Abstract

The utility model provides a curtain switch is fixed with rope pressure switch at its inner corner, and the middle part is passed through frame bottom plate and apron fixed motor, variable speed drive wheel and rope winding wheel, and the aperture of one side and lower angle is as power input and control switch's pin hole in the shell, and the curtain switch rope of area presser presses switch, fixed pulley to the rope winding wheel through the rope. When the curtain switch is installed, the opening and closing of the curtain can be easily and freely controlled by pressing the switch no matter how high and wide the window is above the ground. The curtain opening and closing device is convenient and labor-saving to use, attractive in appearance and wide in application range.

Description

Curtain opening/closing device

The utility model relates to drawing back of a kind of curtain and closing device, especially a kind of curtain openers.

Development along with society, making rapid progress of reform and opening-up, people more and more are particular about and pay attention to the decoration of windows such as family, market, hotel, cinema and meeting room, the present curtain of selling on the market, be mainly the door curtain made of cloth and shutter, and shutter can only use on narrower window, is not suitable for big width such as modern meeting room, hotel, movie theatre, the use of liftoff higher window; Though pull the window that moving cloth curtain is applicable to that width is bigger, just need manually draw, effort, hard, and if rope has broken away from fixed pulley and then spurred more difficult; Though some automatic switch window shade arrangements are also arranged now, because work is unreliable, fault rate is high, and design is very unreasonable etc. former thereby do not applied.

It is little, both artistic and practical that the purpose of this utility model provides a kind of volume, can solve the problems such as Curtain switch inconvenience of overhead higher window and broad window, and curtain openers easy to use.

The utility model by shell, rope compress switch, frame bottom plate, cover plate, speed change drive, motor and bull wheel etc. form.

Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model user mode figure.

External form of the present utility model is square, in shell (1) one on the angle be fixed with rope compress switch (3), two root window curtain switch ropes (11) of son with pressure (2) penetrate in the shell on top outside shell (1), through rope compress switch (3) vertically move two fixed pulleys (7) of shell (1) inferior horn to bull wheel (6), the shell internal upper part is fixed a motor (4), be connected mutually the gear wheel with gear wheel (10) by gear (10) again with bull wheel (6) interlock of its underpart, on the two sides of motor (4) with bull wheel (6), with wheel shaft fixed base base plate (9) and support cover plate (8), a side and the inferior horn of shell (1) have respectively an aperture, as the fairlead of power supply input and gauge tap (5).

Rope compress switch (3) be by a wireless band switch and the flute profile iron sheet that two sizes of two fixed pulleys, a movable pulley are nested is housed consists of. Wireless band switch moves about being, be fixed on the bigger flute profile iron sheet, this piece iron sheet has a rectangular hole facing to the handle place of band switch, allows in the handle of band switch stretches into, and the size of this slot can make the handle activity of band switch freely get final product. Little flute profile iron sheet inside also has a hole facing to this place, and the size in this hole is the same with the handle of band switch, can be inserted in to get final product, and makes the handle of band switch follow little flute profile iron sheet and moves. Rope compresses switch and mainly is on the curtain switch rope near the window two the fixed pulley in the middle of having moved drives band switch and changes the sense of current when pressing son to compress switch by rope, also just can reversing rotation of motors, thus driven the curtain Push And Release.

Gear wheel (10) is by small one and large one two overlapping forming of gear. Bull wheel (6) then is the identical flute profiles wheel of two specifications and the union body of a gear.

During use, on two angles, load onto corresponding L shaped angle bar respectively about above the window, the overhanging end of two angle bar towards, there are two equidistant curtain stringing holes their corresponding sections, below.After several annulus of two door curtain made of cloth tops pass with the curtain stringing, the two ends of rope are separately fixed at two holes of angle bar below, left side angle bar upper fixed a flute profile fixed pulley, this is used to make Curtain switch rope travel direction opposite, two fixed pulleys in the angle bar top lowering on the right, the distance of these two fixed pulleys equals the diameter of the fixed pulley on the left side, the Curtain switch rope is by past sagging behind these two fixed pulleys, in the curtain openers on or below the feeding window limit, like this, no matter how high window is, how wide, only need Push switch, just can control the Push And Release of curtain easily.

This curtain openers is not only convenient and strength-saving, and shell can correspondingly do very attractive in appearancely, is contained on the window limits such as meeting room, hotel, market and also can plays beautification function.
