Description

Technical Field

[0001] This utility model relates to the field of animal experimental equipment technology, and in particular to an animal experimental running platform with an adjustable slope. Background Technology

[0002] The treadmill test is a widely used experimental method in biomedical research, primarily used to assess animal locomotion, study the effects of exercise on physiological functions, and explore the mechanisms of movement-related diseases. This method is widely adopted because it can simulate movement in natural environments.

[0003] Designing slope adjustment functions in animal experimental treadmills has significant scientific value and experimental purposes, such as simulating diverse natural movement scenarios to improve ecological validity; finely regulating exercise load and metabolic demands; and constructing key phenotypes in disease models. For example, in constructing key phenotypes for disease models, slope sensitivity can be used as an early indicator: PD model mice exhibit gait freeze at a small slope of 5°, while normal mice are unaffected. Similarly, in skeletal muscle diseases, such as weakness of the exposed muscles on uphill slopes, diseased mice cannot maintain speed at a slope of 10°, exhibiting symptoms earlier than on flat ground.

[0004] Based on the above reasons, this utility model designs an adjustable slope animal experimental treadmill, which can precisely adjust the slope of the treadmill. Utility Model Content

The sliding grooves at the bottom of the rotating blocks on both sides of the treadmill base are driven by a rotary drive mechanism to slide and rotate in cooperation with the upper surface of the rotating seat, thereby realizing the adjustment of the slope of the treadmill base. By setting angle scale lines on the front wall of the rotating seat and the pointer on the outer wall of the rotating block, the slope of the treadmill base can be adjusted more accurately, so as to precisely adjust the treadmill base to a suitable slope according to different experimental needs.

Detailed Implementation

[0024] The present invention will be further described below:

[0025] Please see Figure 1-7 ,

[0026] This utility model discloses an adjustable slope animal experimental treadmill, including a treadmill base 1, rotating blocks 2, rotating seats 3, and a rotation drive mechanism 4. The treadmill base 1 has a square structure with a square groove 5 on its top. A treadmill 6 is located below the inner wall of the groove 5. The treadmill 6 is a prior art structure, consisting of a rotatable pulley and a conveyor belt. The top of several treadmills 6 is divided into several tracks 8 by partitions 7. Dividing the top of the treadmills 6 into several tracks 8 by partitions 7 allows multiple animals to be tested simultaneously, making the experimental results more accurate. Two square rotating blocks 2 are fixed to both sides of the treadmill base 1. The bottom of each rotating block 2 has an arc-shaped groove 9. Two rotating seats 3 have a semi-circular structure, with the bottom of each rotating seat 3 fixed to the outside. The bottom groove 9 can slide in cooperation with the upper surface of the rotating seat 3. The front wall of the rotating seat 3 is provided with an angle scale line 15. The lower part of the outer wall of the rotating block 2 is provided with a pointer 16 for pointing to the angle scale line 15. The bottom of the treadmill base 1 and the two rotating seats 3 are provided with a rotation drive mechanism 4 for driving the treadmill base 1 to rotate. In this utility model, the bottom groove 9 of the rotating blocks 2 on both sides of the treadmill base 1 can slide and rotate in cooperation with the upper surface of the rotating seat 3 through the rotation drive mechanism 4, thereby realizing the adjustment of the slope of the treadmill base 1. By setting the angle scale line 15 on the front wall of the rotating seat 3 in cooperation with the pointer 16 on the outer wall of the rotating block 2, the slope of the treadmill base 1 can be adjusted more accurately, so as to precisely adjust the treadmill base 1 to a suitable slope according to different experimental requirements.

[0027] Furthermore, the lower surface of the slide groove 9 is connected to the top of the limiting bolt 11 at its center; the front wall of the rotating seat 3 is a semi-circular limiting groove 10, and the top of the limiting groove 10 forms a limiting semi-circular ring 12. The top of the limiting semi-circular ring 12 is provided with a bolt groove 13 for the sliding of the limiting bolt 11. The bottom end of the limiting bolt 11 passes through the bolt groove 13 and is threadedly connected to the limiting nut 14. The limiting bolt 11 can slide along the limiting groove 10 and then be limited by the limiting nut 14, which can ensure that the slide groove 9 at the bottom of the rotating block 2 can stably slide with the top of the rotating seat 3 under the drive of the rotating drive mechanism 4; and after the slope of the running platform base 1 is adjusted, the limiting nut 14 can be used in conjunction with the limiting bolt 11 to lock the rotating block 2 and the rotating seat 3, preventing rotation during the experiment.

