Description

Technical Field

[0001] The present invention belongs to the technical field of peristaltic pumps, and particularly relates to a peristaltic pump with a variable-direction liquid outlet. Background Art

[0002] A peristaltic pump is a precision fluid delivery device that relies on a roller assembly to circulate and roll outside an elastic hose, continuously squeezing and releasing the hose to cause the fluid inside the hose to move like intestinal peristalsis to achieve precise delivery. It can adapt to various hose materials and can transport a wide variety of fluid types, from conventional water, solutions to high-viscosity fluids, particulate media, etc. Moreover, since the fluid only contacts the inner wall of the hose, the delivery process is clean and pollution-free, and the flow rate can be adjusted simply and precisely, which can meet the diverse fluid delivery needs in many fields such as laboratory research, medical equipment, and industrial production.

[0003] When a common peristaltic pump is in use, generally the direction of the liquid outlet on the peristaltic pump is fixed, resulting in the inability to adjust the direction of the liquid outlet, making the applicable range of the peristaltic pump smaller and unable to be used in different scenarios. In addition, a general peristaltic pump only has the function of transporting liquids, which is relatively single. In view of this, we propose a peristaltic pump with a variable-direction liquid outlet. Summary of the Invention

[0004] The purpose of the present invention is to provide a peristaltic pump with a variable-direction liquid outlet to solve the problems raised in the above background art.

[0005] In view of this, the present invention provides a peristaltic pump with a variable-direction liquid outlet, including a peristaltic pump, and further including:

[0006] A water inlet pipe, which is fixedly installed at the water inlet of the peristaltic pump. A water outlet end is fixedly installed at the water outlet of the peristaltic pump. A connecting pipe is provided at the top of the water outlet end. A limiting groove is formed in the inner wall of the water outlet end. A first sealing ring is fixedly installed at the bottom of the limiting groove. A limiting block is fixedly installed at the bottom end of the connecting pipe and located within the limiting groove. A sealing pad in contact with the connecting pipe is fixedly installed at the top of the water outlet end;

[0007] A fastening assembly, which is located on the connecting pipe and is used to fasten the connecting pipe and the water outlet end;

[0008] A circular pipe, which is fixedly installed at one end of the connecting pipe. An annular groove is formed in the circular pipe. An annular plate is rotatably installed in the annular groove. A second sealing ring in contact with the annular groove is fixedly installed on the inner wall of the annular plate;

[0009] A limiting assembly, which is located within the circular pipe and is used to limit the annular plate;

[0010] A water outlet pipe, which is fixedly installed on the top of the annular plate. A slot is formed in the water outlet pipe, and a plug block is inserted and installed in the slot. A groove is formed in the top of the plug block, and a filter screen is inserted and installed in the groove.

[0011] A fixing component, which is located in the water outlet pipe and is used to fix the plug block.

[0012] In this technical solution, during use, when it is necessary to adjust the liquid outlet direction of the water outlet pipe, the operator can first release the limit on the annular plate through the limit component. The operator can rotate the annular plate, and the rotation of the annular plate will drive the water outlet pipe to rotate, thereby adjusting the vertical direction of the water outlet pipe. When adjusted to the appropriate angle, the limit component can limit the annular plate to ensure that it is convenient for the operator to adjust the vertical rotation angle of the water outlet pipe.

[0013] Subsequently, the operator can release the limit on the connecting pipe through the fastening component. The operator can rotate the connecting pipe, and the rotation of the connecting pipe will drive the circular pipe to rotate. The rotation of the circular pipe will drive the annular plate to rotate, and the rotation of the annular plate will drive the water outlet pipe to rotate. At this time, the horizontal angle of the water outlet pipe can be adjusted. When adjusted to the appropriate angle, the connecting pipe is tightened through the fastening component to ensure that it is convenient for the operator to adjust the horizontal rotation angle of the water outlet pipe.

[0014] When the water outlet pipe is discharging water, the filter screen can filter the water at this time, and filter out the impurities contained in the water, thereby ensuring the quality of the water. When the filter screen is used for a long time, the filter screen will become blocked, resulting in a deterioration of the filtering effect. At this time, the operator can release the limit on the plug block through the fixing component, and the operator can pull out the plug block from the slot through the handle. Subsequently, the operator can take out the filter screen from the groove and replace it, then insert the plug block back into the slot, and then limit the plug block through the fixing component to ensure that the water can be filtered when discharging water, and at the same time, it is convenient for the operator to replace the blocked filter screen and ensure that the filtering effect of the filter screen can be maintained in the best state.

[0015] In the above technical solution, further, the fastening component includes:

[0016] A limit ring, which is fixedly installed on the peripheral side of the connecting pipe and at the top of the water outlet end. A threaded nut is sleeved on the peripheral side of the connecting pipe. An inner wall of the threaded nut is fixedly installed with a rubber ring that contacts the limit ring. A plurality of anti-slip blocks are fixedly installed on the peripheral side of the threaded nut. A threaded groove is formed on the peripheral side of the water outlet end.

