the synchronous device comprises a synchronous wheel and a synchronous belt 20, any end of the rotating shaft penetrates through the supporting frame 11 and is connected to the synchronous wheel, and the synchronous belt 20 is matched with the synchronous wheel and used for driving the synchronous wheel to rotate.
The rotation block 12 interferes with the support frame 11 when rotating, and a general method is to form a certain gap between the rotation block 12 and the rotation groove, but if the gap is too large, the display effect of the signboard is affected. Therefore, two sides of the rotating slot of the present invention have first arc-shaped surfaces, two corresponding sides of the rotating block 12 have second arc-shaped surfaces matching with the first arc-shaped surfaces, the curvature of the first arc-shaped surfaces is the same as the curvature of the second arc-shaped surfaces, and the curvature radius of the second arc-shaped surfaces is the distance from the rotating shaft to the second arc-shaped surfaces, i.e. the cross sections of the first arc-shaped surfaces and the second arc-shaped surfaces are concentric circles with the rotating shaft, so as to ensure that the rotating block 12 will not interfere with the supporting frame 11 when rotating around the rotating shaft under the condition of small gap.
In order to prevent the rotating block 12 from rotating erratically and hardly forming the maximum air leakage gap, a torsion spring is arranged on the rotating shaft, the torsion spring is arranged between the rotating shaft and the rotating block 12 and used for limiting the rotating angle of the rotating block 12, and when the rotating block 12 is in the first state, the rotating block 12 is arranged in parallel with the support frame 11; when the fan is in the second state, the rotating block 12 rotates 90 degrees, the gap formed after the rotating block 12 rotates 90 degrees is the largest, the air leakage rate is the largest, and the wind resistance is the smallest.
In order to enable the rotary blocks 12 to synchronously form the maximum air leakage gap under the condition of wind, the invention further comprises a driving assembly, wherein the driving assembly comprises a first rotating shaft 23, a wind vane 21 arranged at one end of the first rotating shaft 23, a first bevel gear 25 arranged at the other end of the first rotating shaft 23 and a second bevel gear 26 meshed with the first bevel gear 25, and the second bevel gear 26 is coaxially arranged on the synchronous wheel and is used for driving the synchronous wheel to rotate. The support bracket 11 has an upper mounting block 10, and the driving assembly is mounted on the upper mounting block 10.
When the wind level is high, the wind vane 21 rotates too fast, the torsion spring provides reverse force to make the rotating block 12 unable to rotate continuously, the invention also includes a loss prevention assembly, which includes a second rotating shaft 24, a contraction spring 41, a ball 42 and a lifting fan blade 40, one end of the second rotating shaft 24 is connected to the first bevel gear 25, one end of the first rotating shaft 23 is connected to the wind vane 21, the other end has a rotating part, the rotating part is provided with a limit cavity, one end of the contraction spring 41 is connected to the limit cavity, the other end is connected to the ball 42, the ball 42 is partially located in the limit cavity, the other end of the second rotating shaft 24 is provided with a chute for accommodating the rotating part, the rotating part is rotatably arranged in the chute, the chute is provided with a driving cavity for accommodating the ball 42, the ball 42 is partially located in the driving chamber, and the fan blades 40 are disposed on the first rotating shaft 23. When the wind power is large, the wind vane 21 rotates, when the force is large and exceeds the thrust of the contraction spring 41, the force applied to the first rotating shaft 23 is large, so that the contraction spring 41 retracts, at the moment, the ball 42 retracts along with the contraction spring 41, at the moment, the first rotating shaft 23 does not have longitudinal force due to the fact that the limit of the ball 42 is lost, and can move upwards under the effect of the lifting fan blades 40, so that the first rotating shaft 23 is partially separated from the second rotating shaft 24, and the whole assembly is prevented from being damaged due to the fact that the wind speed is too large. As shown in fig. 7, in order to prevent the first rotary shaft 23 from completely separating when rotating, a separation preventing groove is formed in the sliding groove, and a separation preventing block is provided in the rotary part to be received in the separation preventing groove to limit a movable range of the first rotary shaft 23.
When wind exists, the rotating block 12 can generate corresponding deflection along with the wind force, but because the billboard is placed at a high position, if the display surface inclines upwards and turns over, the display content can be broken and can not be effectively displayed, and when the display surface of the rotating block 12 inclines downwards, the content can be clearly seen, and the display effect cannot be greatly influenced, the invention also comprises a reversing component, which comprises a first one-way component, a second one-way component, a third bevel gear 31, a fourth bevel gear 32 meshed with the third bevel gear 31, a first driving gear 33 coaxially arranged with the fourth bevel gear 32 and a second driving gear 34 meshed with the first driving gear 33, wherein the second driving gear 34 is coaxially arranged with the synchronous gear;
