Abstract
The utility model relates to a household curtain device, in particular to a curtain opening and closing device. According to the principle of magnets that like poles repel and opposite poles attract, a slideway is arranged on a window, the end part of the slideway is provided with an electromagnet, the middle of the slideway is provided with a sliding electromagnet which drives a pulley to slide in the slideway, and the left and right movement of the electromagnet is realized by changing the magnetic poles of the middle electromagnet so as to realize opening and closing the curtain. The curtain opening and closing device has ingenious design, is simple to operate, has no noise and is both economic and environment-friendly.
Description
Technical field
The utility model relates to a kind of daily home-use window shade arrangement, especially a kind of curtain opening and closing device.
Background technology
Curtain opening and closing device in the market generally is to adopt the motor-driven pulley to slide in the slideway that is installed on the window, drives the curtain that hangs on the pulley conductor rope, realizes the effect that curtain opens and closes.The patent No. be CN201324126Y patent disclosure a kind of automatic curtain, curtain is installed on the conductor rope around pulley, one of them pulley is fixed in the rotating shaft of motor, motor is connected with control circuit.
The shortcoming of this device is: a motor must be installed in that the window slideway is other, and motor must bring noise, both uneconomical also not environmental protection when rotating.
The utility model content
The utility model is at the problems referred to above, proposed the curtain opening and closing device of a kind of not only economy but also environmental protection.
For realizing reaching the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of curtain opening and closing device comprises the roller that is installed in the slideway on the window and rolls on slideway, it is characterized in that: be hung with curtain below the roller, on the end of described slideway and the roller electromagnet be installed, electromagnet links to each other with on-off circuit.
The electromagnet of described slideway end is mounted in an end about it.
The electromagnet of described slideway end is mounted in its two ends, left and right sides.
Described electromagnet and on-off circuit all are can buy on the market.
The beneficial effect of this practical utility model:
1, owing to having adopted electromagnet, according to electromagnet, the principle that homopolar-repulsion, heteropole are inhaled mutually, the switching of practical curtain, electromagnet does not produce noise, environmental protection more when opening and closing.
2, owing to the device that has adopted middle electromagnet and pulley to link together, when having a power failure, electromagnet does not have magnetic, just as common curtain, can not occur drawing motionless problem because of motor stops curtain, and this structure economics material benefit.
Description of drawings:
Fig. 1: the structural representation of the utility model device
1,3,5 electromagnet, 2 slideways, 4 pulleys, 6 on-off circuits, 7 curtain
The specific embodiment
As shown in Figure 1: a kind of curtain opening and closing device, comprise slideway 2 that is installed on the window and the roller 4 that on slideway 2, rolls, it is characterized in that: the both ends of slideway 2 are installed with electromagnet (1,5), be hung with curtain 7 below the roller 4 that rolls in the slideway 2, be connected with an electromagnet 3 on the roller of end, electromagnet links to each other with on-off circuit 6.
When " opening " instruction in pressing on-off circuit 6, the electromagnet 1 of left part and middle electromagnet 3 opposite faces are homopolarity, electromagnet 3 phase right motions in the middle of left part electromagnet 1 promotes; Electromagnet 3 is that heteropole is inhaled mutually with right part electromagnet 5 opposite faces simultaneously, and electromagnet 3 drive pulleys move right in the middle of promoting under graviational interaction.
When instruct " pass " in pressing on-off circuit 6, electromagnet 5 magnetic poles of the electromagnet 1 of left part and right part are constant, middle electromagnet 3 magnetic poles become on the contrary, this moment, the electromagnet 5 of right part became homopolar-repulsion with middle electromagnet 3 opposite faces, the electromagnet 1 of left part becomes heteropole with middle electromagnet 3 opposite faces and inhales mutually, electromagnet 3 drives pulley to left movement in the middle of under the effect of magnetic force, realizes closing window.
In pressing on-off circuit 6 during halt instruction, no matter be to carry out to open indication or carry out to close indication this moment, all flick, the electromagnet 5 that is electromagnet 1, middle electromagnet 3 and the right part of left part all is in off-position, electromagnet does not all have magnetic, middle electromagnet 3 will stop on the slideway 2 and slide, and promptly curtain can be rested in any position of stopping wanted.
Generally, electromagnet is in off-position, can as usual spur curtain, realizes closing of curtain.
A kind of curtain opening and closing device, comprise slideway 2 that is installed on the window and the roller 4 that on slideway 2, rolls, it is characterized in that: the left part of slideway 2 is installed with electromagnet 1, be hung with curtain 7 below the roller 4 that rolls in the slideway 2, be connected with an electromagnet 3 on the roller of end, electromagnet links to each other with on-off circuit 6.
When " opening " instruction in pressing on-off circuit 6, the electromagnet 1 of left part and middle electromagnet 3 opposite faces are homopolarity, and electromagnet 3 phase right motions in the middle of left part electromagnet 1 promotes are opened curtain.
When instruct " pass " in pressing on-off circuit 6, electromagnet 1 magnetic pole of left part is constant, and middle electromagnet 3 magnetic poles become on the contrary, and the electromagnet 1 of left part becomes heteropole with middle electromagnet 3 opposite faces and inhales mutually, electromagnet 3 drives pulley to left movement in the middle of under the effect of magnetic force, closes curtain.
In pressing on-off circuit 6 during halt instruction, no matter be to carry out to open instruction or carry out to close instruction this moment, all flick, the electromagnet 1, the middle electromagnet 3 that are the left part all are in off-position, electromagnet does not all have magnetic, middle electromagnet 3 will stop on the slideway 2 and slide, and promptly curtain can be rested in any position of stopping wanted.
Generally, electromagnet is in off-position, can as usual spur curtain, realizes closing of curtain.
The utility model is not limited to appeal embodiment, and those of ordinary skill in the art can also make some conspicuous changes to above-mentioned enforcement, but these changes all should fall in the claimed scope of the utility model.
Claims (3)
1. curtain opening and closing device, comprise slideway (2) that is installed on the window and the roller (4) of going up rolling at slideway (2), it is characterized in that: be hung with curtain (7) below the roller (4), electromagnet (1,3,5) is installed on the end of described slideway (2) and the roller, and electromagnet links to each other with on-off circuit (6).
