However, there are some problems in the actual use of traditional building ventilation ducts. During the ventilation process, due to the flow of air in the ducts and the operation of equipment such as fans, relatively large noises will be generated. These noises will not only affect the quietness of the indoor environment and bring interference to people's life and work, but also general ventilation ducts usually use simple metal or plastic materials, and the sound insulation effect of these materials is limited and cannot meet the actual needs. Therefore, a building ventilation duct with a sound insulation structure is proposed to solve the above problems. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-5, an embodiment provided by the present utility model: a building ventilation duct with a sound insulation structure, including a ventilation duct body 1, an installation frame 2 is fixedly installed on the front side of the ventilation duct body 1, a sound insulation cotton 3 is arranged inside the ventilation duct body 1, the surface of the sound insulation cotton 3 is in contact with the inner wall of the ventilation duct body 1, a limiting component 4 for limiting the sound insulation cotton 3 is arranged on the back side of the ventilation duct body 1, and an installation component 5 for installing the ventilation duct body 1 is arranged on the top of the ventilation duct body 1. First, the ventilation duct body 1 can be installed at the position where ventilation is required. At this time, the bottom of the installation frame 2 will be fixed to the ventilation place, and then the ventilation duct body 1 can be fixed through the installation component 5. At this time, the sound insulation cotton 3 can be placed inside the ventilation duct body 1. When the sound insulation cotton 3 is in full contact with the ventilation duct body 1, the sound insulation cotton 3 can be limited through the limiting component 4. At this time, when noise appears inside the ventilation duct body 1, the noise will be absorbed by the sound insulation cotton 3, thus achieving the advantage of sound insulation of the ventilation duct body 1.

[0031] Refer to Figures 1-5 , the limiting component 4 includes a fan 41, an installation frame 42 is fixedly installed on the surface of the fan 41, the installation frame 42 is located inside the ventilation duct body 1, several groups of limiting blocks 43 are fixedly installed on the front side of the installation frame 42, and the outer side of the limiting blocks 43 is in contact with the inner side of the sound insulation cotton 3. Through the mutual cooperation of the fan 41, the installation frame 42 and the limiting blocks 43, first, the installation frame 42 can be pushed forward. The movement of the installation frame 42 drives the limiting blocks 43 and the fan 41 to move forward. When the installation frame 42 completely enters the ventilation duct body 1, at this time, the outer side of the limiting blocks 43 will also be in contact with the inner side of the sound insulation cotton 3, and at this time, the sound insulation cotton 3 can be limited. Subsequently, the fan 41 can be started for ventilation work. Under the action of the sound insulation cotton 3, the noise generated by the fan 41 can be effectively absorbed. Rotating plates 44 are rotatably installed at the top and bottom of the back side of the ventilation duct body 1. Connecting blocks 45 are fixedly installed at the top and bottom of the back side of the ventilation duct body 1. A bolt 46 is arranged on the left side of the connecting block 45, and the right end of the bolt 46 penetrates into the rotating plate 44, and the bolt 46 is threadedly installed with the rotating plate 44. Through the mutual cooperation of the rotating plate 44, the connecting block 45 and the bolt 46, when the installation frame 42 completely enters the ventilation duct body 1, the rotating plate 44 can be rotated at this time. When the rotating plate 44 rotates to a horizontal state, the bolt 46 can be rotated at this time. The rotation of the bolt 46 will enter the rotating plate 44, so as to limit the rotating plate 44 and prevent the rotating plate 44 from shaking when limiting the installation frame 42. Blocks 6 are fixedly installed at the top and bottom of the back side of the ventilation duct body 1, and the outer side of the blocks 6 is in contact with the inner side of the rotating plate 44. Through the arrangement of the blocks 6, the rotating plate 44 can be limited to prevent the rotating plate 44 from rotating too much, resulting in the rotating plate 44 being unable to effectively limit the installation frame 42.

[0032] Reference Figures 1-5 As shown in Figures 1-5 , the installation component 5 includes two sets of screw sleeves 51. The bottom of the screw sleeve 51 is fixedly installed on the top of the ventilation duct body 1. A screw rod 52 is installed inside the screw sleeve 51 in a threaded manner. The top of the screw rod 52 is fixedly installed with an installation block 53. Through the mutual cooperation of the screw sleeve 51, the screw rod 52 and the installation block 53, when the ventilation duct body 1 is installed at a high place, the screw rod 52 can be rotated at this time. When the screw rod 52 rotates, it will gradually disengage from the screw sleeve 51. The rotation of the screw rod 52 will also drive the installation block 53 upward. When the top of the installation block 53 contacts the ceiling, the installation block 53 can be fixed by expansion screws at this time, thus achieving the advantage of installing the ventilation duct body 1. A filter screen 7 is fixedly installed on the back of the installation frame 42. The filter screen 7 is located on the back of the fan 41. Through the setting of the filter screen 7, the air entering the ventilation duct body 1 can be filtered to prevent impurities in the air from entering the ventilation duct body 1 and causing damage to the fan 41 and making it unable to continue to be used. A clamping block 8 is fixedly installed on the front side inside the ventilation duct body 1. The sound insulation cotton 3 is located inside the clamping block 8. Through the setting of the clamping block 8, the sound insulation cotton 3 can be limited, preventing the fan 41 from generating a large amount of wind during operation, which may cause the sound insulation cotton 3 to shake, resulting in poor sound insulation effect of the sound insulation cotton 3.

[0033] Working principle: First, the ventilation duct body 1 can be installed at the position where ventilation is required. At this time, the bottom of the installation frame 2 will be fixed to the ventilation area. Then, the screw rod 52 can be rotated. When the screw rod 52 rotates, it will gradually disengage from the screw sleeve 51. The rotation of the screw rod 52 will also drive the installation block 53 upward. When the top of the installation block 53 contacts the ceiling, the installation block 53 can be fixed by expansion screws at this time. Then, the sound insulation cotton 3 can be placed inside the ventilation duct body 1. When the entire front side of the sound insulation cotton 3 enters the clamping block 8, the installation frame 42 can be pushed forward at this time. The movement of the installation frame 42 drives the limiting block 43 and the fan 41 to move forward. When the entire installation frame 42 enters the ventilation duct body 1, the outside of the limiting block 43 will also contact the inside of the sound insulation cotton 3 at this time, and the sound insulation cotton 3 can be limited at this time. Then, the rotating plate 44 can be rotated. When the rotating plate 44 rotates to a horizontal state, the bolt 46 can be rotated at this time. The rotation of the bolt 46 will enter the rotating plate 44, thereby limiting the rotating plate 44. Finally, the fan 41 can be started for ventilation work. At this time, the noise generated by the fan 41 will be absorbed by the sound insulation cotton 3, thus achieving the advantage of sound insulation of the ventilation duct body 1.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model 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 on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
