Description

Technical Field

[0001] The utility model relates to the field of devices for animal experiments, in particular to a transfer cage for non-human primate experimental animals. Background Art

[0002] Non-human primate experimental animals are generally raised in animal rooms using experimental breeding cages. Generally, they need to be transferred at regular intervals. These transfer cages are usually designed to protect the safety and welfare of the animals, while being easy for researchers or keepers to operate to prevent animals from escaping from the cages. Sharp edges or protruding parts should be avoided to reduce the risk of injury to the animals.

[0003] However, most non-human primate experimental animal transfer cages currently have the following problems:

[0004] For example, the experimental animal transfer cage with publication number CN202222191308.1, although it can facilitate the transfer of experimental animals through the equipment, the equipment is mostly moved by universal wheels and pulleys during transportation. After moving to the location, the contact area between the universal wheels and the ground is small. If the equipment is affected by external force, it is easy to cause the equipment to shift, affecting the stability of the equipment. In addition, the height of the equipment is fixed. When the experimental animal needs to be taken out, it is necessary to bend down to grab it, which is inconvenient to operate and it is inconvenient to support and adjust the equipment conveniently. At the same time, the use space in the cage is in a stable state. When transferring multiple or different types of experimental animals, it is easy for the animals to hurt each other, affecting the subsequent experimental results, and it is inconvenient to separate the space in the cage for use.

[0005] Therefore, we made improvements on this and proposed a transfer cage for non-human primate experimental animals. Summary of the invention

[0006] The purpose of the utility model is to conveniently support and adjust the equipment in view of the current inconvenience and solve the problem.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Non-human primate experimental animals are transferred to cages to improve the above problems.

[0009] The specific application is as follows:

[0010] The control wheel is connected with the control wheel shaft through the support frame, and the control wheel shaft is connected with the control wheel shaft through the support frame.

[0011] As a preferred technical solution of the present application, the servo motor is fixedly connected to the center of one end of the bidirectional threaded rod, and the top surface of the moving block is in contact with the top surface inside the bottom plate.

[0012] As a preferred technical solution of the present application, the moving blocks are symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the moving blocks correspond one to one with the push plates.

[0013] As a preferred technical solution of the present application, the top end surface of the mesh plate is flush with the bottom end surface inside the transfer cage, and the cross-sections of the slider and the guide block are "T" shaped.

[0014] As a preferred technical solution of the present application, the guide blocks are symmetrically distributed on the left and right sides of the transfer cage, and the guide blocks correspond one-to-one with the connecting rods through limiting plates.

[0015] As a preferred technical solution of the present application, a pull plate is fixedly connected to the connecting rod, a clamping block is fixedly connected to the pull plate, and a side end face of the limit plate fits with an inner side face of the guide block.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. Through the bidirectional threaded rod, when supporting and adjusting the equipment, the servo motor on the bottom plate can be turned on, and the servo motor drives the bidirectional threaded rod to operate. When the bidirectional threaded rod rotates, it can drive the bidirectional threaded rods on both sides to rotate simultaneously through the transmission belt. When the bidirectional threaded rod rotates, it can drive the moving block to move. When the moving blocks on both sides move inward at the same time, the support plate can be pushed down by the push plate. After the support plate and the ground are supported, the friction between the equipment and the ground can be increased to avoid shaking and offset. When the support plate continues to move downward, the support plate can support the equipment and adjust the height so that it can be adjusted according to the usage.

[0019] 2. Through the provided partition, when adjusting and isolating the space in the transfer cage, the pull plates on both sides can be pulled, and the pull plates drive the limit plates to move through the connecting rods. When the limit plates move, they can squeeze the springs in the guide blocks, and at the same time, the pull plates can drive the card blocks to detach from the transfer cage. When the guide blocks are unobstructed, the guide blocks can be pushed to drive the partition plates to move, and at the same time, the partition plates can adjust and isolate the space in the transfer cage, which is convenient for separating according to the types of experimental animals. After the adjustment is completed, release the pull plates, and drive the limit plates to reset under the push of the springs. At the same time, the limit plates can drive the pull plates to reset through the connecting rods. When the pull plates are reset, they can drive the card blocks to engage in the transfer cage, and limit and fix the partition plates, which is convenient for adjusting the isolation space according to usage.

