Technical Field
The invention relates to a rolling curtain, in particular to a spring type curtain balancer and a rolling curtain without a pull rope.
Background
The general curtain can be structurally divided into a pull rope type curtain and a pull rope-free type curtain, wherein the pull rope type curtain mainly utilizes one pull rope to drive the curtain body to perform unfolding or folding actions, the pull rope-free type curtain utilizes hands to apply upward or downward force below the curtain body, and the pull rope type curtain is driven by a transmission mechanism to enable the curtain body to achieve the unfolding or folding effects. The existing curtain is mainly structurally characterized by comprising a scroll, curtain cloth and a reset spring, wherein the rolling force of the reset spring is equal to the weight of the curtain cloth, and therefore the curtain cloth can be moved upwards or downwards by applying upward or downward force under the curtain body by hands. In the production process, the elastic force of the reset spring is required to be continuously selected and adjusted to match with the curtain cloth with different lengths, thicknesses and materials, when the elastic force of the reset spring is smaller, the curtain cloth automatically moves downwards, and when the elastic force of the reset spring is larger, the curtain cloth automatically moves upwards, so that hovering at any position cannot be realized. And the machining precision of each spare and accessory part is required to be high, otherwise, when the transmission force of each spare and accessory part changes after long-term use, the problems are caused. In summary, the existing pull-rope-free curtain has large production and processing difficulty and high cost, and cannot be popularized on a large scale.

The utility model provides a no-pull rope rolling type curtain, includes the curtain mount pad, sets up the curtain pivot on the mount pad, sets up reset spring in the curtain pivot, winds at the epaxial curtain of curtain, be connected with spring type curtain balancer in the curtain pivot, spring type curtain balancer includes the installation cover of being connected with the curtain pivot, sets up friction shaft and the cover establish at epaxial spiral torsion spring of friction in the installation cover, friction shaft and mount pad fixed connection, the both ends of spiral torsion spring outwards stretch out respectively and form the driving lever, the inner wall of installation cover is equipped with inwards bellied dog, the dog is located between the driving lever at spiral torsion spring both ends.
In the invention, a movable gap exists between the stop block and the deflector rods at two ends.
In the invention, the contact surface of the spiral torsion spring and the friction shaft is an antifriction surface.
In the invention, the bottom of the curtain cloth is connected with a hanging piece.
The beneficial effects of the invention are as follows: when the curtain rotating shaft rotates to drive the curtain to move up and down, relative motion exists between the friction shaft and the spiral torsion spring and friction force is generated, for example, the reset elastic force of the reset spring is X, the weight of the curtain and the weight of the hanging piece are Y, and the maximum static friction force between the friction shaft and the spiral torsion spring is F.
