[0029] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0030] It should be understood that experimental monkeys are usually kept in monkey houses with limited activity ranges. However, pregnant female monkeys have a need to increase their activity levels. If a larger cage is provided for them alone, it is not conducive to partition management and animal capture. Therefore, the present utility model proposes a through cage that can be connected to an existing monkey house to expand the activity range of pregnant female monkeys.

[0031]

Through cage

[0032] As shown in Figure 1 and Figure 2 the through cage proposed in the first aspect of the present utility model includes a first cage body 11, a second cage body 12, and a third cage body 13.

[0033] A first activity space is provided inside the first cage body 11, a second activity space is provided inside the second cage body 12, and a third activity space is provided inside the third cage body 13. The second cage body 12 is connected to the first cage body 11 and the third cage body 13, so that the first activity space, the second activity space, and the third activity space are interconnected.

[0034] This through cage is specifically connected to the monkey house of pregnant female monkeys. The pregnant female monkeys can freely enter and exit the through cage. Since the first activity space, the second activity space, and the third activity space in the through cage are interconnected, the pregnant female monkeys can obtain a sufficiently large activity space.

[0035] Furthermore, the first cage body 11 is used to connect to the cage body 21 of monkey house A, and the third cage body 13 is used to connect to the cage body 22 of monkey house B; a connecting structure 15 is provided on the first cage body 11, the second cage body 12, and / or the third cage body 13, and the connecting structure 15 is used to connect to the cage body 21 of monkey house A or the cage body 22 of monkey house B.

[0036] In this way, after the through cage and the original monkey house are connected together, the cage body 21 of monkey house A and the cage body 22 of monkey house B can be connected. If there is only one pregnant female monkey in the cage body 21 of monkey house A and the cage body 22 of monkey house B, the single female monkey can increase its activity space by 4 to 5 times. If there are two female monkeys in the cage body 21 of monkey house A and the cage body 22 of monkey house B, the two female monkeys can increase their activity space by 2 to 3 times.

[0037] Among them, both the first cage body 11 and the third cage body 13 are provided with windows 16. After the connecting structure 15 is connected to the A monkey house cage body 21 or the B monkey house cage body 22, the window 16 of the first cage body 11 corresponds to the door of the A monkey house cage body 21, and the window 16 of the third cage body 13 corresponds to the door of the B monkey house cage body 22.

[0038] In this way, by controlling the doors of the A monkey house cage body 21 or the B monkey house cage body 22, the activity area of the pregnant female monkey can be controlled.

[0039] In a preferred embodiment, the A monkey house cage body 21 and the B monkey house cage body 22 are arranged vertically up and down, the first cage body 11, the second cage body 12 and the third cage body 13 are distributed vertically, and the first cage body 11 is above the second cage body 12.

[0040] In this way, the living and exercise space of the pregnant female monkey can be significantly increased. During the vertical movement during pregnancy, if the amniotic fluid in the body is sufficient, the probability of the fetal head position can be significantly increased and the uterine contraction can be stimulated, so as to achieve the purpose of helping the animal to give birth naturally.

[0041] In an alternative embodiment, the connecting structure 15 is connected to the first cage body 11.

[0042] Preferably, the connecting structure 15 is a hook-shaped structure.

[0043] That is, the through cage 10 is connected to the breeding cage 20 through the hook-shaped structure provided at the top. Based on such a connection method, it is beneficial to mount and unmount the through cage 10 and maintain the structural stability after mounting.

[0044] In an alternative embodiment, a top rod is provided on one side of the first cage body 11, the second cage body 12 and / or the third cage body 13 facing the A monkey house cage body 21 or the B monkey house cage body 22, and the top rod is in contact with the A monkey house cage body 21 or the B monkey house cage body 22.

[0045] In this way, through the top rod provided on the cage body, support can be formed to maintain the stability of the through cage 10.

[0046] In an alternative embodiment, a fourth space 14 is provided at the bottom of the third cage body 13, and a manure collection drawer is placed in the fourth space 14. In this way, when the pregnant female monkey moves in the first cage body 11, the second cage body 12 or the third cage body 13, the feces generated can be collected by the manure collection drawer placed in the fourth space 14.

[0047] In the above embodiment, the first cage body 11, the second cage body 12 and the third cage body 13 all adopt the structural form of a stainless steel frame and a stainless steel mesh connected between the frames. The stainless steel material is corrosion-resistant and easy to clean, which is beneficial to maintaining the hygiene of the cage environment.

[0051] And the above-mentioned through cage 10;

[0052] Among them, monkey house cage body 21 of type A and monkey house cage body 22 of type B are arranged in the vertical direction.

[0053] It should be understood that the breeding cage includes multiple groups of cage bodies. Among them, monkey house cage body 21 of type A and monkey house cage body 22 of type B distributed vertically are taken as a group. According to needs, the user can specifically set the through cage 10 outside the cage where the pregnant female monkey is located to provide a larger activity space for the pregnant female monkey.

[0054] Further, both monkey house cage body 21 of type A and monkey house cage body 22 of type B are provided with cage doors, and the cage doors can be selected as sliding doors. The window 16 of the through cage 10 is recessed inward to facilitate the user to push the sliding door. It should be understood that the gap between the through cage 10 and the sliding door is not large enough for the female monkey to run out, but only facilitates the user to put their hand in.

[0055] Further, a feces collection space 23 for accommodating a feces collection drawer is provided at the bottom of both monkey house cage body 21 of type A and monkey house cage body 22 of type B. The feces collection drawer can be slid out or put into the feces collection space 23. In this way, no matter whether the female monkey moves in the through cage 10 or in monkey house cage body 21 of type A or monkey house cage body 22 of type B, the feces generated during this period can be effectively collected.

[0056] Combined with the above embodiments, the through cage proposed by the present utility model includes three cage bodies, the cage bodies are interconnected, and have two exits and a hook, which can connect the upper and lower layers of cage appliances and dock the cage doors of the upper and lower layers of cage appliances.
