Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a ventilation device installed inside a curtain wall. Background Technology

[0002] As a common exterior envelope structure in modern buildings, building curtain walls sometimes require integrated ventilation systems to facilitate indoor-outdoor air exchange. In such applications, the mounting frame used to support and secure the ventilation ducts is a crucial component.

[0003] However, existing curtain wall installation frames mostly use rigidly connected fixed brackets by welding or bolts, which have obvious drawbacks: their support angles are fixed, making them unable to adapt to complex curtain wall structures; the support height is inconvenient to adjust, or can only be adjusted in a limited and rough manner; at the same time, the spacing between two support points cannot be changed once it is fixed, making it difficult to flexibly adapt to the installation requirements of pipes with different spacing. Therefore, when dealing with complex installation environments or ventilation ducts of different specifications, existing technologies are cumbersome to install, have poor adaptability, and are difficult to adjust flexibly and precisely, limiting their versatility and efficiency. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail below.

[0020] This application provides a ventilation device installed inside a curtain wall, employing the following technical solution: Reference Figure 1 The ventilation system mainly comprises two symmetrically arranged support units 1. Each support unit 1 includes a fixing collar 11, a support vertical rod 12, and a hollow horizontal tube 13 connected in sequence to form an L-shaped support rod. The fixing collar 11 is typically fixedly installed with embedded parts within the curtain wall, forming a stable support connection foundation. The bottom end of the fixing collar 11 is rotatably connected to the top end of the support vertical rod 12 via an angle adjustment mechanism 2. The angle adjustment mechanism 2 is used to adjust the angle between the fixing collar 11 and the support vertical rod 12, thereby adapting to different installation angle requirements. The hollow horizontal tube 13 is arranged laterally at the bottom end of the support vertical rod 12. The hollow horizontal tubes 13 of the two support units 1 are connected by a widening mechanism 3. The widening mechanism 3 is used to adjust the spacing between the two hollow horizontal tubes 13 to accommodate ventilation ducts of different widths. The two symmetrical support units 1 enable the overall ventilation system to stably support the ventilation ducts, and the angle adjustment mechanism 2 and the widening mechanism 3 allow for multi-dimensional adjustments, effectively improving the adaptability and installation accuracy of the system.

[0021] Reference Figure 1 , Figure 2 and Figure 3The angle adjustment mechanism 2 includes a U-shaped plate 21, a support plate 22, and an angle adjusting bolt 23. The top surface of the U-shaped plate 21 is fixedly connected to the bottom of the fixing collar 11, and the two sides of the U-shaped plate 21 extend downwards. Two support plates 22 are configured, located on the outer sides of the two sides of the U-shaped plate 21 respectively. The upper end of the support plate 22 is attached to the outer wall of the U-shaped plate 21. The angle adjusting bolt 23 is inserted and installed in the middle of the two sides of the U-shaped plate 21. The support plate 22 and the U-shaped plate 21 can be securely connected by matching the angle adjusting bolt 23 with the nut. The lower end of the support plate 22 is fixed to the outer wall of the support vertical rod 12 by bolts. By rotating the nuts on both sides of the angle adjusting bolt 23, the support plate 22 can rotate relative to the U-shaped plate 21, thereby driving the support vertical rod 12 to rotate relative to the fixing collar 11, adjusting the included angle between the fixing collar 11 and the support vertical rod 12. After adjusting to the included angle required for construction and installation, tightening the nuts on both sides of the angle adjusting bolt 23 will fix the position. The above structure allows users to flexibly adjust the angle of the ventilation duct during installation, ensuring a match with the curtain wall structure, improving the adaptability and precision of the installation, while also being simple in structure and easy to operate.

[0022] Furthermore, referring to Figure 1 , Figure 2 and Figure 3 Multiple positioning slots 121 are spaced apart along the length of the side wall of the supporting vertical rod 12. A connecting piece 131 is fixedly connected to the end of the hollow horizontal tube 13, and a fastening bolt 132 is inserted through the connecting piece 131. The fastening bolt 132 can selectively align with any positioning slot 121 and be locked with a nut, fixing the hollow horizontal tube 13 to different height positions of the supporting vertical rod 12. Users can flexibly select different positioning slots 121 according to the installation height requirements of the ventilation duct and quickly fix them using the fastening bolt 132, achieving multi-level height adjustment and enhancing the versatility and installation flexibility of the device.

