Description

Technical Field

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

[0002] The existing technology has the following shortcomings in the locking structure design of the fan guard:

[0003] Traditional screw connections are complex: Many fan grilles rely on screws for fixing, and installation and removal require tools, making the process cumbersome and time-consuming, thus reducing the user experience. For example, some designs achieve locking through a combination of fastening rings and clips (such as patent CN202707557U), but its structure relies on mechanical linkages and slots, still requiring manual adjustment of the position, and it is prone to loosening due to vibration after long-term use.

[0004] Insufficient reliability of buckle locking: Existing buckle structures (such as patent CN222879974U) usually adopt single-point locking or rigid connection, lacking elastic buffer design, which can easily cause buckle deformation or failure due to external impact or long-term vibration, posing a risk of the mesh cover falling off.

[0005] In existing technologies, the removal of the mesh cover usually requires manually unlocking the clips or rotating the parts, which is a complicated process. Especially in space-constrained environments (such as wall-mounted fans or compact devices), users find it difficult to complete the removal quickly. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fan grille locking structure, which aims to solve the problems in the background art.

[0007] In order to achieve the above-mentioned utility model objectives, the first aspect of this utility model proposes a fan guard locking structure, including a front guard and a rear guard, wherein the rear guard is provided with a plurality of fixing grooves;

[0008] The front mesh cover is provided with a fixing post corresponding to the position of the fixing groove. The fixing post can be inserted into the fixing groove by rotating the front mesh cover to achieve axial positioning.

[0009] The front mesh cover is also provided with an elastic mesh cover locking buckle, and the rear mesh cover is fixedly connected with a limit clip;

[0010] When the fixing post is inserted into the fixing groove, the mesh cover locking buckle engages with the limiting clip to achieve radial locking.

[0011] Optionally, the rear mesh cover is provided with an elastic support column, and the elastic support column and the limiting clip are used to limit the mesh cover locking buckle, and the elastic support column is supported on the mounting surface of the mesh cover locking buckle.

[0012] Optionally, the elastic support column is integrally formed with the rear mesh cover, and a U-shaped movable groove is formed on the rear mesh cover along the periphery of the elastic support column.

[0013] Optionally, the limiting clip is integrally formed with the front mesh cover, and a U-shaped movable groove is formed on the front mesh cover along the periphery of the limiting clip.

[0014] Optionally, the fixing groove is integrally formed inside the rear mesh cover, and the opening of the fixing groove gradually increases in size.

[0015] Optionally, at least three fixing slots and three fixing posts are provided, and they are distributed at equal intervals on the rear and front mesh covers.

[0016] Optionally, when the outer wall of the front mesh cover located on the elastic support column is pressed, the mounting surface of the mesh cover locking buckle of the elastic support column moves, causing the mesh cover locking buckle to disengage from the limiting clip. Beneficial effects

[0017] 1. This utility model discloses a fan grille locking structure. By rotating and engaging the fixing posts on the front grille with the fixing grooves on the rear grille, quick alignment and initial positioning are achieved, avoiding the complex operations of traditional screw connections. The snap-fit ​​design of the elastic buckle and the limiting clip provides additional constraint, preventing radial displacement of the grille due to vibration or external force, significantly improving structural stability. Through the synergistic effect of multi-point locking (at least three fixing posts / grooves) and the elastic buckle, the locking force is more uniform, and the impact resistance is stronger.

[0018] 2. This utility model provides a fan grille locking structure that compresses the elastic support column by pressing the outer wall of the front grille, causing the buckle to disengage from the limiting clip and achieving one-click unlocking without tools or complicated operations. The combination of rotation and pressing is ergonomic, making it particularly suitable for installation environments with limited space, significantly improving user convenience.

[0030] Reference Figures 1-4 An embodiment of the present invention provides a fan guard locking structure, including a front guard 1 and a rear guard 2, wherein the rear guard 2 is provided with a plurality of fixing grooves 3;

[0031] The front mesh cover 1 is provided with a fixing post 4 corresponding to the position of the fixing groove 3. The fixing post 4 can be inserted into the fixing groove 3 by rotating the front mesh cover 1 to achieve axial positioning.

[0032] The front mesh cover 1 is also provided with an elastic mesh cover locking buckle 5, and the rear mesh cover 2 is fixedly connected with a limiting clip 6;

[0033] When the fixing post 4 is inserted into the fixing groove 3, the mesh cover locking buckle 5 engages with the limiting clip 6 to achieve radial locking.

[0034] When the outer wall of the front mesh cover 1 located on the elastic support column 7 is pressed, the mounting surface of the elastic support column 7 supports the mesh cover locking buckle 5 to move, causing the mesh cover locking buckle 5 to disengage from the limiting clip 6.

[0035] It should be noted that the cooperation between the fixing post 4 and the fixing groove 3 achieves axial alignment of the front mesh cover 1 and the rear mesh cover 2, while the engagement of the mesh cover locking buckle 5 and the limiting clip 6 further prevents radial displacement of the mesh cover, ensuring structural stability. Assembly and disassembly can be completed without tools; users can lock or unlock the mesh cover by rotating the front mesh cover 1, improving the user experience. The mesh cover locking buckle 5 further positions the mesh cover, ensuring the firmness of the installation of the front mesh cover 1 and the rear mesh cover 2, and preventing the mesh cover from loosening due to vibration.

