In the present invention, described rolling rope, damper and spring gear constitute the apparatus for controlling of lifting of this device, this apparatus for controlling of lifting is simple to operation, only need to be pulled by cover from sun with hand to allow it rest on optional position, and the described rolling rope that operates steadily is arranged at guide rail and solar protection devices body interior.
Further, first, second damper described comprises three beaming rollers respectively, and described beaming roller cross section becomes " isosceles triangle " arrangement, be arranged at top, lower-left, bottom right beaming roller be respectively first, second and third beaming roller, each beaming roller axial plane fits tightly.
Further, described rolling rope passed by described rope closing gear be wound in described damper again roll shaft on, described rolling rope after being first wound in described first beaming roller again through the contact surface second, third beaming roller described.
Further, described first beaming roller roll surface 1 ~ 3 week walked around by described rolling rope.
When pulling cover from sun, described rolling rope band moves described first beaming roller and rotates, described first beaming roller drives second, third beaming roller described to rotate to equidirectional, and due to second, third beaming roller roll surface described also close contact, it has the frictional force of both obstructions rotating in same direction mutually, therefore can produce resistance during the retractable action for described rolling rope of three beaming rollers, make cover from sun can rest on optional position after external force is removed.
Further, described upper/lower guide two ends are provided with guiding rail cover, and guiding rail cover is provided with cord hole.
Further, described upper/lower guide is provided with hand handle, makes the control of solar protection devices more convenient.
Implement the present invention, there is following beneficial effect:
Adopt the solar protection devices of spring gear box structure of the present invention, can realize any rolling and the expansion that control cover from sun without stay cord, avoid the stay cord being exposed to outside to twine the potential safety hazard of wound, it is simple to operation, only need to be pulled by cover from sun with hand to allow it rest on optional position, operates steadily.This invention overall appearance, easy to operate and applicability is strong.
