Description
Technical Field
[0001] This invention relates to hose pump technology, and more specifically to a hose pump. Background Technology
[0002] Hose pumps belong to the category of peristaltic pumps. Peristaltic pumps are a type of rotary positive displacement pump. They are named for their working principle, which is similar to the digestive tract, which transports gaseous, solid, and liquid media in a peristaltic manner. The primary consideration for designers and users of hose pumps is their ability to transport highly abrasive media. They have no valves or seals, and the only part that comes into contact with the media is the inner cavity of the rubber hose. The rotor that compresses the hose is completely independent of the media.
[0003] Chinese patent CN209115304U discloses a hose pump, including an external base. The hose pump base extending to the outside of the external base is movably connected inside the external base. A motor base is fixedly connected to the top of the hose pump base, and a hose pump motor is fixedly installed on the top of the motor base, which solves the problem of inconvenience in moving the pump.
[0004] While existing flexible hose pumps can deliver media by squeezing the hose body with rollers in actual media pumping applications, meeting basic pumping requirements, the hose body is a vulnerable part that comes into direct contact with the media and needs to be disassembled and replaced regularly. However, the squeezing rollers of existing flexible hose pumps are mostly designed with a fixed structure, which keeps the hose body under constant compression and lacks an automatic release and reset structure. Replacement requires additional disassembly of the roller and related fixing components, which is cumbersome, consumes a lot of manpower and time, and significantly reduces the efficiency of hose replacement. Summary of the Invention

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0036] To address the issue that the compression rollers 393 in most hose pumps are designed with a fixed structure, constantly compressing the hose body 6 without an automatic release mechanism, replacement requires additional disassembly of the rollers 393 and related fixing components, resulting in cumbersome procedures and significant time and manpower consumption, please refer to [the relevant documentation / reference needed]. Figure 1 - Figure 13 The following preferred technical solutions are provided.
[0037] An embodiment of the present invention provides: a hose pump, including a base 1, a housing 2 provided at the upper end of the base 1, a first mounting groove 21 provided in the bottom wall of the inner wall of the housing 2, an output component 3 provided inside the housing 2, a sealing component 4 provided at one end of the housing 2, a drive component 5 provided at the upper end of the base 1, and a hose body 6 provided inside the housing 2.
[0038] Output component 3 includes a rotating shaft 31 movably connected to the inner wall of the first mounting slot 21. One end of the rotating shaft 31 is fixedly connected to a first rotating seat 32. A rotating disk 33 is disposed inside the first rotating seat 32. Two drive slots 331 are evenly opened on the side wall of the rotating disk 33. A first drive column 34 is movably connected to the inner wall of the drive slot 331. A drive cylinder 35 is fixedly connected to the center of one end of the rotating disk 33. A fixing component 36 is disposed on the outer wall of the drive cylinder 35. A first spring 37 is fixedly connected to the bottom wall of the inner wall of the drive cylinder 35. A second drive column 371 is fixedly connected to one end of the first spring 37. The second drive column 371 is located away from the first drive column 34. A second rotating seat 38 is fixedly connected to the side wall of one end of a rotating seat 32. A connecting rod 381 is movably connected inside the second rotating seat 38 via a pin. A third rotating seat 382 is movably connected to one end of the connecting rod 381. A push plate 383 is fixedly connected to one end of a first drive column 34. A second spring 39 is fixedly connected to the inner wall of the push plate 383. An extension plate 391 is fixedly connected to one end of the second spring 39. One end of the third rotating seat 382 is fixedly connected to the side wall of the extension plate 391. A mounting frame 392 is fixedly connected to the end of the extension plate 391 away from the second spring 39. A roller 393 is movably connected to the inner wall of the mounting frame 392.
