As shown in Figure 1, as wish rising blind, press " rising " key on the gauge tap panel, the rising circuit of blind is connected, and motor 4 clockwise rotates, and its output drives power transmission shaft 2, ratchet 12 rotating in same directions.As Fig. 9, ratchet 12 first dallies after certain angle, circular arc block 12-2 touches the elbow 13-1 of transmission torsional spring 13, the inner face of elbow 13-1 is postponed, transmission torsional spring 13 produces the distortion that external diameter reduces, and forms certain interval with chain guard 16 inwalls, and transmission torsional spring 13 can successfully be rotated with ratchet 12, until elbow 13-1 touches square key 15-2, then promote sprocket wheel 15 with turning.as Fig. 6, adopt bearing pin 9 to be arranged on two left sides of rolling up on cover 7, the ratchet 8 of right symmetry is subject to the pressure of spring leaf 6, embed between the ratchet 12-1 of ratchet 12, when ratchet 12 clockwise rotates with sprocket wheel 15, left pawl 8 is by left side ratchet jack-up, and the elastic force that overcomes spring leaf 6 is lifted away from left side ratchet 12-1, not hindering ratchet 12 rotates, the claw hook of the right ratchet 8 of right side ratchet 12-1 conflict simultaneously, drive right ratchet 8, volume cover 7, suspension plate 10-1 clockwise rotates jointly, make the left side of upset wire rope 10, right two ends drive respectively a left side, right two groups of upset chains 22 descend, ascending motion, driving louvre blade 29 right edge by forked link 21 descends, the left side rises on the limit, realize that namely louvre blade 29 overturns clockwise.When volume cover 7 turns an angle, when louvre blade 29 is in level, the pawl tactile bracket jacking block 14-2 in pinnacle of rightward pawl 8, inclined-plane along jacking block 14-2 slides and rotates around bearing pin 9, make ratchet 8 be lifted away from ratchet, ratchet 8, volume cover 7 no longer rotate with ratchet 12, power transmission shaft 2, and louvre blade 29 transferred level to and stopped upset this moment, and ratchet 12 still is rotated further.As Fig. 1, because of lifting chain 17 across on sprocket wheel 15 and intermeshing, lifting chain 17 1 ends are connected with small slide block 18 by bolt, the other end passes large slide block 25 and is connected with bottom dog 26 use bolts, when sprocket wheel 15 is clockwise rotated by ratchet 12 band actions, lifting chain 17 drives small slide block 18 along the raised line down sliding of gathering sill 32 inner chambers, bottom dog 26 promotes large slide block 25 along the raised line upward sliding of gathering sill 32 inner chambers, and the post 30-2 that upwarps of side hook 30 upwards lifts the rising, superimposed piecewise from bottom to top of forked link 21, louvre blade 29.In said process, be arranged on respectively on the biplate on the high Connection Block 21-4 of forked link, low Connection Block 21-5 under joint upset carrier bar 22-1, monolithic joint upset carrier bar 22-2 two ends respectively around tubular rivet 31, high Connection Block 21-4, low Connection Block 21-5 rotation, mutually folding, chimeric in two folder one modes, because high Connection Block 21-4, low Connection Block 21-5 make left and right two groups of upset chains, 22 formation heights poor, two groups of upset chains 22 can misplace folding and not interfere with each other.Can rise piecewise each louvre blade 29 until whole louvre blade 29 is folded mutually from bottom to top this moment, the up stroke limit switch auto-breaking of motor 4, motor 4 stops operating, and blind stops rising, each louvre blade sheet 29 is in level, as Figure 10 (1).
