving the sealing effect, ensuring the dryness of the room, strictly preventing the intrusion of moisture and rainwater, avoiding the possible undesirable effects of a single-layer sealing material, greatly improving the sealing and sound insulation effects of the entrance door, and providing a quieter and more comfortable environment for the home.

[0032] like Figure 1 、 Figure 2 、 Figure 3 As shown, the front side of the mounting block 5 is provided with an "L"-shaped hook, and the two sides of the connecting block 6 are inclined structures for providing a snap-fit fixation for the mounting block 5 and the connecting block 6. The "L"-shaped hook can enhance the stability between the mounting block 5 and the mounting groove, ensuring that the sealing structure is not easy to loosen or fall off after installation, making the installation process simpler and firmer, and improving the installation efficiency and reliability of use. At the same time, the inclined structure design on both sides of the connecting block 6 is convenient for snapping and fixing with the mounting block 5. The inclined structure can play a guiding role in the installation process, making it easier for the connecting block 6 to snap into place with the mounting block, which not only simplifies the installation steps, but also ensures the accuracy and stability of the installation position of the sealing strip, thereby further improving the sealing effect of the entrance door.

[0033] like Figure 1 、 Figure 2As shown, a placement groove 14 is provided on one side of the bottom of the door leaf 1, and a placement block 15 is provided inside the placement groove 14. A fourth sealing strip 16 is provided at the bottom of the placement block 15, which provides a convenient and stable fixing method for installing the fourth sealing strip 16. Through the engagement of the placement groove 14 with the placement block 15, it can be ensured that the fourth sealing strip 16 is firmly installed at the bottom of the door leaf 1 and is not easy to fall off or shift. At the same time, the fourth sealing strip 16 can fit tightly with the door frame 3 when the door leaf 1 is closed to form an effective sealing layer, which not only enhances the sealing performance of the entrance door and prevents the penetration of air, moisture and noise, but also improves the overall sound insulation and heat preservation effect of the door, providing a more comfortable and quiet living environment for the residents.

[0034] like Figure 1 、 Figure 2 、 Figure 4 As shown, a mounting frame 10 is provided on one side of the door leaf 1 close to the door frame 3, and a card block 11 is provided on one side of the mounting frame 10 through a card slot 12. A third sealing strip 9 is provided on the top of the card block 11, which provides a solid foundation for the installation of the third sealing strip 9. The mounting frame 10 enhances the structural strength of the door leaf, making the installation of the sealing strip more firm and reliable. At the same time, the card slot 12 on one side of the mounting frame 10 and the card block 11 are engaged, which simplifies the installation process of the third sealing strip 9 and improves the installation efficiency. This engaging method can ensure that the third sealing strip 9 fits tightly on the door leaf 1. When the door leaf is closed, the third sealing strip 9 can be effectively squeezed to form a tight sealing layer, further improving the sealing performance and sound insulation effect of the entrance door.

[0035] Example 2:

[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the materials of the first sealing strip 7, the second sealing strip 8, the third sealing strip 9 and the fourth sealing strip 16 are all EPDM, and the EPDM is provided with three layers. The EPDMs are bonded together by EPDM foam sealing strips, which can ensure that the sealing strips have good elasticity, aging resistance and corrosion resistance, thereby extending the service life of the sealing strips and improving the sealing effect of the entrance door. At the same time, the EPDM is provided with three layers and bonded together by EPDM foam sealing strips, which further enhances the sealing performance and structural stability of the sealing strips, so that the sealing strips can better fill the gaps when squeezed, and prevent the penetration of air, moisture and noise, thereby providing a quieter, drier and more comfortable living environment.

[0037] like Figure 1 、 Figure 2 、 Figure 3As shown, the first sealing strip 7 and the second sealing strip 8 are in contact with each other, and reinforcement strips are provided on the inner sides of the first sealing strip 7 and the second sealing strip 8. When the door leaf 1 is closed, a tight sealing layer can be formed to effectively prevent air, moisture, noise, etc. from penetrating from the door gap, thereby improving the sealing and sound insulation effect of the entrance door. At the same time, the reinforcement strips provided on the inner sides of the first sealing strip 7 and the second sealing strip 8 can enhance the structural strength and stability of the sealing strips. The reinforcement strips can prevent the sealing strips from being deformed or damaged during long-term use, thereby ensuring that the sealing strips always maintain a good sealing effect, further extending the service life of the sealing strips, and improving the overall quality and durability of the entrance door.

[0038] like Figure 1 、 Figure 2 、 Figure 4 As shown, a slope is provided on one side of the third sealing strip 9, and the slope is in contact with the door leaf 1; a slope is provided on one side of the fourth sealing strip 16, and the slope is in contact with the door frame 3, so that the door leaf 1 can fit more closely with the third sealing strip 9 when closed, thereby enhancing the sealing effect. The slope structure helps to guide the door leaf 1 to close correctly, reduce the gap, and prevent the infiltration of air and noise. At the same time, a slope is also provided on one side of the fourth sealing strip 16, and it is in contact with the door frame 3, ensuring a close fit between the door frame 3 and the door leaf 1, further improving the overall sealing of the entrance door. The slope not only simplifies the installation process, but also enables the sealing strip to fill the gap more effectively when squeezed, thereby improving the sound insulation and heat preservation effects.

[0039] After the first sealing strip 7 is installed on the door frame 3, the second sealing strip 8 is installed on the door leaf 1. When the door leaf 1 is rotated by the hinge 2 and closed with the door frame 3, the first sealing strip 7 and the second sealing strip 8 abut each other, and the first sealing strip 8 is sealed for the entrance door. Then the card block 11 is inserted into the card slot 12 to complete the installation of the third sealing strip 9. The third sealing strip 9 is installed on the door frame 3. When the door leaf 1 is closed, the door leaf 1 squeezes the third sealing strip 9, so that the third sealing strip 9 performs a second sealing for the entrance door. Finally, the placement block 15 is inserted into the placement slot 14 to complete the installation of the fourth sealing strip 16. The fourth sealing strip 16 is set on the door frame 3. When the door leaf 1 rotates, the third sealing is performed on the entrance door. During this installation process, the three layers of the entrance door are sealed respectively, thereby improving its sealing effect and thereby enhancing the sound insulation effect of the entrance door.

[0040] The first sealing strip 7, the second sealing strip 8, the third sealing strip 9 and the fourth sealing strip 16 are all made of three-layer EPDM sealing materials. The three-layer sealing material has a strong sealing effect and ensures indoor dryness, strictly isolates the air and moisture inside and outside the door, effectively prevents the intrusion of moisture and rainwater, and avoids the use of a single-layer sealing material that cannot achieve the ideal sealing effect, thereby improving the sealing effect of the entrance door.

[0041] The advantages of this technical solution in practical applications include but are not limited to the following:

[0042] 1. Improve its sealing effect, thereby enhancing the sound insulation effect of the entrance door;

[0043] 2. Strictly isolate the air and moisture inside and outside the door, effectively preventing the intrusion of moisture and rainwater.
