[0022] Please refer to Figures 1 to 4 , and now an experimental device provided by the present invention for studying the anxiety behavior response of animals will be described. The experimental device for studying the anxiety behavior response of animals includes a test bench 10, a rectangular frame 20, a receiving box 30, and a first driving assembly 40. Two sets of support rods 11 arranged at intervals in the front-rear direction are provided on the top of the test bench 10. The support rods 11 extend upward, and the upper ends of the support rods 11 are connected with a sliding sleeve 12 extending in the front-rear direction; the rectangular frame 20 is arranged horizontally between the two sets of support rods 11, and sliding rods 21 slidably penetrating through the sliding sleeve 12 are connected to the opposite outer side walls of the rectangular frame 20; the receiving box 30 is arranged in the rectangular frame 20 and has an upward opening for accommodating animals. A color-changing lamp 31 and a speaker 32 are provided in the receiving box 30; the first driving assembly 40 is arranged on the top of the test bench 10, and the first driving assembly 40 is connected to the sliding rod 21 on one of the sets of support rods 11 for driving the rectangular frame 20 to move horizontally.

[0023] An embodiment of the present application provides an experimental device for studying the anxiety behavior response of animals. During its actual use, an animal is first placed in the receiving box 30, and the first driving assembly 40 is used to drive the sliding rod 21 to reciprocate horizontally, so that the receiving box 30 drives the animal to shake horizontally. Moreover, in cooperation with the color-changing lamp 31 and the speaker 32, dynamic and static combined stimulation of the animal can be realized, comprehensively understanding the anxiety behavior response of the animal and improving the experimental effect.

[0024] Compared with the prior art, the experimental device for studying the anxiety behavior response of animals provided in this embodiment drives the sliding rod 21 to move back and forth horizontally through the first driving component 40, so that the containing box 30 drives the animal to shake horizontally, and can also cooperate with the color-changing light 31 and the speaker 32 to achieve dynamic and static coordinated stimulation of the animal, comprehensively understand the anxiety behavior response of the animal, and improve the experimental effect.

[0025] In a possible implementation, the container 30 is configured as follows: Figure 1 , Figure 3 and Figure 4 The structure shown, see Figure 1 , Figure 3 and Figure 4 The receiving box 30 is embedded in the rectangular frame 20 , and the top of the test bench 10 is rotatably connected to a first rotating shaft 50 extending in the left-right direction and located below the receiving box 30 . The first rotating shaft 50 is provided with a cam 51 for pushing up the receiving box 30 .

[0026] Specifically, the containing box 30 can slide up and down in the rectangular frame 20, and the first driving component 40 drives the sliding rod 21 to move back and forth horizontally, so that the containing box 30 drives the animal to shake horizontally, and then the first rotating shaft 50 is rotated to make the cam 51 repeatedly push up the containing box 30, thereby realizing the horizontal and vertical shaking of the containing box 30 at the same time, and can also shake horizontally or up and down alone, to achieve the diversity of shaking, that is, to fully understand the anxiety behavior response of the animal under dynamic stimulation.

[0027] Furthermore, the upper end surface of the rectangular frame 20 is provided with a vertical rod 22 extending upward, and the upper end of the receiving box 30 is provided with a wing plate 33 extending outward. The vertical rod 22 passes through the wing plate 33 upward, and the wing plate 33 is slidably connected to the vertical rod 22.

[0028] In some embodiments, see Figures 1 to 4 A circular gear 52 is connected to one end of the first rotating shaft 50. A second driving assembly 60 for driving the circular gear 52 is provided on the top of the test bench 10. The second driving assembly 60 includes a driving shaft 61 and a driving gear 63. The driving shaft 61 is rotatably connected to the top of the test bench 10 and is arranged parallel to the first rotating shaft 50. A motor 62 is connected to one end of the driving shaft 61. The driving gear 63 is sleeved on the driving shaft 61 and is used to mesh with the circular gear 52 to drive the circular gear 52 to rotate.

[0029] Specifically, the motor 62 drives the driving shaft 61 to rotate, so that the driving shaft 61 drives the driving gear 63 to rotate, and the driving gear 63 rotates to mesh with the circular gear 52 to drive the cam 51 to rotate, thereby realizing the automatic up and down shaking of the accommodating box 30.

[0030] The first driving component 40 can also be used to drive the sliding rod 21 to move horizontally back and forth, so that the accommodating box 30 drives the animal to shake horizontally. At the same time, the motor 62 drives the driving shaft 61 to rotate, driving the cam 51 to repeatedly push up the accommodating box 30, realizing the simultaneous horizontal and vertical shaking of the accommodating box 30.

