Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, and specifically to a ceiling fan that is easy to maintain. Background Technology

[0002] For example, Chinese Patent CN213392801U discloses a household ceiling fan that is easy to assemble and disassemble. While it solves the problem that "ceiling fans are installed on the ceiling of most homes, and the installation of ceiling fans usually involves installing a hook on the ceiling, hanging the fan on the hook, and then binding it with steel wire. During the use of the ceiling fan, it will shake, and after a long period of use, it will affect the binding effect of the steel wire. Moreover, the steel wire will rust or even break after a long period of use, which may affect the stability of the ceiling fan installation. Furthermore, the rusted steel wire makes the ceiling fan difficult to disassemble," it overlooks the fact that the blade angle of most ceiling fans used in industrial plants is fixed at the factory and cannot be adjusted according to actual usage needs. Existing ceiling fans with adjustable blade angles mostly require manual disassembly and individual adjustment of the blade angles, which is cumbersome and makes it difficult to ensure the consistency of multiple blade angles, increasing the workload and time cost of maintenance personnel.

[0003] Based on this, this utility model designs a ceiling fan that is easy to maintain in order to solve the above problems. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a ceiling fan that is easy to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

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

[0025] In some embodiments, please refer to the accompanying drawings. Figures 1-6A ceiling fan designed for easy maintenance includes a mounting block 1, a mounting head 2, and fan blades 3. The mounting head 2 is mounted on the top surface of the mounting block 1. The fan blades 3 are circumferentially distributed on the outer side of the mounting block 1. A cavity 4 is formed inside the mounting block 1. A first bevel gear 5 is rotatably connected to the bottom surface of the cavity 4. A second bevel gear 6 is circumferentially distributed and meshed with the outer surface of the first bevel gear 5. A threaded rod 17 is fixedly connected to the end of the second bevel gear 6 away from the cavity 4. A threaded groove is formed on the side of the fan blades 3 near the mounting block 1, which is threaded to the threaded rod 17. A symmetrical guide groove 20 is formed on the end of the fan blades 3 near the mounting block 1. A guide rod 19 is inserted into the inner wall of the guide groove 20. An angle support assembly is provided between the end of the guide rod 19 away from the fan blades 3 and the mounting block 1. An operating assembly for driving the first bevel gear 5 to rotate is provided on the bottom surface of the first bevel gear 5.

[0026] In some embodiments, such as Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the operating component includes an adjusting column 8 fixed to the bottom surface of the first bevel gear 5, a through-type circular groove 7 is provided on the bottom surface of the cavity 4, the outer surface of the adjusting column 8 is rotatably connected to the inner wall of the circular groove 7 by a bearing ring, and the bottom end of the adjusting column 8 extends to the bottom surface of the mounting block 1. The first bevel gear 5 can be rotated by rotating the adjusting column 8.

[0027] In some embodiments, such as Figures 1-4 As shown, in a preferred embodiment of this utility model, the angle support assembly includes a connecting disc 15 circumferentially distributed on the outer surface of the mounting block 1. The end of the threaded rod 17 passes through the center of the connecting disc 15. A groove 18 is formed on the surface of the connecting disc 15. The end of the guide rod 19 away from the fan blade 3 is slidably connected to the inner wall of the groove 18. A stop block 21 is fixedly connected to the eccentric part of the inner wall of the groove 18. A symmetrical annular groove 22 is formed on the inner wall of the groove 18. A sliding plate 23 is fixedly connected to the end of the guide rod 19 away from the fan blade 3. The sliding plate 23 is slidably connected to the annular groove 22. The straight section of the sliding plate 23... The diameter is larger than that of the guide rod 19 to prevent slippage on the inner wall of the annular groove 22. When the guide rod 19 rotates forward along the inner wall of the slide groove 18, the slide plate 23 slides on the inner wall of the annular groove 22. Then the slide plate 23 gradually moves away from the stop block 21, thereby achieving the effect of stabilizing the adjustment of the angle of the fan blade 3. When the slide plate 23 rotates toward the position of the stop block 21, the rotation of the guide rod 19 can be restricted when the stop block 21 contacts the slide plate 23. At this time, the threaded rod 17 can rotate normally, so that the fan blade 3 and the threaded rod 17 present a threaded straight guiding effect, which facilitates the simultaneous disassembly of the fan blade 3.

