Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a connecting mechanism for folding fan blades and a ceiling fan with folding fan blades. Background Technology

[0002] Currently, ceiling fans are a very popular type of fan product. Many of them can extend the fan blades when the fan starts and retract them when the fan stops, by using the inertia of rotation, in the horizontal direction, which is the vertical direction of the fan shaft.

[0003] Because this type of structure usually integrates the chandelier body structure into the fan body, it is suitable for using the large surface area on the top and bottom to house the fan blades. Although this type of fan has a dynamic fan blade opening and closing effect, its large flat structure and the vertical structure of the ceiling fan rod make it inconvenient to package and transport. Usually, the fan blades, body and rod need to be packaged separately, so users have to assemble them themselves after purchase before they can install and use them, making installation and use not much easier.

[0004] Furthermore, since the fan blades are controlled by the rotation and stillness of the fan body, the fan blades do not have a position locking function. Therefore, the fan blades are prone to failure in retraction and extension due to various reasons such as improper assembly or quality issues at the moving joints. Moreover, the fan blades will generate corresponding vibrations during the operation of the fan, which can easily lead to continuous friction and minor collisions at the joints, resulting in abnormal noises and other issues. This not only affects the quietness of daily use but also poses potential safety hazards. Utility Model Content

[0021] refer to Figures 1-4 A connecting mechanism for a folding fan blade according to an embodiment of the present utility model includes a base component 1, a base noise-reducing component 2, a support component 3, a support noise-reducing component 4, a fan blade connecting seat 5, and a positioning component 6; The base component 1 is used to be installed on the fan body 9. The base 1 is provided with a shaft connection hole for rotatably connecting the support component 3 in the horizontal direction. The base 1 is also provided with a locking part 11 for cooperating with the positioning component 6. The base silencing component 2 is used to be disposed at one end of the support component 3 connected to the base component 1. The base silencing component 2 is located between the support component 3 and the base component 1 to fill the gap and / or increase the contact area. A positioning component 6 passes through the base component 1, the base silencing component 2 and the support component 3 respectively, and the positioning component 6 is used in conjunction with the locking part 11 to limit the position of the support component 3 on the base component 1. The support silencing component 4 is installed on the support component 3, and the fan blade connecting seat 5 is rotatably connected to the support component 3 in the horizontal direction. The support silencing component 4 is located between the support component 3 and the fan blade connecting seat 5 to fill the gap and / or increase the contact area. Another positioning component 6 passes through the fan blade connecting seat 5, the support silencing component 4 and the support component 3 respectively. The fan blade connecting seat 5 is provided with at least two locking holes 51 in different positions for cooperating with the positioning component 6. The fan blade connecting seat 5 is fixed on the support component 3 by cooperating with the positioning component 6 through the locking holes 51. The fan blade connecting seat 5 is used to connect the fan blade 8, so the fan blade 8 can rotate along the support member 3 with the fan blade connecting seat 5 in the horizontal direction as the axial direction. At the same time, the fan blade 8 can be fixed in the corresponding position by the positioning member 6 between the support member 3 and the fan blade connecting seat 5 engaging with the locking port 51. Similarly, the support member 3 can rotate around the base member 1 in the horizontal direction, and the position of the support member 3 can be locked by the locking member 6 between the base member 1 and the support member 3 to achieve adjustment and fixation. Therefore, the fan blade 8 is equivalent to having two-stage joints on the fan body 1, thereby being able to be adjusted from a horizontal position to a vertical position parallel to the fan's suspension rod. So, the fan blades on one fan body 9 The fan blades are arranged axially so that they can be fully unfolded into a horizontal position by hand during use. When storage is needed or after the fan is pre-assembled, the blades can be folded into a column shape. Therefore, the entire fan can be pre-assembled and packaged at the factory, and the entire fan can be stored conveniently without disassembly, effectively reducing space occupation. Moreover, the base silencing component 2 and the support silencing component 4 increase the contact at the connection and reduce the gap, which can effectively prevent noise from the connection due to vibration and friction, while ensuring the connection reliability of the folding fan blade connection mechanism. The base silencing component 2 and the support silencing component 4 can be made of materials such as plastic, carbon fiber, silicone, and ceramic.

