Description

Technical Field

[0001] This invention relates to the field of pump base technology, and more specifically, to a pump base with shock absorption and noise reduction functions. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. A pump typically consists of a base, pump body, pump head, and electric motor.

[0003] During operation, the pump vibrates due to the operation of the motor, transmission mechanism, and crankshaft. This not only generates significant noise but also affects the pump's lifespan. Furthermore, since the pump base is bolted to the pump body and pump head, maintenance requires disassembling the pump base, which is labor-intensive and repeated bolt disassembly and reassembly can affect the stability of the connection between the pump base and the pump body. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a pump base with shock absorption and noise reduction functions. Utilizing rubber balls and rubber pads, friction and collision forces between the fixed base and connecting components are reduced. When the movable base plate moves upward inside the base housing, the rubber air bladder resets the movable base plate via a reset sponge and buffer spring, thereby achieving shock absorption and noise reduction, extending the pump's service life. A one-way valve blows gas onto the pump body and accelerates airflow around the pump body, cooling the pump body while it vibrates during operation, increasing its heat dissipation efficiency. Furthermore, rotating the pump body causes the rotating block to rotate, allowing the mounting plate to rotate on the surface of the pump body mounting bracket, thus exposing the connection between the pump body and the pump head for easy maintenance and repair without disassembly, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pump base with shock absorption and noise reduction function, comprising a fixed base, a connecting component movably installed inside the fixed base, a movable base provided at one end of the top of the connecting component, and a limiting base provided at the other end of the top of the connecting component.

[0008] In a preferred embodiment, a first damping block is fixedly connected to each of the four corners of the bottom surface inside the base housing, and a limit rod is fixedly connected inside the first damping block at each of the four corners of the base housing. A buffer spring is sleeved on the outer surface of the limit rod at the top of the first damping block.

[0009] In a preferred embodiment, the connecting assembly includes a movable base plate, a movable plate fixedly connected to the top of the movable base plate, a mounting plate fixedly connected to the top of the movable plate, the movable base plate being movably mounted inside the base housing, and second damping blocks fixedly connected to the four corners of the bottom of the movable base plate. The movable base plate and the second damping blocks are movably sleeved on the outer surface of the limiting rod, the second damping blocks being located on top of the buffer spring. Inserting feet are fixedly connected to both ends of the bottom surface of the mounting plate, and the inserting feet are inserted into the inserting holes on the top of the rubber ball. The movable plate is movably mounted on the top of the base housing.

[0010] In a preferred embodiment, rubber pads are fixedly connected to the top of both ends of the movable base plate. The rubber pads are located between the movable base plate and the base shell. A second magnet is embedded in the interior of the movable base plate. The interior of the second magnet has a sleeve groove. The sleeve groove is fixedly sleeved on the outer surface of the air outlet. The magnetic poles at the bottom of the second magnet are the same as the magnetic poles on the surface of the first magnet.

[0011] In a preferred embodiment, the mounting plate includes a pump head mounting base and a pump body mounting bracket. The surface of the pump head mounting base is fixedly connected to the pump head by bolts, and the pump head mounting base is fixedly mounted on one end of the movable plate.

[0012] In a preferred embodiment, the pump body mounting bracket is fixedly installed at the other end of the movable plate, and a fixing rod is fixedly connected to one end of the pump body mounting bracket. A sliding frame is fixedly connected to one side of the fixing rod and the side of the pump head mounting seat. A sliding groove is provided inside the sliding frame, and an interlocking sliding groove is provided inside the pump body mounting bracket away from the pump head mounting seat.

[0013] In a preferred embodiment, the movable base includes a sliding seat, a rotating block is rotatably mounted on the top of the sliding seat, a connecting rod is fixedly connected to the top of the rotating block, and mounting plates are fixedly connected to both ends of the connecting rod. The sliding seat is slidably mounted inside the sliding groove, the connecting rod is movably mounted on the top of the sliding frame, and the mounting plate is slidably mounted on the surface of the pump body mounting frame. The surface of the mounting plate is fixedly connected to one end of the pump body by bolts.

[0014] In a preferred embodiment, the limiting base includes a mounting base plate, the bottom of which is fixedly connected to an interlocking block, the interlocking block being slidably mounted inside an interlocking groove, the mounting base plate being slidably mounted on the surface of the pump body mounting bracket, and the top of the mounting base plate being fixedly connected to the other end of the pump body by bolts.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. This invention utilizes a rubber airbag to generate deformation. Because the second and first magnets have the same magnetic poles, like poles repel each other. When the movable base plate is subjected to vibration, it experiences a repulsive force, reducing the vibration amplitude of the connecting components. Simultaneously, the compressed buffer spring acts on the surfaces of the first and second damping blocks, providing shock absorption. Rubber balls and pads further reduce friction and impact forces between the fixed base and the connecting components. When the movable base plate moves upward inside the base shell, the rubber airbag resets the movable base plate via a reset sponge and buffer spring. At this time, air enters through the air inlet via a one-way valve, causing the rubber airbag to expand. The one-way valve prevents gas inside the rubber airbag from escaping through the air inlet, thus achieving vibration reduction and noise reduction, and extending the pump's service life.

