Description

TECHNICAL FIELD

[0001] The utility model relates to peristaltic pump field especially a peristaltic pump convenient to dismouting replacement. BACKGROUND

[0002] Peristaltic pump is a kind of pump to the elastic hose is alternately extruded and released to transport fluid, when pump operation, the roller in pump head will let the convex part that oneself has extruded on hose and do circumferential motion along hose, let the convex part that oneself is extruded in order to the hose, make a series of pressure wave in hose, to push fluid in hose flow in one direction, from the end of hose is transported to the other end, after the convex part of roller leaves hose, hose will rely on the elasticity of original state, to prepare the next cycle of delivery, peristaltic pump is commonly used in small household appliance field, and its pump head is often disposable, needs to be replaced after using certain time, but the peristaltic pump of prior art needs to drive assembly and the roller meshing form transmission connection, the gear set and other components in drive assembly will be installed in the cavity formed between pump head and pump body with roller, this makes these drive components easy to scatter when dismounting and replacing pump head, and pump head and pump body are often connected using bolt fixing mode, and it is very inconvenient to replace. SUMMARY

[0003] In view of the defects of the prior art, the utility model provides a peristaltic pump convenient to dismouting replacement, which is not easy to scatter during dismounting and is convenient for replacing pump head.

[0004] To achieve the above object, the utility model provides a peristaltic pump convenient to dismouting replacement, which comprises a pump head and a pump body, the pump head is provided with a pump pipe and a roller part, the pump body is provided with a gear set, further comprising a connecting piece, the connecting piece comprises a partition plate, a plurality of first connecting parts and a plurality of second connecting parts, the partition plate is arranged between the pump body and the pump head, a plurality of the first connecting parts and the second connecting parts are arranged to extend towards the pump head and the pump body respectively, and the first connecting part and the second connecting part can be respectively connected with the pump head and the pump body, the pump body is provided with a meshing part in transmission connection with the gear set, and the meshing part can pass through the partition plate and extend into the pump head to mesh with the roller part.

[0005] The advantages of the above technical scheme are: by arranging the connecting piece between the pump body and the pump head, arranging the partition plate, the first connecting parts and the second connecting parts on the connecting piece, allowing the first connecting parts to be connected with the pump head and the second connecting parts to be connected with the pump body, the independent connection between the pump head and the pump body is relatively independent, when the pump head needs to be replaced, the pump head can be separated from the connecting piece by only releasing the connection between the first connecting parts and the pump head, without needing to operate the connection between the pump body and the connecting piece too much, greatly simplifying the process of replacing the pump head, and in the process of replacing the pump head, since the partition plate and the connecting piece are designed, only the connection between the pump head and the first connecting parts needs to be released, without needing to disassemble multiple bolts, nuts or other complex connecting parts, facilitating disassembly and assembly, without affecting the gear set and other parts inside the pump body, avoiding problems such as disassembly or displacement caused by disassembly of the pump head.

[0006] The utility model discloses further can set up as: first connecting part and second connecting part circumferential interval be arranged at the edge of partition plate, and first connecting part and second connecting part respectively extend to the first buckling part and the second buckling part that form towards pump head and pump body, pump head and pump body all be provided with containing groove and the clamping block in containing groove, and first buckling part and second buckling part can form the connection of buckling cooperation with corresponding clamping block.

[0007] By further setting, the first connecting part and the second connecting part are circumferentially spaced apart at the edge of the partition plate, which can uniformly distribute the connection force between the pump head and the pump body in the circumferential direction, and when the peristaltic pump operates to generate vibration or is subjected to external force, each connecting part can jointly bear and disperse the force, avoiding local overloading to cause connection failure, and ensuring the stability of the entire structure in each direction.

[0008] The utility model discloses further can set up as: first buckling part and second buckling part can be flush with the outer wall of corresponding pump head and pump body after being placed in containing groove.

[0009] By further setting, when the first buckling part and the second buckling part are flush with the outer wall of the pump head and the pump body, the appearance of the entire peristaltic pump is more regular, the connection between each part is more smooth, and on the basis of being more beautiful, the external protruding part is reduced, the influence of external factors such as collision and friction on the buckling part during use is reduced, and the stability is stronger.

[0010] The utility model discloses further can set up: the engagement of department includes the boss and a plurality of engagement teeth, the boss is cylindrical, and the boss rotation is arranged on the partition board, a plurality of the engagement tooth is arranged on the boss in the circumferential interval, and the engagement tooth corresponds the two sides of circumferential respectively and is provided with abutting plane and inclined arc surface.

[0011] Through further setting, the cylindrical boss rotation is arranged on the partition board, provides stable rotation support for the engagement, guarantees the concentricity in the power transmission process, reduces the vibration and noise produced because of eccentricity, and the inclined arc surface plays the buffering effect in the engagement process, reduces the impact force of engagement instant, reduces the wear speed of the engagement tooth and the roller piece, and the larger contact area of abutting plane makes the pressure distribution more uniform, avoids the local stress concentration, further reduces the wear, prolongs the service life of the engagement and the roller piece.

[0012] The utility model discloses further can set up: the roller piece includes the axle and the cylinder, the axle is along the circumferential distribution of roller piece and is arranged, and the cylinder rotation is sleeved on the axle.

[0013] Through further setting, the cylinder can rotate freely on the axle, when it contacts and extrudes the hose, is the rolling friction and not sliding friction, and the heat and wear degree produced by rolling friction are far lower than sliding friction, which greatly reduces the wear of the cylinder and the hose, prolongs their service life, reduces the maintenance cost and replacement frequency of equipment.