[0023] Reference Figure 4 and Figure 5The widening mechanism 3 includes an extension column 31, a rack 32, a mounting box 33, a central column 34, and a gear 35. The two ends of the extension column 31 slide through the interiors of the hollow horizontal tubes 13 on both sides. The rack 32 is bonded or welded to the side wall of the extension column 31. Furthermore, both ends of the rack 32 along its length are integrally formed with limiting plates 321. The limiting plates 321 extend outward perpendicular to the side wall of the extension column 31, and abut against the limiting protrusions (not shown in the figure) on the inner wall of the hollow horizontal tube 13. This limits the sliding stroke of the extension column 31 within the hollow horizontal tube 13, preventing the extension column 31 from detaching from the hollow horizontal tube 13 due to excessive sliding, thus ensuring operational safety and reliability. Mounting box 33 is fixedly connected to the outer wall of one of the hollow horizontal tubes 13. A central column 34 is vertically inserted into the mounting box 33 and can rotate. The upper end of the central column 34 is located inside the mounting box 33, and the lower end extends downwards through the bottom of the mounting box 33. Vertically spaced grooves 341 are formed on the outer wall of the extended portion of the central column 34. A gear 35 is fixedly connected to the top surface of the central column 34. The circumference of the gear 35 protrudes from the side wall of the mounting box 33 and meshes with a rack 32. When the central column 34 is rotated, the gear 35 rotates accordingly, driving the rack 32 to move and causing the expansion column 31 to slide inside the hollow horizontal tube 13, thereby expanding or contracting the distance between the two support units 1. The gear 35 and rack 32 transmission method provides smooth and precise adjustment, allowing the device to adapt to ventilation ducts of different widths and improving its versatility.

[0024] Furthermore, referring to Figure 5 and Figure 6 The widening mechanism 3 also includes a limiting block 36 and a threaded rod 37. The main body of the limiting block 36 is circular, and a lug 361 extends laterally from the outer wall of the circle. The circumference of the limiting block 36 surrounds the periphery of the central column 34, and the inner wall is provided with locking teeth that match the groove 341 on the outer wall of the central column 34. The threaded rod 37 is threaded through the lug 361 extending laterally from the limiting block 36 in a direction perpendicular to the central column 34. Rotating the threaded rod 37 can drive the limiting block 36 to engage or disengage from the central column 34, thereby locking or releasing the central column 34. When the spacing is adjusted to the correct position, tightening the threaded rod 37 engages the limiting block 36 with the central column 34, preventing the central column 34 from rotating accidentally, thus fixing the length of the widening mechanism 3 and ensuring the stability and safety of the support.

[0025] Furthermore, referring to Figure 6 A wheel 371 is fixedly connected to the outer end of the threaded rod 37. A handle 372 extends integrally from the side wall of the wheel 371 and is perpendicular to the wheel 371. The wheel 371 facilitates manual operation of the threaded rod 37 by the user, and the handle 372 increases the point of force, making it easier to operate the wheel 371 and improving the convenience and efficiency of operation.

[0026] The application process and implementation principle of this application embodiment are as follows: In the actual installation process, firstly, two support units 1 are symmetrically placed inside the curtain wall structure, and the ventilation duct is placed within the support area enclosed by the two support units 1. Then, according to the installation angle requirements of the duct, the angle between the fixing collar 11 and the support vertical rod 12 is adjusted by the angle adjustment mechanism 2: loosen the angle adjustment bolt 23, rotate the support plate 22 to the target angle, and then tighten the angle adjustment bolt 23 to fix it. Next, according to the height requirements of the duct, select a suitable positioning groove 121 on the support vertical rod 12, and fix the hollow horizontal tube 13 to the support vertical rod 12 with bolts. Finally, according to the width requirements of the duct, the distance between the two hollow horizontal tubes 13 is adjusted by the widening mechanism 3: rotate the central column 34, the gear 35 drives the rack 32 and the expansion column 31 to slide until the distance is appropriate; then rotate the threaded rod 37 to make the limiting block 36 clamp the central column 34 and lock the position. The entire device achieves flexible and precise support for ventilation ducts through multi-dimensional adjustment, effectively adapting to complex curtain wall installation environments, improving installation efficiency and quality, while reducing installation difficulty and cost.

[0027] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
