The specific embodiment

Consult Fig. 1, shown in Figure 2, a kind of scrolling torsion balance formula iron rolling door mainly comprises rolling door 1, motor 2, hinge 3, pulley 4, counterweight 5, cable wire 6, guard shield 7, cable wire dish 8, tubular axis 9, belt pulley 10, hinge rolling disk 11 etc.; Described rolling door 1 is a prior art, and the tubular axis 9 on its top drives rolling doors 1 opening and closing by the output shaft of belt pulley 10 and V-belt connection motor 2 by motor 2; The utility model is set up a cable wire dish 8 and a hinge rolling disk 11 on tubular axis 9, cable wire dish 8 is same axle center with hinge rolling disk 11, cable wire 6 in the cable wire dish 8 is extended to pulley 4 with horizontal direction, and through the vertical and lower link counterweight 5 of pulley 4, motor 2 and pulley 4 are arranged in the guard shield 7, be provided with hinge 3 in the hinge rolling disk 11, hinge 3 extends downwards; Described counterweight 5 is a brick-shaped, and by vertically stacked about the several piece, the counterweight 5 on top connects with cable wire 6; Motor 2 is selected for use electrical load and the highly sensitive miniature motor of rotation speed change, adopts the photoelectric control switch double insurance, and the iron rolling door in making dynamically can stop immediately in case of just slightly stopping.Also motor 2 can be set, adopt manual operation hinge 3.

Consult Fig. 3, Fig. 4, shown in Figure 5, it is good that described counterweight 5 is selected for use than the ferrous material great, that volume is little, as castiron casting fragment of brick, each piece counterweight 5 is made of first half 501 and latter half of 502, be provided with two semicircle elongated slots 504 at first half 501 and the vertical middle and upper part of latter half of 502 apposition positions, pass to the plane, top, the bottom is provided with two semicircle dovetail grooves 505, pass to the baseplane, semicircle elongated slot 504 is concentric with semicircle dovetail groove 505; First half 501 is provided with two cross through hole 506, latter half of 502 are provided with two horizontal screws 507, through hole 506 is concentric with screw 507, by interior hexagonal flat head bolt 508 first half 501 is connected with latter half of 502, and the outside is fastening by steel disc belt tensioner 503; The counterweight 5 on described top is provided with cable wire hole 509.

Consult Fig. 6, shown in Figure 7, described counterweight is about in the of 5 when superimposed, connect by slip round steel bar 510, the lower end of slip round steel bar 510 is arranged in the semicircle elongated slot 504 of following counterweight 5, and the upper end of slip round steel bar 510 is arranged in the semicircle dovetail groove 505 of top counterweight 5, slip round steel bar 510 can slide up and down in semicircle elongated slot 504, realize the driving fit up and down or the extension of counterweight 5, when two counterweights were superimposed about in the of 5, its spacing was zero, when two counterweights 5 drew high up and down, its spacing was 50mm.

Consult shown in Figure 8, in the process that rolling door 1 is closed under the drive of motor 2 or manual hinge 3, the cable wire 6 that is arranged in the cable wire dish 8 improves 50mm through the counterweight 5 that pulley 4 drives the top, upwards slide in counterweight 5 by slip round steel bar 510 simultaneously, make counterweight 5 next counterweight 5 of drive on top improve 50mm again, by that analogy, until the counterweight 5 of bottom 50mm overhead, making all, stacked counterweights 5 vertically draw high.

Consult shown in Figure 9ly, in like manner, in the process that rolling door 1 is opened, the counterweight 5 of bottom is landed earlier, and all the other counterweights 5 stack one by one, till the counterweight 5 on top is transferred.

Counterweight 5 of the present utility model stretches the diameter decision of height by cable wire dish 8, reaches the scrolling torsion balance by increase and decrease counterweight 5, offsets rolling door 1 and closes and open the scrolling torsion of continuous variation.