[0017] In this technical solution, when the threaded cap is rotated, under the action of the threaded groove, the threaded cap will move upward. At the same time, a number of anti-slip blocks can prevent people from slipping when rotating the threaded cap until the rubber ring in the threaded cap is far from the top of the limit ring. At this time, the threaded cap can release the limit on the connecting pipe, and people can rotate the connecting pipe. The rotation of the connecting pipe will drive the circular pipe to rotate, the rotation of the circular pipe will drive the annular plate to rotate, and the rotation of the annular plate will drive the water outlet pipe to rotate. At this time, the horizontal angle of the water outlet pipe can be adjusted. When the appropriate angle is adjusted, rotate the threaded cap again so that the threaded cap moves downward on the water outlet end until the rubber ring in the threaded cap is pressed against the top of the limit ring. At this time, the threaded cap can limit the connecting pipe to ensure that it is convenient for people to adjust the horizontal rotation angle of the water outlet pipe.

[0018] In the above technical solution, further, the threaded cap is in threaded connection with the threaded groove, and a number of the anti-slip blocks are distributed annularly and equidistantly.

[0019] In this technical solution, the structure of the threaded cap and the threaded groove is ensured to be stable, and a number of anti-slip blocks are guaranteed to be more evenly distributed.

[0020] In the above technical solution, further, the limiting component includes:

[0021] Two limiting plates, the two limiting plates are respectively fixedly installed on both sides of the annular plate and located in the annular groove. A number of limiting holes are provided on one of the limiting plates. A threaded rod is threadedly installed on the circular pipe, and one end of the threaded rod extends into one of the limiting holes, and the other end of the threaded rod is fixedly installed with a knob.

[0022] In this technical solution, when the knob is rotated, the rotation of the knob will drive the threaded rod to rotate. Under the action of the thread, the rotation of the threaded rod will move in the circular pipe until one end of the threaded rod moves out of one of the limiting holes. At this time, the limit on one of the limiting plates can be released, and thus the limit on the annular plate can be released. People can rotate the annular plate, and the rotation of the annular plate will drive the water outlet pipe to rotate, thereby adjusting the vertical direction of the water outlet pipe. When the appropriate angle is adjusted, rotate the knob again so that one end of the threaded rod is inserted into the corresponding limiting hole. At this time, the annular plate can be limited to ensure that it is convenient for people to adjust the vertical rotation angle of the water outlet pipe.

[0023] In the above technical solution, further, one end of the threaded rod is in plug-in fit with the limiting hole, a number of the limiting holes are distributed in a fan shape, and the limiting plate is rotatably connected with the annular groove.

[0024] In this technical solution, it is ensured that one end of the threaded rod can be inserted into the limiting hole, the structure of a number of limiting holes is guaranteed to be stable, and it is guaranteed that the limiting plate can rotate normally in the annular groove.

[0025] In the above technical solution, further, the fixing component includes:

[0026] A sliding groove is provided in the water outlet pipe and above the insertion block. A spring block is slidably installed in the sliding groove. The bottom end of the spring block penetrates through the bottom of the sliding groove and extends into the insertion block. A spring fixed to the top of the sliding groove is fixedly installed at the top end of the spring block. One side of the spring block penetrates through the sliding groove and extends to the outside and is fixedly installed with a moving plate.

[0027] In this technical solution, a person can move the moving plate upward. When the moving plate moves upward, it will drive the spring block to move upward. When the spring block moves upward, it will compress the spring to contract. Until the bottom end of the spring block moves out of the insertion block, at this time, the limit on the insertion block can be released. Then the person can take out the filter screen from the groove and replace it, and then insert the insertion block back into the slot. At this time, under the action of the spring's rebounding force, the spring will push the spring block downward until the bottom end of the spring block inserts into the insertion block. At this time, the insertion block can be limited, ensuring that the water can be filtered when the water comes out, and at the same time, it is also convenient for the person to replace the blocked filter screen, ensuring that the filtering effect of the filter screen can be maintained in the best state.

[0028] In the above technical solution, further, the bottom end of the spring block is in plug-in fit with the insertion block.

[0029] In this technical solution, it is ensured that the bottom end of the spring block can insert into the insertion block.

[0030] In the above technical solution, further, a handle is fixedly installed on one side of the insertion block, and a plurality of anti-detachment blocks are fixedly installed on the circumference of the water outlet pipe and above the slot.

[0031] In this technical solution, it is ensured that a person can pull out the insertion block from the slot through the handle, ensuring that when a water pipe is sleeved on the water outlet pipe, it will not fall off.

