Description

Technical Field

[0001] The present invention belongs to the technical field of peristaltic pumps, and particularly relates to a structure for preventing the loosening of a peristaltic pump tube. Background Art

[0002] A peristaltic pump is a positive displacement pump that realizes fluid transmission based on the periodic compression of an elastic hose. Its core principle is to form a vacuum chamber by squeezing the hose with rollers or sliders, pushing the liquid to flow unidirectionally. The flow rate is only related to the inner diameter of the hose, the rotational speed of the rollers, and the compression frequency, and has nothing to do with the outlet pressure. It has the advantages of being pollution-free (the fluid only contacts the hose), having strong self-priming ability (up to 9 meters), being able to handle high-viscosity (1 million cP) and particulate-containing (≤1 mm) media, and having high flow accuracy (±0.5% - 5%). It is widely used in medical fields (such as hemodialysis, drug injection), food fields (such as sauce filling, juice transportation), chemical industries (such as strong acid and strong base metering), environmental protection (such as wastewater sampling), etc. However, it should be noted that the hose life (usually 500 - 2000 hours) is affected by rotational speed, medium corrosiveness, and temperature, and needs to be replaced regularly to maintain performance. Its modular design supports rapid disassembly and multi-channel expansion, and is an ideal choice for small and medium flow rates, high cleanliness, and shear-sensitive fluid transmission scenarios.

[0003] Existing peristaltic pumps do not have the function of preventing the pipe from loosening during actual use. Since the peristaltic pump generates large vibrations during operation, the long-term continuous vibrations are extremely likely to cause the pipe to loosen from the peristaltic pump, which is not conducive to the use by staff. We propose a structure for preventing the loosening of a peristaltic pump tube. Summary of the Invention

[0004] The purpose of the present invention is to provide a structure for preventing the loosening of a peristaltic pump tube to solve the problems raised in the above background art.

An installation plate is provided at the bottom of the peristaltic pump main body. A chute is opened at the top of the installation plate. Three correspondingly distributed self-locking sliders are slidably installed inside the chute. First support blocks, second support blocks, and a connection block are respectively fixedly connected to the tops of the three self-locking sliders. Rubber pads are fixedly connected to the tops of the first support block and the second support block. Both rubber pads are adapted to the peristaltic pump main body; A circular shell is fixedly connected to the top of the connection block. A motor is provided outside the circular shell. The output end of the motor is fixedly connected to a rotating shaft. The rotating shaft extends into the circular shell. A plurality of moving blocks are provided inside the circular shell. A plurality of the moving blocks all slide and extend outside the circular shell. A plurality of circumferentially distributed threaded sleeves are rotatably installed on the inner wall of the circular shell. An arc-shaped plate is fixedly connected to one side of each of the plurality of moving blocks; A housing, the housing is arranged at the bottom of the mounting plate, both sides of the inner wall of the housing are fixedly connected with first damping pads, and the same slide bar is fixedly connected between the two first damping pads. Two symmetrically distributed first sliding blocks are slidably mounted on the outer part of the slide bar; A rotating assembly, the rotating assembly is arranged inside the circular housing and is used to drive a plurality of threaded sleeves to rotate simultaneously; A moving assembly, the moving assembly is arranged on the tops of the two first sliding blocks and is used to move the two first sliding blocks.

[0006] In this technical solution, through the provided pipe clamp, the pipeline on the peristaltic pump body can be fixed, avoiding the phenomenon that the pipeline becomes loose from the peristaltic pump body.

[0007] Move the circular housing to the outside of the peristaltic pump body. By starting the motor, drive the rotating shaft and the driving gear to rotate. Since the driving gear is meshed with the toothed disc, the toothed disc can be driven to move in a circular motion. Since the toothed disc is meshed with a plurality of driven gears, a plurality of driven gears can be driven to rotate simultaneously, and then drive a plurality of threaded rods, moving blocks and arc-shaped plates to move. At this time, the arc-shaped plate can clamp and fix the peristaltic pump body. Through the above-mentioned structures provided, the peristaltic pump body can be installed on the mounting plate.

Through the provided second rotating frame and the second connecting rod, the four second sliding blocks can be driven to move simultaneously. The second sliding block will squeeze the second spring to generate a squeezing force, which is transmitted to the second damping pad for absorption, and the peristaltic pump body can be shock-absorbed for the second time. The shock-absorbing effect is better. Through the above-mentioned structures provided, the vibration generated when the peristaltic pump body works can be shock-absorbed, the noise is reduced, the service life is prolonged and the operation stability is improved.

