Abstract

The utility model relates to a device for opening and closing curtains, which lifts hangings of hanging curtains vertically by hand. The utility model is mainly composed of a hanging curtain machine frame (4), a rolling wheel (2), a rocker (5), a ratchet mechanism (6), a cam (8), and a tension spring (7). The utility model has the advantages of simple structure, convenient installation, and easy manufacture. The utility model can stay the hangings of the hanging curtains at any position, can be lifted stably, and can be dropped down flat.

Description

Vertical-lifting curtain pulling device

The utility model relates to a kind of curtain device that draws of made cord vertical lift manually.

That generally uses at present draws the curtain device type many, but with elevator and stay cord is that headstock gear is in the majority, particularly allow the curtain device that draws of curtain vertical lift, existing problems mainly are arbitrarily to rest on curtain on the optional position, and the cord that rises generally is to adopt the rolling ring formula to rise, often cause the off-centre of roller shutter in uphill process, the door curtain made of cloth is stuck and can not rises to the top fully.

It is a kind of simple in structure that the purpose of this utility model is to provide, and easy to use and existingly draws curtain device diverse, utilizes and manually can make curtain vertical lift, and the device that can stop in any position.

The utility model is to finish as follows, this device is mainly by curtain machine frame, roller, rocking bar, ratchet mechanism, cam spring is formed, roller is separately fixed on the frame, on rightmost roller, rocking bar is housed, the rocking arm of rocking bar and the hinge joint of ratchet mechanism front end, the rear end of ratchet mechanism is positioned on the frame, the garden cambered surface that is positioned at the frame overhead cam is squeezed in the groove of roller, also has a tension spring on the cam.

The utility model is simple in structure, production cost is low, use, easy for installation, adopts this device to make to draw cord to stop on the optional position when rising or descend, and steady when rising, and descending, it is straight well-pressed to launch.

Further specify in conjunction with the accompanying drawings, Fig. 1 is that vertical lift draws the curtain device plane.

With reference to Fig. 1 explanation, be separately installed with roller (2) on the utility model curtain frame (4), go up to twine stay cord (3) at wheel (2)) rocking bar (5) and ratchet mechanism (6) hinge joint be housed on right-hand member roller (2), be squeezed on the cam (8) in roller (2) groove and adorn an extension spring (7), cam (8) is that will to clamp ratchet mechanism (6) around the stay cord (3) on the roller (2) by the pulling force of extension spring (7) be promptly to be extended by an action, square contracts, stay cord whenever spurs a just once action of conversion of ratchet mechanism left, slack rope when it extends, shorten tight rope, pulling cord (3) left, rocking bar (5) is to anticlockwise, depress the pin (9) on the cam (8), cam (8) is rotated down, ratchet (6) elongation simultaneously, this moment, rope was a relaxation state, curtain leans on from vertical drop, when spurring rope (3) again, ratchet (6) shortens, spring (7) then upwards spurs cam (8) stay cord (3) is compressed, and cord stops to fall, in this state, vertical pulling stay cord (3) cord rises, and can rest on the optional position.

Cord can be fixed on the frame (2) with clip, middle is the aperture of 100mm according to rope apart from beating four fundamental rules (or more) spacing, the below of cord penetrates channel bar (1), four stay cords (3) penetrate aperture respectively, and it is fixing with cross bar (1), like this from right-hand member with pulling moving stay cord, then cord can be mentioned, cord is folded on the cross bar (1) uniformly.Roller (2) on the frame (4) can be according to the size quantification and the distance of cord, rocking bar (5) and ratchet mechanism (6) but can be made into metalwork or plastics all the garden cambered surface of cam (8) be to make the file face specially, purpose is to strengthen friction.

Claims (2)

1, a kind of vertical lift draws curtain device, form by curtain frame (4), roller (2), rocking bar (5), ratchet mechanism (6) cam (8), extension spring (7), it is characterized in that, rocking bar (5) upper end connects with right-hand member roller (2), is positioned at ratchet mechanism lower end and rocking bar (5) hinge joint on the frame (4).The garden cambered surface that is positioned at the cam (8) on the curtain frame (4) is squeezed in the groove of roller (2).

2, vertical lift according to claim 1 draws curtain device, it is characterized in that a pin (9) and extension spring (7) are housed on the cam (8), and its garden cambered surface is the file face.
