Abstract
The utility model relates to a fire-proof rolling shutter door fuse, which comprises a fuse body, a mounting board, and a steel wire rope. The fuse body and the mounting board are connected via the steel wire rope. A screw rod is arranged in a penetrating mode in a movable hole in the mounting board. A steel wire fixing block and the front end of the screw rod are fixedly connected as a whole. One end of the steel wire rope is connected with the steel wire fixing block and the other end of the steel wire rope is connected with the fuse body. One end, facing extending of the steel wire rope, of the bottom board of the fuse body is provided with a right-angle step convex upwardly. A side cover for allowing the steel wire rope to pass through on the fuse upper cover of the fuse body and abuts against the right-angle step. As the steel wire fixing block and the screw rod are fixed as a whole, interference generated between the end part of the steel wire rope and the screw rod in the case of use as the steel wire fixing block and the screw rod are separated in the prior art can be avoided, and the mechanism performance is more stable. As the side cover of the fuse upper cover at the steel wire extending end abuts against the right-angle step, deformation of the side cover can be effectively prevented and the performance is more stable.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fire resistance rolling shutter door fuse as shown in Fig. 3, Fig. 4, Fig. 5, comprises fuse bodies, mounting panel 10, steel wire rope 30, between fuse bodies and mounting panel 10, is connected by steel wire rope 30.Steel wire rope 30 is located in steel wire sheath 31, and the two ends of steel wire sheath 31 are fixed on the base plate 22 and mounting panel 10 of fuse bodies by briquetting 32 respectively.
Mounting panel 10 is provided with installing hole 11, movable span 12, screw rod 13 is located in the movable span 12 of mounting panel 10, fixation with steel wire piece 14 is connected to one with screw rod 13 front ends, steel wire rope 30 is connected with mounting panel 10 by the fixing steel wire sheath 31 of briquetting 32, steel wire rope 30 one end are connected with fixation with steel wire piece 14, and the rear end of screw rod 13 is connected with clutch 17.In the present embodiment, screw rod 13, through fixation with steel wire piece 14, is provided with lock screw 15 on fixation with steel wire piece 14, screws lock screw 15 by the installation that is fixed as one of fixation with steel wire piece 14 and screw rod 13.Fixation with steel wire piece 14 is integral type structure with screw rod 13, when use, steel wire rope 30 is the move distance of screw rod 13 to the pull distance of fixation with steel wire piece 14, overcome in prior art the interference problem of existence between fixation with steel wire piece 14 and screw rod 13, and functional reliability is higher.In order to make steel wire rope 30 more firm with being connected of fixation with steel wire piece 14, in the present embodiment, steel wire rope 30 is penetrated by the bottom surface of fixation with steel wire piece 14, pass from the side, and again penetrated by same side, finally, from the passing of relative side, ensure the connective stability of steel wire rope 30 with fixation with steel wire piece 14.
Fuse bodies comprises that base plate 22, fuse upper cover 20, slide block 24, spring, steel wire lift ring 27, fuse link 26, briquetting 32.Fuse upper cover 20 is fixed on base plate 22, and slide block 24 is sleeved in fuse upper cover 20, and spring is arranged between slide block 24 and fuse upper cover 20.Slide block 24 is provided with protruding mount pad 25 with the upper surface of fuse upper cover 20, and the two ends of fuse link 26 are installed on respectively on mount pad 25, make spring in contraction state, the movement tendency that between fuse upper cover 20 and slide block 24, maintenance separates.Steel wire rope 30 and fuse bodies are connected by the fixing steel wire sheath 31 of briquetting 32, and steel wire rope 30 other ends penetrate from the side cover 21 of fuse upper cover 20, pass and fix, and be connected with steel wire and lift and encircle 27 from the corresponding face of slide block 24.The base plate 22 of fuse bodies, one end of stretching into towards steel wire rope 30 is provided with right angle step protruding upward 23, and the side cover 21 that the fuse upper cover 20 of fuse bodies penetrates for steel wire rope 30 keeps contact with right angle step 23.Push because side cover 21 is subject to inner spring for a long time, very easily produce distortion, cause whole spring to eject, make fuse misoperation, cause whole fuse to lose efficacy.In the utility model, right angle step 23 and side cover 21 phase contacts are set, prevent that side cover 21 is subject to the extruding of spring and is out of shape.
