Description

Technical Field

[0001] This utility model belongs to the field of soundproof cover technology, specifically an integrated composite soundproof cover structure of a porous sound-absorbing layer and a vibration isolation frame. Background Technology

[0002] An integrated composite soundproof enclosure with a porous sound-absorbing layer and a vibration-isolation frame typically consists of a porous sound-absorbing layer, a vibration-isolation frame, and an outer shell. The porous sound-absorbing layer is installed on the inner side of the vibration-isolation frame, while the outer shell is installed on the outer side. The porous sound-absorbing layer has a good absorption effect on mid-to-high frequency sound waves, which can effectively reduce noise reflection and reverberation inside the enclosure. The vibration-isolation frame reduces vibration transmission, thereby reducing structural noise caused by vibration. The combination of the two improves the overall sound insulation performance.

[0003] Currently, the outer shell of the composite soundproof enclosure is usually fixed to the outside of the vibration isolation frame with multiple bolts, which requires multiple operations and makes the operation quite cumbersome. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figure 1-2 This utility model relates to an integrated composite soundproof cover structure of a porous sound-absorbing layer and a vibration-damping frame, including a cover 1. An outer ring 3 is fixedly connected to the outer side of the cover 1. A metal frame 9 is provided on the inner side of the cover 1, which supports the entire soundproof cover. An outer ring 4 is fixedly connected to the outer side of the metal frame 9. The outer ring 3 is located at the top of the outer ring 4. Multiple rubber vibration isolators 5 are provided at the bottom of the outer ring 4. By setting the rubber vibration isolators 5, vibration transmission can be reduced. Glass wool 8 is provided on the inner side of the metal frame 9, which can absorb sound. A fixing mechanism 2 is provided between the outer ring 3 and the outer ring 4.

[0024] Specifically, by Figure 3The fixing mechanism 2 includes a U-shaped plate 201 located at the top of the outer ring 4. A guide post 2011 is fixedly connected to the inner side of the U-shaped plate 201. Two guide blocks 202 are symmetrically and movably sleeved on the outer side of the guide post 2011. Positioning rods 203 are fixedly connected to the sides of the two guide blocks 202 that are far apart from each other. The outer ring 3 is provided with a groove 2010. The outer ring 3 is sleeved on the outer side of the U-shaped plate 201 through the groove 2010. Two positioning rings 204 are symmetrically fixedly connected to the inner side of the groove 2010. The two positioning rods 203 are respectively inserted into the two positioning rings 204. The U-shaped plate 201 is provided with a sliding groove 2012. The two guide blocks 202 slide in the sliding groove 2012. The U-shaped plate 201 is fixedly connected to a sleeve block 209 on its inner side. The sleeve block 209 is fixedly sleeved on the outer middle of the guide post 2011. The top of the sleeve block 209 is rotatably connected to a screw rod 207. The top of the screw rod 207 is fixedly connected to a turntable 206. The outer side of the screw rod 207 is threadedly sleeved with a threaded sleeve 208. The outer side of the threaded sleeve 208 is fixedly connected to a limit rod 2014. The outer side of the sleeve block 209 is provided with a limit groove 2013. The limit rod 2014 is slidably connected to the limit groove 2013. The outer side of the threaded sleeve 208 is symmetrically rotatably connected to two movable rods 205. The ends of the two movable rods 205 away from the threaded sleeve 208 are rotatably connected to two guide blocks 202 respectively.

[0025] In use, the cover 1 is first placed on the outside of the metal frame 9, with the outer ring 3 at the top of the outer ring 4, so that the outer ring 3 is placed on the outside of the U-shaped plate 201 through the groove 2010. Then, the turntable 206 is rotated, which drives the screw 207 to rotate. Since the limiting rod 2014 is slidably connected to the limiting groove 2013, the screw sleeve 208 moves along the length of the screw 207. Then, the two movable rods 205 drive the two guide blocks 202 to slide along the guide post 2011 and the slide groove 2012 respectively. At the same time, the two positioning rods 203 move away from each other until they are inserted into the two positioning rings 204 respectively, fixing the outer ring 3 and the outer ring 4. Finally, the cover 1 is quickly installed.

[0026] Specifically, by Figure 4 As shown, the outer side of the cover 1 is provided with an outer cylinder 6, and multiple auxiliary handles 10 are fixedly connected to the outer side of the outer cylinder 6. By setting the auxiliary handles 10, it is easy to rotate the outer cylinder 6. The bottom of the outer cylinder 6 is fixedly connected with a limit ring 12, which abuts against the top of the threaded sleeve 208. The inner side of the outer cylinder 6 is provided with an internal thread 11, and the outer side of the cover 1 is provided with an external thread 7 that matches the internal thread 11. The outer cylinder 6 is threadedly sleeved on the outer side of the cover 1 through the internal thread 11 and the external thread 7. The limit ring 12 does not contact the external thread 7 to avoid wear of the external thread 7.

[0027] In use, first rotate the outer cylinder 6 using the auxiliary handle 10. Since the outer cylinder 6 is threaded onto the outside of the cover 1, the outer cylinder 6 moves downward while rotating, and drives the limiting ring 12 to move downward until the limiting ring 12 abuts against the top of the threaded sleeve 208, preventing the positioning rod 203 from disengaging from the positioning ring 204, and finally improving the stability of the cover 1 during installation.
