[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a soundproof cabin with an arc-shaped cover, comprising an arc-shaped aluminum profile 1 and an arc-shaped cover 2, wherein the arc-shaped aluminum profile 1 is provided with arc-shaped covers 2 at both ends.

[0025] The curved aluminum profile 1 serves as the main supporting structural frame material for the soundproof cabin, exhibiting good strength and stability. Curved covers 2 are installed at both ends of the curved aluminum profile 1, forming a closed top and bottom structure for the soundproof cabin. The curved design not only enhances the aesthetics but also improves the mechanical properties of the structure to a certain extent, while providing a relatively independent interior space and reducing the intrusion of external noise.

[0026] Crossbars 3 and uprights 4 are provided between the curved aluminum profiles 1. The curved aluminum profiles 1, crossbars 3, and uprights 4 form a rectangular frame. The crossbars 3 and uprights 4, together with the curved aluminum profiles 1, form a rectangular frame, further enhancing the stability and robustness of the overall structure of the soundproof cabin. This frame structure can evenly distribute the force, making the soundproof cabin less prone to deformation when subjected to certain external forces, and providing a stable installation foundation for internal sound insulation panels and other components.

[0027] A sealed door 5 is provided on one side of the rectangular frame. The sealed door 5 facilitates personnel to enter and exit the soundproof cabin. At the same time, its sealing design can effectively prevent external noise from entering the cabin through the door gap, ensuring a quiet environment inside the soundproof cabin and improving the sound insulation effect.

[0028] The rectangular frame has horizontal sound insulation panels 7 at the top and bottom, vertical sound insulation panels 6 on both sides, and a ventilation fan 8 at the center of the top. The horizontal and vertical sound insulation panels 7 and 6 are respectively installed at the top, bottom, and sides of the rectangular frame, forming a comprehensive sound barrier. They absorb and reflect sound waves from the outside, reducing noise transmission and creating a low-noise working or resting environment inside the soundproof cabin. The ventilation fan 8, installed at the center of the top of the rectangular frame, allows for air exchange between the inside and outside of the cabin while maintaining sound insulation. It expels stale air and introduces fresh air, keeping the cabin air fresh, improving user comfort, and preventing discomfort caused by prolonged exposure to a confined space.

[0029] The curved aluminum profile 1 has slots at both ends for engaging the horizontal sound insulation panels 7 and the vertical sound insulation panels 6. The curved aluminum profile 1 also contains several cavities. The slot design allows the horizontal and vertical sound insulation panels 7 and 6 to be easily and securely installed on the curved aluminum profile 1, simplifying the installation process and improving efficiency. Simultaneously, the slot connection ensures a tight fit between the sound insulation panels and the aluminum profile, reducing gaps and further improving sound insulation. The cavities inside the curved aluminum profile 1 serve a dual purpose of heat insulation and sound insulation. The cavities prevent heat transfer, reducing the impact of external temperature on the cabin interior and contributing to energy conservation to some extent. Furthermore, the cavities reflect and absorb sound waves, enhancing the sound insulation performance of the aluminum profile itself and further improving the overall sound insulation effect of the soundproof cabin.

[0030] The inner walls at both ends of the curved aluminum profile 1 are provided with first end positioning grooves 101, and the inner walls at both ends of the curved aluminum profile 1 are provided with second end positioning grooves 102 above the first end positioning grooves 101. The inner walls at the curved corners of the curved aluminum profile 1 are provided with fan-shaped positioning grooves 103. These positioning grooves provide precise positioning for the installation of the curved cover 2, ensuring that the curved cover 2 can be accurately and securely installed on the curved aluminum profile 1. The positioning grooves of different positions and shapes cooperate with the corresponding positioning components on the curved cover 2 to restrict the movement of the curved cover 2 in multiple directions, enhance the firmness and stability of the connection, and ensure the integrity of the overall structure of the soundproof cabin.

[0031] A circumferential positioning plate 205 is provided on one side of the arc-shaped cover 2. The circumferential positioning plate 205 can be locked on the outer side of the end of the arc-shaped aluminum profile 1. The circumferential positioning plate 205 is locked on the outer side of the end of the arc-shaped aluminum profile 1, which further enhances the connection stability between the arc-shaped cover 2 and the arc-shaped aluminum profile 1, prevents the arc-shaped cover 2 from shifting in the horizontal direction, and ensures the airtightness of the soundproof cabin and the overall structural integrity.

