In the present embodiment, the upper end of the top pillar 24 is in sliding contact with the groove bottom 62, that is, the upper end surface of the top pillar 24 is tightly attached to the groove bottom 62 and can slide relatively, and further, in order to reduce sliding friction, lubricating oil can be applied to the groove bottom 62; of course, in other embodiments, a rolling connection manner may also be adopted, as shown in fig. 5, a ball seat 29 is installed at the upper end of the top column 24, a ball 28 is installed on the ball seat 29, and the ball 28 may extend into the circular groove 61 and roll-connect with the groove bottom 62, so that the design is less in frictional resistance to the groove bottom 62 compared with a sliding connection design manner, and is more conducive to the rotation of the return cylinder 6 around the insertion tube 2 under the pushing action of the top column 24; furthermore, in order to ensure the stable rolling connection of the ball 28 and the groove bottom 62, the groove bottom 62 may be an inverted V-shape, as shown in fig. 4 and 5, so that the ball seat 29 does not swing left and right to hit the groove wall of the circular groove 61 when the ball 28 rolls along the groove bottom 62, which facilitates the smooth rolling of the ball 28.

Generally, as shown in fig. 1 to 4, the warning board 3 includes a sleeve 31 and flat plates 32 fixedly arranged on two sides of the sleeve 31, the sleeve 31 is sleeved on the insertion tube 2, and when strong wind blows the flat plates 32, the flat plates 32 rotate around the sleeve 31; further, in order to facilitate the installation of the warning board 3, a shoulder 20 for stopping the sliding of the sleeve 31 is arranged on the insertion tube 2, as shown in fig. 4; furthermore, in order to enable the top column 24 to push the slot bottom 62 upwards under the pulling of the extension spring 25 to better push the return cylinder 6 to rotate around the insertion tube 2, as shown in fig. 3, the insertion tube 2 is sleeved with a flat bearing 7, the lower end of the flat bearing 7 is in rolling contact with the upper end face of the sleeve 31, and the upper end of the flat bearing 7 tightly pushes the lower end face of the insertion cylinder 4.

In this embodiment, as shown in fig. 4, the lower end of the insertion tube 2 is provided with a mounting groove 23, a fixed pulley block 22 is mounted in the mounting groove 23, and one end of the pull rope 27 bypasses the fixed pulley block 22 and then is connected with the lower end of the top pillar 24; the other end of the pulling rope 27 can penetrate through the inserting pipe 2 and the inserting cylinder 4 to be connected with the warning flag 5, as shown in fig. 2 and 3, the warning flag 5 is provided with a flag cloth 52 and a flag pole 51 connected to one side of the flag cloth 52, two pulling ropes 27 are arranged at the other end of the pulling rope 27 and are respectively connected with the upper end and the lower end of the flag pole 51, as shown in fig. 4, one pulling rope 27 is arranged at the lower end of the pulling rope 27, as shown in fig. 3, the upper end of the pulling rope 27 is divided into two pulling ropes 27, and the two pulling ropes 27 are respectively connected with the upper end and the lower end of the flag pole 51, so that the flag pole 51 cannot be inclined and still remains vertical when the warning flag 5 is blown by strong wind, because some warning signs or building unit information are usually written on the warning flag 5, once the flag pole 51 is inclined, the passing pedestrians and vehicles cannot easily see the information on the flag cloth 52 clearly.

Further, in this embodiment, as shown in fig. 2 and fig. 3, a threading hole 41 is provided on a side surface of the insertion tube 4, the other end of the pulling rope 27 penetrates out of the threading hole 41 to be connected with the flag pole 51, and the hole wall of the threading hole 41 and the inner and outer walls of the insertion tube 4 are in smooth transition through a curved surface 8, so that the design is to reduce the wear of the pulling rope 27 and prolong the service life of the pulling rope 27, preferably, the pulling rope 27 may be a steel wire rope, and lubricating oil may be applied to the curved surface 8 to reduce the friction loss between the pulling rope 27 and the curved surface 8; furthermore, in order to prevent sundries from entering the insert cylinder 4 to influence the movement of the pull rope 27, a cylinder cover 42 can be inserted into the upper end of the insert cylinder 4.

In the embodiment, when the warning flag 5 is blown by strong wind, the warning flag 5 can gradually get away from the inserting cylinder 4, then the top column 24 is pulled by the pull rope 27 to move downwards to leave the circular groove 61, meanwhile, the extension spring 25 is also extended, and then the warning board 3 is blown by strong wind to rotate and drive the return cylinder 6 to synchronously rotate around the inserting tube 2, so that the warning board 3 is effectively prevented from being blown down by strong wind, and the safety of the warning board 3 is greatly improved; when the wind power is reduced, the extension spring 25 pulls the top column 24 to rise, so that the upper end of the top column 24 is inserted into the annular groove 61 again and pushes the return cylinder 6 to rotate to the initial position, the warning board 3 can still return to the initial position after the rotation is finished, and the technical effect of watching pedestrians and vehicles passing by is not influenced; it can be seen that the warning board 3 cannot normally rotate without the upper end of the top column 24 leaving the circular groove 61, but the wind power is required to reach a certain level, that is, the wind power can blow the warning flag 5 to pull the top rod downwards to overcome the pulling force of the tension spring 25, so that the warning board 3 does not rotate when the wind power is small, and certainly, if the wind power blows the warning board 3 to rotate in a specific direction (at this time, the return cylinder 6 rotates to push the upper end of the top column 24 to gradually move from the highest point to the lowest point of the groove bottom 62), the top rod is pushed to descend to overcome the pulling force of the tension spring 25, and the warning board 3 can also rotate, only in this mode, the rotation direction of the warning board 3 is fixed, and the upper end of the top column 24 can be continuously pushed to gradually move from the highest point to the lowest point of the groove bottom 62, once the rotation direction of the warning board 3 changes, or the wind power descends, the upper end of the top column 24 cannot be pushed to move downwards, the warning board 3 is not rotating.

In this embodiment, in order to facilitate the connection of the extension spring 25 and the top pillar 24, as shown in fig. 4, a stopper 26 is fixedly mounted on the top pillar 24, and the lower end of the extension spring 25 is fixedly connected with the stopper 26; furthermore, the presence of the stop 26 prevents the extension spring 25 from being damaged by the downward movement of the top pillar 24 by too great a distance.

In the embodiment, the support 1 is heavy and can be directly placed on the ground to support the insertion tube 2, so that the trouble of inserting the lower end of the insertion tube 2 into the ground for fixing is avoided, the warning device can be conveniently detached and moved at a later stage, and particularly, after the road surface is hardened, the warning device cannot adopt an installation mode that the lower end of the warning device is inserted into the ground, so that the warning device can be applied to various road surfaces.

Further, in this embodiment, as shown in fig. 1, a cavity 11 is formed in the support 1, and sand may be filled into the cavity 11 to increase the weight of the support 1 and prevent the warning device from falling.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
