It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on this disclosure, those skilled in the art should understand that one aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number of aspects set forth herein can be used to implement a device and / or practice a method. Additionally, this device can be implemented and this method can be practiced using other structures and / or functionality in addition to one or more of the aspects set forth herein.
[0037] As an embodiment of the present utility model, as Figures 1 to 4 shown, there is provided an animal experiment device, comprising:
[0038] As Figure 3 and Figure 4 shown, an animal placement platform 1, a bracket assembly 2, and a base 3, wherein the animal placement platform 1 and the base 3 are respectively fixedly connected through two connection ends of the bracket assembly 2.
[0039] The bracket assembly 2 includes: a first triangular bracket 21, a second triangular bracket 22, and a central support rod 23.
[0040] All three support feet of the first triangular bracket 21 are connected to the base 3, and the top end of the first triangular bracket 21 is fixedly sleeved on the first connection point on the outer sidewall of the central support rod 23. All three support feet of the second triangular bracket 22 are connected to the base 3, and the top end of the second triangular bracket 22 is fixedly sleeved on the second connection point on the outer sidewall of the central support rod 23. The first connection point and the second connection point are located at different height positions on the central support rod 23. Any two corresponding support feet of the first triangular bracket 21 and the second triangular bracket 22 form the same angle between the two corresponding connection points on the base 3 and the center of the base 3. The degree of this angle can be an angle between 40° and 70°. One end of the central support rod 23 is connected to the animal placement platform 1.
[0041] By twisting two tripod structures by a certain angle and then connecting them between the base 3 and the central support rod 23, the connection stability can be further improved. The animal experiment device in this embodiment is a medical product, and the most important factor is to ensure stability, and the solution in this embodiment is more superior to the existing animal fixtures on the market in this regard.
[0042] Furthermore, as Figure 3As shown, the first triangular bracket 21 and the second triangular bracket 22 are both telescopic triangular brackets. For example, both the first triangular bracket 21 and the second triangular bracket 22 can be three-stage telescopic triangular brackets. The support feet of the first triangular bracket 21 and the second triangular bracket 22 are rotatably connected to the base 3 through spherical joints. The central support rod 23 is a multi-stage telescopic rod. The central support rod 23 is connected to the animal placement platform 1 through a spherical joint.
[0043] Through the above settings, both the central support rod 23 and the tripod itself can achieve three-stage telescoping. Thus, the overall height of the animal experiment device in this embodiment can be adjusted by telescoping. At the same time, the posture of the animal placement platform 1 can also be adjusted through the spherical joint connection for convenient experimental use.
[0044] In addition, both the first triangular bracket 21 and the second triangular bracket 22 are provided with strengthening arms. The strengthening arms include three connecting arms 24 and a connecting ring 25.
[0045] The three connecting arms 24 are respectively connected between the outer side wall of the connecting ring 25 and the three telescopic legs of the tripod. The connecting ring 25 is slidably sleeved on the outer side wall of the central support rod 23. By connecting the strengthening arms between the three legs of the triangular bracket and the central support rod 23, the stability of each tripod can be further improved.
[0046] Specifically, as Figure 4 shown, the base 3 is a circular base 3. A plurality of arm placement grooves 31 are opened near the edge of the bottom of the base 3. A corresponding expansion arm 32 is rotatably connected in each arm placement groove 31. Preferably, three arm placement grooves 31 are provided.
[0047] The base 3 can be made of a material with high-strength friction, which can increase the friction with the ground and ensure the stability of the base 3. At the same time, the edge of the base 3 is designed with expandable expansion arms 32. When they are opened, the force-bearing range of the entire base 3 can be increased, and the contact area with the ground can be increased, thereby achieving a more stable purpose. At the same time, adjusting screws are provided on each expansion arm 32, which can make it contact the ground more forcefully and even be fixed to the pre-reserved screw holes on the ground to increase stability. This structure is mainly designed to improve stability for occasions where high stability is required for animal experiments.
[0048] Specifically, as Figure 1 and Figure 2 shown, the animal placement platform 1 includes a first placement part 11, a second placement part 12, and a connecting rod 13.
[0049] Slides are provided inside both the first placement part 11 and the second placement part 12, and the connecting rod 13 is slidably inserted through the slides. In the bottom regions corresponding to the slides of the first placement part 11 and the second placement part 12 respectively, a plurality of fixing screw holes 14 are provided, and the fixing screw holes 14 penetrate from the bottoms of the first placement part 11 and the second placement part 12 to the inside of the slides. A plurality of Velcro straps 15 are also provided on the first placement part 11 and the second placement part 12.
[0050] The first placement part 11 and the second placement part 12 are used to hold different parts of the corresponding animal body. Therefore, their shapes need to be adapted to the corresponding animal body types. The animal placement platform 1 needs to be designed completely according to the ergonomic principle so that the animal can fit better on the device. Specifically, in this embodiment, the distance between the first placement part 11 and the second placement part 12 (the retracted part) can be adjusted, so that the length of the animal placement platform 1 can be adjusted to adapt to animals of different sizes. After the animal is placed on this fixture, the head, chest and legs of the animal are tied with the Velcro straps 15 to prevent the animal from moving. The fixing screw holes 14 of the entire placement platform adopt standard quarter screw interfaces, which can have better interchangeability and installation convenience to adapt to different animal types and experimental types.
[0051] In addition, in order to prevent the second placement part 12 from slipping off the connecting rod 13, a protrusion can be provided at the tail of the connecting rod 13 to limit the second placement part 12, and this protrusion structure can be a detachable structure such as a screw. At the same time, the tails of the first placement part 11 and the heads of the second placement part 12 are set to have an arc-shaped outer side surface. In this way, the range of the area where the first placement part 11 and the second placement part 12 can form a mutually fitting and squeezing area during the process of approaching each other can be reduced, and further, the risk of pinching the operator or the experimental animal caused by the gap between the first placement part 11 and the second placement part 12 can be reduced.
[0052] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
