[0027] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0028] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-9As shown, a traffic sign structure capable of reducing wind load comprises a sign body 1, a pillar 2 and a mounting rod 3, wherein the sign body 1 is connected to the pillar 2 via the mounting rod 3, and further comprises a first drag reduction mechanism 4 and a second drag reduction mechanism 5, wherein the first drag reduction mechanism 4 is connected to the second drag reduction mechanism 5, the sign body 1 comprises a right plate body 101 and a left plate body 102, the right plate body 101 and the left plate body 102 are movably connected, both ends of the right plate body 101 are provided with limit blocks for limiting the forward flipping of the left plate body 102, a fixing seat 9 is fixedly installed on the back of the right plate body 101, and a mounting sleeve 6 matched with the mounting rod 3 is provided on the fixing seat 9; a limiting groove 601 is provided on the inner wall of the mounting sleeve 6, and an annular baffle 602 for limiting the end of the mounting rod 3 is provided at one end of the mounting sleeve 6 away from the opening, and a connecting mechanism fixed to the mounting sleeve 6 is provided inside the mounting rod 3;

[0031] The second drag reduction mechanism 5 includes a rotating shaft 502 rotatably mounted on one side of the fixing seat 9, and a plurality of torsion springs 501 are fixedly sleeved on the rotating shaft 502. One end of the torsion spring 501 passes through a limiting sleeve mounted on the back of the left plate 102 and abuts against the back of the left plate 102, and the other end of the torsion spring 501 abuts against the fixing seat 9. When encountering strong winds and extreme weather, the left plate 102 deflects when pushed by wind resistance, and the left plate 102 squeezes the torsion spring 501, causing the torsion spring 501 to twist. At the same time, the left plate 102 rotates toward the back of the sign board body 1 with the connection between the left plate 102 and the right plate 101 as the center, which can reduce the area of ​​the sign board body 1 in contact with the strong wind, thereby effectively protecting the sign board body 1.

[0032] The first drag reduction mechanism 4 includes a sliding plate 404 slidably mounted on the right plate body 101, the mark on the sliding plate 404 is integrated with the mark on the surface of the right plate body 101, a vent 405 matching the sliding plate 404 is penetrated on the right plate body 101, a slide groove 406 is provided at the top and bottom of the right plate body 101, and sliding blocks matching the slide groove 406 are provided at both ends of the sliding plate 404; a traction rope 402 is connected to one side of the top and bottom ends of the sliding plate 404, and a traction block 403 is fixedly connected to one end of the traction rope 402, and the two traction blocks 403 are respectively fixedly mounted at both ends of the rotating shaft 502, and a return spring 401 is connected to the other side of the top and bottom ends of the sliding plate 404, and one end of the return spring 401 is fixedly connected to the right plate body 101; when encountering strong winds and extreme weather, the left plate body 102 deflects and squeezes the torsion spring 501 to twist, and the torsion spring 501 twists while driving the rotating shaft 502 to rotate, thereby utilizing the rotating shaft 502 When rotating, the traction rope 402 is pulled by the traction block 403 to move, and the traction rope 402 pulls the sliding plate 404 to move, and the sliding plate 404 slides along the sliding groove 406 through the sliding block, thereby opening the vent 405 on the right plate body 101, so that the wind blowing toward the right plate body 101 can pass through the vent 405, reducing the wind resistance to the right plate body 101, thereby effectively protecting the sign board body 1 and extending its service life;

[0033] During operation, the sign board body 1 is matched and connected through the mounting rod 3 and the mounting sleeve 6. When encountering strong wind extreme weather, the left plate body 102 is deflected when pushed by wind resistance, and the left plate body 102 squeezes the torsion spring 501, so that the torsion spring 501 is twisted. At the same time, the left plate body 102 rotates toward the back of the sign board body 1 with the connection between the left plate body 102 and the right plate body 101 as the center, which can reduce the area of ​​the sign board body 1 in contact with the strong wind, so that the sign board body 1 can be effectively protected;

[0034] The left plate body 102 deflects and squeezes the torsion spring 501 to twist. The torsion spring 501 twists and drives the rotating shaft 502 to rotate. When the rotating shaft 502 rotates, the traction rope 402 is pulled to move through the traction block 403. The traction rope 402 pulls the sliding plate 404 to move. The sliding plate 404 slides along the sliding groove 406 through the sliding block, thereby opening the vent 405 on the right plate body 101, so that the wind blowing toward the right plate body 101 can pass through the vent 405, reducing the wind resistance to the right plate body 101, thereby effectively protecting the sign board body 1 and extending its service life.

