[0027] The utility model aims at providing an experimental animal transport box, which is further described below in combination with specific embodiments.

[0028] As Figure 1 shown, the experimental animal transport box has a box body 10. Four universal wheels 14 are arranged on the bottom of the box body 10. A drawbar can also be hingedly connected to the outer wall of the box body 10 for use during transportation. Figure 3 As Figure 2 shown, the upper part of the box body 10 is open, and a box cover 12 is hingedly connected to the opening. The front part of the box body 10 is provided with a cleaning port 11 and a first air window 13, and the first air window 13 is located above the cleaning port 11. Figure 4As shown, the inner cavity 16 of the box 10 is horizontally provided with a limiting plate 18 on each of the left and right inner walls. A lifting frame 4 is installed in the inner cavity 16, and two hooks 40 are installed on each of the left and right sides of the lifting frame 4. The two hooks 40 on the left side cooperate with the limiting plate 18 on the left side, and the two hooks 40 on the right side cooperate with the limiting plate 18 on the right side. A mesh plate 41 is installed on the lifting frame 4. The lifting frame 4 and the mesh plate 41 are detachably matched. A collection box 3 is installed in the cleaning port 11, and the collection box 3 is located below the mesh plate 41. A recycling hopper 30 is installed in the collection box 3, and a sewage pipe 31 is provided at the lowest position of the bottom of the recycling hopper 30. A one-way valve 32 is installed at the outlet of the sewage pipe 31.

[0029] In use, the box cover 12 is opened, the experimental animals such as mice or rabbits are placed on the mesh plate 41, and then the box cover 12 is buckled and locked, which is very convenient to operate. During the transportation process, the feces and urine of the animals can fall into the recycling hopper 30 through the holes in the mesh plate 41. Under the action of gravity, the feces and urine will enter the collection box 3 at the bottom for storage through the sewage pipe 31. In order to prevent urine from splashing and causing pollution during transportation, and to keep the area where the animals are placed as clean as possible, a one-way valve 32 can be installed at the outlet of the sewage pipe 31. The feces and urine can pass through the sewage pipe 31 and push open the one-way valve 32 under the action of gravity, and finally enter the bottom of the collection box 3. After the recycling hopper 30 is emptied of feces and urine, the one-way valve 32 will automatically close.

[0030] The existing transport box also has the following design problems: when the experimental personnel need to take out the animals, they often need to operate inside the box, which not only increases the difficulty and complexity of the operation, but also may cause unnecessary disturbance and harm to the experimental animals. In order to solve this problem, the following scheme is designed in the present application:

[0031] As shown in Figure 4 , a wheel set mechanism 2 is installed in the inner cavity 16. The wheel set mechanism 2 includes a fixed shaft 20 and a rotating shaft 20a, which are arranged in parallel. As shown in Figure 7 , a first wire wheel 21 and a chain wheel 61 are fixedly installed on the rotating shaft 20a. As shown in Figure 8 , a second wire wheel 23 and a third wire wheel 27 are fixedly installed on the rotating shaft 20a. As shown in Figure 4 and Figure 6 , a first fixed pulley 22 and a second fixed pulley 28 are respectively installed on the fixed shaft 20. As shown in Figure 4As shown, the side wall of the box 10 is vertically provided with a strip-shaped through slot 17, and the inner and outer sides of the strip-shaped through slot 17 are respectively provided with an inner sliding block 51 and an outer sliding block 50. The outer sliding block 50 and the inner sliding block 51 are connected through a connecting piece, and the connecting piece is located in the strip-shaped through slot 17 and can slide up and down along the strip-shaped through slot 17. A chain 60 is installed on a sprocket wheel 61, and the chain 60 is engaged with the sprocket wheel 61. The inner sliding block 51 is connected to one end of the chain 60, and the other end of the chain 60 is connected to a hook 40. A first wire wheel 21 is connected to one end of a first steel wire rope 24, and the other end of the first steel wire rope 24 is connected to a hook 40 through a first fixed pulley 22. A second wire wheel 23 is connected to one end of a second steel wire rope 25, and the other end of the second steel wire rope 25 is connected to a hook 40. A third wire wheel 27 is connected to one end of a third steel wire rope 26, and the other end of the third steel wire rope 26 is connected to a hook 40 through a second fixed pulley 28. That is, the four hooks 40 on the lifting frame 4 are respectively connected to the chain 60, the first steel wire rope 24, the third steel wire rope 26, and the second steel wire rope 25 one by one. In order to facilitate the force on the outer sliding block 50, a pull ring can be hinged on the outer sliding block 50. When the animal needs to be taken out of the inner cavity 16, the box cover 12 can be opened, and then the pull ring is pulled to pull the outer sliding block 50 upward by a distance. During this process, the outer sliding block 50 pulls the chain 60 downward, and the chain 60 exerts an upward pulling force on the hook 40 connected thereto on one hand, and on the other hand, the chain 60 drives the rotating shaft 20a to rotate, and the rotating shaft 20a synchronously drives the first wire wheel 21, the second wire wheel 23, and the third wire wheel 27 to rotate. The first wire wheel 21, the second wire wheel 23, and the third wire wheel 27 synchronously exert an upward pulling force on the corresponding hook 40 through the first steel wire rope 24, the second steel wire rope 25, and the third steel wire rope 26, respectively, so that the lifting frame 4 with the animal is smoothly moved upward by a certain height. In this way, it is more convenient for the staff to take the animal.

[0032] In order to facilitate the operation of the staff, a positioning hook can also be installed on the box 10 below the strip-shaped through slot 17. When the staff pulls the outer sliding block 50 downward by using the pull ring, the pull ring can be hung on the positioning hook to be fixed, so that the pull ring is locked. At this time, the height of the lifting frame 4 is locked, and one staff can easily complete the above work.

[0033] In order to further simplify the operation and improve the work efficiency, the following scheme can also be designed: a lever 52 is installed on the box cover 12, one end of the lever 52 is hinged to one end of a connecting rod 53, and the other end of the connecting rod 53 is hinged to the outer sliding block 50. Figure 5 As shown, when the staff opens the box cover 12, the outer sliding block 50 can be pushed downward through the lever 52 and the connecting rod 53, so that the lifting frame 4 is moved upward.

[0034] In addition, the design also can play a self-locking function: when the animal stands on the lifting frame 4, it cannot open the box cover 12 upward. Because the force is mutual, when the animal forces the box cover 12 with the lifting frame 4, the lifting frame 4 will also be subjected to a force equal in size but opposite in direction, which will rotate the box cover 12 through the wheel group mechanism 2 and the driving mechanism 5, so that the box cover 12 cannot be pushed open from the inside.

[0035] The collecting box 3 is provided with a handle, which facilitates the worker to take out the collecting box 3 for cleaning.

[0036] The recycling hopper 30 is detachably connected with the collecting box 3, and two limiting protrusions 33 are arranged on the left and right inner walls of the collecting box 3. The limiting protrusions 33 are matched with the recycling hopper 30. When the collecting box 3 is taken out, the recycling hopper 30 can also be taken out from the collecting box 3 for cleaning. Similarly, the mesh plate 41 can also be separated from the lifting frame 4 for cleaning.

[0037] The technical scheme of the utility model is not limited to the scope of the embodiments described in the utility model. The technical contents not described in the utility model are all known technologies.
