  • Patent number: 10071751
    Abstract: A mounting structure for equipment compartment bottom plate is provided. The bottom plate is detachably connected to a skeleton boundary beam of the equipment compartment. A sliding rail is fixedly connected to a side of the bottom plate where the bottom plate is lap-jointed to a skeleton lateral beam of the equipment compartment. One of the sliding rail and the skeleton lateral beam is provided with a recess and the other is provided with a protrusion engaged with the recess. In the mounting structure, the connection of the bottom plate and the skeleton lateral beam is achieved by the engagement of the recess and the protrusion. Therefore, connecting pieces for connecting the bottom plate and the skeleton lateral beam are removed and the number of the connecting pieces is significantly reduced.
