Description

The distance type device for draw-back curtain

Technical field:

The utility model relates to a kind of distance type device for draw-back curtain.

Background technology:

The tradition curtain generally by the curtain rod arm that is installed in window top, curtain and the curtain rope that is used to spur Curtain switch constitute.A kind of form is that several annulus are installed on the circular cross bar that is provided with on the curtain rod arm, curtain is fixed on the annulus manual switch curtain again; Another kind of form is, two ropes of pulling back are set in curtain rod arm, then curtain is connected with pulling back to restrict, and controls Curtain switch by the curtain rope.The switch of above-mentioned two kinds of structure curtain all is by finishing manually, and the hand switch curtain promptly is awkward, and influences the aesthetic appearance of curtain again.

For this reason, " the distance type pelmet " of No. 2152467 bulletins of Chinese patent is exactly a solution that proposes at the problems referred to above.This pelmet comprises motor and by the transmission mechanism of driven by motor, and optical signal receiver constitutes, and transmission mechanism by screw mandrel and fixedly the supporting of screw mandrel form.Though this distance type pelmet can be realized the automatic switch curtain, but, because it has adopted the transmission mechanism of structure relative complex, cause the raising of this pelmet cost of manufacture, because of needing frequent switch, uses by curtain simultaneously, transmission mechanism is vulnerable to wearing and tearing in the frequent course of work, cause shorten its service life; In addition, the disclosed photelectric receiver of this patent only adopts bridge rectifier parts that input voltage is carried out rectification, so this receiver is difficult to guarantee that curtain normally uses under operating modes such as external line under-voltage or superpressure.

In addition, " a kind of electric remote-controlled curtain suspension machine " of No. 2276067 bulletins of Chinese patent also is a solution that is proposed at manual control switch's curtain.This window curtain driving mechanism is made up of structure guide rail, interchange reversible line motor, control circuit and inferior ultrasonic air bag.Though this kind window curtain driving mechanism adopts the structure of gearless driving, but, because this window curtain driving mechanism utilizes linear electric motors reciprocating mode on guide rail to finish Curtain switch, and linear electric motors itself have certain weight, add the weight of parts such as guide rail, can bring many inconvenience directly for the installation of curtain rod arm, make this window curtain driving mechanism have higher cost of manufacture because of adding parts such as inferior ultrasonic air bag is arranged simultaneously.

Summary of the invention:

Task of the present utility model provides a kind of distance type device for draw-back curtain of mode to simplify its structure and to prolong its service life that utilizes the direct switch curtain of motor.

For finishing above-mentioned task, the distance type device for draw-back curtain that the utility model proposed comprises the housing that is installed on the curtain rod arm and is arranged on the interior motor of this housing, and the Control Component that is used to control described motor operating state, directive wheel directly is installed on the output shaft of described motor.

Described Control Component comprises the transformation rectifier stack that input is electrically connected with supply network, and the output of this transformation rectifier stack is electrically connected with switch block and time-delay assembly, and is used to control the remote controller that described switch block is realized opening and closing movement.

The doube bridge formula rectification part that described transformation rectifier stack comprises transformer and is electrically connected with the output of this transformation, the output of one of them bridge rectifier parts directly is connected with relay, and another bridge rectifier parts are connected with the time-delay assembly by relay.

Described directive wheel has radial groove, the limiting component of the position of the rope that is used to limit and spur casement is installed in the front portion of directive wheel, this limiting component has a central region to the plate away from the direction projection of directive wheel, two sides of this plate are provided with the groove that the rope that allows the pulling curtain passes, and are separately installed with a position-limited wheel in the both sides of plate protruding part.

The distance type device for draw-back curtain that the utility model proposed adopts motor directly to control the curtain rope to realize the curtain full-automatic switch, so, it is little and in light weight that this device has a volume, and characteristics such as easy for installation, and because of this kind mode can be omitted many drive disk assemblies, in its running, be power saving, noiselessness again; Because of Control Component adopts doube bridge formula rectification part, can realize the two protections of under-voltage, superpressure simultaneously.

Description of drawings:

Accompanying drawing 1 is that the surface structure of the embodiment of distance type device for draw-back curtain that proposes of the utility model launches schematic diagram;

Accompanying drawing 2 is circuit theory schematic diagrames of Control Component among Fig. 1.

The specific embodiment:

Referring to Fig. 1 and Fig. 2, these two accompanying drawings provide the overall appearance structure of the embodiment of distance type device for draw-back curtain that the utility model proposes.This device comprises housing 1 that can be installed in curtain rod arm one end and the motor 2 that is arranged in the described housing 1, and the Control Component 3 of control motor movement state.The directive wheel 4 of band radial groove 41 directly is installed on the output shaft 21 of motor 2, at directive wheel 4 and towards the front portion of curtain direction limiting component 5 is installed, this limiting component 5 is prismatic plates, it dwindles gradually towards the curtain direction, and the middle part is provided with a protuberance 52 forward, be respectively arranged with position-limited wheel 53 in the both sides of protuberance 52, and be respectively arranged with groove 51 in the both sides of limiting component 5.Annular curtain rope passes through position-limited wheel 53 and groove 51 successively, and groove 41.When motor rotates, can drive directive wheel 4 and rotate, thereby the rope of pulling casement is also along with rotation, so that casement is finished opening or closing of task.

Fig. 2 provides the concrete structure of the circuit theory of 3 one embodiment of Control Component.Control Component 3 comprises transformation rectifier stack and the remote controller (because of remote controller belongs to prior art, not providing concrete structure among the figure) that is made of transformer 31 and bridge rectifier parts 32 and 33, and the switch block K that is subjected to remote controller control.The input of transformer 31 is electrically connected with supply network, output is electrically connected with bridge rectifier parts 32 and bridge rectifier parts 33 respectively, wherein, the output of bridge rectifier parts 32 is connected with relay J 1, the output of bridge rectifier parts 33 and switch block K be connected with the time-delay assembly through relay J 2.

Described time-delay assembly is to be main part with 555 integration module IC, 7 jiaos of integration module IC are connected with the emitter stage of triode G with diode D1 through resistance R 1,6 jiaos and 2 jiaos are provided with resistance R 2 and capacitor C, and the base stage of triode G is connected with motor 2 through full-bridge type rectification part 34.
