Description

Technical Field

[0001] The utility model relates to the field of noise reduction products, in particular to a noise reduction barrier using noise reduction paint. Background Art

[0002] For the existing noise reduction barrier application scenarios, the products available are quite diverse. Depending on the specific needs of noise reduction and sound insulation, sound-absorbing recording studios, HIFI rooms, etc., the materials and settings used will vary greatly. Common materials include foam, cardboard, rock wool, fiberglass, polyester fiber and rock wool, etc. At the same time, the corresponding materials in the filling board have a relatively short lifespan and need to be replaced regularly.

[0003] At the same time, if conditions permit, a hollow area will be set up inside the barrier to serve as a sound bridge. At the same time, there will be components on both sides of the sound bridge that are not rigidly connected, which can effectively utilize the elastic layer of the air layer to achieve a sound insulation effect.

[0004] Current sound insulation products will also spray sound-absorbing coatings on the outside of the barrier, which are made of bio-fiber, mineral fiber, etc. as the main raw materials combined with other fire retardants, moisture-proof, and enzyme-resistant agents. At the same time, they are sprayed together with adhesives through professional machinery and attached to the inner roof and walls to form a 2-10mm thick, apparently porous cotton-like coating material, which can effectively enhance the sound insulation effect.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is merely used to describe a novel optical lens holder or several specific embodiments of the present invention, and does not strictly limit the scope of protection specifically claimed by the present invention.

[0023] like Figure 1-Figure 5 As shown, a noise reduction barrier using noise reduction paint includes an end frame 1, a porous plate 2, a filling plate 3, a flexible connecting block 4, and a rotating wheel 5; the two end frames 1 are rectangular, and two porous plates 2 are arranged between the two end frames 1, each end frame 1 is connected to the top and bottom ends of the two porous plates 2, two filling plates 3 are arranged between the two porous plates 2, each filling plate 3 is connected to a porous plate 2, and the two filling plates 3 do not contact each other, and a certain space is reserved between the two filling plates 3, and a flexible connecting block 4 is arranged between each porous plate 2 and the filling plate 3, one end of the flexible connecting block 4 is hinged with a clamping plate 41, and the other end is connected to a handle 42, a clamping groove 411 is provided on the surface of the clamping plate 41, and the porous plate 2 is hinged with a rotating wheel 5 at one end near the handle 42;

[0024] A spring is provided in the clamping plate 41, and the user controls the filling plate 3 to be positioned by the clamping groove 411 on the surface of the clamping plate 41. The clamping groove 411 can lead one end of the filling plate 3 out through the clamping groove 411 while clamping the filling plate 3 normally, thereby avoiding damage to the filling plate 3. By applying tension to the handle 42, the flexible hook block 4 drives the filling plate 3 to move. With the assistance of the arc side of the rotating wheel 5, the filling plate 3 that has reached the end of its service life can be taken out for replacement with minimal damage to the filling plate 3, thereby avoiding the generation of waste and debris, and at the same time avoiding damage to the remaining sound insulation materials that are still intact, thereby reducing the cost of replacing the filling plate 3.

[0025] like Figure 6 As shown, the porous plate 2 is provided with a plurality of loop through holes 21 on a side away from the filling plate 3, and the inner wall of the loop through hole 21 is connected with a plurality of secondary through holes 22. Both ends of the loop through hole 21 and the secondary through hole 22 are provided on the side of the porous plate 2 away from the filling plate 3. The loop through hole 21 and the secondary through hole 22 are in the shape of an arc. At the same time, the porous plate 2 is provided with a plurality of staggered staggered plates 6 on a side away from the filling plate 3.

[0026] The loop through holes 21 and secondary through holes 22 provided in the porous plate 2 provide channels for sound flow by imitating the through holes of sponge, which can reduce noise while improving the life of the sound insulation device and reducing the cost of subsequent replacement of the interior of the barrier. At the same time, the porous plate 2 can also better cooperate with the offset plate 6 to achieve the effect of sound insulation and noise reduction.

[0027] A pair of matching blocks 7 are arranged between the two end frames 1. The matching blocks 7 are symmetrically arranged at both ends of the filling block. The side surfaces of each matching block 7 are fitted with the offset plate 6. The matching blocks 7 can match with the offset plate 6 to avoid the porous plate 2 and the filling plate 3 being exposed to the outside. At the same time, they can shape the sound bridge formed in the area between the two filling plates 3, which can effectively isolate the noise and effectively enhance the noise reduction effect of the barrier.

[0028] First, in daily use, the noise will be effectively reduced after passing through the staggered arrangement of the offset plates 6, the guidance of the loop through holes 21 and the secondary through holes 22 in the porous plate 2, and the gaps in the material itself and the hollow sound bridge in the filling layer, thereby controlling the noise propagation on both sides of the noise reduction barrier;

[0029] After a long period of use, the material in the filling layer undergoes natural aging and the sound insulation effect gradually weakens. In order to maintain the spatial privacy on both sides of the noise reduction barrier, the fitting block 7 is removed and the filling panel 3 is introduced into the clamping groove 411 on the surface of the splint 41. Then, by pulling the handle 42 at the other end of the flexible hooking block 4, the filling panel 3 is controlled to move with the flexible hooking block 4. At the same time, the flexible hooking block 4 will contact the rotating wheel 5, and the filling panel 3 will be led out through the arc-shaped outer surface of the rotating wheel 5, thereby avoiding damage to the aged filling panel 3 during transportation, which will lead to the failure of removing the filling panel 3. After the aged filling layer is removed, the splint 41 is connected with a new filling panel 3, thereby filling the vacant position of the original aged filling layer.

[0030] The above describes the implementation mode of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation mode. For ordinary technicians in this technical field, after knowing the contents recorded in the present invention, they can make several equivalent changes and substitutions without departing from the principles of the present invention. These equivalent changes and substitutions should also be regarded as belonging to the scope of protection of the present invention.
