Description
Technical field
The invention belongs to window setting technique field, relate to a kind of shutter, particularly a kind of sun blind corner assembly.
Background technology
Having more blades in shutter and be connected by rope, rope includes light modulation rope and halliard, realizes rotating vane angle by handling light modulation rope and then realizes light modulation；Blade lifting is realized by handling halliard.Blade is between two glass of hollow window, and blade can be packed up completely, and scenery covers all at one glance outside window, and shutter has attractive in appearance energy-conservation, succinctly agile advantage.Pertinent literature about shutter is also more, such as a kind of aluminum alloy doors and windows (Authorization Notice No.: CN202530981U) with louvre curtain that Chinese patent literature is recorded, and for example a kind of shutter (Authorization Notice No.: CN203430382U).
Sun blind corner assembly is the parts for connecting cross beam Yu column, and sun blind corner assembly is additionally operable to change the direction of halliard, connect light modulation rotating shaft and light modulation stay cord etc. effect.The shutter recorded such as Chinese patent literature lifts brake gear (Authorization Notice No.: CN203835225U), including casing, directive wheel and straight spur gear, directive wheel has teeth groove, and the tooth of straight spur gear embeds in teeth groove.Having elastic wing plate and gear lock groove on casing, elastic wing plate has bar shaped brake gear shaft holes, elastic wing plate inner plate surface has gear guiding skewed slot, the axle portion of straight spur gear slips in bar shaped brake gear shaft holes from gear guiding skewed slot.This shutter lifting brake gear is capable of preventing reversely naturally sliding of halliard theoretically；But there are some shortcomings in actual use, because elastic wing plate periphery has groove, the intensity of elastic wing plate is not enough, roller gear is susceptible to swing, even brake gear shaft holes from bar shaped in jump out and the phenomenon such as elastic wing plate generation fracture；When needing straight spur gear embedding gear lock groove to realize brake simultaneously, often occur that straight spur gear original place rotates, cannot move in embedding gear lock groove along the bar shaped gear shaft holes that brakes, namely there is brake effectiveness relatively low, the problems such as brake is unstable.
Summary of the invention
The present invention proposes a kind of sun blind corner assembly, and the technical problem to be solved in the present invention is how to improve the intensity of elastic wing plate and improve brake effectiveness.
Solving the technical problem that of the present invention can be realized by following technical proposal:
These sun blind corner assembly, including casing, halliard reverse wheel and brake gear, there is in casing wheel installation cavity, halliard reverse wheel and brake gear are respectively positioned in wheel installation cavity, halliard reverse wheel has the first axle part, halliard commutation portion and the first teeth portion, and the first axle part is connected with casing；The two side of wheel installation cavity all has the brake gear shaft holes having a bar shape；Described at least one sidewall of wheel installation cavity has the brake pinion mounting holes being connected with the gear shaft holes that brakes；Brake pinion mounting holes is between brake gear shaft holes and the first axle part；Brake gear has the second axle part and the second teeth portion, and the second axle part is positioned at brake gear shaft holes, and the first teeth portion is meshed with the second teeth portion；Casing has the lock groove that the second teeth portion can embed.
These sun blind corner assembly eliminates elastic wing plate, and then thoroughly avoids the problem that elastic wing plate intensity is not enough.When these sun blind corner assembly uses, brake gear is positioned at the top of halliard reverse wheel, owing to brake pinion mounting holes is connected with brake gear shaft holes, then brake gear makes the first teeth portion fully engage with the second teeth portion under gravity, improve frictional force between brake gear and halliard reverse wheel, reduce frictional force between brake gear and casing, and then ensure that halliard reverse wheel must drive brake gear to slide along brake gear shaft holes when rotating, thus it is effectively guaranteed effectiveness and the stability of brake.
In above-mentioned sun blind corner assembly, a sidewall of described wheel installation cavity has the brake pinion mounting holes being connected with the gear shaft holes that brakes；Or two sidewalls of described wheel installation cavity have the brake pinion mounting holes being connected with the gear shaft holes that brakes.
In above-mentioned sun blind corner assembly, described brake gear adopts plastics or metal to make, or the second axle part adopts metal to make, and the second teeth portion is adopted made of plastic.Effectiveness and the stability of brake is ensure that further by improving the weight of brake gear.
In above-mentioned sun blind corner assembly, described halliard commutation portion is cylindrical or polygonal column or cylindrical and lateral surface have the equally distributed groove of a plurality of circumference.
In above-mentioned sun blind corner assembly, these sun blind corner assembly also includes the upset rope winding wheel being positioned in casing, at least being fixed with a piece of dividing plate on casing, dividing plate intersects setting with the axial line of upset rope winding wheel, and the end face of dividing plate relies on mutually with upset rope winding wheel wheel face.
When these sun blind corner assembly uses, upset rope be wrapped in upset rope winding wheel on be wound around the number of turns can more than 1 enclose, the adjacent upset rope often enclosed is separated by dividing plate, avoid pulling upset after restricting, to overturn rope to slide axially along upset rope winding wheel and produce to overturn top-bottom cross phenomenon of restricting, namely avoid causing and overturn rope abrasion mutually and cause overturning the problem reduced service life of restricting, and avoid contact area between upset rope and upset rope winding wheel to reduce and cause that upset rope and upset rope winding wheel produce skidding, and then affect blade of louver window upset.
In above-mentioned sun blind corner assembly, the end face of described dividing plate is recessed circular arc.This structure is obviously effectively improved the contact area of dividing plate and upset rope winding wheel, and then reduces upset rope top-bottom cross phenomenon further.
In above-mentioned sun blind corner assembly, described casing being further opened with multiple upset rope pilot hole, partial switching rope pilot hole is distributed in the side of upset rope winding wheel, and upset rope pilot hole in another is distributed in the opposite side of upset rope winding wheel.Upset rope is from upset rope pilot hole traverse, and then avoids upset rope to slide axially along upset rope winding wheel further, reduces upset rope top-bottom cross phenomenon.
In above-mentioned sun blind corner assembly, described casing has upset rope winding wheel axis hole, the end face of described casing has and overturns the embedded groove that rope winding wheel axis hole is connected；Described dividing plate is positioned at the lower section of upset rope winding wheel.When these sun blind corner assembly uses, upset rope is wrapped on upset rope winding wheel, what upset rope connected slides and upset rope winding wheel can be produced downward pulling force, and then both it had been avoided that upset rope winding wheel was jumped out from embedded groove, the gap between upset rope winding wheel wheel face and dividing plate end face can be reduced again, and then avoid upset rope to slip over from the gap between upset rope winding wheel and dividing plate.The sun blind corner assembly of this structure also has makes shutter assemble advantage more easily.
Compared with prior art, the advantage that these sun blind corner assembly has intensity height, long service life, stable performance.These sun blind corner assembly be applied in shutter to make shutter have easy to assembly, upset rope long service life and blade flexible overturning and stable, be automatically prevented from blade tenesmus flexibly and stable performance.
