The fixing member 2 and the seal 22 are screwed through the through hole 20 and the seal installation hole 221 in sequence and the fixing member 2 and the seal 22 are installed on the door frame. Such a structural design makes the sealing effect of the sealing mechanism better.

[0024] As described above, the fixing member includes a horizontal plate 23, a first vertical plate 24 and a second vertical plate 25 extending from the horizontal plate 23 to a direction perpendicular to the horizontal plate 23, a first clamping block 241 extending outward is provided at the end of the first vertical plate 24 away from the horizontal plate 23, and a second clamping block 251 extending outward is provided at the end of the second vertical plate 25 away from the horizontal plate 23, and the first clamping block 241 and the second clamping block 251 are simultaneously engaged with the first shielding plate 26 located at the front side of the fixing member 2. Specifically, the first shielding plate 26 is provided with a clamping groove 261 that can be engaged with the first clamping block 241 and the second clamping block 251. The structural design of the first shielding plate 26 can shield the adjusting bolt 31 and the sealing strip connector 32, making the overall appearance of the sealing strip more beautiful.

[0025] As described above, the first vertical plate 24 is provided with a first mounting hole 242, the second vertical plate 25 is provided with a second mounting hole 252, and the adjusting bolt 31 is sequentially passed through the first mounting hole 242 and the second mounting hole 252 from one side of the first vertical plate 24 and is screwed with the screw connection portion 33.
