Description

Technical Field

[0001] The utility model relates to the technical field of hose pumps, and specifically relates to a boot mechanism for a hose pump that is convenient for disassembly and assembly. Background Art

[0002] A hose pump belongs to the category of peristaltic pumps. A peristaltic pump is a type of rotary displacement pump. It gets its name because its working principle is similar to the way the digestive tract transports gas, solid, and liquid three-phase media by peristalsis. The designers and users of hose pumps primarily value its ability to transport highly abrasive media. It has no valves and no seals. The only component in contact with the medium is the inner cavity of the rubber hose. The rotor that compresses the hose is completely independent of the medium. The unique feature of a hose pump is that no other pump type has a better self-priming ability than a hose pump. It can almost generate a perfect vacuum to suck liquid, transport gas-containing liquid and foam liquid without air blockage, and is also strong in transporting high-viscosity and shear-sensitive media. It has a fixed displacement per revolution regardless of the outlet pressure and is a natural metering pump.

[0003] However, currently, the boot mechanism composed of a turntable and a convex body in a hose pump cannot be disassembled conveniently, which is inconvenient for disassembling the boot mechanism after the hose pump is used and during subsequent maintenance of the hose pump. At the same time, when the hose pump is not in use, the long-term extrusion of the hose by the boot mechanism will also affect the service life of the hose.

[0004] Based on this, a boot mechanism for a hose pump that is convenient for disassembly and assembly is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

[0005] The purpose of the utility model is to provide a boot mechanism for a hose pump that is convenient for disassembly and assembly to solve the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A boot mechanism for a hose pump that is convenient for disassembly and assembly includes a turntable. The turntable is arranged inside the inner cavity of the hose pump. A rotating shaft is fixedly connected in the middle of the turntable. An assembly and disassembly component that is convenient for the disassembly and assembly of the boot mechanism is arranged between the rotating shaft and the output end of the motor.

[0008] Based on the above technical solutions, the utility model also provides the following optional technical solutions:

[0009] In an optional solution: Two clamping blocks are arranged on the side of the turntable. A rotating rod is rotatably connected between the two clamping blocks. A convex body is fixedly connected to the periphery of the rotating rod.

[0010] In an optional solution: The convex body is in the shape of a cylinder.

[0011] In an alternative solution: The disassembly component includes a sleeve column. There are two sleeve columns, namely the active sleeve column and the driven sleeve column. The driven sleeve column is sleeved around the outer periphery of the rotating shaft, and the active sleeve column is sleeved around the outer periphery of the motor output end.

[0012] In an alternative solution: A fixing disk is provided at one opposite end of the active sleeve column and the driven sleeve column, and a plurality of fixing holes are provided on the fixing disk.

[0013] In an alternative solution: A plurality of grooves are formed at the bottom end of the fixing disk at one end of the active sleeve column, and a plurality of protrusions are formed at the bottom end of the fixing disk at one end of the driven sleeve column. The grooves and the protrusions are matched with each other.

[0014] In an alternative solution: A rubber sleeve is fixedly provided on the outer side of the protrusion.

[0015] In an alternative solution: A matching bolt is provided on the fixing hole.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By providing the disassembly and assembly component, the present utility model enables the press shoe mechanism composed of the turntable and the convex body to be conveniently installed and disassembled with the motor output end in the hose pump, achieving the effect of facilitating the disassembly and assembly of the press shoe mechanism. After the hose pump is used, the press shoe mechanism can be disassembled to reduce the frictional damage to the hose, prolonging the service life of the hose. At the same time, it also facilitates the disassembly of the press shoe mechanism and the motor during subsequent maintenance.

Detailed implementation mode

[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, as Figures 1 - 4 shown, a boot pressing mechanism for a hose pump that is convenient for disassembly and assembly includes a turntable 100, the turntable 100 is arranged inside the hose pump cavity, a rotating shaft 101 is fixedly connected in the middle of the turntable 100, and a disassembly and assembly component 200 for facilitating the disassembly and assembly of the boot pressing mechanism is arranged between the rotating shaft 101 and the output end of the motor;

[0026] During use, by starting the motor, the output end of the motor drives the rotating shaft 101 to rotate, thereby driving the turntable 100 to rotate, so that the hose pump starts to work. Arranging the disassembly and assembly component 200 between the rotating shaft 101 and the output end of the motor can facilitate the disassembly and assembly of the boot pressing mechanism composed of the turntable 100 and the convex body 102, which is convenient for later maintenance and protection of the hose, and improves the service life of the hose and the flexibility between the hose pump components.

[0027] In one embodiment, as Figure 1 shown, two clamping blocks 103 are arranged on the side of the turntable 100, a rotating rod 104 is rotatably connected between the two clamping blocks 103, and a convex body 102 is fixedly connected to the periphery of the rotating rod 104;

[0028] During use, the clamping blocks 103 can play a limiting role on the convex body 102. At the same time, a rotating rod 104 is rotatably connected between the clamping blocks 103, and the convex body 102 is fixedly connected to the rotating rod 104. When the hose pump is working, the turntable 100 drives the convex body 102 to rotate to squeeze the hose. At the same time, when the convex body 102 squeezes the hose, the convex body 102 will also rotate between the clamping blocks 103 along with the rotating rod 104, playing a moving extrusion effect on the hose, making the fluid flow and transportation effect in the hose better.

