Abstract

The utility model discloses an anti-falling safety device for a ceiling fan and a ceiling lamp, which is composed of an upper hanging assembly, the main body of the device, and an adjustment assembly. The outer cylinder body of the main body of the device is fixedly connected with an end cover. An inner cylinder body is installed on one side of the outer cylinder body and can move in the axial direction. One end of the inner cylinder body is connected with the upper hanging assembly through cables. An insulated lining is fixed in the inner cylinder body. One end of the contact head of a bar is fixed in the center of the insulated lining. The other end of the contact head of the bar extends into an insulated spring seat and is sheathed with a spring. A contact head is fixedly installed in the insulated spring seat and forms a normally closed contact head with the contact head of the bar. The utility model can lead the ceiling fan and the ceiling lamp not to fall down to cut off a power supply simultaneously when supporting members suddenly fail, and has the anti-falling function and the safety function.

Description

The anti-fall protective device of ceiling fan ceiling lamp

The utility model relates to the anti-fall protective device of a kind of ceiling fan ceiling lamp.

At present the employed ceiling fan ceiling lamp of people (revolving light) is directly to hang on its supporting member, causes the ceiling fan ceiling lamp hurting people or smashing objects of falling easily because of last a very long time being subjected to change, shake, turn round the generation fatigue rupture of moving.

The purpose of this utility model is to provide a kind of ceiling fan ceiling lamp that prevents to fall under the fortuitous event of its supporting member catastrophic failure, and can control the anti-fall protective device of ceiling fan ceiling lamp of electric wiring break-make simultaneously.

The utility model is achieved in that its last hanging component by a tightening self, and the apparatus main body of a control electric loop break-make and the adjustment assembly of fine setting working sensitivity are formed.The metal shell of apparatus main body is made up of outer cylinder body and the end cap affixed with it, end cap passes through joint, hawser connects with the adjustment assembly, inner barrel is installed in the side of outer cylinder body and can moves axially, the one end links by hawser and last hanging component, one insulation lining is fixedly mounted in the inner barrel, bar contact one end with excellent conductive performance that is connecting lead is fixed on insulation lining center, the other end stretches in the insulated spring seat and suit the bar contact is imposed the spring that gives tight power, the contact with excellent conductive performance that is connecting lead is fixed in the insulated spring seat and forms normally closed interlock with the bar contact, when its gravitate, make normally closed interlock separately, cut off working power automatically.

Adjusting assembly is made up of an end and hawser affixed lower contact and adjustment nut, adjusting nut becomes to be threaded with lower contact, but and precession or back-out, thereby between hawser degree of tightness and electric normally closed interlock the contact stress adjust, make normally closed interlock be in perfect condition.

The utility model is an aiding support, owing to adopt above-mentioned structure, thereby work as ceiling fan ceiling lamp under the situation of its supporting member catastrophic failure, and its unlikely falling can be made, and the electric wiring break-make can be controlled simultaneously.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Last hanging component suspension ring [14] are fixedly connected by screw thread and top connection [15] and lock with nut [16], hawser [4] one ends and top connection [15] are affixed, the inner barrel of the other end and apparatus main body [3] is affixed, the outer cylinder body of apparatus main body [1] is affixed with end cap [2], inner barrel [3] is installed in the side of outer cylinder body [1] and can moves axially, one insulation lining [5] is fixedly mounted in the inner barrel [3], bar contact [6] one ends that connecting lead [7] are fixed on insulation lining [5] center, the other end stretches in the insulated spring seat [8] and suit spring [9] and packing ring [17], the contact that is connecting lead [7] is fixed in the insulated spring seat [8] and forms normally closed interlock with bar contact [6], end cap [2] is by attachment screw [18], joint [11], hawser [4] is connected with lower contact [12] in adjusting assembly, lower contact [12] is connected by screw thread with adjustment nut [13], during use, suspension ring [14] are fixed on (as ceiling) on the supporter, apparatus main body is packed in the suspension rod of ceiling fan ceiling lamp, two ends lead [7] is serially connected in the power line, the adjustment assembly is packed in the ceiling fan ceiling lamp head axle, adjustment nut [13] is stuck on the step of head axle, control the degree of tightness of hawser [4] and the contact stress between normally closed interlock by the screwing length of adjusting lower contact [12] and adjustment nut [13], thereby improve working sensitivity of the present utility model.When the own supporting member of ceiling fan ceiling lamp during because of fatigue rupture, this utility model is when weight tenesmus displacement, and the automatic disconnection under the gravity effect of its normally closed interlock quits work the ceiling fan ceiling lamp dead electricity, stop the continuation tenesmus of weight on the other hand again, play anti-fall security personnel's effect.

The utility model also can be applicable among the anti-fall security personnel of other hanging object.