[0039] Specifically, the drive assembly 5 drives the rotating shaft 31 of the output assembly 3, which in turn drives the first rotating seat 32 to rotate within the housing 2. The first rotating seat 32 drives the roller 393 through the push plate 383 to squeeze the hose 6 inside the housing 2, thereby realizing the pumping operation of the medium. When the hose 6 needs to be replaced, the sealing assembly 4 is first removed. The sealing assembly 4 stops squeezing the first spring 37. The first spring 37 pushes the second drive column 371 away from the first rotating seat 32. The second drive column 371 drives the connecting rod 381 to rotate around the third rotating seat 382 through the second rotating seat 38, thereby pulling the extension plate 391. At the same time, the second spring 39 pulls the extension plate 391, causing the roller to... The roller 393 moves closer to the first rotating seat 32 to reduce the pressure on the hose body 6, thus facilitating quick disassembly and replacement of the hose body 6. When it is necessary to adjust the pressure of the roller 393 on the hose body 6, the limiting position of the fixing component 36 is released first, and then the rotating block 372 at one end of the second drive column 371 drives the drive cylinder 35 to rotate. The drive cylinder 35 drives the rotating disk 33 to rotate synchronously, changing the relative position of the drive groove 331 and the first drive column 34, thereby adjusting the extent of the push plate 383 extending out of the first rotating seat 32, so as to adjust the pressure of the roller 393 on the hose body 6. After the adjustment is completed, the fixing component 36 is adjusted in the opposite direction to complete the fixing of the drive cylinder 35 and the first rotating seat 32.
[0040] The first rotating seat 32 has a plurality of second slots 324 evenly distributed at the end away from the rotating shaft 31. The fixing component 36 includes a fixing ring 361 threadedly connected to the outer wall of the drive cylinder 35. The fixing ring 361 has a second mounting groove 362 at one end. A plurality of third springs 363 are evenly fixedly connected to the bottom wall of the second mounting groove 362. A second connecting ring 364 is fixedly connected to one end of the third spring 363. A mounting ring 365 is fixedly connected to the end of the second connecting ring 364 away from the third spring 363. A plurality of locking blocks 366 are evenly fixedly connected to the end of the mounting ring 365 away from the second connecting ring 364. The locking blocks 366 engage with the second slots 324.
[0041] Specifically, after the squeezing force of the roller 393 on the hose body 6 is adjusted to the correct position, when it is necessary to fix the drive cylinder 35 and the first rotating seat 32 to maintain the adjusted state, rotate the fixing ring 361 threaded on the outer wall of the drive cylinder 35. When the fixing ring 361 moves along the axial direction of the drive cylinder 35, it will push multiple third springs 363 in its second mounting groove 362. The third springs 363 drive the second connecting ring 364 and the mounting ring 365 to move closer to the first rotating seat 32 through elastic force. This causes multiple locking blocks 366 at the end of the mounting ring 365 away from the second connecting ring 364 to simultaneously approach the second locking groove 324 opened at the end of the first rotating seat 32 away from the rotating shaft 31. Finally, the locking blocks 366 and the second locking groove 324 are precisely engaged. The engagement structure restricts the rotational freedom of the drive cylinder 35 relative to the first rotating seat 32, thereby achieving a stable fixation of the two and ensuring that the roller 393 always maintains the adjusted position, stably squeezing the hose body 6 to ensure the medium delivery effect.
[0042] The second drive column 371 is fixedly connected to a rotating block 372 at one end. The sealing assembly 4 includes a cover plate 41 disposed at one end of the housing 2. The bottom wall of the cover plate 41 is evenly provided with multiple third mounting grooves 42. A transparent plate 43 is fixedly connected to the inner wall of the third mounting groove 42. The cover plate 41 is evenly fixedly connected with multiple fixing plates 44 at one end. A first bolt 45 is threaded through the inside of the fixing plate 44. The bottom wall of the cover plate 41 is provided with a fourth mounting groove 46. The inner wall of the fourth mounting groove 46 is evenly provided with multiple first placement grooves 461. A ball bearing 47 is movably connected to the inner wall of the first placement groove 461. A fixing cylinder 48 is threadedly connected to the inner side wall of the fourth mounting groove 46. The top wall of the fixing cylinder 48 is evenly provided with multiple third through holes 481. A fixing groove 482 is provided at the center of the top wall of the fixing cylinder 48. A second bolt 483 is provided on the inner wall of the fixing groove 482.
