Abstract

The utility model discloses a wireless electric curtain which comprises a guide rail, a towing trolley and curtain hooks; wherein the towing trolley is constrained by the guide rail and moves along the guide rail; the curtain also comprises a pulley which is constrained by the guide rail; the towing trolley drives the pulley to move along the guide rail by a pushing handle; the curtain hooks are arranged on the pulley, and the top end of the curtain hooks is provided with a magnet; and the bottom plate of the towing trolley is provided with a controlled component under the action of the magnet. By adding the pulley, the towing trolley pushes the pulley to move along the guide rail by the pushing handle which is controlled by a self-suction valve; when power is lost, the pulley is separated from the towing trolley and slides freely along the guide rail, and when the curtain is hung or overloaded, the pulley breaks away from the towing trolley, so the protection function works.

Description

The Ropeless electric curtain

Technical field

The utility model relates to a kind of Ropeless electric curtain.

Background technology

Now, the plurality of advantages of electrically driven curtain is known well by people, hotel, school, family decoration curtain adopt electrically driven curtain mostly, electrically driven curtain generally is divided into two kinds, swing cover type and perpendicular open type, but no matter which kind of mode, curtain is in use, may be hooked on other object, curtain is in switching process, and existing is not that Curtain suspension device is bad, exactly drive motors is burnt out, perhaps damage the phenomenon of track, and generally speaking, if prominent the chance when having a power failure, because the transmission mechanism complexity, stressed bigger, curtain can't spur.

The utility model content

Easily folding when the utility model technical issues that need to address provide a kind of nothing electricity, the Ropeless electric curtain that can protect automatically when curtain tangles.

For addressing the above problem, technical solution adopted in the utility model is: a kind of Ropeless electric curtain, comprise guide rail, trailer wagon, tieback, trailer wagon is retrained by guide rail, along guide rail movement, also comprise coaster, this coaster is retrained by guide rail, and trailer wagon drives coaster along guide rail movement by pushing hands, on the described coaster tieback is installed, the top of tieback is provided with magnet, and the base plate of trailer wagon is provided with the controlled member that is subjected to the magnet effect.

Described controlled member can be a kind of in tongue tube, the Hall element.

The casing that described coaster comprises housing, has the push pedal of groove slideway, has top board and projection, casing is positioned at housing, can slide up and down along inner walls, the vertical plates on both sides that housing is passed in push pedal is positioned at casing bottom, and the groove slideway in the push pedal matches with the projection of casing, and the magnet on tieback top is positioned at the bottom of casing inside ceiling panel, next-door neighbour's top board, its position is corresponding with the controlled member on the trailer wagon base plate, is loaded on spring on tieback, and spring is between casing and magnet.

Be provided with self-priming valve in the described trailer wagon; self-priming valve is connected the employing beneficial effect that technique scheme produced and is with pushing hands: this is novel by increasing coaster; and promote coaster along guide rail movement by pushing hands by trailer wagon; pushing hands is controlled by self-priming valve, and when not having electricity, coaster separates with trailer wagon; can free slide along guide rail; curtain is tangled or when transshipping, coaster and trailer wagon break away from, and play a protective role.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As shown in Figure 1, 2, the utility model comprises guide rail 1, trailer wagon 3, tieback 7, coaster 5, wherein be provided with dry-reed tube switch in the trailer wagon 3, constitute induction installation with the magnet 4 that is provided with in the coaster 5, be provided with self-priming valve 11 in the trailer wagon 3, pushing hands 10 is installed on the self-priming valve 11, and self-priming valve 11 drives pushing hands 10 by leverage and does circular motion, and its movement locus is perpendicular to curtain rail 1.Trailer wagon 3 is subjected to guide rail 1 constraint, move along guide rail 1, coaster 5 comprises housing, push pedal 8 with groove slideway, casing 9 with top board and projection, casing 9 is positioned at housing, can slide up and down along inner walls, push pedal 8 is passed the vertical plates on both sides of housing and is positioned at casing 9 bottoms, groove slideway in the push pedal 8 matches with the projection of casing 9, magnet 4 is positioned at the bottom of casing 9 inside ceiling panels, next-door neighbour's top board, its position is corresponding with the tongue tube on trailer wagon 3 base plates, on tieback 7, be loaded on spring 6, spring 6 is between casing 9 and magnet 4, and coaster 5 is retrained by guide rail, and trailer wagon 3 drives coaster 5 along guide rail movement by pushing hands 8, the bossing of above-mentioned casing 9 can adopt roller, move in the groove slideway easilier, the tongue tube on above-mentioned trailer wagon 3 base plates can also adopt other controlled member 2, such as: Hall element.

Operation principle:

After the energising; the motor of electrically driven curtain controller control trailer wagon gets; dolly is along guide rail movement; when moving of car arrives the coaster top; the tongue tube adhesive; the action of control self-priming valve; the pushing hands action that is connected with self-priming valve; pushing hands drives coaster and follows the trailer wagon motion; in order to increase stability; reduce the active force of pushing hands simultaneously; pushing hands promotes supratrochlear push pedal; the push pedal campaign is with casing jack-up, and roof box contacts with the trailer wagon base plate, and trailer wagon drives the coaster motion; when curtain is tangled; tieback is stressed, the compression spring, and the magnet that is positioned at the tieback top is towards the direction motion away from top board; thereby make the sphere of action of the tongue tube disengaging magnet on the trailer wagon; tongue tube disconnects, and electrically driven curtain controller control self-priming valve is regained pushing hands, and trailer wagon and coaster break away from; protected the mechanism of trailer wagon and electrically driven curtain; when running into the situation of power failure, self-priming valve is failure to actuate, and the original state of coupled pushing hands is a retracted state; coaster is not retrained by pushing hands; can be along the guide rail freely-movable, and frictional force is less, is easy to curtain open/close.Trailer wagon motion puts in place after (curtain is fully withdrawn or closes), and touching limit switch, trailer wagon are stopped by curtain controller control dead electricity, and it stops the control technology that mode can adopt existing electrically driven curtain fully.
