And the wedge-shaped surface is facing down, when the stop block 6 slides up with the sliding rod 5, the opening slot 7 is separated from the anti-rotation rod 4, and the display board 2 is in a rotatable state; when the display board 2 is reset from the rotated position, the anti-rotation rod The upper end of 4 squeezes the wedge-shaped surface of the stopper 6, so that the stopper 6 drives the sliding rod 5 to slide upward; when the display panel 2 is reset, the position of the rotation stop rod 4 corresponds to the opening slot 7 again, and the stopper block 6 is not prevented from rotating. The blocking of the rod 4 causes the anti-rotation rod 4 to enter the opening slot 7 to realize the anti-rotation of the display board 2; 8, the anemometer 8 has and is placed between the slide bar 5 and the anemometer 8 and is coaxially connected with the first swivel 9 of the anemometer 8, and the slide bar 5 has the upper end of the slide bar 5 and is placed on the slide bar 5. The coaxially rotating second swivel 10, the first swivel 9 is hinged with a plurality of first connecting rods 11 distributed along the circumference of its own axis, and the second swivel 10 is hinged with a plurality of second links distributed along the circumference of its own axis. Connecting rod 12, the first connecting rod 11 and the second connecting rod 12 are in one-to-one correspondence and are hinged to each other; when the anemometer 8 rotates, the first swivel 9 rotates along with it and passes through the first connecting rod 11 and the second connecting rod 12. The second swivel 10 is driven to rotate at the same time, and the angle between the hinged first link 11 and the second link 12 gradually decreases under the action of the rotational centrifugal force, so that the second swivel 10 moves upward and drives the slide bar 5 Slide up to separate the opening slot 7 from the anti-rotation lever 4 .

Preferably, the stop block 6 is completely placed inside the horizontal beam of the frame 1, and the upper end of the anti-rotation rod 4 is inserted upward into the horizontal beam of the frame 1 and placed in the opening slot 7; the horizontal beam of the frame 1 There is an annular guide groove 13 matched with the anti-rotation rod 4, the lower end of the anti-rotation rod 4 is connected with the display board 2, and the upper end of the anti-rotation rod 4 is slidably placed in the annular guide groove 13, when the display board 2 is on the upper edge of the frame 1. When the hinge axis rotates, the anti-rotation lever 4 rotates along with it and slides along the annular guide groove 13 .

Preferably, there are a plurality of the display panels 2 and are evenly distributed between two upright columns horizontally and side by side. There is a vertical rod 14 at the lower end, and the frame 1 has a connecting plate 15 placed under the display board 2. The vertical rods 14 on the plurality of display boards 2 are simultaneously connected with the connecting board 15 to rotate, so as to realize the synchronous rotation of the plurality of display boards 2; the frame 1 is provided with a space for the vertical rod 14 and the connecting plate 15 to match.

Preferably, the stop block 6 and the frame body 1 are connected by a spring 16 arranged vertically along the axis. Under the elastic force of the spring 16, the stop block 6 moves downward to drive the sliding rod 5 to slide downward.

Preferably, the frame 1 is mounted on the base 17 .

When the present invention is used, the base 17 or the bracket is fixedly installed on the ground, the frame body 1 is installed on the base 17, the display board 2 is used for posting advertisement pages or installing a display screen, and the advertisement pages or display screens on the multiple display boards 2 are displayed respectively. Or stitched together into larger advertising graphics.

In normal use, referring to Figures 1 to 3, the upper end of the anti-rotation rod 4 is placed in the opening slot 7, so the display board 2 cannot be rotated, and the display board 2 will not be deflected when the advertisement is posted or replaced, which is convenient for the posting operation and the later display effect. The stability of the display panel 2 is avoided due to external force, which will affect the viewing.

When encountering strong wind, the anemometer rotates and drives the first swivel 9 to rotate at the same time, and then drives the second swivel 10 to rotate at the same time through the first connecting rod 11 and the second connecting rod 12. The centrifugal force on the first connecting rod 11 and the second connecting rod 12 increases accordingly, so the hinge part of the first connecting rod 11 and the second connecting rod 12 produces centrifugal motion, so that the angle between the two becomes smaller. The vertical position of the first swivel 9 remains unchanged, so the second swivel 10 moves upward and drives the slide bar 5 to slide upward; when the slide bar 5 slides upward, the stopper 6 moves up along with the opening slot 7 Separated from the anti-rotation rod 4, the display board 2 is in a rotatable state. At this time, under the action of the wind, the display board 2 rotates. That is, the resistance of the display board 2 to the airflow is reduced, so that the overall force of the present invention is greatly reduced, and the probability of tipping or being blown down is greatly reduced.

When the wind weakens or stops, the rotational speed of the anemometer decreases, and the centrifugal force on the first connecting rod 11 and the second connecting rod 12 decreases. At the same time, the display board 2 is reset and rotated under the torsion force of the torsion spring 3. During the reset process of the display board 2, the rotation rod 4 is in contact with the front/rear end of the stop block 6, and due to the front/rear of the stop block 6 The end is the wedge-shaped end with the wedge-shaped surface facing downward symmetrically arranged front and rear, so the upper end of the anti-rotation rod 4 squeezes the wedge-shaped surface of the stopper 6 so that the stopper 6 drives the sliding rod 5 to slide upward; when the display panel 2 is reset, the rotation is stopped. The position of the rod 4 and the opening slot 7 corresponds again, and the stop block 6 is not blocked by the anti-rotation rod 4, and then resets downward again and slides down, so that the anti-rotation rod 4 enters the opening slot 7 to realize the anti-rotation of the display board 2; therefore, regardless of the display board 2 or the stopper 6 completes the reset first, and neither will block the reset of each other.

The invention has an ingenious structure. The anemometer is used to stop and operate the display board, which not only has the function of custom measurement, but also enables the display board to be opened in time according to the change of the air flow, so as to reduce the force area of the advertising display board and make the display board affect the airflow. The resistance is significantly reduced, and it has a good windproof effect, which greatly reduces the probability of dumping or blowing, and effectively protects the personal and property safety of nearby people.

The invention can be opened in time according to the size of the wind, without on-site operation, and the components included are all common mechanical structures, which is convenient for maintenance and repair; the posting and replacement of advertising pages are the same as the current common advertising display devices, and there is no professional operation requirement. Easy to use everyday.
