Further, described support bar has many, connects by wire rope between the adjacent support bar, and support bar foremost is connected with described roller shutter end.
Further, described support bar is i iron.
Further, described roller shutter both sides are respectively equipped with bearing bracket stand, and described bearing bracket stand is provided with the first sliding bearing, and the axle center of described the first sliding bearing in vertical state; Described the first sliding bearing embeds in the first chute of described the first guide rail.
Further, described the first guide rail also is provided with guide groove, and the both sides of described roller shutter are arranged in described guide groove, is provided with the first spring bearing between described roller shutter both sides and the guide groove, and described the first spring bearing is arranged on described the first guide rail.
Further, described support bar two ends are respectively equipped with bearing bracket stand, and described bearing bracket stand is provided with the second sliding bearing, and the axle center of described the second sliding bearing in vertical state; Described the second sliding bearing embeds in the second chute of described the second guide rail.
Further, the top of described support bar also is provided with the second spring bearing, and described the second spring bearing is resisted against the bottom of described roller shutter.
Further, described the second spring bearing has three, is arranged at respectively two ends and the middle part of described support bar.
Further, the below of described support bar also is provided with the 3rd spring bearing, and described the 3rd spring bearing is resisted against on described the second guide rail.
Horizontal fire curtain of the present utility model is by arranging support bar below roller shutter, support the weight of roller shutter by support bar, so the middle part of roller shutter can be not sagging, thus roller shutter can be done wider, can adapt to more application scenario.And horizontal fire-proof rolling shutter structure intensity of the present utility model is high, safe and reliable.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, horizontal fire curtain of the present invention comprises roller shutter 2 and the first guide rail 5, and roller shutter 2 both sides are arranged at respectively the first guide rail 5, and roller shutter 2 belows are provided with support bar 4, and support bar 4 two ends are arranged at the second guide rail 10.Support bar 4 has many, connects by wire rope 3 between the adjacent support bar 4, and support bar 4 foremost is connected with roller shutter 2 ends.Support bar 4 is preferably i iron.
As shown in Figure 2, roller shutter 2 both sides are respectively equipped with bearing bracket stand 9, and the axle center that bearing bracket stand 9 is provided with the first sliding bearing 8, the first sliding bearings 8 in vertical state; The first sliding bearing 8 embeds in the first chute of the first guide rail 57.The first guide rail 5 also is provided with guide groove 15, and the both sides of roller shutter 2 are arranged in guide groove 15, is provided with the first spring bearing 6, the first spring bearings 6 between roller shutter 2 both sides and the guide groove 15 and is arranged on the first guide rail 5.
Support bar 4 two ends are respectively equipped with bearing bracket stand, and the axle center that bearing bracket stand is provided with the second sliding bearing 11, the second sliding bearings 11 in vertical state; The second sliding bearing 11 embeds in the second chute 12 of the second guide rail 10.The top of support bar 4 also is provided with the bottom that the second spring bearing 14, the second spring bearings 14 are resisted against roller shutter 2.The second spring bearing 14 has three, is arranged at respectively two ends and the middle part of support bar 4.Certainly, the second spring bearing 14 also can have more, is evenly arranged in support bar 4 tops, to reach better supporting role.The below of support bar 4 also is provided with the 3rd spring bearing 13, the three spring bearings 13 and is resisted against on the second guide rail 10.
Under normal circumstances, roller shutter 2 rollings are in roller shutter case 1, and support bar 4 is collected in roller shutter 2 belows near roller shutter case 1 place.In the time of need to opening roller shutter, driving roller shutter 2 by shutter 1 launches, first support bar that roller shutter 2 can drive foremost together moves, when the wire rope 3 between first support bar and second support bar collapses when tight, first support bar drives second support bar by wire rope 3 and together slides, in like manner, each support bar that can spur successively the back slides, last support bar 4 is evenly arranged in the below of roller shutter 2, can play good supporting role to roller shutter 2, thereby can do roller shutter 2 widelyr, to adapt to different application scenarios.
When needs are packed up roller shutter, drive roller shutter 2 rollings by shutter, first support bar that roller shutter 2 can drive foremost together moves, when first support bar touches second support bar, first support bar promotes second support bar and together slides, in like manner, each support bar that can promote successively the back slides, and last support bar is collected in roller shutter 2 belows near roller shutter case 1 place.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
