[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0040] Example 1
[0041] like Figure 1-8 The fastening type quick-assembly support assembly shown includes a fixed connector 1, a counterweight 2, a chassis cover 3, and a column tube assembly 4. The fixed connector 1 has an insertion block 11 with an internal thread 111 and a snap fastener 12. The counterweight 2 has an insertion hole 21 with a snap-fit groove 22 that mates with the snap fastener 12. The chassis cover 3 has a limiting post 33 that mates with the snap fastener 12. The bottom of the column tube assembly 4 has an external thread 41 that screws into the internal thread 111. The fixed connector 1 is inserted from the bottom of the counterweight 2, the insertion block 11 is inserted into the insertion hole 21, and the snap fastener 12 is engaged in the snap-fit groove 22. The chassis cover 3 covers the counterweight 2, and the limiting post 33 is inserted into and fixedly connected to the snap fastener 12. The column tube assembly 4 is fixed by screwing the external thread 41 into the internal thread 111.
[0042] Compared with existing technologies, the snap-fit quick-assembly support assembly provided by this utility model has multiple advantages, including screwless structure, simple installation and operation, stable and reliable connection, and low manufacturing cost. By combining plug-in, snap-fit, and threaded connections to replace the traditional screw assembly structure, the number of components and assembly steps are significantly reduced, the assembly process is simplified, and production efficiency is effectively improved. At the same time, the counterweight 2 and the fixed joint 1 are quickly positioned and firmly fastened through the snap-fit 12 and the snap-fit groove 22, allowing the initial assembly of the base to be completed without the need for tools, thus reducing the intensity of manual operation.
[0043] Furthermore, the column tube assembly 4 is fixed with a threaded connection, which not only facilitates quick installation but also ensures the stability of the connection, preventing loosening due to vibration or impact during equipment operation. The overall structure boasts strong stability, effectively supporting the weight of the entire machine and maintaining its normal operating posture, significantly improving the safety and reliability of environmental electrical products in daily use. In addition, the assembly and disassembly of this support assembly are convenient, facilitating later maintenance, replacement, and transportation, comprehensively meeting the modular assembly and efficient manufacturing needs of modern home appliances.
[0044] See Figure 3 , Figure 6 The buckle 12 has an insertion slot 121. When the chassis cover 3 is placed on the counterweight 2, the limiting post 33 is inserted into the insertion slot 121, realizing quick positioning and stable connection between the chassis cover 3 and the counterweight 2. The cooperative design of the insertion structure can effectively simplify the assembly process, improve assembly efficiency, and facilitate subsequent disassembly and maintenance.
[0045] The buckle 12 is further provided with a protrusion 122 on its top. When the limiting post 33 is inserted into the insertion groove 121, the protrusion 122 abuts against the top of the fastening groove 22, thereby providing axial limiting for the fixed joint 1 and effectively preventing it from coming off due to external force or vibration. This structure further enhances the assembly firmness and operational stability of the support components, helping to ensure the structural integrity and safety of the equipment during long-term use.
[0046] Furthermore, a positioning post 13 is provided on the outer side of the fixed connector 1 to limit and prevent rotation during assembly; a positioning groove 23 corresponding to the positioning post 13 is provided in the insertion hole 21. When the fixed connector 1 is inserted from the bottom of the counterweight 2 and the insertion block 11 is inserted into the insertion hole 21, the positioning post 13 and the positioning groove 23 achieve precise alignment and engagement, thereby further improving the positioning accuracy and assembly stability of the component connection. Through this structural design, not only can the fixed connector 1 be prevented from rotating or loosening due to vibration during use, but the structural reliability of the whole machine during operation is also improved, which helps to extend the service life of the product and ensure its long-term stable operation.
[0047] See Figure 7 The counterweight 2 is provided with a boss 25, and the insertion hole 21, positioning groove 23 and fastening groove 22 are all opened on the boss 25.
[0048] In this embodiment, the fastening groove 22 is provided in multiple places and is arranged at intervals along the circumference of the insertion hole 21.
[0049] Furthermore, the outer side wall of the counterweight 2 is provided with a protruding edge 24, and the chassis cover 3 is provided with a fastener 31 that cooperates with the protruding edge 24; the fastener 31 is fastened to the protruding edge 24 to achieve a fixed connection between the chassis cover 3 and the counterweight 2.
[0050] In this embodiment, multiple buckle positions 31 are arranged at intervals along the circumference of the chassis cover 3.
[0051] See Figure 8 The chassis cover 3 has a through hole 32 for allowing the column tube assembly 4 to be installed through it. Multiple limiting posts 33 are provided and arranged at intervals along the circumference of the through hole 32. This circumferential limiting structure achieves multi-point limiting constraints on the fixed joint 1 without affecting the installation of the column tube assembly 4, effectively preventing it from shifting or shaking during use, enhancing the overall stability and impact resistance after assembly, and further improving the structural reliability of the support assembly and the safety of the product.
[0052] Furthermore, the counterweight 2 is a vacuum-formed part, and the mass counterweight is formed by injecting water or concrete; or, the counterweight 2 is a composite material part made by thermoplastic molding process.
[0053] In this embodiment, the bottom of the chassis cover 3 is provided with reinforcing ribs 34, which are radially or annularly distributed. These ribs effectively enhance the overall structural strength and deformation resistance of the chassis cover 3 without significantly increasing material costs. The reinforcing ribs 34 ensure that the chassis cover 3 maintains a stable shape when bearing vertical loads such as the counterweight 2 and the column tube assembly 4, preventing warping and cracking caused by uneven stress at the bottom or external impacts. This further improves the load-bearing capacity and service life of the support components, ensuring the structural stability and reliability of the equipment during long-term operation.

In this embodiment, a fan 5 is mounted on the top of the snap-fit quick-assembly support assembly. By directly mounting the fan 5 to the top of the support assembly, quick positioning and stable connection between the fan 5 and the base can be achieved. The snap-fit and threaded fastening structure used in the support assembly makes the entire assembly process simple and efficient, requiring no additional tools and effectively improving the overall assembly efficiency. Simultaneously, this structure ensures the stability of the fan 5 during operation, preventing shaking or tipping due to insufficient support, thereby enhancing the safety and user experience of the device during use.
[0056] In other embodiments, the top of this snap-fit quick-assembly support assembly can also be fitted with devices such as heaters or air purifiers. This support assembly offers excellent versatility and load-bearing stability, adapting to the installation needs of various electrical appliances. Its quick-assembly structure, combining snap-fit and threaded connections, allows for rapid assembly and secure fixing of equipment without the need for screws or other specialized tools, significantly improving installation efficiency and reducing labor costs. Simultaneously, while maintaining good load-bearing capacity, this structure effectively suppresses the risk of swaying caused by vibration or center of gravity shift, thereby enhancing the stability and safety of the equipment during operation.
[0057] In summary, this new snap-fit quick-assembly support component enables tool-free rapid assembly, significantly simplifying the assembly process, reducing manual labor intensity, and improving production efficiency. Simultaneously, the cooperation between the snap-fit 12 and the limiting post 33 effectively enhances the stability of the connection points, preventing loosening due to long-term use and strengthening the overall safety and reliability of the support structure. Furthermore, this structure facilitates disassembly and reassembly, simplifying maintenance and optimizing space utilization and disassembly efficiency during logistics and transportation, demonstrating significant practical value and promising prospects for wider application.
