Description

Technical Field

[0001] The utility model relates to an experimental animal breeding device, in particular to an experimental animal transfer device. Background Art

[0002] The experimental animal transfer device is a container for temporarily placing experimental animals during transportation and transfer. Its main function is to restrict the movement of experimental animals, prevent the escape of experimental animals, and complete the transportation and transfer of experimental animals between different locations.

[0003] The existing experimental animal group cages and experimental animal transfer devices are independent of each other. When the experimental animals in the group cages need to be transferred to single cages for breeding, the experimental animals need to be caught. The whole process causes great stress to the experimental animals, is difficult to catch, and there is a risk of injury to the operators. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a laboratory animal transfer device to effectively reduce the stress response of the laboratory animals, and does not require manual grasping, thereby avoiding the risk of injury to operators.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] The utility model provides an experimental animal transfer device, which is characterized by comprising a transition cage and a transfer cage; the transition cage is fixedly arranged between adjacent side wall structures of two group cages, and the side wall structure of the group cage is provided with a transfer channel connected with the internal space of the transition cage; first vertical sliding doors that can block the transfer channel on the same side are respectively arranged on both sides of the transition cage, and a second vertical sliding door is arranged at the front end; third vertical sliding doors are respectively arranged at the front end and the rear end of the transfer cage; and a linking mechanism is arranged between the transition cage and the transfer cage.

[0007] The linking mechanism comprises fixed ear plates fixedly arranged at two corners of the top structure of the transition cage, and linking ear plates fixedly arranged at four corners of the top structure of the transfer cage, and through holes for the pins to pass through are opened on the plate surfaces of the fixed ear plates and the linking ear plates.

[0008] The beneficial effect of the utility model is that a transition cage is arranged on the side of the group cage, and the transfer cage is connected to the transition cage through a link mechanism. By switching the vertical sliding doors between the group cage, the transition cage and the transfer cage and luring food, the experimental animals in the group cage are transferred to the transition cage and the transfer cage in turn, and then transferred to the experimental area by the transfer cage. The whole process does not require manual grasping, which can effectively reduce the stress response of the animals and avoid the risk of injury to the operators. In addition, some simple experimental operations can be performed on the experimental animals directly in the transfer cage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Reference Figure 5 The experimental animal transfer device of the utility model comprises a transition cage 20 and a transfer cage 30. Figure 1 and Figure 2 The transition cage 20 is fixedly arranged between the adjacent side wall structures of the two group cages 10, and the side wall structure of the group cage 10 has a transfer channel A connected to the internal space of the transition cage 20. The first vertical sliding door 11 that can block the transfer channel A on the same side is respectively arranged on both sides of the transition cage 20, and the second vertical sliding door 21 is arranged at the front end. Figure 3 and Figure 4 The front end and the rear end of the transfer cage 30 are respectively provided with a third vertical sliding door 31. A link mechanism is provided between the transfer cage 20 and the transfer cage 30.

[0018] Reference Figure 5The utility model sets a transition cage 20 on the side of the group cage 10, and the transfer cage 30 is connected to the transition cage 20 through a link mechanism. Through the switching of the first vertical sliding door 11 between the group cage 10 and the transition cage 20, and the second vertical sliding door 21 and the third vertical sliding door 31 between the transition cage 20 and the transfer cage 30 and the lure of food, the experimental animals in the group cage 10 are transferred to the transition cage 20 and the transfer cage 30 in turn, and then transferred to the experimental area by the transfer cage 30. The whole process does not require manual grasping, which can effectively reduce the stress response of animals and avoid the risk of injury to operators. In addition, some simple experimental operations can be performed on the experimental animals directly in the transfer cage.

[0019] Reference Figure 2 and Figure 4 The linking mechanism includes fixed ear plates 22 fixedly arranged at two corners of the top structure of the transition cage 20, and linking ear plates 32 fixedly arranged at four corners of the top structure of the transfer cage 30. Through holes for the pins to pass through are opened on the surfaces of the fixed ear plates 22 and the linking ear plates 32.

[0020] Reference Figure 2 In order to avoid the vertical sliding doors from being opened by mistake, a spring buckle 40 is fixedly provided on the top structure of the transition cage 20, which acts on the first vertical sliding door 11 and the second vertical sliding door 21 respectively. Figure 4 The top structure of the transfer cage 30 is covered with a transparent plate 33 and is provided with a spring buckle 40 that acts on the third vertical sliding door 31 .

[0021] Reference Figure 3 The two third vertical sliding doors 31 on the transfer cage 30 are composed of a stainless steel frame and vertical stainless steel bars. The spacing between adjacent vertical stainless steel bars is 5-6 cm, which allows for simple operations on the animals in the cage from outside the transfer cage 30. The two sides of the transfer cage 30 are stainless steel mesh structures, on which drinking water devices, toys and other accessories can be conveniently hung. To facilitate movement, rollers 34 are provided at the four corners of the bottom of the transfer cage 30, and an insertable dirt receiving tray 35 is provided below the cage bottom structure.
