When hanging or removing curtains, it is necessary to climb to the track height with the help of a ladder to perform manual operation, which poses the risk of high-altitude work and is time-consuming and labor-intensive. In addition, existing pulley tracks often adopt a single slide groove design with poor single-point load-bearing capacity, which causes the track to be easily deformed. In addition, when removing traditional curtains, the curtain's lowering locking height gauge is often unable to be adjusted according to the user's height, and the locking height is uncontrollable.

[0030] In this embodiment, specifically: the outer ring of the sliding ring 204 is fixedly connected with a stopper 205, and the stopper 205 is symmetrically provided in two groups, and the annular groove 206 is provided between the two groups of stoppers 205;

[0031] In this embodiment, specifically: a connecting ring 208 is fixedly installed on one end of the lifting rope 207 away from the annular groove 206, and a lock buckle 209 is fixedly connected to the lower side of the connecting ring 208, and the lock buckle 209 is detachably connected to a fixing ring 211;

[0032] In this embodiment, specifically: one side of the lock buckle 209 is rotatably connected to the hinge column 210 via a rotating shaft, and a torsion spring 109 is provided on the rotating shaft provided on the lock buckle 209;

[0033] In this embodiment, specifically: a curtain body 212 is fixedly mounted on the lower side of the fixing ring 211, and a second connecting post 213 is fixedly connected to the end of the track 201 away from the first fixed end 101, and the end of the second connecting post 213 away from the track 201 is rotatably connected to the second fixed end 214, and the second fixed end 214 is fixed to the wall by screws;

[0034] In this embodiment, specifically: four groups of slide grooves 202 are provided, and each group of slide grooves 202 is provided with a roller 203, multiple groups of sliding rings 204 are provided, and each group of sliding rings 204 is provided with an annular groove 206 on the outer ring thereof is connected with a lifting rope 207.

[0035] Working principle or structural principle: When in use, the first fixed end 101 and the second connecting column 213 are fixed to the wall by screws. When the curtain body 212 needs to be removed for cleaning, the bead rope 106 is manually pulled, and the bead rope 106 drives the gear 107 to rotate. When the gear 107 rotates, the teeth of the outer ring squeeze the clamping teeth 108 to move upward. When the clamping teeth 108 move upward, the extrusion spring 109 and the guide column 110 contract, so that the clamping teeth 108 are away from the tooth groove of the gear 107. The bead rope 106 is continuously pulled, and the gear 107 is continuously rotated, thereby driving the rotating shaft 102 to rotate on the first fixed end 101. The rotation of the rotating shaft 102 drives the first connecting column 103 fixed on one side to rotate synchronously, thereby driving the track 201 to rotate;

[0036] When the track 201 rotates, the track 201 drives the second connecting column 213 fixed at one end to rotate, so that the second connecting column 213 rotates on one side of the second fixed end 214, and the outer ring of the track 201 is provided with four groups of slide grooves 202, and each group of slide grooves 202 is connected to a roller 203, and the roller 203 is fixed on the inner ring of the sliding ring 204, thereby driving the sliding ring 204 to rotate. When the sliding ring 204 rotates, one end of the lifting rope 207 wound around the annular groove 206 provided on the outer ring of the sliding ring 204 moves downward, and stoppers 205 are fixedly installed on both sides of the outer ring of the sliding ring 204, and the stoppers 205 can prevent the lifting rope 207 from falling off from the annular groove 206;

[0037] One end of the lifting rope 207 continues to move downward, causing the curtain body 212 to move downward accordingly. When the curtain body 212 moves to the chest of the user, the pulling rope 106 is stopped, and the clamping teeth 108 are clamped into the tooth groove on the gear 107 by the rebound force of the spring 109, so that the height of the curtain body 212 is fixed. Then, the lower end of the hinged column 210 is manually pressed to deflect the lower end of the hinged column 210 toward the inside of the lock buckle 209, and the fixing ring 211 fixed on the curtain body 212 is removed. The curtain body 212 can be removed from the lock buckle 209 for cleaning. After the curtain body 212 is removed, the torsion spring 109 provided at the upper end of the hinged column 210 applies elastic force to reset the hinged column 210.

[0038] When the curtain body 212 is in use and needs to be folded, the curtain body 212 is manually moved, and the curtain body 212 drives the lifting rope 207 to swing to one side. The lifting rope 207 is blocked by the block 205 provided on the outer ring of the sliding ring 204 to prevent the lifting rope 207 from falling off from the annular groove 206, so that the force of moving the curtain body 212 is transmitted to the sliding ring 204, and the sliding ring 204 slides in the sliding groove 202 provided on the outer ring of the track 201 through the roller 203 provided on the inner side, thereby realizing the left and right translation and folding of the curtain body 212.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
