CEILING FAN WITH CONVENIENT BLADE INSTALLATION

Description

TECHNICAL FIELD

The present disclosure belongs to the technical field of ceiling fans. Particularly, the present disclosure relates to a ceiling fan with convenient blade installation.

BACKGROUND

In the related technology, during an installation of fan blades of existing ceiling fans, fan blades are fixed onto a blade bracket which is subsequently fixed to the rotating table of the ceiling fan by means of three or four screws usually. The installation procedure of such fan blade structures is complicated, because there is no predetermined blade position, so that a manual judgment and auxiliary tools are required to ensure the angular position of the blades after installation. Overall, the procedure is cumbersome and difficult to operate.

SUMMARY

The present disclosure is intended to at least solve one of the technical problems existing in the existing technology. For this purpose, the present disclosure provides a ceiling fan with convenient blade installation, which simplifies the operation steps of blade installation, requires no auxiliary tools, and improves the efficiency of assembly and disassembly of fan blades.

According to a first aspect of the embodiments of the present disclosure, a ceiling fan with convenient blade installation is provided, including a ceiling fan base configured to be suspended from a ceiling, and a connecting rod connected to a bottom of the ceiling fan base, a drive member being arranged at a bottom of the connecting rod. The ceiling fan further includes a rotating table and a plurality of fan blades, the rotating table being rotatably connected to and driven by the drive member. The rotating table includes a cylindrical mounting disc and a connecting portion configured to be connected to an output end of the ceiling fan, the mounting disc being arranged at a bottom of and coaxial with the connecting portion, the mounting disc having a width greater than that of the connecting portion to form a mounting plate therebetween. The mounting plate is annular and provided, along a circumferential direction, with a plurality of positioning steps having progressively increasing heights, sidewalls of the positioning steps being provided with locking slots. The fan blades are connected to the rotating table. Each of the fan blades includes a blade body and a mounting frame connected to the blade body. The mounting frame is of an open annular structure and provided, at an end thereof adjacent to the blade body, with a locking tab. The plurality of fan blades are sleeved onto the connecting portion in a stacked state and are rotatable about an axis of the rotating table. Each of the plurality of fan blades is arranged at a corresponding one of the positioning steps at different heights such that each locking tab engages with the locking slot at the corresponding height, to pre-fix the fan blades to the rotating table.

According to the embodiments of the present disclosure, at least the following beneficial effects can be achieved. The ceiling fan base is fixed to the ceiling, then the connecting rod and the drive member are fixed, and the rotating table with pre-installed fan blades is connected to the drive member, thereby completing the installation of the ceiling fan. During installation of the fan blades, the mounting frame is passed through an upper portion of the rotating table, namely sleeved onto an outer wall of the connecting portion, such that a bottom surface of the mounting frame abuts against the mounting plate. The blade body is then rotated to drive the mounting frame to rotate about the axis of the rotating table until the locking tab engages with the locking slot, thereby completing the pre-fixation of the fan blades and the rotating table. By adopting the rotating table structure with positioning steps and locking slots, installation of the fan blades becomes simple and quick. A user does not need any auxiliary tools, but only rotates the fan blades to enable the locking tab on the mounting frame to automatically align with and engage into the locking slot of the rotating table, thereby realizing pre-fixation of the fan blades. This greatly simplifies the installation operation steps of ceiling fan blades and improves installation efficiency. Through the precisely designed cooperation between the locking tab and the locking slot, a stable connection is formed between the fan blades and the rotating table, ensuring stability and safety of the ceiling fan during operation. On the other hand, when replacement or maintenance of the fan blades is required, the user only needs to perform a reverse operation to easily detach the fan blades from the rotating table, without the need for laborious disassembly or searching for tools, thereby saving considerable time and effort while improving efficiency of assembly and disassembly.

According to some embodiments of the present disclosure, there are three fan blades. The mounting plate is circumferentially provided with three positioning steps having progressively increasing heights. The three positioning steps have three locking slots circumferentially and evenly distributed along the mounting plate to correspondingly mount the three fan blades.

According to some embodiments of the present disclosure, the three fan blades are sleeved onto the connecting portion in the stacked state and rotatable about the axis of the rotating table, each fan blade corresponding to one of the positioning steps at different heights. After one of the fan blades is mounted onto the corresponding positioning step, an end of the mounting frame opposite to the locking tab is at a height the same as a next lower one of the positioning steps.

According to some embodiments of the present disclosure, the mounting frame is circumferentially provided with three fixing holes equally spaced apart, the mounting plate is correspondingly provided with three fixing grooves, and fasteners pass through the fixing holes and are inserted into the fixing grooves to reinforce the fan blades and the rotating table.

According to some embodiments of the present disclosure, when the locking tabs of three of the mounting frames are respectively engaged in the locking slots, positions of the fixing holes on each of the mounting frames correspond one-to-one with positions of the fixing grooves.

According to some embodiments of the present disclosure, height of the mounting frame gradually increases from the locking tab toward the other end, and the mounting frame spirally surrounds the connecting portion.

