Description

Technical Field

[0001] This application relates to a fan connection component and a fan, and is applicable to the technical field of fans. Background Technology

[0002] The threads between existing fan connectors typically use, for example... Figure 10 The standard thread shown is used to connect components such as bases and columns. Because standard threads have sharp angled ends, these angled areas are prone to wear, inevitably leading to loosening of the fit and decreased sealing. Furthermore, this type of standard thread with sharp angled ends only has two hypotenuses of a triangle engaging, resulting in a small total mating surface area. For these two reasons combined, existing standard thread connections with sharp angled ends suffer from unreliable connections and poor stability.

[0003] However, in existing technologies, due to the technical biases and design habits of those skilled in the art, the technical defects of ordinary threads are addressed by increasing the length of the threaded connection, without considering improvements to the thread structure itself. Increasing the length of the threaded connection inevitably requires a sufficient number of rotations, such as up to ten or more, to achieve a secure connection, increasing the difficulty and complexity of operation, as well as material and processing costs.

[0004] For example, Chinese patent CN201507483U discloses a structure for installing an electric fan column tube and chassis. In this structure, the column tube is connected to the chassis by threads. The threads of the column tube and the chassis are ordinary threads, which makes the threaded connection between the column tube and the chassis unreliable and prone to shaking, seriously affecting the user experience of the product. In addition, the threaded connection between the column tube and the chassis requires multiple rotations to be fully connected, resulting in low installation efficiency. Utility Model Content

[0005] The purpose of this application is to design a fan connection assembly and a fan, wherein the connecting parts are connected by trapezoidal threads or sawtooth threads with a large tooth pitch, which makes the threaded connection between the connecting parts more reliable, more stable, less prone to wear, and improves installation efficiency.

[0006] This application relates to a connection assembly, which includes a first connector and a second connector; the first connector and the second connector are connected by a thread; the thread is a trapezoidal thread or a sawtooth thread.

[0007] In some implementations, the thread pitch is 5.8 mm to 6.2 mm.

[0008] In some implementations, the tooth tip width of the thread is 2.8 mm to 3.3 mm.

[0009] In some embodiments, the first connector is a connecting post and the second connector is a base; the connecting post is provided with a threaded section and the base is provided with a threaded hole; the threaded section and the threaded hole are respectively provided with trapezoidal threads or sawtooth threads.

[0010] In some implementations, the length of the threaded section is 17.4 mm to 18.6 mm.

[0011] In some implementations, the base is a disc structure; the threaded hole is located at the center of the base.

[0012] In some embodiments, the base includes an upper base and a lower base, which are joined together by a coupling.

[0013] In some implementations, the base is provided with a counterweight; the counterweight is also provided with a threaded hole, and the threaded section is connected to the threaded hole of the counterweight.

[0014] In some implementations, the counterweight is connected to the base via studs or snap-fit ​​structures.

[0015] This application also provides a fan, including a connecting component, which is the connecting component described above.

[0016] The fan connection assembly and fan proposed in this application have the following technical advantages: (1) The connecting components of the fan proposed in this application are connected by trapezoidal threads or sawtooth threads, which makes the threaded connection between the connecting components more reliable, more wear-resistant, and has better stability and sealing. (2) The fan connection component proposed in this application, by designing the specific thread segment, pitch and tooth tip width installation dimensions of the thread, makes the threaded connection between the connecting parts tighter and improves stability; it can significantly reduce the number of rotations required during connection and reduce the length of the threaded connection segment, thereby reducing processing costs and operating costs; (3) The fan proposed in this application has a counterweight with a threaded hole on the base, and the threaded section on the column is connected to the threaded hole of the counterweight, which makes the fan support more stable and less prone to shaking, and can effectively improve the user experience of the product.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0029] like Figure 1-2 , Figure 6 As shown, this application proposes a fan connection assembly, including a first connector and a second connector. The first connector can be a connecting post 1 or an extended post 5; the second connector can also be a connecting post 1 or a base 2. The first connector and the second connector are connected by threads to achieve detachability. As shown in Figures 7-9, in the connection assembly proposed in this application, the thread connecting the first connector and the second connector is a trapezoidal thread or a sawtooth thread. Because trapezoidal threads or sawtooth threads have a larger pitch and a wider tooth tip width, the threaded engagement surface area between the first connector and the second connector is larger, the meshing is more reliable, and the stability is better, which can significantly reduce the number of rotations required when connecting the connectors. In addition, because the tooth tip of the trapezoidal thread or sawtooth thread is horizontal, it is less prone to wear than ordinary threads, the mating surface will not loosen, and the sealing performance is better. Those skilled in the art will know that, Figure 7As shown, a thread whose two inclined sides slope outwards to opposite sides is called a trapezoidal thread. Figure 8-9 As shown, a thread in which one of the two inclined sides is perpendicular or both inclined sides are inclined to the same side is called a sawtooth thread.