[0043] Specifically, the cover plate 41 is fixed to the housing 2 by a first bolt 45 with a through thread, through a fixed plate 44 evenly arranged at one end, thereby sealing one end of the housing 2. Secondly, the transparent plate 43 fixed in the third mounting groove 42 on the inner bottom wall of the cover plate 41 allows the operator to easily observe the operation of the internal structure of the housing 2 and monitor the content of internal lubricating oil in real time. Secondly, the ball bearing 47 movably connected in the first placement groove 461 of the fourth mounting groove 46 on the inner bottom wall of the cover plate 41 abuts against the rotating block 372 at one end of the second drive column 371 during device operation, effectively reducing frictional loss when the rotating block 372 rotates by replacing sliding friction with rolling friction. Thirdly, the fixed cylinder 48 with a threaded connection on the inner side wall of the fourth mounting groove 46 is further reinforced by the second bolt 483 in the fixing groove 482 on its inner wall. When the ball bearing 47 wears, the second bolt 483 can be unscrewed and the fixed cylinder 48 can be unscrewed through the thread, realizing the quick disassembly and replacement of the fixed cylinder 48 and ensuring the stable auxiliary function of the sealing component 4.
[0044] The drive assembly 5 includes a first mounting base 51 and a second mounting base 55 fixedly connected to the upper surface of the base 1. A rotary drive component 52 is fixedly connected to the upper end of the first mounting base 51. A reducer 53 is fixedly connected to the output end of the rotary drive component 52. A coupling 54 is provided at one end of the reducer 53. One end of the coupling 54 is fixedly connected to the rotating shaft 31. The upper end of the second mounting base 55 is fixedly connected to the outer wall of the housing 2. In this embodiment, the rotary drive component 52 can be a motor.
[0045] Specifically, the first mounting seat 51 on the upper surface of the base 1 provides a stable mounting base for the rotary drive component 52, while the second mounting seat 55 is fixedly connected to the outer wall of the housing 2 to enhance the overall structural stability. When the rotary drive component 52 is started, its output power is first transmitted to the connected reducer 53. The reducer 53 adjusts the speed to ensure smooth power output. Then, the processed power is accurately transmitted to the rotating shaft 31 of the output component 3 through the coupling 54 at one end of the reducer 53, which finally drives the rotating shaft 31 to rotate stably, providing core power support for the subsequent compression of the hose body 6 by the roller 393 to achieve media pumping.
[0046] Both ends of the flexible tube 6 are fixedly connected with a third connecting ring 61. The outer wall of the housing 2 is provided with a first through hole 23 and a second through hole 24. One end of the housing 2 is provided with an inlet groove 25 and an outlet groove 26. The inner walls of the first through hole 23 and the second through hole 24 are fixedly connected with a first fixing tube 27. The outer wall of one end of the first fixing tube 27 is threadedly connected with a second fixing tube 29. The inner walls of the inlet groove 25 and the outlet groove 26 are respectively fixedly connected with infusion tubes 7. One end of the infusion tube 7 is provided with a valve 71. In this embodiment, the third connecting ring 61 is a rubber plate.
[0047] Specifically, the two ends of the hose body 6 are assembled and fixed to the housing 2 through the third connecting ring 61. The first through hole 23 and the second through hole 24 on the outer wall of the housing 2 are both fixed with the first fixing tube 27. During assembly, the two ends of the hose body 6 are aligned and fitted into the corresponding first fixing tube 27. Then, the second fixing tube 29, which is threaded to the outer wall of the first fixing tube 27, is rotated. The axial movement of the second fixing tube 29 squeezes the third connecting ring 61. The elastic deformation characteristics of the rubber plate are used to achieve the sealing and fixation of the hose body 6 and the first fixing tube 27. At the same time, the inlet groove 25 and the outlet groove 26 opened at one end of the housing 2 are respectively fixed with the infusion tube 7. The valve 71 at one end of the infusion tube 7 can control the opening and closing. The operator can open the valve 71 to inject lubricating oil into the housing 2 through the infusion tube 7 or discharge deteriorated old lubricating oil according to the operating requirements of the device, so as to ensure the lubrication effect of the internal components and ensure the stable operation of the hose pump.
[0048] The end of the first rotating seat 32 away from the fixed component 36 is fixedly connected to a limiting ring 221, and a limiting groove 22 is opened in the bottom wall of the housing 2, with the limiting ring 221 movably connected to the inner wall of the limiting groove 22.
[0049] Specifically, when the drive component 5 drives the rotating shaft 31 to rotate, the rotating shaft 31 will drive the first rotating seat 32 to rotate synchronously. At this time, the limiting ring 221 slides smoothly along the inner wall of the limiting groove 22. Through the circumferential limiting effect of the limiting groove 22 on the limiting ring 221, the radial displacement of the first rotating seat 32 during the rotation process is limited, avoiding it from shaking or tilting, thereby increasing the rotational stability of the first rotating seat 32 and ensuring the accuracy and continuity of the squeezing action of the roller 393 on the hose body 6 in the subsequent output component 3.
