Abstract
Description
Technical Field
[0001] The utility model relates to a wind-resistant road sign. Background Art
[0002] Highway signs are important road signs for people and are particularly important. Currently, highway signs are arranged in different shapes along both sides of the road. The existing highway signs have a relatively large indication surface, especially at high altitudes. The wind blows all year round, causing highway signs to be blown crooked or blown off, resulting in a large amount of maintenance work and high maintenance costs in the later stage of the road. Therefore, a sign with strong wind resistance is needed. Utility Model Content
[0003] The utility model provides a wind-resistant road sign, which can effectively solve the above problems.
[0004] The utility model is achieved in this way:
[0005] A wind-resistant road sign, comprising a support frame, a crossbar arranged on the support frame, and a sign body arranged at both ends of the support frame;
[0006] The sliding limit assembly includes a U-shaped block, a second slide groove arranged in the middle of the U-shaped block, a connecting block slidably arranged on the second slide groove, sliding blocks fixedly arranged on both sides of the connecting block, an elastic member fixedly arranged inside the second slide groove, limit plates fixedly arranged at both ends of the U-shaped block, a mounting block fixedly arranged at the top of the limit plate, an axle rod arranged between the mounting blocks, and a movable plate movably arranged on the axle rod, and one end of the movable plate is slidably connected to the first slide groove arranged on the sign body, so that the sign body can be reset after shaking left and right.
[0007] As a further improvement, the two U-shaped blocks and the connecting block form a through wind passage, so that the lateral wind can pass through the wind passage quickly.
[0008] As a further improvement, a first wind-breaking piece is fixedly provided on the top of the sign body, and a second wind-breaking piece is fixedly provided on both side surfaces of the sign body.
[0009] As a further improvement, the side edges of the first wind-breaking member and the second wind-breaking member both protrude from the sign body.
[0010] As a further improvement, the wind-breaking ends of the first wind-breaking member and the second wind-breaking member both have an angle A, wherein 30 degrees ≤ A ≤ 60 degrees.
[0011] As a further improvement, there is an initial angle B between the movable plate and the shaft rod, wherein 20 degrees ≤ B ≤ 35 degrees.
[0012] The beneficial effects of the utility model are:
[0013] (1) The utility model provides a sliding limit assembly to slide and pull the sign body, thereby effectively weakening the wind force and preventing the wind force from acting entirely on the sign board. This not only prevents the sign body from being damaged, but also reduces subsequent maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0026] Reference Figure 1-6 As shown, a wind-resistant road sign comprises a support frame 1, a crossbar 2 arranged on the support frame 1, and a sign body 3 arranged at both ends of the support frame 1.
[0027] The sliding limit assembly 5 includes a U-shaped block 50, a second slide groove 501 arranged in the middle of the U-shaped block 50, a connecting block 500 slidably arranged on the second slide groove 501, sliders 502 fixedly arranged on both sides of the connecting block 500, an elastic member 503 fixedly arranged inside the second slide groove 501, limit plates 51 fixedly arranged at both ends of the U-shaped block 50, mounting blocks 52 fixedly arranged at the top of the limit plates 51, an axle rod 53 arranged between the mounting blocks 52, and a movable plate 54 movably arranged on the axle rod 53, and one end of the movable plate 54 is slidably connected to the first slide groove 4 arranged on the card body 3, so that the card body 3 is reset after shaking left and right.
[0028] It should be noted that the connecting end of the shaft rod 53 and the movable plate 54 is movably connected, and a movable clearance hole (not shown in the figure) is provided at the connecting end of the movable plate 54 and the shaft rod 53, the aperture of which is larger than the outer diameter of the shaft rod 53, and the movable plate 54 is connected to the shaft rod 53 via the movable clearance hole. In actual application, the movable plate 54 will slide due to the first slide groove 4. During the sliding process, the aperture of the movable clearance hole will be smaller than the outer diameter of the shaft rod 53, which will cause the movable plate 54 to be restricted and unable to be used in conjunction with the connecting block 500.
[0029] Furthermore, the shape of the movable yielding hole is a long strip, a circle or a square, etc. As long as the yielding effect can be achieved, this case does not impose too many restrictions and can be selected according to actual needs.
[0030] There is an initial angle B between the movable plate 54 and the shaft 53, wherein 20 degrees ≤ B ≤ 35 degrees. In one embodiment, B is about 30 degrees. If B is too small, the card body 3 will not have a movable distance forward or backward, which will increase the rigidity of the card body 3 and cause damage to the card body 3; if B is too large, the movable distance of the card body 3 will be increased, causing metal fatigue when the card body 3 moves forward and backward.
[0031] In actual use, when the sign body 3 encounters side wind, the two U-shaped blocks 50 and the connecting block 500 form a through wind passage, so that the side wind can pass quickly through the wind passage, thereby reducing the intensity brought by the side wind and avoiding damage to the sign body 3. At the same time, second wind-breaking pieces 7 are fixedly provided on both sides of the sign body 3. The second wind-breaking pieces 7 can break the side wind, so that the side wind flows toward the two sides of the second wind-breaking pieces 7. Furthermore, the side edges of the second wind-breaking pieces 7 protrude from the sign body 3, and guide the side wind to the sides of the sign body 3, avoiding the side wind from directly acting on the sign body 3. At the same time, if the top of the sign body 3 is affected by the wind from above, the first wind-breaking piece 6 fixedly provided on the top of the sign body 3 can also play the same role as the second wind-breaking piece 7, thereby improving the stability of the sign body 3.
[0032] When the card body 3 is subjected to positive wind force, the wind force directly acts on the card body 3. At this time, the bottom of the card body 3 is connected to the connecting block 500, and the connecting block 500 and the U-shaped block 50 slide on the second slide groove 501 through the slider 502. The positive wind force acting on the card body 3 will drive the card body 3 to slide backward through the connecting block 500 and other structures. At this time, in order to prevent the positive wind from damaging the card body 3, the movable plate 54 on the back of the card body 3 will slide forward with the first slide groove 4, and the movable plate 54 set on the front of the card body 3 will slide slightly downward, so as to ensure that the card body 3 will not be damaged by the positive wind. Furthermore, when the connecting block 500 slides forward or backward, the elastic member 503 connected to the connecting block 500 can play a pulling and resetting effect to ensure that the card body 3 will not tilt after being subjected to force. Furthermore, a limiting plate 51 is also provided on the U-shaped block 50. After the card body 3 is subjected to force and moves, it can abut against the front and back sides of the card body 3 to prevent the card body 3 from separating from the U-shaped block 50.
[0033] Furthermore, by limiting the position of the movable plate 54 and the limiting plate 51 , the sign body 3 can be effectively prevented from being skewed, and at the same time, the damage rate of the sign body 3 is reduced.
[0034] The wind-breaking ends of the first wind-breaking member 6 and the second wind-breaking member 7 both have an angle A, which is 30 degrees ≤ A ≤ 60 degrees. In one implementation, A is about 35 degrees, so as to achieve a wind-breaking effect and prevent the wind from directly acting on the card body 3.
[0035] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
