When the curtain is used as a projection curtain, the problem to be solved is how to spread the curtain smoothly to provide a flat projection surface. In the process of hanging the common curtain cloth 3, the curtain cloth 3 is in a folded state, and particularly, the curtain cloth 3 is vertically folded.

As shown in fig. 1 and 2, in order to solve the above problems, the utility model provides a curtain capable of being used as a projection curtain, which comprises a curtain 3 and a guide rail 1, a pulley 2 is assembled on the guide rail 1, pulley locking components are installed at two ends of the guide rail 1, and the pulley locking components can pull and fix the pulley 2 at two ends of the guide rail 1 along the guide rail 1 to two sides, so as to transversely stretch the curtain 3 above the curtain. The pulley locking assembly is matched with the lower positioning piece 6 through the lifting rope 4, and the lower positioning piece 6 utilizes the gravity thereof to stretch the curtain cloth 3 downwards, so that the curtain cloth is ensured to be flat in the vertical direction.

As shown in fig. 2, 3 and 4, the pulley locking assembly includes a housing 20, a guide wheel 19, a pulling plate 16, a shifting plate 15, a pulling rod 22 and a cross bar 17, wherein the pulling plate 16 and the shifting plate 15 are fixedly connected at 90 degrees, a hinge shaft 26 is arranged at the joint, and two ends of the hinge shaft 26 are assembled on the housing 20; the pulling plate 16 and the pulling plate 15 can rotate around the hinge shaft 26, the hinge shaft 26 is provided with a torsion spring, the pulling plate 15 is attached to the upper inner wall of the shell 20 under the torsion action of the torsion spring, the pulling plate 16 is in a vertical state, the pulleys 2 at the two ends of the curtain cloth 3 are both positioned on the outer side of the pulling plate 15, and the pulleys 2 can freely move on the guide rail 1. The pull plate 16 is matched with a pull rod 22 through a cross rod 17, the pull rod 22 is positioned in a guide seat 25, and a spring 23 is arranged between the pull rod 22 and the guide seat 25; the spring 23 provides a spring force that pushes the pull rod 22 in the middle direction of the guide rail 1.

When the pulleys 2 at the two ends of the curtain cloth 3 need to be locked, the curtain cloth 3 is firstly unfolded until the pulleys 2 at the two ends are close to the pull plate 16, then the lower positioning piece 6 is released, the gravity of the lower positioning piece 6 acts on the lifting rope 4, the lifting rope 4 pulls the pull rod 22 to overcome the elasticity of the spring 23, then the cross rod 17 rotates the shifting plate 15 around the hinge shaft 26 through the pull plate 16 until the pull plate 16 is in a horizontal state, the folded edge 24 of the pull plate 16 hooks the cross rod 17, the shifting plate 15 overcomes the torsion of the torsion spring, the pulley 2 is shifted towards the two ends of the guide rail 1 and the pulley 2 is limited to move towards the middle of the guide rail 1, so that the positioning and locking effects are achieved on the pulley 2, and the upper end of the curtain cloth 3 can be stretched towards the two sides.

As shown in fig. 2, 3 and 5, the lower positioning member 6 is a slender member having a through hole, and the curtain fabric 3 passes through the lower positioning member 6; and motors 8 are installed at two ends of the lower positioning piece 6, the upper ends of the lifting ropes 4 are connected with the tail ends of the pull rods 22 through guide wheels 19, and the lower ends of the lifting ropes are connected with the motors 8. The motors 8 at the two ends of the lower positioning piece 6 provide power for winding the lifting rope 4 so as to control the winding and unwinding of the lower positioning piece 6.

When the projection is not needed, the lower positioning part 6 is folded, is sleeved on the periphery of the guide rail 1 and is fixed with the guide rail 1 through the locking device, the lifting rope 4 is in a loosening state at the moment, and the shifting plate 15 is attached to the upper inner wall of the pulley locking assembly shell 20. When the projection is needed, the lower positioning piece 6 is released along with the motor 8, the lifting rope 4 is pulled close by the gravity of the lower positioning piece 6, and therefore the pull rod 22 is pulled, and the pulley 2 is locked.

In some embodiments, as shown in fig. 2, 3 and 5, the inner walls of the two sides of the lower positioning member 6 are provided with protrusions 9, and the protrusions 9 include grooves 10 arranged at equal intervals. The protruding portion 9 is matched with the pendant 12, the lower positioning piece 6 is hung on the pendant 12, and the curtain cloth 3 is longitudinally stretched under the action of the gravity of the lower positioning piece 6, so that the curtain cloth 3 is guaranteed to be flat.

In some embodiments, the distance between the grooves 10 is equal to the distance between two adjacent pulleys 2 at the upper end of the curtain fabric 3. Due to the arrangement, the lower end of the curtain cloth 3 can be stretched at equal intervals, and wrinkles are avoided.

In some embodiments, as shown in fig. 2 and 6, a hanging pendent 12 is installed on a lower end of the curtain fabric 3, and the hanging pendent 12 includes a drop bar 11 perpendicular to a surface of the curtain fabric 3. The falling rod 11 is matched with the groove 10 of the upper protruding part 9 of the lower positioning piece 6, and two ends of the falling rod 11 are matched in the grooves 10 at two sides of the lower positioning piece 6 to play a limiting role.

In some embodiments, a disc 27 is disposed on the pendant 12, and the diameter of the disc 27 is greater than the distance between the two side protrusions 9. With such an arrangement, the falling rod 11 is prevented from being unable to automatically align with the groove 10 and being separated from the two protrusions 9 when the lower positioning piece 6 is released.

In some embodiments, the lower positioning element 6 is provided with a stop 7, the pulley locking assembly is provided with a lock tongue 21 adapted to the stop 7, the lock tongue 21 and the stop 7 form a locking device, and the lock tongue 21 is driven by an electromagnetic mechanism to be retractable along the direction of the guide rail 1. When the lower positioning piece 6 is folded and the lower positioning piece 6 is lifted to the top end by the motor 8, the bolt 21 extends out and is blocked below the baffle 7, so that the lower positioning piece 6 is locked. When the lower positioning member 6 is released, the latch bolt 21 is retracted.

In some embodiments, the pulley locking assembly has a guide groove 13 formed in a side wall of the housing 20, a hinge shaft 26 installed in the guide groove 13, and a tension spring 14 disposed between the hinge shaft 26 and the housing 20. The tension spring 14 provides a pulling force for pulling the hinge shaft 26 to the middle of the guide rail 1, and after the pulley 2 is locked, the suspension rope 4 further pulls the hinge shaft 26 to move to both sides of the guide rail 1 along the guide groove 13 under the gravity of the lower positioning piece 6, so that more stretching allowance is provided, and the curtain cloth is better unfolded to be in an optimal flat state.

In some embodiments, as shown in fig. 1, elastic pulling ropes 5 connected to the hanging ropes 4 are disposed on both sides of the shade fabric 3, and the elastic pulling ropes 5 are fixed to the hanging ropes 4, so that both sides of the shade fabric 3 are stretched, and a more flat state of the shade fabric 3 is obtained.

The utility model discloses a curtain cloth is with pre-oxygen silk fibre woven fabric as the substrate, and the preferred 0.3-2mm of thickness of this substrate. Meanwhile, a small amount of acrylic resin is prevented from being coated on the base material, so that the effect of fixing hairiness on the surface of the pre-oxidized fiber is achieved. The coating amount of the acrylic resin is controlled to be 20-50g/m²Under the coating amount, the fixing effect of the hairiness on the surface of the pre-oxidized fiber is better.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
