Abstract
Description
Technical Field
[0001] This utility model relates to the field of air compressor technology, specifically to an air compressor noise reduction device and an air compressor. Background Technology
[0002] An air compressor is a mechanical device used to convert air into a high-pressure state. It works by drawing in air, compressing it to reduce its volume and increase its pressure, and then storing the compressed air in an air tank. When an air compressor is working, it uses a power source such as an electric motor or internal combustion engine to drive the compression mechanism, and it generates considerable noise during operation.
[0003] In industrial production environments, air compressors, as core equipment for gas compression, require reduced operating noise. To effectively lower the noise level of air compressors, most widely used noise reduction devices employ highly enclosed enclosure structures for isolation. That is, by completely or partially enclosing the air compressor, a relatively sealed acoustic cavity is constructed, utilizing the sound-insulating materials and structural characteristics of the enclosure to block the noise generated by the air compressor.
[0004] However, most existing air compressor noise reduction enclosures are installed and fixed using fasteners such as bolts and nuts to ensure the enclosure's sealing and stability. However, they require specific tools for disassembly and assembly, making the process complex and time-consuming. Utility Model Content
[0005] To address the technical problems of complex disassembly and assembly and long time consumption of existing air compressor noise reduction devices, this utility model provides an air compressor noise reduction device and an air compressor. The soundproof cover is connected to the soundproof base by a plug-in connection, which has the characteristics of simple disassembly and assembly and high disassembly and assembly efficiency.
[0006] This utility model is achieved through the following technical solution:
[0007] In a first aspect, this utility model provides a noise reduction device for an air compressor, comprising: a soundproof base for mounting and supporting the air compressor body; a soundproof cover covering the soundproof base, with a connecting pin hole on the side wall; a locking pin slidably disposed on the soundproof base and capable of sliding into the connecting pin hole; and a linear drive assembly connected to the locking pin and capable of driving the locking pin to move along its own length direction.
[0008] The noise reduction device for air compressors provided by this utility model includes a soundproof base, a soundproof cover, a locking pin, and a linear drive assembly. The soundproof cover is mounted on the soundproof base and has a connecting pin hole on its side wall. The locking pin is slidably mounted on the soundproof base and can slide into the connecting pin hole. The linear drive assembly is connected to the locking pin. Thus, during installation, after the air compressor body is mounted on the soundproof base, the soundproof cover is mounted on the soundproof base. At the same time, the locking pin is driven by the linear drive assembly to move along its own length direction and insert into the connecting pin hole to lock the soundproof cover on the soundproof base. This makes the soundproof base and the soundproof cover form a relatively closed acoustic cavity, which can block and reduce the noise generated by the air compressor body during operation.
[0009] The system uses a linear drive assembly to move the locking lock along its own length and insert it into the connecting pin hole, thus locking the soundproof cover onto the soundproof base. When removal is required, simply use the linear drive assembly again to move the locking lock in the opposite direction along its own length to disengage it from the connecting pin hole, and the soundproof cover can be removed from the soundproof base, completing the disassembly and assembly of the soundproof cover. This eliminates the need for special tools to disassemble and remove multiple bolts, making disassembly and assembly simple and efficient.
[0010] In summary, the air compressor noise reduction device provided by this utility model has a soundproof cover connected to the soundproof base by a plug-in connection, which has the characteristics of simple disassembly and assembly and high disassembly and assembly efficiency.
[0011] In an optional embodiment of this application, each corner of the soundproof base is provided with a locking pin, and each corner of the soundproof cover is provided with a connecting pin hole, and the locking pin can be inserted into the corresponding connecting pin hole to ensure the stability of the connection between the soundproof cover and the soundproof base, and to prevent the soundproof cover from becoming loose during the operation of the air compressor.
[0012] In an optional embodiment of this application, the soundproof base is provided with an installation groove, and the locking pin is slidably engaged in the installation groove; each side of the soundproof base is provided with a connecting barrier, and the connecting barrier extends upward; wherein, the end of the locking pin can pass through the connecting barrier and slide into the corresponding connecting pin hole. On the one hand, providing the connecting barrier can ensure sufficient connection stability between the soundproof cover and the soundproof base; on the other hand, providing the installation groove can ensure the stability of the movement of the locking pin and avoid the locking pin getting stuck.
[0013] In an optional embodiment of this application, the mounting groove extends along the width direction of the soundproof base, and the upper side of the locking pin is a rack structure; the linear drive assembly includes two rotating rods, which extend along the length direction of the soundproof base, are mounted on the soundproof base, and are rotatable along their own axes; both ends of the two rotating rods are provided with drive gears, which mesh with the corresponding locking pins, so as to facilitate locking or unlocking by rotating the rotating rods to drive the locking pins to move, thus ensuring the convenience of operation.
[0014] In an optional embodiment of this application, a self-locking knob is fixedly connected to one end of the rotating rod. The self-locking knob can extend to the outside of the side wall of the soundproof cover so that the rotating rod can self-lock, thereby ensuring the stability of the locking pin's locked state.
[0015] In an optional embodiment of this application, a first soundproof ventilation window is provided in the middle of the soundproof base, and a second soundproof ventilation window is provided in the middle of the top of the soundproof cover. The first and second soundproof ventilation windows are arranged vertically to form convection, so that the acoustic cavity formed by the soundproof base and the soundproof cover has a certain degree of airtightness while ensuring that the air compressor can work effectively and dissipate heat.
[0016] In an optional embodiment of this application, a rain shield is also included, which covers the upper end of the soundproof cover at intervals, so as to block the second soundproof ventilation window by the rain shield, preventing rainwater from entering the acoustic cavity formed by the soundproof base and the soundproof cover, while also allowing the second soundproof ventilation window to perform normal ventilation and heat dissipation.
[0017] In an optional embodiment of this application, each corner of the top of the soundproof cover is provided with a connecting sleeve; each corner of the rainproof component is provided with a connecting rod, which can be inserted into the corresponding connecting sleeve; wherein, the connecting rod and the connecting sleeve are connected by connecting bolts to facilitate the detachable connection between the rainproof component and the soundproof cover.
[0018] In an optional embodiment of this application, each side of the rain shield is inclined downwards to ensure that rainwater can flow out quickly.
[0019] Secondly, this utility model provides an air compressor, including an air compressor body, which is installed in the aforementioned air compressor noise reduction device to achieve sound insulation and noise reduction, and also facilitates the disassembly and assembly of the air compressor body.
[0020] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0021] 1. The air compressor noise reduction device provided by this utility model includes a soundproof base, a soundproof cover, a locking pin, and a linear drive assembly. The soundproof cover is mounted on the soundproof base and has a connecting pin hole on its side wall. The locking pin is slidably mounted on the soundproof base and can slide into the connecting pin hole. The linear drive assembly is connected to the locking pin. Thus, during installation, after the air compressor body is mounted on the soundproof base, the soundproof cover is placed on the soundproof base. At the same time, the locking pin is driven by the linear drive assembly to move along its own length direction and insert into the connecting pin hole. The soundproof cover is locked to the soundproof base inside the pin hole, so that the soundproof base and the soundproof cover form a relatively closed acoustic cavity, which can block and reduce the noise generated by the air compressor body during operation. When it needs to be removed, simply drive the locking lock to move in the opposite direction along its own length through the linear drive component to disengage the locking lock from the connecting pin hole, and the soundproof cover can be removed from the soundproof base, thus completing the disassembly and assembly of the soundproof cover. There is no need to use special tools to disassemble and remove multiple bolts, making disassembly and assembly simple and efficient.

[0036] Example 1
[0037] Combination Figure 1 and Figure 2 This utility model provides a noise reduction device for an air compressor, comprising: a soundproof base 10 for mounting and supporting the air compressor body; a soundproof cover 20 covering the soundproof base 10, with a connecting pin hole 21 on its side wall; a locking pin 30 slidably disposed on the soundproof base 10 and capable of sliding into the connecting pin hole 21; and a linear drive assembly connected to the locking pin 30, capable of driving the locking pin 30 to move along its own length direction.
[0038] It is understood that each corner of the soundproof base 10 is provided with a locking pin 30, and each corner of the soundproof cover 20 is provided with a connecting pin hole 21. The locking pin 30 can be inserted into the corresponding connecting pin hole 21 to ensure the stability of the connection between the soundproof cover 20 and the soundproof base 10, and to prevent the soundproof cover 20 from loosening during the operation of the air compressor. Furthermore, each foot of the soundproof base 10 is provided with a foot support 14, creating a gap between the bottom of the soundproof base 10 and the installation ground.
[0039] Combination Figure 3 The soundproof base 10 is provided with an installation groove 11, and the locking pin 30 is slidably engaged in the installation groove 11. Each side of the soundproof base 10 is provided with a connecting barrier 12, which extends upward. The end of the locking pin 30 can pass through the connecting barrier 12 and slide into the corresponding connecting pin hole 21. On the one hand, the connecting barrier 12 can ensure sufficient connection stability between the soundproof cover 20 and the soundproof base 10. On the other hand, the installation groove 11 can ensure the stability of the movement of the locking pin 30 and prevent the locking pin 30 from getting stuck.
[0040] Specifically, the mounting groove 11 extends along the width direction of the soundproof base 10, and the upper side of the locking pin 30 is a rack and pinion structure; the linear drive assembly includes two rotating rods 40, which extend along the length direction of the soundproof base 10, are mounted on the soundproof base 10, and can rotate along their own axis; both ends of the two rotating rods 40 are provided with drive gears 41, which mesh with the corresponding locking pins 30, so as to drive the locking pins 30 to move by rotating the rotating rods 40, thereby achieving locking or unlocking and ensuring the convenience of operation.
[0041] In this embodiment, a self-locking knob 42 is fixedly connected to one end of the rotating rod 40. The self-locking knob 42 can extend to the outside of the side wall of the soundproof cover 20 (a slot 23 adapted to the self-locking knob 42 is provided at the corresponding position of the soundproof cover 20), so that the rotating rod 40 can self-lock, thereby ensuring the stability of the locking pin 30 in the locked state. It is known that the self-locking knob 42 can generate a holding torque / resistance at the target position. This torque is greater than the expected disturbance torque (vibration, contact, etc.), thereby achieving position stability. It is mainly achieved by using spring force to generate mechanical interlocking (steel ball into groove, pawl locking ratchet) or friction force. These are existing mature products that can be purchased directly, and will not be described in detail in this embodiment.
[0042] It should be understood that the soundproof base 10 is provided with a first soundproof ventilation window 13 in the middle, and the soundproof cover 20 is provided with a second soundproof ventilation window 22 in the middle of the top. The first soundproof ventilation window 13 and the second soundproof ventilation window 22 are arranged vertically to form convection, so that the acoustic cavity formed by the soundproof base 10 and the soundproof cover 20 has a certain degree of airtightness while ensuring that the air compressor can work effectively and dissipate heat.
[0043] It is understood that this embodiment also includes a rain shield 50, which covers the upper end of the soundproof cover 20 at intervals. The rain shield 50 blocks the second soundproof ventilation window 22, preventing rainwater from entering the acoustic cavity formed by the soundproof base 10 and the soundproof cover 20, while also allowing the second soundproof ventilation window 22 to ventilate and dissipate heat normally. The soundproof ventilation window can be a ventilable sound-absorbing and vibration-damping component such as a micro-perforated plate, polyester fiber sound-absorbing cotton, or mineral wool / rock wool, or it can be a structure with staggered labyrinthine flow channels.
[0044] Combination Figure 4 Each corner of the top of the soundproof cover 20 is provided with a connecting sleeve 24; each corner of the rainproof component 50 is provided with a connecting rod 51, which can be inserted into the corresponding connecting sleeve 24; wherein, the connecting rod 51 and the connecting sleeve 24 are connected by a connecting bolt 60, so as to detachably connect the rainproof component 50 and the soundproof cover 20.
[0045] Generally, the rain shield 50 is inclined downwards on each side to ensure that rainwater can flow out quickly.
[0046] In summary, the air compressor noise reduction device provided in this embodiment includes a sound insulation base 10, a sound insulation cover 20, a locking pin 30, and a linear drive assembly. The sound insulation cover 20 is mounted on the sound insulation base 10 and has a connecting pin hole 21 on its side wall. The locking pin 30 is slidably mounted on the sound insulation base 10 and can slide into the connecting pin hole 21. The linear drive assembly is connected to the locking pin 30 in a transmission manner.
[0047] During installation, after the air compressor body is installed on the soundproof base 10, the soundproof cover 20 is placed on the soundproof base 10. At the same time, the locking lock is driven by the linear drive component to move along its own length direction and insert into the connecting pin hole 21 to lock the soundproof cover on the soundproof base 10. This makes the soundproof base 10 and the soundproof cover 20 form a relatively closed acoustic cavity, which can block and reduce the noise generated by the air compressor body during operation.
[0048] When removal is required, simply drive the locking lock to move in the opposite direction along its own length again through the linear drive component, and the locking lock will be disengaged from the connecting pin hole 21. The soundproof cover 20 can then be removed from the soundproof base 10, completing the disassembly and assembly of the soundproof cover 20. This does not require the use of special tools to disassemble and remove multiple bolts, making disassembly and assembly simple and efficient.
[0049] In this embodiment, the soundproof base 10 and the soundproof cover 20 are detachably connected, forming a relatively closed cavity to insulate the air compressor. Rotating the self-locking knob can drive the rotating rod 40 to rotate, which in turn locks the soundproof cover 20 with the locking pin 30. The self-locking effect of the self-locking knob ensures the stability of the locking of the soundproof cover 20. Compared with the prior art, while ensuring the stability of the sealed connection between the soundproof base 10 and the soundproof cover 20, disassembly and assembly do not require specific tools and professional skills, reducing the complexity of operation and time costs.
[0050] Furthermore, by rotating the self-locking knob, the rotating rod 40 is rotated, which in turn drives the gear to rotate. This causes the rack-mounted locking pin 30 to slide along the mounting groove 11. As it moves, it can penetrate the soundproof base 10 and insert into the soundproof cover 20 to lock it in place. This completes the connection between the soundproof base 10 and the soundproof cover 20. The connection is easy to make and disassemble. Moreover, the slot 23 can be used to match the self-locking knob without affecting the connection between the soundproof base 10 and the soundproof cover 20.
[0051] In addition, the air circulation through the cooperation of the first soundproof ventilation window 13 and the second soundproof ventilation window 22 can realize the heat dissipation of the soundproof device. The air intake channel is reserved by the installed foot support 14. The rain shield 50 can be installed by the cooperation of the connecting sleeve 24 and the connecting rod 51, so that it can be used outdoors. At the same time, an exhaust channel is reserved between the soundproof cover 20 and the rain shield 50 to facilitate the heat dissipation.
[0052] In summary, the air compressor noise reduction device provided in this embodiment has a soundproof cover 20 connected to the soundproof base 10 via a plug-in connection, which features simple assembly and disassembly and high assembly and disassembly efficiency.
