DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4 The utility model provides a technical solution: an experimental mouse cage frame, comprising an outer shell 1, a ventilation pipe 2, an air nozzle 3, a ventilation window 4, a middle threaded rod 5, an adjustment disk 6, a locking bolt 7, a locking nut 8, a track groove 9, a positioning hole 10, an inner base plate 11, a positioning nut 12, a first card slot 13, a second card slot 14 and a door body 15. A ventilation pipe 2 is vertically fixed in the side wall of the outer shell 1, and an air nozzle 3 is fixedly installed on one side of the ventilation pipe 2. The above structural design can effectively promote the air flow inside and outside the outer shell 1. The ventilation pipe 2 is distributed at equal angles about the center of the outer shell 1. The ventilation pipe 2 is vertically and evenly spaced near the center side of the outer shell 1. The above structural design ensures that the breeding boxes placed on different inner base plates 11 can be fully ventilated;

[0023] When using this device, first turn on Figure 1 The door 15 in the middle is adjusted according to the height of the breeding box. Figure 2 To adjust the spacing of the inner substrates 11, rotate the symmetrically distributed positioning nuts 12 away from the upper and lower surfaces of the center of the inner substrate 11, push the inner substrate 11 with the positioning holes 10 to slide vertically along the middle threaded rod 5 to adjust the spacing, until the vertical distance between the adjacent inner substrates 11 is appropriate, rotate the symmetrically distributed positioning nuts 12 to reset and squeeze the inner substrate 11 to fix it;

[0024] The top and bottom of the outer shell 1 are both provided with ventilation windows 4, which are symmetrically distributed at the top and bottom of the outer shell 1, and are distributed at equal angles about the center of the outer shell 1. The top view shape of the ventilation windows 4 is fan-shaped, and the width of the ventilation windows 4 is not less than 1 / 3 of the radius of the outer shell 1. The above structural design ensures that the air inside and outside the outer shell 1 can flow smoothly. A middle threaded rod 5 is installed through the bearing seat at the center of the outer shell 1, and an adjusting disk 6 is fixed at the bottom end of the middle threaded rod 5. A locking bolt 7 is fixed to the edge of the top surface of the adjusting disk 6, and a locking nut 8 is installed in the middle of the locking bolt 7. The top of the locking bolt 7 is fitted with one side of the inner wall of the track groove 9, and the track groove 9 is opened in the middle of the outer bottom surface of the outer shell 1. The locking bolt 7 and the track groove 9 are slidably connected, and the front view section of the track groove 9 is "T"-shaped, and the upward view shape of the track groove 9 is circular. The above structural design can prevent the locking bolt 7 from disengaging from the track groove 9, and enable the adjusting disk 6 to carry the locking bolt 7 to perform smooth rotation along the track groove 9;

[0025] The middle threaded rod 5 passes through the positioning hole 10, which is opened at the center of the inner substrate 11. The mesh diameter on the inner substrate 11 is smaller than the mesh diameter on the ventilation window 4. The distance between the edge of the inner substrate 11 and the inner wall of the outer shell 1 is greater than the length of the air nozzle 3. The above structural design allows air to pass through the inner substrate 11 smoothly, facilitating gas exchange between the inner and outer shell 1, while avoiding collision between the inner substrate 11 and the air nozzle 3.

[0026] The center surface of the inner base plate 11 is fitted with the positioning nut 12, and the positioning nut 12 is installed on the middle threaded rod 5. The top edge of the inner base plate 11 is provided with a first card slot 13 and a second card slot 14. The positioning nut 12 is symmetrically distributed about the inner base plate 11. The inner base plate 11 is made of a fine stainless steel wire mesh. The edge of the inner base plate 11 is provided with a first card slot 13 and a second card slot 14 at equal angles. The first card slot 13 and the second card slot 14 are alternately distributed. The above structural design enables air to flow smoothly through the inner base plate 11. The first card slot 13 and the second card slot 14 can densely place feeding boxes of different lengths. A door body 15 is installed on the front of the outer shell 1;

[0027] Then, the feeding boxes of different lengths are pushed horizontally into the first slot 13 and the second slot 14. The adjusting plate 6 can be rotated to drive the middle threaded rod 5 and the inner base plate 11 to rotate, and the empty first slot 13 and the second slot 14 are aligned with the opened door body 15 to facilitate the placement of the feeding boxes. Then, the door body 15 is closed and the upper screw is turned.
