Description

Rotary magnetic transmission built-in sunshade hollow glass

Technical Field

The utility model relates to built-in sunshade hollow glass, in particular to rotary magnetic transmission built-in sunshade hollow glass.

Background

The existing built-in sunshade hollow glass generally comprises at least one hollow glass inner cavity, a frame and a built-in sunshade system such as a blind or a roller shutter, and the difference between various products mainly lies in an operation or transmission system. In the early single-handle or double-handle sliding magnetic transmission product, because the handle and the transmission mechanism are positioned in the frames on the left side and the right side, the frames on the two sides are wider, and the light transmission and lighting surfaces of the glass are reduced; in recent years, the electric operating products which are gradually accepted by the market still have the defect that the electric motor cannot be replaced or repaired because the electric motor is sealed and arranged in the upper frame.

The applicant has succeeded in recent years, and the patented technology of the hollow glass with built-in sunshade by the rotary magnetic transmission overcomes the defects of the former two, but the hollow glass is influenced by moment generated by the self weight of a sunshade object such as a louver and other factors, so that the louver can generate misoperation and generate certain lifting or deflection when the hollow glass is not operated by a person, and the sunshade effect is influenced. In particular, in some special application places, such as museum exhibits, exhibition halls or libraries, special personnel are required to be limited to take charge of the adjustment of the blinds and other sunshades, and other people are not allowed to adjust the sunshades at will.

Meanwhile, the magnetic transmission manual manipulator for the existing hollow glass has the disadvantages of complex structure, more parts, complex assembly process, time and labor waste and higher manufacturing cost.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rotary magnetic transmission built-in sunshade hollow glass, which can lock a rotating shaft of a shutter and other sunshades when needed, limit the rotation of the rotating shaft, keep the shutter at a specific lifting height and a specific deflection angle, and avoid deflection and misoperation; the utility model further provides a magnetic transmission manual manipulator which is simple in structure, few in parts, convenient to assemble and low in manufacturing cost and is used for the rotary magnetic transmission built-in sunshade hollow glass.

The magnetic control slide block and the stop element of the magnetic control stop device work in a matching way to limit or open the rotation of the rotating shaft. When an external magnetic transmission manipulator or other external magnetic elements are used for driving the magnetic control slider to be connected with the stopping element, the magnetic control slider is matched with the stopping element to limit the rotation of the driven magnetic transmission piece or the rotating shaft of the rope winder and lock the driven magnetic transmission piece or the rotating shaft, so that the sun shades such as shutters and the like are kept at a specific lifting height and a specific deflection angle; when the magnetic control slider is separated from the stop element, the limitation is removed, and the height and the deflection angle of the sun-shading objects such as the louver are restored to be adjustable. Namely, the utility model controls whether the rotating shaft is adjustable or not by the clutch of the magnetic control stop device, and finally realizes the control of the sun-shading objects such as the louver.
