The outer layer plate 2 and the inner layer plate 1 are detachably connected by multiple bolts 5, and a first slide groove 14 is provided on the outer side of the inner layer plate 1, and a second slide groove 16 corresponding to the first slide groove 14 is provided on the inner side of the outer layer plate 2. The first slide groove 14 and the second slide groove 16 are combined to form a long groove, and a first oblong hole 8 is provided on the inner and outer sides of the long groove, and a slide plate 6 is slidingly provided in the long groove. A sealing tube 7 is vertically penetrated on the slide plate 6, and the sealing tube 7 is configured to be able to move in the first oblong hole 8. A plurality of O-rings 10 are embedded in the middle of the sealing tube 7.

[0030] Through the implementation of the above technical solution, when in use, the side of the inner plate 1 with the positioning boss 11 is facing the equipment window, and the positioning boss 11 is positioned by cooperating with the positioning groove corresponding to the equipment window. Then, the countersunk screw 12 is passed through the countersunk groove and the positioning boss 11 and screwed to the installation position of the equipment window, so that the inner plate 1 is fixed. Then, the slide plate 6 and the outer plate 2 are installed in sequence. During installation, the slide plate 6 needs to be sleeved with the corresponding wire harness or tube bundle led out of the equipment. The wire harness or tube bundle is in sealing contact with multiple O-rings 10. When installing the outer plate 2, it is screwed to the inner plate 1 through multiple bolts 5 to fix them together. After installation, the sealing tube 7 can move within the range of the first oblong hole 8. According to the installation posture of the inner plate 1, the sealing tube 7 can move horizontally, vertically, or diagonally. At the same time, the slide plate 6 can move back and forth in the long groove, following the movement of the sealing tube 7.
