[0024] Please see Figure 1-4 ,

[0025] Example 1: A silent safety door with a flush frame and door panel includes a door frame 1. A reserved groove 2 is provided on the side of the door frame 1. An embedded groove 3 is provided on the inner wall of the reserved groove 2. A sealing strip 4 is bonded in the embedded groove 3. A door panel 5 is provided inside the door frame 1. Three hinge mounting grooves 6 are evenly provided on the side wall of the reserved groove 2. A connecting hinge 7 is provided in each of the hinge mounting grooves 6. The door frame 1 and the door panel 5 are rotatably connected by the connecting hinges 7. A silent sealing component 8 is also provided at the bottom of the door frame 1.

[0026] The silent sealing assembly 8 includes sealing connecting plates 801 symmetrically arranged at the bottom of the side of the door frame 1. Each end of the sealing connecting plate 801 is provided with a first magnet block 802. A bottom side slot 803 is formed at the bottom of the sealing connecting plate 801, and a rubber sealing plate 804 is inserted into the bottom side slot 803. Three abutment rods 805 are evenly inserted into the top of the sealing connecting plate 801. The bottom end of each abutment rod 805 is fixedly connected to the top end of the rubber sealing plate 804. Each abutment rod 805 is fitted with an abutment spring 806. One end of the spring 806 is connected to the body of the abutting rod 805, and the other end of the abutting spring 806 is connected to the top of the sealing connecting plate 801. The end of the sealing connecting plate 801 is provided with a rotating insertion hole 807. Two rotating rods 808 are symmetrically arranged at the bottom of the side of the door frame 1. The end of the rotating rod 808 passes through the rotating insertion hole 807. A rotating baffle 809 is provided at the end of the rotating rod 808. Two magnet mounting slots 810 are symmetrically opened on the side of the door frame 1. A second magnet block 811 is provided in each of the magnet mounting slots 810.

[0027] Example 2: The difference between this example and Example 1 is that the length of the two sealing connecting plates 801 is equal to the length of the door panel 5.

[0028] After the two sealing connecting plates 801 rotate, the ends of the two sealing connecting plates 801 can be magnetically fixed by the first magnet block 802, completely closing the bottom of the door panel 5.

[0029] Example 3: The difference between this example and Example 1 is that a baffle is provided at the top of the abutting rod 805.

[0030] This causes the top of the abutment spring 806 on the abutment rod 805 to be abutted and limited.

[0031] Example 4: The difference between this example and Example 1 is that the height of the second magnet block 811 from the bottom of the door frame 1 is the same as the height of the sealing connection plate 801.

[0032] When the sealing connection plate 801 rotates on the side of the door frame 1, the first magnet block 802 at the end of the sealing connection plate 801 can be transferred to the side of the second magnet block 811, so that the first magnet block 802 and the second magnet block 811 are magnetically attracted and fixed.

[0033] In this embodiment, since most existing security doors are made of high-strength steel plates, their strength has been greatly improved. However, traditional doors have large gaps between the frame and the leaf, resulting in insufficient sealing and difficulty in effectively blocking external noise. This makes the user's living and working space very noisy, seriously interfering with the rest, work, study and communication of people indoors, greatly reducing the comfort of life and work, and failing to meet the user's needs.

[0034] In summary, in specific implementation, by opening a reserved groove 2 on the side of the door frame 1, and an embedded groove 3 in the reserved groove 2, and a sealing strip 4 is bonded in the embedded groove 3, the gap between the door panel 5 and the inner wall of the door frame 1 can be filled after the door panel 5 is rotated into the reserved groove 2, thereby improving the sealing between the door panel 5 and the door frame 1 and blocking the noise from outside.

[0035] A silent sealing assembly 8 is provided at the bottom of the side of the door frame 1. Since there is a gap between the bottom of the door frame 1 and the ground, and a gap between the bottom of the door panel 5 and the ground, when the user rotates the door panel 5 to close the door frame 1, the user can rotate the sealing connecting plate 801 in the silent sealing assembly 8 so that the ends of the two sealing connecting plates 801 fit together. Each end of the sealing connecting plate 801 is provided with a first magnet block 802, which can fix the two sealing connecting plates 801 together under the magnetic attraction of the first magnet block 802. Each bottom of the sealing connecting plate 801 is provided with a rubber sealing plate 804. The top of the rubber sealing plate 804 is connected to the abutment rod 805, and an abutment spring 806 is sleeved on the abutment rod 805.

[0036] The rebound force of the contact spring 806 can tighten the contact rod 805, causing the contact rod 805 to push the rubber sealing plate 804, thereby making the rubber sealing plate 804 fit against the ground, thus sealing the gaps between the door frame 1 and the door panel 5 and the ground. In conjunction with the sealing strip 4, it can completely seal the gaps between the door panel 5 and the door frame 1 and between the door and the ground, more effectively blocking outdoor noise, improving indoor quietness, and making it more conducive to the rest, work, study and communication of people indoors, greatly improving people's living and working comfort and meeting the user's needs.
