Description

Technical Field

[0001] This application relates to the field of fan technology, and in particular to a fan grille mounting structure and a fan. Background Technology

[0002] Fan guards are typically installed on the outside of the fan blades to protect them from injury during rotation. Traditional fan guards consist of a front guard and a rear guard, and are usually secured with screws. The process involves first fitting the flat rings at the openings of the front and rear guards together, then passing screws through the through holes formed in the flat rings. This cumbersome disassembly and installation process results in high manual assembly costs. Furthermore, the exposed screws are prone to corrosion and rust, affecting the quality of the fan guard. Additionally, the small size of the screws makes them susceptible to loss during frequent disassembly and reassembly.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0026] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0027] To address the technical problems in the prior art, this application provides a fan grille mounting structure and a fan, which enables the buckles to be fixed to the front grille by riveting during production. The riveted buckles are not easy to fall off and are easy to assemble. Simply align the positioning holes of the front and rear grilles and unscrew the buckles to fasten them. It has the advantages of easy installation and disassembly, and simple and reliable assembly.

[0028] Please see Figures 1-2 This utility model provides a fan guard installation structure, which includes a front guard 1 and a rear guard 2. Specifically, the front guard 1 and the rear guard 2 are preferably circular in shape. The outline of the front guard 1 is provided with a buckle 3, which is connected to the front guard 1 by riveting. Specifically, the buckle 3 is preferably made of metal, but it can also be made of plastic, and no special limitation is made here.

[0029] Specifically, the buckle 3 includes a first buckle plate 31, a second buckle plate 32, and a third buckle plate 33 formed by integral modeling. The end of the first buckle plate 31 is riveted to the outline ring of the front mesh cover 1. The first buckle plate 31 and the second buckle plate 32 are set perpendicularly, and the third buckle plate 33 is set perpendicularly to the second buckle plate 32. The first buckle plate 31 and the third buckle plate 33 are set facing each other. When the front mesh cover 1 and the rear mesh cover 2 are aligned and the buckle 3 is screwed down to fasten, the second buckle plate 32 contacts the top surface of the outline ring of the front mesh cover 1 and the top surface of the outline ring of the rear mesh cover 2.

[0030] Furthermore, the contour rings of the front mesh cover 1 and the rear mesh cover 2 are symmetrically provided with positioning holes 4. By aligning the positioning holes 4, the buckle 3 is unscrewed and fastened to the front mesh cover 1 and the rear mesh cover 2. The riveted buckle 3 is not easy to fall off, and it is easy to assemble. Simply align the positioning holes 4 of the front mesh cover 1 and the rear mesh cover 2 and unscrew the buckle 3 to fasten it. It has the advantages of easy installation and disassembly, and simple and reliable fit.

[0031] Please see Figure 2 The second snap plate 32 is generally L-shaped. One side of the first snap plate 31 is perpendicularly positioned along the long edge of the second snap plate 32, and the bottom edge of the third snap plate 33 is perpendicularly positioned on the opposite side of the long edge of the second snap plate 32. The short panel of the second snap plate 32 is convenient for the user to grip and tighten.

[0032] The third snap plate 33 is convex in shape, with its convex top 331 positioned away from the long edge of the second snap plate 32. The convex top 331 is designed to increase the contact surface for a secure fastening while minimizing material waste.

[0033] The first buckle plate 31 is shaped like a key panel, and the side of the first buckle plate 31 that is not connected to the second buckle plate 32 forms a raised surface 311. The reason for designing the raised surface 311 is that the increased contact surface is conducive to a secure fastening, while also avoiding excessive waste of design material costs.

[0034] This utility model also provides a fan, which includes the above-described fan guard mounting structure.

[0035] The working principle and usage of this utility model:

[0036] In use, simply align the positioning holes 4 of the front mesh cover 1 and the rear mesh cover 2, hold the short panel of the second buckle plate 32, and unscrew the buckle 3 to fasten it, so that the long panel of the second buckle plate 32 contacts the top surface of the outline ring of the front mesh cover 1 and the top surface of the outline ring of the rear mesh cover 2, the protruding surface 311 of the first buckle plate 31 contacts the side of the outline ring of the front mesh cover 1, and the third buckle plate 33 contacts the side of the outline ring of the rear mesh cover 2. In this way, the fan mesh cover can be easily installed. When disassembling, simply reverse the operation.
