[0041] In this embodiment: a plurality of airtight tubes 32 are evenly arranged on both sides of the sound insulation board 31 , and a plurality of airtight tubes 32 are respectively fitted and embedded in the interior of the sound insulation board 31 , and the interior of the protective cover 14 is fitted and arranged to fit the designated inner wall of the protective cover 14 .

[0042] The protective cover 14 and the sound insulation board 31 are used to adapt to the installation of the airtight pipe 32 to improve the embedded protection of the purified airtight steel door after it is penetrated.

[0043] In this embodiment: a linear pushing mechanism 2 is provided on the top of the protective cover 14;

[0044] The linear pushing mechanism 2 includes concave pushing brackets 21 respectively installed on the top of the protective cover 14 , and rack rails 22 are symmetrically installed on both side walls of the concave pushing brackets 21 .
