Single control double-layer hollow glass built-in shutter

Abstract

The invention discloses a single control double-layer hollow glass built-in shutter. The single control double-layer hollow glass built-in shutter comprises a rectangular window body, an inner frame and a tensioning mechanism, wherein the inner frame is arranged in the rectangular window body; a left frame cavity is formed in the left side of the inner frame; a right frame cavity is formed in theright side of the inner frame; an upper frame cavity is formed in the upper part of the inner frame; a space between the left side and the right side of the inner frame is a shutter cavity; a shuttersheet turning and shutter lifting control mechanism is arranged in the right frame cavity; a manual operation control mechanism is actuated with the shutter sheet turning and shutter lifting control mechanism in a manner of being separated from front glass; a shutter is arranged in the shutter cavity; a turning shaft driving mechanism is arranged between the right end of the upper frame cavity andthe upper part of the right frame cavity; the tensioning mechanism is fixed in the right frame cavity. The single control double-layer hollow glass built-in shutter has the characteristics that the shutter sheet turning and shutter lifting control mechanism comprises a turning shaft and a pulling rope winding device; the pulling rope winding device comprises first and second rotary shaft head supporting seats of a pulling rope winding roller, first and second rotary shaft heads of the pulling rope winding roller and the pulling rope winding roller. A shutter pulling rope is prevented from being damaged due to friction; the single control double-layer hollow glass built-in shutter has the advantages of good lifting stability, labor saving in operation and convenience in production and assembly.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a single-control double-layer hollow glass built-in shutter. Background technique [0002] The concept of single control mentioned above refers to the lifting or lowering of the venetian blinds and the flipping of the venetian blinds by a curtain flipping, venetian blind lifting control mechanism and a manual operation control mechanism, because the prior art requires Equipped with two independent control mechanisms for the lifting of the venetian blind and the flipping of the curtain, so the structure of the single control is relatively simple and can significantly reduce the cost of double-layer insulating glass built-in blinds. Also refer to paragraph 0004 of the description of the invention patent application publication number CN104747054A (double-glazed built-in blinds). [0003] The double-layer hollow glass built-in blinds mentioned abo...

Problems solved by technology

[0008] However, since all the above-mentioned patents, including CN105064896B, use the venetian blind lifting traction rope for lifting and lowering the venetian blind sheet on the traction pulley (for a typical example, please refer to the description of the invention patent authorization announcement number CN106467468B), Therefore, there are the following disadvantages: one, because the venetian blind lifting traction rope rubs against the traction pulley every time the venetian blind is raised and lowered, it is not enough to really and effectively protect the venetian blind lifting traction rope and traction pulley; There are many inflection points of the lifting traction rope, so the lifting stability is relatively poor and the operation is relatively laborious; third, due to the complex structure, it causes troublesome processing and assembly and is uneconomical