[0035] Example 2

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0037] The connecting mechanism includes a transmission screw 301 rotatably mounted inside the mounting rod 3 and a wedge block 306 that can move horizontally inside the mounting rod 3. A screw nut is provided on the transmission screw 301. A movable sleeve 302 for pushing the wedge block 306 to move is fixedly sleeved on the screw nut. The movable sleeve 302 is fixedly connected to the wedge block 306. Limiting blocks 307 for engaging with the mounting sleeve 6 are slidably mounted on both sides of the mounting rod 3. The limiting blocks 307 One end extends to the outside of the mounting rod 3 and is located inside the limiting groove 601, the other end of the limiting block 307 abuts against the wedge block 306, and a first compression spring 308 is provided on the portion of the limiting block 307 located inside the mounting rod 3, one end of the first compression spring 308 is fixedly connected to the inner wall of the mounting rod 3; one end of the transmission screw 301 is fixedly connected to a driven bevel gear 303 for driving the transmission screw 301 to rotate, one side of the driven bevel gear 303 is meshedly connected to a driving bevel gear 304, a rotating rod 305 is rotatably installed on the mounting rod 3, one end of the rotating rod 305 extends to the inside of the mounting rod 3 and is fixedly connected to the driving bevel gear 304 A sealing assembly 8 is provided inside the mounting sleeve 6, and the sealing assembly 8 includes an air storage bag 802 fixedly installed at one end of the mounting sleeve 6 away from the opening, and one end of the air storage bag 802 is fixedly connected to a movable plate 801, and one side surface of the movable plate 801 abuts against one end of the wedge block 306, and the other side surface of the movable plate 801 is fixedly connected to a second compression spring 803, and one end of the second compression spring 803 is fixedly connected to the inside of the mounting sleeve 6. An expansion air bag 804 for sealing the gap between the mounting rod 3 and the mounting sleeve 6 is provided on the inner wall of the mounting sleeve 6, and the expansion air bag 804 is connected to the air storage bag 802 through an air pipe, and the expansion air bag 804 abuts against the surface of the mounting rod 3 when expanded;

[0038] During the working process, when it is necessary to install the sign board body 1 on the mounting rod 3, first, the sign board body 1 is mounted on the mounting rod 3 through the mounting sleeve 6, so that one end of the mounting rod 3 located inside the mounting sleeve 6 abuts against the annular baffle 602 inside the mounting sleeve 6, wherein the mounting rod 3 and the mounting sleeve 6 are each provided with two, and the textures on the transmission screw rods 301 inside the two mounting rods 3 are arranged in opposite directions, and the two ends of the rotating rod 305 respectively extend to the inside of the two mounting rods 3 and are connected to the driving bevel gear 304. At this time, the rotating rod 305 can be driven to rotate, and the driving bevel gear 304 can be driven to rotate. When the driving bevel gear 304 rotates, it meshes with the driven bevel gear 303 to rotate. When the driven bevel gear 303 rotates, it drives the transmission screw rod 301 to rotate, so that the screw nut extends the guide rod provided inside the mounting rod 3 to make a linear motion, and the screw nut moves At the same time, the movable sleeve 302 is driven to move synchronously and push the wedge block 306 to move, wherein at least three wedge blocks 306 are provided and are connected end to end in sequence, and the wedge block 306 squeezes the limit blocks 307 on both sides of the interior of the mounting rod 3 while moving forward, so that the first compression spring 308 on the limit block 307 is squeezed and contracted, and at the same time, one end of the limit block 307 extends to the interior of the limit groove 601, so that the mounting rod 3 is clamped with the mounting sleeve 6, and the wedge block 306 squeezes the movable plate 801 while moving forward, thereby squeezing the air storage bag 802, and at the same time, when the movable plate 801 is squeezed, the second compression spring 803 contracts, and the gas inside the air storage bag 802 enters the expansion air bag 804, so that the expansion air bag 804 expands and squeezes the outer wall of the mounting rod 3, thereby increasing the mounting rod 3 and the mounting sleeve 6. The connection is stable, and the gap between the mounting rod 3 and the mounting sleeve 6 can be sealed to prevent external dust or water from entering the mounting sleeve 6, thereby protecting the connection part and preventing the connection part from being directly exposed to the air and causing rust or dust accumulation, thereby affecting the connection stability. At the same time, the connection method is simple to operate;

[0039] When the sign plate body 1 needs to be disassembled, the rotating rod 305 can be rotated in the opposite direction to make the transmission screw 301 rotate in the opposite direction, and the screw nut drives the movable sleeve 302 to move in the opposite direction, so that the wedge block 306 does not squeeze the limit block 307. At this time, the limit block 307 is separated from the limit groove 601 under the elastic force of the first compression spring 308. At the same time, the wedge block 306 does not apply pressure to the movable plate 801. The elastic force of the second compression spring 803 pushes the movable plate 801 and the air bag 802 to reset. The air bag 802 sucks the gas inside the expansion bag 804 through the air pipe, thereby shrinking the expansion bag 804, which makes it easy to take out the installation rod 3 from the installation sleeve 6. The operation is simple.

