Description

Technical Field

[0001] This utility model belongs to the field of animal cage technology, specifically relating to an IVC cage with adjustable feeding space. Background Technology

[0002] Laboratory animal cages are widely used in animal experiments at major research institutions, universities, and manufacturing companies both domestically and internationally. Depending on the research objective, the requirements for laboratory animal cages vary. In animal experiments, it is essential to ensure that the animals have sufficient space to move around within the cage. However, when the space within the cage is large enough for the animals to move around, if observation or procedures such as blood collection or injection are required, the animals will run around wildly within the cage, becoming difficult to control. This can also cause the animals to be easily frightened, panicked, and subsequently resist or injure people, with potentially disastrous consequences.

[0003] Therefore, there is a need for cages that are more functional, make animals more comfortable, and facilitate observation or treatment of animals (such as injection, blood collection, and sampling). Utility Model Content

[0004] This invention provides an IVC cage with adjustable rearing space, which solves the problem that existing animal cages, when the space inside is sufficient for animal movement, make it inconvenient to observe or handle the animals.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an IVC cage with adjustable rearing space, comprising: A feeding assembly, comprising a tray, a drain hole penetrating the tray, a feeding box fixed to the top of the tray, and a partition movably installed inside the feeding box, the partition dividing the interior of the feeding box into a feeding chamber and an adjustment chamber; The excretion assembly includes an excretion box fixed to the bottom of the tray, an excretion groove opened on the top of the excretion box and communicating with the excretion hole, and a collection box inserted into the excretion groove.

[0006] Ideally, the feeding box includes a third side plate fixed to the top of the tray and spaced apart, a top plate fixed to the top of the third side plate, and a cage door slidably connected to both sides of the third side plate.

[0007] Optimally, the feeding assembly further includes an upper slot formed on the top of the tray, a lower slot formed on the bottom of the top plate, a lower plate fixed to the bottom of the cage door and cooperating with the upper slot, and an upper plate fixed to the top of the cage door and cooperating with the lower slot.

[0008] Optimally, the feeding assembly further includes an extension plate fixed to the side of the partition near the feeding chamber and a push plate fixed to the opposite side of the extension plate.

[0009] Optimally, the feeding assembly further includes through holes that penetrate the third side plate and are spaced apart, insertion holes that are formed on both sides of the partition plate and cooperate with the through holes, and pins that pass through the through holes and the insertion holes.

[0010] Optimally, the feeding assembly also includes a locking post fixed to one side of the third side plate, a locking plate rotatably mounted on the outside of the cage door, and a locking groove and a through groove formed on one side of the locking plate and communicating with each other.

[0011] Optimally, the feeding assembly further includes a support plate fixed to one side of the cage door for supporting the locking plate, and an arc-shaped portion disposed on the side of the locking plate near the locking post.

[0012] Ideally, the diameter of the locking groove is larger than the diameter of the locking pin.

[0013] Optimally, the feeding assembly further includes a slide rail fixed to the inner side of the tray and the top plate, and a slider slidably mounted on the slide rail, with the partition fixed to the slider.

[0014] Optimally, the excretion box includes a first side plate fixed to the bottom of the tray and spaced apart, a bottom plate fixed to the bottom of the first side plate, and a second side plate fixed to one side of the first side plate, and the excretion groove is formed between the first side plate, the second side plate and the bottom plate.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to an IVC cage with adjustable rearing space. By dividing the cage into a rearing chamber and an adjustment chamber by a partition, the size of the rearing chamber can be adjusted by changing the position of the partition. When rearing, the rearing chamber is adjusted to its maximum size. When it is necessary to observe or treat the laboratory mice (such as injection, blood collection, sampling, etc.), the partition is pushed to reduce the size of the rearing chamber, preventing the laboratory mice from running around and making it easier for the rearer to operate.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] like Figure 1-3 The diagram shows an IVC cage with adjustable rearing space according to the present invention. The cage consists of two parts: a lower excretion component and an upper rearing component. The rearing component is used to raise laboratory mice, and the excretion component is used to collect the excrement produced by the laboratory mice in their daily lives, so as to avoid the excrement remaining in the rearing chamber 15 for a long time and affecting the living environment of the laboratory mice.

[0019] The base plate 1 is a rectangular plate with two sets of long sides and two sets of short sides arranged opposite each other. There are two first side plates 2, which are vertically fixed to the top of the base plate 1 and spaced apart (specifically, the first side plates 2 are fixed to the top of the two long sides of the base plate 1). There is one second side plate 3, which is vertically fixed to the top of the base plate 1 (specifically, the second side plate 3 is fixed to the same side of the two first side plates 2). The base plate 1, the first side plates 2, and the second side plates 3 form a drainage trough, and a collection box 6 is inserted into the drainage trough to collect the excrement of the experimental mice above.

[0020] The tray 4 is fixed to the top of the first side plate 2 and the second side plate 3 to support the feeding components above. The excretion holes 5 extend vertically through the tray 4 and are spaced apart. The excrement produced by the laboratory mice falls into the collection box 6 below through the excretion holes 5. The keepers can periodically remove the collection box 6 for cleaning.

[0021] There are two third side panels 7, which are vertically fixed to the top of the tray 4 and spaced apart. The third side panels 7 are located on the two long sides of the tray 4. The top plate 8 is fixed to the top of the two third side panels 7. The top plate 8 and the interior of the two third side panels 7 enclose the feeding space. The partition 14 is movably installed inside the two third side panels 7 and divides the space inside the feeding box into a feeding cavity 15 and an adjustment cavity 16. By adjusting the position of the partition 14, the size of the feeding cavity 15 can be adjusted.

