[0014] III) Beneficial effects

[0015] Compared with the existing technology, the road noise reduction isolation belt has the following beneficial effects:

[0016] 1. The utility model is composed of a plurality of structures, which is not only convenient for installation and transportation, but also can replace damaged structures separately, thereby reducing the installation, transportation and maintenance costs. Specifically, the base is fixed on both sides of the road, and then the bottom plate is plugged into the side ends of the base, and the two are fixed by bolts passing through the second fixing holes, and then the support column is plugged into the upper end of the base, and the two are fixed by bolts passing through the first fixing holes, and multiple isolation plates are plugged into the track grooves of the support columns, and then the top cover is plugged into the upper ends of the support columns and locked by the fixing mechanism, thereby completing the installation. The base, the bottom plate, the support columns, and the isolation plates are all combined and connected, and they are in a disassembled state during transportation, so that they can be easily transported, and when a part is damaged, only it can be replaced, which solves the problem that the existing road noise reduction isolation belt is generally an integral type, which is not only difficult to transport and install, but also needs to be completely replaced when part of it is damaged, and its maintenance cost is high.

[0017] 2. The utility model is provided with a top cover, which can not only press and fix the installed isolation plate, but also play a partial sunshade and rainproof effect, thereby extending the service life of the device. Specifically, after the fixing rod of the top cover is inserted into the third fixing hole, an electric drill or a hexagonal wrench is inserted into the hexagonal hole at the side end of the two-way threaded rod to drive the two-way threaded rod to rotate, which cooperates with the moving ring to enable the moving ring to move, thereby enabling the moving ring to drive the fixing block to move into the oblique groove at the side end of the fixing rod. Since the side end of the fixing block is a bevel, the fixing block can press down the fixing rod through the oblique groove, thereby fixing the top cover while enabling the top cover to press down the isolation plate to fix it.

A support column 2 is arranged on the upper end of the base 1, and a first fixing hole 11 is opened in the base 1 and the support column 2. The support column 2 can be fixed to the upper end of the base 1 by passing a bolt through the first fixing hole 11.

[0028] Track grooves 3 are provided on both sides of the support column 2, and isolation plates 4 are provided on the side ends of the support column 2. The track grooves 3 are used to install the isolation plates 4. The side ends of the isolation plates 4 are fixedly connected with mounting heads 7, and the mounting heads 7 are slidably connected in the track grooves 3, which can make the installation of the isolation plates 4 more convenient. The outer shell of the isolation plates 4 is painted with sound-absorbing paint, corrosion-resistant paint, and waterproof paint to increase the sound insulation effect of the device and extend its service life. A reinforcement rod 13 is fixedly connected inside the isolation plates 4, and the reinforcement rod 13 can enhance the overall strength of the isolation plates 4, thereby improving the stability of the device. The isolation plates 4 are filled with sound insulation cotton 14, and the sound insulation cotton 14 is used to absorb and isolate the noise generated by vehicle driving.

[0029] A bottom plate 5 is provided at the side end of the support column 2, and the bottom plate 5 is used to reinforce the support column 2. A second fixing hole 12 is opened in the support column 2 and the bottom plate 5, and the bottom plate 5 and the support column 2 can be fixed together by using bolts passing through the second fixing hole 12.

[0030] A top cover 6 is provided on the uppermost isolation plate 4, which can not only press and fix the isolation plate 4, but also play a partial sunshade and rainproof effect. The upper end of the isolation plate 4 and the upper end of the bottom plate 5 are fixedly connected with a clamping strip 8, and the lower end of the isolation plate 4 and the lower end of the top cover 6 are provided with a clamping groove 9, and the clamping strip 8 can be clamped in the clamping groove 9, so that the connection between the bottom plate 5 and the isolation plate 4, and the isolation plate 4 and the top cover 6 can be made more stable.

[0031] A third fixing hole 15 is formed at the upper end of the support column 2, and a fixing rod 16 is fixedly connected to the lower end of the top cover 6. The fixing rod 16 is inserted into the third fixing hole 15 so that the top cover 6 can be connected to the support column 2. An inclined groove 17 is formed at the side end of the fixing rod 16.

[0032] A fixing mechanism 10 is provided between the support column 2 and the top cover 6, and the fixing mechanism 10 is used to clamp and fix the top cover 6. The fixing mechanism 10 includes a bidirectional threaded rod 18, and thread grooves are provided at both ends of the bidirectional threaded rod 18, and the thread directions of the two thread grooves are opposite. The bidirectional threaded rod 18 is transferred into the support column 2, and hexagonal holes 20 are provided at both ends of the bidirectional threaded rod 18. The hexagonal holes 20 are used to connect with an electric drill or a hexagonal wrench. The outer end of the bidirectional threaded rod 18 is threadedly connected to a moving ring 19, and the moving ring 19 is slidably connected In the support column 2, when the bidirectional threaded rod 18 rotates, the thread grooves at both ends thereof cooperate with the two movable rings 19 respectively, and the moving directions of the two movable rings 19 are always opposite. Fixed blocks 21 are fixedly connected on both sides of the movable rings 19. The side ends of the fixed blocks 21 are beveled edges, which are slidably connected in the beveled groove 17. When the movable ring 19 drives the fixed block 21 to move into the beveled groove 17, the beveled edges at its side ends act on the beveled groove 17, which will cause the fixed rod 16 to generate a downward pressing force, thereby enabling the top cover 6 to press down the isolation plate 4.

[0033] Working principle: fix the base 1 on both sides of the road, then insert the bottom plate 5 into the side end of the base 1, and pass the bolts through the second fixing hole 12 to connect and fix the two, then insert the support column 2 into the upper end of the base 1, and pass the bolts through the first fixing hole 11 to connect and fix the two, insert the isolation plate 4 from the upper end of the support column 2 into the track groove 3 through the mounting heads 7 at both ends, the slot 9 at the lower end of the first isolation plate 4 will be connected to the clip strip 8 at the upper end of the bottom plate 5, install the remaining isolation plates 4, each isolation plate 4 is connected to the slot 9 through the clip strip 8, so as to increase the stability of the isolation plate 4, insert the fixing rod 16 at the lower end of the top cover 6 into the third fixing hole 15 at the upper end of the support column 2, At this time, the slot 9 at the lower end of the top cover 6 will be connected to the clip 8 of the uppermost isolation plate 4, and then the top cover 6 will be fixed by the fixing mechanism 10, specifically, an electric drill or a hexagonal wrench is inserted into the hexagonal hole 20 at the side end of the two-way threaded rod 18, and then the two-way threaded rod 18 is driven to rotate, and the thread groove at its outer end will cooperate with the movable ring 19, so that the movable ring 19 moves in the support column 2, thereby driving the fixed block 21 to move into the inclined groove 17 at the side end of the fixed rod 16. Since the side end of the fixed block 21 is a bevel, the movement of the fixed block 21 into the bevel groove 17 can press down the fixed rod 16 through the bevel, so that while fixing the top cover 6, the top cover 6 can also press down the isolation plate 4 to fix it.