need to draw at blind, be stranded in arbitrary height, and during adjusting louver sheet 29 inclination angle, can press " stopping " key on the gauge tap panel, blind stops rising, press again " decline " key on the gauge tap panel, as Fig. 9, motor 4 outputs drive power transmission shaft 2, ratchet 12 rotates counterclockwise, contact the elbow 13-1 of transmission torsional spring 13 after circular arc block 12-2 idle running certain angle on ratchet 12, transmission torsional spring 13 reduced diameter, transmission torsional spring 13 contacts sprocket wheel square key 15-2 after rotating certain corner with circular arc block 12-2, promoting sprocket wheel 15 clockwise rotates, thereby drive upset wire rope 10, upset chain 22 rotates, drive louvre blade 29 upsets, as Fig. 6, driven volume cover 7 with clockwise rotate certain angle after by the ratchet 8 that spring leaf 6 is pressed into the ratchet teeth groove this moment, louvre blade is in plumbness, left pawl 8 contacts bracket jacking block 14-2 and is lifted away from ratchet, volume cover 7 is no longer rotated, louvre blade 29 stops upset but can continue rising, press " stopping " button as the desired location before stopping operating at volume cover 7, louvre blade 29 can be positioned required inclination angle.Continue to descend as need, as long as by " decline " button, 29 of louvre blades continue to descend.
when blind drops to the end, louvre blade 29 is adjusted to vertical closure state, realize sunshade or during to the window anti-theft security function, as Figure 10 (4), adopt normal method if any the people, when praising louvre blade 29 with hand from the bottom, as Fig. 1, louvre blade 29 drives upset chain 22 and rises, and withstand large slide block 25 by the side hook 30 that junction plate 24 drives are fixedly connected with it and jointly rise, but insert large slide block 25 and withdraw from large slide block 25 with the bottom dog 26 of lifting chain 17 engagement, the former roller bearing 27 that is blocked by the side plate 26-2 on bottom dog 26, taper liner plate 28 also breaks away from constraint, roller bearing 27 touches gathering sill 32 inwalls, taper liner plate 28 1 sides lean roller bearing 27, opposite side leans the skew back face 25-1 of large slide block 25, when lifting chain 17, when large slide block 25 rises, driving taper liner plate 28 rises, taper liner plate 28 presses to gathering sill 32 inwalls and more and more tighter with roller bearing 27, reach the antitheft effect of the improper rising braking of blind, meanwhile, when lifting chain 17 rises, band movable sprocket 15 rotates, square key 15-2 on sprocket wheel 15 touches the elbow 13-1 of transmission torsional spring 13 from the outside, the outside of elbow 13-1 is postponed, make transmission torsional spring 13 that the distortion that external diameter increases occur, transmission torsional spring 13 external diameters push against chain guard 16 inwalls, produce the rotation of larger frictional force prevention sprocket wheel 15.The present invention adopts the transmission torsional spring 13 of two same parameters to be arranged in juxtaposition, and can improve the reliability of the above-mentioned irreversible kind of drive.
Because elastic collar 11 openings, circle body are slightly more than the external diameter that half-turn, its internal diameter are slightly less than circular trough 12-3 on ratchet 12 ratchets, after inserting circular trough 12-3, elastic collar 11 can block circular trough 12-3 external diameter, and make and produce certain frictional force between the two.At louvre blade between 29 rising stages, when motor 4 driving pawls 12, volume cover 7, ratchet 8 push up bracket jacking block 14-2 to a direction rotation, the ratchet 8 that originally hooked ratchet is lifted away from ratchet, volume cover 7, ratchet 8 do not rotate, and ratchet 12 still is rotated further, and drive elastic collar 11 and synchronously rotates, the end jacking another ratchet 8 of elastic collar 11 is lifted away from ratchet, and ratchet 8 no longer is lifted away to reciprocation cycle, be pressed into ratchet and send and affect " clatter, clatter, clatter---" noise that the product use is felt.
Fill high density foaming polyurethane 29-3 in the cavity of louvre blade 29 of the present invention, can increase the flexural strength of louvre blade 29, namely increased the wind loading rating of blind.Under the control of above-mentioned each transmission mechanism, in blind, each louvre blade 29 can move according to operational order.When blind decline of the present invention, when launching, can handle upset chain 22 drive louvre blades 29 and rotate around forked link 21, the mutual rotation of each louvre blade 29 separated, and occurs the gap between sheet, can realize ventilation, daylighting, and keep the good visual field; When adjusting louver sheet 29 was vertical, the rake tooth 29-2 at adjacent louvre blade 29 two ends, cross section is intermeshing, and was tight-closed to window opening, makes the existing good wind loading rating of this blind, but air lock external noise again also has insulation, anti-theft feature.
