[0031] Example 1

[0032] One of the implementation methods of the central axis rotating mobile splicing screen device of the utility model is as follows: Figures 1 to 7 As shown, it includes: a guide rail structure 4, and a plurality of movable mechanisms 3 arranged on the guide rail structure 4; the guide rail structure 4 is hoisted on the building structure, and the movable mechanisms 3 are movably connected to the guide rail structure 4; a rotating mechanism is also provided on the movable mechanism 3, and the rotating mechanism is connected to a mounting frame 31 through a rotating shaft 11, and a display screen 2 is fixed on the mounting frame 31.

[0033] The guide rail structure 4 includes: a mounting main beam 41 , the mounting main beam 41 further includes a first mounting portion 42 and a second mounting portion 43 , and a first guide rail 421 and a second guide rail 431 are fixedly disposed at the bottom of the first mounting portion 42 and the second mounting portion 43 , respectively.

[0034] The guide rail structure 4 is further provided with a rack 44 , and the rack 44 is arranged in the first guide rail 421 and / or the second guide rail 431 .

[0035] The movable mechanism 3 includes: a mounting plate 31; the mounting plate 31 is a U-shaped structure, one wing or both wings of which are fixed with a mobile driver 33, and the mobile driver 33 is connected to a gear 331 for driving the gear 331 to rotate. The gear 331 is connected to a corresponding rack 44. The mobile driver 33 drives the gear 331 to rotate forward or reverse, thereby driving the display screen 2 to reciprocate along the direction of the rack 44.

[0036] In this embodiment, the moving drive 33 includes a first servo motor and a planetary reducer, and the gear 331 is arranged on the planetary reducer. The moving distance can be precisely controlled by driving the first servo motor.

[0037] Specifically, a plurality of running wheels 34 are respectively disposed on the two wings of the mounting plate 31 ; each running wheel 34 is respectively disposed in the corresponding first guide rail 421 or the second guide rail 431 to play a guiding role.

[0038] The rotating mechanism includes a turntable 311 and a rotating drive 32; the turntable 311 is connected to the rotating shaft 11, and the rotating drive 32 is connected to the turntable 311 axis. The turntable 311 is arranged on the mounting plate 31, and the rotating drive 32 is arranged on the turntable 311. Under the drive of the rotating drive 32, the turntable 311 rotates to drive the rotating shaft 11, the mounting frame 1 and the display screen 2 to rotate.

[0039] In this embodiment, the rotation drive 32 includes a second servo motor and a worm gear reducer, and the rotation angle can be precisely controlled by the second servo motor.

[0040] Furthermore, the two wings of the mounting plate 31 are respectively provided with a plurality of anti-jumping guide wheels 35; the anti-jumping guide wheels 35 are arranged below the corresponding running wheels 34. The first guide rail 421 and the second guide rail 431 are both C-shaped structures, the upper side of the C-shaped structure is fixedly connected to the first mounting portion 42 or the second mounting portion 43, one side of the lower side abuts against the corresponding running wheel 34, and the other side of the lower side abuts against the corresponding anti-jumping guide wheel 35. When the movable mechanism 3 moves, the screen body can be prevented from tilting when encountering thrust on the front of the display screen 2, thereby ensuring the flatness of each display screen 2 when being spliced.

[0041] Furthermore, a guide rib 341 is provided on one side of the running wheel 34, and the guide rib 341 is provided between the first guide rail 421 or the second guide rail 431 and the corresponding wing of the mounting plate 31. When the movable mechanism 3 moves, it further plays a guiding role and can offset the rotation force when the display screen 2 rotates, so as to prevent the display screen 2 from being unevenly spliced ​​after rotation.

[0042] When it is necessary to Figure 7 The storage status of Figure 6 When the display state is displayed, the turntable 311 on the movable mechanism 3 rotates under the drive of the rotation drive 32, thereby driving the rotation shaft 11, the mounting frame 1 and the display screen 2 to rotate; when multiple display screens 2 are rotated and spliced, they can first be moved in sequence by driving the mobile drive 33 forward and backward, so that each display screen 2 moves, rotates, and then moves again, and finally the multiple display screens 2 can be seamlessly spliced ​​together with a positioning accuracy of 0.2mm, and no splicing gap can be seen during the use of the display screen 2.
