[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a signal connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] In one aspect of this application, a road traffic guidance device 100 is provided, including a support frame 110 and an indicator plate 120. The indicator plate 120 is disposed on one side of the support frame 110 and can move along the height direction of the support frame 110. The support frame 110 is provided with a receiving cavity, and a transmission part 111 is provided in the receiving cavity. The transmission part 111 is connected to the side edge of the indicator plate 120. Driving the transmission part 111 to rotate can drive the indicator plate 120 to move along the height direction of the support frame 110, so as to set an information guidance cloth on the plate surface of the indicator plate 120.

[0032] Specifically, please refer to Figure 1 and Figure 2 This application provides a road traffic guidance device 100, which includes a support frame 110 and an indicator plate 120. One side of the indicator plate 120 is movably mounted on the support frame 110 and can move up and down along the height direction of the support frame 110.

[0033] The support frame 110 is equipped with a switch door 117, which has a hollow accommodating cavity. A transmission part 111 is installed inside the accommodating cavity. The transmission part 111 is connected to the side edge of the indicator plate 120. The operator can open the switch door 117 to drive the transmission part 111 to rotate, so that the indicator plate 120 rises or falls along the height direction of the support frame 110. After the indicator plate 120 is lowered, an information guidance cloth can be attached to the surface of the indicator plate 120, so that the road traffic guidance device 100 can be set with different information content under different environmental requirements, so as to achieve application in different scenarios. It is suitable for situations where the scene is complex, unplanned or under construction, and road signs need to be continuously updated. It is convenient, fast, economical and practical, and further improves the flexibility and adaptability of the road traffic guidance device 100.

[0034] It should be noted that, firstly, such as Figure 3As shown in this embodiment, a slide groove 113 is provided on the side of the support frame 110 near the indicator plate 120, and the slide groove 113 extends along the height direction of the support frame 110; the side of the indicator plate 120 near the support frame 110 is embedded in the slide groove 113 and can move along the slide groove 113; a side plate 114 is movably provided at the end of the slide groove 113, and the side plate 114 can cover the slide groove 113.

[0035] Specifically, a slide groove 113 is provided on the side of the support frame 110 near the indicator plate 120. The slide groove 113 extends along the height direction of the support frame 110. The side of the indicator plate 120 near the support frame 110 is embedded in the slide groove 113 and can move along the slide groove 113. A side plate 114 is movably provided at the end of the slide groove 113. When the indicator plate 120 is fixed to the top of the support frame 110, the side plate 114 can cover the slide groove 113, which not only makes the support frame 110 look beautiful, but also provides a certain limiting effect for the indicator plate 120, preventing the indicator plate 120 from sliding down the slide groove 113. When the indicator plate 120 needs to be lowered, the side plate 114 can be removed to ensure that the indicator plate 120 can slide down smoothly and reliably from the slide groove 113 to a suitable position.

[0036] Second, in the embodiments of this application, the ends of the support frame 110 are respectively provided with a counterweight 115 and an upper cover plate 116. The counterweight 115 is disposed at the bottom of the receiving cavity of the support frame 110; the upper cover plate 116 is disposed at the top of the receiving cavity of the support frame 110 and covers the receiving cavity.

[0037] Specifically, such as Figure 3 As shown, a counterweight 115 is provided inside the accommodating cavity of the support frame 110. The counterweight 115 is located at the end of the accommodating cavity of the support frame 110. The counterweight 115 has a certain weight, which can further improve the stability of the support frame 110 and the road traffic guidance device 100. The upper cover plate 116 is provided on the top of the accommodating cavity and covers the accommodating cavity so that the support frame 110 can be sealed, which can prevent dust and rainwater from entering, thus providing a certain degree of protection for the internal components of the support frame 110 and improving the reliability and durability of the road traffic guidance device 100.

[0038] The road traffic guidance device 100 provided in this application includes a support frame 110 and an indicator plate 120. The indicator plate 120 is disposed on one side of the support frame 110 and can move along the height direction of the support frame 110. The support frame 110 can provide a certain supporting force for the indicator plate 120. The support frame 110 has a receiving cavity, and a transmission part 111 is provided in the receiving cavity. The transmission part 111 is connected to the side edge of the indicator plate 120. Driving the transmission part 111 to rotate can drive the indicator plate 120 to move along the height direction of the support frame 110, so that the indicator plate 120 rises or falls along the support frame 110 to set information guidance cloth on the plate surface of the indicator plate 120. The road traffic guidance device 100 designed above can realize the rise or fall of the indicator plate 120 by rotating the transmission part 111, and different information guidance cloths can be affixed to the indicator plate 120. It does not require internal circuit equipment, is simple to assemble, and has strong adaptability to the use environment.

