Description
Technical Field
[0001] The utility model relates to the field of signboards, in particular to a signboard which can prevent falling over and strong winds. Background Art
[0002] Wind has both size and direction, so the wind forecast includes wind speed and direction. The size of wind speed is usually expressed by several wind levels, and the wind level is determined according to the degree of impact of the wind on ground objects. When strong winds occur, large branches shake, electric wires whistle, and it is difficult to walk with an umbrella. The huge thrust of the strong wind causes objects on the road to be blown down, making these objects lose their original function.
[0003] Movable road warning signs can remind people of specific information. They are composed of support columns and signboards and are placed on the road to provide safety warnings, prohibited passage and other information. Signs help to provide road information and protect people's lives and property.
[0004] In strong wind weather, signboards are often blown down due to the large-scale thrust of strong winds, resulting in the loss or damage of signboards after strong wind weather. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a signboard that can prevent falling over and strong winds, so as to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a signboard that can prevent falling over and strong winds, comprising a frame, a connecting rod fixedly installed on the outer wall of the frame, and the signboard is rotatably installed on the outer wall of the connecting rod, and a slider is fixedly installed on the end of the signboard, a sliding groove corresponding to the slider is opened in the frame, and a limit block corresponding to the slider is installed in the sliding groove, and a spring corresponding to the slider is installed in the sliding groove, two guide columns are fixedly installed in the sliding groove, and the end of the second guide column is fixedly installed with a first guide column slidably connected to the slider.
[0007] By adopting the above technical solution, the signboards are evenly spaced and guide rods and springs are set inside the frame to restrict the signboards. Under the huge thrust of strong winds, the dispersedly arranged signboards allow the wind to disperse and pass through the spacing between the signboards, reducing the thrust of the wind. At the same time, as the wind force increases, the signboards drive the limit blocks to begin to squeeze the springs, causing the signboards to begin to rotate, thereby increasing the spacing between the signboards and allowing more wind to pass through the spacing, further reducing the thrust of the strong wind, thereby reducing the thrust on the frame and reducing the occurrence of signboards being blown down due to strong winds.
[0008] The utility model is further configured that a plurality of identification plates are installed at equal intervals on the outer wall of the frame, and the distance between the identification plates is 3MM.
[0009] By adopting the above technical solution, the wind can pass through the gaps between the identification plates, so that the thrust of the frame received by the wind is reduced.
[0010] The utility model is further configured that the middle and lower position of the identification plate is connected to the connecting rod, and the angle between the identification plate and the frame is degrees.
[0011] By adopting the above technical solution, the rotation amplitude of the signboard is increased, thereby dispersing the thrust of the wind.
[0012] The utility model is further configured such that the cross section of the first guide column is designed as a semicircular ring, and the cross section of the second guide column is a rectangle.
[0013] By adopting the above technical solution, the spring can press the slider under the restriction of the first guide column.
[0014] The utility model is further configured such that the diameter of the second guide column is equal to that of the first guide column, and the second guide columns are arranged at both ends of the first guide column.
[0015] By adopting the above technical solution, the spring can be smoothly retracted into the second guide column when being squeezed by the slider.
[0016] The utility model is further configured that two groups of springs are symmetrically arranged in the limit block, and the ends of the springs are in contact with the outer wall of the slider.
[0017] By adopting the above technical solution, when the slider moves left and right in the slide groove, it can be reset by the squeezing of the spring so that the slider can be always squeezed by the spring.
[0018] The utility model is further configured that two groups of limit blocks are symmetrically arranged in the slide groove, and the width of the slide block is greater than the distance between the limit blocks.
[0019] By adopting the above technical solution, the slider will no longer move under the restriction of the limit blocks, and the slider will not slide into between the limit blocks.
[0020] The utility model is further configured that the spring is sleeved on the outer walls of the first guide column and the second guide column, and the diameter of the spring is smaller than the spacing between the limit blocks.
[0021] By adopting the above technical solution, the spring is contracted in the slide groove under the guidance of the first guide column and the second guide column, so that the spring can be smoothly contracted into between the limit blocks.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] The utility model is provided with springs, limit blocks, and guide columns, and the signboards are evenly spaced. At the same time, guide rods and springs are provided inside the frame to limit the signboards. Under the huge thrust of strong winds, the dispersedly arranged signboards allow the wind to disperse and pass through the spacing between the signboards, thereby reducing the thrust of the wind. At the same time, as the wind force increases, the signboards drive the limit blocks to begin to squeeze the springs, causing the signboards to begin to rotate, thereby increasing the spacing between the signboards, allowing more wind to pass through the spacing, further reducing the thrust of the strong wind, thereby reducing the thrust on the frame, and reducing the occurrence of the signboards being blown down due to strong winds.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0032] The following describes an embodiment of the utility model based on its overall structure.
