Description

Technical Field

[0001] This utility model relates to the field of oxygenation pumps, specifically a silent suspension structure for an air pump. Background Technology

[0002] An air pump is a device that increases the dissolved oxygen content of water by mechanically or electromagnetically pressurizing air into it. It is widely used in aquaculture, wastewater treatment, and industrial fields. Its working principle mainly relies on the centrifugal force generated by the rotation of the impeller, which causes the air to move in a spiral shape and be compressed before being discharged. The diffuser forms small bubbles to improve the oxygen dissolution efficiency. Air pumps have the characteristics of blowing and suction functions, low noise, and maintenance-free operation. They come in various types, including small household pumps, industrial high-pressure pumps, and intelligent adjustable products. The appropriate power should be selected according to the depth of the aquarium and the stocking density.

[0003] Currently, air pumps used in bathtubs can quickly oxygenate the water inside the bathtub, providing water with a high oxygen concentration. However, there is a problem in actual use: the compatibility between traditional air pumps and bathtubs is the main issue. Therefore, the inventors urgently need to design an air pump and aquarium installation structure with high compatibility to improve the ease of use of the air pump. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a silent suspension structure for an air pump to solve the technical problem of poor compatibility between traditional air pumps and fish tanks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silent suspension structure for an air pump, comprising an air pump body, a storage groove on the back of the air pump body, two sets of clamping mechanisms mirror-mounted inside the storage groove, each clamping mechanism comprising a rotating block, the rotating block being rotatably mounted to the inner wall of the storage groove, a clamping rod being rotatably mounted on one side of the rotating block, a sliding rod being slidably mounted on the inner side of the clamping rod, and the rotating block and the clamping rod forming an "L" shape.

[0006] By adopting the above technical solution, the clamping mechanism is concealed through the storage groove on the back of the air pump body, which significantly optimizes the overall compactness of the equipment. The two sets of mirror-symmetrical clamping mechanisms work together to form a clamping force arm by the L-shaped structure formed by the rotating block and the clamping rod.

[0007] Furthermore, the rotating block has a slot inside, and a telescopic rod is slidably installed inside the slot. The outer end of the telescopic rod is fixedly connected to the clamping rod.

[0008] By adopting the above technical solution, the internal slot of the rotating block and the sliding cooperation of the telescopic rod form an elastic telescopic channel, which makes the clamping force transmission path have buffer characteristics. The rigid connection between the outer end of the telescopic rod and the clamping rod ensures that the pressure is evenly distributed to the clamping surface and prevents local stress concentration.

[0009] Furthermore, a tension spring is elastically connected between the inner wall of the telescopic rod and the slot to provide the clamping force of the clamping rod on the cylinder wall.

[0010] By adopting the above technical solution, the pre-tightening connection between the tension spring and the slot on the inner wall of the telescopic rod provides a continuous and stable elastic clamping force for the clamping mechanism. This elastic system enables the clamping rod to automatically compensate for the dimensional tolerance or slight deformation of the cylinder wall and always maintain a constant clamping force.

[0011] Furthermore, the slide bar has a "T" shaped cross-section and engages with and slides inside the clamping rod.

[0012] By adopting the above technical solution, the T-shaped cross-section of the slide bar forms an anti-disengagement structure on the inside of the clamping rod, ensuring smooth sliding while completely eliminating the risk of structural loosening under vibration.

[0013] Furthermore, a first washer is attached to one side of the slide bar and clamping bar.

[0014] By adopting the above technical solution, the first gasket covers the contact surface of the slide rod and the clamping rod, and the high damping characteristics of the rubber material consume the vibration energy of the clamping mechanism, thus blocking the solid sound transmission path.

[0015] Furthermore, a second gasket is attached to the back of the air pump body, and both the first and second gaskets are made of rubber.

[0016] By adopting the above technical solution, the rubber material has both high resilience and wear resistance, which not only avoids scratching the glass surface, but also ensures that it maintains its sealing and cushioning performance after long-term compression.

[0017] Furthermore, a control button is provided on the front surface of the air pump body, and an air pump connection port is provided on one side of the top of the air pump body.

[0018] By adopting the above technical solution, the control buttons are located on the front surface of the air pump body, which conforms to the ergonomic operation path, allowing users to quickly start and stop the equipment without changing its orientation.

[0019] In summary, the present invention has the following main advantages:

[0020] This utility model integrates two sets of mirror-symmetrical clamping mechanisms through the storage groove on the back of the air pump body via the suspension structure, so that the rotating block and the clamping rod form an L-shaped clamping arm, solving the problem of poor adaptability of traditional installation. At the same time, the sliding design of the slide rod inside the clamping rod, combined with the elastic extension and retraction of the telescopic rod in the slot of the rotating block, realizes the adaptive adjustment of the clamping distance, which can be adapted to cylinder walls of different thicknesses. First, the tension spring connects the telescopic rod and the slot, providing continuous elastic force to ensure clamping stability.

[0021] This invention uses a first pad covered by a clamping mechanism and a second pad on the back of the air pump body to form a double rubber buffer layer, which blocks the vibration transmission path. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In this embodiment: a silent suspension structure for an air pump, such as... Figure 1-5As shown, the device includes an air pump body 1. A storage slot 4 is provided on the back of the air pump body 1. Two clamping mechanisms 5 are mirror-mounted inside the storage slot 4. Each clamping mechanism 5 includes a rotating block 501, which is rotatably mounted to the inner wall of the storage slot 4. A clamping rod 502 is rotatably mounted on one side of the rotating block 501, and a sliding rod 506 is slidably mounted on the inner side of the clamping rod 502. The rotating block 501 and the clamping rod 502 form an "L" shape. The storage slot 4 on the back of the air pump body 1 achieves a concealed layout of the clamping mechanisms 5, significantly improving performance. The overall compactness of the equipment is optimized. The two sets of mirror-symmetrical clamping mechanisms 5 work together to form a clamping force arm in the L-shaped structure composed of the rotating block 501 and the clamping rod 502. At the same time, the sliding installation mechanism of the slide rod 506 inside the clamping rod 502 allows the clamping width to be adaptively adjusted, which can not only adapt to cylinder walls of different thicknesses, but also avoid glass damage caused by rigid collisions. This structure also achieves multi-angle installation adaptability through the rotating connection between the rotating block 501 and the storage groove 4, completely solving the technical defects of the traditional air pump's limited installation position.

