Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings:
Fig. 1 is the top view of complete curtain dragging device；
Fig. 2 is the top view for removing the curtain dragging device after cord and draw bar；
Fig. 3 is the schematic diagram of draw bar cross section；
Fig. 4 is the enlarged drawing of connector position.
Specific embodiment
Referring to figs. 1 to Fig. 4, the present invention is a kind of curtain dragging device.Including curtain body, curtain body include shell,
Shaft and cord 1 in shell, cord 1 is in shaft.
This programme proposes to improve for the cord 1 of abnormity, and the front end of special-shaped cord 1 is narrower than the maximum width of cord 1, curtain
The left and right edges of cloth 1 are bevel edge.Bevel edge is that the cord 1 of straight line has these moulding of isosceles trapezoid, right-angled trapezium, triangle；Bevel edge
There is this moulding of ellipse for the cord 1 of camber line.These abnormity cords 1 storage when and traditional rectangular cord storage mode
Equally, in shaft.
Curtain dragging device further includes the guide rail 2 positioned at the draw bar 4 of 1 front end of cord and positioned at 1 left and right sides of cord, from
It is seen perpendicular to the direction of 1 place plane of cord, cord 1 is trapped among centre by two guide rails 2, draw bar 4 and shell, and draw bar 4 presss from both sides
The front end of cord 1 is held, two guide rails 2 are parallel with the left and right edges of cord 1.Parallel pin described here to bevel edge be straight line and
Speech, since guide rail 2 is usually straight line moulding, if bevel edge is camber line, then the less parallel as far as possible of guide rail 2 also may be used close to bevel edge.
The longitudinally projecting length of cord 1 is substantially equal to the length of guide rail 2 in a longitudinal direction.
Curtain dragging device further includes two connectors 3 for being arranged in 4 left and right ends of draw bar, and the connector 3 includes
The slide 31 and long guide rod 33 to interconnect, the slide 31 are slidably connected with guide rail 2, the long guide rod 33 and traction
Bar 4 is slidably connected, and the glide direction of long guide rod 33 and the length extending direction of draw bar 4 are parallel.When connector 3 moves forwards, backwards
When, guide rod 33 long first drives draw bar 4 to be moved forward and backward, and since long guide rod 33 and 31 relative position of slide are constant, then embodies
The depth for being inserted into draw bar 4 for long guide rod 33 changes, but final effect is that long guide rod 33 still can be supported steadily and be led
Draw bar 4, no matter draw bar 4 can keep stable in any position, avoids shaking, i.e. the process that the cord 1 of abnormity is pullled
In the state that is always maintained at stable state, needless to say is fully deployed or packs up.The curtain dragging device is ingenious in design, and transmission is steady
It is fixed, compensate for blank in the market.
In other embodiments, the surface setting groove of draw bar 4 is for storing long guide rod 33, at the same time, draw bar 4
Surface also can be set groove clamping cord 1.Preferably, the draw bar 4 is profile, portable construction and intensity is enough,
The inside of the outer profile approximate ellipsoidal of the draw bar 4, the draw bar 4 has containing cavities 41 and holding chamber 42, containing cavities
41 are located at front side, and holding chamber 42 is located at rear side.The long guide rod 33 is inserted into containing cavities 41 and slides in containing cavities 41, the folder
Chamber 42 is held to be fixedly connected with the front end of cord 1.By taking Fig. 3 as an example, the section in Fig. 3, which is stretched, can obtain draw bar 4.
In other embodiments, long guide rod 33 is cylindrical structure, and correspondingly containing cavities 41 are circular hole.In order to allow long guide rod 33
Sliding between draw bar 4 is more smooth, preferably, the long guide rod 33 is equipped with several idler wheels, idler wheel and containing cavities 41
Inner wall contact.The cross section of the containing cavities 41 is closed rectangle；The cross section of the holding chamber 42 is U-shaped, the folder
It holds and is equipped with the multipair protrusion mutually drawn close in chamber 42, cord 1, which is inserted into, to be completed to fix between adjacent two protrusion.It can see in Fig. 3
There are three pairs of protrusions, two pairs of protrusions in outside, innermost protrusion is in U-shape.
In other embodiments, the surface of long guide rod 33 is arranged in idler wheel.Preferably, the centre of long guide rod 33 is with more
At least one idler wheel is arranged in each slotted hole in a slotted hole being spaced apart from each other, and slotted hole suitably protects idler wheel, the portion of idler wheel
Divide the surface of the prominent long guide rod 33 in edge.On the basis of the orientation in Fig. 3, part or all of idler wheel can be upper with containing cavities 41
Lower inner wall contact, part or all of idler wheel can also be contacted with the left and right inner wall of containing cavities 41.
In other embodiments, slide 31 and long guide rod 33 are directly hinged.In order to make long guide rod 33 opposite with slide 31
Position can be arranged for greater flexibility, for example draw bar 4 is facilitated to be bonded shell, the position conflict etc. between component be reduced, as excellent
Choosing, the connector 3 further include connecting rod 32, and the head and the tail both ends of connecting rod 32 are hinged with slide 31 and long guide rod 33 respectively, the company
Bar 32 is L shape, and one end of connecting rod 32 is parallel with the glide direction of slide 31, the sliding side of the other end of connecting rod 32 and long guide rod 33
To parallel.
Guide rail structure belongs to the prior art, and how general description guide rail 2 works here.The guide rail 2 include gear set and
The conveyer belt being wrapped on gear set, conveyer belt are divided into upper layer and lower layer, slide 31 and conveyer belt wherein one layer be fixedly connected, when
The mobile length direction to follower link 3 along guide rail 2 of conveyer belt moves when external force drive gear set rotates.With technology
Development, also has a small amount of curved guide rail 2, in this case, guide rail 2 can be preferably bonded 1 edge of cord at present.Obviously
The curtain dragging device on ground, this programme is still applicable in, and long guide rod 33 still can drive 4 forward-reverse of draw bar, while keep taking out
Slotting state.
In assembly, the shell and two guide rails 2 are fixed on the rack entire traction device, are additionally provided in the rack
Motor, motor drive the gear set in two guide rails 2 by transmission mechanism.Not only curtain dragging device, this programme also mention
A kind of practicable blind system is supplied.
Certainly, the design creation is not limited to above embodiment, and the combination of the various embodiments described above different characteristic can also
To reach good effect.Those skilled in the art can also make equivalent change on the premise of without prejudice to spirit of the invention
Shape or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
