[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this specification, "multiple" refers to two or more.

[0023] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0024] Reference Figures 1-3 As shown, this embodiment of the utility model provides an exhaust duct for an underground parking garage, including a ventilation pipe 1, a connecting pipe 11 fixedly connected to the right end of the ventilation pipe 1, and an installation groove 12 formed on the left inner wall of the ventilation pipe 1, with the connecting pipe 11 embedded inside the installation groove 12 on the left side of the adjacent ventilation pipe 1; it also includes...

[0025] Fixing mechanism 2 is installed at both ends of the ventilation pipe 1 and is used to firmly fix two adjacent ventilation pipes 1 together.

[0026] The pulley mechanism 3 is located at the upper end of the ventilation pipe 1. The pulley mechanism 3 is used to connect two adjacent ventilation pipes 1 during installation. During operation, the pulley mechanism 3 aligns and pulls the connecting pipe 11 and the mounting groove 12 of the adjacent ventilation pipes 1 closer together, so that the connecting pipe 11 can move smoothly into the mounting groove 12. At the same time, the fixing mechanism 2 will fasten the two adjacent ventilation pipes 1, thereby realizing a quick and firm connection between the adjacent ventilation pipes 1, which greatly improves the installation efficiency and connection stability.

[0027] In a further embodiment, refer to Figure 3 The fixing mechanism 2 includes a first fixing block 21 and a second fixing block 22. A pair of first fixing blocks 21 are provided and fixedly connected to the front and rear ends of the left side of the outer wall of the ventilation pipe 1. A pair of second fixing blocks 22 are provided and fixedly connected to the front and rear ends of the right side of the outer wall of the ventilation pipe 1. The second fixing blocks 22 are fixedly connected to the first fixing blocks 21 at the left end of the adjacent ventilation pipe 1 by bolts 24. A connecting groove 211 is provided at the left end of the first fixing block 21. A first threaded hole 212 is provided at the end of the first fixing block 21 away from the ventilation pipe 1. A connecting block 221 is fixedly connected to the right end of the second fixing block 22. A through hole 222 is provided on the front end face of the connecting block 221. The connecting block 221 is located inside the connecting groove 211. The end of the bolt 24 passes through the threaded hole and the through hole 222 in sequence and is threadedly connected to the threaded hole. A suspension assembly 23 is also provided at the upper end of the connecting block 221. The suspension assembly 23 is used to fix the ventilation pipe 1 to the top plate of the underground garage.

[0028] In this embodiment, a fast, secure and precise connection between ventilation pipes 1 is achieved through a carefully designed fixing mechanism 2. The first fixing block 21 and the second fixing block 22 are respectively set at the front and rear ends of the ventilation pipe 1, forming a "mortise and tenon" type mating structure. When adjacent ventilation pipes 1 are connected, the connecting block 221 on the second fixing block 22 can be precisely embedded in the connecting groove 211 of the first fixing block 21. This nested structure not only improves the stability of the connection, but also effectively prevents the ventilation pipe 1 from shifting in the axial and radial directions. The bolt 24 passes through the first threaded hole 212 and the through hole 222 in sequence and is tightened, which further enhances the firmness of the connection and ensures that the ventilation pipe 1 will not loosen due to vibration or airflow impact during long-term operation.

[0029] In addition, the suspension assembly 23 allows the ventilation duct 1 to be firmly fixed to the ceiling of the underground garage via the threaded rod 231 and the positioning block 233. This not only provides reliable support for the ventilation duct 1, but also facilitates height adjustment and positioning during installation through the adjustable threaded connection, further improving the stability and reliability of the entire exhaust duct system. This design ensures installation efficiency while providing a strong guarantee for the long-term stable operation of the underground garage exhaust duct.

[0030] In a further embodiment, refer to Figure 3 The suspension assembly 23 includes a threaded rod 231 and a positioning block 233. The upper end face of the second fixing block 22 is provided with a second threaded hole 223. The threaded rod 231 is threadedly connected inside the second threaded hole 223. The positioning block 233 is rotatably connected to the upper end of the threaded rod 231. The upper end face of the positioning block 233 is provided with a positioning hole 234. The side wall of the threaded rod 231 is fixedly connected with a driving block 232.

[0031] In this embodiment, the ventilation pipe 1 is stably suspended and flexibly adjusted on the roof of the underground garage through the ingenious design of the suspension assembly 23. Specifically, the threaded rod 231 in the suspension assembly 23 is threadedly connected to the second threaded hole 223 at the upper end of the second fixing block 22. This threaded connection not only provides sufficient strength, but also allows the vertical position of the ventilation pipe 1 to be adjusted by rotating the threaded rod 231 to adapt to different installation height requirements. The positioning block 233 is rotatably connected to the upper end of the threaded rod 231, and the positioning hole 234 on its upper end face can be used to connect with the fixing device (such as expansion bolts or hooks) of the roof of the underground garage, thereby firmly suspending the ventilation pipe 1.

[0032] In addition, the drive block 232 on the side wall of the threaded rod 231 is designed to allow installers to manually rotate the threaded rod 231 to quickly adjust the suspension height of the ventilation pipe 1. The operation is simple and efficient. This suspension component 23 not only improves the flexibility and convenience of installing the ventilation pipe 1, but also ensures the stability of the ventilation pipe 1 after installation, effectively avoiding the impact on the normal operation of the ventilation system due to pipe shaking or displacement.

[0033] In a further embodiment, refer to Figure 2 The pulley mechanism 3 includes a first pulley 31 and a second pulley 32. Both the first pulley 31 and the second pulley 32 are rotatably connected to the upper left side of the ventilation pipe 1. The first pulley 31 is located to the left of the second pulley 32. The outer diameter of the first pulley 31 is smaller than the outer diameter of the second pulley 32. A third pulley 33 is rotatably connected to the upper right side of the ventilation pipe 1. The outer diameter of the third pulley 33 is the same as the outer diameter of the first pulley 31. A rope 34 is sleeved on the outer wall of the first pulley 31. The rope 34 passes around the side walls of the third pulley 33 and the second pulley 32 in sequence.

[0034] In this embodiment, the design of the pulley mechanism 3 cleverly utilizes the mechanical principle of the pulley block, significantly improving the ease of operation and efficiency during the installation of the ventilation pipe 1. Specifically, the combination of the first pulley 31, the second pulley 32, and the third pulley 33 forms a highly efficient pulley block structure. The outer diameters of the first pulley 31 and the third pulley 33 are relatively small, while the outer diameter of the second pulley 32 is relatively large. This combination of pulleys with different outer diameters can effectively prevent the rope 34 between the second pulley 32 and the third pulley 33 from contacting the first pulley 31.

[0035] When installing ventilation duct 1, by passing rope 34 sequentially around the first pulley 31, the third pulley 33, and the second pulley 32, the operator only needs to apply a small force to easily align and pull closer the connecting pipe 11 and sleeve of adjacent ventilation duct 1, achieving rapid connection. This not only reduces the labor intensity of the installers but also greatly shortens the installation time of ventilation duct 1. It is especially suitable for installation environments with limited space and large volume, such as underground garages. With the assistance of pulley mechanism 3, the installation of ventilation duct 1 becomes more efficient and convenient, while also improving the safety and reliability of the installation process.

[0036] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
