DETAILED DESCRIPTION

[0024] In order to make the above features and advantages of the utility model more obvious and easy to understand, the following specific examples are given, and the detailed description is as follows in cooperation with the drawings.

[0025] Embodiment 1

[0026] As Figures 1-3 Indicated, the embodiment provides a kind of inflatable sealing strip at the door of sterilization box, including box body 1, annular inflatable sealing ring 2 and connecting component 3.

[0027] Box body 1 material is magnetic metal, the opening of box body 1 is formed with the continuous closed loop sealing gap 11 outwardly opened, through hole 16 is formed on the side wall of sealing gap 11, sealing gap 11 includes first plane 12 and second plane 13, a plurality of limiting grooves 14 are formed on first plane 12 and second plane 13, the number of limiting groove 14 on each plane in the embodiment is 2, limiting groove 14 on first plane 12 and second plane 13 is staggered.

[0028] The material of annular inflatable sealing ring 2 is silicone rubber, styrene-butadiene rubber, ethylene-propylene-diene rubber, fluorine rubber or hydrogenated nitrile rubber. Annular inflatable sealing ring 2 vertical section is L type, annular inflatable sealing ring 2 is laid in sealing gap 11, annular inflatable sealing ring is connected in sealing gap 11 by connecting component 3, air inlet is provided on annular inflatable sealing ring 2, air inlet is provided with air inlet 23, air inlet 23 is stretched out from through hole 16. Annular inflatable sealing ring 2 has first matching surface 24 corresponding to first plane 12 and second matching surface 25 corresponding to second plane 13,

[0029] The connecting component 3 includes a magnetic block 31, which is mounted on the first mating surface 24 and the second mating surface 25. A limiting groove 14 is formed on the first plane 12 and the second plane 13, and the magnetic block 31 is adapted to the limiting groove 14. Specifically, there are two magnetic blocks 31 on each mating surface, and the magnetic blocks 31 are connected to the mating surface by adhesive.

[0030] Example 2

[0031] like Figures 4-8 As shown, the difference between this embodiment and Embodiment 1 is that the first mating surface 24 has six spaced through holes 21, and a pressure ring 22 is provided on the inner circumferential surface of the through holes 21. The first plane 12 has threaded holes 15 corresponding to the through holes 21. The second mating surface 25 has seven through holes 21, and the through holes 21 of the second mating surface 25 have the same structure as the through holes 21 of the first mating surface 24. The second plane 13 has threaded holes 15 corresponding to the through holes 21 of the second mating surface 25.

[0032] The connecting component 3 includes fifty-two connectors 32. Each connector 32 includes a head 321 and an extension 322. The extension 322 has an external thread on its circumferential surface. The extension 322 of the connector 32 is adapted to the threaded hole 15 and the head 321 presses against the pressure ring 22.

[0033] Preferably, the head 321 of the connector 32 may be fitted with a chamfered plastic protective sleeve to prevent the annular inflatable sealing ring 2 from being punctured by the head 321 when it is inflated.

[0034] In both embodiments of this solution, an annular inflatable sealing ring 2 is installed in the sealing notch 11 at the opening of the box body 1. The annular inflatable sealing ring 2 is fixed at the sealing notch 11 by the connecting component 3 (magnetic block 31 or connector 32) to ensure that the annular inflatable sealing ring 2 will not shift. After the door of the sterilization box closes the sealing notch 11, the annular inflatable sealing ring 2 is inflated. The annular inflatable sealing ring 2 expands and seals the gap between the box body 1 and the door, ensuring that the seal is in place. Since the annular inflatable sealing ring 2 is relatively large, the connecting component 3 is provided to ensure that the annular inflatable sealing ring 2 is firmly connected to the sealing notch 11.
