Abstract

The utility model discloses a laboratory mouse multi-layer three-dimensional cage structure which comprises a supporting bottom plate for feeding laboratory mice, two ends of the supporting bottom plate extend to form mounting plates, two sides of the supporting bottom plate are provided with side plates, the top of each mounting plate is provided with a separation net, each mounting plate is provided with a ventilation plate, and the other side of each mounting plate is provided with a mounting groove. An inserting groove is formed below the mounting groove, a turning cover plate is mounted in the inserting groove, and a supporting layer is inserted in the inserting groove; a water feeder is installed on the side plate, a feeding opening is further formed in the side plate, and a feeding trough is installed outside the side plate; the multi-layer three-dimensional layout is achieved through the slot type supporting layer, the space utilization rate is increased, the water feeder and the feeding system are independent, the requirement of experimental mice for the activity space is met, and separation net holes are matched with the transparent observation plate to form the three-dimensional activity space; due to the inclined plane design of the feeding trough and the sealing structure of the flip head, the feed residue rate is reduced; the inserting groove type supporting layer is matched with a supporting block locking structure, and the excrement leakage risk is completely eradicated.
