[0002] Laboratory animals play an irreplaceable role in scientific research and drug development. The study of their behavioral and physiological response characteristics is of vital importance in revealing the complex pathogenesis of human diseases and accurately evaluating the efficacy and safety of potential therapeutic drugs. In order to simulate experimental conditions and control experimental parameters, researchers usually need to place laboratory animals in various devices for behavioral observation and physiological monitoring.

[0003] The Activity Wheel is a device suitable for small animal experiments and is widely used in small animal behavior, exercise physiology, pharmacology, neurophysiology and other studies. Taking the study of animal depression as an example, animals suffering from the disease often show symptoms such as reduced activity and mental depression. In response to these symptoms, researchers will carry out targeted rehabilitation treatment. After completing the rehabilitation treatment of the animal, it is often impossible to accurately quantify its degree of recovery by simply observing the animal's movement behavior with the naked eye.

[0004] Although existing running wheels provide space for exercise, their functions are relatively simple and they lack the ability to record and analyze animals' movement behaviors in detail, which limits researchers' ability to make scientific and objective assessments. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides an animal experiment running wheel, such as Figure 1 As shown, it comprises: a base frame 1, a rotating wheel 2 is rotatably connected inside the base frame 1, and a counting component 3 is arranged between the rotating wheel 2 and the base frame 1.

[0027] In one embodiment of the present invention, Figure 2As shown, the counting component 3 includes: a connecting frame 31 and a bottom frame 32, the connecting frame 31 is installed on the outer wall of the rotating wheel 2, a paddle 311 is provided at the center of the bottom of the connecting frame 31, the bottom frame 32 is arranged at the top of the bottom frame 1 opposite to the connecting frame 31, a convex piece 321 is rotatably connected inside the connecting frame 31, the position of the convex piece 321 is opposite to the position of the paddle 311, a pressing piece 322 is provided at the bottom of the convex piece 321, and a counter 34 is provided at the top of the bottom frame 32 opposite to the pressing piece 322, a reset spring 33 is arranged between the pressing piece 322 and the bottom frame 32, the top end of the reset spring 33 is fixedly connected to the bottom of the pressing piece 322, and the bottom end of the reset spring 33 is fixedly connected to the top of the bottom frame 32.

[0028] It should be noted that: when in use, after placing the animal that needs to exercise inside the rotating wheel 2, the rotating wheel 2 can be manually turned to rotate the rotating wheel 2. At this time, the animal inside the rotating wheel 2 can run along with the rotation of the rotating wheel 2 for position balance when the rotating wheel 2 rotates. During the running of the animal, the driving force on the rotating wheel 2 can be increased to make the rotating wheel 2 rotate continuously. During this process, the counting component 3 located below the rotating wheel 2 can count the number of rotations of the rotating wheel 2. Then, the excitement state of the animal can be judged by analyzing the number of rotations of the rotating wheel 2 during each movement of the animal, and the recovery state of the animal can be judged.

[0029] By setting the reset spring 33, after the paddle 311 squeezes the protruding piece 321 each time, the reset spring 33 can smoothly drive the protruding piece 321 and the pressing piece 322 to reset through its own prestress generated by the twisting, so that the paddle 311 can still move the protruding piece 321 when it rotates next time, so that the pressing piece 322 can squeeze and count the counter 34 smoothly.

[0030] In this embodiment, Figure 3 As shown, a mounting frame 4 is provided on one side of the top of the base frame 1, and a fixedly connected protruding rod 41 and a rotatably connected rotating rod 42 are provided on the top of the mounting frame 4, a connecting piece 43 is arranged between the protruding rod 41 and the rotating rod 42, the inner wall of the connecting piece 43 is slidably connected to the outer wall of the protruding rod 41, and the inner wall of the connecting piece 43 is threadedly connected to the outer wall of the rotating rod 42, a supporting frame 44 is provided on the top of the connecting piece 43, a motor 45 is provided on one side inside the supporting frame 44, a rotating shaft 46 is provided at the output end of the motor 45, and the end of the rotating shaft 46 away from the motor 45 is rotatably connected to the inner wall of the supporting frame 44, a fixedly connected first pulley 47 is sleeved on the outer wall of the rotating shaft 46, a transmission-connected belt 48 is sleeved on the outer side of the first pulley 47, a transmission-connected second pulley 49 is sleeved on the lower part of the belt 48, and the second pulley 49 is fixedly sleeved on the outer wall of the shaft connecting the rotating wheel 2 and the base frame 1.

[0031] It should be noted that: the rotating shaft 46 is connected to the shaft between the base frame 1 and the rotating wheel 2 by means of a belt 48, a first pulley 47 and a second pulley 49. When in use, the tightness between the belt 48 and the first pulley 47 and the second pulley 49 can be smoothly controlled to control the linkage state between the rotating wheel 2 and the shaft. When it is necessary to apply a continuous force to the rotating wheel 2, the rotating rod 42 can be controlled to mobilize the connecting piece 43 to move downward, so that the connecting piece 43 can smoothly drive the internal motor 45, the rotating shaft 46, the first pulley 47 and the belt 48 to move downward through the top support frame 44, and then the belt 48 and the first pulley 47 and the second pulley 49 can be smoothly placed in a relaxed state. When the rotating wheel 2 rotates, the second pulley 49 will not drive the belt 48 to rotate, so that the rotating wheel 2 can smoothly rotate independently.

