Description

Honeycomb curtain shifting device

This creation is a speed change device applied to the honeycomb curtain. Through the stop brake bushing and the reduction gear set in the speed change device, the torsional load generated by the winding controller when the honeycomb curtain is lifted is reduced, and the honeycomb curtain can be stably retracted. Rise and fall.

There are many kinds of curtains. Curtains that are pulled up and down in common are roller blinds, honeycomb curtains, etc. Taking honeycomb curtains as an example, the honeycomb curtain 1 is hung under an upper rail 2 and a rotating shaft is provided in the upper rail 2 3. A plurality of spools 4 are provided on the rotating shaft 3, and the wire ropes 5 of each spool 4 respectively extend downward to suspend the honeycomb curtain 1, and a winding controller 6 for driving the rotating shaft 3 to rotate is provided on the side of the upper rail 2 , The side of the reel controller 6 is provided with a pull rope 7, the user can pull the pull rope 7 to control the rotation of the gear set inside the reel controller 6, and the gear set sequentially drives the rotating shaft 3 and the reel 4 to rotate synchronously to retract and unwind the wire The rope 5 further drives the honeycomb curtain 1 to move up and down.

When the honeycomb curtain rises and collapses or descends to the height set by the user, its weight will cause the shaft to rotate in the reverse direction and descend and expand. Therefore, a damping spring must be installed in the winding controller to brake the shaft to stop the shaft from winding. The curtain can maintain a still state.

When the honeycomb curtain moves up and down to rest, in addition to the weight, the inertia of the falling speed is multiplied, so that the reel controller directly bears the weight and inertia of the honeycomb curtain and generates a large torque. However, the damping spring in the winding controller has a fixed elasticity coefficient, so when the honeycomb curtain is of normal size, it can still be retracted normally, but if the honeycomb curtain needs a larger area due to the installation position and the weight is heavier, it is not only easy The retractable speed of the honeycomb curtain is unstable, and it is also easy to damage the winding controller.

For example, the weight of a large honeycomb curtain is heavier, and the inertia of its movement will increase the speed of lowering. When the honeycomb curtain moves from downward to stop, its weight and inertia of movement will produce considerable torque on the winding controller. , It is easy to damage the winding controller after long time use.

In view of this, the author has accumulated many years of research and practical experience in related fields, and specially created a transmission device applied to the honeycomb curtain to improve the user's instability of retractable speed when operating the heavier honeycomb curtain. And the problem that the conventional winding controller directly bears the torsion load when the honeycomb curtain is lifted and is easily damaged.

The purpose of this creation is to provide a honeycomb curtain speed change device, which is arranged between the winding controller and the rotating shaft, which can make the honeycomb curtain rise and fall steadily, and avoid the torsion load when the honeycomb curtain rises and falls directly acting on the winding controller, extending The service life of the winding controller.

When the user controls the winding controller to drive the rotating shaft to rotate through a pull rope, the reel on the rotating shaft can be synchronously rotated to retract the cord, which in turn drives the honeycomb curtain to move up and down , Characterized by: A speed-changing device is provided between the reel controller and the rotating shaft. The speed-changing device includes a housing provided in the upper rail, a transmission rod passing through the housing and connected with the reel controller, respectively provided in the housing and connected to the A reduction gear set between the transmission rod and the rotating shaft, and a set of stop brake bushes connected to the periphery of the front end of the reduction gear set; The winding controller drives the transmission rod, the reduction gear set and the rotating shaft in sequence, and the speed of the honeycomb curtain is slowed down by the reduction gear set; when the winding controller stops, the stop brake bushing faces the front end of the reduction gear set A brake is generated on the periphery to slow down and absorb the torsion load caused by the inertia when the honeycomb curtain and the rotating shaft stop, and directly acts on the reduction gear set and the winding controller to extend the service life of the speed change device and the winding controller.

With the above structure, the speed change device is arranged between the winding controller and the rotating shaft, and bears the torsion load of the honeycomb curtain due to the weight and inertia, to avoid the torsion load of the honeycomb curtain directly acting on the reduction gear set and the winding controller of the transmission device ,Extended service life. In addition, the reduction gear set of the transmission device can slow down the rotation speed of the rotating shaft, thereby reducing the speed at which the cord drives the honeycomb curtain to rise and fall, allowing the honeycomb curtain to rise and fall gently.
