[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figures 1-4 The peristaltic pump casing shown includes a lower housing 1, a partition 2, an upper housing 3, and a flexible hose 4. The lower housing 1 is a hollow structure with an open upper end and is installed at the lower end of the partition 2. The lower housing 1 and the partition 2 form a drive cavity for mounting a transmission assembly. The upper housing 3 is a hollow shell with an open lower end and is installed at the upper end of the partition 2. The upper housing 3 and the partition 2 form a rotor cavity for mounting a rotor. The flexible hose 4 is wound around the outer periphery of the rotor cavity, with both ends of the flexible hose 4 extending out of the rotor cavity. A connecting hole 21 is provided on the partition 2, through which the transmission assembly passes and connects to the rotor to drive the rotor.

[0025] like Figure 2 As shown, a motor mount 11 for mounting a motor is fixed to the side of the lower housing 1. A motor shaft hole 111 is provided between the motor mount 11 and the lower housing 1. The motor is fixed in the motor mount 11 by bolts. The output shaft of the motor extends into the lower housing 1 through the motor shaft hole 111 and is connected to the transmission assembly. The transmission assembly can be a bevel gear assembly or a worm gear assembly, as long as it can achieve 90-degree transmission.

[0026] When the height of the motor base 11 is greater than the height of the lower housing 1, a protrusion with the same cross-section as the motor base 11 is fixed on the opposite side of the lower housing 1, so that the upper end face of the lower housing 1 has a symmetrical structure, which facilitates the swapping of the partition 2.

[0027] like Figure 1 , Figure 3 , Figure 4As shown, partition 2 is a rectangular plate, and the connecting hole 21 is a circular hole located at the center of partition 2. Two first protrusions 22 are fixed to the right end of the upper surface of partition 2, perpendicular to the upper surface of partition 2, with their tops forming a semi-circular arc. Two second protrusions 23 are fixed to the left end of partition 2, perpendicular to the upper surface of partition 2, with their tops forming a semi-circular through-hole groove. Two identical grooves 32 are respectively formed at the left and right ends of the upper housing 3, with the tops of the grooves forming a semi-circular arc. The widths of the first protrusions 22 and second protrusions 23 are equal to the outer diameter of the flexible hose 4, and the inner diameters of the through-hole grooves and the tops of the grooves 32 are also equal to the outer diameter of the flexible hose 4. When the upper housing 3 is connected to the partition plate 2, the first boss 22 and the second boss 23 extend into the grooves 32 on both sides of the upper housing 3 respectively. The first boss 22 is tightly connected to the groove 32, and a circular through hole for the hose 4 to pass through is formed between the second boss 22 and the groove 32.

[0028] like Figure 3 , Figure 4 As shown, a first arc-shaped plate 24 is vertically installed between the first boss 22 and the connecting hole 21, and the first arc-shaped plate 24 is concentrically arranged with the connecting hole 21. Two second arc-shaped plates 31 are symmetrically fixed inside the upper housing 3, and the two second arc-shaped plates 31 are symmetrically arranged on the front and rear sides of the upper housing 1, and are concentrically arranged with the connecting hole 21. When the upper housing 3 is installed on the partition plate 2, the first arc-shaped plate 24 is inserted between the two second arc-shaped plates 31, so that the two second arc-shaped plates 31 and the first arc-shaped plate 24 form a flexible hose abutment with its opening facing the through-hole.

[0029] like Figure 5 As shown, when the second boss 23 is located at the left end, the through hole is also located at the left end, and the peristaltic pump interface is also located at the left end. When the partition 2 is rotated 180° so that the first boss 22 is located at the left end, the through hole is located at the right end, and the peristaltic pump interface is also located at the right end. By changing the position of the partition 2, the direction of the peristaltic pump interface can be changed to adapt to different installation requirements.

[0030] like Figures 1-4 As shown, four snap-fit ​​posts 33 are fixed to the lower end face of the upper shell 3, and the four snap-fit ​​posts 33 are located at the four corners of the upper shell 3. A snap-fit ​​block 34 is fixed to the lower end of each snap-fit ​​post 33. Snap-fit ​​grooves 12 that mate with the snap-fit ​​blocks 34 are formed around the upper end face of the lower shell 1. The snap-fit ​​blocks 34 snap into the snap-fit ​​grooves 12, connecting the upper shell 3 and the lower shell 1, and pressing the partition 2 between the upper shell 3 and the lower shell 1. The partition 2 has four clearance grooves 26 on its side that mate with the snap-fit ​​posts 33. The snap-fit ​​posts 33 are inserted into the clearance grooves 26, limiting the horizontal movement of the partition 2.

[0031] like Figure 2-4As shown, two symmetrical positioning grooves 25 are formed on the edge of the partition 2, penetrating the upper and lower surfaces of the partition 2. Two first positioning pins 13 are fixed to the upper end face of the lower housing 1, and two second positioning pins 35 are fixed to the lower end face of the upper housing 3. The shapes and positions of the first positioning pins 13 and second positioning pins 35 are matched with the positioning grooves 25, and the height of the first positioning pins 13 and second positioning pins 35 is less than half the depth of the positioning grooves 25 to avoid the first positioning pins 13 and second positioning pins 35 abutting during assembly, thus affecting the assembly accuracy of the upper housing 3 and lower housing 1. During installation, the first positioning pins 13 and second positioning pins 35 are first inserted into the positioning grooves 25 to achieve preliminary positioning of the upper housing 3 and lower housing 1, thereby improving the ease of assembly. Furthermore, the cooperation between the first positioning pins 13 and second positioning pins 35 and the positioning grooves 25 also improves the stability of the pump housing connection.

[0032] like Figure 4 As shown, the upper housing 3 also has heat dissipation holes 36, located on the outer side of the flexible hose abutment plate. A dust cover (not shown) is installed at the heat dissipation holes 36. Adding heat dissipation holes 36 improves the heat dissipation performance of the peristaltic pump, preventing excessive motor temperature when conveying high-temperature media and extending the motor's service life. Preferably, the dust cover is a waterproof and breathable membrane. The dust cover prevents dust and moisture from entering while allowing air circulation, ensuring heat dissipation performance while preventing corrosion of the internal parts of the peristaltic pump caused by moisture and dust.

[0033] The technical solutions provided in this application have at least the following technical effects or advantages:

[0034] By reversing the direction of the partition, the first boss can be fitted with grooves on different sides. At the same time, the first arc plate and the two second arc plates can be fitted together to change the opening of the hose abutment, thereby changing the direction of the peristaltic pump interface. This eliminates the need for an adapter, saves installation costs, and improves installation efficiency.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
