Description

Technical Field

[0001] The invention relates to the field of traffic signs, in particular to a modular LED road traffic sign. Background Art

[0002] Road traffic signs are graphic symbols that display traffic regulations and road information. They can express traffic regulations in a vivid, specific and concise manner, and also express content that is difficult to describe in words. They are used to manage traffic and indicate driving directions to ensure smooth roads and safe driving. In road traffic, traffic signs are used to display and explain road conditions. Traditional traffic signs use LED screens to adjust and control changing road environments.

[0003] Existing LED road traffic signs are usually installed above the road and fixed with support frames, bolts and other structures. However, various situations may occur on existing roads, such as continuous turns, long straight lines, falling rocks, wild animals and other single or multiple situations occurring at the same time. Therefore, LED road traffic signs at different locations need to use multiple groups of different LED display screens. Therefore, when assembling the traffic signs, it is necessary to install appropriate LED display screens according to the usage.

[0004] However, existing display screens are usually modular in structure. During the installation process, bolts and support rods are used to fix and limit the LED display screens. However, there is a lot of information that needs to be broadcast on existing roads, usually including road surface, direction, speed limit, whether to pass, etc. Therefore, multiple sets of LED display screens are used for broadcasting during use. However, when fixing existing traffic signs, they are usually fixed with bolt cross bar structures. The top and bottom ends of the traffic signs are located on the outside of the cross bar. In extreme weather, the wind resistance is large, which can easily cause the traffic sign to deform or be damaged. Secondly, if the LED screen encounters high temperature weather during use, the service life of the LED display screen will be reduced due to poor heat dissipation. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a modular LED road traffic sign to solve the technical problems that traffic signs are easily damaged in extreme weather and the heat dissipation of traffic signs is poor.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a modular LED road traffic sign, comprising a support frame, the top of the support frame is connected to a cross frame, the top and bottom of the cross frame are symmetrically installed with guzheng practice fixing plates, and each group of fixing plates is installed with an adjusting cylinder on the outside of the cross frame, a controller is installed in the middle of the fixing plate, a cross bar is connected to the side of the cross frame, two groups of main display screens are installed on the outer wall of the cross bar, and the positions of the main display screens and the fixing plates are aligned, the top and bottom of the main display screen are installed with a sub-display screen, the sub-display screen is rotatably connected to the main display screen, a main fixing plate is installed on the back of the main display screen, a sub-fixing plate is installed on the back of the sub-display screen, and the sub-fixing plate is movably connected to the output end of the adjusting cylinder, a plurality of heat dissipation slots are provided inside the sub-display screen, wind speed detectors are installed on both sides of the fixing plate located inside the cross frame, and fan blades are installed at the output end of the wind speed detector.

[0007] By adopting the above technical solution, it is convenient to adjust the angle of the secondary display screen. In windy weather, the secondary display screen can be rotated to a position parallel to the wind to reduce the wind resistance of the secondary display screen.

[0024] 2. The present invention also increases the contact area between the air and each group of fixed plates through the heat dissipation grooves during the use of the display screen, thereby improving the heat dissipation effect of the display screen. In extreme weather, when the auxiliary display screen is rotated to a horizontal position, the air flow can pass through the auxiliary fixed plate through the heat dissipation grooves, thereby reducing the contact area between the air flow and the auxiliary fixed plate, improving the stability of the auxiliary fixed plate, and thus improving the stability of the display screen.

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] The following describes an embodiment of the present invention based on its overall structure.

[0038] A modular LED road traffic sign, such as Figures 1 to 6 As shown, it includes a support frame 1, the top of the support frame 1 is connected to a cross frame 101, the bottom of the support frame 1 is connected to a mounting seat 102, the support frame 1 is fixedly connected to the ground through the mounting seat 102, a plurality of reinforcing rods 103 are installed inside the cross frame 101, the reinforcing rods 103 reinforce the cross frame 101, the top and bottom of the cross frame 101 are symmetrically installed with guzheng practice fixing plates 2, and each group of fixing plates 2 is installed with an adjustment cylinder 4 on the outside of the cross frame 101, a controller 3 is installed in the middle of the fixing plate 2, a cross bar 104 is connected to the side of the cross frame 101, two groups of main display screens 5 are installed on the outer wall of the cross bar 104, and the main display screen 5 is aligned with the position of the fixing plate 2, the top and bottom of the main display screen 5 are installed with auxiliary display screens 6, and the auxiliary display screen The screen 6 is rotatably connected to the main display screen 5. A main fixed plate 501 is installed on the back of the main display screen 5. A secondary fixed plate 601 is installed on the back of the secondary display screen 6. The secondary fixed plate 601 is movably connected to the output end of the adjusting cylinder 4. A plurality of heat dissipation slots 605 are provided inside the secondary display screen 6. Wind speed detectors 201 are installed on both sides of the fixed plate 2 located inside the cross frame 101. Fan blades 202 are installed at the output end of the wind speed detector 201. A fixed frame is installed on the inner wall of the fixed plate 2. The wind speed detector 201 is installed in the middle position of the fixed plate 2 through the fixed frame. The input end of the wind speed detector 201 extends to the outside of the fixed plate 2 and is located in the cross frame 101. The fan blades 202 are also located on the outside of the fixed plate 2 for detecting the airflow velocity.

