[0002] A cover device for molten iron mixing cars is used to cover the molten iron during transportation, which can significantly reduce heat loss during transportation and waiting, and effectively reduce the emission of pollutants such as smoke and dust into the atmosphere. For example, CN115971469A discloses a DCAC electronic control system and control method for a mechanical intelligent cover system for molten iron mixing cars. Figure 3 As shown, this hybrid steel car 7 is equipped with an electronic control system for controlling the cover device 8. The electronic control components include a battery, battery charger, and electronic control box. These components are installed in the electrical compartment 1 at the end of the hybrid steel car 7. The electrical compartment has a left-side door and a right-side door that open outwards and are locked using conventional door locks. Because the electrical compartment is installed on the moving hybrid steel car, the car experiences significant vibration during operation. The conventional door locks in the electrical compartment frequently fail during long-term use, or cause the left-side and right-side doors to become misaligned, preventing them from closing and adversely affecting the electrical equipment inside the compartment. Therefore, it is necessary to design new locking devices on the existing left and right-side doors of the electrical compartment. Utility Model Content
