Description

Improved structure of ceiling fan lamp

Technical Field

The utility model belongs to the technical field of the fan lamp technique and specifically relates to a ceiling fan lamp improves structure.

Background

The existing ceiling fan lamp structurally comprises a fan part and a lamp part, wherein the fan part is arranged at the upper part of the lamp part and comprises a motor component, blades (also called as fan blades), a chassis and a blade extending and resetting mechanism, the blades are arranged on the periphery of the upper surface of the chassis through the blade extending and resetting mechanism, and the chassis is driven by the motor component; when the ceiling fan stops working, the blades are retracted to the edge of the upper surface of the chassis under the action of the extending force of the blades and the resetting force of the resetting mechanism; this kind of conventional ceiling fan lamp is also called as a ceiling fan lamp with hidden blades (i.e. fan blades), namely: the blades extend and retract back into the chassis, and after the blades are retracted, the blades are not visible from the bottom of the ceiling fan light.

However, the ceiling fan lamp with hidden blades still has the following disadvantages: (1) when the blade is collected, namely: when the blades are in a retreated (stored) state, the blades are encircled into a circumference shape on the edge of the upper surface of the chassis and are limited by the circumference of the outer edge of the chassis, when the number of the blades is large or the length of the blades is large, the adjacent blades are overlapped end to end, therefore, in order to avoid mutual collision (offset) between the overlapped blades in the retreating process, the blades are made into a high-low two section shape or are made into an upward extending shape from low to high, the process difficulty is high, and when the blades are retreated (stored), the connecting positions of the high and low of the blades are easy to collide with the adjacent blades, the blades are extended from low to high, the overall height is large, particularly, the bottom of the ceiling fan lamp also comprises a lamp part, and therefore, the ceiling fan lamp with the excessively large height is not suitable for being used in rooms with lower floors (such as common commercial buildings). (2) When the blade extends or retracts, the blade is realized through the rotation of the rotating shaft at the root of the blade, namely, the rotation of the whole blade is realized by taking the rotating shaft as a fulcrum, the blade is easy to deviate (such as droop) due to installation difference, and the blade is easy to collide with the adjacent blade in a retraction state, so that the requirement on the blade installation process is very high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of above-mentioned prior art existence, and provide a ceiling fan lamp improvement structure that height is little, blade mounting process requires lowly.

(2) Secondly, the linear guide rail ensures that the blades extend and retract (contract) along the radius direction of the rotating disc (or the radius direction of the fixed shaft), and the linear extending and retracting of the blades are relatively stable and smooth, unlike the traditional extending and retracting actions of the blades in a shaft rotating mode.

(3) In addition, when the blade stretches out, the blade drives the guide post and removes in spacing logical inslot, and the guide post also removes in the guiding hole, promptly: the guide post can push the synchronous disc to rotate, and then the synchronous disc enables all blades to keep synchronous in movement, so that the blades are more stably unfolded; after the motor stops, the piece that resets drives the synchronous dish antiport, and the synchronous dish promotes the guide post through the guiding hole and removes in spacing logical inslot to realize that the blade is synchronous to be returned (indentation rolling disc), the blade is hidden promptly.

(4) The reset piece is a pot ring spring, the pot ring spring is small in size, easy to install, easy to obtain and low in cost, the length of the guide hole limits the elastic range of the pot ring spring, and transition stretching or compression failure of the pot ring spring is avoided.
