Bead-chain driven double-glazed built-in shutters

Abstract

The invention discloses a bead chain driving type double-layer hollow glass built-in louver and belongs to the technical field of sunshade hollow glass products. The louver comprises a window body, a curtain piece turning mechanism, a venetian blind, an inner control mechanism, an outer control mechanism and a venetian blind lifting traction rope. The window body comprises an upper window body transverse tube, a lower window body transverse tube, a left window body longitudinal tube, a right window body longitudinal tube, inner glass and outer glass. The louver is characterized in that the inner control mechanism comprises a box body, a box cover, a synchronous belt pulley, a synchronous belt and a lifting traction rope driving wheel. The outer control mechanism comprises a protective cover, a friction plate, a bead chain wheel shaft, a bead chain wheel shaft hub, a bead chain and a bead chain wheel shaft base. The protective cover forms a protective cover cavity. The friction plate is arranged in the protective cover cavity. The bead chain wheel shaft hub is supported by a shaft hub cavity. The bead chain wheel shaft is arranged in the middle of the bead chain wheel shaft hub. One end of the bead chain is arranged on the bead chain wheel shaft hub in a sleeving mode. The other end of the bead chain forms a suspending end. The bead chain wheel shaft base is matched with the protective cover. One end of the venetian blind lifting traction rope is in driving connection with a lifting traction rope driving wheel. Manufacturing cost is reduced; labor is saved during operation; service life is long, and the using effect is good; resource-saving economy is reflected.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, in particular to a bead chain driven double-layer hollow glass built-in shutter. Background technique [0002] The double-layer hollow glass built-in blinds mentioned above refer to the construction of a venetian blind that can be raised and lowered as needed in two pieces of glass (inner glass and outer glass) that are arranged in a face-to-face state and that seal the surrounding edges. A window belonging to the category of sunshade hollow glass products. This kind of window has the following self-evident advantages: good heat insulation, so as to reflect the energy saving of the building; excellent sound insulation, so as to avoid the disturbance of external noise; Expected bright effect; through the adjustment of the deflection angle of the venetian blinds, the required indoor lighting requirements can be obtained, privacy can be protected, and the venetian blinds can ...

AI Technical Summary

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: First, due to the fact that each group of magnets that are usually equipped on the blinds lifting controller and the traction inner slider The quantity is at least three or more, and the magnet is a strong magnet, and because the price of this magnet is very expensive, the blinds are not economical and cheap; second, because the volume of the blind lift controller is limited, it is not conducive to operation. Thirdly, because a group of magnets are embedded in the outer slider housing of the venetian blind lifting controller made of plastic and the inner slider embedded in the traction inner slider In the block shell, because the magnet and the shell are made of different materials, the thermal expansion and contraction coefficients are different and the difference is large, and because the plastic is naturally aged and even deformed over time, after a certain period of use, the shell The ability to control the magnet is gradually weakened, and even the phenomenon of magnet dislocation and falling off occurs, which affects the mutual magnetic attraction effect between the blind lifting controller and the traction inner slider; fourth, because the magnet is a rare earth permanent magnet, and rare earth is a precious strategic resources, so there is a problem of large resource consumption