Example

[0032] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0033] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, the servo motor 2 is further fixedly connected to the center part of one end of the bidirectional threaded rod 3, and the top surface of the moving block 5 is in contact with the top surface inside the base plate 1, which can ensure that the moving block 5 can move smoothly through the support of the top surface inside the base plate 1 when moving.

[0034] like Figure 2 As shown, as a preferred implementation, on the basis of the above method, further, the moving blocks 5 are symmetrically distributed on the left and right sides of the bidirectional threaded rod 3, and the moving blocks 5 correspond to the push plates 6 one by one, which can ensure that the push plates 6 on both sides can simultaneously push the support plate 7 to move downward, thereby improving the stability of the movement of the support plate 7.

[0035] like Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the top end surface of the mesh plate 11 is flush with the bottom end surface inside the transfer cage 10, and the cross-section of the slider 12 and the guide block 16 is "T" shaped, which can ensure that the "T" shaped slider 12 and the guide block 16 can slide in a limited position in the transfer cage 10.

[0036] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the guide blocks 16 are symmetrically distributed on the left and right sides of the transfer cage 10, and the guide blocks 16 correspond one-to-one with the connecting rods 19 through the limiting plates 18, which can ensure the connection of the connecting rods 19 on both sides and can smoothly pull and move the pulling plate 20.

[0037] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, a pull plate 20 is fixedly connected to the connecting rod 19, and a clamping block 21 is fixedly connected to the pull plate 20. The side end face of the limit plate 18 fits with the inner side face of the guide block 16, which can ensure that the limit plate 18 can move smoothly through the support of the inner side face of the guide block 16 when moving.

[0038] Specifically, the non-human primate experimental animal transfer cage is used in combination with: Figure 1-5 When the experimental animals need to be transferred, the protective cover 13 on the transfer cage 10 can be opened. When the protective cover 13 moves, it can slide smoothly on the transfer cage 10 through the slider 12, and then the experimental animals can be stored in the transfer cage 10 on the connecting frame 8. If it is necessary to adjust and isolate the space in the transfer cage 10, the pull plates 20 on both sides can be pulled. The pull plates 20 drive the limit plates 18 to move through the connecting rods 19. When the limit plates 18 move, they can squeeze the spring 17 in the guide block 16, and at the same time, the pull plates 20 can drive the card block 21 to detach from the transfer cage 10. When the guide block 16 is unobstructed, the guide block 16 can be pushed to drive the partition 15 to move. At the same time, the partition 15 can adjust and isolate the space in the transfer cage 10, which is convenient for separating according to the types of experimental animals. After the adjustment is completed, the pull plate 20 is released, and the limit plate 18 is driven to reset under the push of the spring 17. At the same time, the limit plate 18 can drive the pull plate 20 to reset through the connecting rod 19. When the pull plate 20 is reset, it can drive the card block 21 to engage in the transfer cage 10, limit and fix the partition 15, and facilitate the adjustment of the isolation space according to the usage.

[0039] Then, when the equipment is pushed to move, it can be moved through the universal wheels on the bottom plate 1. During transportation or storage, the animal's feces can be discharged into the feces box 9 through the mesh plate 11, and the feces can be centrally processed. At the same time, the breathable net 14 on the protective cover 13 can play a ventilation role. The transfer cage 10 is surrounded to prevent the animal from being frightened by the outside world. After the equipment is moved to the operating position, when the equipment needs to be supported and adjusted, the servo motor 2 on the bottom plate 1 can be turned on, and the servo motor 2 drives the bidirectional threaded rod 3 to operate. When the bidirectional threaded rod 3 rotates, the transmission belt 4 can drive the bidirectional threaded rods 3 on both sides to rotate simultaneously. When the bidirectional threaded rod 3 rotates, it can drive the moving block 5 to move. When the moving blocks 5 on both sides move inward at the same time, the push plate 6 can push the support plate 7 to move downward. After the support plate 7 is supported by the ground, the friction between the equipment and the ground can be increased to avoid shaking and offset. When the support plate 7 continues to move downward, the support plate 7 can support the equipment and adjust its height so that it can be adjusted according to the usage.

[0040] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the utility model; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the utility model.