[0040] Example 3

[0041] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0042] The connecting mechanism includes a sliding rod 311 slidably installed inside the mounting rod 3, a limiting plate 314 is fixedly installed on the sliding rod 311, a boss is provided inside the mounting rod 3 to block the movement of the limiting plate 314, a tension spring 315 is installed on the limiting plate 314, one end of the tension spring 315 is fixedly connected to the inner wall of the mounting rod 3, traction rods 316 are hinged on both sides of the mounting rod 3, one end of the traction rod 316 is hinged to a limiting block 307, one end of the limiting block 307 extends to the outside of the mounting rod 3 and is located inside the limiting groove 601, an annular protrusion 317 is provided on the part of the limiting block 307 located outside the mounting rod 3 to prevent the limiting block 307 from sliding into the inside of the mounting rod 3, and an annular sealing block 313 for sealing the connection between the mounting rod 3 and the mounting sleeve 6 is provided on the mounting rod 3; A rotating shaft 7 is rotatably installed on the pillar 2, and the rotating shaft 7 passes through the pillar 2. A winding wheel is provided on the end of the rotating shaft 7 close to the sign board body 1. A steel wire rope 312 is fixedly connected to one end of the sliding rod 311, and one end of the steel wire rope 312 is wound around the winding wheel. A limiting ring seat 701 for limiting the rotating shaft 7 is fixedly installed on the side wall of the pillar 2. The rotating shaft 7 passes through the limiting ring seat 701. A rotating sleeve 703 is slidably installed on the end of the rotating shaft 7 away from the sign board body 1. A slider 705 is installed on the inner wall of the rotating sleeve 703. A sliding groove matching the slider 705 is provided on the rotating shaft 7. A limiting gear 704 is fixedly installed on the rotating sleeve 703, and a convex tooth 702 matching the limiting gear 704 is provided on the inner wall of the limiting ring seat 701.

[0043] During the working process, when it is necessary to install the sign board body 1 on the mounting rod 3, first, the sign board body 1 is sleeved on the mounting rod 3 through the mounting sleeve 6, so that the end of the mounting rod 3 located inside the mounting sleeve 6 abuts against the annular baffle 602 inside the mounting sleeve 6. At this time, the annular sealing block 313 can seal the plug-in connection between the mounting sleeve 6 and the mounting rod 3, which can effectively prevent external dust and water from entering the mounting sleeve 6, thereby increasing the stability of the installation. The mounting rod 3 and the mounting sleeve 6 are both provided with two. At this time, the rotating sleeve 703 is driven to rotate, and the rotating shaft 7 is driven to rotate by the rotation of the rotating sleeve 703, so that the winding wheel on the rotating shaft 7 can be driven to wind the wire rope 312. At this time, the wire rope 312 pulls the sliding rod 311 to move, and the sliding rod 311 moves towards the end away from the mounting sleeve 6. At this time, the traction rod 316 is gradually arranged vertically with the sliding rod 311. At this time, the traction rod 316 pushes the limit block 307 to move upward, and one end of the limit block 307 extends to the limit groove 601. The mounting rod 3 is clamped with the mounting sleeve 6, and the limiting plate 314 on the sliding rod 311 moves with the sliding rod 311 and abuts against the boss, and the tension spring 315 is stretched. At this time, the sliding rod 311 cannot move, and the installation is achieved; at this time, the rotating sleeve 703 can be pushed to move on the rotating shaft 7, so that one end of the rotating sleeve 703 is inserted into the limiting ring seat 701, and the limiting gear 704 is meshed with the convex teeth 702 inside the limiting ring seat 701, so that the rotating sleeve 703 can be limited and fixed to prevent the rotating shaft 7 from rotating in the opposite direction;

[0044] When the sign board body 1 needs to be disassembled, at this time, the rotating sleeve 703 is pulled to move on the rotating shaft 7, so that the limiting gear 704 is separated from the limiting ring seat 701, and then the rotating sleeve 703 is driven to rotate in the opposite direction and the rotating shaft 7 is driven to rotate synchronously to unwind the wire rope 312 on the winding wheel. At this time, the sliding rod 311 moves to one end close to the mounting sleeve 6 under the elastic force of the tension spring 315. At this time, the traction rod 316 is pulled by the sliding rod 311 to pull the limiting block 307 downward. The annular protrusion 317 on the limiting block 307 can prevent the limiting block 307 from completely entering the mounting rod 3. At this time, the limiting block 307 is separated from the limiting groove 601, and then the sign board body 1 is pulled to separate the mounting sleeve 6 from the mounting rod 3 for disassembly. The operation is simple and easy to use.