[0017] 2. By setting the movable plate in a hollow state, when the rubber airbag is squeezed, the air inside the rubber airbag is discharged from the one-way valve of the air outlet. The one-way valve blows the gas to the pump body and accelerates the air flow around the pump body, so that the pump body is cooled down while it is vibrating during operation, thereby increasing the heat dissipation efficiency of the pump body.

[0018] 3. By setting up a movable base and a limiting base, when the pump needs to be repaired, it is only necessary to disassemble the pump body and pump head, rotate the bolt to disengage the bolt from the inside of the pump body mounting bracket, and pull the pump body to the right to move the interlocking block out of the interlocking groove. The mounting slide slides on the surface of the pump body mounting bracket. By rotating the pump body, the rotating block rotates, causing the mounting slide to rotate on the surface of the pump body mounting bracket, thereby exposing the connection between the pump body and the pump head, which is convenient for repair and maintenance without disassembly.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] As attached Figure 1-4 The pump base shown includes a fixed base 1, a connecting component 2 movably installed inside the fixed base 1, a movable base 3 at one end of the top of the connecting component 2, and a limiting base 4 at the other end of the top of the connecting component 2. The fixed base 1 includes a base shell 11, mounting ears 12 fixedly connected to both sides of the base shell 11, ventilation holes 13 at both ends of the base shell 11, rubber balls 14 fixedly connected to the four corners of the top of the base shell 11, fitting holes 15 on the top of the rubber balls 14, a buffer airbag 16 fitted inside the base shell 11, sound-absorbing cotton 18 fixedly connected to the bottom surface inside the base shell 11, and a first magnet 17 fitted in the middle of the bottom surface inside the base shell 11. The rubber balls 14 limit the movement of the connecting component 2. When the connecting component 2 is subjected to vibration, the rubber balls 14 prevent friction between the connecting component 2 and the fixed base 1 from generating noise, while supporting the connecting component 2 and reducing the shaking of the connecting component 2.

[0030] The cushioning airbag 16 includes a rubber airbag body 161. An air outlet 162 is fixedly connected to one end of the top of the rubber airbag body 161. An air outlet valve 163 is installed inside the air outlet 162. Air inlets 164 are provided on both sides of the rubber airbag body 161. An air inlet valve 165 is installed inside the air inlet 164. A reset sponge 167 is placed inside the rubber airbag body 161. The rubber airbag body 161 is embedded inside the base housing 11, and the air inlets 164 are embedded in the ventilation holes 13. Inside, a reset sponge 167 is installed to support the rubber airbag 161 while increasing its resilience without affecting its air intake and exhaust performance. Meanwhile, an intake check valve 165 and an exhaust check valve 163 are respectively installed on both sides and one end of the top of the rubber airbag 161, allowing the rubber airbag 161 to take in air through the intake nozzle 164 and exhaust air through the exhaust check valve 163, thereby cooling the pump body and improving its heat dissipation effect.

[0031] The base housing 11 has four corners of the bottom surface inside the base housing 11 fixedly connected to a first damping block 19. The four corners of the base housing 11 are fixedly connected to the inside of the first damping block 19. The outer surface of the limit rod 110 is fitted with a buffer spring 111 on the top of the first damping block 19. The second damping block 25 and the first damping block 19 are made of polymer or rubber materials, have stable physical and chemical properties, and have excellent vibration reduction and noise reduction, heat resistance, cold resistance, anti-aging and strong adhesion.

[0032] As attached Figure 5 As shown, the connecting assembly 2 includes a movable base plate 21, a movable plate 22 fixedly connected to the top of the movable base plate 21, and a mounting plate 23 fixedly connected to the top of the movable plate 22. The movable base plate 21 is movably installed inside the base housing 11. Second damping blocks 25 are fixedly connected to the four corners of the bottom of the movable base plate 21. The movable base plate 21 and the second damping blocks 25 are movably sleeved on the outer surface of the limiting rod 110. The second damping blocks 25 are located on the top of the buffer spring 111. Both ends of the bottom surface of the mounting plate 23 are fixedly connected to the inserting feet 24. The inserting feet 24 are inserted into the inserting holes 15 on the top of the rubber ball 14. The movable plate 22 is movably installed on the top of the base housing 11.

