detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1-7 show a kind of a kind of embodiment of upper folded with falling proof device of the present invention: comprise the track that left and right arranges, between two tracks, be provided with from top to bottom door leaf 1, multiple middle door leafs 2 and lower door leaf 3, be connected with support 4 and support bar 5 in the upper end of two tracks, one end of support bar 5 is connected on support 4, the other end is connected on the track of support 4 lower ends, on support 4, be provided with transmission mechanism, track is connected with body of wall by fixture of the rail 6, both sides at lower door leaf 3 are connected with thrust slide 8 by junction plate 7, be provided with clamping groove plate 10 and protruding plate 9 in the inner side of fixture of the rail 6, clamping groove plate 10 is oppositely arranged with protruding plate 9, between upper door leaf 1 and body of wall, be provided with weather strip, thrust slide 8 comprises slide 11 and axle sleeve 12, on institute's axle sleeve 12, overlap dangle locator 13 and connector 14, connector 14 lower ends are connected with spring, spring is by vertical portion and V-type portion, one end of V-type portion is fixed on a side of locator 13 lower ends of dangling by the first rivet 19, be connected with roller 16 in the first rivet 19 lower ends, be fixed on the opposite side of locator 13 lower ends of dangling by the second rivet 20 at the other end of V-type portion, at the other bolt that is provided with in the bottom of V-type portion, on clamping groove plate 10, be evenly provided with multiple slotted eyes 17, on protruding plate 9, be evenly provided with multiple cambered surface protuberances 18, and slotted eye 17 setting corresponding to cambered surface protuberance 18.
Between upper door leaf and upper truss, between upper door leaf and middle door leaf, between middle door leaf and middle door leaf, be equipped with weather strip between middle door leaf and lower door leaf.
After reducing motor starts, the single sprocket chain on the bracket component of left and right drives the sprocket rotation of double chain wheel inner side by closed loop chain, and the sprocket wheel in its outside drives upper, middle and lower door leaf parts operation by open-loop chain; At door leaf upwards in running, open-loop chain on the door leaf parts of upper, middle and lower separates chain by the chain stripper on bracket component with the sprocket wheel in double chain wheel outside, respectively open-loop chain is hung up chain by chain guide, thereby prevent that open-loop chain is wound around on sprocket wheel; Equally, in the downward running of door leaf, the open-loop chain on the door leaf parts of upper, middle and lower prevents that by the effect of the guide chain plate on bracket component chain from departing from from the sprocket wheel in double chain wheel outside.Under normal circumstances, the operation of door is at the uniform velocity, stably.In the time that chain ruptures suddenly; door produces acceleration, and now the roller on thrust slide and the projecting surface on protruding plate produce and beat, and drives the locator beat that dangles under the effect of spring; the locator opposite side that makes to dangle enters in the slotted eye of clamping groove plate, thereby shutter is no longer toward falling.
The present invention makes folded door operation more smooth, and longer service life prevents that it from falling, and a guarantee door body can not fall and accidentally injure operating personnel.
