Description

一种卷帘的减速机构 技术领域  TECHNICAL FIELD
本实用新型涉及一种卷帘的改进机构。  The utility model relates to an improved mechanism of a roller blind.
背景技术 Background technique
现有的卷帘上都要装置一减速机构， 以减低卷帘收卷窗帘时 的收卷速度， 避免窗帘收卷时， 因收卷速度过高而对卷帘产生冲 击， 损坏卷帘机构， 此种减速机构主要由变速机构、 重锤、 圆管 构成， 变速机构将卷帘转动速度转换成高速转动， 带动重锤也高 速转动， 在转动离心力的作用下， 重锤张开， 并紧压着圆管内壁， 重锥与圆管内壁间的摩擦力减緩了卷帘的转速， 从而达到减速的 目的。 此种减速机构由于是机械式的， 因此存在以下缺点： 1、 变 速机构的工作， 会产生很大的噪音， 污染高品位的、 安静的使用 环境； 2、 重锤与圆管间的相对的摩擦运动， 对圆管或重锤产生严 重的磨损， 使重锤与圆管间的摩擦力逐渐减少， 从而使减速机构 逐渐丧失减速的功效； 3、 由于重锤与圆管间摩擦力的大小由卷帘 的转速决定， 卷帘加速度对摩擦力几乎没有影响， 而卷帘收 时 对卷帘的冲击往往是加速度， 因此， 此种减速机构不能很好地防 止卷帘快要完全收卷时对卷帘的冲击。  A reduction mechanism is installed on the existing roller blind to reduce the rolling speed when the roller blind rolls the curtain, so as to prevent the roller blind from being impacted due to the high rolling speed when the curtain is rolled. This type of reduction mechanism is mainly composed of a speed change mechanism, a weight, and a round tube. The speed change mechanism converts the speed of the roller blind into high speed rotation, which drives the weight to rotate at a high speed. Under the action of the rotating centrifugal force, the weight is opened and pressed. The frictional force between the heavy cone and the inner wall of the round pipe slows down the speed of the roller blind against the inner wall of the round pipe, thereby achieving the purpose of deceleration. Because this type of speed reduction mechanism is mechanical, it has the following disadvantages: 1. The operation of the speed change mechanism will produce a lot of noise, which will pollute the high-quality and quiet use environment; 2. The relative weight between the hammer and the round pipe The friction movement causes severe wear to the round pipe or weight, which gradually reduces the friction between the weight and the round pipe, thereby gradually reducing the deceleration effect of the deceleration mechanism; 3. Because of the magnitude of the friction between the weight and the round pipe Determined by the speed of the roller shutter, the acceleration of the roller shutter has almost no effect on the frictional force, and the impact on the roller shutter when the roller shutter is retracted is often acceleration. Therefore, this type of deceleration mechanism cannot well prevent the roller shutter from being nearly Shock of the roller blind.
发明内容 Summary of the invention
本实用新型的目的在于提供一种收卷时減速机构不会产生噪 音、 减速耐用的、 能防止卷帘转速变速时对卷帘产生冲击的卷帘 的减速机构。  The purpose of the utility model is to provide a rolling speed reduction mechanism that does not generate noise during winding, and is durable in speed reduction, and can prevent the rolling speed from impacting the rolling speed when the speed of the rolling speed is changed.
本实用新型是这样实现的， 主要由密闭的桶体、 设置在密闭 桶体内的带有齿或叶片的转动体、 设置在密闭桶体内的液体、 转 动穿过桶体与转动体连接在一起的转轴构成。 使用时， 将桶体、 转轴分别与卷帘窗帘转筒、 带动卷帘窗帘转筒作收卷转动的弹簧 机构连接在一起。 卷帘做收卷动作时， 打开窗帘时已储蓄了很大 的回弹动能的弹簧带动卷帘窗帘转筒卷动， 使桶体相对于转动体 转动， 在桶体内液体对转动着的转动体上的齿或叶片的阻挡下， 降低了卷帘窗帘转筒的转动速度， 而且， 卷帘窗帘转筒的转动速 度或转动的加速度越高， 阻挡力就越大， 迫使卷帘窗帘转筒以平 緩的转速将打开的窗帘重新卷好。 The utility model is realized in such a manner, and is mainly composed of a closed barrel body, a rotating body with teeth or blades provided in the closed barrel body, a liquid provided in the closed barrel body, and the body connected to the rotating body through the barrel body and the rotating body. Rotating shaft. When in use, the barrel body and the rotating shaft are respectively connected with the roller blind curtain drum, and the spring that drives the roller blind curtain drum to be rolled and rotated. Institutions are connected together. When the roller blind rolls up, the spring that has saved a large amount of rebound kinetic energy when the curtain is opened drives the roller blind roller to roll, causing the barrel to rotate relative to the rotating body, and the liquid in the barrel against the rotating rotating body. The blocking of the upper teeth or blades reduces the rotation speed of the roller blind curtain, and the higher the rotation speed or acceleration of the roller blind curtain, the greater the blocking force is, forcing the roller blind roller to Rewind the opened curtains at a gentle speed.
