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...

Problems solved by technology

However, this measure will cause an alternative problem of focusing on one thing and losing the other. The so-called focus on this means that it can ensure that the entire outer slider and the surface of the inner glass form a good rolling pair, that is, to ensure that the outer slider slides freely. The so-called loss of the other means that due to The position of the upper and lower rollers of the outer slider is high, so it is easy to make the entire outer slider high at both ends and low in the middle and cause the outer slider to deform or even break; Concave, and the mouth of the concave is facing left or right (that is, not facing the inner glass), so external dust and foreign matter can easily invade the sliding hook matching groove of the external controller, which will affect the sliding of the external controller. The shape of the guide rail of the outer manipulator whose cross-section is in the aforementioned concave shape is rigid, which affects the visibility to a certain extent, and because the sliding hook of the outer manipulator will shake in the matching groove of the outer manipulator sliding hook, the amount of shaking will be enlarged When the outer manipulator is moved up and down, the straight line or longitudinal axis of the outer manipulator will be poorly maintained, which will affect the lifting of the venetian blind and the flipping of the curtains, and because the guide rail of the outer manipulator only has the function of sliding the outer manipulator, the function Relatively monotonous; Sixth, because the blind lifting traction rope needs to pass (that is, be placed) on the traction rope redirection pulley of the blind lifting traction rope redirecting pulley set at the upper right corner of the form, so the lifting and lowering of the blinds The outer control mechanism of the traction rope drives the movement of the inner control mechanism...
