Example 1

Referring to fig. 1-4, the present embodiment provides a curtain with a good rolling effect, including a winding reel 1 and a cloth curtain 3 wound on the winding reel 1, one end of the winding reel 1 is connected with a rotation driving mechanism, the rotation driving mechanism includes a motor 4 and a rotating shaft 6 installed at an output end of the motor 4, one end of the rotating shaft 6, far away from the motor 4, passes through a support 7 and is fixedly connected to the winding reel 1, the support 7 is provided with two sets of mutually opposite supports, the two sets of supports 7 are both fixed on a wall, the upper portion of the winding reel 1 is further provided with a pressing strip 2 for pressing the cloth curtain 3 onto the winding reel 1, and the bottoms of two ends of the pressing strip 2 are provided with a lifting mechanism driven by the rotating.

When the cloth curtain 3 needs to be lifted, the motor 4 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the winding shaft 1 to rotate, so that the cloth curtain is wound on the winding shaft 1, and in the process, the rotating shaft 6 controls the pressing strip 2 to be close to the winding shaft 1 through the lifting mechanism, so that the cloth curtain 3 can be tightly wound on the winding shaft 1 in the winding process; through the reversal of motor 4, realize the decline of cloth curtain 3 in order to seal the window, at this in-process, pivot 6 passes through elevating system control layering 2 and keeps away from the spool 1 to increase the clearance between layering 2 and the spool 1, avoid layering 2 to hinder the expansion of cloth curtain 3.

Elevating system includes fixed mounting at the epaxial first bevel gear 13 of pivot 6 and the second bevel gear 12 with first bevel gear 13 meshing, second bevel gear 12 one side fixedly connected with rotary drum 11, rotary drum 11 passes fixed plate 10, and rotary drum 11 and fixed plate 10 normal running fit, and the inside threaded connection of rotary drum 11 has lifter 9, the one end fixed connection to layering 2 bottom of rotary drum 11 is kept away from to lifter 9, fixed plate 10 fixed connection is in support 7 side.

When the rotating shaft 6 rotates, the first bevel gear 13 is driven to rotate, the first bevel gear 13 drives the second bevel gear 12 to rotate, and the second bevel gear 12 drives the rotating drum 11 to rotate, so that the lifting rod 9 is driven to lift along the rotating drum 11, and the approaching and the separating of the pressing strip 2 and the winding shaft 1 are realized.

The outer side of the lower end of the lifting rod 9 is provided with an external thread, an internal thread matched with the external thread is arranged inside the rotary drum 11, and the bottom of the lifting rod 9 is connected with a spring 17 through a rotating component.

When the motor 4 drives the rotating shaft 6 to rotate to drive the cloth curtain 3 to be unfolded, the lifting rod 9 is transmitted to the upper part of the rotary drum 11 by the threads, so that the lifting rod 9 is disengaged from the rotary drum 11 by the threads, and at the moment, the lifting rod 9 cannot be continuously moved upwards by the rotation of the rotary drum 11; when the motor 4 drives the rotating shaft 6 to rotate to drive the cloth curtain 3 to be retracted, the rotating shaft 6 rotates reversely to drive the rotating drum 11 to rotate reversely, the lifting rod 9 is pulled by the spring 17 to be in threaded fit with the rotating drum 11 again, and then the rotating drum 11 drives the lifting rod 9 to move downwards. Until the lifting rod 9 moves to the bottom of the rotary drum 11 and is disengaged from the rotary drum 11 through thread fit, the pressing strip 2 keeps a certain distance from the winding shaft 1 at the moment, and the cloth curtain 3 is pressed tightly; when the cloth curtain 3 needs to be unfolded again, the lifting rod 9 is driven to move upwards by the tension of the spring 17 to be matched with the internal thread of the rotary drum 11 again.

And a sliding groove 8 matched with the pressing strip 2 is arranged on the bracket 7.

The curtain 4 is made of PET material and has the advantages of good shading effect and good ultraviolet-proof effect.

The working principle of the embodiment is as follows: when the cloth curtain 3 needs to be lifted, the motor 4 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the winding shaft 1 to rotate, so that the cloth curtain is wound on the winding shaft 1, and in the process, the rotating shaft 6 controls the pressing strip 2 to be close to the winding shaft 1 through the lifting mechanism, so that the cloth curtain 3 can be tightly wound on the winding shaft 1 in the winding process; through the reversal of motor 4, realize the decline of cloth curtain 3 in order to seal the window, at this in-process, pivot 6 passes through elevating system control layering 2 and keeps away from the spool 1 to increase the clearance between layering 2 and the spool 1, avoid layering 2 to hinder the expansion of cloth curtain 3.

Example 2

Referring to fig. 1, in the present embodiment, compared to embodiment 1, a bottom plate 5 is disposed at the bottom of the cloth curtain 3, and the weight of the cloth curtain 3 is increased by the disposition of the bottom plate 5, so that the cloth curtain 3 can keep straight when being unfolded.

The embodiment of the utility model provides an in, through the setting of layering 2, when the rolling of cloth curtain 3, make cloth curtain 3 can hug closely reel 1, avoided the fluffy winding of cloth curtain 3 on reel 1, solved the problem of the follow-up difficulty of expanding of cloth curtain 3, prolonged the life of (window) curtain.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
