[0037] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0038] According to an embodiment of this utility model, a road and bridge noise reduction device is provided, comprising: a mounting base 1 with a concave mounting groove 2 on the top for connecting to the side edge of a bridge or road; a mounting frame 3 with a snap-fit ​​part 4 at the bottom that fits into the concave mounting groove 2; a first positioning groove 5 on the side wall of the concave mounting groove 2; a first positioning block 6 retractably provided on the snap-fit ​​part 4 corresponding to the first positioning groove 5, the first positioning block 6 being fitted into the first positioning groove 5; a first switch assembly 7 disposed on the mounting frame 3; the adjusting end of the first switch assembly 7 being drivenly connected to the first positioning block 6 for driving the first positioning block 6 to retract into the snap-fit ​​part 4 or extend out of the snap-fit ​​part 4; and a noise reduction component 8 embedded in the mounting frame 3 for noise reduction.

[0039] It should be noted that the mounting frame 3 has an inner cavity for mounting the noise reduction component 8.

[0040] In this embodiment, during installation, the mounting base 1 is first fixed to the side edge of the bridge or road. Then, the first positioning block 6 is retracted into the snap-fit ​​part 4 by the first switch assembly 7. Next, the mounting frame 3 is inserted into the concave mounting groove 2 on the mounting base 1 through the snap-fit ​​part 4. Then, the first positioning block 6 is extended to the outside of the snap-fit ​​part 4 by the first switch assembly 7 again, so that the first positioning block 6 is snapped into the first positioning groove 5 for limiting, thus completing the installation. Then, the noise reduction component 8 on the mounting frame 3 forms a barrier to block sound and reduce noise. During disassembly, the first positioning block 6 is retracted into the snap-fit ​​part 4 by the first switch assembly 7 again, and then the snap-fit ​​part 4 of the mounting frame 3 is pulled out of the concave mounting groove 2. The overall structure is simple, convenient and quick, and can realize rapid installation and disassembly without the need for traditional fixing methods such as bolts and welding, which improves construction and maintenance efficiency. Moreover, the structure of the snap-fit ​​part 4 and the concave mounting groove 2 improves the overall stability.

[0041] Specifically, the inner cavity of the mounting frame 3 is rectangular and extends through the width of the concave mounting groove 2 to facilitate the installation of the noise reduction component 8.

[0042] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the mounting frame 3 has a first mounting cavity 9 along the vertical direction, the snap-fit ​​part 4 has a first mounting opening 10, and the first positioning block 6 is slidably disposed in the first mounting opening 10.

The first connecting plate 701 is slidably disposed in the first mounting cavity 9 along the axial direction of the first mounting opening 10. The first elastic element 702 is located on the side of the first connecting plate 701 away from the first mounting opening 10, and its two ends abut against the side wall of the first mounting cavity 9 and the first connecting plate 701, respectively. The first positioning block 6 is connected to the first connecting plate 701. The first push switch 703 is disposed on the side of the first connecting plate 701 away from the first elastic element 702. The mounting frame 3 has a first opening 11 corresponding to the first push switch 703, and the first push switch 703 extends to the outside of the mounting frame 3 through the first opening 11.

[0043] It should be noted that the first opening 11 is located above the mounting base 1 to facilitate pressing; the bottom of the first mounting cavity 9 extends to correspond to the position of the first mounting port 10; the first mounting port 10 is perpendicular to the first mounting cavity 9.

[0044] In this embodiment, by pressing the first press switch 703, the first connecting plate 701 can be driven to compress the first elastic element 702 in the first mounting cavity 9 and move in a direction away from the first mounting opening 10, so that the first connecting plate 701 drives the first positioning block 6 to retract into the snap-fit ​​part 4. At this time, it is convenient to embed the snap-fit ​​part 4 into the concave mounting groove 2 or to pull out the snap-fit ​​part 4 from the concave mounting groove 2. After the snap-fit ​​part 4 is embedded in the concave mounting groove 2, the first press switch 703 is released, and the first connecting plate 701 is driven to move towards the first mounting opening 10 under the elastic action of the first elastic element 702, so that the first connecting plate 701 drives the first positioning block 6 to extend to the outside of the snap-fit ​​part 4, so that the first positioning block 6 can be snapped into the first positioning groove 5 to achieve limit locking, prevent the mounting frame 3 from falling off, and improve stability.

