[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a carbon dioxide incubator that facilitates gas path installation, including an incubator 1, a connecting pipe 2, and a delivery pipe 3. The connecting pipe 2 is provided on one side of the outer wall of the incubator 1. A connecting assembly is provided between the delivery pipe 3 and the connecting pipe 2. A frame 9 is fixedly sleeved on the outside of the connecting pipe 2. A lifting assembly is provided in the inner cavity of the frame 9. A pressing plate 13 is provided at the bottom end of the lifting assembly. Through the setting of the connecting assembly, the delivery pipe 3 and the connecting pipe 2 can be quickly and stably connected, solving the problem of unstable gas path installation structure and frequent loosening of rotating bolts in the actual use of the existing carbon dioxide incubator 1. Through the setting of the lifting assembly, the pressing plate 13 can press the connecting pipe 2, thereby facilitating the opening and closing of the connecting pipe 2. The operation is simple and convenient.

[0022] In this embodiment, the connecting assembly includes a nut 4, a baffle 5, a connector 6, a spring 7, and a washer 8. The nut 4 is rotatably connected to one end of the delivery pipe 3 via a sealed bearing. The baffle 5 is fixedly sleeved on the end of the connecting pipe 2 away from the incubator 1. The connector 6 is fixedly connected to the right side of the baffle 5. The spring 7 is located at the end of the nut 4 near the connecting pipe 2, and the washer 8 is located at the end of the spring 7 away from the nut 4. The nut 4 is screwed onto the outside of the connector 6. Rotating the nut 4 causes it to be screwed onto the connector 6, allowing the nut 4 and the baffle 5 to cooperate in compressing the spring 7 and the washer 8. This causes the spring 7 to undergo corresponding elastic deformation and generate corresponding elastic force. Under the action of the elastic force of the spring 7, the pressure between the inner thread of the nut 4 and the outer thread of the connector 6 increases, thereby increasing the friction between them and improving the stability of the connection. This solves the problem of unstable gas path installation structure and frequent loosening of rotating bolts in the actual use of the existing carbon dioxide incubator 1.

[0023] In this embodiment, the lifting assembly includes a fixed cylinder 10, a lead screw 11, a knob 12, and a telescopic assembly. The fixed cylinder 10 is located at the top of the frame 9. The lead screw 11 is screwed into the inner cavity of the fixed cylinder 10. The knob 12 is located at the top of the lead screw 11. The bottom end of the lead screw 11 is rotatably connected to the top of the extrusion plate 13 through a bearing. The telescopic assembly is located between the top of the inner cavity of the frame 9 and the extrusion plate 13. Rotating the knob 12 causes the lead screw 11 to rotate. Under the action of the rotational force of the thread on the outer wall of the lead screw 11, when the lead screw 11 rotates, the extrusion plate 13 can slide downward in a straight line under the combined action of the telescopic rod 15 and the telescopic cylinder 14, so that the extrusion plate 13 extrudes the connecting pipe 2. This allows for convenient control of the opening and closing of the connecting pipe 2. The operation is simple and convenient.

[0024] In this embodiment, multiple anti-slip bars are provided on the outer circumference of the knob 12.

[0025] In this embodiment, the telescopic assembly includes a telescopic cylinder 14, a telescopic rod 15, and a limiting assembly. The telescopic cylinder 14 is disposed at the top of the extrusion plate 13. The telescopic rod 15 is slidably inserted into the inner cavity of the telescopic cylinder 14 and fixedly connected to the top of the inner cavity of the frame 9. The limiting assembly is disposed in the inner cavity of the telescopic cylinder 14 and fixedly connected to the outer wall of the telescopic rod 15. When the extrusion plate 13 slides up and down, the telescopic rod 15 can extend or retract in the inner cavity of the telescopic cylinder 14 accordingly. Under the combined action of the telescopic rod 15 and the telescopic cylinder 14, the extrusion plate 13 can always slide up and down along a straight line, and it can also prevent the extrusion plate 13 from rotating with the lead screw 11 when the lead screw 11 rotates.

[0026] In this embodiment, the limiting component includes a limiting groove 16 and a limiting block 17. The limiting groove 16 is formed on the inner wall of the telescopic cylinder 14, and the limiting block 17 is slidably embedded in the inner cavity of the limiting groove 16 and fixedly connected to the outer wall of the telescopic rod 15, so that one end of the telescopic rod 15 is always inserted into the inner cavity of the telescopic cylinder 14.

[0027] In this embodiment, the inner cavity of the limiting groove 16 and the outer wall of the limiting block 17 are adapted to each other and are both in the shape of a "T".

[0028] In this embodiment, both the connecting pipe 2 and the delivery pipe 3 are rubber hoses.