[0032] In the above technical solution, further, the limiting block is rotatably connected to the limiting groove. The bottom end of the limiting block is in close contact with the first sealing ring. The top of the filter screen is in contact with the top of the slot.

[0033] In this technical solution, it is ensured that the limiting block can rotate normally in the limiting groove, ensuring the sealing performance of the first sealing ring and ensuring that the filter screen will not shake.

[0034] In the above technical solution, further, the water outlet end is communicated with the connecting pipe, the round pipe and the water outlet pipe.

[0035] In this technical solution, it is ensured that the structure of the water outlet end, the connecting pipe, the round pipe and the water outlet pipe is stable.

[0036] The beneficial effects of the present invention are:

[0037] 1. The peristaltic pump with a variable-direction liquid outlet, through the set limit component, under the mutual cooperation of the limit component, annular plate, fastening component, connecting pipe, round pipe and water outlet pipe, ensures that it is convenient for personnel to adjust the vertical rotation angle of the water outlet pipe, and it is also convenient for personnel to adjust the horizontal rotation angle of the water outlet pipe, ensuring that it is convenient for personnel to adjust the water outlet pipe at multiple angles arbitrarily.

[0062] The limiting component is located inside the circular pipe 12 and is used to limit the annular plate 14;

[0063] The water outlet pipe 20 is fixedly installed on the top of the annular plate 14. A slot 22 is formed in the water outlet pipe 20. A plug-in block 23 is inserted and installed in the slot 22. A groove 29 is formed in the top of the plug-in block 23. A filter net 24 is inserted and installed in the groove 29;

[0064] The fixing component is located inside the water outlet pipe 20 and is used to fix the plug-in block 23.

[0065] Among them, when in use, when it is necessary to adjust the liquid outlet direction of the water outlet pipe 20, the operator can first release the limit on the annular plate 14 through the limiting component. The operator can rotate the annular plate 14. The rotation of the annular plate 14 will drive the water outlet pipe 20 to rotate, thereby adjusting the vertical direction of the water outlet pipe 20. When adjusted to the appropriate angle, the limiting component can limit the annular plate 14 to ensure that it is convenient for the operator to adjust the vertical rotation angle of the water outlet pipe 20;

[0066] Subsequently, the operator can release the limit on the connecting pipe 4 through the fastening component. The operator can rotate the connecting pipe 4. The rotation of the connecting pipe 4 will drive the circular pipe 12 to rotate. The rotation of the circular pipe 12 will drive the annular plate 14 to rotate.

A number of anti-slip blocks 10 are fixedly installed on the periphery of the threaded cap 9. A threaded groove 31 is formed on the periphery of the water outlet end 3.

[0070] Among them, by rotating the threaded cap 9, under the action of the threaded groove 31, the threaded cap 9 will move upward. At the same time, a number of anti-slip blocks 10 can prevent people from slipping when rotating the threaded cap 9 until the rubber ring 11 in the threaded cap 9 is far from the top of the limiting ring 8. At this time, the threaded cap 9 can release the limit on the connecting pipe 4, and people can rotate the connecting pipe 4. The rotation of the connecting pipe 4 will drive the circular pipe 12 to rotate. The rotation of the circular pipe 12 will drive the annular plate 14 to rotate. The rotation of the annular plate 14 will drive the water outlet pipe 20 to rotate. At this time, the horizontal angle of the water outlet pipe 20 can be adjusted. When adjusted to the appropriate angle, rotate the threaded cap 9 again so that the threaded cap 9 moves downward on the water outlet end 3 until the rubber ring 11 in the threaded cap 9 is pressed against the top of the limiting ring 8. At this time, the threaded cap 9 can limit the connecting pipe 4 to ensure that it is convenient for people to adjust the horizontal rotation angle of the water outlet pipe 20.

[0073] Embodiment 4: This embodiment provides a peristaltic pump with a variable-direction liquid outlet. In addition to the technical solutions of the above embodiment, it also has the following technical features. The limiting assembly includes:

[0074] Two limiting plates 16, which are respectively fixedly installed on both sides of the annular plate 14 and located in the annular groove 13.

One end of the threaded rod 18 extends into one of the limiting holes 17, and the other end of the threaded rod 18 is fixedly installed with a knob 19.

[0075] Among them, by rotating the knob 19, the rotation of the knob 19 will drive the threaded rod 18 to rotate. Under the action of the thread, the rotation of the threaded rod 18 will cause it to move within the circular tube 12. When one end of the threaded rod 18 moves out of one of the limiting holes 17, at this time, the limit on one of the limiting plates 16 can be released, thereby releasing the limit on the annular plate 14. The operator can rotate the annular plate 14, and the rotation of the annular plate 14 will drive the water outlet pipe 20 to rotate, thereby adjusting the vertical direction of the water outlet pipe 20. When adjusted to the appropriate angle, rotate the knob 19 again so that one end of the threaded rod 18 is inserted into the corresponding limiting hole 17.