[0034] Embodiment 1: This embodiment provides a structure for preventing the peristaltic pump tube from loosening, including a peristaltic pump body 1. A mounting plate 3 is provided at the bottom of the peristaltic pump body 1. A chute 4 is opened at the top of the mounting plate 3. Three correspondingly distributed self-locking sliders 5 are slidably installed inside the chute 4. The tops of the three self-locking sliders 5 are respectively fixedly connected to a first support block 6, a second support block 7 and a connecting block 8. Rubber pads 9 are fixedly connected to the tops of the first support block 6 and the second support block 7, and both rubber pads 9 are adapted to the peristaltic pump body 1; A circular shell 10 is fixedly connected to the top of the connecting block 8. A motor 12 is provided outside the circular shell 10. The output end of the motor 12 is fixedly connected to a rotating shaft 13. The rotating shaft 13 extends into the circular shell 10. A plurality of moving blocks 19 are provided inside the circular shell 10. A plurality of moving blocks 19 all slide and extend outside the circular shell 10. A plurality of circumferentially distributed threaded sleeves 16 are rotatably installed on the inner wall of the circular shell 10. An arc plate 20 is fixedly connected to one side of each of the plurality of moving blocks 19; A shell 21 is provided at the bottom of the mounting plate 3. First damping pads 22 are fixedly connected to both sides of the inner wall of the shell 21. The same slide bar 23 is fixedly connected between the two first damping pads 22. Two symmetrically distributed first sliding blocks 24 are slidably installed on the outside of the slide bar 23; The rotating assembly is arranged inside the circular shell 10 and is used to drive a plurality of threaded sleeves 16 to rotate simultaneously; The moving assembly is arranged on the tops of two first sliding blocks 24 and is used to move the two first sliding blocks 24.

[0035] Among them, through the provided pipe clamp 2, the pipeline on the peristaltic pump body 1 can be fixed, avoiding the phenomenon of the pipeline coming loose from the peristaltic pump body 1. Place the peristaltic pump body 1 on the first support block 6 and the second support block 7. The first support block 6, the second support block 7 and the connecting block 8 are slidably installed inside the chute 4 through the self-locking slider 5, and thus the positions of the first support block 6, the second support block 7 and the connecting block 8 can be adjusted.

[0036] Move the circular shell 10 to the outside of the peristaltic pump body 1. By starting the motor 12, drive the rotating shaft 13 and the driving gear 14 to rotate. Since the driving gear 14 is meshed with the tooth disc 15, the tooth disc 15 can be driven to move in a circular motion. Since the tooth disc 15 is meshed with a plurality of driven gears 17, a plurality of driven gears 17 can be driven to rotate simultaneously, and then drive a plurality of threaded rods 18, moving blocks 19 and arc-shaped plates 20 to move. At this time, the arc-shaped plate 20 can clamp and fix the peristaltic pump body 1. Through the above-provided structure, the peristaltic pump body 1 can be installed on the mounting plate 3.

[0037] When the peristaltic pump body 1 vibrates during operation, the mounting plate 3 moves downward. Through the provided first rotating frame 25 and the first connecting rod 26, the two first sliding blocks 24 can be driven to move towards each other. The first sliding blocks 24 will squeeze the first spring 27, and the first spring 27 generates a squeezing force, which is transmitted to the first damping pad 22 for absorption. At this time, the peristaltic pump body 1 can be shock-absorbed. Through the provided second rotating frame 31 and the second connecting rod 32, the four second sliding blocks 30 can be driven to move simultaneously. The second sliding blocks 30 will squeeze the second spring 33 to generate a squeezing force, which is transmitted to the second damping pad 29 for absorption, and the peristaltic pump body 1 can be shock-absorbed for the second time. The shock-absorption effect is better. Through the above-provided structure, the vibration generated when the peristaltic pump body 1 works can be shock-absorbed, the noise is reduced, the service life is prolonged and the operation stability is improved. At the same time, the phenomenon of the pipeline coming loose due to vibration is avoided, which is convenient for the staff to use.

[0038] Moreover, the first spring 27 and the first damping pad 22, as well as the second spring 33 and the second damping pad 29 together constitute a frequency-selective frequency-dividing shock absorption effect. Specifically, the first-stage shock absorption is composed of the first spring 27 and the first damping pad 22. The first spring 27 is a low-stiffness spring, which can extend the transmission path of low-frequency vibrations and reduce the low-frequency vibrations during the startup of the motor 12. The second-stage shock absorption is constituted by the second spring 33 and the second damping pad 29. The second spring 33 is a high-stiffness spring, which is aimed at the high-frequency vibrations generated by non-linear impact vibration pulses to achieve full-frequency vibration suppression.

[0058] Move the circular shell 10 to the outside of the peristaltic pump main body 1.

Since the driving gear 14 is meshed with the toothed disc 15, the rotation of the driving gear 14 can drive the toothed disc 15 to perform a circular motion.

Subsequently, the four second sliding blocks 30 will squeeze the second spring 33, and the second spring 33 will generate a squeezing force, which will be transmitted to the second damping pad 29, and the second damping pad 29 will absorb the squeezing force. At this time, the peristaltic pump body 1 can be shock-absorbed for the second time, and the shock-absorbing effect is better.