[0050] The first rotating seat 32 has a first rotating groove 321 at one end, a second rotating groove 322 on the bottom wall of the first rotating groove 321, and a sliding groove 323 on the side wall of the first rotating seat 32. The sliding groove 323, the second rotating groove 322 and the first rotating groove 321 are connected. The drive cylinder 35 is movably connected to the inner wall of the first rotating groove 321. The rotating disk 33 is movably connected to the inner wall of the second rotating groove 322. The push plate 383 is slidably connected to the inner wall of the sliding groove 323.
[0051] Specifically, the first rotating seat 32 has a first rotating groove 321 at one end, and a second rotating groove 322 is correspondingly provided on its inner bottom wall. The side wall of the first rotating seat 32 has a sliding groove 323 that communicates with the former two, together forming a continuous installation and movement space. The drive cylinder 35 of the output component 3 is adapted to be installed in the first rotating groove 321 and can move flexibly. The rotating disk 33 is correspondingly embedded in the second rotating groove 322, and the push plate 383 forms a sliding fit with the sliding groove 323 to realize the assembly of each core component.
[0052] A retaining ring 62 is fixedly connected to the side wall of the third connecting ring 61. A first retaining groove 28 is opened at one end of the first fixing tube 27. The retaining ring 62 engages with the first retaining groove 28. When assembling the hose body 6, the third connecting rings 61 at both ends are first aligned and sleeved onto the corresponding first fixing tubes 27, so that the retaining ring 62 is precisely embedded in the first retaining groove 28 to form a locking fit. Through the interlocking relationship between the retaining ring 62 and the first retaining groove 28, the axial movement and radial displacement of the hose body 6 relative to the first fixing tube 27 are restricted. Subsequently, the second fixing tube 29, which is threaded to the outer wall of the first fixing tube 27, is used to squeeze and fix the third connecting ring 61. With double protection, the installation stability of the hose body 6 and the first fixing tube 27 is increased, avoiding leakage problems caused by the loosening of the hose body 6 during the medium pumping process, and ensuring the continuity and reliability of the conveying operation.
[0053] The inner wall of the housing 2 is provided with a second placement groove 63. When the hose body 6 is assembled, its main body is embedded in the second placement groove 63. Combined with the locking structure of the two ends of the hose body 6 with the first fixing tube 27 through the third connecting ring 61 and the retaining ring 62, a dual positioning mode of "fixed at both ends + limited in the middle" is formed. When the roller 393 of the output component 3 squeezes and pumps the hose body 6, the second placement groove 63 limits the lateral movement of the hose body 6 through the groove wall, preventing radial displacement, twisting or separation from the preset position during the squeezing process. This ensures that the roller 393 always maintains precise squeezing contact with the hose body 6, thereby increasing the stability of the placement of the hose body 6, ensuring the continuity and reliability of the medium transportation, and reducing local excessive wear caused by force deviation of the hose body 6, thus extending its service life.
[0054] One end of the cover plate 41 has an abutment groove 49, and one end of the housing 2 is fixedly connected to a first connecting ring 201. A rubber ring 202 is fixedly connected to one end of the first connecting ring 201. The first connecting ring 201 engages with the abutment groove 49. During assembly, the abutment groove 49 at one end of the cover plate 41 is aligned with the first connecting ring 201 fixed at one end of the housing 2, so that the two are precisely engaged. The engagement structure achieves the initial positioning of the cover plate 41 and the housing 2. Then, the first bolt 45, which passes through the fixing plate 44 on the cover plate 41, is used to lock and reinforce it, forming a "lock". The dual connection mode of "positioning + bolt fixing" effectively limits the displacement of the cover plate 41 relative to the housing 2, improving the stability of the connection between the two. Secondly, the rubber ring 202 fixed at one end of the first connecting ring 201 is squeezed by the inner wall of the abutment groove 49 during the engagement process and undergoes elastic deformation, tightly filling the tiny gap between the abutment groove 49 and the first connecting ring 201, blocking the communication channel between the inside of the housing 2 and the external environment, preventing internal lubricating oil leakage, thereby ensuring the sealing performance of the connection between the cover plate 41 and the housing 2, and providing protection for the stable operation of the hose pump.
