A roller blind 4 that can be rolled up or put down by the tubular motor 1 is suspended below the tubular motor 1. Guide grooves 5 for guiding the roller blind 4 during rolling are arranged on both sides of the roller blind 4. The bottom of the roller blind 4 is provided with a bottom Beam 6. Specifically, the installation position of the bottom beam 6 generally corresponds to the lowest lowered position of the roller blind 4 , and the left and right ends of the bottom beam 6 are generally connected with the bottom of the guide groove 5 .

Bottom beam 6 left top is provided with first fixed pulley 7, and bottom beam 6 left bottom is provided with second fixed pulley 8, and bottom beam 6 right top is provided with the 3rd fixed pulley 9, and bottom beam 6 right bottom is provided with For the fourth fixed pulley 10, a left movable pulley 11 and a right movable pulley 12 arranged at intervals are arranged in the middle part of the bottom beam 6, and a spring 13 is arranged between the left movable pulley 11 and the right movable pulley 12.

The first backguy 14 is wound on the left wire reel 2, and the first backguy 14 is connected to the lower left corner of the roller blind 4 after going around the second fixed pulley 8, the left movable pulley 11, and the first fixed pulley 7 successively. It is used to control the retraction of the left side of the roller blind 4.

The right line reel 3 is used for controlling the retracting and unwinding of the right side of the roller blind 4 .

Specifically, for this program, the left side of the roller blind 4 is provided with a lifting mechanism consisting of the left wire reel 2, the first backguy 14, the second fixed pulley 8, the left moving pulley 11, and the first fixed pulley 7. The right side is provided with the lifting mechanism that is made of the second backguy 15, the 4th fixed pulley 10, the right moving pulley 12, the 3rd fixed pulley 9, in the actual operation process, through the lifting mechanism on the left side and the right side of the roller blind 4, can smoothly Realize rolling up or putting down of roller blind 4.

The rolling-up and lowering process of the roller blind 4 is described in detail below, because the actions of the left lifting mechanism and the right lifting mechanism are basically the same, and only the left lifting mechanism is used as an example for specific description below.

Roller blind 4 winding process:

When the roller blind 4 needs to be rolled up, the tubular motor 1 is started, and the tubular motor 1 gradually pulls the roller blind 4 upwards, and the roller blind 4 is wound on the tubular motor 1 in circles. Simultaneously, the left thread reel 2 slowly pays off the thread, and the first backguy 14 is released from the left thread reel 2 gradually, passes through the second fixed pulley 8, the left moving pulley 11, the first fixed pulley 7 in sequence, and is pulled up by the lower left corner of the roller blind 4 , until the roller blind 4 is rolled up by the tubular motor 1 completely.

During the winding process of the roller blind 4, since the left thread reel 2 and the tubular motor 1 rotate synchronously, if the tubular motor 1 keeps the rotational speed constant, then the left thread reel 2 pay-off speed remains basically unchanged, while the roller blind on the outer ring of the tubular motor 1 The winding speed (line speed) of 4 gradually increases with the increase of the radius of the rolling screen 4, that is to say, the unwinding speed of the first backguy 14 does not match the rising speed of the rolling screen 4, in view of this, this paper The invention has specially designed the guiding and compensating of backguy by the system that spring 13, left movable pulley 11, right movable pulley 12 constitute.

In the early stage of rolling up the roller blind 4, the unwinding speed of the first backguy 14 is greater than the rising speed of the roller blind 4. At this time, the spring 13 shrinks, and the extra length of the first backguy 14 is compensated by the shrinkage of the spring 13; In the mid-rolling stage, when the unwinding speed of the first pull wire 14 is equal to the rising speed of the roller blind 4, the spring 13 no longer shrinks and reaches an equilibrium point; When the ascent speed is higher, the spring 13 is elongated, and the elongated length of the spring 13 compensates for the excess speed of the roller blind 4.

In this way, through the above process, the effective winding of the roller blind 4 can be conveniently realized, and at the same time, situations such as thread jamming and crash caused by too long or too short threads can be avoided.

The process of putting down the roller blind 4 (unrolling):

When the roller blind 4 of the present invention needs to be put down, the tubular motor 1 is started, and the tubular motor 1 drives the left wire reel 2 and the right wire reel 3 to rotate, and when the left wire reel 2 and the right wire reel 3 rotate, they start to take up the wires, thereby driving the first The pull wire 14 and the second pull wire 15 simultaneously pull the lower left corner and the lower right corner of the roller blind 4 to move downward, and the roller blind 4 is gradually put down.

In this process, when the roller blind 4 is put down in the early stage, the take-up speed of the first backguy 14 is lower than the descending speed of the roller blind 4. At this time, the spring 13 is elongated, and the take-up length of the first backguy 14 plus the elongated length of the spring 13 It is equal to the lowering length of the roller blind 4; in the middle period when the roller blind 4 is put down, when the take-up speed of the first backguy 14 is equal to the descending speed of the roller blind 4, the spring 13 is no longer elongated and reaches an equilibrium point; When the take-up speed of a backguy 14 is greater than the descending speed of the roller shade 4, the spring 13 is compressed, and the compressed length of the spring 13 plus the lowering length of the roller shade 4 is equal to the take-up length of the first backguy 14. In this way, through the above process, the effective lowering of the roller blind 4 can be realized conveniently.

When the roller shutter provided by the present invention is lowered, it no longer needs to rely on the weight of the roller blind itself, but relies on the ingeniously designed lifting mechanism to pull it, which can effectively avoid the situation that the roller shutter cannot be unwound smoothly when it is not vertically arranged.

In this embodiment, in order to further facilitate the pulling of the roller blind 4 and avoid breakage of the pull wires, both the first pull wire 14 and the second pull wire 15 are preferably steel ropes.

In this embodiment, in order to further facilitate the movement of the first pull wire 14 and the second pull wire 15 according to the prescribed trajectory when taking up and releasing the wires, preferably, the connection between the left wire reel 2 and the guide groove 5 on the left side of the roller blind 4 A left guide wheel 16 is disposed between them, and the left guide wheel 16 is used for guiding the first stay wire 14 between the left wire reel 2 and the left guide groove 5 of the roller blind 4 . A right wire guide wheel 17 is arranged between the right wire reel 3 and the guide groove 5 on the right side of the roller blind 4, and the right wire guide wheel 17 is used for the second backguy 15 to move between the right wire reel 3 and the right wire reel 3. Guide between the guide grooves 5 on the right side of the roller blind 4.

In this embodiment, in order to further ensure that the supplementary amount of the spring 13 to both sides is equal, the middle part of the spring 13 and the middle part of the bottom beam 6 are fixedly connected by bolts 18 .