[0033] Rubber pads 27 are fixedly connected to the top of both ends of the movable base plate 21. The rubber pads 27 are located between the movable base plate 21 and the base shell 11. A second magnet 26 is embedded inside the movable base plate 21. The second magnet 26 has a sleeve groove 28 inside. The sleeve groove 28 is fixedly sleeved on the outer surface of the air outlet 162. The magnetic pole at the bottom of the second magnet 26 is the same as the magnetic pole on the surface of the first magnet 17. Since the magnetic poles of the second magnet 26 and the first magnet 17 are the same, the like poles repel each other, so that the movable base plate 21 is located at the top inside the base shell 11. At the same time, when the movable base plate 21 is subjected to vibration, it will be subjected to repulsive force, which reduces the vibration amplitude of the connecting component 2.

[0034] As attached Figure 6 As shown, the mounting plate 23 includes a pump head mounting base 231 and a pump body mounting bracket 232. The surface of the pump head mounting base 231 is fixedly connected to the pump head by bolts, and the pump head mounting base 231 is fixedly mounted on one end of the movable plate 22.

[0035] The pump body mounting bracket 232 is fixedly installed on the other end of the movable plate 22. A fixing rod 233 is fixedly connected to one end of the pump body mounting bracket 232. A sliding bracket 234 is fixedly connected to one side of the fixing rod 233 and the side of the pump head mounting seat 231. A sliding groove 235 is opened inside the sliding bracket 234. An interlocking sliding groove 236 is opened inside the pump body mounting bracket 232 away from the pump head mounting seat 231.

[0036] As attached Figure 7 As shown, the movable base 3 includes a sliding seat 31, a rotating block 32 is rotatably mounted on the top of the sliding seat 31, a connecting rod 33 is fixedly connected to the top of the rotating block 32, and mounting slide plates 34 are fixedly connected to both ends of the connecting rod 33. The sliding seat 31 is slidably mounted inside the sliding groove 235, the connecting rod 33 is movably mounted on the top of the sliding frame 234, and the mounting slide plate 34 is slidably mounted on the surface of the pump body mounting frame 232. The surface of the mounting slide plate 34 is fixedly connected to one end of the pump body by bolts.

[0037] As attached Figure 8 As shown, the limiting base 4 includes a mounting base plate 41, and a locking block 42 is fixedly connected to the bottom of the mounting base plate 41. The locking block 42 is slidably installed inside the locking groove 236. The mounting base plate 41 is slidably installed on the surface of the pump body mounting bracket 232. The top of the mounting base plate 41 is fixedly connected to the other end of the pump body by bolts.

[0038] Working principle of the invention: During installation, the pump head is bolted to the top of the pump head mounting base 231, and the pump body is bolted to the surface of the mounting slide plate 34 and the mounting base plate 41. When the pump vibrates during operation, the movable base plate 21 vibrates inside the base housing 11 and presses against the surface of the rubber air bladder 161. At this time, the rubber air bladder 161 deforms, and the gas inside the rubber air bladder 161 is discharged through the one-way valve 163 in the air outlet 162. Because the magnetic poles of the second magnet 26 and the first magnet 17 are the same, the like poles repel each other, causing the movable base plate 21 to be positioned at the top of the base housing 11. Simultaneously, when the movable base plate 21 is subjected to vibration, it experiences a repulsive force, reducing the contact force of the connecting assembly 2. The vibration amplitude is reduced. At the same time, the buffer spring 111 is compressed and acts on the surface of the first damping block 19 and the second damping block 25. The second damping block 25 acts to dampen the vibration. The rubber ball 14 and the rubber pad 27 are used to reduce the friction and collision force between the fixed base 1 and the connecting component 2. When the movable base plate 21 moves upward inside the base shell 11, the rubber airbag 161 resets the movable base plate 21 through the reset sponge 167 and the buffer spring 111. At this time, the air inlet 164 takes in air through the air inlet one-way valve 165, causing the rubber airbag 161 to expand. Through the action of the air inlet one-way valve 165, the gas inside the rubber airbag 161 is prevented from being discharged through the air inlet 164, thereby achieving the effect of vibration reduction and noise reduction.

[0039] In addition, since the movable plate 22 is in a hollow state, when the rubber air bladder 161 is squeezed, the air inside the rubber air bladder 161 is discharged from the one-way valve 163 of the air outlet 162. The one-way valve 163 blows the gas to the pump body and accelerates the air flow around the pump body. So that while the pump is vibrating during operation, the gas inside the rubber air bladder 161 in the base shell 11 keeps blowing the pump body, thereby cooling the pump body.

[0040] In addition, due to the installation of the movable base 3 and the limiting base 4, when the pump needs to be maintained, it is only necessary to disassemble the pump body and the pump head, rotate the bolt to disengage the bolt from the inside of the pump body mounting bracket 232, and pull the pump body to the right to move the interlocking block 42 out of the inside of the interlocking groove 236. The mounting slide 34 slides on the surface of the pump body mounting bracket 232. By rotating the pump body, the rotating block 32 rotates, causing the mounting slide 34 to rotate on the surface of the pump body mounting bracket 232, thereby exposing the connection between the pump body and the pump head.

[0041] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
