[0002] The widespread application of Building Information Modeling (BIM) technology has driven the development of HVAC system design towards digitalization and refinement. When traditional HVAC structures are designed in three dimensions based on BIM models, the model parameters need to be precisely matched with the physical installation during the construction phase.

[0003] Existing HVAC support structures mostly adopt fixed installation frames, whose bolt hole positions and bracket spacing are preset to serve a single model of equipment. When dealing with HVAC equipment of different sizes, it is necessary to add or remove shims or cut brackets to adapt them, which makes the disassembly and assembly process cumbersome and compromises the structural stability. In addition, when adjustments are needed during installation, it is necessary to repeatedly disassemble fasteners and calibrate the level, which is not only inefficient, but also prone to positioning failure due to stripped bolt threads, seriously affecting construction efficiency.

[0004] In view of this, a BIM-based HVAC structure is proposed. Utility Model Content

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0029] Please see Figure 1-8 .

[0030] This utility model is based on a BIM HVAC structure, including a mounting frame 1 and two support frames 3 movably mounted on the mounting frame 1 for mounting HVAC devices. The mounting frame 1 has multiple mounting holes 2 for fixing the mounting frame 1 to the wall. A mounting plate 7 is mounted on the mounting frame 1, and two movable blocks 17 are slidably mounted on the mounting plate 7. A first screw 15 and a second screw 16 are rotatably connected to the mounting plate 7 for driving the two movable blocks 17 to move relative to each other. A first limiting plate 18 is fixedly connected to the movable blocks 17, and a second limiting plate 18 is slidably connected to the movable blocks 17. The two limiting plates 19, the first limiting plate 18 and the second limiting plate 19 are used to limit the support frame 3. The adjustable spacing of the movable blocks 17 is to adapt to the installation requirements of different models of HVAC equipment. Because the spacing of the support frame 3 is often different when different models of HVAC equipment are installed, the adjustable spacing of the first limiting plate 18 and the second limiting plate 19 is to adapt to support frames 3 of different thicknesses. The adjustable spacing of the two movable blocks 17 and the adjustable spacing of the two limiting plates on the movable blocks 17 greatly improve the adaptability of the structure.

[0031] Furthermore, the threads of the first screw 15 and the second screw 16 are arranged in opposite directions. The first screw 15 and the second screw 16 are fixedly connected by a connecting rod 14. The first screw 15 and the second screw 16 are each connected to a first screw sleeve 25 by a ball screw pair thread. The two first screw sleeves 25 are fixedly connected to two movable blocks 17 respectively. That is to say, when the connecting rod 14 rotates, it can drive the movable blocks 17 on the first screw 15 and the second screw 16 to move closer or further apart. This arrangement makes it more convenient to adjust the spacing of the movable blocks 17.

[0032] It should be noted that when using different models of support frame 3, the second limiting plate 19 should first be moved away from the first limiting plate 18. After adjusting the position of the two movable blocks 17 by the first screw 15 and the second screw 16, the distance between the first limiting plate 18 and the second limiting plate 19 should be adjusted.

[0033] In addition, multiple first sliders 4 with T-shaped cross sections are fixedly connected to the support frame 3. The mounting frame 1 has a first groove 5 that matches the size of the first sliders 4. A second slider 23 with a T-shaped cross section is fixedly connected to the movable block 17. A second groove 24 that matches the size of the second slider 23 is provided on the mounting plate 7. This arrangement allows the T-shaped structure to limit the slider offset through the double-sided contact surface, ensuring that the support frame 3 and the movable block 17 move only in a straight line along the set direction, avoiding tilting or jamming caused by lateral force during the adjustment process.

[0034] In addition, a motor 11 is fixedly connected to the mounting bracket 1, and a first bevel gear 12 is fixedly connected to the output end of the motor 11. A second bevel gear 13 is fixedly connected to the connecting rod 14. The first bevel gear 12 and the second bevel gear 13 are meshed together. This arrangement can convert the axial rotation of the motor 11 into the radial rotation of the connecting rod 14, thereby driving the two screws to rotate and simultaneously adjusting the position of the two movable blocks 17, further improving the convenience of adjustment.

[0035] Furthermore, a rod 8 is fixedly connected to the mounting plate 7, and a slot 9 is provided on the mounting bracket 1. The depth of the slot 9 is greater than the length of the rod 8, and the end of the rod 8 is fixedly connected to the inner wall of the slot 9 by a spring 10. This arrangement serves two purposes: firstly, when the support bracket 3 is subjected to external vibration or impact, the spring 10 is compressed to absorb energy, reducing the vibration amplitude transmitted to the mounting bracket 1 and preventing bolt loosening or structural deformation caused by rigid connection; secondly, it also makes it easier to pull and reset the mounting plate 7 during disassembly and assembly, improving the convenience of disassembly, assembly, or replacement of the support bracket 3.

[0036] In addition, a rotating ring 21 is rotatably connected to the movable block 17, and a second threaded sleeve 26 is fixedly connected to the rotating ring 21. An adjusting rod 20 is threadedly connected to the second threaded sleeve 26, and a rotating block 22 is fixedly connected to the end of the adjusting rod 20. The rotating block 22 is rotatably connected to the second limiting plate 19. The rotating ring 21 on the movable block 17 is threadedly connected to the adjusting rod 20 through the second threaded sleeve 26. Rotating the adjusting rod 20 can push the second limiting plate 19 to slide along the movable block 17, thereby adjusting the distance between the first limiting plate 18 and the second limiting plate 19. The free rotation of the rotating ring 21 avoids torsional interference between the adjusting rod 20 and the movable block 17, ensuring a smooth adjustment process.

[0037] The top of the mounting bracket 1 is fixedly connected to a rain shield 6. In specific implementation, the rain shield 6 should extend its width to cover the support frame 3 and the top area of ​​the HVAC equipment. The top of the rain shield 6 can be set with an arc structure to guide rainwater and dust to slide to both sides, preventing water from seeping into the equipment or the connection of the support frame 3. The integrated design of the rain shield 6 and the mounting bracket 1 eliminates the need for an additional protective cover, which reduces material costs and avoids external obstructions from affecting the heat dissipation and maintenance of the HVAC equipment.

[0038] It should be noted that since the required positions of the support frame 3 often differ for different models of HVAC equipment, the positions of the two movable blocks 17 can be adjusted using the first screw 15 and the second screw 16 to meet different installation requirements. Furthermore, the size and model of the support frame 3 are also diverse. When using different models of support frame 3, the distance between the first limiting plate 18 and the second limiting plate 19 can be adjusted using the adjusting rod 20 to accommodate support frames 3 of different widths. During assembly and disassembly, simply pull the mounting bracket 1 horizontally to offset the first limiting plate 18 and the second limiting plate 19 horizontally, allowing the support frame 3 to be removed from the mounting bracket 1. Then, release the mounting bracket 1, which will return to its original position under the action of the spring 10.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
