摘要： An automatic clutch type chain pulling mechanism for a motor rolling door for releasing the brake and winding up the door curtain by pulling the chain during electricity cutoff. The chain pulling mechanism is enclosed in a housing and is provided on the rotating shaft of the motor from the outside end inward with a drive block fixed on the rotating shaft of the motor which forms along its circumference a plurality of lugs protruding radially outward, an intermediate disk having an elongated radial slot and formed with a raised circular flange on its circumference with a friction clamping ring inserted within the inner surface of the flange, and a releasing rod mechanism. The releasing rod mechanism includes a brake releasing rod with one end fixed with a pin inserted into the elongated slot and the other end pivoted and having a pair of wing plates inclined upward fixed on the pivoted end for pushing an intermediate lever. The intermediate lever having one end pivoted acts upon an actuating lever fixed integrally with a cam pin of the drum brake assembly. The chain sprocket can be pulled by a chain via external force and is rotatably mounted on the housing. On the inner surface of the chain sprocket, there is a pivotally mounted triggering plate acted upon by a leaf spring, the plate has two lower sides formed with two branch arms for actuating the fixed drive block and a protruding actuating pin fixed on the lower middle part for actuating the friction clamping ring.

摘要： A bi-directional clutch type chain pulling device for rolling doors for releasing the brake and rolling the door up by pulling the chain at an arbitrary direction has a chain sprocket which can be pulled by external force and which is pivoted thereon with a spring acted triggering plate, the sides of which are formed with a pair of branch legs and a projected actuating pin which is secured at an intermediate portion. A linkage pin is inserted into the rotating shaft and projects out. An intermediate disk has radially an elongate slide groove and has in the intermediate portion a cylinder having an inner hole, on the inner surface of the hole being provided with a friction ring which can be actuated via the actuating pin. A release lever mechanism including a brake release lever is provided having a pin secured to one end for insertion into the elongate slide groove, the other end being pivoted and having a pair of upwardly inclined wing plates secured to it for acting on an actuating lever fixed integrally with the cam pin of a drum brake assembly via an intermediate lever pivoted at one end.

摘要： An apparatus for preventing a motor rolling door from falling includes a wedge shaped sliding plate located at one side of a driven sprocket, which is biased away from the driven sprocket by means of two actuating rods forced by two springs. Two rollers at the outer ends of two actuating rods push against the inner surfaces of the upper and lower stringers of the drive chain to keep the sliding plate away from the driven sprocket. When the drive chain is broken, the two actuating rods extend outward due to the action of the springs, and bias the wedge sliding plate toward the driven sprocket to engage with the driven sprocket, so that the rolling door is prevented from falling by its own weight.
摘要翻译：一种用于防止电动机卷帘门掉落的装置包括位于从动链轮一侧的楔形滑动板，该楔形滑动板借助于被两个弹簧强制的两个致动杆偏压于从动链轮。两个致动杆的外端的两个滚轮推动驱动链的上下桁条的内表面，以使滑板远离被动链轮。当驱动链条断裂时，两个致动杆由于弹簧的作用而向外延伸，并且将楔形滑板偏压到从动链轮以与从动链轮接合，从而防止滚动门自身落下重量。
