Description
Technical Field
[0001] The utility model belongs to the technical field of animal running experiments, in particular to an anti-jamming component and an experimental animal running platform. Background Art
[0002] Currently, most animal treadmill experiments are conducted on rats or mice. The existing experimental animal treadmill has multiple running track grooves arranged horizontally in sequence (adjacent running grooves are separated by partitions), and a treadmill belt driven by a motor is set under the running grooves. However, there is a gap between the rear end of the treadmill belt and the back wall of the running groove (an electric shock device can be set in the gap to prevent the experimental animals from slacking off. At present, the electric shock device can also be removed to meet the ethical requirements of the experiment). If the experimental animals slack off on the treadmill belt, they will move backwards with the treadmill belt to the gap. At this time, the experimental animals are easily stuck in the gap, causing injury or death, which will affect the progress of the experiment. Utility Model Content
[0003] In order to solve the above technical problems, the purpose of the present invention is to provide an anti-stuck component with a simple structure that can be placed in a runway groove to cover the gap between the rear end of the treadmill and the rear wall of the runway groove and prevent experimental animals from being injured.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an anti-jamming component, including a ramp and hanging parts arranged on both sides of the ramp, the front side of the ramp is sloped, the ramp is used to be placed at the inner and rear ends of the runway groove, and the two hanging parts are used to be hung with the groove walls on both sides of the runway groove, and the front lower end of the ramp is located at the rear and upper part of the running belt.
[0005] The beneficial effect of the above technical solution is that the anti-jamming component can be placed at the inner rear end of the runway groove to cover the gap between the rear end of the treadmill belt and the inner wall of the rear end of the runway groove, and the slope of the ramp is facing forward. In this way, even if the experimental animal is moved backward by the treadmill belt due to laziness, it will only be sent to the slope of the ramp by the treadmill belt, and will not cause harm to the experimental animal.
[0006] The ramp described in the above technical solution includes two sub-slopes arranged along the left and right directions, and at least one of the sub-slopes is open on one side close to the other sub-slope. The two sub-slopes are plugged into each other and can slide relative to each other to adjust the width of the ramp. The two hanging parts are respectively arranged on the side of the two sub-slopes away from each other, and the front side of each sub-slope is sloped.
[0007] The beneficial effect of the above technical solution is that by setting the ramp as two plug-in sub-ramp platforms, the width of the ramp is adjustable so that it can meet the installation requirements of runway grooves of different widths.
[0008] The ramp platform in the above technical solution also includes an elastic member, which is arranged inside the ramp platform along the left and right directions, and its two ends are respectively connected to the two sub-slope platforms. The elastic force of the elastic member is used to drive the two sub-slope platforms to slide away from each other.
[0009] The beneficial effect of the above technical solution is that the two sub-ramp platforms are connected by an elastic member, and the elastic member also applies elastic force so that the two always tend to move away from each other. In this way, when the ramp platform is in the runway groove, its two sides always tend to fit with the inner walls of the runway groove on both sides (this can avoid the formation of a gap between the two to jam the limbs of the experimental animal).
[0010] The elastic member in the above technical solution is a spring or a damping rod.
[0011] The beneficial effect of the above technical solution is that it has a simple structure.
[0012] The slope of the front side of the ramp described in the above technical solution is 15-45°.
[0013] The beneficial effect of the above technical solution is that the slope of the ramp is made appropriate, and the experimental animals can be well transported to the slope of the ramp by the treadmill.
[0014] The above technical solution also includes an abutment rod arranged at the rear end of the ramp, which is horizontally arranged along the front and rear directions. The front end of the abutment rod is connected to the middle part of the rear end of the ramp, and the rear end of the abutment rod is used to abut against the inner wall of the rear end of the runway groove.
[0015] The beneficial effect of the above technical solution is that the volume of the ramp can be relatively reduced (mainly the length in the front-to-back direction is reduced).
[0016] In the above technical solution, the rear end of the abutting rod is provided with an enlarged portion.
[0017] The beneficial effect of the above technical solution is that the stability of the rear end of the contact rod when it contacts the inner wall of the rear end of the runway groove is better.
[0018] In the above technical solution, the front end of the abutment rod is provided with an external thread, and the rear end of the ramp is provided with a threaded hole. The front end of the abutment rod is threadedly connected to the threaded hole at the rear end of the ramp. The abutment rod is tightened or loosened to adjust the length of the abutment rod outside the ramp.
[0019] The beneficial effect of the above technical solution is that the extended length of the abutment rod can be adjusted as needed to adjust the front and rear position of the ramp in the runway groove.
[0020] In the above technical solution, a rolling member is embedded in the front lower end of the ramp, and the rolling member is used to support the rear upper end of the treadmill.
[0021] The beneficial effect of the above technical solution is that the front lower end of the ramp can be placed on the rear upper end of the treadmill without affecting the normal operation of the track groove.
[0022] The second purpose of the present utility model is to provide a laboratory animal treadmill with a simple structure and anti-stuck function, which can prevent the laboratory animals from getting stuck, getting injured or dying during the running experiment.
[0023] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an experimental animal treadmill includes the anti-jamming component as described above.
[0024] The beneficial effects of the above technical solution are: it has a simple structure and can prevent experimental animals from being injured or killed due to laziness and eventually getting stuck on the treadmill. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will be more clearly described according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in exact proportions. They are only used to facilitate and clearly illustrate the purpose of the embodiments of the present invention.