According to some embodiments of the present disclosure, the mounting frame is provided, at an end opposite to the locking tab, with a clearance inclined wall.

According to some embodiments of the present disclosure, the locking tab is provided with a guiding inclined surface inclined downward toward the locking slot to guide insertion of the locking tab into the locking slot.

According to some embodiments of the present disclosure, a limiting notch communicating with the locking slot is provided at a top of the positioning step. When the locking tab is inserted into the locking slot, a higher portion of the locking tab extends into the limiting notch and abuts, at a side wall adjacent to the higher portion, against an inner side wall of the limiting notch to prevent disengagement of the locking tab from the locking slot.

According to some embodiments of the present disclosure, a clearance portion is provided between the locking tab and the mounting frame. The clearance portion has a height not greater than a highest portion of the locking tab.

Additional aspects and advantages of the present disclosure will be set forth in part in the description which follows, and in part will become apparent from the description, or may be learned through practice of the present disclosure.

In the related technology, during an installation of fan blades of existing ceiling fans, fan blades are fixed onto a blade bracket which is subsequently fixed to the rotating table of the ceiling fan by means of three or four screws usually. The installation procedure of such fan blade structures is complicated, because there is no predetermined blade position, so that a manual judgment and auxiliary tools are required to ensure the angular position of the blades after installation. Overall, the procedure is cumbersome and difficult to operate.

In order to overcome the technical problems, with reference to FIGS. 1 to 5, a ceiling fan with convenient installation of fan blades 200 according to the present disclosure is provided. The ceiling fan includes a ceiling fan base 300 configured to be suspended from a ceiling and a connecting rod 400 connected to a bottom of the ceiling fan base 300, a drive member is arranged at a bottom of the connecting rod 400. The ceiling fan further includes a rotating table 100 and a plurality of fan blades 200. The rotating table 100 is rotatably connected to and driven by the drive member. The rotating table 100 includes a cylindrical mounting disc 120 and a connecting portion 110 configured to be connected to an output end of the ceiling fan, the mounting disc 120 is arranged at a bottom of and coaxial with the connecting portion 110. The mounting disc 120 has a width greater than that of the connecting portion 110, so as to form a mounting plate 121 therebetween. The mounting plate 121 is annular and is provided, along a circumferential direction, with a plurality of positioning steps 130 having progressively increasing heights. A sidewall of each positioning step 130 is provided with a locking slot 131. A plurality of fan blades 200 are connected to the rotating table 100. Each fan blade 200 includes a blade body 210 and a mounting frame 220 connected to the blade body 210. The mounting frame 220 is of an open annular structure and is provided, at an end thereof adjacent to the blade body 210, with a locking tab 230. The plurality of fan blades 200 are sleeved onto the connecting portion 110 in a stacked state and are rotatable about an axis of the rotating table 100. Each fan blade 200 corresponds to one of the positioning steps 130 at different heights, such that each locking tab 230 engages with the locking slot 131 at the corresponding height, thereby pre-fixing the fan blades 200 to the rotating table 100. It can be understood that the ceiling fan base 300 is fixed to the ceiling, and then the connecting rod 400 and the drive member are fixed. The rotating table 100 with pre-installed fan blades 200 is connected to the drive member to complete installation of the ceiling fan. When installing the fan blades 200, the mounting frame 220 is passed through an upper portion of the rotating table 100, namely sleeved onto an outer wall of the connecting portion 110, such that a bottom surface of the mounting frame 220 abuts against the mounting plate 121. The blade body 210 is then rotated to drive the mounting frame 220 to rotate about the axis of the rotating table 100 until the locking tab 230 engages with the locking slot 131, thereby completing pre-fixation of the fan blades 200 and the rotating table 100. By adopting the rotating table 100 structure with positioning steps 130 and locking slots 131, installation of the fan blades 200 becomes simple and quick. A user does not need any auxiliary tools, but only rotates the fan blade 200 to enable the locking tab 230 on the mounting frame 220 to automatically align with and engage into the locking slot 131 of the rotating table 100, thereby realizing pre-fixation of the fan blades 200. This greatly simplifies the installation operation steps of the ceiling fan blades 200 and improves installation efficiency. Through the precisely designed cooperation between the locking tab 230 and the locking slot 131, a stable connection is formed between the fan blades 200 and the rotating table 100, ensuring stability and safety of the ceiling fan during operation. On the other hand, when replacement or maintenance of the fan blades 200 is required, the user only needs to perform a reverse operation to easily detach the fan blades 200 from the rotating table 100, without the need for laborious disassembly or searching for tools, thereby greatly saving time and effort while also improving efficiency of assembly and disassembly.

