Blind window with built-in hollow glass

Abstract

The utility model discloses a blind window with built-in hollow glass, and belongs to the field of sunshade hollow glass products. The blind window comprises a window body, a corner seat and a venetian blind lifting traction rope transition roller, and the window body comprises an upper transverse frame pipe, a left longitudinal frame pipe, a right longitudinal frame pipe, a lower transverse framepipe, front glass and rear glass. The blind window is characterized in that the corner seat and a frame strip first corer connecting piece form an integrated structure, the upper portion of the corner seat is provided with a blind sheet overturning shaft supporting mechanism, the lower portion of the corner seat is provided with a venetian blind lifting traction rope transmission roller cavity with the bottom communicating with the outside, transition roller end stretching-in grooves are formed in the positions, corresponding to the front end and the rear end of the venetian blind lifting traction rope transition roller, of the cavity walls, opposite to each other, of the venetian blind lifting traction rope transition roller cavity, the venetian blind lifting traction rope transition roller is arranged in the venetian blind lifting traction rope transition roller cavity, and the front end and the rear end of the venetian blind lifting traction rope transition roller stretch into thetransition roller end stretching-in grooves correspondingly. According to the blind window, the consistency effect of the overall structure is improved, and the stress requirement under the conditionof a wide window body can be met; and the manufacturing and assembling efficiency is improved, the service life is ensured, and the lifting effect is ensured.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a built-in shutter of hollow glass. Background technique [0002] The built-in shutters of insulating glass have the following self-evident advantages: good heat insulation can reflect the energy saving of the building; excellent sound insulation performance can avoid the disturbance of external noise; Expected bright effect; through the adjustment of the deflection angle of the blinds, the required indoor lighting requirements can be obtained and the privacy can be protected; the venetian blinds (customarily referred to as "curtains") can be reflected excellently No-cleaning effect; ideal embellishment for buildings to improve the grade of buildings; strong impact resistance, good safety and long service life to meet the installation requirements of high-rise buildings and meet the ultimate long-term maintenance-free requirements ; It is easy ...

Problems solved by technology

[0007] Although the above-mentioned CN108825101A can fulfill the advantages of the six aspects summarized in the technical effect column of its specification, it still has the following deficiencies: First, because the corner seat and the corner connector of the frame bar (the patent is "the upper right corner connector of the frame bar) ") mating connection, so the structural stability of the two is relatively low. In the actual use process, for example, in the process of making the inner manipulator drive the curtain flipping traction rope or the venetian blind lifting traction rope as required, the corner There is a risk of large force and damage to the seat, especially when the width of the venetian blind increases with the increase of the width of the venetian blind, the force in the aforementioned action process also increases accordingly, which may cause the corner seat to be difficult to resist. Due to the large force, it is separated from the corner connectors of the frame strips, so that the lifting of the venetian blinds and the flipping of the curtains cannot be carried out; The seat is located on the right side of the corner seat in a horizontal cantilever state, and since the turning wheel that drives the turning shaft of the blind is fixed on the right end of the turning shaft of the blind, the degree of stress on the turning wheel is very fragile. When the width of the curtain increases with the width of the blinds, it is necessary to generate enough friction between the curtain flipping traction rope that drives the turning wheel and the turning wheel to force the turning wheel to move, and because the turning wheel itself is unstable (Fixed at the right end of the blind turning shaft that lacks support), so it is easy to cause both the blind turning traction rope and the turning wheel to be damaged; thirdly, because the corner seat needs to be installed on the corner seat, it is actually a transition roller for the blind lifting traction rope The traction rope reversing wheel (the patent is called "traction rope reversing roller") is used for the lifting and lowering traction rope of the blind to be connected with the inner control mechanism after being redirected by the reversing wheel, that is, the above-mentioned pull to the inner controller. However, since the cross-section of the reversing wheel is I-shaped, that is, H-shaped, the area for nesting or supporting the lifting and pulling rope of the venetian blind is limited, which limits more strands of venetian blinds to a certain extent. Although CN108825101A abandons the reversing wheel with an I-shaped cross section and adopts a roller-shaped structure for the winding sleeve of the lifting traction, due to the difference between the end faces of the two ends of the traction rope reversing roller and the corresponding two side walls of the corner seat There is a gap between them, so on the one hand, the friction of the lifting and pulling rope of the venetian blind will be intensified in the gap, and on the other hand, there is a risk of the lifting and pulling rope of the venetian blind being stuck. The former will affect the service life of the lifting and pulling rope of the venetian blind, and the latter will lead to It is impossible to raise or lower the venetian blind; Fourth, the assembled structure of the corner seat and the corner connector of the frame bar is an assembled structure, which will increase the number of molds on the one hand, and increase the workload of assembly on the other hand, which is not conducive to saving The cost is also not easy to save valuable labor resources; five, because there is no function of flipping the venetian blinds in place and when the rotation angle of the turning drum has reached the limit, the turning wheels are idling to avoid damage to the turning ropes of the blinds. And the function of the turning wheel, so it can't play a role in the turning drum arranged on the turning shaft of the curtain, the turning wheel arranged on the right end of the turning shaft of the curtain, which is used to drive the turning of the turning shaft of the blind, and the turning wheel set on the turning wheel. used to drive The effective protection function of the traction rope when the curtain panel is turned over by the runner
