Summary of the invention

Technical problem to be solved by this invention is to provide a kind of cord tightness detector that is used for electric clothes hanger that is more suitable for practical application at above-mentioned prior art present situation, it can make clothes-horse occur providing signal to control device under the fortuitous event, motor is quit work, thereby make electric clothes hanger more safe and reliable.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this is used for the cord tightness detector of electric clothes hanger, includes support and the directive wheel that is fixed on the support, it is characterized in that also including:

One detection wheel that is set up in parallel along rope direction and directive wheel, being arranged on the support versatilely as the mode that lateral moves relative to rope, and by the trend that keeps under the effect of an extension spring interlacing with directive wheel, and rope is oblique passing between directive wheel and the detection wheel tangently;

And one can perception the sense switch that moves of detection wheel.

Wherein, the sense switch that energy perception detection wheel moves can adopt existing various technology, for ease of realizing, make device simpler, described sense switch can be one to be arranged on contact on the support moving switch that declines, and the end of its contact is resisted against in the rotating shaft of detection wheel directly or indirectly, like this, moving of detection wheel rotating shaft just can be stirred the contact of microswitch, thereby provides signal by microswitch, controls the running of motor then.

Described extension spring first end is fixed on the roller end of described detection wheel, and the relative support of second end is fixed.

For making moving of detection wheel more steady, described extension spring can have two, and their first end is separately fixed at the rotating shaft two ends of described detection wheel, like this, the two ends up and down of detection wheel rotating shaft are all held by extension spring respectively, and stable moves as lateral relative to rope.

When reality was used, rope intersects walked around directive wheel and detection wheel, when rope stretch, rope is stirred detection wheel moves its rotating shaft laterally, extension spring also is tightened up, the contact of microswitch in the raw, the inner conducting of microswitch and make the motor operate as normal; And when rope was in slack and undisciplined state, the rotating shaft of detection wheel was promptly moved to the inside because of the effect of extension spring, and thruster is moving forward with regard to the rotating shaft of tested measuring wheel for the contact of microswitch, and microswitch inside is open close, thereby motor is quit work.

Compared with prior art, the invention has the advantages that: by the cooperation of directive wheel and detection wheel, just can check the degree of tightness state of rope from being displaced sideways of detection wheel, and being displaced sideways of detection wheel also given signal of control device by sense switch, the work of control motor, like this, in case clothes-horse can't descend smoothly because of accident stops, rope promptly is in the state of loosening, detection wheel just can be given out-of-work signal of control device by sense switch, motor is shut down, thereby make electric clothes hanger as safe as a house reliable when reality is used; And, sense switch is designed to a contact moving switch that declines, make cooperating of its contact and detection wheel rotating shaft, what make detection wheel easily mobilely provides out-of-work control signal, and structure is very simple, is easy to realize; Structure of the present invention is very simple, and running is sensitive, is very suitable for practical application.
