DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example

[0034] See Figures 1 to 5 As shown, a fan lamp with multiple blades that rotate synchronously and snaps in place, includes a hanger 1, a fan motor 2 fixed to the bottom end of the hanger and a fan disk 3 fixed to the main shaft of the fan motor, a plurality of blades 4 are provided on the fan disk, and a lamp 5 is provided below the fan disk. In this embodiment, the number of the blades is three, four or five; the above structures are all conventional structures of the prior art and are simply applied, so they are not recorded in detail.

[0035] In this embodiment, the fan disk has an annular groove 6 on its top surface, and several insertion slots 7 on its side that communicate with the annular groove. The number of these insertion slots matches the number of fan blades. Several limiting rods 8 are integrally mounted on the top of the annular groove, positioned on either side of the insertion slots. The insertion slots are primarily for inserting the ends of the fan blades, while the limiting rods are primarily used to limit the position of the rotating ring against the snap protrusion after rotation, preventing it from shifting upward and ensuring the precise positioning of the snap protrusion and the C-shaped snap groove, as well as ensuring smooth and reliable installation.

[0036] In actual use, the top surface of the fan disk is provided with a rotating ring 9. In actual use, the rotating ring is a plastic or metal structure. The bottom edge of the rotating ring is integrally formed with raised portions 10, the number of which matches the number of card slots. Reinforcement ribs 18 are provided between the inner wall of the rotating ring and the top surface of the raised portion. A snap protrusion 11 is provided on the bottom side of the raised portion. The raised portion is mainly used to insert into the annular groove, while the snap protrusion is mainly used to rotate and snap into the C-shaped snap groove and abut against the upper limit of the limit support rod to ensure the stability and reliability of the installation with the C-shaped snap groove. The width of the C-shaped snap groove matches the width of the end of the snap protrusion, so that it will not shift or shake after snapping.

[0037] In actual use, the ends of the fan blades are fixed with insertion tabs 12, and the sides of the insertion tabs are provided with C-shaped snap grooves 13. During assembly, the insertion tabs are inserted into the insertion slots and extend into the annular grooves. The rotating ring is attached to the top surface of the fan disk, and the protrusions are located in the annular grooves. The rotating ring is rotated, and the snap projections snap into the bottom surface of the limiting support rods, and the ends of the snap projections snap into the C-shaped snap grooves to position the fan blades. This structure allows for simultaneous installation and positioning of multiple fan blades, improving the convenience and effectiveness of assembly and disassembly, and is highly practical. The fan blades are not easily loosened or fall off.

[0038] In actual use, the fan disk is equipped with a locking screw 14 on its side. During use, the protrusion rotates within the annular groove and is locked in place by the locking screw. This is mainly used to prevent the rotating ring from rotating without external force, thereby ensuring smooth and reliable installation and preventing the locking protrusion from disengaging from the C-shaped locking groove.

[0039] In actual application, a snap spring 15 is provided in the annular groove; the end of the snap spring is on the top edge of the card insertion slot, and the other end of the snap spring is tilted downward; a buckle protrusion 16 is fixed to the top surface of the card insertion protrusion; in this embodiment, the other end of the snap spring is tilted downward, so that the snap spring can be deformed after the card insertion protrusion is inserted, and it can be pressed against the outer side surface of the buckle protrusion to prevent the card insertion protrusion from detaching from the card insertion slot. During assembly, the card insertion protrusion passes through the card insertion slot, and the end of the snap spring presses against the outer end surface of the buckle protrusion to prevent the fan blade from detaching.

[0040] In actual use, the distance between the top surface of the snap-on protrusion and the bottom surface of the rotating ring matches the height of the limiting rod; the limiting rod is locked between the snap-on protrusion and the rotating ring to limit the position. This structure ensures that the snap-on protrusion will not shift upward after assembly, ensuring a stable and reliable snap-on connection with the C-shaped snap-on groove.

[0041] In actual application, a protective cover 17 is provided on the upper part of the boom, and the protective cover is positioned on the top surface of the rotating ring to provide protection and improve the overall appearance.

[0042] The present invention has positive effects: the structure of the present invention is reasonable, and an annular groove is provided on the top surface of the fan disk and cooperates with the limiting support rod, and a card slot is provided on the side of the fan disk, and a rotating ring is provided on the top surface of the fan disk, and a protrusion and a snap protrusion are provided on the edge of the bottom surface of the rotating ring, and cooperate with the card protrusion with a C-shaped snap groove on the fan blade. During assembly, all the fan blades are respectively placed in different card slots, and then the rotating ring is attached to the top surface of the fan disk and rotated so that the end of the snap protrusion is inserted into the C-shaped snap groove, which can synchronously complete the positioning of multiple fan blades and improve the efficiency of assembly. Moreover, the snap protrusion is limited by the limiting support rod, which can also ensure the smooth and reliable installation of the rotating ring. It is easy to operate and stable and reliable to use, which is conducive to improving the efficiency of disassembly and assembly, and convenient for inspection and maintenance operations. At the same time, it will not rust, which improves the effectiveness of use and is highly practical.

[0043] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