[0035] Example 1
[0036] like Figure 1 and Figure 2 As shown, this embodiment provides an anti-jamming component, including a ramp 11 and hanging components 12 arranged on both sides of the ramp 11, the front side of the ramp 11 is sloped, the ramp 11 is used to be placed at the inner and rear ends of the runway groove 21, and the two hanging components 12 are used to hang with the groove walls on both sides of the runway groove 21, the front lower end of the ramp 11 is located at the rear and upper part of the treadmill 22, so that the anti-jamming component can be placed at the inner and rear ends of the runway groove to cover the gap between the rear end of the treadmill and the inner wall of the rear end of the runway groove, and the slope of the ramp faces forward, so that even if the experimental animal is moved backward by the treadmill because of laziness, it will only be sent to the slope of the ramp by the treadmill, and will not cause harm to the experimental animal.
[0037] Specific as Figure 2 and Figure 3 As shown, the hanging member described in this embodiment can adopt a hook with the hook mouth facing downward and passing through from front to back, so that the groove walls on both sides of the runway groove can be inserted into the hanging member (the hanging member can be an inverted L-shape or an N-shape. When the hanging member is N-shaped, the horizontal height of its upper end is higher than the horizontal height of the upper end of the ramp).
[0038] The slope of the front side of the ramp 11 in the above technical solution is 15-45 degrees, which makes the slope of the ramp suitable and can well transport the experimental animals to the slope of the ramp by the treadmill.
[0039] In this embodiment, a rolling element 14 is embedded in the front lower end of the ramp 11. The rolling element 14 is used to support the rear upper end of the treadmill 22, so that the front lower end of the ramp can be placed on the rear upper end of the treadmill without affecting the normal operation of the runway groove. Specifically, a plurality of rolling elements can be arranged at intervals in the horizontal direction at the front lower end of the ramp. Preferably, two rolling elements can be arranged, and the two rolling elements are spaced apart in the left-right direction. In this embodiment, the rolling elements are balls or rollers (the axles of the rollers are distributed in the left-right direction), but their lower ends protrude from the bottom of the ramp, and the height of the protrusion is only 1-3 mm (this makes the front lower end of the ramp not in contact with the upper end of the treadmill but leaves only a small gap, which facilitates the transfer of the experimental animals to the slope of the ramp under the action of the treadmill).
[0040] Example 2
[0041] Same as Example 1, except that Figure 4 As shown, the ramp 11 in the above technical solution includes two sub-slopes 111 arranged in the left and right directions, and at least one of the sub-slopes 111 is open on one side close to the other sub-slope 111, and the two sub-slopes 111 are plugged into each other and can slide relative to each other to adjust the width of the ramp 11. The two hanging parts 12 are respectively arranged on the side of the two sub-slopes 111 away from each other, and the front side of each sub-slope 111 is sloped. By setting the ramp as two plug-in sub-slopes, the width of the ramp is adjustable so that it can meet the installation needs of runway grooves of different widths.
[0042] It should be noted that the elastic member in this embodiment will not squeeze the two sub-slopes apart from each other when deployed.
[0043] The ramp 11 in the above technical solution also includes an elastic member 112, which is arranged inside the ramp 11 along the left and right directions, and its two ends are respectively connected to the two sub-slopes 111. The elastic force of the elastic member 112 is used to drive the two sub-slopes 111 to slide away from each other, so that the two sub-slopes are connected by the elastic member, and at the same time, the elastic member also applies elastic force so that the two always tend to move away from each other. In this way, when the ramp is in the runway groove, its two sides always tend to fit with the inner walls of the runway groove on both sides (this can avoid the formation of a gap between the two to jam the limbs of the experimental animal).
[0044] The elastic member 112 in the above technical solution is a spring or a damping rod, and its structure is simple.
[0045] In this embodiment, a plurality of elastic members 112 may be provided in the ramp, and the plurality of elastic members are evenly distributed in the ramp.
[0046] Example 3
[0047] Same as Example 1, except that Figure 5 and Figure 6 As shown, the above technical solution also includes an abutment rod 13 arranged at the rear end of the ramp 11, and the abutment rod 13 is horizontally arranged along the front-to-back direction. The front end of the abutment rod 13 is connected to the middle part of the rear end of the ramp 11, and the rear end of the abutment rod 13 is used to abut against the inner wall of the rear end of the runway groove 21, so that the volume of the ramp can be relatively reduced (mainly the length in the front-to-back direction is reduced).
[0048] In the above technical solution, the rear end of the abutting rod 13 is provided with an enlarged portion 131, so that the stability of the rear end of the abutting rod when abutting against the inner wall of the rear end of the runway groove is better.
[0049] In the above technical solution, the front end of the abutment rod 13 is provided with an external thread, and the rear end of the ramp 11 is provided with a threaded hole 113. The front end of the abutment rod 13 is threadedly connected to the threaded hole 113 at the rear end of the ramp 11. The abutment rod 13 is tightened or loosened to adjust the length of the abutment rod 13 outside the ramp 11, so that the extended length of the abutment rod can be adjusted as needed to adjust the front and rear position of the ramp in the runway groove.
[0050] Example 4
[0051] like Figure 7 and Figure 8 As shown, this embodiment provides an experimental animal treadmill, including the anti-stuck component as described in Example 1, Example 2 or Example 3, which has a simple structure and can prevent experimental animals from being injured or killed due to laziness and eventually getting stuck on the treadmill.
[0052] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
