Description

Curtain switch

The utility model relates to the device of draw-back curtain.

Existing curtain opening device, the class that cost is high exist complex structure, fault defect how, and its expensive price also makes it be difficult to generally use; The class that cost is low exists track easily to be bent by curtain and makes the curtain sag bent, influences attractive in appearancely, and wiring is very easily deviate from from race and caused awkward trouble.

The purpose of this utility model is, designs a kind of Curtain switch, has characteristics simple in structure, that cost is low, can keep track straight and do not make curtain sagging again, and dependable performance, easy to use.

The technical solution of the utility model is, it comprises left base and right base, through pulley bracket the stay cord assembly pulley has been installed respectively on described two bases, manual stay cord is housed between the described assembly pulley, its design feature is, through support the steel wire guide wheel has been installed on the base of a left side, through support tensioning shaft has been installed on the right base, between one end of this tensioning shaft and its support ratchet mechanism is arranged and its other end is the regular polygon termination, have on the tensioning shaft in order to penetrate the aperture of steel wire head, on the tensioning shaft support steady pin is housed, is fixedly connected on the steady pin and the other end is inserted in steel wire is rotated and tensioning with tensioning shaft as the steel wire pile warp steel wire guide wheel of curtain rail and one end.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings: accompanying drawing is a practical structures.Among this figure:

1-left side base, the right base of 2-, 3-assembly pulley, 4-assembly pulley, 5-steel wire guide wheel, 6-ratchet, 7-ratchet, the just polygon termination of 8-, 9-aperture, 10-tensioning shaft, the 11-pawl axis, 12-support, 13-support, the 14-steel wire, 15-stay cord, 16-face of pulley, the 17-support, 18-support, 19-steady pin.

By accompanying drawing as can be known, the utility model comprises left base (1) and right base (2), through support (17) (18) assembly pulley (3) (4) has been installed respectively on two bases (1) (2), manual stay cord (15) is housed between the described assembly pulley (3) (4), its design feature is, left base (1) is upper has installed steel wire guide wheel (5) through support (12), right base (2) is upper has installed tensioning shaft (10) through support (13), the ratchet mechanism (ratchet mechanism of prior art) that is made up of ratchet (7) and ratchet (6) and ratchet spring is arranged between one end of this axle (10) and its support (13), and the other end of tensioning shaft (10) is that regular polygon termination (8) is (such as square, the termination of regular hexagon nut structure), the aperture (9) that steel wire head is arranged to penetrate on the tensioning shaft (10), steady pin (19) is housed on the support (13), it is upper and an end is inserted in the aperture (9) of tensioning shaft (10) to be fixedly connected on steady pin (19) as steel wire (14) the pile warp steel wire guide wheel (5) of curtain rail and one end, and steel wire (14) rotates (clockwise rotating as shown in drawings) with tensioning shaft (10) and is tensioned. Install flap additional at described left and right base (1) (2), just make it become box body, favourable attractive in appearance. Described left and right base (1) (2) is relative concept, namely sees into and is left and right base (1) (2) in the face of accompanying drawing paper, and be that former left base becomes right base and former right base is left base and found out by paper.

Design principle of the present utility model and using method are, left and right base (1) (2) is installed in respectively window top arranged on left and right sides, put on stay cord (15), steel wire (14) is walked around steel wire guide wheel (5), and it is upper and the termination of the other end is inserted in tensioning shaft (10) that an end is fixedly connected on steady pin (19) Aperture (9) in, with the spanner termination (8) that turns clockwise, steel wire (14) be tensioned (referring to accompanying drawing) then. Because the effect of ratchet mechanism, the steel wire of tensioning (14) can not answered pine. Curtain is suspended on described steel wire (14) upper (single width curtain hang over arbitrarily on the side steel wire double width split curtain then be hung on the steel wire of both sides), and the same stay cord of curtain one side (15) is connected, then when the pulling stay cord, curtain is slided and the realization open and close at steel wire (14). Every side roller (3) of assembly pulley (3) (4) or (4) can be made up of one or two pulleys. The steel wire strainer of this device can be easily with the steel wire tensioning, in the time will changing clothes curtain, can unclamp ratchet (6) and loosens steel wire (14), and curtain is taken off.

As known from the above, the utility model is a kind of Curtain switch, and is simple in structure and cost is low, is easy to the tensioning steel-wire track and keeps curtain straight not sagging, and be easy to take off curtain, and performance is good, easy to use.

Embodiment: according to the Curtain switch of accompanying drawing and said structure, base (1) (2) size (long * wide) is respectively 80 * 55 millimeters, all adopts sheet metal to make; Steel wire (14) adopts 1.6 millimeters steel wires of φ, and assembly pulley (3) (4) respectively is two, and termination (8) are the regular hexagon nut structure, and left and right two bases (1) (2) are wide and decide apart from form.
