Description

Technical Field

[0001] The utility model relates to the field of laboratory mouse breeding, in particular to a cage changing device for laboratory mice. Background Art

[0002] Changing cages means changing the living place of laboratory mice. Laboratory mice are common organisms used in laboratory experiments. Laboratory mice generally live in incubators. In order to keep the inside of the incubator clean, the inside of the incubator needs to be cleaned regularly during the breeding process.

[0003] At present, the cage changing of experimental mice is generally performed by manually grabbing them. However, since some experimental mice are dangerous and may carry viruses, the grabbers are prone to being bitten or scratched when they are manually grabbed, and even endangering their lives and health. Therefore, a cage changing device for experimental mice is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-4 A cage changing device for experimental mice is provided. The utility model comprises an incubator 1. A rotating device 2 is arranged inside the incubator 1. Two threaded rods 3 which are symmetrically distributed front to back are fixedly connected to the outer side of the rotating device 2. Transmission blocks 4 are connected to the outer sides of the two threaded rods 3 through threaded transmission. The opposite sides of the two transmission blocks 4 are fixedly connected to a first baffle 5 which is slidably connected to the incubator 1. A yield groove is provided on the right side of the incubator 1. A loading box 6 is provided on the right side of the yield groove. A groove is provided inside the loading box 6. A through groove is provided inside the loading box 6. A second baffle 7 which extends to the inside of the groove is provided inside the through groove.

[0028] Among them, the rotating device 2 includes a motor 21 fixedly connected to the outside of the incubator 1, and the outside of the output shaft of the motor 21 is fixedly connected to a first gear 22 located inside the incubator 1. The inner left wall of the incubator 1 is rotatably connected to two rotating shafts 23 that are respectively fixedly connected to the left sides of the two threaded rods 3, and the outer sides of the two rotating shafts 23 are fixedly connected to second gears 24 that mesh with the first gear 22.

[0029] In this embodiment, during actual use, the rotation of the motor 21 drives the first gear 22 to rotate, thereby driving the two second gears 24 to rotate, and further causing the threaded rod 3 connected to the rotating shaft 23 to rotate.

[0030] The incubator 1 is provided with two slide grooves which are symmetrically distributed front to back. The front and rear sides of the first baffle 5 are fixedly connected with sliders 8 which are slidably connected to the two slide grooves respectively.

[0031] In this embodiment, during actual use, the rotation of the threaded rod 3 will drive the first baffle 5 to move. At this time, the slider 8 will move synchronously inside the slide groove to stabilize the moving direction of the first baffle 5.

[0032] A limiting groove is provided inside the incubator 1 , a limiting plate 9 slidably connected to the limiting groove is fixedly connected to the outside of the loading box 6 , and a buckle 10 for engaging with the incubator 1 is provided on the outside of the loading box 6 .

[0033] In this embodiment, during actual use, the docking of the limiting plate 9 and the limiting groove can stabilize the connection between the loading box 6 and the incubation box 1, and the buckle 10 facilitates the fixed connection of the two boxes.

[0034] Among them, two fixing plates 11 are fixedly connected to the top of the loading box 6 and are symmetrically distributed front to back. The insides of the two fixing plates 11 are slidably connected with limiting rods 12 that penetrate through and extend to the inside of the second baffle 7.

[0035] In this embodiment, during actual use, the limiting rod 12 can move leftward to the inside of the second baffle plate 7, and the second baffle plate 7 is confined in the groove, thereby preventing the experimental mouse from running out.

[0036] A buffer pad 13 is arranged on the outer side of the first baffle plate 5 , and a feed trough 14 is arranged inside the loading box 6 .

[0037] In this embodiment, during actual use, the buffer pad 13 fills the gap between the first baffle 5 and the incubator 1, and the feed trough 14 can be filled with feed to lure experimental mice.

[0038] Working principle:

[0039] When you want to change the cage for the experimental mouse, you can first start the motor 21 to rotate the two threaded rods 3 and move the first baffle 5 to the right. At this time, the experimental mouse will be driven to the right by the push of the first baffle 5, and the experimental mouse may also be attracted into the loading box 6 by the feed. Then, the second baffle 7 is lowered and fixed by the limit rod 12. At this time, the experimental mouse is locked in the loading box 6. Then, you can use the interface buckle 10 to remove the loading box 6, and connect the loading box 6 to another incubator 1 to change the cage. The right side of the loading box 6 can also be opened by the lock.
