As shown in fig. 4 and 5, the pulley 10 includes a pulley body 100, pulley wheels 101, pulley roller shafts 102, and pulley sheaves 103. The pulley wheels 101 are mounted on both sides of the pulley body 100 through pulley roller shafts 102. The pulley roller 101 is mounted on a pulley roller shaft 102 by a bearing. The pulley movable pulley 103 is sleeved on the pulley roller shaft 102 and is positioned in the middle of the pulley roller 101.

The slide rail end cap 11 is mounted to the top end of the slide rail 7 by screws. The slide rail end cover comprises a slide rail end cover body 110 and a slide rail fixed pulley 111. The sliding rail fixed pulley 111 is mounted on the sliding rail end cover body 110 through the sleeve 112.

Two ends in the ejector rod 9 are respectively provided with an ejector rod pulley assembly 12. The ejector pulley assembly 12 includes an ejector pulley 121. The ejector rod pulley 121 is sleeved on the ejector rod pulley shaft 122. Both ends of the ejector roller shaft 122 are mounted on the ejector roller seat 120. The ejector rod pulley seat 120 is installed in the ejector rod 9 through a connecting piece 123.

As shown in fig. 6 and 7, a guide plate 13 is installed between the left end cover 2 and the right end cover 3. The guide plate 13 has a semicircular protrusion 130. The curtain cloth 6 is tightly attached to the outer surface of the semicircular bulge 130 so as to ensure that the plane formed by the curtain cloth 6 is always parallel to the sliding rail 7.

Two guide fixed pulleys 14 and a reversing fixed pulley 15 are respectively arranged on the left end cover 2 and the right end cover 3. The two fixed guide pulleys 14 are respectively adjacent to the rope winding wheel 46 and the rope pulling wheel 56. The reversing fixed pulley 15 is positioned at the lower end of the sliding rail 7, so that the pulley 10 can be prevented from falling off the sliding rail 7.

As shown in fig. 8, the rope 16 is mounted between rope reels 46 on the left and right sides of the outer tube 4. Both ends of the rope 16 are fixed to the rope winding wheels 46 on the left and right sides, respectively. The winding rope 16 sequentially passes through a left guide fixed pulley 14, a left reversing fixed pulley 15, a left sliding rail fixed pulley 111, a left sliding pulley movable pulley 103, two ejector rod pulleys 121 on the ejector rods, a right sliding pulley movable pulley 103, a right sliding rail fixed pulley 111, a right reversing fixed pulley 15 and a right guide fixed pulley 14 from left to right.

A rope 17 is installed between the rope sheave 57 and the pulley 10 on the same side. Both ends of the pulling rope 17 are respectively fixed on the pulling rope wheel 57 and the pulley 10. The pull rope 17 sequentially passes through the guide fixed pulley 14 and the reversing fixed pulley 15 from bottom to top.

When the curtain cloth 6 needs to be closed, a tubular motor 41 positioned in the outer tube 40 rotates positively, and the outer tube 40 is driven to rotate synchronously through a motor rotating wheel 42. The rope reel 46, which is positioned at the left and right sides of the outer tube 40 and fixedly connected with the outer tube 40, rotates in synchronization therewith. The rope winding wheel 46 rotates and starts winding the rope 16. Under the action of the winding rope 16, the pulley 10 moves upwards along the sliding rail 7, and the ejector rod 9 and the curtain cloth 6 arranged in the ejector rod 9 are pulled up.

The drum 50 rotates with the curtain 6 as it is pulled up. Simultaneously with the rotation of the spool 50, the torsion spring wheel 55 also rotates synchronously. The torsion spring 54 rotates with the torsion spring rotating wheel 55 to generate reverse resistance to the torsion spring rotating wheel 55, thereby playing a role in preventing the rotation of the coiled pipe 50. The curtain cloth 6 is pulled up by the ejector rod 9 and the winding pipe 50 has reverse resistance to the curtain cloth 6. The curtain cloth is stretched and leveled under the combined action of the pulling force and the resistance, so that the windproof capability and the attractive appearance of the curtain cloth are enhanced.

The trolley 10 moves up along the rail 7 during the lifting of the curtain 6. The pulley 10 drives the pull rope 17 to move upwards and simultaneously the pull rope wheel 57 rotates. The wrap torsion spring 58 rotates with the pull rope wheel 57 to generate reverse resistance to the pull rope wheel 57, so that the pull rope wheel 57 has reverse pulling force to the pulley 10 through the pull rope.

When the curtain cloth 6 is completely closed, the two ends of the curtain cloth 6 integrally enter the sliding rail 7, so that the rolling curtain system forms a whole, strong wind can be resisted, no light leakage exists at the edge, and the shielding effect is good.

When the curtain cloth 6 needs to be opened, the tubular motor 41 positioned in the outer tube 40 is reversed, and the outer tube 40 is driven to synchronously rotate through the motor rotating wheel 42. The rope reel 46, which is positioned at the left and right sides of the outer tube 40 and fixedly connected with the outer tube 40, rotates in synchronization therewith. The rope winding sheave 46 rotates while releasing the rope winding 16. The sled 10 also moves down with the roping 16.

Simultaneously with releasing the winding rope 16, the winding tube 50 rotates under the action of the elastic potential energy of the torsion spring 54, and the curtain cloth 6 wound on the winding tube 50 is pulled down. When the curtain 6 is fully opened, the roller tube 50 stops rotating. Since the stroke of the trolley 10 is greater than the stroke of the curtain 6, the trolley 10 has not been moved down to the initial position and the roping 16 has not been fully released. At this time, the pulley 57 is driven to rotate by the elastic potential energy of the scroll torsion spring 58, and the pulley 57 pulls the pulley 10 to move downwards through the pull rope 17. So that the trolley 10 moves down to the initial position and the roping 16 between the tracks 7 is also pulled completely into the casing 1 and hidden.

In summary, the invention has the following technical advantages:
