A sound wave resonance noise reduction structure for a pneumatic vibrator

Abstract

This utility model relates to the field of noise reduction technology, and in particular to a sound wave resonance noise reduction structure for a pneumatic vibrator. It mainly addresses the problem of the need for periodic bolt tightening, which affects the efficiency of the pneumatic vibrator. The proposed technical solution includes a vibrator body with a connection port fixedly connected to its top, and a mounting screw slidably connected inside the vibrator body. This utility model uses a spring outside a telescopic tube, connected to a lower pressure plate fixed to the telescopic tube. Even if the mounting screw becomes loose, the spring can still push the lower pressure plate to engage with the mounting screw, ensuring that the mounting screw does not wobble and generate noise in the vibrator body. A positioning sleeve is fitted outside the mounting screw, allowing the positioning block to restrict the rotation of the rotating block and the positioning sleeve, ensuring that the mounting screw does not rotate. This reduces the noise generated by the vibrator body during use and improves the working efficiency of the vibrator body.

Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, and in particular to an acoustic resonance noise reduction structure for a pneumatic vibrator. Background Technology

[0002] Noise reduction is a method of controlling the intensity of noise along the propagation path. The sound absorption effect of objects is universal. The sound absorption effect is not only related to the sound-absorbing material, but also to the selected sound-absorbing structure. Noise reduction structures are needed in pneumatic vibrators.

[0003] The existing pneumatic vibrator is installed at the location where vibration is needed. An input pipe is inserted into one side of the pneumatic vibrator, and vibration is achieved through gas compression. Meanwhile, gas is discharged at another location in the input pipe of the pneumatic vibrator to reduce noise, thus avoiding the generation of excess noise during the gas compression input and output process.

[0004] However, during pneumatic vibration, the bolts at the connection points of the pneumatic vibrator may loosen, resulting in unnecessary noise. Regular tightening of the bolts is necessary, affecting the efficiency of the pneumatic vibrator. Therefore, this invention proposes an acoustic resonance noise reduction structure for pneumatic vibrators. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background art where bolts at the connection points of a pneumatic vibrator loosen during vibration, resulting in unnecessary noise and requiring periodic tightening, which affects the efficiency of the pneumatic vibrator. This invention proposes a sound wave resonance noise reduction structure for pneumatic vibrators.

[0006] The technical solution of this utility model is as follows: a sound wave resonance noise reduction structure for a pneumatic vibrator, comprising a vibrator body, a connection port fixedly connected to the top of the vibrator body, an installation screw slidably connected inside the vibrator body, a telescopic tube fixedly connected to the vibrator body near the installation screw, a lower pressure plate fixedly connected to the end of the telescopic tube away from the vibrator body, and the installation screw slidably connected inside the telescopic tube and the lower pressure plate.

[0007] A spring is provided on the outside of the telescopic tube. One end of the spring is fixedly connected to the vibrator body near the telescopic tube, and the other end of the spring away from the vibrator body is fixedly connected to the lower pressure plate near the telescopic tube.

[0008] A positioning sleeve is fitted around the outside of the mounting screw near the lower pressure plate. The positioning sleeve abuts against the top of the lower pressure plate, and a positioning component is provided on the outside of the positioning sleeve.

[0009] Optionally, the positioning component includes a rotating block, which is fixedly connected to the outside of the positioning sleeve. Multiple rotating blocks are arranged in a circumferential array, and a positioning block is abutted against the opposite side of the rotating block.

[0010] Optionally, the positioning blocks are arranged in a circular array in multiple groups, and a positioning ring is fixedly connected to the end of the positioning block away from the rotating block, and the positioning ring abuts against the top of the lower pressure plate.

[0011] Optionally, a positioning tube is slidably connected to the outside of the positioning ring, the positioning ring is slidably connected inside the positioning tube, and a sliding component is provided inside the positioning ring.

[0012] Optionally, the sliding component includes a slide groove, which is formed inside the positioning tube. Multiple slide grooves are arranged in a circumferential array. A slider is slidably connected inside the slide groove, and the slider is fixedly connected to the outside of the positioning ring.

[0013] Optionally, an embedding groove is provided on one side of the vibrator body, and an embedding block is fitted inside the embedding groove. The embedding groove and the embedding block are arranged in a "T" shape.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This invention employs a spring outside the telescopic tube, connecting the spring to the lower pressure plate fixed to the telescopic tube. Even if the mounting screw becomes loose, the spring can still push the lower pressure plate to engage with the mounting screw, ensuring that the mounting screw does not wobble and cause noise in the vibrator body. A positioning sleeve is fitted over the mounting screw, allowing the positioning block to restrict the rotating block and the positioning sleeve, ensuring that the mounting screw does not rotate.

[0030] Example

[0031] like Figures 1 to 3 As shown, the present invention proposes a sound wave resonance noise reduction structure for a pneumatic vibrator, comprising a vibrator body 1, a connection port 2 fixedly connected to the top of the vibrator body 1, through which gas can be input into the vibrator body 1 for vibration, a mounting screw 6 slidably connected inside the vibrator body 1, the mounting screw 6 for mounting the vibrator body 1, a telescopic tube 3 fixedly connected to the vibrator body 1 near the mounting screw 6, the telescopic tube 3 being extendable and retractable, a lower pressure plate 4 fixedly connected to the end of the telescopic tube 3 away from the vibrator body 1, and the mounting screw 6 slidably connected... Inside the telescopic tube 3 and the lower pressure plate 4, the mounting screw 6 passes through the telescopic tube 3 and the lower pressure plate 4 for installation; a spring 5 is provided on the outside of the telescopic tube 3, one end of the spring 5 is fixedly connected to the vibrator body 1 near the side of the telescopic tube 3, and the other end of the spring 5 away from the vibrator body 1 is fixedly connected to the lower pressure plate 4 near the side of the telescopic tube 3. The spring 5 can buffer the telescopic tube 3; a positioning sleeve 7 is fitted on the outside of the mounting screw 6 near the position of the lower pressure plate 4. The positioning sleeve 7 abuts against the top of the lower pressure plate 4. The positioning sleeve 7 can limit the rotation of the mounting screw 6. A positioning component is provided on the outside of the positioning sleeve 7.

[0032] For further details, please refer to Figure 2 and Figure 3The positioning component includes rotating blocks 8, which are fixedly connected to the outside of the positioning sleeve 7. Multiple sets of rotating blocks 8 are arranged in a circular array. The multiple structures of the rotating blocks 8 can restrict the rotation of the mounting screw 6 at different angles. A positioning block 9 abuts against one side of each rotating block 8. Multiple sets of positioning blocks 9 are arranged in a circular array. A positioning ring 10 is fixedly connected to the end of each positioning block 9 away from the rotating blocks 8. The positioning ring 10 embeds the positioning blocks 9 between the rotating blocks 8, thereby positioning the positioning sleeve 7. The positioning ring 10 abuts against the top of the lower pressure plate 4, and the outer surface of the positioning ring 10 is slidably connected... A positioning tube 19 is connected, and a positioning ring 10 is slidably connected inside the positioning tube 19. The positioning ring 10 and the lower pressure plate 4 slide inside the positioning tube 19 for more stable lifting and lowering. A sliding component is provided inside the positioning ring 10. The sliding component includes a slide groove 11, which is opened inside the positioning tube 19. There are multiple sets of slide grooves 11 arranged in a circumferential array. A slider 12 is slidably connected inside the slide groove 11. The positioning ring 10 can slide inside the slide groove 11 and the positioning tube 19 by relying on the slider 12. The slider 12 is fixedly connected to the outside of the positioning ring 10 and can restrict the positioning ring 10.

[0033] For further details, please refer to Figure 4 and Figure 5 The vibrator body 1 has an embedded groove 13 on one side, and an embedded block 18 is fitted inside the embedded groove 13. The embedded groove 13 and the embedded block 18 are arranged in a "T" shape. The embedded block 18 can reduce the noise of the vibrator body 1 striking the installation position. A shock-absorbing pad 14 is fixedly connected to the side of the embedded block 18 away from the embedded groove 13. The shock-absorbing pad 14 abuts against the side of the vibrator body 1. The shock-absorbing pad 14 and the embedded block 18 fit better in the installation position. A rotating plate 15 abuts against one side of the embedded groove 13. A rotating shaft 16 is rotatably connected inside the rotating plate 15. The rotating shaft 16 is fixedly connected to the outside of the vibrator body 1. The rotating shaft 16 can prevent the embedded block 18 from falling out of the embedded groove 13. A positioning screw 17 is rotatably connected between the rotating plate 15 and the inside of the vibrator body 1. The positioning screw 17 can fix the position of the embedded block 18.

[0034] In this embodiment, during use, the positioning screw 17 is first removed from the vibrator body 1 and the rotating plate 15. Then, the rotating plate 15 can be rotated by the rotating shaft 16, thus exposing the position of the embedding groove 13. The rotating block 8 can then be installed along the position of the embedding groove 13. Then, the rotating plate 15 is rotated again to install the positioning screw 17 inside the rotating plate 15, thereby positioning the rotating plate 15 and preventing excessive noise when the vibrator body 1 vibrates.

[0035] After the shock-absorbing pad 14 and the embedded block 18 are installed, the mounting screw 6 can be passed through the vibrator body 1 along the lower pressure plate 4 and the telescopic tube 3. The vibrator body 1 can be installed using the mounting screw 6. Even if the mounting screw 6 becomes loose when the vibrator body 1 vibrates, the telescopic tube 3 and the spring 5 will push the lower pressure plate 4 to remain in contact with the mounting screw 6. This ensures that even if the mounting screw 6 becomes loose, the buffer of the spring 5 can still absorb and weaken the noise of the mounting screw 6.

[0036] After the installation screw 6 is installed, the positioning sleeve 7 can be put on the outside of the installation screw 6 so that the positioning sleeve 7 abuts against the lower pressure plate 4. Then, the positioning ring 10 is inserted into the positioning tube 19 and the positioning ring 10 slides along the inside of the slide groove 11 by the slider 12. In this way, the positioning ring 10 can be installed into the positioning tube 19.

[0037] When the vibrator body 1 vibrates, the mounting screw 6 shakes. The positioning block 9 inside the positioning ring 10 can still restrict the rotating block 8, thus ensuring that the mounting screw 6 will not rotate with the positioning sleeve 7 and the rotating block 8. This ensures the stability of the mounting screw 6 during installation and also ensures that even if the rotating block 8 or the positioning ring 10 breaks, the spring 5 can still keep the lower pressure plate 4 in contact with the mounting screw 6, thereby ensuring that the noise is reduced.

[0038] It should be noted that this device uses a spring 5 outside the telescopic tube 3, which is connected to the lower pressure plate 4 fixed to the telescopic tube 3. In this way, even if the mounting screw 6 is loose, the spring 5 can still push the lower pressure plate 4 to fit against the mounting screw 6, thereby ensuring that the mounting screw 6 will not shake and cause noise in the vibrator body 1. The positioning sleeve 7 is fitted outside the mounting screw 6, and the positioning block 9 restricts the rotating block 8 and the positioning sleeve 7, ensuring that the mounting screw 6 will not rotate, reducing the noise generated by the vibrator body 1 during use and improving the working efficiency of the vibrator body 1.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
