Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to a fan rotation positioning structure. Background Technology

[0002] Most existing fan oscillation heads use a rotating positioning mechanism to adjust the fan's pitch angle. The existing rotating positioning structure mostly uses a positioning plate and a top ball to achieve this. However, the existing design does not produce a crisp sound. For European and American customers, they mainly judge the quality of a product by the sound emitted when the rotating connection structure is turned. Therefore, there is a need for a fan rotating positioning structure that is simple in structure, has a stable positioning, and produces a crisp sound when rotating. Utility Model Content

[0003] The main purpose of this utility model is to provide a fan rotation positioning structure that is simple in structure, stable in positioning, and produces a crisp sound when rotating.

[0004] This utility model proposes a fan rotation positioning structure, including an arc-shaped positioning plate, a positioning component, and a positioning spring;

[0005] The bottom of the fan support base is provided with an arc-shaped support base connecting groove, and the positioning plate is snapped into the support base connecting groove. The positioning plate is provided with a plurality of positioning plate positioning holes set at equal angles.

[0006] The top of the fan support column is provided with a support column connecting groove. The positioning member and the positioning spring are disposed in the support column connecting groove. The positioning spring is disposed between the bottom of the positioning member and the bottom of the inner side of the support column connecting groove. The relative state between the fan support base and the fan support column is maintained by the cooperation of the positioning spring, the positioning member and the positioning plate.

[0007] Preferably, the positioning element is a combined top bead, which includes a positioning post and a top bead body. The top bead body is fixedly connected to the top of the positioning post, and part of the top bead body extends out from the top of the positioning post.

[0008] Preferably, the positioning hole of the positioning plate is a strip-shaped hole, and the width of the positioning hole of the positioning plate is adapted to the width of the part of the top bead body extending from the top of the positioning post, so that the positioning post can impact the positioning plate.

[0009] Preferably, the depth of the positioning hole of the positioning plate is adapted to the height of the part of the top bead body extending from the top of the positioning post, so that the top bead body can hit the bottom of the positioning hole of the positioning plate.

[0010] The beneficial effects of the fan rotation positioning structure of this utility model are as follows:

[0011] 1. By setting a positioning spring, the positioning component can be driven to reset and strike the positioning plate, resulting in a crisp sound.

[0012] 2. The number of positioning holes on the positioning plate is greater and denser than before, making it smoother to replace the positioning parts with the corresponding positioning holes and reducing noise when the positioning parts slide between the positioning holes.

[0013] 3. The depth and width of the positioning hole of the positioning plate are matched with the depth and width of the part of the top bead body that extends from the top of the positioning post, so that the sound emitted meets the requirements and the positioning stability is guaranteed.

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] Reference Figures 1 to 6 An embodiment of the fan rotation positioning structure of this utility model is proposed:

[0024] A fan rotation positioning structure includes an arc-shaped positioning plate 1, a positioning element 2, and a positioning spring 3.

[0025] The bottom of the fan support base 4 is provided with an arc-shaped support base connecting groove 41. The positioning plate 1 is snapped into the support base connecting groove 41. The positioning plate 1 is provided with five positioning plate positioning holes 11 set at equal angles. The positioning plate positioning holes 11 are strip-shaped holes.

[0026] The top of the fan support column 5 is provided with a support column connecting groove 51. The positioning element 2 and the positioning spring 3 are disposed within the support column connecting groove 51. The positioning spring 3 is disposed between the bottom of the positioning element 2 and the bottom of the inner side of the support column connecting groove 51. The positioning element 2 is a combined top ball, which includes a positioning column 21 and a top ball body 22. The top ball body 22 is fixedly connected to the top of the positioning column 21, and part of the top ball body 22 extends out from the top of the positioning column 21. Through the cooperation of the positioning spring 3, the positioning element 2, and the positioning plate 1, the relative state between the fan support base 4 and the fan support column 5 is maintained.

[0027] The width of the positioning hole 11 on the positioning plate is adapted to the width of the portion of the top ball body 22 extending from the top of the positioning post 21, so that the top edge of the positioning post 21 can impact the positioning plate 1. The depth of the positioning hole 11 on the positioning plate is adapted to the height of the portion of the top ball body 22 extending from the top of the positioning post 21, so that the top ball body 22 can impact the bottom of the positioning hole 11 on the positioning plate.
