[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 、 Figure 3 shown, a noise barrier device includes: a front support frame 1, the bottom of the front support frame 1 is provided on the ground; a rear support frame 2, the top of the rear support frame 2 is rotatably connected to the front support frame 1, and a first sound insulation board 3 is detachably connected to the rear support frame 2; a folding sound blocking mechanism 4, the folding sound blocking mechanism 4 is slidably connected to the front support frame 1; a compensation sound insulation board 5, the compensation sound insulation board 5 is rotatably connected to the bottom of the rear support frame 2; a leg assembly 6, the leg assembly 6 is provided on the rear wall of the rear support frame 2, and the leg assembly 6 supports the ground.

[0024] The bottom of the front support frame 1 is anchored to the ground to fix the position of the front support frame 1. Each side wall of the front support frame 1 is provided with two card slots 11, and a second sound insulation board 12 can be inserted into the card slots 11. The top of the second sound insulation board 12 is higher than the top surface of the front support frame 1. Since the top surface of the front support frame 1 is provided with a rotating connection component with the rear support frame 2, which will cause a reduction in the sound blocking height, the second sound insulation board 12 is set higher than the front support frame, so that the sound blocking height meets the requirements. If a higher sound blocking height is required, the second sound insulation board 12 with the corresponding height can be replaced.

[0025] The top end of the rear support frame 2 is provided with a connecting shaft 21, the connecting shaft 21 is rotatably connected to the top end of the front support frame 1, and the height of the rear support frame 2 is less than the height of the front support frame 1. When the device is in the storage state, the rear support frame 2 is in a vertical state, reducing the floor area and facilitating transportation.

[0026] A slot penetrates through the side wall of the rear support frame 2, and the first sound insulation board 3 is arranged in the slot. When performing two-way sound insulation, the first sound insulation board 3 is inserted into the rear support frame 2. At this time, a sound insulation space is formed between the first sound insulation board 3 and the second sound insulation board 12. When multiple such devices are continuously installed, operations with relatively high noise in the sound insulation space can effectively reduce the noise impact on the outside. Installing the first sound insulation board 3 adds an additional barrier to sound blocking, resulting in a better sound insulation effect.

[0027] As Figure 2As shown, the folding sound-blocking mechanism 4 includes a folding plate 41, a slider 42, and a slideway 43. The slideway 43 is provided on the side wall of the front support frame 1, and the slider 42 is provided at the bottom of the folding plate 41. The slider 42 is slidably connected to the slideway 43. The folding plate 41 is made of a flexible sound-insulating material, such as sound-insulating sponge. By pulling the slider 42 to move along the slideway 43, the folding plate 41 can be folded and unfolded. When the slider 42 is located at the bottom end of the slideway 43, the folding plate 41 is corrugated, which can increase the area for filtering sound and enhance the sound-blocking effect.

[0028] When the device is not in use, the slider 42 can be slid upward to store the folding plate 41 into a rectangular block, reducing the possibility of damage to the rectangular plate. A first positioning hole 15 is provided at the upper end of the side wall of the front support frame 1, and a second positioning hole is provided at the bottom of the folding plate 41. When the slider 42 moves upward, the first positioning hole 15 and the second positioning hole overlap. At this time, a positioning pin 16 can be inserted into the first positioning hole 15 and the second positioning hole. After inserting the positioning pin 16, the movement of the slider 42 is restricted, thereby maintaining the storage state of the folding plate 41.

[0029] A connection groove 13 is provided on the rear wall of the front support frame 1. A vibration plate is detachably connected in the connection groove 13, and a vibration motor 14 is provided on the vibration plate. Since the folding plate 41 cannot be separated from the front support frame 1, it is inconvenient to clean the dust on the folding plate 41. When dust needs to be cleaned, the folding plate 41 is unfolded, and then the vibration motor 14 is installed in the connection groove 13. The vibration motor 14 is started to drive the folding plate 41 to vibrate, and the dust on the folding plate 41 is shaken off to achieve the purpose of cleaning.

[0030] When the rear support frame 2 rotates, there is a gap between the rear support frame 2 and the ground. The compensation sound-blocking plate 5 is used to block this gap to form a complete sound-blocking barrier, achieving the effect of sound isolation. A buckle 51 is provided on the side wall of the compensation sound-blocking plate 5, and a connecting plate 22 is provided at the front end of the rear support frame 2. A card hole 23 is provided on the connecting plate 22. The buckle 51 can be inserted into the card hole 23. In the storage state, the compensation sound-blocking plate 5 fits with the rear support frame 2, and the buckle 51 is in the card hole 23. After the rear support frame 2 is unfolded, the compensation sound-blocking plate 5 is rotated downward so that the bottom of the compensation sound-blocking plate 5 contacts the ground. Rubber wheels 52 are provided at the bottom of the compensation sound-blocking plate 5, and the rubber wheels 52 roll on the ground. Thus, the compensation sound-blocking plate 5 and the first sound-insulating plate 3 cooperate to complete sound isolation.

[0031] The outrigger assembly 6 fixes the position of the rear support frame. The outrigger assembly 6 includes a fixed rod 61, a telescopic rod 62 and a support 63. The top of the fixed rod 61 is rotatably connected to the rear support frame 2. The telescopic rod 62 is slidably connected to the inner cavity of the fixed rod 61. The support 63 is rotatably connected to the bottom of the telescopic rod 62. After fixing the angle of the rear support frame 2, the telescopic rod 62 is allowed to freely extend, so that the support 63 contacts the ground. A positioning nut 64 penetrates through the side wall of the fixed rod 61. At this time, the positioning nut 64 is tightened so that the positioning nut 64 abuts against the telescopic rod 62 to limit the movement of the telescopic rod 62. The friction between the support 63 and the ground restricts the rotation of the rear support frame 2.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
