Description
Technical field
The present invention relates to a kind of window treatment, specifically relates to a kind of spring curtain balancer and its without drawstring window treatment.
Background technology
In general curtain can divide into dragline type and non-dragline type in structure, wherein, dragline type curtain mainly utilizes
The action that one drawstring is deployed or folded to drive curtain to carry out, Non-pull-cord type curtain are then to utilize hand under curtain
Side bestows the strength faced upward or downward, and the drive again with unification transmission mechanism, allows curtain to be equally reached expansion or receive
The effect of conjunction.Existing no drawstring window curtain primary structure is as follows, including spool, cord, back-moving spring, wherein back-moving spring
Winding dynamics be equal to cord weight, can thus bestow the strength faced upward or downward below curtain by hand makes curtain
Cloth is moved up or moved down.In process of production, it is necessary to constantly apolegamy and adjustment back-moving spring elastic force come coordinate different length,
Length, thickness, the cord of material, when the elastic force of back-moving spring is smaller, cord moves down automatically, when the elastic force of back-moving spring is larger
When, cord moves up automatically, can not accomplish that optional position is hovered.And it is required that the machining accuracy of each spare and accessory parts is high, otherwise work as length
After long use, when the driving force of each spare and accessory parts changes, above mentioned problem is also resulted in.In summary, it is current without drawing
Rope type curtain production and processing difficulty is big, and cost is high, can not accomplish to popularize on a large scale.
The content of the invention
A kind of spring curtain balancer rational in infrastructure, difficulty of processing is small provided by the present invention and its without drawstring rolling
Curtain.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of spring curtain balancer, including the installation set that can be connected with curtain rotating shaft, the friction mandrel that is arranged in installation set
And the helical torsional spring on friction mandrel is set in, the both ends difference of the helical torsional spring is protruding and formation is dialled
Bar, the inwall of the installation set are provided with inwardly protruded block, and the block is located between the driving lever at helical torsional spring both ends.
In the present invention, free gap be present between the block and the driving lever at both ends.
In the present invention, the contact surface of the helical torsional spring and friction mandrel is rub resistance surface.
It is a kind of without drawstring window treatment, including curtain mounting seat, be arranged in mounting seat curtain rotating shaft, be arranged on curtain
Back-moving spring in rotating shaft, the cord in curtain rotating shaft, spring curtain balancer is connected with the curtain rotating shaft,
The spring curtain balancer is including the installation set being connected with curtain rotating shaft, the friction mandrel being arranged in installation set and is arranged
Helical torsional spring on friction mandrel, the friction mandrel are fixedly connected with mounting seat, the both ends point of the helical torsional spring
Not protruding and form driving lever, the inwall of the installation set is provided with inwardly protruded block, and the block is located at screw twisted
Between the driving lever of both ends of the spring.
In the present invention, free gap be present between the block and the driving lever at both ends.
In the present invention, the contact surface of the helical torsional spring and friction mandrel is rub resistance surface.
In the present invention, the cord bottom is connected with suspension member.
The beneficial effects of the invention are as follows：When curtain rotating shaft, which rotates, drives cord to move up and down, friction mandrel and screw twisted
Relative motion between spring be present and produce frictional force, for example, back-moving spring reseting elasticity be X, cord and suspension member weight
For Y, the maximum static friction force between friction mandrel and helical torsional spring is F, then when cord needs to reach optional position hovering
When, Y-F≤X≤Y+F ,-F≤X-Y≤F, therefore in process of production, during the elastic force of adjustment spring, only regulation arrive with cord with
And the weight difference of suspension member is in the range of maximum static friction force, without as traditional rolling screen without pull rope, it is necessary to strictly control
The elastic force of spring processed and cord and the weight difference of suspension member, reduce the production and processing difficulty of non-dragline type roller shutter, are easy to advise greatly
Mould is promoted.
