Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] see Figure 1-4 , a retractable and fall-proof chandelier fan, comprising a ceiling 1, the bottom of the ceiling 1 is provided with through grooves on both sides of the power shaft 2, the through groove of the ceiling 1 is provided with a semicircular groove near the side of the power shaft 2, and a limit rod 5 The upper end close to the power shaft 2 side is fixedly connected with a bump, the radius of the bump coincides with the radius of the semi-cir...

The invention relates to the field of ceilings, and discloses a retractable and anti-falling ceiling lamp fan. A power shaft is slidingly connected with the middle portion of a ceiling, a first bearing is fixedly connected with the upper end of the curved surface of the power shaft, fixing rings are fixedly connected with the upper and lower ends of the curved surface of the first bearing, limiting rods are movably connected with the upper and lower sides of the interiors of the fixing rings, a second bearing is slidingly connected with the middle portion of the curved surface of the power shaft, two sides of the front face of the second bearing are rotatably connected with first rotating rods, and the lower ends of two sides of the power shaft are rotatably connected with springs. If fan blade parts or the power shaft is disconnected to cause falling of a device, the power shaft falls to drive the fixing rings to press the limiting rods to rotate and enable convex blocks of the limiting rods to be clamped with semicircular grooves, thus the limiting rods do not rotate any more, the fixing rings are prevented from continuously falling through the transverse portions at the lower ends of the limiting rods, if the limiting rods also break down, the first bearing and the fixing rings can be blocked by the upper end of the second bearing, and the second bearing pulls air cylinders and the springs through the first rotating rods, so that the power shaft is prevented from falling, and the purpose of ceiling fan falling protection is achieved.
Description
technical field [0001] The invention relates to the technical field of suspended ceilings, in particular to a retractable and anti-falling ceiling fan. Background technique [0002] With the vigorous development of the field of architectural decoration, more and more indoor installations have suspended ceilings. Ceiling fans are also a very common type of ceiling that combines decoration and fan functions, but the blades of ceiling fans are exposed for a long time It is easy to accumulate dust outside, and most fans installed in the ceiling have no fall protection, which poses a safety hazard. [0003] When the ceiling fan plays the role of a fan, it also needs to take into account the task of decoration, and the fan blades of most ceiling fans are often exposed to the air. Even if they are retracted into the ceiling, they are retracted horizontally, and the upper end is easy to accumulate dust. Fanning again will make the room full of dust, and some ceiling fans are easy t...
