TECHNICAL FIELD

[0001] The utility model relates to experimental animal breeding technical field, concretely relates to experimental animal breeding transfer device. BACKGROUND

[0002] Experimental animals play an extremely important role in promoting the development of medical science, scientists use animals such as dogs, frogs, snakes, fish, cattle, sheep, rabbits, mice as experiments, through the experiment and observation of animals, scientists can understand the various laws of organic world, thereby promoting the development of medical science, and experimental animals can provide a large amount of data similar to human life activity phenomena, through experimental animals, scientists can use less human, material and time to find out the relationship between single factor and result. These data have important significance for understanding the pathogenesis, prevention and treatment method of human diseases;

[0003] Experimental rabbit needs to go through disinfection, daily breeding, breeding, transfer and experiment when breeding, and needs to transfer experimental rabbit after experimental rabbit breeding or before experiment, if young rabbit is transferred, only needs to use clamp to clamp young rabbit and transfer, and if adult rabbit is transferred, needs staff to manually grab rabbit, or drives rabbit into transfer device, or puts food to lure rabbit to jump into transfer device.

[0004] But the existing experimental animal transfer device has some defects, for example:

[0005] When staff drives rabbit or grabs rabbit, rabbit can resist and bite or scratch staff, there is a risk of injury, so the existing transfer device is not convenient to take out rabbit without staff contacting experimental rabbit.

[0006] Therefore, the utility model provides an experimental animal breeding transfer device to solve the above problems. UTILITY MODEL CONTENT

[0007] In view of above situation, in order to overcome the defects of prior art, the utility model provides an experimental animal breeding transfer device to solve the above problems.

[0008] In order to realize the above purpose, the utility model takes the technical scheme that:

[0025] Preferably, a side blocking frame is fixed to the side of the bottom door, and the side blocking frame is located outside the cage.

[0026] Through the above technical scheme, the side blocking frame prevents the experimental rabbit from jumping out of the gap between the bottom grid and the side of the cage.

[0027] Preferably, the lower end of the cage is fixed with a base, the upper side of the base is fixed with a support frame, and the support frame is located below the bottom door.

[0032] In summary, when the bottom grid is horizontal and the fixed grid is vertical, the bottom grid can be fixed by the clamping assembly, the experimental rabbit moves on the bottom grid, and the excrement of the experimental rabbit is discharged downward through the bottom grid and the bottom door, so that the experimental rabbit can be bred for a short time by using the device, and the experimental rabbit can still move normally during the transfer process.

[0033] When the experimental rabbit needs to be transferred, the clamping assembly can be disassembled to make the bottom grid rotate downward, the elastic cloth and the elastic belt hold the bottom door, at this time, the filling blocks in the bottom door are inserted into the impurity outlet of the bottom grid, so that the upper surface of the bottom grid is flat, the experimental rabbit can be actively slid out of the animal outlet of the cage, and the elastic cloth can prevent the experimental rabbit from jumping, thereby limiting the experimental rabbit from falling into the external experimental rabbit breeding cage from between the elastic cloth and the bottom grid.

[0034] In conclusion, the device can temporarily breed experimental rabbits, ensure that the experimental rabbits can move normally during the transfer process, and only need to open the fixed grid and the bottom grid when the experimental rabbits are transferred, so that the experimental rabbits can slide out of the device, and then the experimental rabbits can be quickly taken out, and the whole process does not need the staff to contact the experimental rabbits, so that the safety of the staff is ensured.
