Description

Technical Field

[0001] The utility model relates to the technical field of animal cages, in particular to a breeding box which is convenient for changing cages of animals. Background Art

[0002] Currently, most widely used experimental mouse cages are one-piece box structures, or split structures with a wire cage connected to a bedding box with clips. When the mouse needs to be changed cages, the mouse is taken out and transferred to another cage by opening a switch door set on the top or front side. This cage changing method requires manual control of the mouse. However, the mouse may escape or attack due to fear during the transfer, resulting in researchers being easily bitten or the mouse escaping to the corner of the laboratory during the cage changing process. The safety and convenience are both low. Utility Model Content

[0003] The technical problem to be solved by the utility model is that in the process of changing cages in traditional breeding boxes, researchers are easily bitten or mice escape to the corners of the laboratory, and the safety and convenience are low.

[0004] The U-shaped bracket is located between the upper and lower portions of the rear frame and the lower frame, and the U-shaped bracket is located between the upper and lower portions of the rear frame and the upper frame.

[0005] As a further solution of the present utility model, a driving structure is provided in the U-shaped frame, and the driving structure includes a motor located on one side of the U-shaped frame, a screw is provided at the output end of the motor, a moving block is threadedly connected to the screw, and the moving block is slidably connected to the top surface of the U-shaped frame, a push plate is provided under the moving block, and an electric telescopic rod is provided on the side of the push plate close to the partition, a sponge block is provided at the output end of the electric telescopic rod, and a distance sensor is provided on the push plate.

[0006] As a further solution of the present invention, an opening and closing door is provided on the U-shaped frame, a plurality of evenly distributed air holes are provided on the U-shaped frame, and a padding drawer matching the inner size of the U-shaped frame is movably provided inside the U-shaped frame.

[0007] As a further solution of the present invention, the vertical plate is provided with a transparent acrylic window, a padding partition plate and a drawer opening for allowing a padding drawer to pass through in sequence from top to bottom, and a handle is provided on the front of the padding drawer.

[0008] As a further solution of the present invention, a cage changing box is provided on the side of the feeding box body close to the partition, which is arranged opposite to its structure. A limit plate is rotatably provided in front of the feeding box body, and a locking groove is provided on the limit plate. A limit rod corresponding to the position of the locking groove is provided in the front of the cage changing box.

[0009] As a further solution of the present invention, a connecting plate is provided on the top surface of the U-shaped frame, and one end of the screw extending into the U-shaped frame is rotatably connected to the connecting plate.

[0010] The advantages of this utility model compared with the prior art are:

[0011] 1. By setting the partition to slide in the slide rail, pull the L-shaped positioning rod to pull the positioning rod out of the slot, release the positioning of the partition, and then pull the partition up to form a passage between the feeding box body and the changing cage box, so that the mice can be transferred to the changing cage box. After the transfer is completed, the partition is lowered. When the slot is realigned with the L-shaped positioning rod, release the pull block spring to drive the L-shaped positioning rod to reinsert the slot to position the partition. This structure does not require researchers to manually change the cage of mice, which is more convenient and safer.

[0012] 2. By setting up a driving structure, when changing cages, the motor drives the screw to rotate, and the screw drives the moving block to move toward the direction of the channel, and the moving block drives the push plate to move. At the same time, the electric telescopic rod performs reciprocating telescopic motion, driving the sponge block to push the mouse. The fear of the mouse is used to autonomously find the channel position for transfer, and the distance sensor is used to detect the position of the mouse from the push plate. When the distance is less than the set safety value, the distance sensor sends an electrical signal to the motor to stop the motor and the push plate. The electric telescopic rod continues to move until the mouse starts to move to a safe distance and the motor starts again. This structure can speed up the efficiency of mouse cage changing;

[0013] 3. By setting a locking groove on the limit plate and rotating the limit plate so that the locking groove is engaged with the limit rod on the cage changing box, the stability of the connection between the feeding box and the cage changing box can be maintained, avoiding the situation where the connection channel is misaligned due to external forces and mice run out of the gap.
