Single-side dual-control hollow glass built-in louver with labor-saving operation

Abstract

The invention provides a single-side dual-control hollow glass built-in louver with labor-saving operation, and belongs to the technical field of shading hollow glass products. The single-side dual-control hollow glass built-in louver with labor-saving operation comprises a window body, inner glass, outer glass, a curtain piece turnover transition mechanism, a venetian blind, a drive controller for driving the venetian blind to rise and fall and curtain pieces to turn over, a curtain piece turnover traction rope, a venetian blind lifting traction rope, a corner base and a turnover shaft. The drive controller comprises a curtain piece turnover inner control mechanism, a curtain piece turnover outer control mechanism, a venetian blind lifting inner control mechanism and a venetian blind lifting outer control mechanism. The single-side dual-control hollow glass built-in louver with labor-saving operation is characterized in that the drive controller further comprises a balance weight anda traction rope connecting base, the balance weight is connected to the lower portion of the venetian blind lifting inner control mechanism, the traction rope connecting base is fixed to the window body, the upper portion of the traction rope connecting base is further sleeved with the middle of the curtain piece turnover traction rope, and one end of the venetian blind lifting traction rope is fixed to the lower portion of the traction rope connecting base. The interference influence on opening of adjacent windows is avoided; the shielding effect is good, and the privacy and the safety are guaranteed; dies are saved, and the assembly efficiency is improved; the structure is compact; labor is saved in operation.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a single-side double-control hollow glass built-in blind with labor-saving operation. Background technique [0002] The hollow glass built-in shutters mentioned above refer to the two pieces of glass (inner glass and outer glass, also called front glass and rear glass) that are arranged in a face-to-face state and seal the surrounding edges. The window that belongs to the category of sunshade hollow glass products is composed of lifting venetian blinds. This kind of window has the following advantages self-evidently: good heat insulation to reflect the energy saving of the building; excellent sound insulation to avoid the noise of the outside world. Intrusion; anti-condensation and frost to ensure sufficient indoor light and reflect the desired bright effect; through the adjustment of the deflection angle of the blinds, in order to obtain the re...

Problems solved by technology

[0007] However, the above-mentioned CN105041169B still has the following disadvantages: First, due to the transition sliding mechanism (equivalent to the internal control mechanism for curtain flipping) that is located between the inner glass and the middle glass in the inner hollow cavity and is used to turn the curtain The internal lifting and sliding mechanism (equivalent to the internal control mechanism for the venetian blind lifting) is connected to each other, so when the manual operation control mechanism (equivalent to the external control mechanism) drives the transitional sliding mechanism to turn the curtains over, the transitional sliding mechanism It needs to move up or down, only this can drive the curtain flipping rope and the angle required for the curtain flipping to be driven by the curtain flipping rope, so when the transition sliding mechanism moves up or down, the inner lifting sliding mechanism connected with its lower part There will also be a step-by-step upward or downward displacement, especially when the lower part of the venetian blind will rise when it is displaced upwards, the abnormal opening space will be generated, which will affect the indoor shielding effect, because it is easy to observe from the above-mentioned abnormal opening space outdoors In the room, it is not conducive to privacy and security protection; secondly, through reading the full text of the specification of CN105041169B, it can be known that due to the inner frame bars and outer frame tubes (i.e. "frame tubes" of the structural system of the window, the same below). ) is an independent structure that forms a split type with each other, that is, the two are first manufactured with their own independent parts, and then organically combined during assembly, which not only leads to a large amount of mold investment, but also causes assembly troubles, which affects assembly efficiency; Three, because the curtain flipping rope redirecting parts for flipping the blinds and the venetian blind lifting traction redirecting parts for raising and lowering the venetian blinds are not in the same The carrier forms a reasonable assembly relationship like a corner seat, thus causing the part to lose simplicity and significantly increase the volume; The sliding rollers and the rollers of the manual operation sliding seat of the manual operation control mechanism all use traditional plastic rollers, so the friction between these rollers and the glass is large, making the operation laborious; The operation of raising (that is, opening the venetian blind) is often laborious, and the venetian blind in the open state will also appear to slide down abnormally, because it is difficult to ensure that the venetian blind is stopped only by the magnets that are magnetically attracted to each other across the glass , unless the number of magnets is increased or the volume of the magnet is increased, but it will increase the cost
