Technical Field

[0001] The utility model relates to the technical field of damping structures, in particular to a rubber part damping structure for a sound barrier. Background Art

[0002] Sound barriers are mainly used for sound insulation and noise reduction of roads, highways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation, and the latter is a more effective sound insulation method. It refers to a wall-like structure set beside railways and roads to reduce the impact of traffic noise on nearby residents. The sound insulation wall is also called a sound barrier.

[0003] In the existing sound barrier structure, the rubber part damping structure is mostly connected to other components inside the sound barrier by an adhesive method. However, during the daily use of the sound barrier, as time goes by, under the repeated action of factors such as vibration generated by vehicle driving and wind force, it is very likely that the internal rubber part damping will fall off or become loose, affecting the overall performance of the sound barrier. Therefore, this application proposes a rubber part damping structure for a sound barrier. Summary of the Invention

[0030] Embodiment

[0031] As Figure 1 As shown in Fig. -3, a rubber damping structure for a sound barrier proposed by the present utility model includes a sound barrier body 1, and further includes a rectangular groove 2 opened in the sound barrier body 1. A cavity 3 is arranged in the sound barrier body 1. A through port 4 communicating with the cavity 3 is opened on the inner wall of the rectangular groove 2. The through port 4, the rectangular groove 2, and the cavity 3 are an integrally connected space, facilitating the subsequent connection of the rubber damping structure.

[0032] In addition, a rubber damping plate 5 is arranged in the rectangular groove 2. A fixing block 11 is fixedly connected to the side of the rubber damping plate 5 away from the cavity 3. A sealing strip 12 is arranged on the fixing block 11. The sealing strip 12 can be connected to one side of the outer wall of the sound barrier body 1. When the rubber damping plate 5 is completely inserted into the rectangular groove 2 for connection, at this time, the sealing strip 12 can better adhere to the outer wall of the sound barrier body 1, making its sealing effect better.

[0033] In addition, a plurality of shock-absorbing columns 10 are fixedly installed on both sides of the inner wall of the rectangular groove 2 at the through port 4. A hole groove for accommodating the shock-absorbing columns 10 is opened on the rubber damping plate 5. When the rubber damping plate 5 completely enters the rectangular groove 2, at this time, the shock-absorbing columns 10 also enter the hole groove, connecting it with the rubber damping plate 5 and improving the overall shock-absorbing effect.

[0034] As Figure 3 As shown in Fig. -5, an insertion block 6 is fixedly connected to the side of the rubber damping plate 5 close to the cavity 3. A card slot 7 matching the insertion block 6 is arranged on the inner wall of the cavity 3. By making the insertion block 6 enter the through port 4 and successfully snap into the card slot 7, the preliminary connection and fixation of the rubber damping plate 5 are completed.

[0035] Furthermore, the device further includes a stabilizing device. The stabilizing device is arranged in the cavity 3 for preventing the rubber damping plate 5 from loosening. The stabilizing device includes mounting seats 13 fixedly installed on both sides of the inner wall of the cavity 3. Support blocks 14 are fixed to the mounting seats 13. Springs 15 are fixedly installed on the support blocks 14. The springs 15 are fixedly connected to a clamping plate 16.

[0036] It should be noted that one side section of the pallet 16 is specifically in an arc structure. During the process of inserting the insertion block 6 into the card slot 7, the two sides of the insertion block 6 will squeeze the arc surfaces of the two pallets 16, causing the pallets 16 to move and the spring 15 to compress. After inserting into the card slot 7, the external force disappears. At this time, the spring 15 will reset and drive the pallets 16 to resist against both sides of the fixed insertion block 6, making its connection more firm and stable;

[0037] Furthermore, arc-shaped limiting grooves 9 are provided on both sides of the inner wall of the rectangular groove 2. Arc-shaped limiting blocks 8 that match the arc-shaped limiting grooves 9 are connected to both sides of the rubber damping plate 5. The arc-shaped limiting blocks 8 are snapped into the arc-shaped limiting grooves 9, so that the left and right directions of the rubber damping plate 5 are also limited. With the pressing of the pallets 16, the connection stability is significantly improved;

[0038] It is worth mentioning that multiple groups of noise elimination channels 17 are provided inside the rubber damping plate 5. Multiple groups of protrusions 19 are provided on the inner surface of the noise elimination channels 17. A sound absorption layer 18 is connected inside the noise elimination channels 17. The multiple groups of protrusions 19 can change the reverse direction of the sound wave movement and cooperate with the bending setting of the noise elimination channels 17, enabling the sound waves to be reflected multiple times and the multiple sound absorptions to be superimposed, making the noise reduction effect remarkable.

[0039] Working principle: Press the fixed block 11 to make the rubber damping plate 5 enter the inside of the rectangular groove 2, and make the insertion block 6 enter the cavity 3 through the through port 4. Press the fixed block 11 to insert the insertion block 6 into the card slot 7. During this process, the insertion block 6 squeezes the arc-shaped end faces of the two pallets 16, compressing the spring 15, and the pallets 16 move backward until the insertion block 6 is successfully snapped into the card slot 7. When the pressing external force disappears, the spring 15 resets and drives the pallets 16 to press against both sides of the insertion block 6, and cooperates with the arc-shaped limiting blocks 8 to be respectively snapped into the arc-shaped limiting grooves 9 to realize the limitation in the left and right horizontal directions, making the connection of the rubber damping plate 5 more stable and preventing the slippage or detachment of the rubber damping part. In addition, the multiple curved noise elimination channels 17 provided cooperate with the protrusions 19, enabling the sound waves to be reflected multiple times and the multiple sound absorptions to be added, significantly improving the noise reduction effect.

[0040] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
