[0038] The central angle of the sleeve washer limiting groove 4.21 is a right angle.

[0039] The outer frame mechanism 2 includes an outer frame outer plate 2.1, an outer frame inner plate 2.2, a first connecting plate 2.3, a wedge strip 2.4, a contact rod 2.5, a limiting block 2.6, a second connecting plate 2.7, and a hinge seat plate 2.8;

[0040] The outer end of the first connecting plate 2.3 is fixed to the inner side of the outer frame outer plate 2.1, and the inner end of the first connecting plate 2.3 is fixed to the outer side of the outer frame inner plate 2.2.

[0042] The diameter of the contact rod 2.5 is larger than the width of the inner cladding plate 2.2 of the outer frame. This improves the contact bonding between the contact rod 2.5 and the fireproof and watertight adhesive strip 1.4, thereby enhancing the fireproof and water-tight properties.

[0043] The height of the outer frame outer panel 2.1 is greater than the height of the outer frame inner panel 2.2.

When the tie head 4.4 rotates to be parallel to the wedge 2.4, the cover plate mechanism 1 and the outer frame mechanism 2 are separated, and the cover plate mechanism 1 can rotate freely.

[0047] After the cover plate mechanism 1 of this utility model is tightened, the fireproof and watertight adhesive strip 1.4 presses against the contact rod 2.5, thus providing fireproofing and water resistance. The fireproof expanding film 1.5 expands when exposed to fire, filling the space enclosed by the inner side panel 1.3 of the cover plate, the inner side panel 2.2 of the outer frame, and the wedge strip 2.4, greatly improving the fire resistance of this utility model. The limiting block 2.6 cooperates with the outer side panel 1.2 of the cover plate to prevent overpressure on the fireproof and watertight adhesive strip 1.4, protecting the fireproof and watertight adhesive strip 1.4 and extending its service life.

[0048] This utility model's fire-resistant watertight hatch cover boasts a watertight performance up to 5 meters underwater, A0-level fire resistance, 38dB sound insulation, and a U-value of 1.0W / ㎡℃, meeting the needs of various environments. It significantly improves safety, comfort, and product durability.
