Description

Technical Field

[0001] This utility model relates to the field of pump tube kit technology, and in particular to a peristaltic pump tube kit. Background Technology

[0002] A peristaltic pump is a type of pump that delivers fluid by squeezing a hose with rollers. This type of pump is characterized by its ability to gently deliver fluids with minimal shear force. Peristaltic pumps are widely used for delivering viscous fluids.

[0003] A peristaltic pump generally consists of a pump body housing, rollers, a motor, pump tubing, an inlet flange, an outlet flange, an inlet pump tubing assembly, and an outlet pump tubing assembly. The rollers, motor, and pump tubing are housed inside the pump body housing. The two ends of the pump tubing are connected to the inlet flange and the outlet flange, respectively. The inlet pump tubing assembly is then connected and fixed to the inlet flange, and the outlet pump tubing assembly is connected and fixed to the outlet flange.

[0004] In practical use, the viscous liquid delivered by the inlet pump tube assembly enters the pump tube. The motor drives the rollers to squeeze the pump tube, squeezing the viscous liquid in the pump tube. The viscous liquid is pushed to the outlet flange and finally delivered through the outlet pump tube assembly.

[0005] Currently, existing peristaltic pumps have poor sealing at the connection points between the inlet pump tubing and the inlet flange on the pump body casing. At the same time, the sealing at the connection points between the outlet pump tubing and the outlet flange is also poor, which easily leads to leakage and thus affects the normal fluid delivery of the peristaltic pump.

[0006] In addition, the existing peristaltic pumps have relatively low overall structural stability in both the inlet and outlet pump tubing assemblies.

[0007] The above problems are widespread and urgently need to be improved. Utility Model Content

[0008] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing a peristaltic pump tubing kit.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A peristaltic pump tubing assembly is designed, including an inlet pump tubing assembly and an outlet pump tubing assembly. A pump body housing is located on the right side of both the inlet and outlet pump tubing assemblies. A base is located at the bottom of the pump body housing, and a motor is mounted on the base. An inlet flange and an outlet flange are provided on the pump body housing. The inlet flange has a first threaded groove, and the outlet flange has a second threaded groove. A first connecting cover is provided on the inlet pump tubing assembly, and a second connecting cover is provided on the outlet pump tubing assembly. The first connecting cover has a first countersunk hole, and the second connecting cover has a second countersunk hole. Sealing ring gaskets are provided on the inner walls of both the first and second connecting covers.

[0011] Furthermore, the outer walls of both the inlet pump tubing assembly and the outlet pump tubing assembly are provided with reinforcing ribs. The reinforcing ribs are made of hard alloy tungsten steel and are four in number arranged in a circle with a thickness of six to eight millimeters.

[0012] Furthermore, both the first and second connecting covers are annular structures with hollow cavities inside, and both are made of stainless steel.

[0013] Furthermore, the lateral thickness of the sealing ring gasket is not less than the thickness of the inlet flange and the outlet flange.

[0014] Furthermore, the first threaded groove and the first countersunk hole form a group and there are a total of six groups arranged in a circle, and the second threaded groove and the second countersunk hole form a group and there are a total of six groups arranged in a circle. The inner walls of the first countersunk hole and the second countersunk hole are provided with damping sealing rings, and the damping sealing rings are made of elastic damping silicone material.

[0015] Furthermore, both the first countersunk hole and the second countersunk hole are countersunk groove structures that penetrate the sealing collar gasket.

[0016] Furthermore, the sealing collar gaskets are respectively disposed on the inner wall surfaces of the first connecting cover and the second connecting cover, and the sealing collar gaskets are made of NBR nitrile rubber.

[0017] The peristaltic pump tubing kit proposed in this utility model has the following advantages:

[0018] 1. This utility model improves the overall sealing performance of the peristaltic pump by setting a sleeve-type first connecting cover on the inlet pump tube assembly and a sleeve-type second connecting cover on the outlet pump tube assembly, and by providing a sealing collar gasket structure on the inner wall of both the first and second connecting covers. This prevents leakage and ensures the normal liquid delivery of the peristaltic pump.

[0019] 2. This utility model improves the overall structural stability of the inlet pump tube assembly and the outlet pump tube assembly by setting reinforcing rib structures on both.

[0020] 3. This utility model improves the sealing performance of the preset screw installation part by opening a first countersunk hole on the first connecting cover and a second countersunk hole on the second connecting cover, and setting a damping sealing ring structure in the first countersunk hole and the second countersunk hole, while avoiding the screw cap of the preset screw from being exposed and affecting the aesthetics.

Detailed Implementation

[0027] 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.

