Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan equipment technology, specifically to a quick-installation structure for a fan blade mounting base and a fan blade. Background Technology
[0002] Taking fan lights as an example, one type is the open-blade fan with fixed, non-retractable blades. In open-blade fans, the blades are fixed to the blade sheath, and the position of the blades relative to the blade sheath does not change regardless of whether it is in airflow mode. Open-blade fans have a relatively simple structure, low cost, long blades, and large airflow, and still have a large market.
[0003] Considering transportation and storage needs, the fan blades and the blade holders are separate for open-blade fans. The fan blades are only fixed to the blade holders when the fan reaches the consumer and needs to be installed.
[0004] In existing technology, the specific fixing method involves driving multiple screws (usually three) onto each fan blade to lock the blades to the blade sheath. However, a fan has at least three blades, meaning that installing a single fan requires at least nine screws for the consumer, resulting in low installation efficiency and high labor costs. This is especially true in some overseas markets where installation labor costs are even higher, making the installation cost of flap fans very high. Utility Model Content
[0005] The purpose of this utility model is to provide a quick installation structure for a fan blade mounting base and a fan blade, aiming to solve the problems in the prior art where additional tools are required for fan blade installation, and the installation process is complicated and inefficient.
[0006] To achieve the above objectives, this utility model provides a quick-installation structure for a fan blade mounting base and a fan blade, comprising: a fan blade mounting base, the fan blade mounting base including a hollow cylinder and a disk, the hollow cylinder being vertically and concentrically disposed on the disk, the outer periphery of the disk being provided with a plurality of slots opening in the horizontal direction, each slot having an upwardly protruding boss on its bottom groove surface; and a fan blade, one end of the fan blade having a plug-in end for inserting into the slot, the bottom of the plug-in end having a locking groove for engaging with the boss.
[0007] Furthermore, the boss is a right-angled trapezoidal boss, and the inclined surface of the boss is set towards the slot opening of the slot.
[0008] Furthermore, the hollow cylinder, disk, several slots, and boss are integrally formed.
[0009] Furthermore, it also includes a connecting shell, the interior of which has a downward-opening mounting cavity, in which a mounting plate is fixedly connected. The center of the disc has a vertically extending upward-reaching connecting sleeve, and a rotating shaft is inserted through the connecting sleeve. The upper end of the rotating shaft is fixedly connected to the mounting plate, and the lower end of the rotating shaft is inserted through the disc.
[0010] Furthermore, a connecting sleeve is concentrically provided at the lower end of the mounting plate, and the upper end of the rotating shaft is fastened to the connecting sleeve.
[0011] Furthermore, a ring motor is provided on the inner wall of the hollow cylinder, and a circuit control board is connected to the upper end face of the mounting plate, the circuit control board being electrically connected to the ring motor.
[0012] Furthermore, the lower end of the rotating shaft is provided with a connecting end cover, which is spaced apart from the lower end surface of the disk.
[0013] Furthermore, the connecting sleeve and the disk are integrally formed, and the connecting sleeve is provided with a bearing connected to the rotating shaft.
[0014] Furthermore, the upper end face of the disk is spaced apart from the lower end face of the outer shell.
[0015] This utility model provides a quick-installation structure for a fan blade mounting base and a fan blade. Compared with the prior art, the outer periphery of the disc of the fan blade mounting base is provided with several horizontally oriented slots. One end of the fan blade is provided with a plug-in end that matches the slot.

[0028] like Figures 1 to 3 As shown, a quick-installation structure for a fan blade mounting base and a fan blade includes a fan blade mounting base 10 and a fan blade 20.
[0029] The fan blade mounting base 10 includes a hollow cylinder 11 and a disk 12. The hollow cylinder 11 is vertically and concentrically mounted on the disk 12. The outer periphery of the disk 12 is provided with a plurality of horizontally oriented slots 13. Each slot 13 has an upwardly protruding boss 131 on its bottom groove surface. The boss 131 is a right-angled trapezoidal boss 131, and the inclined surface of the boss 131 is set towards the groove opening of the slot 13.
[0030] One end of the fan blade 20 is provided with a plug end 21 for inserting into the slot 13, and the bottom of the plug end 21 is provided with a slot 211 for engaging with the boss 131.
[0031] In practice, users only need to align the plug end 21 of the fan blade 20 with the slot 13 and push it in. The guide slope of the boss 131 and the slot 211 are elastically engaged to complete the limiting and fixing, which can ensure smooth installation and achieve reliable locking. No additional installation tools and accessories are required, making the installation convenient and quick, effectively improving installation efficiency and saving installation costs.
[0032] In this embodiment, the hollow cylinder, disc 12, several slots 13, and boss 131 are integrally formed. The fan blade mounting base 10 is injection molded and ejected as a single piece, facilitating mass production. Furthermore, the fan blade 20 is also injection molded and ejected as a single piece, enabling mass production and improving production efficiency.
[0033] like Figure 4 As shown, in this embodiment, a connecting shell 30 is also included. The connecting shell 30 has a downward-opening mounting cavity 31 inside. A mounting plate 32 is fixedly connected inside the mounting cavity 31. A connecting sleeve 121 extending upward is vertically provided at the center of the disc 12. A rotating shaft 122 is provided through the connecting sleeve 121. The upper end of the rotating shaft 122 is fixedly connected to the mounting plate 32, and the lower end of the rotating shaft 122 is provided through the disc 12.
[0034] In specific implementation, the top of the connecting housing 30 is provided with a ceiling connecting component, the mounting cavity 31 is provided with a number of screw connecting posts, the mounting plate 32 is horizontally set in the mounting cavity 31 and fixed by screw connecting posts, the upper end face of the disc 12 is spaced apart from the lower end face of the housing, and the disc 12 of the fan blade mounting seat 10 is connected to the mounting plate 32 through the rotating shaft 122 passing through the connecting sleeve 121, so that the fan blade mounting seat 10 can rotate after being connected to the connecting housing 30.
[0035] In this embodiment, a connecting sleeve 321 is concentrically provided at the lower end of the mounting plate 32. The connecting sleeve 321 and the mounting plate 32 are an integral structure, and the upper end of the rotating shaft 122 is fastened to the connecting sleeve 321 by threads.

[0038] In this embodiment, a connecting end cap 40 is provided at the lower end of the rotating shaft 122. The connecting end cap 40 is spaced apart from the lower end surface of the disk 12 and does not affect the rotation of the fan blade mounting base 10. This end cap can serve as a decorative component, covering the lower end of the rotating shaft 122.
[0039] In this embodiment, the connecting sleeve 121 and the disk 12 are an integral structure. The connecting sleeve 121 is provided with a bearing connected to the rotating shaft 122. The rotating shaft 122 rotates within the connecting sleeve 121 through the bearing.

One end of the fan blade 20 is provided with a plug-in end 21 that is adapted to the slot 13. Through the cooperative structure design of the slot 13 and the plug-in end 21, the user only needs to align the plug-in end 21 of the fan blade 20 with the slot 13 and push it in. The guide slope of the boss 131 and the elastic engagement of the slot 211 complete the limiting and fixing, which can ensure smooth installation and achieve reliable locking. No additional installation tools and accessories are required, making installation convenient and quick, effectively improving installation efficiency and saving installation costs.
