wherein, the transmission shaft 6 and the half shaft two 21 are provided with a rotating shaft supporting plate 49, and the rotating shaft supporting plate 49 is fixed on the inner top wall of the advertisement installation box body 3.

In the embodiment, when a pedestrian passes through the advertisement door, firstly, the door body 2 is pulled open through the handle or the door body 2 is directly pushed, the door body 2 can drive the advertisement installation box body 3 to be opened, and the door body 2 and the advertisement installation box body 3 can rotate through the hinge 48; in the rotating process of the advertisement installation box body 3, under the action of the first pull rope 9, the rope pulley 7 can rotate, the rope pulley 7 can drive the transmission shaft 6 to rotate, the transmission shaft 6 can tighten the first coil spring 8 when rotating, meanwhile, the transmission shaft 6 can also drive the pinion 13 to rotate, the pinion 13 can drive the bull gear 14 to rotate, at the moment, the bull gear 14 can drive the energy storage sleeve 15 to rotate through the first pawl 16, the energy storage sleeve 15 cannot drive the inner sleeve 19 to rotate through the second pawl 18, at the moment, the energy storage sleeve 15 can drive the second coil spring 17 to tighten energy storage, at the moment, because the elasticity of the second coil spring 17 is small, the resistance of the steel ball 36 cannot be overcome, and the energy storage sleeve 15 cannot drive. When people do not push or pull the door body 2 any more, the transmission shaft 6 can rotate reversely under the action of the elastic force of the coil spring I8, and the transmission shaft 6 can drive the rope pulley 7 to rotate to tighten the pull rope I9; meanwhile, the transmission shaft 6 can drive the small gear 13 to rotate, the small gear 13 can drive the large gear 14 to rotate, and the large gear 14 cannot drive the energy storage sleeve 15 to rotate through the first pawl 16; after the door body 2 is closed, the next time of opening the door can be waited for, and the second coil spring 17 is continuously tightened to store energy.

After multiple times of energy storage, when the elastic force of the second coil spring 17 can overcome the resistance of the steel balls 36, under the elastic force action of the second coil spring 17, the inner sleeve 19 can drive the second half shaft 21 to rotate, the second half shaft 21 can drive the first half shaft 20 to rotate through the electromagnetic clutch 22, the first half shaft 20 can drive the gear shaft 24 to rotate through the first gear 23, the gear shaft 24 can drive the third gear 26 to rotate through the second gear 25, the third gear 26 can drive the upper stick 28 to rotate through the upper stick connecting shaft 27, the upper stick 28 can drive the lower stick 30 to rotate through the advertising cloth 29 when rotating, the advertising cloth 29 on the lower stick 30 is wound on the upper stick 28, and the lower stick 30 can tighten the third coil spring 33 when rotating; meanwhile, the first half shaft 20 drives the weight 44 to move upwards through the second pull rope 42 when rotating; when the first half shaft 20 drives the rotary disc 34 to rotate for one circle, the elastic force of the second coil spring 17 is released partially, and the rotary disc 34 stops rotating under the resistance of the steel balls 36; the rotating disc 34 rotates for a circle, and the advertising cloth 29 just moves for one advertising picture; at this time, the next door opening can be waited for, and the second coil spring 17 can be continuously tightened to store energy, and when the elastic force of the second coil spring 17 can overcome the resistance of the steel ball 36, the picture of the advertising cloth 29 can be continuously replaced.

After replacing advertisement pictures for many times, the heavy hammer 44 will move upwards to the position touching the first travel switch 46, and when the heavy hammer 44 touches the first travel switch 46, the first travel switch 46 will control the electromagnetic clutch 22 to release through the PLC controller, so that the first half shaft 20 cannot drive the second half shaft 21 to rotate; at this time, under the action of the gravity of the weight 44 and the elastic force of the coil spring three 33, the half shaft one 20 rotates in the reverse direction, the half shaft one 20 drives the turntable 34 to rotate in the reverse direction, when the turntable 34 rotates in the reverse direction, the resistance of the steel ball 36 to the turntable 34 is small, when the weight 44 descends to the bottom end, the weight 44 touches the stroke switch two 47, the stroke switch two 47 controls the electromagnetic clutch 22 to hold tightly through the PLC controller, so that the half shaft one 20 can drive the half shaft two 21 to rotate, at this time, the advertising cloth 29 on the upper stick 28 is wound on the lower stick 30 again, the original state of the device is recovered, and the next cycle is waited.

The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
