The protection component 50 is arranged on the bottom wall of the support platform 10.

[0026] It should be noted that in this embodiment, the transfer component 30 limits the other set of transmission shafts 202, and the transfer component 30 moves up and down on the support platform 10. During the animal experiment, the protection component 50 is pulled out from the bottom wall of the support platform 10 to prevent the animal from directly falling to the ground during the experiment and protect the animal from being injured.

[0027] Specifically, the steps for testing the cardiopulmonary function of an animal are as follows: The driving component 201 is operated to drive the conveyor belt 203 to rotate through the transmission shaft rod 202. The animal is placed on the conveyor belt 203, and then the animal runs on the conveyor belt 203. During the running process, the baffle 204 prevents the animal from falling, and the transfer component 30 and the lifting and adjusting component 40 drive the conveyor belt 203 to adjust the inclination angle. The protection component 50 is pulled out from below the support platform 10 to prevent the animal from falling and protect the animal from being injured. It is convenient to test the cardiopulmonary function of the animal, and quickly adjust and protect the animal.

[0028] In an embodiment of the present invention, as Figure 1 shown, the transfer component 30 includes a fixed plate 301 and a connecting rod 302.

[0029] Among them, the fixed plate 301 is movably arranged on the support platform 10, and both ends of the connecting rod 302 are rotatably fixed to the fixed plate 301 and the support platform 10 respectively.

[0030] It should be noted that the fixed plate 301 is arranged directly above the support platform 10, and the connecting rod 302 is a double connecting rod. When the connecting rod 302 moves up and down on the fixed plate 301, the height of the fixed plate 301 is limited.

[0033] It should be noted that an inner groove is provided on the support platform 10, and the base 401 is movably disposed in the inner groove. The length of the movable wheel 403 is greater than the length of the baffle 204, so when the base 401 moves, the movable wheel 403 always abuts against the bottom wall of the baffle 204. The transmission component 404 is a transmission screw, and the transmission component 404 is threadedly connected to the base 401 when rotating, so as to drive the base 401 to reciprocate according to the direction in which the transmission component 404 rotates.

[0034] In one embodiment of the present invention, Figure 3 As shown, the protection assembly 50 includes a support frame 501 , a limiting slider 502 , a guide rod 503 , a limiting ring 504 and a protection net 505 .

[0035] There are two groups of support frames 501, one group of support frames 501 is arranged on the bottom wall of the support platform 10, and the limit slider 502 is arranged on the top wall of the other group of support frames 501, and the limit slider 502 is movably arranged on the bottom wall of the support platform 10. One end of the guide rod 503 is arranged on the limit slider 502, and the limit ring 504 is arranged on the top wall of one group of support frames 501, and the other end of the guide rod 503 passes through the limit ring 504, and the protective net 505 is arranged between the two groups of support frames 501.

[0036] It should be noted that the support frame 501 is moved and adjusted on the bottom wall of the support platform 10 by the limit slider 502, so that the two groups of support frames 501 are separated, and the protective net 505 is opened and located below the conveyor belt 203. When the animal slides down, it falls into the protective net 505 to avoid falling directly on the ground and getting injured.

[0037] Furthermore, the protective net 505 is snap-fitted to the support frame 501 , so when an animal falls into the protective net 505 , the protective net 505 can be easily removed to move the animal to the animal rest room without the operator having to manually grab the animal.

[0039] It should be noted that a limiting sliding groove is provided on the bottom wall of the support platform 10 , and the limiting slider 502 slides in a limited manner in the limiting sliding groove, thereby facilitating the limited sliding adjustment on the bottom wall of the support platform 10 .

[0040] Specifically, the steps of testing the cardiopulmonary function of animals through the experimental treadmill are as follows: the driving component 201 drives the conveyor 203 to rotate through the transmission shaft 202, and the animal is placed on the conveyor belt 203, so that the animal runs on the conveyor belt 203, and the baffle 204 prevents the animal from falling during the running process. The conveyor belt 203 is driven to adjust the tilt angle through the adapter component 30 and the lifting adjustment component 40, and the transmission component 404 is threadedly connected with the base 401 during rotation, so as to drive the base 401 to move back and forth according to the rotation direction of the transmission component 404, and then the movable wheel 403 moves synchronously with the base 401, and the movable wheel 403 is engaged with the baffle 204 to control the tilt angle of the conveyor belt 203. Pull out the protection component 50 from the bottom of the support platform 10, pull a group of movable support frames 501, and slide on the bottom wall of the support platform 10 through the limit slider 502. The guide rod 503 is limited in the limiting ring 504, so that the protective net 505 is stretched open, and when the animal falls, it falls into the protective net 505, preventing the animal from falling and protecting the animal from injury. It is convenient to test the cardiopulmonary function of the animal, and quickly adjust and protect the animal.

[0041] In summary, the experimental treadmill based on animal cardiopulmonary function test in the embodiment of the utility model adopts a rolling cooperation method. While pushing and adjusting the inclination angle of the conveyor belt, it does not affect the continuity and accuracy of the experiment. At the same time, the protective net effectively protects the animals and facilitates the capture of the experimental animals.
