A hanger arm hook hole is arranged at the upper portion of the boom. The lower portion of the hanger arm is hook-shaped and is inserted into the hanger arm hook hole to suspend the boom. The upper portion of the hanger arm is fixedly connected with the hanger arm mounting rack. At least two elastic buckles are arranged on the inner wall of the boom sliding hole of the upper decorative cover. The diameters of the clamping holes formed by the elastic buckles in the downward direction are smaller than the outer diameter of the boom in the natural state. When the elastic buckles slide out of the boom, they return to the natural state and are clamped on the upper end surface of the boom.

[0007] In the improved scheme of the above-mentioned integrated invisible fan lamp, the elastic buckles are four and are uniformly distributed on a 360-degree circumference.

[0008] In the improved scheme of the above-mentioned integrated invisible fan lamp, the lower surface of the clamping position of the elastic buckle is a guide slope.

[0009] In the improved scheme of the above-mentioned integrated invisible fan lamp, a blocking pin is arranged at the outer end of the hook at the lower portion of the hanger arm.

[0010] In the improvement scheme of the above-mentioned integrated invisible fan lamp, the motor shaft of the motor assembly is connected with the hanger rod through a flange; locking screws are screwed on the flange; the flange and the lower end of the hanger rod are both provided with a bolt hole into which a bolt can be inserted.

[0011] In the improvement scheme of the above-mentioned integrated invisible fan lamp, the fan blade folding structure is a torsion spring, the positioning ends of the two ends of which are arranged on the blade disc and the fan blade respectively; a shaft sleeve is sleeved on the blade rotating shaft of the blade disc; the shaft sleeve protrudes from the shaft sleeve hole of the fan blade after being sleeved into the shaft sleeve hole; a fan blade fixing screw with a spacer is screwed on the blade rotating shaft; the spacer is tightly arranged on the shaft sleeve, so that the fan blade swings around the shaft sleeve to be unfolded or folded.

[0012] Compared with the prior art, the utility model has the advantages that: the hook of the lower part of the hanger arm is inserted into the hanger arm hook hole of the hanger rod, the hanger rod is hung, at least two elastic buckles are arranged on the inner wall of the hanger rod sliding hole of the upper decorative cover, the diameters of the clamping holes formed by the elastic buckles in the downward direction are smaller than the outer diameter of the hanger rod in the natural state, the elastic buckles can be buckled on the upper end surface of the hanger rod in the natural state after elastic return when sliding out of the hanger rod, so that at least two decorative cover fixing screws are not needed to be screwed from the lower part of the upper decorative cover to the hanger rod to fix, the fixing of the upper decorative cover is simpler and easier, the appearance of the fan lamp is not affected by the exposed decorative cover fixing screws, the structure of the utility model is more reasonable, the installation of the upper decorative cover is simpler and easier, and the overall appearance is improved.

[0020] Figure 7 This is a perspective view of the upper decorative cover according to an embodiment of the present utility model. Detailed Implementation

[0021] An integrated, concealed fan light, such as Figures 1 to 7 As shown, the device includes a blade disk 1, multiple fan blades 2 mounted on the blade disk 1, a fan blade retraction structure 3 that causes the fan blades 2 to close onto the blade disk 1, a motor assembly 4 installed in the blade disk 1, a suspension rod 5 connected to the motor shaft 41 of the motor assembly 4, a boom 6, a boom mounting bracket 7, an upper decorative cover 8, a lamp disk located at the lower part of the blade disk 1 and fixedly connected to the lower end of the motor shaft 41 of the motor assembly 4, and a lamp plate and lampshade mounted on the lamp disk. The lamp disk, lamp plate, and lampshade are not shown in the figure. Their structure and installation method are basically the same as those of current concealed fan lights, and will not be described in detail here. The difference is that: a boom hook hole 51 is provided on the upper part of the suspension rod 5; the lower part of the boom 6 is hook-shaped and passes through the boom hook hole 51 to suspend the suspension rod 5, and the upper part is fixedly connected to the boom mounting bracket 7 (usually welded together); in the... At least two elastic buckles 82 are provided on the inner wall of the sliding hole 81 of the upper decorative cover 8. When all the elastic buckles 82 are in their natural state, the diameter of the hole formed by them in the top view is smaller than the outer diameter of the hanging rod 5. When the elastic buckles 82 are fitted onto the outer wall of the hanging rod, they deform slightly outward under the action of the outer wall and then lock onto the outer wall. When the elastic buckles 82 slide upward out of the hanging rod 5, they return to their natural state after elastic reset and are fastened to the upper end face 52 of the hanging rod 5. In this way, it is not necessary to use at least two decorative cover fixing screws to be screwed in radially from both sides of the lower part of the upper decorative cover to fix it against the hanging rod. This makes the fixing of the upper decorative cover 8 simpler and easier, and avoids affecting the aesthetics of the fan light due to the exposed decorative cover fixing screws. Therefore, the structure of this utility model is more reasonable, making the installation of the upper decorative cover simpler and easier, and improving the overall aesthetics of the fan light. The notch between two adjacent elastic buckles 82 not only allows the buckles to deform slightly under force, but also avoids the hook part of the boom.

[0022] When installing the fan light, first put the upper decorative cover 8 on the hanging rod 5 and slide it down so that the upper part of the hanging rod 5 is exposed. Then install and fix the hanging arm mounting bracket 7, which is connected to the hanging arm 6, to the ceiling. Next, insert the hook 61 at the bottom of the hanging arm 6 through the hanging arm hook hole 51 to suspend the hanging rod 5. Finally, slide the upper decorative cover 8 up so that the elastic buckle 82 slides out of the upper end of the hanging rod and is fastened to the upper end face 52 of the hanging rod 5. At this time, the upper decorative cover 8 will not slide down the hanging rod and thus cover the hanging arm 6 and the hanging arm mounting bracket 7.

[0023] In this embodiment, as Figure 7 As shown, there are four elastic buckles 82, evenly distributed on a 360-degree circumference. This ensures that opposite notches are in a straight line, facilitating the attachment of the hook at the bottom of the boom to the boom rod. Of course, there can also be three or five elastic buckles 82. Preferably, the lower surface of the buckle 82 is a guide slope 821.

[0024] Preferably, a stop pin 9 is provided at the outer end of the hook 61 at the lower part of the boom 6. Here, the stop pin 9 is an elastic pin.

[0025] In this embodiment, as Figure 3 , 4 The motor shaft 41 of the motor assembly 4 is connected to the boom 5 via a flange 10; a locking screw 101 is screwed onto the flange 10; both the flange 10 and the boom 5 have pin holes 102 and 53 at their lower ends for inserting a pin 20; here, the pin 20 is a resilient pin.

[0026] The fan blade retraction structure 3 can be a synchronous retraction structure composed of commonly used gear rings, gears, and tension springs. In this embodiment, such as... Figure 5 , 6 As shown, when the machine stops working, each fan blade retracts independently. The fan blade retraction structure 3 is a torsion spring, with its two positioning ends respectively located on the blade disk 1 and the fan blade 2. A bushing 12 is fitted on the blade shaft 11 of the blade disk 1. After the bushing 12 is fitted into the bushing hole 21 of the fan blade 2, it protrudes above the bushing hole 21. A fan blade fixing screw 30 with a spacer 301 is screwed onto the blade shaft 11. After the spacer is tightly attached to the bushing 12, the fan blade 2 swings around the bushing 12 to open and retract. In this way, the swing of the fan blade is flexible, and the fan blade can be installed simply and firmly.
