DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-12 The present invention provides a technical solution: a rotating LED display screen, comprising a rotating column as a whole 1, the rotating column as a whole 1 comprising a first fixed column 11, a second fixed column 12 and a rotating column 13, the rotating column 13 is located between the first fixed column 11 and the second fixed column 12, the first fixed column 11 is located below the rotating column 13, a driving motor 14 is arranged inside the first fixed column 11, and a motor output shaft 15 of the driving motor 14 can drive the rotating column 13 to rotate;

[0035] The display screen body 2 is located outside the rotating column 13 and is fixedly connected to the outer wall of the rotating column 13;

[0036] The reversing mechanism 3 is located between the rotating column 13 and the second fixed column 12. The reversing mechanism 3 can drive the rotating column 13 to rotate in the opposite direction through the driving motor 14;

[0037] The switching mechanism 4 is located between the first fixed column 11 and the rotating column 13. The switching mechanism 4 can switch the rotating column 13 to the reversing mechanism 3 to make the rotating column 13 rotate in the reverse direction.

[0038] When the present invention is in use, when there is a foreign object near the display screen body 2, the rotation direction of the rotating column 13 can be switched by the switching mechanism 4, and the rotating column 13 can be reversely rotated by the reversing mechanism 3 to avoid the display screen body 2 from being squeezed and rubbed by the foreign object. At the same time, the switching of the rotation direction of the display screen body 2 can attract passengers to watch.

[0039] The rotating column 13 includes a plurality of teeth 16 fixedly connected to the bottom of the rotating column 13, a driving disk 17 fixedly connected to the outer wall of the motor output shaft 15, a plurality of teeth 2 18 fixedly connected to the upper end of the driving disk 17, the teeth 16 and the teeth 2 18 are both arranged in a ring shape, the teeth 16 and the teeth 2 18 are meshed, a through hole 19 is provided in the center of the rotating column 13, and the motor output shaft 15 passes through the through hole 19;

[0040] The reversing mechanism 3 includes a transmission gear 31 fixedly connected to one end of the motor output shaft 15 away from the driving motor 14, a gear rod 32 fixedly connected to the bottom of the second fixed column 12, a driven gear 33 rotatably connected to the outer periphery of the gear rod 32, the driven gear 33 meshes with the transmission gear 31, a rotating disk 34 is provided at the bottom of the second fixed column 12, a plurality of teeth 35 are fixedly connected to the inner side of the rotating disk 34, the teeth 35 mesh with the driven gear 33, and the rotating disk 34 is located above the rotating column 13;

[0041] When the driving motor 14 is started, the driving disc 17 located on the outer wall of the motor output shaft 15 of the driving motor 14 drives the tooth 1 16 to rotate through the tooth 2 18. At this time, the rotating column 13 can be located above the first fixed column 11 and rotate. The rotating rotating column 13 drives the display screen body 2 to rotate, and dynamic images can be displayed. The dynamic effect can attract people's attention and improve the advertising effect.

[0042] When the motor output shaft 15 rotates, the transmission gear 31 located at the end of the motor output shaft 15 can drive the driven gear 33 to rotate around the gear rod 32. Since the driven gear 33 is engaged with the tooth three 35 fixed on the inner side of the rotating disk 34, the motor output shaft 15 can drive the rotating column 13 to rotate when it rotates, and at the same time, it can drive the rotating disk 34 to rotate in the opposite direction, which paves the way for the rotating column 13 to rotate in the opposite direction.

[0043] A sliding groove 36 is provided on the periphery of the rotating disk 34, and a fixed wall 37 is fixedly connected to the lower end of the second fixed column 12. The fixed wall 37 is located in the sliding groove 36 at one end away from the second fixed column 12 and is slidably connected to the sliding groove 36. When the rotating disk 34 rotates, the fixed wall 37 fixedly connected to the lower end of the second fixed column 12 slides inside the sliding groove 36 provided in the rotating disk 34, which can limit the rotating disk 34 to always rotate in a fixed position, thereby facilitating driving the rotating column 13 to rotate in the opposite direction.