[0028] Reference Figure 1-5A peristaltic pump tubing assembly includes an inlet pump tubing assembly 4 and an outlet pump tubing assembly 6. A pump body housing 1 is located on the right side of both the inlet and outlet pump tubing assemblies 4 and 6. A base 11 is located at the bottom of the pump body housing 1, and a motor 12 is mounted on the base 11. An inlet flange 2 and an outlet flange 3 are mounted on the pump body housing 1. The inlet flange 2 has a first threaded groove 21, and the outlet flange 3 has a second threaded groove 31. The inlet pump tubing assembly 4 has a first connecting cover 5, and the outlet pump tubing assembly 6 has a second connecting cover 7. The first connecting cover 5 has a first countersunk hole 51, and the second connecting cover 7 has a second countersunk hole 71. Sealing ring gaskets 9 are provided on the inner walls of both the first and second connecting covers 5 and 7. The pump body housing 1, base 11, motor 12, inlet flange 2, and outlet flange 3 described in this patent are all related structures of a peristaltic pump and are existing technologies. Some existing structures are not shown and need not be described further.

[0029] In detail, the outer walls of both the inlet pump tubing assembly 4 and the outlet pump tubing assembly 6 are provided with reinforcing ribs 8. The reinforcing ribs 8 are made of hard alloy tungsten steel. There are four reinforcing ribs 8 arranged in a circle and the thickness is six to eight millimeters. Hard alloy tungsten steel has high strength, does not deform, and is corrosion-resistant and durable.

[0030] Furthermore, the first connecting cover 5 and the second connecting cover 7 are annular structures with hollow cavities inside. Both the first connecting cover 5 and the second connecting cover 7 are made of stainless steel, which is strong and impact-resistant, can achieve a sealing effect, and improves the protection of the liquid inlet flange 2 and the liquid outlet flange 3.

[0031] Furthermore, the lateral thickness of the sealing ring gasket 9 is not less than the thickness of the inlet flange 2 and the outlet flange 3, ensuring that the sealing ring gasket 9 fully compresses and seals the outer wall surfaces of the inlet flange 2 and the outlet flange 3.

[0032] More specifically, the first threaded groove 21 and the first countersunk hole 51 form a group and there are a total of six groups arranged in a circle, and the second threaded groove 31 and the second countersunk hole 71 form a group and there are a total of six groups arranged in a circle, which respectively improves the connection stability between the first connecting cover 5 and the liquid inlet flange 2 and between the second connecting cover 7 and the liquid outlet flange 3.

[0033] The inner walls of the first countersunk hole 51 and the second countersunk hole 71 are both provided with damping sealing rings 511. The damping sealing rings 511 are made of elastic damping silicone material, which has elastic sealing properties, is resistant to high and low temperatures, has stable chemical properties, and is environmentally friendly and insulating.

[0034] In summary, both the first countersunk hole 51 and the second countersunk hole 71 are countersunk groove structures that pass through the sealing collar gasket 511, so that the preset internal hex screw can smoothly pass through the sealing collar gasket 511 for later thread locking.

[0035] Finally, the sealing ring gaskets 9 are respectively set on the inner wall surfaces of the first connecting cover 5 and the second connecting cover 7. The sealing ring gaskets 9 are made of NBR nitrile rubber, which has excellent elastic sealing properties and is oil-resistant, anti-aging, and heat-resistant.

[0036] Operating method: During installation, taking the inlet pump tube assembly 4 as an example, the first connecting cover 5 on the inlet pump tube assembly 4 is attached to the inlet flange 2. Then, six Allen screws are passed through the first countersunk hole 51, and then the Allen screws are threaded and locked to the first threaded groove 21 using an Allen wrench. At this time, the sealing ring gasket 9 on the inner wall of the first connecting cover 5 will effectively squeeze and seal against the outer wall of the inlet flange 2. Similarly, the outlet pump tube assembly 6 can also be sealed and locked to the outlet flange 3 through the second connecting cover 7. This improves the overall sealing performance between the inlet pump tube assembly 4 and the inlet flange 2, and between the outlet pump tube assembly 6 and the outlet flange 3 on the peristaltic pump, avoiding leakage and ensuring the normal liquid delivery of the peristaltic pump.

[0037] Furthermore, by providing reinforcing ribs 8 on both the inlet pump tube assembly 4 and the outlet pump tube assembly 6, the overall structural stability of the inlet pump tube assembly 4 and the outlet pump tube assembly 6 is improved.

[0038] In addition, by opening a first countersunk hole 51 on the first connecting cover 5 and a second countersunk hole 71 on the second connecting cover 7, and by setting a damping sealing ring 511 structure in the first countersunk hole 51 and the second countersunk hole 71, the sealing performance of the preset screw installation part is further improved, while avoiding the screw cap of the preset screw from being exposed and affecting the aesthetics.

[0039] 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.
