Hollow glass built-in shutter with shutter blind lifting balance function

Abstract

The invention provides a hollow glass built-in shutter with a shutter blind lifting balance function, and belongs to the technical field of sunshade hollow glass products. The hollow glass built-in shutter comprises a shutter body and an inner controller, wherein the shutter body is formed by connecting an upper transverse frame pipe, a lower transverse frame pipe, a left longitudinal frame pipe and a right longitudinal frame pipe through frame pipe end corner connecting pieces in an inserted and embedded mode, an upper transverse frame strip is inserted into the length direction of the side, facing downwards, of the upper transverse frame pipe in a matched mode, an upper transverse frame strip cavity is formed in the length direction of the upper transverse frame strip, a right longitudinal frame strip is formed on the left side of the right longitudinal frame pipe, and a right longitudinal frame strip cavity is formed in the height direction of the right longitudinal frame strip; and the inner controller is arranged in the right longitudinal frame strip cavity. The hollow glass built-in shutter is characterized by further comprising a shutter blind lifting balance mechanism, and the shutter blind lifting balance mechanism is fixed to the left side of the right longitudinal frame pipe at the position corresponding to the lower portion of the inner controller and is further connected with the inner controller. A balancing weight is not needed, the strict requirement for magnetic attraction force of the inner controller and an outer controller is reduced, a shutter blind can fully descend or be reliably kept at the expected position in the ascending state according to needs, and the requirement for shutters of different specifications and sizes can be conveniently avoided.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a hollow glass built-in blind with the function of lifting and balancing the blind. Background technique [0002] There are at least two structural forms of the aforementioned hollow glass built-in shutters, one is a double-glass single-cavity structure, and the other is a three-glass double-cavity structure. The former is set in the space between two inner glass and outer glass that are arranged facing each other Venetian blinds, the latter is to set the venetian blinds in the space between two inner glass facing each other and the middle glass. Examples of the former are examples of double-glass single-cavity structures such as CN2564720Y (hollow glass with built-in venetian blind), CN2767624Y (built-in louver in hollow glass), CN2767625Y (louver in hollow glass with improved structure), CN209067077U (unilaterally controlled double-layer hollo...

Problems solved by technology

However, when the counterweight (usually a lead weight with a relatively large specific gravity) is too heavy or too long, the venetian blind will "bounce" when it is close to fully unfolded, which will affect the fully unfolded effect of the venetian blind. In other words, there is an undesired space between the bottom bar of the lower part of the venetian blind and the lower horizontal frame tube of the form that is not covered by the venetian blind, which is extremely detrimental to protecting indoor privacy; on the contrary, in large-sized venetian blinds Under such circumstances, because the length of the counterweight is difficult to guarantee, the venetian blind will appear abnormally down when it is close to being fully retracted, which cannot meet the user's requirement for the venetian blind to stay at the desired position

If the width of the counterweight is increased, on the one hand, it is necessary to increase the width of the chute of the inner frame bar and increase the width of the inner controller at the same time, otherwise it will affect the inner manipulator and the counterweight follow the inner frame bar. The sliding effect of the chute, on the other hand, after increasing the width of the counterweight and the inner frame strip, the lighting area of ​​the hollow built-in blinds will be affected. Therefore, increasing the width of the counterweight to make up for the aforementioned unfavorable factors is often counterproductive ; If the thickness of the counterweight is increased, it is necessary to make adaptive changes to the size of the window and the inner frame, and to increase the width of the hollow cavity between the inner and outer glass accordingly, so that the entire hollow The pattern of built-in shutters has a fundamental impact and is therefore also not advisable

It can be seen from the above that although the setting of the counterweight has the advantages of labor-saving operation and can also play an auxiliary role in increasing the compensation for the lack of magnetic attraction force of the inner and outer manipulators, but the aforementioned two unfavorable factors are difficult to eliminate
