DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The intelligent network-connected luminous traffic sign is a traffic sign system that combines intelligent technology and luminous display technology. It can dynamically adjust and display according to real-time traffic conditions, weather conditions and road conditions, providing more effective traffic management and information transmission. This intelligent network-connected luminous traffic sign can be used in traffic scenes such as urban roads, highways, tunnels, bridges, etc., providing drivers and pedestrians with safer and more convenient traffic information services.

[0024] Example 1

[0025] In the existing device, rotating the screw rod can lift the walking wheel off the ground, so that the base and the connecting block can be completely in contact with the ground to improve stability. However, this method will cause the walking wheel to be uneven when the walking wheel is needed. The main reason is that manual rotation of multiple screw rods will cause the screw rods to rotate at different speeds and depths. The different screw rotation speeds and depths will affect the uneven contact between the walking wheel and the ground, which will lead to the problem of instability during the movement of the screen-lit traffic sign. Please refer to Figure 1-Figure 4 An embodiment provides an intelligent network-connected luminous traffic sign, including a display screen 1, four supporting legs 2 arranged at the bottom of the display screen 1, four walking wheels 3 are arranged inside the four supporting legs 2, and a connecting plate 21 is fixedly connected to the adjacent ends of the four supporting legs 2. A replacement mechanism 4 is provided on the top of the connecting plate 21 for driving the four walking wheels 3 to extend out of the four supporting legs 2 and contact the ground at the same time.

[0026] refer to Figure 2-Figure 4As shown, uneven contact between the four running wheels 3 and the ground may cause the connection line of the display screen 1 to loosen or break during movement, making it impossible to display content normally. In order to prevent the four running wheels 3 from being unevenly in contact with the ground during movement, causing the display screen 1 to be subjected to uneven force or vibration, the following settings are made: the replacement mechanism 4 includes a motor 41 fixed to the top of the connecting plate 21, the output end of the motor 41 is fixedly connected to a threaded rod 42, the outer wall of the threaded rod 42 is threadedly connected to a mounting sleeve 43, the circumferential surface of the mounting sleeve 43 is movably connected to a driving rod 44, and the end of the driving rod 44 away from the mounting sleeve 43 is movably connected to a limiting block 45, a rectangular groove is provided on the top of the supporting leg 2, and the limiting block 45 slides inside the rectangular groove to limit the limiting block 45, a connecting rod 46 is fixedly connected to the side of the limiting block 45, and a pressing plate 47 is fixedly connected to the end of the connecting rod 46 away from the limiting block 45, and a sliding block 48 is provided in the inner sliding sleeve of the supporting leg 2. The motor 41 drives the output end to drive the threaded rod 42 to rotate, causing the mounting sleeve 43 to move downward on the outer wall of the threaded rod 42, so that the driving rod 44 pushes the limit block 45, thereby causing the pressure plate 47 to move and abut against the sliding block 48. A limit groove is provided inside the support leg 2, and a slider is slidably connected inside the limit groove. The bottom of the slider is fixedly connected to an elastic sheet 49 fixedly connected to the bottom wall of the limit groove. The sliding block 48 is forced to move downward, causing the slider to slide down in the slide groove and squeeze the elastic sheet 49. The function of the elastic sheet 49 is to push the sliding block 48 to reset when there is no pressure to squeeze the sliding block 48. The top of the sliding block 48 is arranged in an inclined surface, and the side of the pressure plate 47 away from the connecting rod 46 contacts the inclined surface of the sliding block 48. The walking wheel 3 is movably connected to the bottom of the sliding block 48. During this process, the walking wheel 3 gradually protrudes out of the support leg 2, so that the uniformity of the contact between the walking wheel 3 and the ground is guaranteed, thereby improving the stability of the display screen 1 during movement.

[0027] refer to Figure 4 As shown, the top end of the threaded rod 42 is rotatably connected to a partition 5, the bottom of the partition 5 is fixedly connected to a support rod 51 fixedly connected to the top of the connecting plate 21, the top of the partition 5 is fixedly connected to a cylinder 6, the telescopic end of the cylinder 6 is fixedly connected to a lifting rod 7 fixedly connected to the bottom of the display screen 1, and starting the cylinder 6 so that the telescopic end pushes the lifting rod 7 can adjust the height of the display screen 1, so that the display screen 1 can be flexibly adjusted according to different usage scenarios and needs.

[0028] Example 2

[0029] Based on Example 1, Figure 4When the air pressure in the cylinder 6 is unstable or too low, the cylinder 6 cannot work normally, resulting in a sudden drop. In order to prevent the cylinder 6 from malfunctioning after adjusting the height of the display screen 1 and causing a sudden drop, so that the display screen 1 cannot be supported and there is a risk of damage to the display screen 1, such as tipping, falling or other damage, the following settings are made. The height of the display screen 1 is adjusted. The outer wall of the lifting rod 7 is provided with a protective component 8 for preventing the telescopic end of the cylinder 6 from falling suddenly. The protective component 8 includes a vertical plate 81 fixed to the top of the partition 5. The side of the vertical plate 81 close to the lifting rod 7 is fixedly connected to a sliding rod 82. The outer wall sliding sleeve of the sliding rod 82 is provided with a sliding sleeve 83. The outer wall of the sliding rod 82 is provided with a sliding rail. The inner wall of the sliding sleeve 83 is fixedly connected with a slider. The slider slides laterally in the track of the sliding rail to play a limiting role. The outer wall of the sliding sleeve 83 is sleeved with a spring 84, and the two ends of the spring 84 are fixedly connected to the vertical plate 81 and the sliding sleeve 83 respectively. The end of the sliding sleeve 83 away from the vertical plate 81 is fixedly connected to an electromagnet 85. The outer wall of the lifting rod 7 is vertically equidistantly provided with three gear slots 86, and the inner side walls of the three gear slots 86 are fixedly connected to magnets 87. When the electromagnet 85 is energized, it repels the magnet 87. After the height of the display screen 1 is adjusted, the power supply of the electromagnet 85 is disconnected. At this time, no repulsive force can be generated between the electromagnet 85 and the magnet 87, and the electromagnet 85 is placed in one of the gear slots 86 through the elasticity of the spring 84 to engage with it, thereby locking the lifting rod 7, thereby preventing the telescopic end of the cylinder 6 from suddenly falling and causing damage to the structure of the display screen 1 or electronic components.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