[0028] Furthermore, the angle scale line 15 is set on the front wall of the limiting semicircular ring 12. By setting the angle scale line 15 and the pointer 16, the slope of the running platform base 1 can be precisely adjusted.

[0029] Furthermore, a square washer 17 is provided above the limiting nut 14. The square washer 17 has a washer hole in the middle for fitting onto the outside of the limiting bolt 11. The square washer 17 is a square structure with a rounded top. By setting the square washer 17, the running platform base 1 can be better locked by the limiting nut 14 after being adjusted to a suitable angle. A mounting plate 18 is provided between the bottom of the inner walls on both sides of the limiting semicircular ring 12, which is arranged horizontally. The mounting plate 18 has a mounting hole in the middle. By setting the mounting plate 18 and the mounting hole, it is convenient to fix the rotating seat 3 to an external mounting seat or other places.

[0030] Furthermore, the rotary drive mechanism 4 includes a worm gear 41, a worm wheel 42, a bearing 43, a motor 44, and a connecting block 45. The connecting block 45 is a semi-circular structure fixed between the inner walls of the two rotating seats 3 on both sides, and the bottom of the connecting block 45 is flush with the bottom of the rotating seat 3. The worm wheel 42 is a semi-circular structure with a semi-circular groove in the middle of its bottom for connecting with the upper surface of the connecting block 45. The upper surface of the worm wheel 42 has teeth that mesh with the worm gear 41. The bottom of the running platform base 1 has a semi-circular bearing connecting groove 46. The outer ends of the worm wheel 42 are fixedly connected to the inner rings of the two bearings 43, and the outer walls of the bearings 43 are flush with the inner rings of the two bearings 43. The inner wall of the bearing connecting groove 46 is connected, and the outer diameter of the bearing 43 is larger than the outer diameter of the worm gear 42. The motor 44 has a circular structure, and its outer wall is connected to the inner wall of one end of the bearing connecting groove 46. The output end of the motor 44 is connected to one end of the worm 41. The working process of the rotary drive mechanism 4 is as follows: When it is necessary to adjust the slope of the treadmill base 1, the motor 44 is turned on, and the output end of the motor 44 drives the worm 41 to rotate. Since the outer wall of the worm 41 meshes with the teeth of the worm gear 42, and the worm gear 42 is fixed, the worm 41 can rotate along the upper surface of the worm gear 42, thereby driving the treadmill base 1 to rotate. The slope of the treadmill base 1 is adjusted in the experiment.

[0031] Furthermore, a gap is provided between one end of the treadmill 6 and the inner wall of the groove 5, and several electrical stimulation rods 19 are connected at intervals on the inner wall of the gap. By setting the electrical stimulation rods 19, the changes in the animal's movement behavior on the treadmill can be observed, and the control mechanism of specific neural circuits on movement can be analyzed.

[0032] Furthermore, a transparent cover plate 20 is provided on the top of the treadmill base 1, and cover plate limiting plates 21 are provided on both sides of the top of the treadmill base 1 along its length direction. By setting the transparent cover plate 20 made of transparent material to cover the top of the treadmill base 1, the experimental condition of the animal can be observed while ensuring that the animal will not jump out of the treadmill base 1. The cover plate limiting plates 21 can play a limiting role, making it easier for the transparent cover plate 20 to cover the top of the treadmill base 1.

[0033] Furthermore, the transparent cover plate 20 includes an inlet cover plate 22, a middle cover plate 23, and an outlet cover plate 24. The inlet cover plate 22 is located above the electrical stimulation rod 19. The inner end of the inlet cover plate 22 is hinged to one end of the middle cover plate 23 via a hinge 25. The other end of the middle cover plate 23 is hinged to the inner end of the outlet cover plate 24 via a hinge 25. The inlet cover plate 22 and the outlet cover plate 24 are respectively hinged to both ends of the middle cover plate 23 via hinges 25, which facilitates opening the inlet cover plate 22 to put in the animal during the experiment and opening the outlet cover plate 24 to take out the animal at the end of the experiment.
