Therefore, it is particularly necessary to improve the existing structure of rotating rod. Although the current rotating rod design meets the basic needs of the experiment to some extent, its limitations are increasingly prominent when dealing with diversified and complex motion states of animals. The fixed rotating rod style and single structure design make it difficult for animals to quickly and accurately adjust their body posture in rapid turning, immediate balance adjustment after jumping landing and other actions, which greatly limits the improvement of animal motor coordination and accurate balance perception, and also affects their endurance performance under long-time activity. More importantly, the design of the rotating rod surface does not fully consider the effective stimulation of animal foot receptors, resulting in a lack of sufficient immediate feedback information for animals when maintaining balance, which not only affects the training effect, but also may have adverse effects on the development of animal motor ability and balance perception ability. Therefore, in order to better meet the experimental requirements and improve the motor ability and balance perception of animals, it is particularly important to improve and optimize the existing structure of rotating rod.

DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Referring to the drawings Figures 1-2 ;

[0026] A composite rotating fatigue tester includes a fatigue tester body 1. The test area 3 is divided into multiple channels 3 by a partition plate 2. Each partition plate 2 has a through hole. A rotating rod 4, which passes through each through hole, is horizontally mounted on the fatigue tester body 1. A detachable sleeve wheel 5 is fitted onto the rotating rod 4. The sleeve wheel 5 has a structure designed to increase the animal's coordination, balance, and endurance difficulty. The sleeve wheel 5 includes two sets of interlocking semi-cylindrical frames 51. The middle portion of each semi-cylindrical frame 51 has a slot 52 for engaging with the rotating rod 4. Interlocking components are installed on the mating surfaces of the semi-cylindrical frames on both sides of the slot 52. By designing the sleeve wheel as two sets of interlocking semi-cylindrical frames, it can be easily installed on the rotating rod. This design makes the installation process simpler and faster, and also facilitates subsequent disassembly and maintenance. The interlocking components, installed on the mating surfaces of the semi-cylindrical frames, ensure that the two sets of semi-cylindrical frames fit tightly together when connected, forming a stable structure.

[0027] The semi-cylindrical frame 51 can be a solid or hollow structure, and these structures can be combined and fitted onto rotating rods 4 in different channels. The mating fastening assembly includes magnets that attract each other, or slots and clips for mating and fastening, or connecting screws.

[0028] Furthermore, the semi-cylindrical frame 51 is a solid structure with textured surfaces on its outer circumferential surface. The solid semi-cylindrical frame 51 is injection-molded from plastic, and its surface has serrated edges 5111. Corresponding mounting slots 5112 are provided on the mating surfaces on both sides of the central slot. Magnets 5113, with mutually attracting poles, are installed on the mounting slots 5112 of the two mating semi-cylindrical supports. The textured design not only improves the overall strength of the wheel but also ensures stable support for the animal during movement. The special surface structure of the wheel, such as textures and protrusions, enhances the animal's foot perception during movement, promotes muscle memory formation, and thus improves motor coordination. Simultaneously, the optimized contact area and distribution help distribute the pressure on the animal's feet, reducing the burden on the feet during prolonged training. The stability and comfort of the wheel structure help animals achieve more complex movement states in experiments, thereby improving the accuracy and breadth of experimental data.

[0029] Furthermore, the semi-cylindrical frame 51 has a hollow structure, including two end plates 5121. The middle portion of each end plate 5121 has a groove 5122, and connecting plates 5123 are provided on both sides of the grooves 5122 to connect and fix the end plates 5121, forming the semi-cylindrical frame. The circumference of each end plate 5121 has spaced and corresponding insertion holes 5125, into which insertion rods 5124 are inserted. This hollow structure improves movement efficiency in jumping experiments, allowing the test subject to more easily complete complex jumping movements. It also increases the flexibility of the structure, enabling the test subject to better adapt to different ground conditions and movement requirements during jumping. The insertion rods 5124 can be inserted and removed as needed according to the spacing of the hollow structure. The connecting plates 5123 of the hollow semi-cylindrical frame have corresponding threaded holes 5126, which are fixed by screws.

[0030] The above structure is used as follows:

[0031] (1) Installation of the sleeve: Before the experiment, first install the sleeve with the above structure onto the rotating rod as needed. Solid structure and hollow structure sleeves are selected according to the experimental needs and can be installed at intervals on different channels.

[0032] (2) Animal placement: Hold the experimental animal and place it on the rotating bar, usually facing away from the direction of rotation. Begin the experiment after ensuring the animal is stable.

[0033] (3) Start the equipment: Start the motor and timer. The rotating rod starts to rotate according to the preset parameters. When setting the parameters, ensure that the rotating rod starts to rotate at a relatively slow speed. The animal needs to constantly adjust its body posture to maintain balance. Speed ​​adjustment and balance challenge: As the experiment progresses, the speed of the rotating rod will gradually increase to increase the difficulty for the animal to maintain balance. The animal needs to continuously adjust its body posture on the constantly accelerating rotating rod to maintain balance.

[0034] (4) Observation, recording, fall detection and data recording: Observe the animal’s walking on the rotating bar, record the latency period of the animal falling off the rotating bar, i.e. the time from when it is placed on the rotating bar to when it falls off the bar, the speed of the fall, the walking distance and other data. At the same time, pay attention to recording the animal’s behavior, such as posture, coordination and adaptability.

[0035] When an animal falls off the rotating bar due to fatigue or loss of balance, the instrument will automatically stop timing and record the fall time. Fall time is an important indicator for assessing an animal's motor performance, reflecting its motor coordination, balance, and endurance.

[0036] (5) Repeated experiments: In order to obtain more reliable data, it is usually necessary to repeat the experiment multiple times and take the average value as the final result.

[0037] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0038] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