One side of the spring block 26 penetrates the sliding groove 25 and extends to the outside and is fixedly installed with a moving plate 28.

[0080] Among them, the operator can move the moving plate 28 upward. The upward movement of the moving plate 28 will drive the spring block 26 to move upward. The upward movement of the spring block 26 will compress the spring 27 to contract. When the bottom end of the spring block 26 moves out of the plug-in block 23, at this time, the limit on the plug-in block 23 can be released. Subsequently, the operator can take out the filter screen 24 from the groove 29 and replace it, and then insert the plug-in block 23 back into the slot 22. At this time, under the action of the rebounding force of the spring 27, the spring 27 will squeeze the spring block 26 to move downward until the bottom end of the spring block 26 is inserted into the plug-in block 23. At this time, the plug-in block 23 can be limited, ensuring that the water can be filtered when discharging water, and at the same time, it is convenient for the operator to replace the blocked filter screen 24, ensuring that the filtering effect of the filter screen 24 can be maintained in the best state.

In addition to the technical solutions of the above embodiments, it also has the following technical features. The water outlet end 3 is communicated with the connecting pipe 4, the round pipe 12 and the water outlet pipe 20.

[0088] Among them, it is ensured that the structures of the water outlet end 3, the connecting pipe 4, the round pipe 12 and the water outlet pipe 20 are stable.

[0089] Working principle: When in use, when it is necessary to adjust the liquid outlet direction of the water outlet pipe 20, the operator can first rotate the knob 19. The rotation of the knob 19 will drive the threaded rod 18 to rotate. Under the action of the thread, the rotation of the threaded rod 18 will cause it to move within the circular tube 12. When one end of the threaded rod 18 moves out of one of the limit holes 17, at this time, the limit on one of the limit plates 16 can be released, thereby releasing the limit on the annular plate 14. The operator can rotate the annular plate 14, and the rotation of the annular plate 14 will drive the water outlet pipe 20 to rotate, thereby adjusting the vertical direction of the water outlet pipe 20. When the appropriate angle is adjusted, rotate the knob 19 again so that one end of the threaded rod 18 is inserted into the corresponding limit hole 17. At this time, the annular plate 14 can be limited, ensuring that it is convenient for the operator to adjust the vertical rotation angle of the water outlet pipe 20;

[0090] Subsequently, the operator can rotate the threaded cap 9. Under the action of the thread groove 31, the threaded cap 9 will move upward. At the same time, a number of anti-slip blocks 10 can prevent the operator from slipping when rotating the threaded cap 9 until the rubber ring 11 in the threaded cap 9 is far from the top of the limit ring 8. At this time, the threaded cap 9 can release the limit on the connecting pipe 4. The operator can rotate the connecting pipe 4, and the rotation of the connecting pipe 4 will drive the circular tube 12 to rotate. The rotation of the circular tube 12 will drive the annular plate 14 to rotate, and the rotation of the annular plate 14 will drive the water outlet pipe 20 to rotate. At this time, the horizontal angle of the water outlet pipe 20 can be adjusted. When the appropriate angle is adjusted, rotate the threaded cap again so that the threaded cap 9 moves downward on the water outlet end 3 until the rubber ring 11 in the threaded cap 9 presses against the top of the limit ring 8. At this time, the threaded cap 9 can limit the connecting pipe 4, ensuring that it is convenient for the operator to adjust the horizontal rotation angle of the water outlet pipe 20;

[0091] When the water outlet pipe 20 is discharging water, at this time, the filter screen 24 can filter the water and filter out the impurities contained in the water, thereby ensuring the quality of the water. When the filter screen 24 is used for a long time, the filter screen 24 will become clogged, resulting in a deterioration of the filtering effect. At this time, the operator can move the moving plate 28 upward. The upward movement of the moving plate 28 will drive the elastic block 26 to move upward. The upward movement of the elastic block 26 will squeeze the spring 27 to contract until the bottom end of the elastic block 26 moves out of the plug-in block 23. At this time, the limit on the plug-in block 23 can be released. The operator can pull out the plug-in block 23 from the slot 22 through the handle 30. Subsequently, the operator can take out the filter screen 24 from the groove 29 and replace it. Then insert the plug-in block 23 back into the slot 22. At this time, under the action of the elastic force of the spring 27, the spring 27 will squeeze the elastic block 26 to move downward until the bottom end of the elastic block 26 is inserted into the plug-in block 23. At this time, the plug-in block 23 can be limited, ensuring that the water can be filtered when discharging water, and at the same time, it is convenient for the operator to replace the clogged filter screen 24 and ensure that the filtering effect of the filter screen 24 can be maintained in the best state.
