[0006] Further, the outer peripheral wall of the box shell forms a groove accommodating the screw rod, and the number of the screw rods is two, which are symmetrically distributed on both sides of the box shell.

[0007] Further, one end of the sliding fixing block is provided with a threaded hole for the screw rod to enter, and the other end of the sliding fixing block forms a bent part to fit the ship bulkhead.

[0008] Further, the bottom of the box shell is provided with a fixed heat sink, the fixed heat sink is cross-distributed on the bottom of the box shell, and is upwardly folded to fit the outer wall of the box shell.

[0009] Further, the bottom of the cassette shell is provided with a positioning slot, the positioning slot is four circular arc segments equally spaced along the circumference, and the four circular arc segments form a limiting cross for fixing the heat dissipation fin to pass through.

[0010] The utility model discloses the following beneficial effects compared with the prior art: the marine electrical wiring cassette provided by the utility model rotates the screw rod through the threaded rotating tool, and the sliding fixing block is installed and fixed along the axial movement of the screw thread of the screw rod, which does not damage the ship cabin wall structure, the screw rod design does not need to reserve the installation screw hole distance of the ship cabin wall opening, the internal cavity can be designed larger, and it is more favorable for the installation of marine electrical switches, lamps and other electrical equipment. In addition, the positioning slot designed in the cassette shell can be positioned and attached first, and then attached along the side wall of the cassette shell, which is convenient, simple and time-saving, avoids multiple operations and rework, and can effectively save manpower and material resources.
