Compared with the prior art, the invention has the advantages that the roller shutter can be conveniently released and rolled, and the length of the roller shutter released curtain is controllable and accurate.
Description
The technical field is as follows:
the invention relates to a technology for a curtain.
Background art:
some existing curtain technologies need a resistance device whose resistance can increase with the increase of curtain kinetic energy, so as to slow down the speed of curtain motion and even stop the curtain motion, for example, a curtain rolling curtain without stay cord is generally provided with a rebounding mechanism, and because there is no resistance device to offset the rebounding force of the rebounding mechanism, the rebounding mechanism must be provided with a triggering mechanism, when in use, the curtain is pulled, so that the curtain is released from a rolling shaft, so as to open the curtain, and meanwhile, the rebounding mechanism stores the rebounding kinetic energy, once the curtain needs to be rewound to the rolling shaft, the rebounding mechanism is triggered, and the rebounding mechanism is driven by the power of rebounding energy storage to rewind the curtain to the rolling shaft. The roller shutter needs to trigger the rebound mechanism no matter the roller shutter is opened (rolled) to the position, the rolling of the rebound mechanism is stopped by triggering the stop mechanism in the rebound mechanism so that the roller shutter stops at the set position, and the roller shutter needs to be rewound for a certain and uncertain distance determined by the stop mechanism of the rebound mechanism when the rebound mechanism is triggered, so that the releasing length of the roller shutter is not accurate enough and the roller shutter is inconvenient to use.
The invention content is as follows:
the invention aims to provide a resistance device which can increase resistance along with the increase of the kinetic energy of a curtain and can slow down the movement speed of the curtain and even stop the movement of the curtain.
The invention is realized by the following steps that the connecting device comprises a screw rod with a connecting part, a pipe sleeve rotationally sleeved on the connecting part, a friction plate arranged on the connecting part and positioned in front of a pressure applying end of the pipe sleeve, a nut screwed on the screw rod, and a spring which is penetrated on the screw rod and positioned between the nut and the friction plate. One of the purposes of the invention is as follows: the invention is arranged at one end of a winding drum rolled with a curtain, a connecting part is fixed on a curtain bracket, a nut is connected with the inner cavity of the winding drum and rotates along with the rotation of the winding drum, the connecting end of a rewinding spring at the other end of the winding drum with the rewinding spring is connected on the curtain bracket, the curtain is pulled to be released from the winding drum, meanwhile, the rotating drum stores the elastic force of the rewinding spring, the nut rotating along with the rotation rotates along a screw rod and moves towards the direction of the connecting part, the spring is extruded, the extruded spring applies increased pressure on a friction sheet, the pressure applied by the friction sheet on a pipe sleeve pressing end is increased, the friction force is also increased, the curtain is prevented from being released from the winding drum, the weight of the curtain is increased along with the release of the curtain, so that the elastic force stored by the rewinding spring is partially offset, and the friction force applied by the friction sheet on the pipe sleeve pressing end and the gravity of the released curtain is greater than the gravity of the The elastic force of the rotation is stored, meanwhile, the friction force exerted by the friction plate on the pressing end of the pipe sleeve and the elastic force exerted by the rolling spring in the rotation are larger than the gravity of the released curtain, and the elastic force exerted by the rolling spring in the rotation is larger than the friction force exerted by the friction plate on the pressing end of the pipe sleeve, so that the winding drum can not release curtain cloth and can not roll the released curtain when no external force is applied, and only under the action of the external force, if the curtain is pulled downwards, the curtain can be released from the winding drum or can support the curtain to counteract the gravity of the released curtain, and the winding drum can roll the curtain which is released in the retraction mode, so that the purpose of the invention is achieved.
Here, a pressure plate is provided between the friction plate and the spring, and the pressure plate is fitted over the connecting portion and moves axially along the connecting portion. The pressure plate is adopted, so that the force application area of the spring on the friction plate is increased, the friction plate can be uniformly stressed, and the friction plate can effectively and uniformly apply friction force on the pipe sleeve pressure application end.
Compared with the prior art, the invention has the advantages that the resistance can be increased along with the increase of the kinetic energy of the curtain, and the movement speed of the curtain can be slowed down, even the movement of the curtain is stopped.
