Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1-5 As shown, this utility model has the following three specific embodiments.

[0020] Example 1 This utility model relates to a physiological characteristic collection device for animal experiments, comprising a feeding box 1, a space adjustment component 2, and a collection component 3. The space adjustment component 2 is disposed inside the feeding box 1 and is used to adjust the internal space size of the feeding box 1. The space adjustment component 2 includes: Partition 21 is slidably connected inside the feeding box 1; The lead screw 211 is rotatably connected to the inner wall of the back of the feeding box 1, and the outer surface of the lead screw 211 is threadedly connected to the inside of the partition 21. Worm gear 212 is rotatably connected to the left side of the feeding box 1, and the right side of worm gear 212 is fixedly connected to the left side of lead screw 211. Two support blocks 213 are fixedly connected to the left side of the feeding box 1. A worm gear 214 is rotatably connected to the corresponding side of the two support blocks 213. The top of the worm gear 214 is meshed with the bottom of the worm wheel 212. Hand crank 215 is rotatably connected to the back of support block 213 located on the back, and the front of hand crank 215 is fixedly connected to the back of worm gear 214; The collection component 3 is installed on top of the feeding box 1 and is used for collecting physiological characteristics of the animals.

[0021] like Figures 1-3 As shown, by setting up the space adjustment component 2, specifically by rotating the hand crank 215, the worm gear 214 drives the worm wheel 212 and the lead screw 211 fixed thereto to rotate, thereby driving the partition 21 to slide along the limiting rod 22, adjusting the internal space of the feeding box 1 to a range suitable for the size of the experimental animals, and improving the authenticity of the experimental data.

[0022] Two limiting rods 22 are fixedly connected to the inner wall of the back of the feeding box 1, and the outer surface of the limiting rods 22 is slidably connected to the inside of the partition 21.

[0023] The limiting rod 22 effectively limits the possibility of the partition 21 deflecting or swaying during movement, ensuring that the partition 21 always moves smoothly in the predetermined direction, thus improving the stability and reliability of space adjustment.

[0024] Example 2 The difference from Example 1 is that this example discloses the internal structure of the feeding box 1: The feeding box 1 has a door 11 hinged to the front, a mesh plate 12 fixedly connected to the bottom of the feeding box 1, and a feed trough 13 fixedly connected to the top left side of the mesh plate 12.

[0025] A manure collection box 14 is fixedly connected to the bottom of the grid plate 12, and a manure receiving tray 141 is slidably connected to the inner wall of the manure collection box 14.

[0026] A disposable absorbent pad 142 is placed on the inner wall of the manure receiving tray 141.

[0027] like Figure 4 As shown, by setting up a manure collection tray 141, the excrement produced by animals on the grid plate 12 will fall through the grid into the manure collection tray 141 below, where it will be absorbed and contained by a disposable absorbent pad 142 placed inside the tray. The manure collection tray 141 can be pulled out of the manure collection box 14, and the disposable absorbent pad 142 can be removed and replaced, thereby preventing the growth of odors and bacteria from animal excrement and ensuring a stable experimental environment.

[0028] Example 3 The difference from Embodiment 2 is that this embodiment discloses how the acquisition component 3 specifically performs the physiological feature acquisition: Acquisition component 3 includes: Turntable 31 is rotatably connected to the inner wall of the top of the feeding box 1.

Motor 312 is fixedly connected to the top of the feeding box 1, and the bottom output end of motor 312 is fixedly connected to the top of turntable 31.

[0029] like Figure 5 As shown, the motor 312 drives the turntable 31 to rotate multiple cameras 311, realizing data collection from multiple angles and without blind spots inside the feeding box 1, thus improving the comprehensiveness and automation of data collection.

[0030] One specific application of this embodiment is as follows: In use, first turn the hand crank 215, which drives the worm gear 214 to drive the worm wheel 212 and the lead screw 211 fixed thereto to rotate, thereby driving the partition 21 to slide along the limiting rod 22, adjusting the internal space of the feeding box 1 to a range suitable for the size of the experimental animals. Open the box door 11, put the experimental animals into the feeding box 1, and add sufficient feed to the feed trough 13. Then close the box door 11, collect animal behavior characteristics through the camera 311. When it is necessary to change the shooting angle, start the motor 312 to drive the turntable 31 and several cameras 311 to rotate, thereby collecting multi-angle, no-dead-angle image and video data. The excrement produced by the animals on the grid plate 12 will fall through the grid into the manure collection tray 141 below, which is absorbed and contained by the disposable absorbent pad 142 placed in the tray. Pull out the manure collection tray 141 in the manure collection box 14, take out and replace the disposable absorbent pad 142, and the cleaning work can be completed.