[0039] In one feasible embodiment of this application, the transmission unit 111 includes a drive gear 1111 rotatably disposed at the bottom of the accommodating cavity of the support frame 110, a driven gear 1112 drively disposed at the top of the accommodating cavity, and a chain 1113 sequentially wound around the drive gear 1111 and the driven gear 1112; one end of the chain 1113 is movably connected to the side edge of the indicator plate 120 through the driven gear 1112. Rotating the drive gear 1111 can drive the chain 1113 to move around the drive gear 1111 and the driven gear 1112, thereby driving the indicator plate 120 to move along the height direction of the support frame 110.

[0040] Specifically, such as Figure 3 As shown, the transmission unit 111 includes a driving gear 1111, a driven gear 1112, and a chain 1113. The driving gear 1111 is rotatably disposed at the bottom of the receiving cavity of the support frame 110, and the driven gear 1112 is rotatably disposed at the top of the receiving cavity of the support frame 110. One end of the chain 1113 is wound around the driving gear 1111 and the driven gear 1112 in sequence, and is movably connected to the side edge of the indicator plate 120 through the driven gear 1112. The operator can open the switch door 117 to drive the driving gear 1111 to rotate, so that the driven gear 1112 is rotated through the chain 1113, thereby causing the indicator plate 120 to rise or fall.

[0041] It should be noted that a handle may be provided on the drive gear 1111 so that the operator can rotate the drive gear 1111 in a clockwise or counterclockwise direction.

[0042] In one feasible embodiment of this application, the indicator plate 120 includes a body 121 and a frame 122 disposed around the periphery of the body 121; a support ring 1221 is fixedly disposed on the side of the frame 122 near the driven gear 1112, and a force-bearing block 1222 is disposed inside the support ring 1221; a support chain 1223 is disposed on the side of the force-bearing block 1222 facing the support frame 110; the end of the chain 1113 is movably connected to the support chain 1223.

[0043] Specifically, such as Figure 2 As shown, the indicator panel 120 includes a body 121, on which guidance information can be directly printed or covered with a guidance cloth. A frame 122 is arranged around the body 121, which can fix and limit the body 121 to improve the reliability and stability of the road traffic guidance device 100. A support ring 1221 is arranged on the side of the frame 122 near the driven gear 1112. The support ring 1221 is arc-shaped and has a force-bearing block 1222 inside. The support ring 1221 can limit the force-bearing block 1222 to a certain extent, so that the force-bearing block 1222 can move within the range of the support ring 1221 without falling off. A support chain 1223 is provided on the side of the force-bearing block 1222 facing the support frame 110. The end of the support chain 1223 is movably connected to the chain 1113, so that the chain 1113 of the transmission part 111 can be fixedly connected to the frame 122 of the indicator plate 120, thereby making the connection between the chain 1113 and the indicator plate 120 more stable and reliable.

[0044] Furthermore, an auxiliary gear 1114 is rotatably disposed within the accommodating cavity of the support frame 110. The auxiliary gear 1114 is disposed on the periphery of the driven gear 1112 facing the driving gear 1111. The chain 1113 is sequentially wound around the driving gear 1111, the auxiliary gear 1114, and the driven gear 1112. A guide plate 112 is fixedly disposed within the accommodating cavity. The guide plate 112 is disposed on the side of the driving gear 1111 facing the driven gear 1112. One end of the chain 1113 is sequentially wound around the driving gear 1111, the auxiliary gear 1114, and the driven gear 1112, and is movably connected to the end of the support chain 1223. The other end of the chain 1113 is connected to the guide plate 112.

[0045] Specifically, such as Figure 3As shown, an auxiliary gear 1114 is also provided in the accommodating cavity of the support frame 110. The auxiliary gear 1114 is located on the periphery of the driven gear 1112 facing the driving gear 1111. The chain 1113 is sequentially wound around the driving gear 1111, the auxiliary gear 1114 and the driven gear 1112. The setting of the auxiliary gear 1114 enables the chain 1113 to be better connected and driven by the driving gear 1111 and the driven gear 1112, preventing the chain 1113 from being suspended after being set on the driving gear 1111 and the driven gear 1112 respectively, thus improving the reliability of the road traffic guidance device 100.

