Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a cage frame of an experimental mouse breeding system. Background Art

[0002] Rats and guinea pigs are experimental animals used in large quantities in biomedical research. Usually, cages are set up to feed the rodents. In order to maintain the health of the mice, the environment inside the cages needs to be kept clean and hygienic.

[0003] Most rodents are raised manually, which is time-consuming and labor-intensive, and the manual control of the feeding amount and water feeding amount is relatively rough. An automatic feeding system for experimental mice is now set up to achieve automated and precise feeding of experimental mice. When using the automatic feeding system, the placement of each feeding cage needs to be more accurately fixed. If the cage moves, it is easy for the automatic feeding system to fail to feed.

[0004] The current cage racks cannot accurately fix the positions of the cage boxes, thus failing to meet the use requirements of the automatic feeding system. Utility Model Content

[0005] Based on the above description, the utility model provides a cage frame for an experimental mouse breeding system to solve the problem that the cage box is difficult to accurately fix on the cage frame.

[0007] Each frame plate is provided with a plurality of positioning blocks along its length direction, and the positioning blocks include corner blocks for abutting against the four corner side walls of the cage box.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the frame plate includes an outer frame and one or more ribs arranged at intervals in the outer frame, and the extending direction of the ribs is parallel to the long side direction of the outer frame.

[0010] Furthermore, a baffle is fixed to the outer side wall of the long side of the outer frame, and the height of the baffle is less than the distance between the two layers of the frame plates.

[0011] Furthermore, after the cage box is placed on the frame plate, the distance between the top of the cage box and the bottom edge of the baffle is greater than the height of the corner block.

[0012] Furthermore, each group of the positioning blocks also includes a prompt structure, which is fixed on the corner block, and the prompt structure corresponding to each cage box is arranged on the same side of the cage box.

[0013] Furthermore, a plurality of fixing seats are arranged at intervals along the length direction of one of the ribs, and a transport track is arranged below the fixing seats.

[0014] Furthermore, the fixing seat includes fixing plates arranged on two opposite side walls of the rib, the rib is clamped between two fixing plates, and a fixing pin is inserted between the fixing plate and the rib.

[0015] Furthermore, a gravity sensing system for sensing the weight of the cage box is provided in the area enclosed by each group of the positioning blocks.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. The cage rack of the present application is provided with multiple groups of positioning blocks on the rack, so that when each cage box is placed on the rack, it can be stuck in the area surrounded by multiple corner blocks, so that the cage box can be accurately placed in the designed position, reducing the movement of the cage box on the rack or the displacement of the placement position, so that the automatic feeding system can accurately feed the cage box;

[0028] The frame plate 1 includes an outer frame 11 and ribs 12 arranged in the outer frame 11. One rib 12 can be provided, or multiple ribs 12 can be provided at intervals. The extending direction of the rib 12 is parallel to the long side direction of the outer frame 11. Specifically, in the embodiment of the present application, the frame plate 1 is provided with five layers, the outer frame 11 is rectangular, and three ribs 12 are provided in each outer frame 11, thereby increasing the number of cage boxes placed and stably supporting the cage boxes.

[0029] Each layer of the shelf 1 is provided with multiple groups of positioning blocks 3 along its length direction, and each group of positioning blocks 3 includes four corner blocks 31. The corner blocks 31 are L-shaped as a whole, and the inner walls of the corner blocks 31 are provided with arc surfaces; a cage box is placed in each group of positioning blocks 3, and when the cage box is set, arc surfaces matching the inner walls of the corner blocks 31 are formed at the corners of the cage box, and when the cage box is placed in a group of positioning blocks 3, the four corner blocks 31 are respectively surrounded at the four corners of the cage box, and the side walls of the cage box are in contact with the inner walls of the corner blocks 31.

[0030] By setting the positioning block 3, the placement position of the cage box can be accurately limited, which is convenient for the staff to place the cage box, and the automatic feeding system can feed the cage box more accurately; the curved surface is set so that the corners of the cage box have a curvature, which improves the handling comfort of the staff.
