[0002] The peristaltic pump compresses the flexible hose installed in the pump body through one or more rotating rollers or cams. When the roller rotates to extrude the hose, the hose is extruded to reduce the partial cross-sectional area, forcing the internal fluid to move forward. After the roller is released, the hose restores to its original shape, forming a negative pressure area to attract more fluid into the rear part of the hose. With the continuous rotation of the roller, the extrusion and release cycle is repeated continuously to achieve continuous and accurate delivery of the fluid.

[0003] The hose is a key component of the peristaltic pump. The hose is periodically deformed alternately, which is prone to fatigue damage.

[0031] Embodiment 1, as shown in Figure 1 And Figure 2 The detachable shell of a peristaltic pump comprises a pump body 1 and a cover body 2, and the pump body 1 and the cover body 2 are detachably connected through a male buckle 4 and a female buckle 3.

[0032] Specifically, the female buckle 3 is arranged on the cover body 2, and the male buckle 4 is arranged on the pump body 1. The male buckle 4 and the female buckle 3 can be separated by folding the female buckle 3, so that the cover body 2 and the pump body 1 can be quickly disassembled.

[0033] Specifically, two groups of male buckles 4 and female buckles 3 are selected in the embodiment and arranged on the front and back sides of the pump body 1 and the cover body 2 respectively.

[0034] During the folding process of the female buckle 3, the female buckle 3 may be bent and deformed due to excessive folding force of the operator. Preferably, a limiting portion 5 corresponding to the female buckle 3 is arranged, the limiting portion 5 is located on the folding path of the female buckle 3, and after the female buckle 3 is folded to separate from the male buckle 4, the limiting portion 5 contacts the female buckle 3 to block the female buckle 3. After the female buckle 3 is folded, the female buckle 3 is separated from the male buckle 4. In order to avoid damage caused by excessive folding of the female buckle 3, the limiting portion 5 is arranged on the folding path of the female buckle 3. After the female buckle 3 is separated from the male buckle 4, if the female buckle 3 is continued to be folded, the limiting portion 5 can resist the female buckle 3 to avoid further folding of the female buckle 3, thereby protecting the female buckle 3 and avoiding damage caused by excessive folding angle of the female buckle 3.

[0035] Embodiment 2, on the basis of embodiment 1, the limiting portion 5 is arranged on the pump body 1, and the limiting portion 5 is symmetrically distributed on the two sides of the female buckle 3. The limiting portion 5 comprises a limiting surface 51 extending towards the female buckle 3, and the limiting surface 51 contacts the female buckle 3 to block the female buckle 3. When the female buckle 3 is folded, the limiting surface 51 and the female buckle 3 form surface contact to provide sufficient blocking effect and effectively avoid further folding of the female buckle 3.

[0036] Embodiment 3, which is different from embodiment 2 only in that the limiting portion 5 is arranged on the cover body 2.

[0037] In the embodiment 4, on the basis of the embodiment 2, the female buckle 3 comprises a folding arm 31 which can be connected with or separated from the male buckle 4, the folding arm 31 has a notch which is connected with the male buckle 4. The limiting surface 51 contacts with the folding arm 31 to block the female buckle 3. The folding arm 31 contacts with the limiting surface 51, and the limiting surface 51 abuts against the folding arm 31, thereby limiting the rotating angle of the folding arm 31.

[0038] In the embodiment 5, on the basis of the embodiment 4, the folding arm 31 has an extension arm 32 below the folding arm 31, the extension arm 32 extends outwardly from the folding arm 31. The extension arm 32 is an arc-shaped extension arm 32 with elasticity. When the female buckle 3 needs to be folded, the operator can conveniently fold the female buckle 3 by grabbing the extension arm 32 and pulling the extension arm 32, thereby separating the female buckle 3 from the male buckle 4. Further, the surface of the extension arm 32 has a stepped structure. The stepped structure can increase the friction between the extension arm 32 and the hand, and is easier to operate.

[0039] In the embodiment 6, the difference from the embodiment 1 is that the limiting part 5 is installed on the cover 2, and the rest is the same as the above-mentioned embodiments.

[0040] In the embodiment 7, the difference from the embodiment 1 is that the female buckle 3 is arranged on the pump body 1, and the male buckle 4 is arranged on the cover 2.
