[0043] The following combination Figures 1 to 7 The embodiments of the present utility model are described.

[0044] A ventilation structure in this embodiment includes:

[0045] A cage box 1, wherein a mounting groove 11 is formed on the cage box 1, and a vent hole 12 is formed on the bottom surface of the mounting groove 11;

[0046] The ventilation pipe 2 is provided in the installation groove 11. The ventilation pipe 2 penetrates into the cage box 1 through the ventilation hole 12. The end of the ventilation pipe 2 that penetrates into the cage box 1 is a closed end. A ventilation hole 21 is opened on the pipe body of the ventilation pipe 2.

[0047] The spring 3 is connected between the vent pipe 2 and the bottom surface of the mounting groove 11 to provide elastic force for the vent pipe 2 to stay away from the interior of the cage 1;

[0048] The height limiting ring 4 is fixedly connected to the cage box 1. The height limiting ring 4 includes a deep groove 41 and a shallow groove 42. The bottom surface of the deep groove 41 is a first groove bottom surface 411, and the bottom surface of the shallow groove 42 is a second groove bottom surface 421. The first groove bottom surface 411 is located above the second groove bottom surface 421. The deep groove 41 and the shallow groove 42 are arranged alternately.

[0049] A height-fixing ring 5 is used to limit the height of the vent pipe 2. The height-fixing ring 5 includes a first trapezoidal protrusion 51, and a first inclined sliding surface 511 is provided on the top side of the first trapezoidal protrusion 51. Under the action of the spring 3, the top of the first trapezoidal protrusion 51 abuts against the first groove bottom surface 411 or the second groove bottom surface 421.

[0050] A push tube 6 slides up and down along the vent tube 2. The push tube 6 includes a second trapezoidal protrusion 61. A second inclined sliding surface 611 is provided on the top side of the second trapezoidal protrusion 61.

[0051] When the push tube 6 is pushed downward, the second inclined sliding surface 611 contacts the first inclined sliding surface 511 to push the height-fixing ring 5 downward, so that the first trapezoidal protrusion 51 leaves the deep groove 41 or the shallow groove 42 in which it is located, and then the height-fixing ring 5 is rotated, and the first trapezoidal protrusion 51 rotates to the other shallow groove 42 or the deep groove 41, so that the height-fixing ring 5 limits the vent pipe 2 to another height.

[0052] Depending on the distance that the ventilation tube 2 is pushed into the ventilation hole 12, the ventilation tube 2 will be in a closed position or a ventilation position. In the closed position, the closed end of the ventilation tube 2 closes the ventilation hole 12; in the ventilation position, the ventilation tube 2 is connected with the interior of the cage box 1 through the vent 21 to achieve gas exchange. The position of the ventilation tube 2 can be adjusted through the cooperation between the push tube 6, the spring 3, the height limiting ring 4 and the height fixing ring 5, so as to quickly realize the conversion between the sealing and ventilation of the cage and conveniently adjust the ventilation state of the cage.

[0053] Specifically, a height limiting protrusion 22 is provided on the outer wall of the ventilation pipe 2, and the bottom surface of the height determining ring 5 abuts against the top surface of the height limiting protrusion 22; one end of the spring 3 abuts against the bottom surface of the mounting groove 11, and the other end abuts against the bottom surface of the height limiting protrusion 22, providing an upward elastic force for the ventilation pipe 2.

[0054] The spring 3 abuts against the bottom surface of the height-limiting protrusion 22, providing an upward elastic force for the vent pipe 2, so that the bottom surface of the height-fixing ring 5 and the bottom surface of the height-limiting protrusion 22 on the vent pipe 2 can maintain an abutment state, so that the height position of the vent pipe 2 is determined by the height-fixing ring 5. When the height of the height-fixing ring 5 changes, the height of the vent pipe 2 also changes accordingly. Since the height of the height-fixing ring 5 and the vent pipe 2 are directly limited by the abutment of the bottom and top surfaces, the vent pipe 2 does not need to rotate with the height-fixing ring 5, and it is easy to maintain good airtightness between the vent pipe 2 and the vent hole 12.

[0055] Specifically, the ventilation structure further includes a sealing ring 23 ; the sealing ring 23 is sleeved on the ventilation pipe 2 and is used to seal the gap between the ventilation pipe 2 and the ventilation hole 12 .