[0046] A guide plate 112 is also provided inside the accommodating cavity. The guide plate 112 is located on the side of the driving gear 1111 facing the driven gear 1112. One end of the chain 1113 is sequentially wound around the driving gear 1111, the auxiliary gear 1114 and the driven gear 1112, and is movably connected to the end of the support chain 1223. The chain 1113 can move along the setting direction of the guide plate 112 by the rotation of the driving gear 1111. The guide plate 112 can play a good guiding role in the movement direction of the chain 1113, ensuring the reliability of the drive unit.

[0047] In one possible embodiment of this application, the frame 122 includes a main frame 123 and a first connecting beam 124 and a second connecting beam 125 disposed within the frame of the main frame 123. The first connecting beam 124 and the second connecting beam 125 are disposed opposite to each other on both sides of the body 121. A fixing groove 126 is slidably disposed between the first connecting beam 124 and the second connecting beam 125. The fixing groove 126 is perpendicularly connected to the first connecting beam 124 and the second connecting beam 125 respectively. The opening of the fixing groove 126 faces the side away from the support frame 110. The body 121 is engaged in the opening of the fixing groove 126 by the side edge of the main frame 123 to be fixedly connected to the main frame 123.

[0048] Specifically, such as Figure 4 As shown, the frame 122 includes a main frame 123, which is disposed on opposite sides of the body 121. The frame 122 also includes a first connecting beam 124 and a second connecting beam 125 disposed within the frame of the main frame 123, which are disposed opposite to each other on opposite sides of the body 121.

[0049] A fixing groove 126 is slidably provided between the first connecting beam 124 and the second connecting beam 125. The fixing groove 126 is perpendicularly connected to the first connecting beam 124 and the second connecting beam 125 respectively. The opening of the fixing groove 126 faces the side away from the support frame 110. The main body can extend into the main frame 123 from the side edge of the main frame 123 and engage with the opening of the fixing groove 126, so that the main body can be more stably connected to the frame 122 through the fixing groove 126.

[0050] In one possible embodiment of this application, the main frame 123 further includes a displacement groove 127, which is disposed between the first connecting beam 124 and the second connecting beam 125 and is perpendicularly connected to the first connecting beam 124 and the second connecting beam 125 respectively; the opening of the displacement groove 127 faces away from the support frame 110, and the fixing groove 126 can be locked in the displacement groove 127; a push-pull rod 1271 is provided on the displacement groove 127, and driving the push-pull rod 1271 to move can cause the displacement groove 127 to drive the fixing groove 126 to move along the extension direction of the first connecting beam 124 and the second connecting beam 125.

[0051] Specifically, such as Figure 7 As shown, the main frame 123 also includes a displacement groove 127, which is slidably disposed between the first connecting beam 124 and the second connecting beam 125 and is perpendicularly connected to the first connecting beam 124 and the second connecting beam 125 respectively; the opening of the displacement groove 127 is disposed facing away from the support frame 110, and the fixing groove 126 can be locked in the opening of the displacement groove 127; a push-pull rod 1271 is provided on the displacement groove 127. When the main body is locked in the fixing groove 126 and the fixing groove 126 is locked in the displacement groove 127, the main body 121 can be moved left and right along the first connecting beam 124 and the second connecting beam 125 by moving the push-pull rod 1271 left and right, so as to move the position of the main body 121 and facilitate the installation and disassembly of the main body 121.

[0052] Furthermore, a limiting shell 1231 is provided on the side of the main frame 123 near the support frame 110. A pressure spring 1232 is provided on the side of the limiting shell 1231 facing the displacement groove 127. A protrusion 1233 is provided on the side of the pressure spring 1232 facing the displacement groove 127. The side of the displacement groove 127 facing the protrusion 1233 can engage with the protrusion 1233.

[0053] Specifically, such as Figure 4As shown, a limiting shell 1231 is provided on the side of the main frame 123 near the support frame 110. The limiting shell 1231 is vertically arranged between the first connecting beam 124 and the second connecting beam 125. A pressure spring 1232 is provided on the side of the limiting shell 1231 facing the displacement groove 127. A protrusion 1233 is provided on the side of the pressure spring 1232 facing the displacement groove 127. When the push-pull rod 1271 drives the fixing groove 126 and the displacement groove 127 to move towards the limiting shell 1231, the protrusion 1233 can engage with the displacement groove 127 to fix the position of the displacement groove 127 and the fixing groove 126, thereby ensuring the position of the main body is fixed. The pressure spring 1232 provides a buffering effect during the contact and locking process between the protrusion 1233 and the displacement groove 127, making the locking process between the protrusion 1233 and the displacement groove 127 more stable and reliable, while also providing some protection for the body 121, the displacement groove 127 and the fixing groove 126.

