Description
Technical field
Present invention relates particularly to a kind of venetian blinds.
Background technology
Venetian blind is for covering the opening of window and door, to obstruct light and to keep privacy.With national economy
Development, requirement of the people to quality of the life improve day by day, and window decorations product also rapidly grows up, and blinds is as a kind of page turning tune
The feature-rich product of light, application demand are more and more.
Traditional venetian blind includes head track, blind, underbeam, the driver risen or fallen for adjusting blind
Structure, the adjustment mechanism that angle is opened and closed for adjusting blade, transmission mechanism includes drive rod and winder.Existing venetian blind
Head track in be provided with clutch so that blind can realize semi-automatic decline function, all be the weight by blind itself
Amount moves down, and when blind weight kicks the beam, is stopped when blind can be made to drop to half, then obtains and passes through drawstring by hundred
Leaf curtain drops to bottommost, has influenced the use of user and the time cost of loss in this way；When blind is overweight, hold
It easily leads to blind rapid decrease and makes head track by larger pulling force, length can make Top Tank insecure long afterwards, be easy to cause
Security risk.
Invention content
Based on the above issues, present invention aims at providing, one kind is simple in structure, service life is long and can prevent blinds
The venetian blind for falling on half under curtain and stopping.
In view of the above problems, providing following technical solution：A kind of venetian blind, including drawstring, head track, transmission mechanism,
Head and blind processed, the transmission mechanism include drive rod and the winder and clutch that are set on drive rod, described
It is equipped with driving-aid mechanism in head track, the driving-aid mechanism includes box body, gear set, head cover and the wind spring being located in box body, described
It is equipped with the first fixed column and the second fixed column in box body, first fixed column box body opposite with the second fixed column is rotatable, institute
The one ends wound of wind spring is stated in the first fixed column, other end end is fixed in the second fixed column, is equipped at the top of the box body
Groove, the gear set include being located at the first gear in groove and being fixed in the second fixed column and being located at slot opening
With the second gear of first gear cooperation, the second gear is equipped with the first axle sleeve, opposite with the first axle sleeve on the groove
Position at be equipped with the second axle sleeve, first axle sleeve and the second axle sleeve are set on drive rod, are arranged on the drive rod
Damper.
In above structure, by the cooperation of drawstring and clutch, blind is enabled to rely on the weight of venetian blind underbeam
Power declines automatically.The rotating speed that drive rod can be slowed down by damper, to prevent blind to decline pressure that is too fast and generating
Power leads to that blind falls off from head track or head track falls off from wall.The one ends wound of wind spring is in the first fixed column, the other end
End, which is fixed in the second fixed column, enables to one end of wind spring to generate pretightning force, when blind declines, drive rod rotation,
Second fixed column is rotated by the pretightning force of wind spring, and to drive first gear to rotate, first gear drives second gear
Rotation, second gear help drive rod to rotate, stop when preventing blind from dropping to half by the first axle sleeve.Second axle sleeve energy
It is enough that drive rod is limited so that drive rod is connect more stable with driving-aid mechanism.When blind rises, drive rod rotation,
Second gear drives first gear rotation, so that the second fixed column discharges wind spring, wind spring is rewound to the first fixed column
On.
The present invention is further arranged to, and the damper uses unidirectional hydraulic damper.
Using the above structure, muting function is good when blind declines, and enables to blind only when declining, damping
Device can just act.
The present invention is further arranged to, and the winder is at least provided with two groups, and opposite blind center line symmetrical setting
In head track.
Using the above structure, the stability that blind rises or falls can be increased.
The present invention is further arranged to, and the head cover is located on groove and is fastened by screw with it.
Using the above structure, it can prevent dust from entering in groove and influencing gear set rotation.It is arranged to removably tie
Structure being capable of easy to repair and cleaning.
Beneficial effects of the present invention：Compared to existing venetian blind, the configuration of the present invention is simple, stability are high, can save
The time service life of user is long and can prevent from falling on half under blind and stopping.It can slow down driving by damper
The rotating speed of bar leads to that blind falls off from head track or head track is from wall to prevent blind to decline pressure that is too fast and generating
On fall off, increase the present invention safety.

Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
A kind of venetian blind as shown in Figure 1 to Figure 3, including drawstring 1, head track 2, transmission mechanism 5, head processed 3 and blinds
Curtain 4, the transmission mechanism 5 include drive rod 51 and the winder 52 being set on drive rod 51 and clutch 53, the top

Device 9.
In above structure, by the cooperation of drawstring 1 and clutch 53, blind 4 is enabled to rely on venetian blind underbeam
Gravity decline automatically.The rotating speed that drive rod 51 can be slowed down by damper 9, to prevent blind 4 decline it is too fast and
The pressure of generation leads to that blind 4 falls off from head track 2 or head track 2 falls off from wall.The one ends wound of wind spring 64 is solid first
On fixed column 611, other end end, which is fixed in the second fixed column 612, enables to one end of wind spring 64 to generate pretightning force, when hundred
When leaf curtain 4 declines, drive rod 51 rotates, and the second fixed column 612 is rotated by the pretightning force of wind spring 64, to driving first
Gear 621 rotates, and first gear 621 drives second gear 622 to rotate, and second gear 622 helps drive rod by the first axle sleeve 7
51 rotations, stop when preventing blind 4 from dropping to half.Second axle sleeve 8 can limit drive rod 51 so that drive rod
51 connect with driving-aid mechanism 6 it is more stable.When blind 4 rises, drive rod 51 rotates, and second gear 622 drives first gear
621 rotations, so that the second fixed column 612 discharges wind spring 64, wind spring 64 is rewound to the first fixed column 611.
In the present embodiment, the damper 9 is using unidirectional hydraulic damper 9.Muting function is good when blind 4 declines, and
Enable to blind 4 only when declining, damper 9 can just act.
In the present embodiment, the winder 52 is at least provided with two groups, and opposite 4 center line symmetrical setting of blind is in head track
In 2.The stability that blind 4 rises or falls can be increased.
