As shown in Figure 1, as wish rising blind, press " rising " key on gauge tap panel, the rising circuit ON of blind, motor 4 rotates clockwise, and its output drives power transmission shaft 2, ratchet 12 rotating in same direction.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, transmission torsional spring 13 can successfully be rotated with ratchet 12 with chain guard 16 inwall, until elbow 13-1 touches square key 15-2, then promote sprocket wheel 15 with turning.As Fig. 6, bearing pin 9 is adopted 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, between the ratchet 12-1 of embedding ratchet 12, when ratchet 12 rotates clockwise with sprocket wheel 15, left pawl 8 is by left side ratchet jack-up, and the elastic force overcoming spring leaf 6 is lifted away from left side ratchet 12-1, ratchet 12 is not hindered to rotate, simultaneously right side ratchet 12-1 conflicts the claw hook of right ratchet 8, drive right ratchet 8, volume cover 7, suspension plate 10-1 rotates clockwise jointly, make a left side for upset wire rope 10, right two ends drive a left side respectively, right two groups of upset chains 22 decline, ascending motion, louvre blade 29 right edge is driven to decline by forked link 21, limit rises in left side, namely realize louvre blade 29 to overturn clockwise.When volume cover 7 turns an angle, when louvre blade 29 is in level, bracket jacking block 14-2 is touched on the pawl pinnacle of rightward pawl 8, inclined-plane along jacking block 14-2 slides and rotates around bearing pin 9, ratchet 8 is made to be lifted away from ratchet, ratchet 8, volume cover 7 no longer rotate with ratchet 12, power transmission shaft 2, and now louvre blade 29 has transferred level to and stopped upset, and ratchet 12 is still rotated further.As Fig. 1, because lifting chain 17 is across engaging each other on the sprocket wheel 15, lifting chain 17 one end is connected with small slide block 18 by bolt, the other end is connected with bolt with bottom dog 26 through large slide block 25, when sprocket wheel 15 is rotated clockwise by the action of ratchet 12 band, lifting chain 17 drives small slide block 18 along the raised line slide downward of gathering sill 32 inner chamber, bottom dog 26 promotes the raised line upward sliding of large slide block 25 along gathering sill 32 inner chamber, side hook 30 upwarp post 30-2 upwards lift forked link 21, louvre blade 29 from bottom to top piecewise rise, superimposed.In above process, be arranged on joint upset carrier bar 22-2 two ends under the biplate on forked link height Connection Block 21-4, low Connection Block 21-5 saves upset carrier bar 22-1, monolithic respectively to rotate around tubular rivet 31, high Connection Block 21-4, low Connection Block 21-5 respectively, 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 chain 22 forming position differences of height, two groups of upset chains 22 can misplace folding and not interfere with each other.Now each louvre blade 29 can be risen piecewise until all louvre blade 29 is folded mutually from bottom to top, the up stroke limit switch auto-breaking of motor 4, motor 4 stops operating, and blind stops rising, each blinds blade 29 is in level, as Figure 10 (1).
Need draw at blind, be stranded in arbitrary height, and during adjusting louver sheet 29 inclination angle, " stopping " key on gauge tap panel can be pressed, blind stops rising, press " decline " key on gauge tap panel again, as Fig. 9, motor 4 output drives power transmission shaft 2, ratchet 12 rotates counterclockwise, the elbow 13-1 of transmission torsional spring 13 is contacted 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, promote sprocket wheel 15 to rotate clockwise, thus drive upset wire rope 10, upset chain 22 rotates, louvre blade 29 is driven to overturn, as Fig. 6, now driven volume cover 7 with after rotating clockwise certain angle by the ratchet 8 that spring leaf 6 is pressed into ratchet teeth groove, louvre blade is in plumbness, left pawl 8 contacts bracket jacking block 14-2 and is lifted away from ratchet, make volume overlap 7 no longer to rotate, louvre blade 29 stops upset but can continue to rise, as the desired location before stopping operating at volume cover 7 presses " stopping " button, louvre blade 29 can be positioned required inclination angle.As continued to decline, as long as press " decline " button, louvre blade 29 continues to decline.
When blind drops to the end, louvre blade 29 adjusts to vertical closure state, realize sunshade or to window anti-theft security function time, as Figure 10 (4), normal method is adopted if any people, when praising louvre blade 29 with hand from bottom, as Fig. 1, louvre blade 29 drives upset chain 22 to rise, and drive the side hook 30 be fixedly connected with it to withstand large slide block 25 by junction plate 24 jointly to rise, but insert large slide block 25 and the bottom dog 26 engaged with lifting chain 17 exits large slide block 25, the former roller bearing 27 blocked by the side plate 26-2 on bottom dog 26, taper liner plate 28 also departs from constraint, roller bearing 27 touches gathering sill 32 inwall, taper liner plate 28 side leans 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, taper liner plate 28 is driven to rise, it is also more and more tighter that roller bearing 27 is pressed to gathering sill 32 inwall by taper liner plate 28, reach the effect that the improper braking of rising of blind is antitheft, 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 of external diameter increase occur, transmission torsional spring 13 external diameter pushes against chain guard 16 inwall, produce the rotation that larger frictional force stops 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 of elastic collar 11 opening, circle body is slightly more than half-turn, its internal diameter is slightly less than circular trough 12-3 on ratchet 12 ratchet external diameter, circular trough 12-3 external diameter can be blocked after elastic collar 11 inserts circular trough 12-3, make to produce certain frictional force between the two.Between louvre blade 29 rising stage, when motor 4 driving pawl 12, volume cover 7, ratchet 8 rotate top to bracket jacking block 14-2 to a direction, the ratchet 8 originally hooking ratchet is lifted away from ratchet, volume cover 7, ratchet 8 do not rotate, and ratchet 12 is still rotated further, and drive elastic collar 11 synchronous axial system, the end jacking another ratchet 8 of elastic collar 11 is lifted away from ratchet, ratchet 8 is no longer lifted away to reciprocation cycle, be pressed into ratchet and send affect product use sensation " clatter, clatter, clatter---" noise.
Be filled with high density foaming polyurethane 29-3 in the cavity of louvre blade 29 of the present invention, the flexural strength of louvre blade 29 can be increased, namely add the wind loading rating of blind.Under the control of above-mentioned each transmission mechanism, in blind, each louvre blade 29 can according to operational order action.When blind decline of the present invention, expansion, can handle upset chain 22 and drive louvre blade 29 to rotate around forked link 21, each louvre blade 29 rotates separation mutually, occurs gap between sheet, can realize ventilation, daylighting, and keep the good visual field; When adjusting louver sheet 29 is vertical, the rake tooth 29-2 at two ends, adjacent louvre 29 cross section engages each other, tight-closed to window opening, makes the existing good wind loading rating of this blind, again can air lock external noise, also has insulation, anti-theft feature.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