[0029] In one embodiment, as Figure 1 shown, the convex body 102 is in a cylindrical shape;

[0030] During use, the convex body 102 is in a cylindrical shape, which facilitates the rotation of the convex body 102 between the clamping blocks 103 following the rotating rod 104. At the same time, the cylindrical convex body 102 is more adaptable to the surface of the hose when moving and extruding the hose, making the effect of the hose pump better. At the same time, the cylindrical convex body 102 can also reduce the wear on the hose and increase the service life of the hose.

[0031] In one embodiment, as Figure 2 and Figure 3 shown, the disassembly component 200 includes a sleeve column 201. There are two sleeve columns 201. The two sleeve columns 201 are respectively a driving sleeve column and a driven sleeve column. The driven sleeve column is sleeved around the outer periphery of the rotating shaft 101, and the driving sleeve column is sleeved around the outer periphery of the motor output end;

[0032] During use, the sleeve column 201 can facilitate the installation of the disassembly and assembly component 200 on the rotating shaft 101 and the motor output end. Align the driving sleeve column with the motor output end and insert it so that the driving sleeve column is sleeved on the motor output end. Similarly, sleeve the driven sleeve column on the rotating shaft 101, and then subsequent installation can be carried out. When the hose pump is in use, if the motor and the pressure boot mechanism need to be replaced, it only needs to sleeve the sleeve column 201 on the new motor or the rotating shaft 101, without the need to re-produce the disassembly component 200, saving costs and facilitating subsequent installation and replacement.

[0033] In one embodiment, as Figure 3 shown, a fixing plate 202 is provided at the opposite ends of the driving sleeve column and the driven sleeve column. A plurality of fixing holes 203 are provided on the fixing plate 202;

[0034] During use, the fixing plate 202 at the opposite ends of the two sleeve columns 201 can be used to install the motor output end and the rotating shaft 101 on the pressure boot structure. The fixing holes 203 on the fixing plate 202 facilitate subsequent installation and disassembly.

[0035] In one embodiment, as Figure 3 and Figure 4 shown, a plurality of grooves 204 are provided at the bottom end of the fixing plate 202 at one end of the driving sleeve column, and a plurality of protrusions 205 are provided at the bottom end of the fixing plate 202 at one end of the driven sleeve column. The grooves 204 and the protrusions 205 are matched;

[0036] During use, insert the protrusions 205 on the fixing plate 202 at one end of the driven sleeve column into the grooves 204 on the fixing plate 202 at one end of the driving sleeve column to complete the splicing of the two fixing plates 202, and then fix the two fixing plates 202 through the fixing holes 203 on the fixing plate 202.

[0037] In one embodiment, as Figure 4As shown, a rubber sleeve 206 is fixedly provided on the outside of the bump 205;

[0038] During use, a rubber sleeve 206 is provided on the outside of the bump 205, which can improve the splicing stability between the two fixing plates 202 after the bump 205 is inserted into the groove 204, so that the fixing plates 202 will not be displaced after splicing, ensuring the stability of the subsequent rotation of the shaft 101 driven by the motor.

[0039] In one embodiment, as Figure 2 shown, a matching bolt 207 is provided on the fixing hole 203;

[0040] During use, after the two fixing plates 202 are spliced, the bolt 207 is used to fix the two fixing plates 202 through the fixing holes 203 on the fixing plates 202, completing the fixed installation between the motor output end and the shaft 101. When disassembly is required later, only need to unscrew the bolt 207 from the fixing hole 203, and then pull the two fixing plates 202 apart to complete the disassembly of the press shoe mechanism, simplifying the disassembly and assembly process and facilitating the installation and disassembly of the press shoe mechanism composed of the turntable 100 and the convex body 102.

[0041] The working principle of the present utility model is as follows: During use, the sleeve column 201 facilitates the disassembly and assembly of the component 200 on the rotating shaft 101 and the motor output end. First, align the active sleeve column with the motor output end and insert it so that the active sleeve column is sleeved on the motor output end. Similarly, sleeve the driven sleeve column on the rotating shaft 101. Then, insert the protrusion 205 on the fixed disk 202 at one end of the driven sleeve column into the groove 204 on the fixed disk 202 at one end of the active sleeve column to complete the splicing of the two fixed disks 202. A rubber sleeve 206 is provided on the outer side of the protrusion 205, which can improve the splicing stability between the two fixed disks 202 after the protrusion 205 is inserted into the groove 204, preventing displacement of the fixed disks 202 after splicing and ensuring the stability of the subsequent rotation of the rotating shaft 101 driven by the motor. After the two fixed disks 202 are spliced, use the bolt member 207 to fix the two fixed disks 202 through the fixing holes 203 on the fixed disks 202, completing the fixed installation between the motor output end and the rotating shaft 101. When disassembly is required later, simply unscrew the bolt member 207 from the fixing hole 203 and then pull apart the two fixed disks 202 to complete the disassembly of the pressing shoe mechanism, simplifying the disassembly and assembly process and facilitating the installation and disassembly of the pressing shoe mechanism composed of the turntable 100 and the convex body 102. After installation is completed, start the motor. The motor output end will drive the rotating shaft 101 to rotate, thereby driving the turntable 100 to rotate and making the hose pump start working. Clamping blocks 103 are provided on both sides of the turntable 100. The clamping blocks 103 can limit the convex body 102. At the same time, a rotating rod 104 is rotatably connected between the clamping blocks 103, and the convex body 102 is fixedly connected to the rotating rod 104. When the hose pump is working, the turntable 100 drives the convex body 102 to rotate and squeeze the hose. At the same time, when the convex body 102 squeezes the hose, the convex body 102 will also rotate between the clamping blocks 103 following the rotating rod 104, achieving a moving and squeezing effect on the hose and making the fluid flow and transportation effect in the hose better.

[0042] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
