The specific embodiment
Below be specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As shown in Figure 1 to Figure 3, wind-resistant roller shutter comprises casement 1, window cover 2, is installed in the parts such as the pipe crimping 3 in the window cover 2, the limit rail 4 that is arranged on casement 1 dual-side, the lower beam 5 that is horizontally installed on the curtain bottom, motor 6.
Each is fixedly connected with rail 4 on one side downwards the two ends of window cover 2, and limit rail 4 has longitudinal opening towards casement 1 one sides, and rail 4 lower ends in limit are fixedly connected with limit flange of rail plug 8, and rail 4 upper ends in limit are fixedly connected with selvage guide top plug 7, selvage guide top plug 7 casement 1 edge that can vertically stretch through.The impurity such as dust can not be entered in the limit rail 4, thereby guarantee the cleaning of limit rail inner chamber, prevent because impurity too much stops up the situation appearance that limit rail inner chamber causes casement 1 lifting difficulty.
The track of longitudinally packing in the limit rail 4, track longitudinally forms open slot, the opening part of open slot is towards casement 1 one sides, suitable for reading and the window cover 2 of open slot is connected, longitudinally lay a lead 17 in the open slot, the dual-side of casement 1 is along respectively by stretching into open slot and located lateral in lead 17 behind the opening part with the longitudinal opening of side rail 4 and open slot.
At the both sides rail 4 interior cavitys that all have vertical perforation limit rail 4, this cavity is positioned at the track outside.All be vertically installed with this wind-resistant roller shutter haulage gear in every limit rail 4 cavitys, link 9, compensating part 10, moving pulley bracket 11, connecting rod 12 and traction piece 13 in the middle of haulage gear comprises, wherein connecting rod 12 upper ends are fixed on the selvage guide top plug 7, on connecting rod 12, vertically offer a plurality of connecting hole 12a, connecting rod 12 lower ends are interted on middle link 9 and are passed connecting hole 12a and middle link 9 is connected by pin, compensating part 10 upper ends link to each other with middle link 9, and moving pulley bracket 11 is suspended on compensating part 10 lower ends.Pin is installed in connecting hole 12a places different on the connecting rod 12, adapting to the elasticity of different compensating parts 10, so that the compensating part 10 of mediate 11 of link 9 and moving pulley brackets keeps relaxed state in idle situation.Between compensating part 10 and selvage guide top plug 7, middle link 9 and connecting rod 12 are set, not only can suitably shorten the length of compensating part 10, avoid because the long elastic effect that causes of compensating part 10 length is not good enough, and convenient the installation.
Be provided with rope-winding wheel 15 at pipe crimping 3, traction piece 13 upper ends are passed selvage guide top plug 7 and are fixed on the rope-winding wheel 15.Offer roller 18 at selvage guide top plug 7, traction piece 13 runs through selvage guide top plug 7 o'clock and contacts with roller 18, and roller 18 mainly plays and guides the up or down effect of smooth sliding of traction piece 13, guarantees stability and the guidance quality of whole mechanism.When casement 1 rises or descend, by rope-winding wheel 15 can be in good order emit or draw in traction piece 13, thereby avoid traction piece 13 assorted order being wound on the pipe crimping 3 without chapter.Have fixture block 15a at rope-winding wheel 15 inwalls, offer the draw-in groove 3a of horizontally set on pipe crimping 3 outer walls, fixture block 15a fixes in draw-in groove 3a.So just rope-winding wheel 15 can be fixed on the pipe crimping 3, thereby when pipe crimping 3 rotates, drive rope-winding wheel 15 rotations and emit or draw in traction piece 13, the draw-in groove 3a that laterally offers simultaneously not only can conveniently install rope-winding wheel 15, and can adjust according to actual needs rope-winding wheel 15 and be installed in position on the pipe crimping 3.
Pulley 14 in the middle of being installed on the link 9 has two, this two pulley 14 divide one on the other be located in the middle of the inside and outside both sides of link 9, wherein in the middle of on the link 9 inboard pulley 14(namely in the middle of on the link 9 near the pulley 14 of casement 1) be positioned at another pulley 14 tops.
Being installed in pulley 14 on the limit flange of rail plug 8 has three and laterally be arranged in parallel side by side, and link 9 superolateral pulleys 14 are on the same vertical plane in the middle of wherein being positioned on the limit flange of rail plug 8 outermost pulley 14 and being installed in.Be enclosed with bottom plug lid 16 at limit flange of rail plug 8 outer peripheral faces, good looking appearance so not only, but also can play the effect of edge protection flange of rail plug 8, avoid install and use procedure in limit flange of rail plug 8 run into extraneous collision and impaired.
In the present invention, compensating part 10 is compensating spring, and other have flexible parts also can according to actual needs compensating part 10 to be changed into elastic rubber strip etc.
In the present embodiment, traction piece 13 is wire rope, this wire rope is to be made of individual wire, also can be to be twisted thigh by the multilayer steel wire, again centered by wire rope core, twist with the fingers helically wound rope by some thighs, the intensity of wire rope is high, from heavy and light, stable working, be difficult for suddenly whole root fracture, reliable operation.Other have the parts of traction function also can according to actual needs traction piece 13 to be changed into nylon rope etc., and nylon rope is to be processed through a series of by the fibre that nylon chips is made, and has advantage wear-resisting, tough and tensile and that hardness is high.
This wind-resistant roller shutter haulage gear operating principle is as follows: when rolling when casement 1 rising and by pipe crimping 3, rope-winding wheel 15 rotates under the drive of pipe crimping 3 and traction piece 13 is emitted; Meeting under the landscape condition, when manual or electronic control casement 1 descends, owing to be subjected to influenced by wind pressure wind that casement 1 is applied an active force that makes progress (namely lower beam 5 being applied an active force that makes progress), this moment, lower beam 5 tension traction pieces 13 had the trend that moves up, and rope-winding wheel 15 rotates traction piece 13 gatherings are got up under the drive of pipe crimping 3, therefore traction piece 13 two are tightly strained, broken for fear of traction piece 13, compensating part 10 is in extended state under the effect of moving pulley bracket 11, that is to say that moving pulley bracket 11 moves down under the effect of compensating part 10, thereby making originally, the traction piece 13 of overtighten relaxes, make things convenient for traction piece 13 smooth and easy movements, compensating part 10 plays compensating action here; And traction piece 13 applies a downward active force to lower beam 5 under the effect of rope-winding wheel 15, thereby balances out and make casement 1 to descend smoothly under the traction of traction piece 13 active force that wind-force applies.This wind-resistant roller shutter is possessing under the prerequisite of wind resistance, by haulage gear so that curtain when being subject to blast, can move up and down smoothly.
Specific embodiment described herein only is to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or replenish or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
