[0041] Currently, in order to develop treatment methods for motor function disorders, animal models with disease pathophysiology comparable to that of clinical populations are commonly used. During the research process, it is often necessary to detect the motor ability of small animals, and one of the detection methods is the mouse wire suspension test. When testing, a platform needs to be built, and a metal wire 50 - 60 cm above the ground is set up for the mouse to walk on the wire for testing. During the testing process using the current detection device, when the animal is placed on the wire, due to the lack of a sense of security of the animal, it is very easy to lose its footing and directly fall from the wire. It requires the experimenter to train the animal multiple times to grasp the wire and hang, which consumes a large amount of experimental time, and multiple falls may pose a threat to the safety of the animal. To address the above technical problems, the present utility model provides a detection device for detecting the motor ability of animals, which can provide a balance point for the animal to initially stand firm during the testing process, and the balance point can be adjusted and removed as needed, having the advantage of high flexibility in use. The technical solutions of the present utility model will be described in detail below with specific examples.

[0042] Refer to Figure 1 、 Figure 2 and Figure 3As shown, a detection device for detecting the motor ability of animals according to the present utility model includes a support rod 10, a steel wire assembly 20, and a positioning frame 30. Among them, there are 4 support rods 10, and two steel wire assemblies 20 are provided. The steel wire assembly 20 includes a steel rope 201 and a building member 202 provided at both ends of the steel rope 201. The building member 202 is detachably connected to the support rod 10. The two steel wire assemblies 20 are connected to the 4 support rods 10 through the corresponding building members 202, and the two steel ropes 201 intersect with each other, and the intersection point forms a balance point for the animal to stand firm. The positioning frame 30 is detachably connected to the support rod 10 to position and fix the support rod 10.

[0043] Exemplarily, when using this device to conduct a steel wire suspension test on an animal, first assemble the support rod 10 and the positioning frame 30, and then install the steel rope 201 on the support rod 10 through the building member 202. After the installation is completed, the two steel ropes 201 intersect with each other, and a balance point for the animal to stand firm is formed at the intersection point. When the animal is placed at the cross-shaped balance point, the balance point can facilitate the animal's four limbs to grasp. After the animal is familiar with the detection environment, slowly remove one of the steel wires. The animal can quickly maintain balance, grasp the steel wire and keep its body suspended or move along the steel wire towards the support rods 10 at the four corners. Among them, the provision of the balance point can greatly save the experimental time. During the test process, a balance point for the animal to initially stand firm can be provided, avoiding the damage caused by the animal falling multiple times due to difficulty in getting familiar with the initial grasp, improving the safety of the experimental animals, and the balance point can be adjusted and removed according to needs, having the advantage of high flexibility in use and facilitating the tester to evaluate the motor coordination ability of the animal.

[0044] In an embodiment, the overall structure of the positioning frame 30 is further refined. The positioning frame 30 includes a positioning rod 301 and a limit pin 302. Among them, there are two positioning rods 301. The two positioning rods 301 are vertically spaced and horizontally connect the support rods 10 in the diagonal direction. The end of the positioning rod 301 is provided with a threaded connection with the support rod 10. At the same time, positioning holes 303 are correspondingly opened at the intersection of the two positioning rods 301, and the limit pin 302 is inserted into the two positioning holes 303 to limit the relative rotation of the two positioning rods 301.

[0045] Exemplarily, when the support rod 10 and the positioning frame 30 in the present device need to be assembled, both ends of two of the positioning rods 301 are threadedly connected to two support rods 10. It should be noted that since the two positioning rods 301 are vertically spaced, the connection structures on the corresponding support rods 10 are adjusted adaptively according to their heights. After the installation between the positioning rod 301 and the support rod 10 is completed, the four support rods 10 are erected, and the two positioning rods 301 are intersected. At this time, the positioning holes 303 on the two positioning rods 301 are correspondingly arranged at the intersection. By inserting the limit pin 302 into the two positioning holes 303, as shown in the figure, the two positioning rods 301 can be positioned and fixed, and at this time, the assembly between the support rod 10 and the positioning frame 30 is completed.

[0046] In this embodiment, specifically, a collar 101 is sleeved on the support rod 10. The collar 101 is rotatably connected to the support rod 10, and the end of the positioning rod 301 is rotatably connected to the collar 101.

[0047] In order to correspond to two positioning rods 301 of different heights, the heights of the collar 101 and the corresponding positioning rod 301 are correspondingly set, as Figure 1 shown. The structure of the rotational connection can facilitate the assembly of the positioning rod 301 and the support rod 10 and improve the flexibility of the operation.

[0048] In one embodiment, the overall structure of the support rod 10 is further refined. The support rod 10 includes a fixed section 102 and a telescopic section 103. The telescopic section 103 is slidably connected to the fixed section 102, and the top of the fixed section 102 is open for the telescopic section 103 to be telescopically adjusted. The two are combined to form a rod body with a telescopic adjustment function. The support rod 10 further includes a limiting member 104. The limiting member 104 is arranged on the fixed section 102 to position and fix the telescopic section 103.