[0028] In some embodiments, such as Figures 2-4As shown, in a preferred embodiment of this utility model, the inner wall of the cavity 4 is provided with a circumferentially distributed second groove 13, and the outer surface of the mounting block 1 is provided with a rotating groove 14 communicating with the second groove 13. The end of the rotating groove 14 away from the mounting block 1 extends through the surface of the connecting plate 15. A bearing 16 is fixedly connected to the inner wall of the rotating groove 14. The diameter of the second groove 13 is larger than the diameter of the second bevel gear 6. This structure allows the rotation of the threaded rod 17 to be stable. Simultaneously, the larger diameter of the second groove 13 compared to the second bevel gear 6 facilitates the spacing of each second bevel gear 6, avoiding... To prevent collisions, the outer surface of the adjusting column 8 is provided with a thread 10, and an anti-slip fastening sleeve 11 is fitted on the outer surface of the adjusting column 8. The anti-slip fastening sleeve 11 is threadedly connected to the thread 10. After adjusting the device by rotating the adjusting column 8, the anti-slip fastening sleeve 11 can be screwed onto the thread 10 from the smooth part of the adjusting column 8 until the top surface of the anti-slip fastening sleeve 11 fits against the top surface of the first groove 12. The bottom surface of the mounting block 1 is provided with a first groove 12, and the diameter of the first groove 12 is larger than the diameter of the circular groove 7 and the anti-slip fastening sleeve 11. A baffle 9 is fixedly connected to the bottom surface of the adjusting column 8.

[0029] When using this device, first ensure the ceiling fan is powered off to guarantee safe operation. Then, hold the adjusting column 8 and rotate it, causing the first bevel gear 5 to rotate in the cavity 4. As the first bevel gear 5 rotates, the meshing, circumferentially distributed second bevel gear 6 is also driven to rotate. The second bevel gear 6 drives the threaded rod 17, which is fixedly connected to it, to rotate. Simultaneously, one end of the guide rod 19 is inserted into the guide groove 20 of the fan blade 3, and the other end, the sliding plate 23, slides in the annular groove 22 on the inner wall of the sliding groove 18 of the connecting plate 15. The guide rod 19 is parallel to the threaded rod 17, serving a guiding function. As the first bevel gear 5 rotates... When the threaded rod 17 rotates, the fan blade 3 rotates with the threaded rod 17 through the threaded connection between the threaded groove and the threaded rod 17. Under the constraint of the guide groove 20 and the annular groove 22, the guide rod 19 ensures that the fan blade 3 rotates smoothly and realizes the synchronous adjustment of the angle of the fan blade 3. After the fan blade 3 is adjusted to a suitable angle, the anti-slip fastening sleeve 11 on the outer surface of the adjusting column 8 is rotated so that it is screwed into the thread 10 from the smooth part of the adjusting column 8 until the top surface of the anti-slip fastening sleeve 11 is in contact with the top surface of the first groove 12 on the bottom surface of the mounting block 1, thereby fixing the adjusting column 8 and preventing the fan blade 3 from changing angle due to accidental rotation of the first bevel gear 5.

[0030] When it is necessary to disassemble the fan blade 3, hold the adjusting column 8 and rotate it in the opposite direction to drive the first bevel gear 5 to rotate in the opposite direction, which in turn causes the second bevel gear 6 and the threaded rod 17 to rotate in the opposite direction. When the threaded rod 17 rotates in the opposite direction, the slide plate 23 at one end of the guide rod 19 rotates to contact the stop block 21 at the eccentric position of the inner wall of the slide groove 18. The slide plate 23 is limited by the stop block 21. At this time, the guide rod 19 remains in a horizontal state and cannot continue to rotate. Since the guide rod 19 cannot rotate, while the threaded rod 17 continues to rotate in the opposite direction, according to the threaded connection relationship between the threaded groove of the fan blade 3 and the threaded rod 17, the fan blade 3 moves in a straight line along the threaded rod 17, gradually moving away from the mounting block 1, until it is completely removed from the threaded rod 17, thus achieving the simultaneous disassembly of the fan blade 3.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
