Abstract

The utility model provides a mechanism for opening and closing window curtains or curtains, taking a direct-current power supply as the power supply, and mainly comprising a direct-current motor, a speed-changing and power-driving mechanism, a curtain box, a running mechanism and an electric controlling device comprising a controlling switch for a power supply, a stroke converting switch and a diode type positive-reverse circuit. The utility model has the advantages of simple structure, low cost, easy convenient installation and operation, etc. overcoming the shortages that the present electric curtain device which adopts mains supply as the power supply has complicated structure and high cost, and is susceptible to the influence of factors of power failure, etc. The utility model can be widely used for the opening and the closing of indoor window curtains, stage curtains and the curtains of television cabinets.

Description

Electric curtain machine

The utility model relates to a kind of electric device that opens and closes curtain or curtain, is mainly used in the keying of indoor curtain, stage curtain, also can be used for miniature curtains such as cabinet for television set unlatching, close.

The most direct use civil power of the electric controller for curtain of Chu Shouing in the market, thus the influence of factor such as usually had a power failure, but also exist version complexity, cost height, shortcoming such as should not promote.

It is engine with the direct current generator that the purpose of this utility model is to provide a kind of, and the foolproof electric controller for curtain of structure is to overcome the existing weak point of above-mentioned window curtain driving mechanism.

The utility model is mainly by direct current generator, speed change and power transmitting mechanism, pelmet, walking mechanism, and composition such as electric controller.Two fixed pulleys that are with backguy are fixed in the two ends of pelmet; Direct current generator is loaded on the above-mentioned pulley outside, and its change pulley and this fixed pulley are fixed in same axle; Left and right slide bar or guide rail are loaded on the below of pull-down line, and the left and right sides cord of band suspension ring hangs on this two slide bar or the guide rail; The one stroke change-over switch is loaded on the pelmet plate of backguy middle part; The ring folder of the left and right sides, location cord is housed in the backguy and promotes the left and right sides shifting block that the stroke change-over switch is changed.Electronic control section mainly constitutes by DC current and gauge tap thereof with by the forward and reverse circuit of motor that stroke change-over switch and diode are formed.The fixed juncture of one double-point double-throw switch is connected to the two ends of dc source, and two group selection contacts link to each other with the fixed juncture of DPDT type stroke change-over switch respectively; The two ends of direct current generator are connected to respectively by two, the parallel circuit that the diode of reversal connection is each other formed, and the other end of above-mentioned four diodes is connected to respectively on the corresponding selection contact of above-mentioned stroke change-over switch.Power control part divides and forward and reverse circuit part can split, and connects with connector therebetween.

The utlity model has simple in structurely, cost is low, and is easy to use, advantages such as wide application.

Description of drawings: accompanying drawing 1 is the utility model structural representation

Accompanying drawing 2 is the electrical schematic diagram of the electronic control section of the utility model.

Below in conjunction with accompanying drawing the utility model is described further.The fixed pulley 1 and 8 that is with backguy 3 is loaded on the two ends of pelmet, DC micromotor 11(M respectively) be loaded on the outside of fixed pulley 8, and between the belt pulley 12 of coaxial change pulley 9 of fixed pulley 8 and motor 11 belt 10 is housed; Two slide bars are loaded on the below of the last downward cabling of backguy 3 about 2,5 minutes, several the suspension ring 16 that are loaded on the cord upper end hang on left and

right sides cord

18,13 on the left and right sides slide bar 2,5; One DPDT type slip change-over switch 15 is loaded on the pelmet base plate 4 of backguy middle part; Be equipped with in the backguy 3 to collapse and strain at spring 7, and be fixed with left and right sides cord locating ring folder 6 and promote the left and right

sides shifting block

17,14 of slip change-over switch 15 actions.In electronic control circuit, DPDT formula power control switch K ₁Two fixed junctures be connected to the two ends of dc source (or battery pack), K switch ₁Selection contact K _1-1, K _{1-2 '}And K ₁-1 ', K _1-2Be connected to DPDT formula slip change-over switch K respectively ₂(15) on fixed juncture b, a; The two ends of direct current generator M are connected to the diode D by reversal connection each other respectively ₁, D ₃And D ₂, D ₄The parallel circuit of forming, diode D ₁, D ₃, D ₂, D ₄The another pin be connected to slip change-over switch K respectively ₂(15) select contact K _2-1, K _2-2, K _{2-1 '}, K _{2-2 '}On, power control part divides and forward and reverse circuit part can divide and is arranged, and uses connector CT therebetween ₁, CT ₂Connect.Power switch K is set ₁The selection contact be in K _1-1, K _1-2, slip change-over switch K ₂The selection contact be in K _2-1, K _2-2State, diode D ₁, D ₂End, motor is not worked, and this moment, curtain was a closed condition.Toggle switch K ₁To K _{1-1 '}, K _{1-2 '}, the time diode D ₁, D ₂Conducting, motor M is just changeed, and its belt pulley 10 drives change pulleys 9 and fixed pulley 8,1 rotates simultaneously, and backguy 3 drive left and right sides cords are walked to the both sides from the centre, when cord is opened to maximum, is fixed on right shifting block 14 in the backguy 3 and promptly promotes slide switch K2 and be converted to K _{2-1 '}, K _{2-2 '}Select contact, at this moment the diode D in the circuit ₃, D ₄Be in cut-off state and motor M (11) is quit work.When lifting gauge tap K1 once more, make it be in K _1-1, K _1-2The time, diode D ₃, D ₄Conducting, and for motor M for reversing the current, make the motor M counter-rotating, thereby make backguy 3 that cord is pulled to central authorities from both sides, when left and

right sides curtain

18,13 closed up, left shifting block 17 promoted slip change-over switch K2(15) be converted to K again _2-1, K _2-2The position, this moment diode D ₁, D ₂End, motor M (11) stall when lifting K1 once more, will be drawn back cord once more.