[0031] In some embodiments, referring to Figures 1 to 4 , the driving gear 63 is slidably sleeved on the driving shaft 61, and a pushing and pulling member 64 for driving the driving gear 63 to move axially along the driving shaft 61 is provided on the driving shaft 61.

[0032] Specifically, the driving gear 63 is slidably connected to the driving shaft 61, and the pushing and pulling member 64 drives the driving gear 63 to move axially along the driving shaft 61 to realize separation from the circular gear 52. The experimenter can manually rotate the circular gear 52 to realize the automatic and manual rotation of the cam 51, avoiding the situation where the circular gear 52 cannot be rotated when the second driving component 60 is damaged.

[0033] Furthermore, a mounting platform protruding outward is provided on the outer peripheral wall of the driving shaft 61. The pushing and pulling member 64 is connected to the side of the mounting platform close to the driving gear 63. The pushing and pulling member 64 extends toward the side close to the driving gear 63 and is connected to the driving gear 63.

[0034] Furthermore, the pushing and pulling member 64 is a cylinder.

[0035] In some embodiments, referring to Figures 1 to 4 , the driving gear 63 is in a fan shape, and a radial extending pointing strip 521 is provided on the outer end surface of the circular gear 52.

[0036] Specifically, when the driving gear 63 and the circular gear 52 are in a non-engaged state, the pushing and pulling member 64 drives the driving gear 63 to move axially along the driving shaft 61, which is convenient for realizing the separation of the driving gear 63 and the circular gear 52. The experimenter can manually rotate the circular gear 52 to realize the automatic and manual rotation of the cam 51, avoiding the situation where the circular gear 52 cannot be rotated when the second driving component 60 is damaged.

[0037] Moreover, when the driving gear 63 needs to drive the circular gear 52 again, the pushing and pulling member 64 drives the driving gear 63 to move to a position where it can drive the circular gear 52, and then the circular gear 52 is manually rotated to make the pointing strip 521 in Figure 1 the vertically downward pointing state in. This state can make the driving gear 63 rotate to a perfect meshing state with the circular gear 52, avoiding the phenomenon of jamming when the driving gear 63 and the circular gear 52 are re-engaged, and there is no need to repeatedly adjust the meshing, improving the convenience of use.

[0038] In some embodiments, referring to Figures 1 to 4, on the outer side wall of the rectangular frame 20, there is a mounting plate 70 with a plate surface extending outward. On the bottom surface of the mounting plate 70, there are two guide rods 71 arranged at intervals in the front-back direction. The guide rods 71 extend downward. Between the two guide rods 71, there is a rack 72. Both ends of the rack 72 are respectively connected with guide sleeves 73. The two guide sleeves 73 are slidably sleeved on the outer peripheries of the two guide rods 71 in a one-to-one correspondence. The rack 72 is located above the circular gear 52 and is used for meshing with the circular gear 52. An elastic member 74 is sleeved on the outer periphery of the guide rod 71 and is located between the mounting plate 70 and the guide sleeve 73, and is used for elastically pushing the guide sleeve 73 downward.

[0039] Specifically, the lower end of the guide rod 71 is provided with a limiting platform that protrudes outward and is used for abutting and cooperating with the lower end surface of the guide sleeve 73.

[0040] When it is necessary for the accommodation box 30 to shake horizontally and vertically at the same time, start the push-pull member 64 to drive the driving gear 63 away from the circular gear 52. Through the elastic downward pushing of the elastic member 74 on the guide sleeve 73, the rack 72 is always in contact with the circular gear 52, that is, stably meshed. First, place the animal in the accommodation box 30, and drive the sliding rod 21 to reciprocate horizontally through the first driving assembly 40, so that the accommodation box 30 drives the animal to shake horizontally. And while shaking horizontally, the rack 72 drives the circular gear 52 to rotate, that is, drives the cam 51 to rotate, so that the accommodation box 30 shakes vertically at the same time. It can also cooperate with the color-changing lamp 31 and the speaker 32 to comprehensively understand the anxiety behavior response of the animal and improve the experimental effect.

[0041] When it is necessary for the accommodation box 30 to only shake horizontally, start the push-pull member 64 to drive the driving gear 63 away from the circular gear 52. A flexible C-shaped clamp can be clamped on the guide rod 71. The C-shaped clamp is located between the guide sleeve 73 and the limiting platform, so that the rack 72 can be separated from the circular gear 52. Drive the sliding rod 21 to reciprocate horizontally through the first driving assembly 40, so that the accommodation box 30 drives the animal to shake horizontally. It can also cooperate with the color-changing lamp 31 and the speaker 32 to comprehensively understand the anxiety behavior response of the animal and improve the experimental effect.

