[0004] In the prior art, mouse cages often only have the function of separating and feeding mice, so it is necessary to design a mouse cage that is convenient for mice to excrete and collect feces. China Authorization Announcement No. CN216627040 U discloses a convenient mouse feeding cage. Although this solution can collect feces without taking out the mice, it does not create a feeding environment that is convenient for mice to excrete. Summary of the invention

[0005] The technical solution to be solved by the utility model is to provide a mouse cage that is convenient for feces sampling. By improving the overall structure of the mouse cage and designing two breeding environments, light and dark, when feces need to be collected and studied, mice are driven to a dark environment to facilitate their defecation.

[0006] The technical scheme adopted by the utility model is: a mouse cage convenient for feces sampling, comprising a mouse cage frame with a bottom plate, a light-proof room and a light-transmitting cage arranged on the left and right sides of the mouse cage frame for mouse activities, and a left collecting box and a right collecting box respectively arranged at the bottom of the light-proof room and the light-transmitting cage, wherein the light-proof room is composed of a left side plate, a middle plate, a left front plate, a left rear plate, a left lower mesh plate and a left upper sliding plate arranged at the left half of the mouse cage frame, and the light-transmitting cage is composed of a right side plate and a square cage arranged at the right half of the mouse cage frame, and a hole for connecting the light-proof room and the light-transmitting cage and a matching closed door are provided in the middle of the middle plate.

[0007] Furthermore, the squirrel cage frame includes a bottom plate, a left lower support rod, a left upper support rod, a left front column, a left rear column, a right lower support rod, a right upper support rod, a right front column, a right rear column, a front lower support cross bar, a rear lower support cross bar, a front upper support cross bar, and a rear upper support cross bar; the bottom plate is arranged on a frame composed of a left lower support rod, a right lower support rod, a front lower support cross bar, and a rear lower support cross bar.

[0008] Furthermore, slide grooves are arranged on the inner sides of the front upper supporting cross bar and the rear upper supporting cross bar, and the left upper sliding plate is arranged in the slide grooves.

[0009] Furthermore, the length of the upper left sliding plate along the sliding groove direction is equal to 1 / 2 of the length of the upper front supporting cross bar.

[0010] Furthermore, the closed door includes a rotating shaft arranged above the hole, a door panel hinged on the rotating shaft, and a return spring arranged on the rotating shaft and used for opening and closing the door panel.

[0011] Furthermore, the left collecting box and the right collecting box are respectively arranged on the squirrel cage frame by means of square plug holes at the lower parts of the left side plate and the right side plate.

[0012] Furthermore, the left collection box and the right collection box have the same structure, including: a drawer-type body, a filter net arranged on the storage space in the drawer-type body, and absorbent paper laid on the filter net.

[0013] The utility model has the beneficial effects that the overall structure of the mouse cage is improved, and two feeding environments, light and dark, are designed. When it is necessary to collect and study feces, mice are driven to the dark environment to facilitate their defecation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] See attached Figure 1-2A mouse cage for convenient feces sampling comprises a mouse cage frame 1 with a bottom plate 1-1, a light-proof room and a light-transmitting cage for mouse activities arranged on the left and right sides of the mouse cage frame 1, and a left collecting box 4 and a right collecting box 5 respectively arranged at the bottom of the light-proof room and the light-transmitting cage, wherein the light-proof room is composed of a left side plate 2-1 arranged on the left half of the mouse cage frame 1, a middle plate 2-2, a left front plate 2-3, a left rear plate 2-4, a left lower mesh plate 2-5 and a left upper sliding plate 2-6, and the light-transmitting cage is composed of a right side plate 3-1 and a square cage 3-2 arranged on the right half of the mouse cage frame 1, and a hole 2-2-1 for connecting the light-proof room 2 and the light-transmitting cage 3 and a matching closed door 2-2-2 are opened in the middle of the middle plate 2-2. The left and right sides of the square cage 3-2 are respectively fixed on the middle plate 2-2 and the right side plate 3-1.

[0019] The squirrel cage frame includes a bottom plate 1-1, a lower left support rod, an upper left support rod, a left front column, a left rear column, a lower right support rod, an upper right support rod, a right front column, a right rear column, a front lower support cross bar, a rear lower support cross bar, a front upper support cross bar, and a rear upper support cross bar; the bottom plate 1-1 is arranged on a frame composed of a lower left support rod, a lower right support rod, a front lower support cross bar, and a rear lower support cross bar.

[0020] The front upper support cross bar and the rear upper support cross bar are provided with a slide groove 1-2 inside, and the left upper sliding plate 2-6 is arranged in the slide groove 1-2. The length of the left upper sliding plate 2-6 along the slide groove 1-2 direction is equal to 1 / 2 of the length of the front upper support cross bar 1-12.

[0021] The closed door 2-2-2 includes a rotating shaft arranged above the hole 2-2-1, a door panel 2-2-2-2 hinged on the rotating shaft, and a return spring arranged on the rotating shaft and used for opening and closing the door panel. With the preload of the return spring, the door panel is tightly fitted at the hole 2-2-1.

[0022] The left collection box 4 and the right collection box 5 are respectively arranged on the squirrel cage frame 1 by means of the square plug holes 6 at the lower parts of the left side plate 2-1 and the right side plate 3-1.
