Embodiment Construction
[0024] see Figure 1-Figure 3 , The present invention is a fan lamp (hereinafter referred to as fan lamp) equipped with an automatic power-off device for accidental fall.
[0025] The fan light of the present invention includes a hanging part 1 provided with a hanging rod 11 and a rotating part 2 provided with a hanging head 21; the hanging rod 11 is inserted into the hanging head 21 and connected by fasteners, so that the hanging part 1 is connected to the rotating part 2.
[0026] Such as fastener can be latch 22, and latch 22 runs through suspender 11 and suspender 21, and latch 22 is connected with suspender 11; Fastener can also comprise safety pin 23, and safety pin 2 inserts latch 22 from one end of latch 22 Or through the bolt 22, so as to ensure that the bolt 22 will not be pulled out from the boom 11 and the hanger 21, thereby ensuring reliability.
[0027] Here, the hoisting part 1 is generally used for hoisting the fan lamp and the like on a desired position (suc...

The invention relates to the field of fan lamps, in particular to a fan lamp provided with an accidental falling automatic power-off device. The fan lamp comprises a hoisting part with a hanging rod, and a rotating part provided with a hanging head. The hanging rod is inserted in the hanging head and fastened through a fastener. The fastener comprises bolts penetrating the hanging rod and the hanging head. The fan lamp provided with the accidental falling automatic power-off device further comprises the automatic power-off device. The automatic power-off device at least comprises a switch gland, a switch support and a switch. The switch is a travel switch and is fixedly arranged on the switch support. The switch gland and the hanging head are fixedly connected. The switch support and the hanging rod are fixedly connected. A contact of the switch is pressed by the switch gland. The stroke critical value of the switch is 25%-75% of the diameter of the bolts. In the fan lamp, when the falling distance H exceeds the stroke critical value of the switch, a circuit between a control panel and the rotating part is disconnected through the switch, the rotating part is powered off and stops rotating or cannot be started, and therefore a safety protection function is achieved.
Description
technical field [0001] The invention relates to the field of fan lamps, in particular to a fan lamp equipped with an automatic power-off device for accidental fall. Background technique [0002] For the convenience of transportation and installation, all kinds of fan lamps (such as: ceiling fan lamps) generally have a split structure, that is, the hoisting part and the rotating part are separated. At the place of use, the lifting part and the rotating part are connected by fasteners. [0003] At present, all kinds of fan lamps are generally hoisted on the roof, and the fasteners connecting the hoisting part and the rotating part cannot be directly observed. When the fan lamp has been used for a long time, the fasteners are aging, or the fastener itself is defective, resulting in poor strength of the fastener, the fan lamp may fall and cause personal injury. Contents of the invention [0004] In order to solve the above problems, the object of the present invention is to ...
