Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and more specifically, to a small-volume, high-flow, quick-install peristaltic pump. Background Technology

[0002] A peristaltic pump is a device used to transport fluids, mainly composed of a driver, a pump head, and a flexible hose. Its working principle involves rollers alternately squeezing and releasing the flexible hose to pump fluid. However, peristaltic pumps are often installed using screws. When periodically disassembling the pump for cleaning and maintenance of its internal components, these screws need to be removed and reassembled. This process is not only complex for users, but the repeated removal and reassembly of the screws can also cause deformation of the threads. The accumulated deformation reduces the frictional area between the threads, decreasing friction and making effective locking impossible. This reduces the safety of the peristaltic pump and significantly shortens its lifespan. Therefore, we propose a small-volume, high-flow, quick-installation peristaltic pump to solve these problems. Utility Model Content

[0003] The main objective of this invention is to provide a small-volume, high-flow, quick-install peristaltic pump. This solves the problem that when a peristaltic pump needs to be disassembled periodically for cleaning and maintenance of its internal components, screws need to be removed and reassembled. However, this process is not only complicated for users, but the threads also deform during repeated disassembly and reassembly. The cumulative deformation after repeated disassembly and reassembly reduces the frictional area between the threads, thus reducing the frictional force and making it impossible to effectively lock the pump. This reduces the safety of the peristaltic pump and greatly shortens its service life.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A small-volume, high-flow, quick-install peristaltic pump includes a base. A working pump cover is snapped onto the upper end of the base, and a locking pump cover is snapped onto the upper end of the working pump cover. An internal tube is installed between the working pump cover and the base. A wheel frame is movably installed between the working pump cover and the base. The wheel frame is movably installed at the bend of the internal tube. Several rollers are movably installed on the outer side of the wheel frame, and the rollers are in contact with the outer side of the internal tube. A stepper motor is installed at the lower end of the base, and the output end of the stepper motor is movably installed inside the base and connected to the wheel frame.

[0006] Preferably, the lower surface of the locking pump cover is equipped with several locking blocks, and the upper surface of the base is equipped with a guide frame at both the front and rear ends. The upper ends of the guide frames are respectively engaged between the working pump cover and the locking pump cover, and the locking blocks are engaged with the guide frames.

[0007] Preferably, the working pump cover has two guide frames at both ends of its front surface, and the built-in tubes are respectively engaged and installed inside the two guide frames. The two ends of the built-in tubes are respectively fitted with pipe clamps, and the pipe clamps are respectively engaged and installed inside the two guide frames.

[0008] Preferably, an auxiliary rod is installed on the lower surface of the working pump cover, the lower end of the auxiliary rod is engaged inside the wheel frame, and a bearing is installed between the working pump cover and the wheel frame.

[0009] Preferably, a splined shaft is movably mounted inside the base, with the upper end of the splined shaft engaging with the lower end of the wheel frame, and the output end of the stepper motor mounted inside the splined shaft.

[0010] Preferably, small shafts are installed through the interior of each roller, and the small shafts are respectively engaged and installed inside the wheel frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) In this utility model, the working pump cover and the base are first snapped together, and then the user installs the locking pump cover, so that the locking pump cover and the working pump cover are snapped together with the guide frame to complete the overall assembly. There is no need to connect with screws, which can improve the overall disassembly and assembly efficiency and extend the overall service life. At the same time, it can also reduce the space required for peristaltic pump maintenance, making it easier for peristaltic pump to be disassembled and assembled in various narrow positions, and making it easier to use.

[0013] (2) In this utility model, the guide frame guides the base and the working pump cover, allowing the working pump cover to move straight up and down, thus avoiding positional misalignment between the working pump cover and the base. When the working pump cover moves, it drives the wheel frame to move. When the wheel frame moves down, the wheel frame and the spline shaft will automatically rotate and align, assisting in the overall installation. Finally, the base, the working pump cover and the locking pump cover are engaged to achieve the overall installation, which is more convenient. Attached Figure Description

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a small-volume, high-flow, quick-install peristaltic pump, including a base 9, a working pump cover 2 that is snapped onto the upper end of the base 9, a locking pump cover 1 that is snapped onto the upper end of the working pump cover 2, an internal tube 7 installed between the working pump cover 2 and the base 9, a wheel frame 4 that is movably installed between the working pump cover 2 and the base 9, the wheel frame 4 being movably installed at the bend of the internal tube 7, a plurality of rollers 6 that are movably installed on the outer side of the wheel frame 4, the rollers 6 being in contact with the outer side of the internal tube 7, and a stepper motor 11 that is installed at the lower end of the base 9, the output end of the stepper motor 11 being movably installed through the interior of the base 9 and connected to the wheel frame 4.

[0021] like Figure 1 To Figure 4As shown, in another embodiment of this utility model, a plurality of locking blocks 12 are installed on the lower surface of the locking pump cover 1, and a first guide frame 13 is installed at both the front and rear ends of the upper surface of the base 9. The upper ends of the first guide frame 13 are respectively engaged between the working pump cover 2 and the locking pump cover 1, and the locking blocks 12 are engaged with the first guide frame 13. A second guide frame 14 is provided at both ends of the front surface of the working pump cover 2, and the internal tube 7 is respectively engaged inside the second guide frame 14. A tube clamp 8 is installed at both ends of the internal tube 7. Card 8 is respectively engaged and installed inside the second guide frame 14. An auxiliary rod 15 is installed on the lower surface of the working pump cover 2. The lower end of the auxiliary rod 15 is engaged and installed inside the wheel frame 4. A bearing 3 is installed between the working pump cover 2 and the wheel frame 4. A spline shaft 10 is movably installed inside the base 9. The upper end of the spline shaft 10 is engaged and installed inside the lower end of the wheel frame 4. The output end of the stepper motor 11 is installed inside the spline shaft 10. Small shafts 5 are respectively installed through the inside of the rollers 6. The small shafts 5 are respectively engaged and installed inside the wheel frame 4.

[0022] The user first assembles the stepper motor 11 with the base 9, then locks and positions it using cross-head screws. Next, the user assembles the splined shaft 10 with the output end of the stepper motor 11, forming a single unit. Then, the user presses and fastens the locking pump cover 1 along the corresponding notch on the working pump cover 2, and rotates the working pump cover 2 to the leftmost position, thus forming a combined pump cover. The user then installs the roller 6 onto the wheel frame 4 using the small shaft 5. After the roller 6 and small shaft 5 are installed, the wheel frame 4 and working pump cover 2 are then installed using the bearing 3 and auxiliary rod 15. Finally, the user attaches the pipe clamp 8 and... The user first quietly places the inner tube 7 onto the outside of the roller 6, and then controls the pipe clamp 8 to be installed inside the second guide frame 14 to install the inner tube 7 and the pipe clamp 8. Then, the user controls the working pump cover 2 to move down along the first guide frame 13, so that the working pump cover 2 and the base 9 become one.

Then, the user can pull the working pump cover 2 along the first guide frame 13 by locking the pump cover 1, so that the working pump cover 2 can move the internal tube 7 and the wheel frame 4. Then, the user can repair or replace the internal tube 7 or the wheel frame 4, which is simpler and faster.

Then, the user presses and fastens the locking pump cover 1 along the corresponding notch on the working pump cover 2, and rotates the working pump cover 2 to the leftmost position, thus forming a combined pump cover. The user then installs the roller 6 onto the wheel frame 4 using the small shaft 5. After the roller 6 and small shaft 5 are installed, the wheel frame 4 and working pump cover 2 are then installed using the bearing 3 and auxiliary rod 15. Finally, the user inserts the pipe...
