[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5A novel peristaltic pump mounting structure includes a base plate 1, which is L-shaped. A top cover 13 with openings at both ends and the bottom is mounted on the top of the base plate 1, corresponding to the base plate 1 to form a rectangular shell. Slide grooves 15 are installed on both sides inside the base plate 1. Strip sliders 16 corresponding to the slide grooves 15 are installed on both sides of the top cover 13. A first mounting seat 12 is installed at the bottom corner of the base plate 1, and a second mounting seat 14 corresponding to the first mounting seat 12 is installed at the bottom corner of the top cover 13. The sliding of the strip sliders 16 in the slide grooves 15 provides a limiting effect for the installation of the top cover 13 on the base plate 1, so that the top cover 13 and the base plate 1 can be installed by bolts or screws through the two overlapping mounting seats and fixed to the operating table or other table surface.

[0028] like Figure 3 and Figure 4 As shown, an annular seat 2 is vertically mounted on the side of the base plate 1. A drive shaft 35 is coaxially arranged inside the annular seat 2, passing through the base plate 1 and rotatably connected to it. A turntable 3 is also provided inside the annular seat 2, coaxially mounted on the drive shaft 35. Several rollers 4 are installed at intervals along the edge of the turntable 3. A flexible hose 5 is provided along the inner wall of the annular seat 2, placed between the rollers 4 and the inner wall of the annular seat 2. The ends of the flexible hose 5 are respectively connected to an inlet 6 and an outlet 7. The inlet 6 and outlet 7 are mounted on the annular seat 2. On the side of seat 2; a coupling 8 is connected to the other end of the drive shaft 35, and a reducer 9 is installed on the other end of the coupling 8. The reducer 9 is installed on the base plate 1 through the support frame 10. A drive motor 11 is installed on the other side of the reducer 9. The operation of the drive motor 11 provides power for the squeezing operation of the roller 4 on the hose 5. It should be noted that a control cabinet 17 is installed on the top inside the top cover 13. A controller is installed in the control cabinet 17. The controller is connected to the reducer 9 and the drive motor 11 through wires. The controller is a control main board.

[0029] To ensure airflow between the top cover 13 and the base plate 1, cooling fans 18 are installed on both sides of the top cover 13. The cooling fans 18 are connected to the controller via wires to dissipate heat from the drive motor 11 and the reducer 9. A dustproof net 19 is installed on the outside of the cooling fans 18 and is fixed to the top cover 13 with fasteners to reduce dust and other debris from falling from the cooling fans 18 onto the output end of the drive motor 11 or the output end of the reducer 9, thereby affecting the normal operation of the drive motor 11 and the reducer 9.

[0030] like Figure 4 As shown, an annular limiting seat 20 is installed along the edge of the annular seat 2 away from the base plate 1. The limiting seat 20 has multiple spaced limiting grooves 21 that penetrate the side of the limiting seat 20. Figure 2 and Figure 5As shown, a circular cover plate 22 is provided on the side of the annular seat 2 away from the base plate 1. A cavity 23 is correspondingly formed inside the cover plate 22. A lead screw 25 is provided inside the cavity 23. The lead screw 25 is arranged along the radial direction of the cover plate 22. One end of the lead screw 25 is rotatably mounted on the inner wall of the cavity 23, and the other end of the lead screw 25 is rotatably mounted on a fixed seat 36. The fixed seat 36 is coaxially fixed to the side of the cavity 23. A strip groove 24 corresponding to the lead screw 25 is formed on the side of the cover plate 22 near the annular seat 2, and a threaded connection is made to the lead screw 25. The connecting rod 26 has an arc-shaped limiting plate 27 connected to the other end of the strip groove 24. The limiting plate 27 is coaxial with the annular seat 2. After the cover plate 22 is placed on the end of the annular seat 2, the limiting plate 27 can be pressed against the outer wall of the annular seat 2 by the rotation of the screw 25. The connecting rod 26 will also fall into the limiting groove 21 due to the movement of the limiting plate 27, so that the side of the limiting plate 27 can be correspondingly attached to the side of the limiting seat 20, thereby fixing the cover plate 22 on the annular seat 2 and sealing the inner cavity of the annular seat 2.

[0031] A first bevel gear 28 is coaxially mounted on one end of the lead screw 25 near the fixed seat 36. A second bevel gear 29 meshes with the first bevel gear 28. A rotating rod 30 is coaxially mounted on the second bevel gear 29. The rotating rod 30 passes through the cover plate 22 and is connected to a handle 31. The rotating rod 30 is rotatably connected to the cover plate 22. When the handle 31 is rotated, the rotation of the lead screw 25 can be controlled through the transmission between the bevel gears. This allows the rotating rod 30 to simultaneously control the movement of multiple limit plates 27, thereby improving the ease of disassembling the cover plate 22 and facilitating the disassembly of the cover plate 22 when the hose 5 needs to be replaced.

[0032] After the limiting plate 27 is fixed on the annular seat 2, a locking bolt 34 is threaded on one side of the handle 31. The end of the locking bolt 34 corresponds to the side of the cover plate 22. Tightening the locking bolt 34 allows the end of the locking bolt 34 to abut against the side of the cover plate 22, thereby locking and fixing the handle 31. This prevents the screw 25 from rotating unnecessarily when the peristaltic pump is operating, which would affect the fixation of the cover plate 22 on the annular seat 2.

[0033] It needs to be further explained that, such as Figure 3 and Figure 4 As shown, a limiting hole 37 is provided on the limiting seat 20, and a limiting rod 38 corresponding to the limiting hole 37 is installed on the cover plate 22. When the cover plate 22 is placed on the annular seat 2, the correspondence between the limiting rod 38 and the limiting hole 37 helps the connecting rod 26 to correspond with the limiting groove 21, so that the cover plate 22 can be quickly installed on the annular seat 2.

[0034] Furthermore, slide rails 33 are installed on both sides of the strip groove 24 along the length of the strip groove 24. Slider 32 is slidably installed on the slide rails 33 and fixed on the connecting rod 26. The slider 32 limits the movement of the limiting plate 27, thereby improving the stability of the limiting plate 27 when it moves.

[0035] It should be noted that an elastic rubber pad is installed on the inner wall of the limiting plate 27. When the limiting plate 27 is pressed against the outer wall of the annular seat 2, the rubber pad will generate a reverse force on the limiting plate 27, thereby ensuring the fastening of the connecting rod 26 on the lead screw 25.

[0036] Specifically, when it is necessary to open the cover plate 22 to inspect and replace the hose 5, first turn the locking bolt 34, then turn the handle 31 to move the limiting plate 27 away from the annular seat 2. When the limiting plate 27 is removed from the limiting seat 20, the cover plate 22 can be removed from the annular seat 2. At this time, the hose 5 can be inspected and replaced. Then repeat the above operation, place the cover plate 22 on the annular seat 2, turn the handle 31 again, and turn the locking bolt 34 to complete the fixation of the cover plate 22 on the annular seat 2.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