[0030] See Figure 4 , Figure 5 The rotating block 501 has a slot 503 inside, and a telescopic rod 504 is slidably installed inside the slot 503. The outer end of the telescopic rod 504 is fixedly connected to the clamping rod 502. The sliding cooperation between the slot 503 inside the rotating block 501 and the telescopic rod 504 forms an elastic telescopic channel, which makes the clamping force transmission path have buffer characteristics. The rigid connection between the outer end of the telescopic rod 504 and the clamping rod 502 ensures that the pressure is evenly distributed to the clamping surface and prevents local stress concentration. At the same time, it realizes dual-degree-of-freedom movement: the clamping rod 502 can rotate around the rotating block 501 to adjust the installation angle, while the linear sliding of the telescopic rod 504 in the slot 503 precisely controls the clamping distance. This composite movement mechanism enables the equipment to adapt to complex contours such as curved cylinder walls and glass seams, significantly improving the versatility of installation scenarios.

[0031] See Figure 4 , Figure 5 A tension spring 505 is elastically connected between the inner wall of the telescopic rod 504 and the slot 503 to provide the clamping force of the clamping rod 502 on the cylinder wall. The pre-tight connection between the tension spring 505 and the inner wall of the telescopic rod 504 and the slot 503 provides a continuous and stable elastic clamping force for the clamping mechanism 5. This elastic system enables the clamping rod 502 to automatically compensate for the dimensional tolerance or slight deformation of the cylinder wall and always maintain a constant clamping force. At the same time, the radial tension design of the spring avoids the metal fatigue caused by repeated torsion of traditional torsion springs, which greatly extends the service life of the mechanism. More importantly, the elastic deformation of the tension spring 505 can absorb the longitudinal vibration energy generated by the operation of the air pump body 1, blocking the transmission path of mechanical vibration to the cylinder wall from the source and achieving passive vibration reduction.

[0032] See Figure 4 The slide rod 506 has a "T" shaped cross-section. The slide rod 506 engages and slides inside the clamping rod 502. The T-shaped cross-section of the slide rod 506 forms an anti-detachment structure inside the clamping rod 502, ensuring smooth sliding while completely eliminating the risk of structural loosening under vibration. At the same time, the telescopic side of the slide rod 506 forms a surface contact with the tank wall, resulting in a more uniform pressure distribution and effectively preventing stress cracks in thin-walled aquariums.

[0033] See Figure 3 , Figure 4 , Figure 5 A first gasket 601 is attached to one side of the slide rod 506 and the clamping rod 502. The first gasket 601 covers the contact surface of the slide rod 506 and the clamping rod 502. The high damping characteristics of the rubber material consume the vibration energy of the clamping mechanism and block the solid sound transmission path. The second gasket 602 is attached to the back of the air pump body 1 and directly contacts the cylinder wall to form a secondary vibration isolation layer.

[0034] See Figure 3 , Figure 4 , Figure 5 The back of the air pump body 1 is attached with a second gasket 602. Both the first gasket 601 and the second gasket 602 are made of rubber. The rubber material has both high resilience and wear resistance, which not only avoids scratching the glass surface, but also ensures that the sealing and buffering performance is maintained after long-term compression. The soft contact characteristics of the gasket also compensate for the manufacturing tolerance of the clamping mechanism 5 and improve assembly compatibility.

[0035] See Figure 1 The front surface of the air pump body 1 is equipped with a control button 2, and the top side of the air pump body 1 is equipped with an air pump connection port 3. The control button 2 is located on the front surface of the air pump body 1, which conforms to the ergonomic operation path. Users can start and stop the equipment quickly without changing its orientation. At the same time, the air outlet is positioned at the top to ensure that the air pipe hangs down naturally, which not only avoids the impact of installation stress on the life of components, but also provides an independent operating area for maintenance and repair.

[0036] The implementation principle of this embodiment is as follows: First, press the air pump body 1 so that the storage groove 4 on its back is aligned with the edge of the aquarium wall. At this time, the two sets of mirror-arranged clamping mechanisms 5 contact the aquarium wall and generate a linkage reaction - the rotating block 501 rotates in the storage groove 4, driving the clamping rod 502 to rotate synchronously to form an L-shaped clamping angle. During the clamping process, the slide rod 506 slides and extends along the inner side of the clamping rod 502. At the same time, the telescopic rod 504 slides in the slot 503 of the rotating block 501. Through the elastic action of the tension spring 505, the clamping rod 502 generates an adaptive clamping force. The two sides of the aquarium wall are clamped by the slide rod 506 and the clamping rod 502 wrapped with the first gasket 601. The second gasket 602 on the back of the air pump body 1 is attached to the outer surface of the aquarium wall. After installation, the user can start and stop the device through the control button 2 on the front. The gas is output from the air pump connection port 3 on the top. The entire suspension process does not require tool adjustment. The clamping mechanism automatically adapts to the thickness of the aquarium wall and achieves silent fixation.
