Inward suction prevented single control hollow glass embedded shutter

Abstract

Disclosed is an inward suction prevented single control hollow glass embedded shutter. The inward suction prevented single control hollow glass embedded shutter comprises a shutter body, an inner frame, inner and outer operating mechanisms, a blind rotating execution mechanism, blinds, a blind rotating traction rope tensioning mechanism and a blind rotating traction rope, wherein the shutter bodyis composed of upper and lower horizontal frame tubes, left and right vertical frame tubes and inner and outer glass; the blind rotating traction rope tensioning mechanism is arranged onto a right bottom corner plug. The inward suction prevented single control hollow glass embedded shutter is characterized in that the bottom wall of one side of the upper horizontal frame tube, which faces towardsto a blind cavity, is provided with upper horizontal frame tube cavity air holes; the upward side of the left end of the horizontal plugging arm of the left upper corner plug is provided with a pressure balancing pipe fixing seat embedding cavity, a pressure balancing pipe fixing seat is arranged corresponding to the pressure balancing pipe fixing seat embedding cavity and provided with a pair ofpressure balancing pipes, the left ends of the pair of pressure balancing pipes extend out the left end surface of the horizontal plugging arm of the left upper corner plug and penetrates through sealing rubber strips to communicated with the outside, and the right ends of the pair of pressure balancing pipes extend into and are communicated with an upper horizontal frame pipe cavity. The can avoids inward suction of the inner and outer glass which is caused by thermal expansion and contraction.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a single-control hollow glass built-in shutter that can prevent glass from sucking in. Background technique [0002] The glass inhalation mentioned above is the inward deformation. 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 windows that belong to the category of sunshade hollow glass products are composed of lifting venetian blinds. This kind of windows has the following advantages self-evidently: good heat insulation can reflect the energy saving of buildings; excellent sound insulation performance can avoid the noise of the outside world. Anti-condensation and frost to ensure sufficient indoor light and reflect the desired bright effect; through the adjustm...