[0045] Specifically, such as Figure 2 As shown, the top of the first mounting cavity 9 is connected to the top of the mounting frame 3, so as to facilitate the installation of the first switch assembly 7 into the first mounting cavity 9.

[0046] Specifically, such as Figure 4 As shown, the first positioning block 6, the first connecting plate 701, and the first push switch 703 are integrally formed, which improves the overall stability and service life.

[0047] Specifically, each first connecting plate 701 of the first switch assembly 7 can be provided with one, two or more first positioning blocks 6, and the side wall of the concave mounting groove 2 is provided with a corresponding number of first positioning grooves 5. The specific selection can be made according to actual needs to facilitate installation and improve stability.

[0048] In one embodiment, such as Figure 4 As shown, multiple first elastic elements 702 are provided, and the multiple first elastic elements 702 are evenly spaced along the vertical direction.

[0049] In this embodiment, a plurality of first elastic elements 702 are provided and are evenly distributed on the first connecting plate 701, so that the force is uniform and sufficient elastic force can be provided to make the first positioning block 6 engage in the first positioning groove 5 to ensure stability.

[0050] Specifically, such as Figure 4 As shown, the first push switch 703 is located in the middle of the first connecting plate 701 to ensure that the force is balanced when pressed, so as to drive the first connecting plate 701 to move.

[0051] In one embodiment, such as Figure 1 and Figure 3 As shown, the mounting base 1 has a connecting part 12 on its side; the connecting part 12 has a plurality of threaded holes 13 for connecting to the side edge of a bridge or road by bolts.

[0052] In this embodiment, by providing a connecting part 12 on the side of the mounting base 1 and providing a threaded hole 13 on the connecting part 12, the stability is improved by using bolts to pass through the threaded hole 13 and fix it to the side edge of the bridge or road during installation.

[0053] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the mounting frame 3 is provided with two sets of first switch assemblies 7 at both ends along the length of the concave mounting groove 2. The two sets of first switch assemblies 7 are symmetrically arranged along the width of the concave mounting groove 2. Each set of first switch assemblies 7 has a first positioning block 6 at its adjustment end.

[0054] In this embodiment, by symmetrically arranging the first switch assembly 7 in both the length and width directions of the concave mounting groove 2 on the mounting frame 3, and by providing a first positioning block 6 at the adjustment end of each set of first switch assemblies 7, the overall connection strength and stability are improved.

[0055] In one embodiment, such as Figure 1 and Figure 5 As shown, the road and bridge noise reduction device also includes a second switch assembly 14; the upper and lower sides or the left and right sides of the inner wall of the mounting frame 3 can be provided with a second positioning block 15, and the periphery of the noise reduction assembly 8 is provided with a second positioning groove 16 corresponding to the second positioning block 15, and the second positioning block 15 is adapted to be snapped into the second positioning groove 16; the adjustment end of the second switch assembly 14 is drivenly connected to the second positioning block 15, and is used to drive the second positioning block 15 to retract into the mounting frame 3 or extend to the outside of the inner wall of the mounting frame 3.

[0056] It should be noted that, as Figure 1 As shown, the left and right sides of the inner wall of the mounting frame 3 are in the length direction of the concave mounting groove 2, and the front and rear sides of the mounting frame 3 are in the width direction of the concave mounting groove 2.

[0057] In this embodiment, when installing the noise reduction component 8, the second positioning block 15 is driven to retract into the mounting frame 3 by the second switch component 14. Then, the noise reduction component 8 is embedded in the inner cavity of the mounting frame 3. Next, the second positioning block 15 is driven to extend to the outside of the inner side wall of the mounting frame 3 by the second switch component 14, so that the second positioning block 15 is engaged in the second positioning groove 16 for limiting, thereby completing the installation of the noise reduction component 8. When disassembling, the second positioning block 15 is driven to retract into the mounting frame 3 by the second switch component 14, and then the noise reduction component 8 can be removed from the mounting frame 3. The overall structure is simple, convenient and quick, and can realize rapid installation and disassembly without the need for traditional fixing methods such as bolts and welding, thereby improving construction and maintenance efficiency. The structure of the noise reduction component 8 being embedded in the inner cavity of the mounting frame 3, and the second positioning block 15 and the second positioning groove 16 provided on the upper and lower sides or left and right sides of the inner cavity side wall of the mounting frame 3, improve the overall stability.