[0042] When it is necessary for the accommodation box 30 to only shake vertically, the push-pull member 64 drives the driving gear 63 to move to a position where it can drive the circular gear 52. The motor 62 drives the driving shaft 61 to rotate, so that the driving shaft 61 drives the driving gear 63 to rotate. The driving gear 63 rotates to mesh with the circular gear 52 to drive the cam 51 to rotate, realizing the automatic vertical shaking of the accommodation box 30. It can also cooperate with the color-changing lamp 31 and the speaker 32 to comprehensively understand the anxiety behavior response of the animal and improve the experimental effect.

[0043] In summary, the above cooperation can achieve a variety of comparisons of dynamic stimulation of animals to improve the experimental effect.

[0044] In some embodiments, refer to Figures 1 to 4, a magnet 80 is provided on the upper edge of the rack 72, and an electromagnet 81 for adsorbing the magnet 80 is provided on the bottom surface of the mounting plate 70.

[0045] Specifically, when it is necessary for the accommodation box 30 to shake horizontally only, the push-pull member 64 is activated to drive the driving gear 63 away from the circular gear 52, the electromagnet 81 is energized, the electromagnet 81 attracts the magnet 80 upward, driving the rack 72 away from the circular gear 52, realizing the rapid disengagement of the rack 72 and the circular gear 52.

[0046] It should be noted that except for the magnet 80, other components involved in this application are made of materials that do not adsorb to the electromagnet 81.

[0047] In some embodiments, refer to Figures 1 to 4 , the magnet 80 is threadedly connected to the rack 72.

[0048] Specifically, in order to ensure the stable meshing of the rack 72 and the circular gear 52, the magnet 80 can be removed, the two end faces are flipped and exchanged, and then reinstalled so that the pole of the magnet 80 that repels the electromagnet 81 faces the electromagnet 81. When the electromagnet 81 is energized, the electromagnet 81 repels the magnet 80, thereby pressing down the rack 72, and applying a double pressure to the rack 72 through the elastic member 74 and the electromagnet 81, so that the rack 72 can be further stably meshed with the circular gear 52.

[0049] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 , a plurality of accommodation boxes 30 are provided at intervals in the front-rear direction, and a first rotating shaft 50 corresponding to each of the plurality of accommodation boxes 30 is provided on the top of the test bench 10.

[0050] Specifically, a plurality of accommodation cavities are provided in the rectangular frame 20 and are arranged in one-to-one correspondence with the plurality of accommodation boxes 30. A cam 51 and a circular gear 52 are provided on each first rotating shaft 50, and each circular gear 52 is driven by a corresponding second driving assembly 60 and a rack 72, which facilitates the comparison of different accommodation boxes 30 in different shaking forms and improves the convenience of the experiment.

[0051] In a possible implementation manner, the above-mentioned first driving assembly 40 adopts the structure as shown in Figure 1 , Figure 3 and Figure 4 , refer to Figure 1 , Figure 3 and Figure 4, the first driving component 40 includes a rotary driving member 41, a rotary block 43, an eccentric shaft 44 and a driving rod 45. The rotary driving member 41 is arranged at the rear side of the rectangular frame 20 and has a driving end extending horizontally. The driving end of the rotary driving member 41 is connected with a second rotating shaft 42 extending in the left-right direction; the rotary block 43 is fixedly sleeved on the outer periphery of the second rotating shaft 42; the eccentric shaft 44 is connected to the side of the rotary block 43 far away from the second rotating shaft 42; the driving rod 45 is rotatably sleeved on the outer periphery of the eccentric shaft 44, and the outer extending end of the driving rod 45 is hinged with a hinge block 46, and the hinge block 46 is connected to the outer end of the sliding rod 21 located at the rear side of the rectangular frame 20.

[0052] Specifically, the second rotating shaft 42 is driven to rotate by the rotary driving member 41. The second rotating shaft 42 drives the rotary block 43 to rotate, and the rotary block 43 drives the eccentric shaft 44 to rotate along a fixed circular arc trajectory, so that the horizontal reciprocating movement distance of the driving rod 45 is fixed, effectively controlling the stroke of the rectangular frame 20.

[0053] Furthermore, a stabilizing block is connected to the side of the rotary block 43 far away from the eccentric shaft 44. The stabilizing block is used to offset the shaking force generated by the rotary block 43 during rotation due to pushing and pulling the driving rod 45, so that the rotary block 43 rotates smoothly.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
