[0026] See also Figure 1-Figure 3 A movable curtain comprises a base 1, on which two supporting columns 2 are vertically arranged, and one of the supporting columns 2 is provided with a handle 12. A first mounting plate 31 and a second mounting plate 32 are respectively provided on the tops of the two supporting columns 2, and a first mounting seat 4 is respectively provided on the first mounting plate 31 and the second mounting plate 32, and a rotating shaft 5 is rotatably provided on the two first mounting seats 4, and the rotating shaft 5 is horizontally arranged, and a curtain roller 19 is provided on the rotating shaft 5, and a curtain 6 is provided on the curtain roller 19, and one end of the curtain 6 is fixed on the curtain roller 19, and the curtain 6 is wound around the outer periphery of the curtain roller 19, and one end of the rotating shaft 5 passes through the first mounting seat 4 on the first mounting plate 31, and a winding assembly is provided at the passing end of the rotating shaft 5; and a moving wheel 13 is rotatably provided at the bottom of the base 1. The winding assembly drives the rotating shaft 5 to rotate, and then drives the curtain roller 19 to rotate, and then drives the curtain 6 to rotate, so that the curtain 6 is rolled up, so that the surface of the unused curtain 6 is kept clean and tidy, which is convenient for the next use. The arrangement of the moving wheels 13 makes the movable curtain movable and convenient to use.

[0027] The first mounting plate 31 is provided with a second mounting seat 7, and the protruding end of the rotating shaft 5 is rotatably arranged on the second mounting seat 7. The arrangement of the second mounting seat 7 makes the rotating shaft 5 rotate more smoothly.

[0028] like Figure 2 , Figure 3 The winding assembly includes a mounting frame 8, a worm wheel 9 and a worm 10. The mounting frame 8 is vertically arranged on the first mounting plate 31. The cross-section of the mounting frame 8 is gate-shaped. The worm 10 is rotatably arranged on the mounting frame 8. The worm 10 is arranged horizontally. The worm wheel 9 is sleeved on the protruding end of the rotating shaft 5. The worm 10 is located on the top of the worm wheel 9, and the worm 10 is meshed with the worm wheel 9. One end of the worm 10 passes through the mounting frame 8, and the protruding end of the worm 10 is connected to a motor 16. After the mobile curtain is used, the motor 16 is operated to drive the worm 10 to rotate, and then drives the worm wheel 9 along Figure 2 The direction of the arrow in the middle rotates, driving the rotating shaft 5 and the curtain roller 19 along the Figure 2 The direction of the arrow in the middle rotates, and then drives the curtain 6 on the curtain roller 19 along Figure 2 The curtain 6 is rotated in the direction of the middle arrow, so that the curtain 6 is wound around the curtain roller 19, thereby rolling up the curtain 6.

[0029] The first protective cover 17 is provided on the top of the first mounting plate 31 and the second mounting plate 32. The first protective cover 17 is surrounded by a top plate and four side plates, and has no bottom plate, so as to facilitate the rolling of the curtain 6. The first protective cover 17 covers the first mounting seat 4, the second mounting seat 7, the rotating shaft 5, the curtain roller 19, the curtain 6 on the curtain roller 19, and the rolling assembly, so as to prevent the curtain 6 from being stained with dust after rolling up, which affects the use. The first protective cover 17 in the utility model is detachable, so as to facilitate the maintenance of the mobile curtain and the replacement of parts.

[0030] The bottom of the base 1 is provided with a connecting plate 14, and the moving wheel 13 is rotatably arranged at the bottom of the connecting plate 14. The connecting plate 14 is screwed with a screw rod 15, which is arranged vertically. The bottom of the screw rod 15 is provided with a bottom plate, and the top of the screw rod 15 is provided with a rotating plate. The rotating plate is rotated to drive the screw rod 15 to rise and fall, and drive the bottom plate to rise and fall, so as to adjust the height of the bottom plate.