[0058] In one embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, the mounting frame 3 has a second mounting cavity 17 along the horizontal direction, and a second mounting opening 18 is provided on the inner side wall of the mounting frame 3. The second positioning block 15 is slidably disposed in the second mounting opening 18, and the second mounting opening 18 communicates with the second mounting cavity 17. The second switch assembly 14 includes a second connecting plate 1401, a second elastic element 1402, and a second push switch 1403. The second connecting plate 1401 is slidably disposed in the second mounting cavity 17 along the axial direction of the second mounting opening 18. The second elastic element 1402 is located on the back of the second connecting plate 1401. The second positioning block 15 is connected to the second connecting plate 1401 and is located on one side of the second mounting port 18, with both ends abutting against the side wall of the second mounting cavity 17 and the second connecting plate 1401 respectively. The second pressing switch 1403 is located at the end of the second connecting plate 1401. The mounting frame 3 has a second opening 19 corresponding to the second pressing switch 1403. The second pressing switch 1403 extends to the outside of the mounting frame 3 through the second opening 19, and the second pressing switch 1403 and the second opening 19 are slidably connected in the axial direction of the second mounting port 18.

[0059] It should be noted that the first mounting cavity 9 is perpendicular to the second mounting cavity 17.

[0060] In this embodiment, by applying a force to the second push switch 1403 in a direction away from the second mounting opening 18, the second connecting plate 1401 can be driven to compress the second elastic member 1402 in the second mounting cavity 17 and move in a direction away from the second mounting opening 18. This causes the second connecting plate 1401 to retract the second positioning block 15 into the mounting frame 3. At this time, it is convenient to embed the noise reduction component 8 into the inner cavity of the mounting frame 3 or to pull out the noise reduction component 8 from the inner cavity of the mounting frame 3. After the noise reduction component 8 is embedded into the inner cavity of the mounting frame 3, the second push switch 1403 is released. Under the elastic action of the second elastic member 1402, the second connecting plate 1401 is driven to move towards the second mounting opening 18. This causes the second connecting plate 1401 to extend the second positioning block 15 to the outside of the inner side wall of the mounting frame 3, so that the second positioning block 15 can be engaged in the second positioning groove 16 to achieve limit locking, prevent the noise reduction component 8 from falling off, and improve stability.

A second opening 19 is provided on the mounting frame 3 for each second push switch 1403 so that both sides can be pressed at the same time and the force is balanced.

[0064] Specifically, the second mounting cavity 17 is provided along the width direction of the concave mounting groove 2.

[0065] Specifically, such as Figure 5 As shown, the second positioning block 15, the second connecting plate 1401, and the second push switch 1403 are integrally formed, which improves the overall stability and service life.

[0066] Specifically, each set of second switch components 14 can be provided with one, two or more second positioning blocks 15 on the second connecting plate 1401, and the noise reduction component 8 is provided with a corresponding number of second positioning slots 16 on its periphery.

[0068] In this embodiment, a plurality of second elastic elements 1402 are provided and are evenly distributed on the second connecting plate 1401, so that the force is uniform and sufficient elastic force can be provided to make the second positioning block 15 snap into the second positioning groove 16 to ensure stability.

[0069] In one embodiment, such as Figure 6 As shown, the noise reduction component 8 includes a dustproof plate 801, a honeycomb plate 802 and a sound-absorbing cotton plate 803 stacked sequentially from the outside to the inside. Each of the dustproof plate 801, the honeycomb plate 802 and the sound-absorbing cotton plate 803 is provided with a second positioning groove 16.

[0070] In this embodiment, a dustproof plate 801 is used to block dust from entering, a honeycomb plate 802 is used to disperse the sound wave path, and a sound-absorbing cotton plate 803 is used to absorb the remaining sound energy, thereby achieving a graded sound absorption effect and improving the overall noise reduction effect. Furthermore, the dustproof plate 801, honeycomb plate 802, and sound-absorbing cotton plate 803 are all provided with a second positioning groove 16, and the mounting frame 3 is provided with a second positioning block 15 for each second positioning groove 16, which facilitates layered assembly and individual disassembly, thereby improving the overall service life and maintenance efficiency.