这里，转轴上套接有弹簧， 弹簧的其中一端连接一连接构件。 使用时， 将桶体、 连接构件分别与卷帘窗帘转筒、 带动卷帘窗帘 转筒作收卷转动的弹簧机构连接在一起就可使用。 当卷帘窗帘转 筒作打开窗帘转动， 使连接构件带动弹簧往松开方向转动时， 由 于弹簧的松开， 使弹簧不能带动转轴转动， 这样， 减速机构就不 会对卷帘窗帘转筒的转动产生减速的作用， 当卷帘窗帘转筒作收 起窗帘转动时， 使连接构件带动弹簧往收紧方向转动时， 由于弹 簧的收紧， 使弹簧能带动转轴转动， 这样， 减速机构就会对卷帘 窗帘转筒的转动产生减速的作用， 防止卷帘窗帘转筒转速过快。  Here, a spring is sleeved on the rotating shaft, and one end of the spring is connected to a connecting member. When in use, the bucket body and the connecting member are respectively connected with the roller blind curtain drum and the spring mechanism which drives the roller blind curtain drum to roll and rotate, and then it can be used. When the roller blind roller rotates to open the curtain, the connecting member drives the spring to rotate in the loosening direction, because the spring is loosened, the spring cannot drive the rotating shaft, so that the deceleration mechanism will not affect the roller blind roller. The rotation produces a deceleration effect. When the roller blind curtain drum rotates to retract the curtain, the connecting member drives the spring to rotate in the tightening direction. Due to the tightening of the spring, the spring can drive the rotating shaft to rotate, so that the reduction mechanism will It has a decelerating effect on the rotation of the roller blind curtain and prevents the roller blind from rotating too fast.
为了方便在桶体内灌注液体， 桶体由桶身、 密封盖在桶身桶 口上的桶盖构成， 转动体上设有贯穿转动体的轴孔， 桶盖上也设 有轴孔， 转轴穿过桶盖插入转动体上的轴孔上。 灌注液体时， 先 将定量的液体放进桶身内 , 然后将转动体连同转轴放进桶身内， 由于轴孔的存在， 放进转动体时， 液体通过轴孔上涌， 并受转轴 的限制不会涌出轴孔， 而不会沿桶身内壁上涌， 防止了液体漫出 桶身外。  In order to facilitate the filling of liquid into the barrel body, the barrel body is composed of a barrel body and a barrel cover sealed on the barrel mouth. The rotating body is provided with a shaft hole penetrating the rotating body, and the barrel cover is also provided with a shaft hole through which the rotating shaft passes. The bucket cover is inserted into a shaft hole on the rotating body. When filling the liquid, first put a fixed amount of liquid into the barrel body, and then put the rotating body into the barrel body along with the rotating shaft. Due to the existence of the shaft hole, the liquid surges through the shaft hole when placed in the rotating body and is not restricted by the rotating shaft. The shaft hole will flow out, instead of swelling along the inner wall of the barrel, preventing the liquid from flowing out of the barrel.
转动体上的轴孔为非圆形， 与轴孔相配的转轴部分也是非圆 形。 这样， 转轴就能带动转动体转动。  The shaft hole on the rotating body is non-circular, and the shaft part matching the shaft hole is also non-circular. In this way, the rotating shaft can drive the rotating body to rotate.
为了防止液体沿转轴外壁溢出桶体， 转轴与桶盖的轴孔间设 有密封圈。  In order to prevent liquid from overflowing the barrel along the outer wall of the shaft, a seal ring is provided between the shaft and the shaft hole of the barrel cover.
在桶身底部的圆心处设有小圆柱， 对应小圆柱的转轴端面设 有圆柱孔， 小圆柱插入圆柱孔内。 这样， 转动体就能保证沿桶体 的圆心转动。 A small cylinder is provided at the center of the bottom of the barrel, and the end surface of the shaft corresponding to the small cylinder is provided. There are cylindrical holes, and small cylinders are inserted into the cylindrical holes. In this way, the rotating body can ensure rotation along the circle center of the barrel body.
本实用新型与已有技术相比， 具有卷帘收卷时减速机构不会 产生噪音、 减速耐用的、 能防止卷帘转速变速时对卷帘产生沖击 的优点。  Compared with the prior art, the utility model has the advantages that the deceleration mechanism does not generate noise when the roller blind is rolled up, is durable in deceleration, and can prevent the roller blind from impacting when the speed of the roller blind is changed.