[0022] There are two cage doors 11, which are installed on both sides of the third side plate 7 to block the feeding chamber 15 and the adjustment chamber 16. The upper slot 9 is opened on the top of the support plate 4 and is spaced apart. The upper slot 9 is parallel to the wide side of the support plate 4. The lower slot 10 is opened on the bottom of the top plate 8 and is spaced apart. The lower slot 10 is positioned opposite the upper slot 9, that is, the lower slot 10 is located directly above the upper slot 9.

[0023] The lower locking plate 13 is fixed to the bottom of the cage door 11 and cooperates with the upper locking groove 9, while the upper locking plate 12 is fixed to the top of the cage door 11 and cooperates with the lower locking groove 10. By setting the mutually cooperating lower locking plate 13 and upper locking groove 9, as well as upper locking plate 12 and lower locking groove 10, sliding the cage door 11 is more effortless and convenient.

[0024] like Figure 5 As shown, a locking mechanism is provided between the cage door 11 and the third side plate 7 to lock the cage door 11. The locking mechanism includes a locking plate 24, a support plate 25, a locking pin 26, an arc-shaped part 27, a locking groove 28, and a through groove 29. The locking plate 24 is rotatably mounted on the outside of the cage door 11 via a pin, and the locking pin 26 is fixed to the outside of the third side plate 7. The locking plate 24 has an interconnected locking groove 28 and a through groove 29 on the side near the locking pin 26. The locking groove 28 is semi-circular, and its diameter is equal to the width of the through groove 29.

[0025] like Figure 5 As shown, the locking groove 28 and the through groove 29 form a "U" shape, and the diameter of the locking groove 28 is larger than the diameter of the locking pin 26, so that the locking plate 24 avoids movement interference with the locking pin 26 when it rotates. The arc-shaped part 27 is provided on the side of the locking plate 24 near the locking pin 26. By providing the arc-shaped part 27, the locking plate 24 is pushed to flip and lock onto the locking pin 26. The support plate 25 is fixed to one side of the cage door 11 and is used to support the locking plate 24. Otherwise, the locking plate 24 cannot remain horizontal under the action of gravity (the support plate 25 and the locking plate 24 are not fixed together, but only in contact with each other).

[0026] The locking principle of the locking mechanism is as follows: Under the support of the support plate 25, the locking plate 24 is in a horizontal state. When the cage door 11 needs to be closed, the breeder holds the handle on one side of the cage door 11 and pulls the cage door 11 towards the locking post 26. When the arc-shaped part 27 of the locking plate 24 contacts the locking post 26, the locking post 26 will push against the arc-shaped part 27 until the locking plate 24 rotates counterclockwise. When the through groove 29 passes the locking post 26, the locking plate 24 falls down. At this time, the through groove 29 and the locking groove 28 are locked on the locking post 26 to complete the locking of the cage door 11. When the cage door 11 needs to be opened, the breeder lifts the locking plate 24 to release the lock and then pulls the cage door 11 to the other side.

[0027] like Figure 4 , 6 As shown, the partition 14 is movably installed inside the two third side plates 7, dividing the space inside the feeding box into a feeding chamber 15 and an adjustment chamber 16. By adjusting the position of the partition 14, the size of the feeding chamber 15 can be adjusted. The slide rail 20 is fixed to the top of the tray 4 and the bottom of the top plate 8 by screws, and the slide rail 20 is close to the third side plate 7. The slider 21 is slidably installed on the slide rail 20, and the partition 14 is fixed to the top of the slider 21. Through the cooperation of the slide rail 20 and the slider 21, it is convenient for the breeder to push the partition 14.

[0028] like Figure 4 As shown, the extension plate 22 is fixed to one side of the partition 14 and located within the feeding area, while the push plate 23 is fixed to the side of the extension plate 22 away from the partition 14, forming an "L" shape with the extension plate 22. When the zookeeper pushes the partition 14 to reduce the space of the feeding area, to prevent the slider 21 from accidentally trapping the fur of the experimental mice as it moves along the slide rail 20, the extension plate 22 and the push plate 23 separate the experimental mice within the feeding area, keeping the mice's fur away from the connection between the slide rail 20 and the slider 21.

[0029] like Figure 6 As shown, through holes 17 extend horizontally through the third side plate 7 and are spaced apart. Insertion holes 18 are opened on the outside of the partition 14 and cooperate with the through holes 17. Pins 19 are inserted into the through holes 17 and the insertion holes 18 to limit the partition 14. By opening multiple sets of through holes 17 arranged side by side on the third side plate 7, the limiting of the partition 14 at different positions can be satisfied.

[0030] By setting cage doors 11 on both sides of the feeding box, the feeding box can be opened from both sides. One side is used to take out and put in the experimental mice, and the other side is used to push the partition 14 from the inside to adjust the space of the feeding chamber 15.

[0031] The cage is divided into a feeding chamber 15 and an adjustment chamber 16 by a partition 14. The size of the feeding chamber 15 can be adjusted by adjusting the position of the partition 14. When feeding, the space of the feeding chamber 15 is adjusted to the maximum and limited by a pin 19. When it is necessary to observe or treat the experimental mice (such as injection, blood collection, sampling, etc.), the partition 14 is pushed to reduce the space of the feeding chamber 15 to prevent the experimental mice from running around and to facilitate the operation of the breeder.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