[0032] The inner walls at both ends of the arc-shaped cover 2 are provided with end positioning strips 201. Above the end positioning strips 201, end positioning plates 202 are provided on the inner walls at both ends of the arc-shaped cover 2. An arc-shaped positioning plate 203 is provided on the inner wall of the arc-shaped corner of the arc-shaped cover 2, and an oblique positioning plate 204 is provided on one side of the inner side of the arc-shaped corner of the arc-shaped cover 2. These positioning components cooperate with the corresponding positioning grooves on the arc-shaped aluminum profile 1 to position and fix the arc-shaped cover 2 from multiple directions. The end positioning strips 201, end positioning plates 202, arc-shaped positioning plates 203, and oblique positioning plates 204 are tightly fitted with their corresponding positioning grooves, ensuring that the arc-shaped cover 2 will not shake or shift after installation, improving the accuracy and stability of the connection, and guaranteeing the overall performance of the soundproof cabin.

[0033] The outer contour of the end positioning strip 201 fits against the inner wall of the first end positioning groove 101, the outer contour of the end positioning strip 201 fits against the inner wall of the second end positioning groove 102, the arc-shaped positioning plate 203 fits against the arc-shaped inner wall of the fan-shaped positioning groove 103, and the inclined positioning plate 204 fits against the inclined inner wall of the fan-shaped positioning groove 103. This tight fit design minimizes the gap between the arc-shaped cover 2 and the arc-shaped aluminum profile 1, preventing noise from entering the cabin through the gap and further improving the sound insulation effect of the soundproof cabin. At the same time, the precise fit also ensures uniform stress among the components and enhances the reliability of the connection.

[0034] There are multiple vertical soundproof panels 6. Each adjacent vertical soundproof panel 6 has a rectangular strip 602 on one side and a rectangular groove 601 on the other side that mates with the rectangular strip 602. Multiple vertical soundproof panels 6 are spliced ​​together using the rectangular strip 602 and the rectangular groove 601. This connection method is simple and convenient, allowing for flexible adjustment of the number and length of the vertical soundproof panels 6 according to actual needs. Simultaneously, the tight fit between the rectangular strip 602 and the rectangular groove 601 ensures a tight connection between adjacent soundproof panels, reduces gaps, prevents noise from entering the cabin through the splicing points, and improves the overall sound insulation effect.

[0035] A rectangular strip 602 is also provided on one side of the adjacent horizontal sound insulation panel 7, and a rectangular groove 601 that cooperates with the rectangular strip 602 is also provided on the other side of the horizontal sound insulation panel 7. Similar to the vertical sound insulation panel 6, the horizontal sound insulation panel 7 also adopts the splicing method of rectangular strip 602 and rectangular groove 601, which facilitates installation and adjustment, ensures the tightness of the connection between the horizontal sound insulation panels 7, and further enhances the sound insulation performance of the top and bottom of the soundproof cabin.

[0036] The outer contour dimension of the arc-shaped cover 2 is larger than the cross-sectional outer wall dimension of the arc-shaped aluminum profile 1. This design allows the arc-shaped cover 2 to completely cover the end of the arc-shaped aluminum profile 1, forming a better sealing effect and preventing noise from entering the cabin through the end gaps. At the same time, the larger outer contour dimension also increases the structural strength of the arc-shaped cover 2 and improves its resistance to deformation.

[0037] In terms of sound insulation, the curved-cover soundproof cabin of this application utilizes the cavity structure of the curved aluminum profile 1, the precise positioning groove design, and the tight splicing between the sound insulation panels to comprehensively prevent the intrusion of external noise, creating a quiet environment inside. Regarding structural stability, the rectangular frame, composed of the curved aluminum profile 1, crossbars 3, and uprights 4, along with various positioning components of the curved cover 2, makes the entire soundproof cabin structure robust and resistant to deformation.

[0038] The curved aluminum profile 1 and curved cover 2, through precise positioning groove and positioning plate design, improve the connection accuracy and stability between components, and reduce noise caused by component loosening; the sound insulation board is installed by splicing rectangular strips and rectangular grooves, making installation more convenient and flexible, and ensuring the tightness of the splice, thus improving the sound insulation effect; the curved design and cavity structure not only enhance the structural strength, but also further improve the sound insulation and heat insulation performance, providing users with a better user experience.

[0039] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