[0044] A plurality of teeth four 38 are fixedly connected to the bottom of the rotating disk 34, and a plurality of teeth five 39 are fixedly connected to the upper end of the rotating column 13. The teeth five 39 are meshed with the teeth four 38, and the teeth five 39 are located below the teeth four 38. When the rotating column 13 moves upward, the teeth one 16 located at the bottom of the rotating column 13 are disengaged from the teeth two 18 at the upper end of the driving disk 17, and at the same time, the teeth five 39 located at the upper end of the rotating column 13 are meshed with the teeth four 38. Since the rotating disk 34 and the driving disk 17 rotate in opposite directions, the rotating disk 34 can drive the rotating column 13 to rotate in the opposite direction at this time, so that the rotating column 13 drives the display screen body 2 to switch the rotation direction.

[0045] The switching mechanism 4 includes a switching groove 41 provided on the outer wall of the display screen body 2. The switching groove 41 is located at both ends of the display screen body 2. The bottoms of the switching grooves 41 at both ends are connected by through grooves 42. A latch 43 is slidably connected inside the through grooves 42. The latch 43 is trapezoidal at one end close to the rotating column 13. An annular protrusion 44 is fixedly connected at the bottom of the rotating column 13. The annular protrusion 44 is trapezoidal at one end close to the latch 43. The inclined surface of the latch 43 fits with the inclined surface of the annular protrusion 44.

[0046] The two ends of the latch pin 43 are provided with oblique holes 46, and the two oblique holes 46 are separated by an oblique rod 47, and the two oblique holes 46 are rotationally symmetrical with the oblique rod 47 as the symmetry axis;

[0047] A switching plate 48 is slidably connected inside the switching slot 41, and one end of the switching plate 48 away from the display screen body 2 is located outside the display screen body 2. A switching rod 49 is fixedly connected to one end of the switching plate 48 close to the through slot 42, and the switching rod 49 is located inside the inclined hole 46.

[0048] When there is a foreign object near the display screen body 2 that blocks the rotation of the display screen body 2, the switching plate 48 located inside the switching groove 41 opened in the display screen body 2 first touches the foreign object and is pushed deep into the switching groove 41, and the switching rod 49 located on the inner side of the switching plate 48 enters the inclined hole 46 opened in the latch 43 through the through groove 42, and because the switching rod 49 abuts against the inclined surface of the inclined rod 47, the switching rod 49 squeezes the inclined rod 47 and pushes the latch 43 to move toward the center of the rotating column 13, and because each switching plate 48 on the same side is fixedly connected by the annular plate 5, each switching plate 48 is simultaneously located in the switching groove 41 and slides through the annular plate 5, and because the inner wall of the through groove 42 is fixedly connected to the limiting rod 45, the limiting rod 45 is located at both ends of the latch 43, and the latch 43 is located on the inner side of the limiting rod 45 and is slidably connected to the limiting rod 45, and each The switch plate 48 on the same side is fixedly connected by the annular plate 5. The sliding of the switch plate 48 at one end can drive all the sliding plates on the same side to slide through the annular plate 5, thereby driving all the latches 43 to move simultaneously through the switch rod 49. Therefore, each latch 43 abuts against the annular protrusion 44 fixedly connected to the bottom of the rotating column 13. Since the inclined surface of the latch 43 fits the inclined surface of the annular protrusion 44, the latch 43 lifts the annular protrusion 44 to move the annular protrusion 44 to the top of the latch 43. At this time, the tooth 16 at the bottom of the rotating column 13 is disengaged from the tooth 2 18 at the upper end of the drive disk 17, and the tooth 5 39 at the upper end of the rotating column 13 is engaged with the tooth 4 38. At this time, the rotating disk 34 drives the rotating column 13 to rotate in the opposite direction to prevent foreign objects from damaging the display screen body 2, and at the same time can attract the attention of passengers and improve the advertising effect.
