[0025] Embodiment 1

[0026] Please refer to Figure 1 , a flexible magnetic sealing body, including a first sealing body 2 and a second sealing body 3. The first sealing body 2 and the second sealing body 3 are arranged on the component to be sealed 1. The first sealing body 2 and the second sealing body 3 are flexible magnetic strips, and the opposite sides of the first sealing body 2 and the second sealing body 3 have opposite magnetic poles. A third sealing body 4 is arranged on the component to be sealed 1, and the third sealing body 4 is located below the first sealing body 2 and the second sealing body 3.

[0027] Working principle and beneficial effects of the above solution:

[0028] In this application, first, the first sealing body 2 and the second sealing body 3 are adsorbed to each other through the magnetic force between them. Then, the part of the component to be sealed 1 where the adsorbed first sealing body 2 and the second sealing body 3 are located is folded, so that one of the first sealing body 2 and the second sealing body 3 contacts the third sealing body 4 arranged on the component to be sealed 1, and the third sealing body 4 is adsorbed and sealed with one of the first sealing body 2 and the second sealing body 3. While ensuring the sealing effect, the use of the sealing body is reduced, and the cost is saved.

[0029] Embodiment 2

[0030] Please refer to Figure 1 , on the basis of Embodiment 1, the third seal 4 is located on the side of the piece to be sealed 1 where the first seal 2 is provided, and the magnetic pole direction of the third seal 4 is opposite to that of the second seal 3.

[0031] The third seal 4 is located on the side of the piece to be sealed 1 where the second seal 3 is provided, and the magnetic pole direction of the third seal 4 is opposite to that of the first seal 2.

[0032] The first seal 2, the second seal 3, and the third seal 4 are a combination of a flexible material and a magnetic material, and the flexible material and the magnetic material of the first seal 2, the second seal 3, and the third seal 4 are integrally formed.

[0033] The working principle and beneficial effects of the above solution:

[0034] By setting the magnetic pole direction of the third seal 4 to be opposite to that of the seal on the opposite side, after folding the piece to be sealed 1, when the third seal 4 adsorbs to the seal on the opposite side (the first seal 2 or the second seal 3), the piece to be sealed 1 is sandwiched between them, performing secondary sealing on the piece to be sealed 1 and ensuring the sealing effect of the piece to be sealed 1;

[0035] The first seal 2, the second seal 3, and the third seal 4 with the flexible material and the magnetic material integrally formed have the advantage of low cost compared with the existing method of embedding several tiny magnetic particles in a flexible material such as silica gel, and there will be no situations such as the magnetic particles slipping out, falling off, rusting, and corroding after the silica gel strip ages.

[0036] Embodiment 3

[0037] Please refer to Figures 2-3 , on the basis of Embodiments 1 - 2, an auxiliary sealing component is provided on the piece to be sealed 1, and the auxiliary sealing component is located above the first seal 2 and the second seal 3.

[0038] The auxiliary sealing component includes a first fixing strip 5, the first fixing strip 5 is arranged inside the piece to be sealed 1, and the first fixing strip 5 is located above the first seal 2, and two symmetrically arranged inserting strips 10 are fixedly connected to the first fixing strip 5.

[0039] An elastic body 11 is arranged between the two inserting strips 10, and both sides of the elastic body 11 are fixedly connected to the middle positions of the two inserting strips 10 respectively.

[0040] The auxiliary sealing assembly includes a second fixing strip 6 which is arranged inside the piece to be sealed 1 and above the second sealing body 3. A cavity 7 is arranged inside the second fixing strip 6. An opening 9 is arranged on the side of the second fixing strip 6 facing the first fixing strip 5, and the opening 9 communicates with the cavity 7. A sealing column 8 is arranged inside the cavity 7.

[0041] When the first fixing strip 5 and the second fixing strip 6 approach each other, the two sets of insertion strips 10 are respectively located on both sides of the sealing column 8.

[0042] When the first fixing strip 5 and the second fixing strip 6 approach each other, the insertion strip 10 is inserted between the sealing column 8 and the second fixing strip 6.

[0043] The working principle and beneficial effects of the above solution:

[0044] While the first sealing body 2 and the second sealing body 3 adsorb and seal, the insertion strips 10 are respectively placed on both sides of the sealing column 8, and the insertion strip 10 is inserted between the sealing column 8 and the second fixing strip 6. The insertion strip 10 abuts against the sealing column 8 and the second fixing strip 6, further enhancing the sealing effect of the piece to be sealed 1.
