The independent ventilation experimental cage (IVC) is characterized in that in a sealed independent unit (cage box or cage tool), clean air flow is independently ventilated with high ventilation rate, waste gas is concentrated and discharged, and SPF-level experimental animal raising and living places of animal experiments are provided. The IVC cage box has the functions of sterilizing, reusing and sealing and isolating from natural environment. For the purposes of conveniently managing experimental animals, increasing the space utilization rate of a laboratory, reducing the energy use and the like, various cage boxes are mostly stacked on a cage frame in a layer-by-layer manner and are in a rectangular design.

3. If the hasp adopts a left-right placement mode, the hasp is difficult to avoid damaging or falling off due to collision with the cage when the cage is taken and placed on the cage. At present, most of the buckles are placed front and back, but the buckles are placed on two side edges of a shorter cage box in the mode, the phenomenon of loose sealing is often caused on two side edges of the longer cage box, and the buckles are likely to be impacted by collision and falling in the daily management or observation process due to the fact that one side of each buckle is located in a laboratory channel.
4. The opening and closing operation of the cage box is not convenient and quick enough (the operation process of closing the cage box is that the hasp blocks at two sides are pulled outwards to enable the cage cover to cover the cage bottom, then the hasp blocks are buckled on the corresponding clamping grooves of the cage bottom, and finally the hasp is compressed, and the operation process of opening the cage box is opposite).