[0022] refer to Figure 1 and 2For example, the support member 3 is a strip structure with a U-shaped axial cross-section. The support member 3 has shaft connection holes on both sides of the plate structure at both axial ends, respectively for rotatably connecting the fan blade connecting seat 6 and the base member 1. The support noise reduction member 4 has a receiving groove 41 that matches any of the straight plate structures on both sides of the support member 3, and the support noise reduction member 4 also has clearance holes corresponding to the shaft connection holes connecting the support member 3 and the fan blade connecting seat 6. The U-shaped support member 3 facilitates the use of screws, bolts, shafts, etc. The installation is easy to pass through, and it is also easy to assemble with the base muffler 2, base 3, support muffler 4 and fan blade connecting seat 5. It is also easy to process and form, for example, metal plates can be formed by bending or stamping. Moreover, the support muffler 4 can be a single unit, with two support mufflers 4 respectively fitting the plate-like structures on both sides of the support 3 through the receiving groove 41. The support muffler 4 can also be a single component with two receiving grooves 41 that simultaneously fit the plate-like structures on both sides of the support 3. Thus, each component has good design flexibility or assembly flexibility.

[0023] refer to Figure 1 and 2 For example, the supporting muffler 4 is a frame-shaped shell with receiving grooves 41 on both sides. The supporting muffler 4 has fitting parts 42 extending from both sides towards the middle, which can be matched and inserted into the inner side of the supporting member 3. The bottom inner side of the supporting member 3 has a matching protrusion 31 that matches the inner diameter of the fitting part 42. During assembly, the supporting muffler 4 can be more conveniently fitted onto both sides of the supporting member 3 from the U-shaped opening side through the receiving grooves 41, and the corresponding fitting parts 42 can be used to fit the corresponding matching protrusions 31. The matching protrusions 31 and the fitting parts 42 can be configured as axial structures with a circular, rectangular or other cross-sectional shape. Since the supporting muffler 4 and the supporting member 3 form a closed structure after combination, it has better structural strength and support. The structure of the fitting part 42 greatly enhances the structural performance of the supporting muffler 4. refer to Figure 1 and 2 For example, the supporting silencing component 4 is provided with a laterally extending reinforcing rib 43 near the relief hole, which further ensures the structural strength of the supporting silencing component 4 at the rotatable connection between the supporting component 3 and the fan blade connecting seat 5. refer to Figure 1 and 2For example, the fan blade connecting seat 5 is a strip structure with a U-shaped axial cross section. The middle part of the plate-like structure on both sides of the fan blade connecting seat 5 is provided with a support hole 52 for rotatably connecting with the support member 3. The fan blade connecting seat 5 is rotatably connected to the end of the support member 3 through the support hole 52. The middle part of the fan blade connecting seat 5 is provided with a connecting hole 8 for connecting the fan blade. Each fan blade connecting seat 5 has at least two locking holes 51, which are respectively located in front of and behind the support hole 52 on either the left or right side of the fan blade connecting seat 5. Thus, when the fan blade connecting seat 5 is rotated relative to the support member 3, it can be fixed in position by engaging with the positioning member 6 through the locking holes 51.

[0024] refer to Figures 1-3 For example, the fan blade connecting seat 5 is connected to a cover plate 7 in a quick-release manner. The two sides of the fan blade connecting seat 5 are provided with locking holes 53. The cover plate 7 is provided with locking hooks 71 that match the locking holes 53. By quickly installing and removing the cover plate 7, the inner side of the fan blade connecting seat 5 and the support member 3 can be covered by the cover plate 7 when the fan blade 8 is unfolded. This not only improves the appearance but also reduces the entry of dust. At the same time, it can be easily removed when folding the fan blade, which is very convenient.