Referring to FIG. 1, three fan blades 200 are provided. The mounting plate 121 is circumferentially provided with three positioning steps 130 having progressively increasing heights, and the locking slots 131 of the positioning steps 130 are circumferentially and evenly distributed along the mounting plate 121 to correspondingly mount the three fan blades 200. Further, the three fan blades 200 are sleeved onto the connecting portion 110 in a stacked state, each fan blade 200 corresponding to one of the positioning steps 130 at different heights. When one fan blade 200 is mounted onto the positioning step 130, an end of the mounting frame 220 opposite to the locking tab 230 is at a height the same as a next lower one of the positioning steps 130, thereby facilitating installation of the next fan blade 200. By providing three fan blades 200 and the corresponding three positioning steps 130, the airflow of the ceiling fan becomes more uniform, thereby improving air circulation. Meanwhile, the uniform distribution of the fan blades 200 and the positioning steps 130 also makes the appearance of the ceiling fan more aesthetically pleasing. The stacked installation manner not only saves space but also makes installation of the fan blades 200 more orderly. Furthermore, by designing the height of the mounting frame 220 to increase progressively layer by layer, interference between the fan blades 200 is avoided, thereby improving installation efficiency.

Referring to FIGS. 1, 3, and 4, the mounting frame 220 is provided with through fixing holes 221, and the mounting plate 121 is correspondingly provided with fixing grooves 122. During installation of the fan blades 200, fasteners (such as screws) may pass through the fixing holes 221 and be inserted into the fixing grooves 122, thereby reinforcing the connection between the fan blades 200 and the rotating table 100. The reinforcement manner using fasteners further enhances the stability of the connection between the fan blades 200 and the rotating table 100. Even under extreme conditions (such as excessive wind force or vibration), the fan blades 200 are not prone to detachment or loosening, thereby improving durability and safety of the ceiling fan. After the three mounting frames 220 are respectively fixed to the rotating table 100 through engagement of the locking tabs 230 with the locking slots 131, the three fixing holes 221 thereon, which are evenly distributed, still correspond one-to-one with the positions of the fixing grooves 122 on the annular mounting plate. Therefore, by means of only three fasteners, installation and fixation of the three fan blades 200 can be completed, thereby further reducing the number of fasteners used and improving installation efficiency.

Referring to FIGS. 1, 2, and 3, the height of the mounting frame 220 is designed to gradually increase from the locking tab 230 toward the other end, so as to form a spiral surrounding shape with respect to the connecting portion 110. This enables the fan blades 200 to be stacked layer by layer during installation, with the height of each mounting frame 220 progressively increasing, thereby avoiding interference during the installation process and making the installation process smoother. This not only avoids interference during installation but also improves stability of the installed fan blades 200. In addition, the spiral surrounding arrangement of the connecting portion 110 makes the fan blades 200 more balanced during rotation, thereby reducing vibration and noise.

Referring to FIGS. 2 and 3, the mounting frame 220 is provided, at an end opposite to the locking tab 230, with a clearance inclined wall 222. The clearance inclined wall 222 serves to provide sufficient space for the locking tab 230 to be inserted into the locking slot 131 during installation of the fan blades 200, and ensures that no interference occurs with other components during installation. The design of the clearance inclined wall makes installation of the fan blades 200 smoother, reduces resistance during the installation process, and allows the user to complete installation more easily. By ensuring smooth installation, the clearance inclined wall reduces potential safety hazards caused by improper installation and improves safety in use of the ceiling fan.

Referring to FIGS. 2 and 3, specifically, in order to make installation of the fan blades 200 smoother, the locking tab 230 is provided with a guiding inclined surface 231 inclined downward toward the locking slot 131. During installation of the fan blades 200, the guiding inclined surface 231 guides the locking tab 230 to smoothly extend into the locking slot 131. The guiding inclined surface 231 reduces resistance during the installation process and also improves installation accuracy of the fan blades 200, thereby avoiding safety hazards caused by improper installation.

Referring to FIGS. 2 and 4, a limiting notch 132 communicating with the locking slot 131 is provided at a top of the positioning step 130. When the locking tab 230 is inserted into the locking slot 131, a higher portion of the locking tab 230 extends into the limiting notch 132, and the locking tab 230, at a side wall adjacent to the higher portion, abuts against an inner side wall of the limiting notch 132, thereby restricting the locking tab 230 from disengaging from the locking slot 131. This further enhances the stability of the connection between the fan blades 200 and the rotating table 100. Even under strong wind conditions, the fan blades 200 are not prone to detachment, thereby improving safety performance of the ceiling fan.

Referring to FIGS. 2 and 3, a clearance portion 232 is provided between the locking tab 230 and the mounting frame 220. The clearance portion 232 has a height not greater than a highest portion of the locking tab 230, so as to provide sufficient space for the locking tab 230 to extend into the locking slot 131 during installation, making installation of the fan blades 200 more flexible and convenient. At the same time, due to the height limitation of the clearance portion 232, interference with other components during installation is avoided.

The above embodiments of the present disclosure have been described in detail in conjunction with the accompanying drawings. However, the present disclosure is not limited to the above embodiments. Within the knowledge scope of ordinary technicians in the relevant field, various modifications may be made without departing from the spirit of the present disclosure.