[0056] The vent tube 2 and the vent hole 12 are connected in a sliding manner. A gap is left between the vent tube 2 and the vent hole 12. This gap affects the airtightness of the cage 1. A sealing ring 23 is provided in the gap between the vent tube 2 and the vent hole 12 to enhance the airtightness of the cage 1. The sealing ring 23 is usually made of a wear-resistant rubber material and does not affect the sliding connection between the vent tube 2 and the vent hole 12.

[0057] Specifically, the total number of both the deep grooves 41 and the shallow grooves 42 is twice the number of the first trapezoidal bumps 51 .

[0058] It should be noted that when the first trapezoidal protrusion 51 is in the deep groove 41 or the shallow groove 42, it corresponds to the sealing state and the ventilation state of the cage box 1 respectively. When the number of the first trapezoidal protrusions 51 is half of the total number of the deep grooves 41 and the shallow grooves 42, each first trapezoidal protrusion 51 corresponds to exactly one deep groove 41 and one shallow groove 42, so that each time the push tube 6 is pushed, the first trapezoidal protrusion 51 can move from a deep groove 41 to the shallow groove 42 next to the deep groove 41, so that the ventilation pipe moves from the closed position to the ventilation position, completing the switching of the ventilation state.

[0059] Specifically, the first trapezoidal protrusions 51 are evenly arranged along the radial direction on the height-fixing ring 5 ; and the second trapezoidal protrusions 61 are evenly arranged along the radial direction on the push tube 6 .

[0060] The first trapezoidal protrusion 51 and the second trapezoidal protrusion 61 are both evenly arranged along the radial direction, so that the first trapezoidal protrusion 51 and the second trapezoidal protrusion 61 can be docked no matter in which direction, and the second trapezoidal protrusion 61 can evenly apply force to the first trapezoidal protrusion 51 to ensure that the height fixing ring 5 is subjected to balanced force when pushed by the push tube 6.

[0061] Specifically, the height limiting ring 4 is sleeved on the outside of the push tube 6, the inner wall of the height limiting ring 4 is provided with a guide groove, and the outer wall of the push tube 6 is provided with a guide block. The guide block cooperates with the guide groove so that the push tube 6 can slide along the guide groove on the height limiting ring 4.

[0062] When the push tube 6 is pushed to contact the height-fixing ring 5, a force that rotates around the axis of the ventilation tube 2 is generated due to the interaction between the first inclined sliding surface 511 and the second inclined sliding surface 611. If the push tube 6 rotates with the height-fixing ring 5, the cooperation between the first trapezoidal protrusion 51 and the deep groove 41 or the shallow groove 42 will be affected, which may cause inaccurate or unstable switching of the ventilation state. Therefore, it is necessary to limit the rotation of the push tube 6. Through the cooperation between the guide groove and the guide block, the push tube 6 can only slide relative to the height-limiting ring 4. Because the height-limiting ring 4 is fixedly connected to the mounting groove 11, the push tube 6 cannot rotate with the height-fixing ring 5, which will not affect the cooperation between the first trapezoidal protrusion 51 and the deep groove 41 or the shallow groove 42, thereby ensuring accurate switching of the ventilation state.

[0063] Specifically, there are multiple second trapezoidal protrusions 61, and each of the deep grooves 41 or the shallow grooves 42 is correspondingly provided with a second trapezoidal protrusion 61, so that when the push tube 6 slides toward the height-fixing ring 5, at least one second inclined sliding surface 611 contacts the first inclined sliding surface 511.

[0064] The positions of the deep groove 41 and the shallow groove 42 correspond to the positions of the second trapezoidal protrusion 61 inside and outside, that is, each deep groove 41 or shallow groove 42 corresponds to a second trapezoidal protrusion 61, so that no matter the first trapezoidal protrusion 51 is in the deep groove 41 or the shallow groove 42, there is a corresponding second trapezoidal protrusion 61 to push it, which ensures that the switching of the ventilation state is accurate and reliable.

[0065] Specifically, a mouse cage includes the ventilation structure described in the above embodiment.

[0066] A mouse cage according to an embodiment of the second aspect of the present invention also has corresponding beneficial effects because it includes the ventilation structure of the above technical solution.

[0067] The above is a detailed description of the preferred embodiments of the present invention, but the present disclosure is not limited to the embodiments.