[0036] When the user presses on the outer wall of the front mesh cover 1, the top of the elastic support column 7 is squeezed, and its supporting surface pushes the mounting surface of the mesh cover locking buckle 5 to move. The snap-fit ​​end of the mesh cover locking buckle 5 disengages from the limiting clip 6 due to the movement of the mounting surface, thereby releasing the radial locking. At this time, the user can rotate the front mesh cover 1 to remove the mesh cover.

[0037] The lock can be released with a simple press, requiring no additional tools and significantly improving disassembly efficiency. The pressing action is directly linked to the locking / unlocking function, eliminating the need for users to learn complex operating procedures.

[0038] In some embodiments, the rear mesh cover 2 is provided with an elastic support column 7, and the elastic support column 7 and the limiting clip 6 are used to limit the mesh cover locking buckle 5, and the elastic support column 7 is supported on the mounting surface of the mesh cover locking buckle 5.

[0039] It should be noted that an elastic support column 7 is added to the inner wall of the rear net cover 2. The elastic support column 7 and the limiting clip 6 work together to limit the mounting surface of the net cover locking clip 5.

[0040] The bottom of the elastic support column 7 is fixedly connected to the rear net cover 2, and the top contacts the mounting surface of the net cover locking buckle 5. When the net cover locking buckle 5 is engaged with the limiting clip 6, additional support force can be provided by pressing the elastic support column 7 to disengage the net cover locking buckle 5 from the limiting clip 6, and then the front net cover 1 can be rotated to facilitate the removal of the front net cover 1.

[0041] In some embodiments, the elastic support column 7 is integrally formed with the rear mesh cover 2, and a U-shaped movable groove is formed on the rear mesh cover 2 along the periphery of the elastic support column 7.

[0042] It should be noted that the elastic support column 7 and the rear mesh cover 2 are integrally molded using injection molding. A U-shaped movable groove is formed on the inner wall of the rear mesh cover 2 along the periphery of the elastic support column 7. The opening direction of the U-shaped movable groove is consistent with the movement direction of the elastic support column 7, allowing the elastic support column 7 to undergo limited deformation under stress, thereby adjusting the mounting surface height of the mesh cover locking buckle 5.

[0043] In some embodiments, the limiting clip 6 is integrally formed with the front mesh cover 1, and a U-shaped movable groove is formed on the front mesh cover 1 along the periphery of the limiting clip 6.

[0044] It should be noted that the limiting clip 6 is integrally formed with the front mesh cover 1, and is processed by stamping or injection molding. A U-shaped movable groove is formed on the inner wall of the front mesh cover 1 along the periphery of the limiting clip 6. The design of the U-shaped movable groove provides the limiting clip 6 with a certain amount of movement space, reducing the risk of fatigue fracture during long-term use.

[0045] In some embodiments, the fixing groove 3 is integrally formed inside the rear mesh cover 2, and the opening of the fixing groove 3 gradually increases in size.

[0046] It should be noted that the opening of the fixing groove 3 gradually widens, forming a guide slope, which facilitates the sliding of the fixing post 4 into the fixing groove 3. The gradually widening opening design of the fixing groove 3 facilitates the quick alignment and insertion of the fixing post 4, reducing assembly time. The fixing groove 3 and the rear mesh cover 2 are integrally molded using an injection molding process to ensure the structural strength of the groove.

[0047] In some embodiments, at least three fixing grooves 3 and fixing posts 4 are provided respectively, and are distributed at equal intervals on the rear net cover 2 and the front net cover 1.

[0048] It should be noted that at least three fixing slots 3 and fixing posts 4 are provided, and they are evenly distributed in the circumferential direction of the rear net cover 2 and the front net cover 1.

[0049] The equally spaced fixing grooves 3 and fixing columns 4 can evenly distribute the load and ensure the overall strength.

[0050] In practical applications, the front mesh cover 1 and the rear mesh cover 2 are axially aligned through the cooperation of the fixing post 4 and the fixing groove 3. The opening of the fixing groove 3 gradually widens, facilitating the insertion of the fixing post 4 and completing the initial positioning. Simultaneously, the elastic mesh cover locking buckle 5 on the front mesh cover 1 engages with the limiting clip 6 on the rear mesh cover 2, forming a radial lock to prevent the mesh cover from shifting due to vibration or external force. To enhance the stability of the buckle, the rear mesh cover 2 is equipped with an elastic support post 7, whose bottom is integrally formed with the rear mesh cover 2, and whose top supports the buckle mounting surface. A U-shaped movable groove allows for elastic deformation to accommodate tolerances. When disassembly is required, the user presses the outer wall of the front mesh cover 1, compressing the elastic support post 7 and pushing the buckle mounting surface to move, causing the mesh cover locking buckle 5 to disengage from the limiting clip 6, releasing the radial lock. Then, rotating the front mesh cover 1 allows for separation.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