[0071] In one embodiment, such as Figure 6 As shown, a dustproof plate 801 and a honeycomb plate 802 are symmetrically provided on both sides of the sound-absorbing cotton plate 803.

[0072] In this embodiment, a dustproof plate 801 and a honeycomb plate 802 are symmetrically provided on both sides of the sound-absorbing cotton plate 803, which can achieve sound insulation and noise reduction on both sides and further improve the noise reduction performance.

[0073] In one embodiment, such as Figure 1 and Figure 2 As shown, multiple sets of second switch assemblies 14 are symmetrically arranged on the upper and lower sides of the mounting frame 3, and each set of second switch assemblies 14 has a second positioning block 15 at its adjustment end.

[0074] It should be noted that the second positioning block 15 is vertically extendable and retractable on the inner side wall of the mounting frame 3.

[0075] In this embodiment, multiple sets of second switch assemblies 14 are provided on both the upper and lower sides of the mounting frame 3. Each set of second switch assemblies 14 is connected to a second positioning block 15. The second positioning blocks provided on the second switch assemblies 14 are also located on the upper and lower sides of the mounting frame 3, so as to improve the connection strength and stability, and facilitate the staggered arrangement of the first switch assemblies 7 along the length direction of the concave mounting groove 2, avoiding the occupation of a large space in the same position and mutual interference, improving space utilization and facilitating processing.

[0076] Specifically, each set of second switch assembly 14 has a number of second positioning blocks on its second connecting plate 1401 along its length direction corresponding to the dustproof plate 801, honeycomb plate 802 and sound-absorbing cotton plate 803, and a corresponding second positioning groove 16 on the dustproof plate 801, honeycomb plate 802 and sound-absorbing cotton plate 803, which facilitates installation and disassembly.

[0077] Specifically, the mounting frame 3 and the snap-fit ​​part 4 are integrally formed to improve structural strength.

[0078] Specifically, the first elastic element 702 is a compression spring.

[0079] Specifically, the second elastic element 1402 is a compression spring.

[0080] The specific installation and disassembly principle of the road and bridge noise reduction device provided in this embodiment is as follows: During installation, firstly, the mounting base 1 is fixed to the side edge of the bridge or road by passing bolts through the threaded hole 13. Then, by pressing the first press switch 703, the first connecting plate 701 is driven to compress the first elastic element 702 and drive the first positioning block 6 to retract into the snap-fit ​​part 4, while the snap-fit ​​part 4 is embedded into the concave mounting groove 2. Then, the first press switch 703 is released, and the first connecting plate 701, under the elastic action of the first elastic element 702, drives the first positioning block 6 to extend to the outside of the snap-fit ​​part 4 and snap into the first positioning groove 5, completing the installation of the mounting frame 3. Then, by applying force to the second press switch 1403, the second connecting plate 1401 is driven to compress the second elastic element 1402 and move away from the second mounting opening 18, so that the second connecting plate 1401 drives the second positioning block 15 to retract into the mounting frame 3. Then, the dustproof plate 801 and the honeycomb Plate 802 and sound-absorbing cotton plate 803 are sequentially embedded into the inner cavity of the mounting frame 3. Then, the second press switch 1403 is released, and the second connecting plate 1401 moves under the elastic action of the second elastic element 1402, driving the second positioning block 15 to extend to the outside of the inner side wall of the mounting frame 3 and engage in the second positioning groove 16 to complete the installation of the noise reduction component 8. The process can be reversed for disassembly. The overall structure is simple, convenient and quick, and can achieve rapid installation and disassembly without the need for traditional fixing methods such as bolts and welding, which improves construction and maintenance efficiency. Furthermore, the structure of the engaging part 4 and the concave mounting groove 2 improves the overall stability, achieving high efficiency, stability and flexibility throughout the entire process of construction, use and maintenance. It has good engineering applicability and promotion value, and solves the problem that existing road and bridge noise reduction devices use an integral cast-in-place structure or are fixed by bolts, welding and other methods, which are complex in installation procedures, cumbersome in overall construction process, and inconvenient for later replacement and maintenance.
