The inner diameter of the intermediate pump tube generally has a variety of specifications such as 3.2 mm, 4.8 mm, 6.4 mm, 9.6 mm, 12.7 mm, 15.8 mm, etc. Figure 1 As shown in the figure, the inlet pipe 2 and the outlet pipe 4 connected to the intermediate pump pipe 1 generally have only two specifications of 3.2 mm and 4.8 mm, and the reducer 3 is used to connect the intermediate pump pipe 1 with the inlet pipe 2 and the outlet pipe 4. During each cleaning and sterilization, the hose needs to be pulled out and plugged in, which is cumbersome and has a certain risk of contamination. Utility Model Content

[0022] Example 1

[0023] like Figure 2 and Figure 3 As shown, the integrated pipeline for a linear peristaltic pump of the utility model includes a pipeline body 6, and the pipeline body 6 includes an integrally formed and mutually connected working section 61, a limiting joint section 62, a liquid inlet section 63 and a liquid outlet section 64. The two ends of the working section 61 are respectively provided with a liquid inlet section 63 and a liquid outlet section 64, and a limiting joint section 62 is provided between the working section 61 and the liquid inlet section 63, and between the working section 61 and the liquid outlet section 64. The limiting joint section 62 is used to connect the fixing seat 5 to realize the installation of the pipeline body 6 into the linear peristaltic pump, and the working section 61 is straightened on the side of the pressing tube component of the linear peristaltic pump, the liquid inlet section 63 is used to connect the material source to be filled, and the liquid outlet section 64 is used to connect the filling bottle. The pressing tube component squeezes the working section 61 to realize the material filling and transportation.

[0024] In this embodiment, the working section 61, the limiting joint section 62, the liquid inlet section 63 and the liquid outlet section 64 are integrally formed into the pipeline body 6, so that four are combined into one. When cleaning and sterilizing, it is only necessary to remove the limiting joint section 62 from the fixing seat 5, and the entire pipeline body 6 can be removed. The disassembly and assembly operations are very simple, and the entire pipeline body 6 can be placed in a sterilization device for cleaning and sterilization, which greatly reduces the risk of pipeline contamination.

[0025] like Figure 2As shown, the inner diameter of the tube of the liquid inlet section 63 is equal to the inner diameter of the tube of the liquid outlet section 64. When the inner diameter of the tube of the working section 61 is larger than the inner diameters of the tubes of the liquid inlet section 63 and the liquid outlet section 64, the flow channel inside the limit joint section 62 is a variable diameter structure. When the inner diameter of the tube of the working section 61 is equal to the inner diameter of the tube of the liquid inlet section 63 and the liquid outlet section 64, the flow channel inside the limit joint section 62 can be set as a straight tube channel.

[0026] like Figure 2 As shown, a positioning cone 621 matching the fixing seat 5 is provided on the outer side of the limiting joint section 62 to achieve a detachable connection between the pipeline body 6 and the fixing seat 5 and ensure that the working section 61 is in a straightened state.

[0027] Example 2

[0028] like Figure 4 As shown, the preparation method of the integrated pipeline for a linear peristaltic pump of the utility model has a similar structural setting and working principle as the integrated pipeline for a linear peristaltic pump in Example 1, and the main difference is that: the end of the limiting joint section 62 connected to the liquid outlet section 64 is provided with an identification surface 622, and the identification surface 622 is used to identify the liquid outlet direction of the integrated pipeline. It can be understood that in other embodiments, the identification surface 622 can also be set at the end of the limiting joint section 62 connected to the liquid inlet section 63, and the identification surface 622 is used to identify the liquid inlet direction of the integrated pipeline. To ensure that the liquid inlet direction and the liquid outlet direction of the integrated pipeline are always consistent, reducing the risk of contamination.

[0029] Example 3

[0030] like Figure 5 As shown, the preparation method of the integrated pipeline for a linear peristaltic pump of the utility model has a similar structural setting and working principle as the integrated pipeline for a linear peristaltic pump in Example 1, and the main difference is that: the end of the limiting joint section 62 connected to the liquid outlet section 64 is provided with an identification boss 623, and the identification boss 623 is used to identify the liquid outlet direction of the integrated pipeline. It can be understood that in other embodiments, the identification boss 623 can also be set at the end of the limiting joint section 62 connected to the liquid inlet section 63, and the identification boss 623 is used to identify the liquid inlet direction of the integrated pipeline. To ensure that the liquid inlet direction and the liquid outlet direction of the integrated pipeline are always consistent, reducing the risk of contamination.

[0031] Example 4

[0032] like Figure 6As shown, the preparation method of the integrated pipeline for a linear peristaltic pump of the utility model has a similar structural setting and working principle as the integrated pipeline for a linear peristaltic pump in Example 1, and the difference lies mainly in that an annular positioning boss 624 is provided at the end of the limiting joint section 62, and the positioning boss 624 is clamped on the outside of the fixing seat 5 to realize the detachable connection between the pipeline body 6 and the fixing seat 5. The limiting effect of the positioning boss 624 can also improve the installation stability of the integrated pipeline and prevent the pipeline body 6 from falling off during the operation of the peristaltic pump.