[0025] refer to Figure 1 , 2 For example, the base silencing component 2 is a rectangular frame structure. The base silencing component 2 is fitted and connected to one end of the support component 3. The base silencing component 2 is provided with a clearance hole to allow for the rotational connection between the base 1 and the support component 3. The base silencing component 2 is also provided with a through hole 61 for the positioning component 6. By fitting the base silencing component 2 around a section of the support component 3 before connecting it to the base 1, the structural strength and firmness of the support component 3 at the connection point are enhanced, and the structure of the base silencing component 2 is more durable and stable. refer to Figure 1 , 2 For example, the base component 1 has support plates 12 erected on both sides for rotatably connecting the support component 3. The locking part 11 is provided on the support plate 12. The support plate 12 is also provided with a limiting protrusion 13, which is used to limit the contact between the base muffler 2 and / or the support component 3. The base component 1 is also provided with a mounting part 14 for connecting the fan body 9 by bolts. The two support plates 12 on both sides of the base component 1 can have large openings to facilitate assembly operations. At the same time, the limiting protrusion 13 can block the support component 3 from reaching the corresponding position during adjustment. Thus, the positioning part 6 cooperates with the locking part 11 to fix the component. refer to Figure 1 and 2For example, the positioning member 6 includes a support rod 61, a spring 62, a button 63, and a locking piece 64. One end of the support rod 61 is mounted on the support member 3, and the button 63 is mounted on the other end of the support rod 61. The spring 62 is movably connected to the support rod 61. One end of the spring 62 abuts against or connects to the support member 3 or the support rod 61, and the other end of the spring 62 abuts against or connects to the button 63. The button 63 is provided with a locking part that matches and locks the locking part 11 and the locking port 51. As a preferred structure in the figure, the end of the support member 3 connected to the base member 1 and the middle part of the support member 3 are respectively provided with limiting holes for connecting one end of the support rod 61. The other side of the support member 3 is respectively provided with holes that allow at least the front end of the button 63 to pass through. The button 63 is secured by a C-shaped locking piece. 64. A protrusion or other limiting structure can restrict the button to move along the support rod 61 into the support member 3 only by pressing it; otherwise, it will be reset by the spring 62. The locking part 11 is an arc-shaped groove corresponding to the path of rotation of the support member 3 around it. The arc-shaped groove matches the snap-fit ​​part of the button 63. At least one end of the arc-shaped groove corresponding to the unfolded position of the fan blade is provided with a snap-fit ​​end that matches the peripheral wall of the button 62. The snap-fit ​​part is a journal. Therefore, as long as the button 62 is pressed so that the journal with an outer diameter smaller than the peripheral wall of the button 62 falls into the arc-shaped groove, the support member 3 and the base muffler 2 can rotate. The locking port 51 is an Ω-shaped or straight notch, which locks the position of the fan blade connecting seat 5 in the same way as conventional ones. The operation only requires a simple press, which is very convenient. This structure is easy to assemble. Of course, common locking structures such as screws, bolts, and locking pins can also be used as positioning parts 6. refer to Figures 1-4 For example, a ceiling fan with folding blades according to an embodiment of the present invention includes a fan body 9, fan blades 8 and a connecting mechanism for the folding fan blades. The base 1 is connected to the upper side of the fan body 9, and the fan blades 8 are connected to the fan blade connecting seat 5. When the fan blades 8 are folded, they change from a horizontal position to a vertical position on the outer periphery of the fan body 9, making the ceiling fan form a compact columnar structure. It is very easy to store and place the entire fan in a packaging box without disassembly, so it can be pre-assembled directly, which greatly facilitates users' purchase and use. Moreover, the connecting structure is noiseless when the fan blades are unfolded, making it both quiet and durable.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
