Further describe the utility model below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, the utility model by the cross section for upper side 61 is arranged, leading flank 62, the roller shutter box 6 that the section bar of downside cambered surface 63 constitutes, respectively with roller shutter box 6 left sides, right two ends are by seam grafting heavy keying fit bonded assembly left side permanent seat 2 and right permanent seat 3, be installed on the right-hand member permanent seat 3 with permanent seat 3 on the electro-motor 12 of the fixing band retarder 13 of perpendicular end face 30, be rotatably installed in the roller shutter reel 1 in the roller shutter box 6, the bearing pin 21 grafting normal-running fiies that fixedly install on the perpendicular end face 20 of the left end of reel 1 by the axis hole of the left end that fixedly installs on reel left part cover 15 and left end permanent seat 2 are connected, the right-hand member of roller shutter reel 1 is connected by the output axle key of electronic motor speed reducer 13 on the axis hole of the right-hand member that fixedly installs on reel right part cover 16 and the right-hand member permanent seat 3, driving reel 1 rotates, captive joint respectively in the lower end of left permanent seat 2 and right permanent seat 3 and to be provided with left guide rod 4 and right guide rod 4 ', be provided with heavy plumbing bar 7 at the lower end captive joint that is wound on the roller shutter 10 on the reel 1, left side at heavy plumbing bar 7, right two ends are connected with fork ring slider 71 respectively, 71 ', about the fork ring slider 71,71 ' respectively with left guide rod 4 and right guide rod 4 ' bearing fit, electro-motor 12 is furnished with control circuit device and constitutes.
As shown in Figure 4, the utility model electro-motor control circuit by double pole double throw from the direct-reverse switch circuit that resets, on its major loop, be in series with the overload protection display circuit that filament bulb RD constitutes and constitute.It is when motor M normal operation; resistance when motor is dynamic is big (480 Ω); main circuit current less (50mA); the direct current resistance of filament bulb RD very little (2 Ω); RD is not luminous; the ohmically loss in voltage of RD can be ignored; can guarantee motor M normal operation, when the top is arrived in the roller shutter rolling, motor M overload; electric current in the major loop increases (to 200mA); at this moment, the RD in the major loop is luminous, and its resistance increases (to 80 Ω) rapidly; loss in voltage on the RD also increases rapidly simultaneously; the voltage at motor M two ends is reduced greatly, and the power consumption of motor also reduces thereupon greatly, makes motor obtain overload protection; the luminous demonstration of RD can be reminded timely PTO Power Take Off switch simultaneously.
As shown in Figure 5, the utility model electro-motor control circuit by double pole double throw from the direct-reverse switch circuit that resets, on its major loop, be in series with reed switch relay JAG, be parallel with the overload protection display circuit that indicator lamp ZD constitutes at the other end of the normal opened contact of reed switch relay JAG and motor and constitute.It is when motor M normal operation, main circuit current less (50mA), the magnetic-field intensity deficiency that this electric current is produced by the dry-reed tube magnet coil is so that the action of dry-reed tube feeler, when roller shutter rolling during to the top, and motor M overload, electric current in the major loop increases (to 200mA), at this moment, the magnetic-field intensity that the reed pipe magnet coil is produced is enough to make the action of dry-reed tube feeler, disconnects normally closed contact switching normal opened contact, motor outage, indicator lamp get electroluminescence and show.The utility model electro-motor control circuit is simple in structure, and cost is low, is convenient to manufacture, and is reliable and practical.
