[0015] Preferably, a plurality of rib plates are fixedly connected between the bottom plate and the supporting column.

[0016] According to the above technical solution, the present utility model provides a road traffic sign board, which includes a supporting column and a positioning sleeve installed at the upper end of the supporting column. A chassis is fixedly connected to the outer side of the positioning sleeve. A sign board is detachably installed on the side of the chassis facing away from the positioning sleeve. A rectangular cavity is arranged in the sign board. A rectangular vertical hole communicating with the rectangular cavity is arranged on the outer side of the chassis. A lining plate is slidably inserted into the rectangular cavity in the horizontal direction. Connection blocks are respectively arranged at the upper and lower ends of the end of the lining plate facing the positioning sleeve. A cylindrical rod is arranged between the two connection blocks.

A second through hole is arranged on the lining plate on the side facing away from the positioning sleeve corresponding to each first through hole.

[0017] The working method and beneficial effects of this road traffic sign are as follows: When in normal use, the required indication patterns are sprayed on one or both sides of the sign. These patterns can be sprayed on the inner lining board corresponding to the position of the first through hole according to the spraying position, or can be sprayed avoiding the inner lining board. The opening position of the first through hole can be arranged as needed, for example, in a matrix arrangement. At this time, the sign can normally carry out road traffic indication. When there is a strong wind, by starting the motor to drive the eccentric block to rotate, at this time, the cylindrical rod slides relative to the long circular hole in the long circular hole, and the inner lining board is pulled out of the rectangular cavity through the cylindrical rod. As the pulling distance increases, the overlapping area of the second through hole and the first through hole gradually increases until they completely overlap. At this time, a large part of the external environmental wind can be filtered through the overlapping through holes, thereby weakening the acting force of the environmental wind on the sign, so as to protect the sign and prevent the sign from being blown down by the strong wind. In actual use, the change degree of the indication pattern due to the movement of the inner lining board can be reduced by spraying the indication pattern as much as possible avoiding the position of the first through hole.

[0029] See Figures 1-5 The shown road traffic sign, the road traffic sign includes a support column 4 and a positioning sleeve 6 mounted on the upper end of the support column 4. A chassis 12 is fixedly connected to the outside of the positioning sleeve 6. A sign 11 is detachably mounted on the side of the chassis 12 facing away from the positioning sleeve 6. A rectangular cavity is provided inside the sign 11. A rectangular vertical hole communicating with the rectangular cavity is provided on the outside of the chassis 12. An inner lining plate 22 is slidably inserted horizontally into the rectangular cavity. At the upper and lower ends of the end of the inner lining plate 22 facing the positioning sleeve 6, a connecting block 21 is respectively provided. A cylindrical rod 20 is provided between the two connecting blocks 21. A motor 16 is provided inside the chassis 12. An eccentric block 18 is fixedly sleeved on the shaft body of the motor 16. An elongated circular hole 19 that slidably sleeves on the cylindrical rod 20 is provided at the outer end of the eccentric block 18. A plurality of first through holes 10 penetrating through the rectangular cavity are provided on the sign 11. A second through hole 23 is provided on the inner lining plate 22 corresponding to the side of each first through hole 10 facing away from the positioning sleeve 6.

[0030] Through the implementation of the above technical solution, during normal use, the required indication pattern is sprayed on one or both sides of the sign 11. This pattern can be sprayed on the inner lining plate 22 corresponding to the position of the first through hole 10 according to the spraying position, or it can be sprayed avoiding the inner lining plate 22. The opening position of the first through hole 10 can be arranged as needed, for example, in a matrix arrangement. At this time, the sign 11 can normally carry out road traffic indication. When there is a strong wind, by starting the motor 16, the eccentric block 18 is driven to rotate. At this time, the cylindrical rod 20 slides relative to the long circular hole 19 in the long circular hole 19, and the inner lining plate 22 is pulled out of the rectangular cavity through the cylindrical rod 20. As the pulling distance increases, the overlapping area of the second through hole 23 and the first through hole 10 gradually increases until they completely overlap. At this time, a large part of the external environmental wind can be filtered through the overlapping through holes, thereby weakening the acting force of the environmental wind on the sign 11, so as to protect the sign 11 and prevent the sign 11 from being blown down by the action of a strong wind. During actual use, the change degree of the indication pattern due to the movement of the inner lining plate 22 can be reduced by spraying the indication pattern as much as possible avoiding the position of the first through hole 10. The thickness of the side wall of the sign 11 can also be set to 1.5 - 3 mm to reduce the visual impact caused by the setting of the first through hole 10.

[0031] In this embodiment, an external thread 8 and a retaining ring 5 are successively arranged from top to bottom at the upper end of the support column 4. The positioning sleeve 6 is sleeved on the upper end of the support column 4 and is locked by a nut 7 screwed on the external thread 8. A plurality of positioning ribs 24 are circumferentially arranged on the support column 4 between the external thread 8 and the retaining ring 5. A positioning through groove corresponding to the positioning ribs 24 is arranged inside the positioning sleeve 6.

[0032] The positioning is achieved through a plurality of positioning ribs 24 and positioning through grooves. After positioning the direction of the sign 11 to the required direction, the positioning sleeve 6 is firmly fixed between the nut 7 and the retaining ring 5 through the nut 7.

[0033] In this embodiment, a cover plate 9 is arranged on one side of the chassis 12. The cover plate 9 and the main body of the chassis 12 are connected by a plurality of first bolts 13. Through the setting of the side cover, it is convenient to repair the inside of the chassis 12.