[0030] like Figure 1-4 As shown in Figures 7-9, in some embodiments, the first connecting member designed in this application can be a connecting post 1, and the second connecting member can be a base 2. The thread pitch a is designed to be 5.8mm to 6.2mm, preferably 5.90mm, 6.00mm, or 6.05mm. The thread crest width b is designed to be 2.8mm to 3.3mm, preferably 2.9mm, 3.1mm, or 3.2mm. The depth of the threaded hole 21 is designed to be 18.2mm-19.6mm. One end of the connecting post 1 is provided with a threaded section 11, the length c of which is designed to be 17.4mm-18.6mm, and the length of the threaded section in the threaded hole 21 is 18.2mm-19mm. The thread profile angle can be designed to be 55° to 65°, preferably 60°. By adopting the above-mentioned design of the threaded section, pitch, and crest width, the fit between the threaded section and the threaded hole is tighter, and the thread crest is less prone to wear. The threaded section 11 only needs to be rotated two or three times to achieve a quick connection with the threaded hole 21, making the operation simpler and faster. The mating surface between the threads is also larger, allowing the connecting post 1 to be firmly installed on the base 2, reducing the likelihood of wobbling and improving stability. At the same time, the length of the threaded section can be reduced, thereby lowering processing and operating costs.

[0031] like Figure 1-4 As shown, in some embodiments, the first connector designed in this application can be a connecting post 1, and the second connector can be a base 2. The diameter r of the first connector is 76.2 mm to 80.2 mm, preferably 77.9 mm, 78.2 mm, 79.6 mm, or 80.00 mm. By adopting the above-mentioned connector diameter r design, combined with the above-mentioned thread segment, pitch, and tooth tip width design, the fit between the connecting post 1 and the base 2 is tighter, and the overall structure is more stable.

[0032] like Figure 1-2 As shown in Figure 4, in some embodiments, the first connecting member can be a connecting post 1, and the second connecting member can be a base 2. One end of the connecting post 1 is provided with a threaded section 11, and the base 2 is provided with a threaded hole 21. The threads of the threaded section 11 and the threaded hole 21 are respectively the trapezoidal thread or the sawtooth thread mentioned above. By adopting the above scheme, the connecting post can be stably connected to the base, forming a more stable support structure.

[0033] like Figure 1-2As shown in Figure 4, in some embodiments, the thread on the threaded section 11 of the connecting column 1 can be an external thread; correspondingly, the thread on the threaded hole 21 on the base 2 is an internal thread, which makes it convenient for the connecting column 1 to be rotated and connected to the base 2, and facilitates disassembly and assembly.

[0034] like Figure 1-2 As shown, in some embodiments, the base 2 can be a disc structure. Specifically, the threaded hole 21 is located at the center of the base 2, which makes the connecting post 1 more balanced when installed in the threaded hole 2 and less prone to displacement.

[0035] like Figure 1-5 As shown, in some embodiments, the base 2 includes an upper base 22 and a lower base 23; wherein the upper base 22 and the lower base 23 are joined together by a connector. The connector is preferably a snap fastener; specifically, snap fasteners 24 are evenly distributed in the circumferential direction of the upper base 22 and the lower base 23, so that a more stable base structure can be formed by connecting them.

[0036] like Figure 1-5 As shown, in some embodiments, the base 2 is provided with a counterweight 4, which also has a threaded hole, so that the threaded section 11 of the connecting column 1 can connect with the threaded hole of the counterweight 4. The threaded hole of the counterweight 4 has the aforementioned trapezoidal thread or sawtooth thread. The counterweight 4 is connected to the base 2 by a stud 3 or a snap-fit ​​structure, which increases the stability of the base 2. The counterweight 4 has multiple slots evenly distributed in the circumferential direction, and the base 2 has multiple hooks correspondingly distributed in the circumferential direction. The base 2 and the counterweight 4 can be connected by snapping the hooks into the slots. The counterweight 4 and the base 2 are respectively provided with stud holes at their middle positions. Specifically, when installing the base 2, the chassis 2 and the counterweight 4 can be guided by the stud 3 to achieve pre-positioning, then fixed by snapping the hooks into the slots, and finally tightening the stud 3 to achieve overall fixation of the chassis and the counterweight.

[0037] refer to Figure 2 As shown, in some embodiments, the base 2 and the counterweight 4 are both disc structures. The counterweight 4 is fitted inside the base 2 and is concentrically positioned with the base 2. A threaded hole is also provided at the center of the counterweight 4, and a connecting hole is provided on the base 2. The threaded section 11 of the connecting column 1 can pass through the connecting hole and connect with the threaded hole of the counterweight. Because the counterweight 4 is heavier, it can more stably support the connecting column 1, improving stability.

[0038] like Figure 6As shown, this application also proposes a fan, including a connecting assembly, which is the connecting assembly described above. Specifically, the fan proposed in this application further includes a body 6, which can be mounted on the connecting post 1 or the extension post 5 of the connecting assembly. The extension post 5 and the connecting post 1 are threaded together, and the thread is the trapezoidal thread or sawtooth thread described above, which will not be elaborated further here. By using the above-described connecting assembly, the fan's support is more stable, less prone to wear and wobbling, and can effectively improve the user experience.

[0039] Although the embodiments disclosed in this application are as described above, the content is merely for the purpose of facilitating understanding of this application and is not intended to limit this application. Any person skilled in the art to which this application pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this application; however, the scope of patent protection of this application shall still be determined by the scope defined in the appended claims.