[0049] It should be noted that the telescopic adjustment structure of the support rod 10 enables the height of the support rod 10 to be adjustable. During the experiment, the installation height of the steel rope 201 can be adjusted according to actual needs. In addition, during the experiment, by synchronously adjusting the heights of the support rods 10 on the same diagonal, the effect of removing one steel rope 201 can also be achieved. The setting of this structure can provide an additional experimental method for the experimenter to choose.

[0050] In order to improve the support stability of the support rod 10, a rubber gasket 105 is arranged at the bottom of the fixed section 102.

[0051] In this embodiment, specifically, the limiting member 104 is a limiting bolt. The limiting bolt is threadedly connected to the fixed section 102, and the bottom of the limiting bolt presses against the outer edge of the telescopic section 103.

[0052] Exemplarily, when it is necessary to adjust the height of the support rod 10, loosen the corresponding limit bolt, adjust the height of the telescopic section 103. After adjusting to the required height, tighten the limit bolt again. The bottom of the limit bolt presses tightly against the outer edge of the telescopic section 103 to position and fix the telescopic section 103. By correspondingly adjusting each support rod 10, the height adjustment of the steel cable 201 can be completed.

[0053] In an embodiment, the overall structure of the erection member 202 is further refined. Among them, an installation hole 106 is opened at the top of the telescopic section 103. The erection member 202 includes a column body 2021 and a connecting member 2022. The column body 2021 is inserted into the installation hole 106, the connecting member 2022 is arranged at the top of the column body 2021, and the steel cable 201 is connected to the connecting member 2022. In this embodiment, the connecting member 2022 is rotatably connected to the column body 2021.

[0054] Among them, in order to enable the erection member 202 to have relatively high structural connection stability, the column body 2021 and the installation hole 106 are arranged in an interference fit.

[0055] It should be noted that this device can also be equipped with a storage box. Since all the components of this device are rod-shaped structures and have high-efficiency and convenient disassembly and assembly performance among each other, after the components are disassembled, they can be stored in the storage box. When the experiment needs to be carried out next time, take them out again for assembly.

[0056] Refer to Figure 4 As shown, in an embodiment, a shielding enclosure 40 is sleeved outside the support rod. After the support rod 10 and the positioning frame 30 are assembled, the shielding enclosure 40 can be integrally sleeved outside the 4 support rods 10 to shield the inside, creating a sense of spatial safety atmosphere for the experimental object animals. The setting of the shielding enclosure 40 can further optimize the operation stability of the experiment.

[0057] And in this embodiment, more preferably, refer to Figure 5 As shown, in order to facilitate the disassembly and storage of the shielding enclosure 40, the shielding enclosure 40 is composed of 4 plates 401 spliced together. The adjacent plates are spliced and connected through the mutually matching grooves 402 and protrusions 403.

[0058] Specific implementation process:

[0059] When using this device to conduct the wire suspension test on animals, first assemble the support rod 10 and the positioning frame 30. Thread both ends of two of the positioning rods 301 to the two support rods 10. After completing the installation between the positioning rod 301 and the support rod 10, place the four support rods 10 vertically, making the two positioning rods 301 intersect. At this time, the positioning holes 303 on the two positioning rods 301 are correspondingly arranged at the intersection. Insert the limit pin 302 into the two positioning holes 303 to complete the assembly between the support rod 10 and the positioning frame 30;

[0060] Subsequently, install the steel rope 201 on the installation hole 106 of the support rod 10 through the column 2021 of the erection member 202. After installation, the two steel ropes 201 intersect, and a balance point for the animal to stand firm is formed at the intersection point;

[0061] In the laboratory, place the animal at the balance point of the cross. The balance point facilitates the animal's four limbs to grasp. After the animal gets familiar with the detection environment, slowly withdraw one of the steel wires. The animal can quickly maintain balance, grasp the steel wire to keep its body suspended or move along the steel wire towards the support rod 10 at the four corners.

[0062] The present utility model also provides a specific experimental method. After completing the assembly of the device, place the animal at the balance point. After it gets familiar with the steel wire and the environment, due to its natural instinct of freely exploring and climbing, it will randomly climb in any direction of the cross-shaped steel wire. At this time, the operator can slowly withdraw one of the steel wires, observe its climbing behavior on the steel wire, and conduct scoring.

[0063] Score 4: Move from the balance point towards any one of the steel wires, grasp with the front and rear claws in coordination, and move a certain distance;

[0064] Score 3: Move from the balance point towards any one of the steel wires, grasp with the front or rear claw, and move a certain distance;

[0065] Score 2: Move from the cross intersection towards any one of the steel wires, grasp with the front or rear claw, and cannot move a distance;

[0066] Score 1: Unable to move from the cross intersection towards any one of the steel wires, or unable to grasp after moving and immediately fall.

[0067] Among them, the provision of the balance point can greatly save the experimental time. During the test process, a balance point for the animal to initially stand firm can be provided, avoiding the damage caused by the animal falling multiple times due to difficulty in getting familiar with the initial grasp, improving the safety of the experimental animals. Moreover, the balance point can be adjusted and withdrawn according to requirements, having the advantage of high flexibility in use, which is convenient for the test personnel to evaluate the animal's motor coordination ability.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
