[0020] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0021] Embodiment 1: A new type of animal treadmill for mouse experiments, see Figures 1 to 5, including a box body 1. On both sides of the bottom end of the inner cavity of the box body 1, multiple groups of connecting frames 43 are installed. Inside each group of connecting frames 43, a driving shaft 42 is rotatably connected. On the outer sides of multiple groups of driving shafts 42, driving rollers 41 are fixedly connected. On the driving rollers 41 between multiple groups on both sides of the inner cavity of the box body 1, running belts 4 are installed. On one side of each group of connecting frames 43, a servo motor 44 is installed. The driving ends of multiple servo motors 44 are respectively connected to multiple driving shafts 42; on the top of the box body 1, a box cover 2 is provided. The box cover 2 is a transparent cover. At one end of the box cover 2, multiple T-shaped partitions 26 are installed. On one side of the surface of the box cover 2, a rectangular hole 23 is opened. On the box cover 2 on one side of the rectangular hole 23, a hinge 24 is installed. The box cover 2 is hinged with a sealing plate 25 through the hinge 24. At the four corners of the box cover 2, bolts 21 penetrate through, and all four bolts 21 are threadedly connected to the surface of the box body 1. During work, place the box cover 2 at the top opening of the box body 1, and then turn the bolts 21 to fix the box cover 2, so as to cooperate with the T-shaped partitions 26 to independently divide multiple running belts 4 and fit them on both sides of the running belts 4. Then, open the sealing cover through the hinge 24 and put the experimental mice into the corresponding running belts 4 through the rectangular hole 23. Then, close the rectangular hole 23 through the sealing cover. Then, control the rotation speeds of multiple servo motors 44 through a motor controller (not described in detail in the prior art), so that the moving speeds of multiple running belts 4 can be inconsistent, so that when it is necessary to study the indicators of mice at different speeds, it can be achieved in one experiment without multiple experiments, thereby improving the efficiency of mouse research.

[0022] Specifically, refer to Figure 1 and Figure 2 , a bottom plate 3 is provided below the box body 1. On both sides of the surface of the bottom plate 3, connecting plates 31 are fixedly connected. At the opposite ends of two connecting plates 31, fixed shafts 32 are rotatably connected. The other ends of two fixed shafts 32 are respectively fixedly connected to both ends of the box body 1. On the surface of the bottom plate 3, an adjustment groove 35 is opened. Between the two sides of the inner cavity of the adjustment groove 35, a lead screw 37 is rotatably connected. In the adjustment groove 35, an adjustment block 36 is slidably connected, and the adjustment block 36 is threadedly sleeved on the outer side of the lead screw 37. On the surface of the adjustment block 36, a wedge block 34 is fixedly connected. By turning the lead screw 37 to rotate and cooperating with the guiding movement of the adjustment block 36 in the adjustment groove 35, the adjustment block 36 can be driven to move in the adjustment groove 35, so as to adjust the position of the wedge block 34 on the bottom plate 3. Cooperating with the rotation connection of one end of the box body 1 through the fixed shaft 32, the inclination angle of the box body 1 can be adjusted, and then the slope of the running belt 4 can be adjusted, so as to study the reaction and adaptability of mice under different conditions.

[0023] Furthermore, refer to Figure 1 , multiple ventilation holes 22 are opened on the surface of the box cover 2. Multiple ventilation holes 22 respectively correspond to multiple running belts 4. Through the arrangement of the ventilation holes 22, sufficient air in the box body 1 can be ensured for the breathing of mice.

[0024] It should be noted that, referring to Figure 1 , a heat dissipation hole 11 is provided at one end of the box body 1 away from the wedge block 34. Through the heat dissipation hole 11, the heat generated by the operation of the servo motor 44 in the box body 1 can be discharged, avoiding heat accumulation in the box body 1 and causing damage to the servo motor 44.

[0025] It is worth noting that, referring to Figure 1 , horizontal support blocks 33 are fixedly connected to both sides of one end of the bottom of the box body 1 close to the wedge block 34. Through the arrangement of the horizontal support blocks 33, when the horizontal support blocks 33 contact the bottom plate 3, the box body 1 remains horizontal, thereby facilitating the quick adjustment of the box body 1 to a horizontal state.

[0026] It is worth introducing that, referring to Figure 2 , one end of the lead screw 37 rotates through the bottom plate 3 and is located outside the bottom plate 3. A hand wheel 38 is fixedly connected to the lead screw 37 outside the bottom plate 3. Through the arrangement of the hand wheel 38, it is convenient for personnel to hold, and thus convenient for personnel to manually drive the lead screw 37 to rotate to adjust the inclination angle of the box body 1.

[0027] In addition, the components designed in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. Those skilled in the art can fully implement them without further elaboration.