[0039] See also Figures 2 to 6The top of the fixing plate 2 is located on the side of the controller 3 and is equipped with a suction cup 203. The height of the suction cup 203 is greater than the height of the controller 3. The suction cup 203 supports the auxiliary fixing plate 601 to prevent the auxiliary fixing plate 601 from being squeezed on the controller 3 and reduce the folding and squeezing of the connecting line. The top of the fixing plate 2 is equipped with a first connecting seat 204. The adjusting cylinder 4 is rotatably connected to the first connecting seat 204. Two sets of baffles 602 are provided on the side of the auxiliary fixing plate 601, and a second connecting seat 603 is installed between the two sets of baffles 602. The adjusting cylinder 4 The output end is rotatably connected to the second connecting seat 603, which is convenient for adjusting the angle of the adjustment cylinder 4. The top and bottom ends of the baffle 602 are installed with adsorption metal plates 604. The output rod of the adjustment cylinder 4 is installed with a fixed electromagnet 401, and the output ends of the fixed electromagnet 401 have two output ends, and the output ends of the fixed electromagnet 401 extend to the top and bottom of the output end of the adjustment cylinder 4. When the sub-fixed plate 601 is rotated to a horizontal position, the fixed electromagnet 401 fits with the adsorption metal plate 604, which can further limit the sub-fixed plate 601.

[0040] See also Figures 7 to 9 , which is the second embodiment of the present application. The difference from the first embodiment is that a guide plate 7 is installed in the heat dissipation slot 605, specifically, the guide plate 7 is installed inside the heat dissipation slot 605, the guide plate 7 is located in the middle position of the heat dissipation slot 605, and a counterweight block 701 is provided at the bottom end of the guide plate 7, and an inclined surface 702 is provided at the top and bottom ends of the guide plate 7. When the secondary fixed plate 601 rotates, the guide plate 7 will rotate synchronously due to the center of gravity of the counterweight block 701, and can guide the direction of the airflow when the secondary fixed plate 601 rotates, so that the airflow flows from the inclined surface 702 above the guide plate 7, so that the airflow pushes the secondary fixed plate 601 to move downward, and further limits and fixes the secondary fixed plate 601.

[0041] During use of the present invention, the support frame 1 is first installed on the road surface, and the support frame 1 is fixed by the mounting seat 102, and then the fixing plate 2 is placed on the support frame 1, and each component is installed in the fixing plate 2, and the fixing plate 2 is symmetrically installed at the top and bottom of the support frame 1, and then the main display screen 5 is fixed on the cross bar 104 by bolts. At this time, the top and bottom of the main display screen 5 are aligned with the outer side of the cross bar 104, and then the auxiliary display screen 6 is installed at the top and bottom of the main display screen 5, and the auxiliary display screen 6 is limited by the bearing 502, and the output end of the adjustment cylinder 4 is fixed to the second connecting seat 603 on the back of the auxiliary display screen 6, so as to limit the two groups of auxiliary display screens 6;

[0042] During use, the main display screen 5 and the two sets of auxiliary display screens 6 are used to display the road conditions (such as construction, whether the road is passable, which road it belongs to, whether it is possible to turn around, etc.), and the main fixing plate 501 and the auxiliary fixing plate 601 are both provided with slots inside, so that air can pass through the main fixing plate 501 and the auxiliary fixing plate 601, thereby improving the heat dissipation effect of the main display screen 5 and the auxiliary display screen 6;

[0043] When encountering strong winds and extreme weather, the airflow blows from the fixed plate 2 to the auxiliary display screen 6. At this time, the airflow will also synchronously drive the fan blades 202 to rotate. The wind speed detector 201 detects the wind speed. If the wind speed is less than a predetermined value, the adjustment cylinder 4 limits the auxiliary display screen 6. When the wind force is greater than the predetermined value, the adjustment cylinder 4 is started, and the output end of the adjustment cylinder 4 extends out, thereby pushing the auxiliary display screen 6 to rotate along the wind force direction until the angle of the auxiliary display screen 6 remains horizontal. At this time, a group of adsorption metal plates 604 are attached to the bottom of the fixed electromagnet 401 to further fix the auxiliary display screen 6. At this time, the wind can be discharged from the heat dissipation slots 605 opened in the auxiliary fixed plate 601, thereby reducing the contact area between the auxiliary fixed plate 601 and the airflow, thereby reducing the wind force on the auxiliary display screen 6 and protecting the auxiliary display screen 6.

[0044] When the airflow is blown from the auxiliary display screen 6 to the fixed plate 2, the airflow will also drive the fan blades 202 to rotate, and the wind speed detector 201 will also detect the wind speed. When the wind speed is less than the predetermined value, the adjusting cylinder 4 will continue to limit the auxiliary display screen 6. When the wind force is greater than the predetermined value, the adjusting cylinder 4 will pull the auxiliary display screen 6 to rotate in the direction of the fixed plate 2, so that the auxiliary display screen 6 rotates along the wind force until the auxiliary display screen 6 is also rotated to the horizontal. At this time, a group of adsorption metal plates 604 are attached to the top of the fixed electromagnet 401, so as to further fix the auxiliary display screen 6. At this time, the wind is discharged from the heat dissipation slot 605, which reduces the contact area between the auxiliary fixed plate 601 and the airflow, reduces the wind force on the auxiliary display screen 6, and protects the auxiliary display screen 6.

[0045] When the wind force returns to a suitable range, the rotation speed of the fan blade 202 decreases. After the wind speed detector 201 detects that the wind force is less than a predetermined value for a certain period of time, the air hole of the adjusting cylinder 4 is opened. Driven by the reset spring 402, the auxiliary fixed plate 601 is rotated to a vertical position regardless of the direction in which it is rotated, and then the air hole of the adjusting cylinder 4 is closed to ensure that the auxiliary display screen 6 returns to its original position.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