[0032] On the contrary, during use, when it is necessary to perform exercise rehabilitation treatment on an animal with a relatively small body or a relatively serious depression, the rotating rod 42 can be controlled to rotate in the reverse direction, so that the belt 48 can smoothly abut against the first pulley 47 and the second pulley 49, and then the motor 45 can be controlled to work, so that it drives the rotating wheel 2 to rotate to achieve active driving of the rotating wheel 2, thereby allowing the relatively small body or the animal with a relatively serious depression to perform passive exercise rehabilitation exercises inside the rotating wheel 2;

[0033] A protruding rod 41 is slidably connected inside the connecting piece 43. When the rotating rod 42 is controlled to rotate later, the protruding rod 41 limits the inside of the connecting piece 43, so that the connecting piece 43 can be prevented from rotating with the rotation, thereby allowing the connecting piece 43 to stably move in the vertical direction later.

[0034] In this embodiment, if Figure 4 , Figure 5 and Figure 6 As shown, a movably connected door frame 5 is provided on one side wall of the rotating wheel 2, the bottom of the door frame 5 is rotatably connected to the outer wall of the rotating wheel 2 through a rotating structure, and the inside of the door frame 5 and the side wall of the rotating wheel 2 are inlaid with transparent glass, and a fixed plate 51 is fixedly connected on the top of the door frame 5. Further, a support plate 21 is provided at a position opposite to the outer wall of the rotating wheel 2 and the fixed plate 51, a threaded connecting pin 22 is inserted into the inside of the support plate 21, and the outer wall of the connecting pin 22 is threadedly connected to the inner wall of the fixed plate 51.

[0035] It should be noted that by inlaying transparent glass on the inside of the door frame 5 and the side wall of the rotating wheel 2, the transparent glass can enable people to see the condition of the animals inside the rotating wheel 2 more intuitively when using the device, thereby reducing the phenomenon of accidental injury to the animals during use. By connecting the connecting pin 22 with the fixing plate 51 and the supporting plate 21 through a threaded structure, the connection to the door frame 5 can be smoothly fixed.

[0036] The working principle of the animal experiment running wheel provided in this embodiment is as follows:

[0037] When using the device, first open the door frame 5, place the animal to be treated inside the rotating wheel 2, then close the door frame 5, and fix the door frame 5 by connecting the connecting pin 22 with the fixed part, and then start the rotating force of the rotating wheel 2 to rotate the rotating wheel 2.

[0038] During this process, the animal inside the rotating wheel 2 can smoothly run in the opposite direction inside the rotating wheel 2 in order to maintain its own stability. During the running process, the friction force of the animal's limbs on the inner wall of the rotating wheel 2 can be smoothly converted into a driving force for the rotating wheel 2, thereby allowing the rotating wheel 2 to continue to rotate.

[0039] During the rotation of the rotating wheel 2, when the paddle 311 on the outer wall connecting frame 31 of the rotating wheel 2 rotates to the bottom and abuts against the convex piece 321, the convex piece 321 can be smoothly rotated inside the bottom frame 32. At this time, the rotating convex piece 321 drives the pressing piece 322 on the outer wall to move smoothly toward the direction of the counter 34 below, so that the pressing piece 322 can smoothly squeeze the counter 34. At this time, the counter 34 can smoothly record the number of rotations of the rotating wheel 2.

[0040] When the rotating wheel 2 stops rotating, the data recorded by the counter 34 for each movement of the animal can be analyzed to obtain the excitement state of the animal in this exercise training, thereby facilitating personnel to assist in judging the recovery state of the animal's depression treatment.

[0041] At the same time, during use, the rotating rod 42 is controlled to rotate, so that it drives the connecting piece 43 to move on the outer wall of the protruding rod 41 through the threaded structure, and then drives the internal motor 45, the rotating shaft 46, the first pulley 47 and the belt 48 to move upward at the same time through the support frame 44 on the outer wall, until the lower part of the belt 48 hits the inner wall of the second pulley 49, and the rotation of the rotating rod 42 can be stopped.

[0042] At this time, the animal that needs to be exercised can be placed inside the rotating wheel 2, and the motor 45 can be controlled to work. The working motor 45 can drive the external first pulley 47 to rotate through the rotating shaft 46, and the rotating first pulley 47 can drive the belt 48 to rotate through the friction between the belt 48. At this time, the rotating belt 48 can smoothly drive the rotating wheel 2 to rotate through the second pulley 49, so that the rotating wheel 2 can rotate at a uniform speed, and the animals with relatively severe depression or relatively small size located inside the rotating wheel 2 can be subjected to passive exercise training, thereby improving the functionality of the device in later use.

[0043] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0044] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