[0055] Specifically, such as Figure 5 and Figure 6 As shown, a fixed flat strip 128 and a displacement flat strip 129 are respectively provided on the side of the main frame 123 away from the support frame 110; the fixed flat strip 128 and the displacement flat strip 129 are spaced apart and are perpendicular to the first connecting beam 124 and the second connecting beam 125 respectively.

[0056] Limiting blocks 130 are respectively provided at both ends of the fixed flat strip 128 and the displacement flat strip 129. The limiting blocks 130 are set perpendicular to the first connecting beam 124 and the second connecting beam 125. The ends of the fixed flat strip 128 and the displacement flat strip 129 can pass through the limiting blocks 130 and extend outward. The limiting blocks 130 can play a certain limiting and fixing role for the fixed flat strip 128 and the displacement flat strip 129. One side of the body 121 is inserted through the gap between the fixed flat strip 128 and the displacement flat strip 129, and the body 121 is moved toward the support frame 110. During the movement, the body 121 is flattened by the pressure of the fixed flat strip 128 and the displacement flat strip 129 on both sides, which improves the appearance of the road traffic guidance device 100.

[0057] Furthermore, the displacement paving strip 129 and the fixed paving strip 128, which pass through the limiting block 130, are respectively provided with a first limiting post 1291 and a second limiting post 1281. The first limiting post 1291 and the second limiting post 1281 are respectively disposed between the limiting block 130 and the main frame 123. The main frame 123 has a relief groove 1234. The end of the first limiting post 1291 facing away from the displacement paving strip 129 passes through the relief groove 1234 and can move within the relief groove 1234. The end of the second limiting post 1281 facing away from the fixed paving strip 128 passes through the relief groove. Within 1234, and is able to move within the clearance groove 1234; a limiting crossbar 131 is provided between the first limiting post 1291 and the second limiting post 1281, and a tension spring 1311 is sleeved on the limiting crossbar 131; driving the first limiting post 1291 to move toward the side away from the second limiting post 1281 can drive the displacement flat strip 129 to move toward the side away from the fixed flat strip 128, so as to remove the body 121; releasing the first limiting post 1291, the tension spring 1311 releases energy to drive the displacement flat strip 129 to move toward the side of the fixed flat strip 128 and reset.

[0058] Specifically, such as Figure 5 and Figure 6 As shown, the ends of the fixed flat strip 128 and the displacement flat strip 129 can pass through the limiting block 130 and extend outward. After the end of the displacement flat strip 129 passes through the limiting block 130, a first limiting post 1291 is fixedly installed at its end. After the end of the fixed flat strip 128 passes through the limiting block 130, a second limiting post 1281 is fixedly installed at its end. The first limiting post 1291 and the second limiting post 1281 are disposed between the first connecting beam 124, the second connecting beam 125 and the main frame 123. Correspondingly, an avoidance groove 1234 is provided on the main frame 123. The first limiting post 1291 and the second limiting post 1281 can pass through the avoidance groove 1234 of the main frame 123 and can move within the range of the avoidance groove 1234.

[0059] A limiting crossbar 131 is provided between the first limiting post 1291 and the second limiting post 1281. One end of the limiting crossbar 131 is connected to the first limiting post 1291 and the other end is connected to the second limiting post 1281. A tension spring 1311 is sleeved on the limiting crossbar 131. When the main body 121 needs to be disassembled, the first limiting post 1291 is moved toward the side away from the second limiting post 1281. At this time, the first limiting post 1291 can drive the displacement flat strip 129 to move toward the side away from the fixed flat strip 128, so that the gap between the fixed flat strip 128 and the displacement flat strip 129 increases. At this time, the tension spring 1311 stores energy. The increased gap between the fixed flat strip 128 and the displacement flat strip 129 makes it easier to pull out the main body 121. After the main body 121 is pulled out, the first limiting post 1291 is released. At this time, the tension spring 1311 releases energy, so as to drive the displacement flat strip 129 back to its original position.

[0060] It should be noted that a fixing plate 132 can also be provided between the first limiting post 1291 and the second limiting post 1281. The fixing plate 132 has a mounting hole in its center, allowing the limiting crossbar 131 and the tension spring 1311 to pass through the fixing plate 132 and be fixedly connected to the first limiting post 1291 and the second limiting post 1281, respectively. The fixing plate 132 further improves the stability of the frame 122.

[0061] By setting the first limiting post 1291, the second limiting post 1281 and the tension spring 1311, the stability of the fixed flat strip 128 and the displacement flat strip 129 is improved, while ensuring that their movement process is more reliable.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