[0033] A sign that can prevent falling over and strong winds, such as Figure 1 - Figure 6As shown, it includes a frame 1, a connecting rod 2 is fixedly installed on the outer wall of the frame 1, and an identification plate 3 is rotatably installed on the outer wall of the connecting rod 2. As the wind force gradually increases, the identification plate 3 is squeezed more and more, and the identification plate 3 rotates on the outer wall of the connecting rod 2, and a slider 4 is fixedly installed on the end of the identification plate 3. A slide groove 9 corresponding to the slider 4 is opened in the frame 1, and the identification plate 3 drives the slider 4 connected at the end to slide in the slide groove 9, and a limit block 8 corresponding to the slider 4 is installed in the slide groove 9. As the identification plate 3 continues to rotate, the slider 4 continues to squeeze the spring 5, and finally the outer wall of the slider 4 is attached to the end of the limit block 8. Under the restriction of the limit block 8, the identification plate 3 no longer rotates, and the slide groove 9 A spring 5 corresponding to the slider 4 is installed inside, a second guide column 7 is fixedly installed in the slide groove 9, and a first guide column 6 slidably connected to the slider 4 is fixedly installed on the end of the second guide column 7. The slider 4 squeezes the spring 5, and the spring 5 shrinks toward the second guide column 7 under the restriction of the first guide column 6. At this time, the distance between the ends of the sign 3 increases, so that more wind passes through the gap, and the wind force applied to the frame 1 is reduced. The spring 5 shrinks into the limit block 8. At this time, the distance between the ends of the sign 3 reaches the maximum, and the wind force applied to the sign 3 is the smallest, and then the thrust applied to the frame 1 is reduced again. At this time, the frame 1 is prevented from being blown down in strong wind weather, as the wind force decreases.
[0034] See also Figure 1 and Figure 2 There are multiple signboards 3 installed at equal intervals on the outer wall of the frame 1. When the wind blows towards the signboards 3, the wind will pass through the gaps between the signboards 3 due to the equal spacing between the signboards 3. The distance between the signboards 3 is 3MM, so that the signboards are spaced apart without affecting the displayed content, so that the thrust of the wind on the frame 1 is reduced.
[0035] See also Figure 1 - Figure 3 The lower middle position of the sign 3 is connected to the connecting rod 2, and the angle between the sign 3 and the frame 1 is 5 degrees. When the sign 3 is subjected to the thrust of the wind, the sign 3 starts to rotate, and the distance between the sign 3 becomes larger, making the rotation amplitude of the sign 3 larger, thereby dispersing the thrust of the wind.
[0036] See also Figure 4 and Figure 6 The cross section of the first guide column 6 is designed as a semicircular ring. When the slider 4 moves in the slide groove 9, the spring 5 is squeezed. Through the restriction of the first guide column 6, the spring 5 is squeezed into between the limit blocks 8 by the slider 4. The cross section of the second guide column 7 is a rectangle, so that the spring 5 can squeeze the slider 4 under the restriction of the first guide column 6.
[0037] See also Figure 6The second guide column 7 has the same diameter as the first guide column 6, so that the spring 5 can be smoothly retracted into the second guide column 7 when squeezed by the slider 4, and the second guide columns 7 are provided at both ends of the first guide column 6. When the slider 4 slides in the slide groove 9, it can move to the two ends of the first guide column 6.
[0038] See also Figure 6 Two groups of springs 5 are symmetrically arranged in the limit block 8, so that when the slider 4 moves left and right in the slide groove 9, it can be reset by the compression of the spring 5, and the end of the spring 5 contacts the outer wall of the slider 4, so that the slider 4 can be always compressed by the spring 5.
[0039] See also Figure 6 There are two groups of limit blocks 8 symmetrically arranged in the slide groove 9. The identification plate 3 drives the slider 4 when rotating. When the slider 4 moves to the end of the first guide column 6, the limit block 8 restricts the slider 4 so that the slider 4 no longer moves under the restriction of the limit block 8. The width of the slider 4 is greater than the distance between the limit blocks 8, so that the slider 4 will not slide between the limit blocks 8.
[0040] See also Figure 6 The spring 5 is sleeved on the outer wall of the first guide column 6 and the second guide column 7, so that the spring 5 is contracted in the slide groove 9 under the guidance of the first guide column 6 and the second guide column 7, and the diameter of the spring 5 is smaller than the spacing between the limit blocks 8. When the slider 4 squeezes the spring 5, the spring 5 contracts into the space between the limit blocks 8, so that the spring 5 can be smoothly contracted into the space between the limit blocks 8.
[0041] The working principle of the utility model is as follows: when strong wind weather occurs, the wind force will gradually increase. At this time, the wind force will squeeze the signboard 3. Due to the gap between the signboards 3, the wind will pass through the gap, thereby reducing the thrust exerted on the frame 1. As the wind force gradually increases, the signboard 3 is squeezed more and more. At this time, the signboard 3 rotates on the outer wall of the connecting rod 2, and the signboard 3 drives the slider 4 connected to the end to slide in the slide groove 9. The slider 4 squeezes the spring 5. The spring 5 contracts toward the second guide column 7 under the restriction of the first guide column 6. At this time, the distance between the ends of the signboard 3 increases, allowing more wind to pass through the gap. At this time, the wind force exerted on the frame 1 is reduced. As the signboard 3 continues to rotate, the slider 4 continues to squeeze the spring 5, and finally the slide The outer wall of block 4 is in contact with the end of limit block 8. Under the restriction of limit block 8, sign board 3 no longer rotates, and spring 5 contracts into limit block 8. At this time, the distance between the ends of sign board 3 reaches the maximum, and the wind force received by sign board 3 is the smallest, and then the thrust received by frame 1 is reduced again. At this time, frame 1 is prevented from being blown down in strong wind weather. As the wind force decreases, the wind force received by sign board 3 is also reduced. At this time, slider 4 begins to slide in slide groove 9 under the action of spring 5, thereby driving sign board 3 to rotate, sign board 3 is gradually reset, and the distance between sign boards 3 is reduced. As the wind force is dispersed by the gaps between sign boards 3, a huge thrust on frame 1 due to strong wind weather is avoided, thereby preventing frame 1 from being blown down by strong wind.
