Non-magnet driven double-glazed built-in shutters

Abstract

The invention discloses a non-magnetic driven type blind window with internally-installed double-layer hollow glass, and belongs to the technical field of sunshade hollow glass products. The non-magnetic driven type blind window with the internally-installed double-layer hollow glass comprises a window body which comprises inner glass and outer glass, a blind sheet turning mechanism, a venetian blind, an internal manipulation mechanism, an external manipulation mechanism and a venetian blind lifting pulling rope. The non-magnetic driven type blind window with the internally-installed double-layer hollow glass is characterized in that the internal manipulation mechanism comprises a case body, a case cover, a synchronous pulley, a synchronous belt and a lifting pulling rope driving wheel, the case body is arranged in a hollow cavity and fixed with the window body, the synchronous pulley is located above the case body cavity, one end of a synchronous pulley shaft is supported on the case cover, and the other end of the synchronous pulley shaft is supported on the cavity bottom wall of the case body cavity; one end of the synchronous belt is arranged on the blind sheet turning mechanism in a sleeving mode, and the other end of the synchronous belt is arranged on the synchronous pulley in a sleeving mode; the lifting pulling rope driving wheel is arranged in the case body cavity of the case body and located on the lower portion of the case body cavity; the external manipulation mechanism comprises a shield, a friction disc, a bead chain wheel shaft, a bead chain wheel hub, a bead chain and a bead chain wheel shaft seat; one end of the lifting pulling rope of the venetian blind is connected with the lifting pulling rope driving wheel. Therefore, resources are saved, the cost is reduced, and the labor is saved in operation.

Description

Technical field [0001] The invention belongs to the technical field of sun-shading hollow glass products, and specifically relates to a non-magnet-driven double-layer hollow glass built-in shutter. Background technique [0002] The above-mentioned double-layer hollow glass built-in louver refers to the two pieces of glass (inner glass and outer glass) that are arranged in a state of facing each other and are closed around the edges of the glass (inner glass and outer glass). A window belonging to the category of sun-shading hollow glass products. This kind of window has the following advantages, which are self-evident: good heat insulation, which reflects the energy saving of the building; excellent sound insulation, which prevents external noise and noise; prevents condensation and frost, which ensures sufficient indoor light and reflects The desired bright effect; by adjusting the deflection angle of the blinds of the venetian blinds, it can achieve the required indoor lightin...

Problems solved by technology

Although the double-layer hollow glass built-in blinds of this structural system can meet the actual use requirements, there are the following shortcomings: one, because the number of each group of magnets that are usually equipped with the outer operating mechanism and the inner operating mechanism is at least More than three, and the magnet is a strong magnetic magnet, and because the price of this magnet is very expensive, thereby causing the double-layer hollow glass built-in blinds to lose the economy and cheapness; It is beneficial to grip and pinch during operation, especially for the elderly to cause certain operational confusion; thirdly, because a group of magnets are respectively embedded in the inner control mechanism and the outer control mechanism in the plastic shell, and because the magnet and the shell The body is made of dissimilar materials, and the thermal expansion and contraction coefficients are different and greatly different. Also, due to the natural aging and deformation of the plastic over time, after a certain period of use, the shell's ability to control the magnet gradually weakens, and even appears The phenomenon of magnet dislocation and falling off affects the mutual magnetic attraction effect of the inner and outer control mechanisms; Fourth, because the magnet is a rare earth permanent magnet doped with rare earth elements, and rare earths are valuable strategic resources, there is a problem of large resource consumption. question

[0006] If the magnets are discarded for the inner control mechanism and the outer control mechanism, the above-mentioned technical problems can basically be remedied, but in the Chinese and foreign patents and non-patent documents disclosed so far, there is no such thing as a non-magnet-driven double-layer hollow glass built-in shutter. technical inspiration
