DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical solution: a noise protection device that is convenient for noise reduction, comprising: a support block 1, a noise reduction plate 2 is installed on the top of the support block 1;

[0026] One side of the noise reduction plate 2 is connected to a refraction plate 3 through a rotating shaft, the end of the refraction plate 3 close to the noise reduction plate 2 is connected to a connecting rod 4 through a rotating shaft, the end of the connecting rod 4 away from the refraction plate 3 is connected to a screw sleeve 5 through a rotating shaft, the middle of the screw sleeve 5 is connected to a screw 6 that passes through the noise reduction plate 2, a sound-absorbing hole 7 is opened on one side of the noise reduction plate 2, a first sound-absorbing sponge layer 8 is installed on the inner wall of the noise reduction plate 2, a cavity 9 is provided on one side of the first sound-absorbing sponge layer 8, and a second sound-absorbing sponge layer 10 is provided on the side of the cavity 9 away from the first sound-absorbing sponge layer 8, and the refraction plate 3 forms a rotating structure with the noise reduction plate 2 through the rotating shaft.

[0027] When the cam 5 is in the air, the cam 5 is in the air, and the cam 5 is in the air, and the cam 5 is in the air, and the cam 5 is in the air, and the cam 5 is in the air, and the cam 5 is in the air, and the cam 5 is in the air, and the cam 5 is in the air. Refracted, since the refraction plate 3 is in an inclined state, it can refract noise at different angles. The noise will lose some energy in the process of refraction, which can play a role in noise reduction. Some noise will enter the interior of the noise reduction plate 2 through the sound-absorbing holes 7. The interior of the noise reduction plate 2 is provided with a first sound-absorbing sponge layer 8 and a second sound-absorbing sponge layer 10. When the noise passes through the first sound-absorbing sponge layer 8, it will be absorbed by the first sound-absorbing sponge layer 8. A small part of the noise will enter the cavity 9. Since the cavity 9 is wrapped in the first sound-absorbing sponge layer 8 and the second sound-absorbing sponge layer 10, the internal noise cannot be transmitted and can only enter the second sound-absorbing sponge layer 10 or return to the first sound-absorbing sponge layer 8, so that the noise can be better absorbed. In addition, the material of the entire noise reduction plate 2 is polyester fiber sound-absorbing board, which also has a good noise reduction effect, thereby making the noise reduction effect of the entire noise protection device better, and facilitating noise reduction processing.

[0028] See Figure 1 、 Figure 2 、 Figure 4 and Figure 6 It can be seen that when in use, the screw 6 can be rotated according to the noise reduction requirements. The rotation of the screw 6 will drive the connecting rod 4 to rotate through the screw sleeve 5, and with the cooperation of the connecting rod 4 and the rotating shaft, the refraction plate 3 will rotate. By changing the angle of the refraction plate 3, noise at different angles can be refracted, and the noise can be absorbed by the first sound-absorbing sponge layer 8 and the second sound-absorbing sponge layer 10 inside the noise reduction plate 2, so that the noise reduction effect of the entire noise reduction plate 2 is better, which is convenient for noise reduction processing.

[0029] The side of the noise reduction plate 2 is connected with the connecting block 11, the connecting block 11 and the noise reduction plate 2 are connected with the rotating shaft 12, the outer side of the rotating shaft 12 and the groove of the noise reduction plate 2 are provided with the gear 13, one side of the gear 13 is provided with the clamping block 14, the top of the clamping block 14 is connected with the top rod 15 penetrating through the noise reduction plate 2, one side of the top rod 15 is provided with the top block 16 through the slope, the end of the top block 16 is sleeved with the fixed block 17, the groove of the top block 16 and the fixed block 17 is installed with the movable spring 18, one end of the connecting block 11 away from the noise reduction plate 2 is connected with another group of noise reduction plates 2 through the rotating shaft 12.

[0030] In specific implementation, when the angle of the two groups of noise reduction plates 2 needs to be adjusted, the top block 16 can be pulled into the fixed block 17, so that the top block 16 does not extrude the top rod 15 on one side through the slope, then the top rod 15 can be pulled upwards, so that the top rod 15 moves out of the groove of the noise reduction plate 2, the upward movement of the top rod 15 drives the clamping block 14 connected on one side to move upwards, at this time, the clamping block 14 is separated from the gear 13 on the outer side of the rotating shaft 12, without the limitation of the clamping block 14 on the gear 13, the rotating shaft 12 can be rotated, the connecting block 11 drives the noise reduction plate 2 connected on the other side to rotate, so that the angle of the noise reduction plate 2 can be quickly adjusted by the user, meeting the different use requirements of the user.

[0031] When the angle of the noise reduction plate 2 needs to be fixed, the top rod 15 can be extruded into the noise reduction plate 2, since one side of the top rod 15 close to the top block 16 and one side of the top block 16 are both inclined surface structures, at this time, the movement of the top rod 15 extrudes the top block 16 through the slope, after the top block 16 is extruded, it is retracted into the groove of the fixed block 17 and extrudes the movable spring 18 in the groove of the fixed block 17, at the same time, the top rod 15 continues to move downwards and drives the clamping block 14 on one side to move downwards, the downward movement of the clamping block 14 moves to one side of the gear 13, at this time, the clamping block 14 limits the gear 13, so that the gear 13 cannot rotate, the gear 13 cannot rotate, so that the rotating shaft 12 cannot rotate, so that the angle of the noise reduction plate 2 can be limited and fixed, at the same time, when the height of the inclined surface on one side of the top rod 15 is lower than the height of the top block 16, the top block 16 is not extruded by the top rod 15, the top block 16 is reset by the movable spring 18 and moves to one side of the top rod 15, at this time, the top block 16 can limit the top rod 15, so that the clamping block 14 on one side of the top rod 15 always limits the gear 13, ensuring that the noise reduction plate 2 cannot rotate through the rotating shaft 12.

[0032] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 It can be seen that when in use, the top block 16 can be pulled to one side according to the needs of use, and then the top rod 15 can be pulled upward. At this time, there is no limit on the gear 13 by the block 14, and the noise reduction plate 2 can be driven to rotate through the rotating shaft 12, so as to facilitate the adjustment of the angle of the noise reduction plate 2. At the same time, the two groups of noise reduction plates 2 can be rotated and folded through the rotating shaft 12 and the connecting block 11, so that the entire noise reduction plate 2 is easy to store and carry.

[0033] To sum up: when the noise protection device that is easy to reduce noise is used, it can be placed in a stable position by the support block 1 at the bottom of the noise reduction plate 2, and can be stably fixed to the ground by rotating the bolts according to the use requirements. When noise is generated in the surrounding area, when the noise is transmitted to the noise reduction plate 2, the noise can be reduced by the noise reduction plate 2 and the reduced sound is transmitted. This is the use feature of the noise protection device that is easy to reduce noise. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
