Technical Field

[0001] The utility model relates to the technical field of traffic signs, in particular to a wind-resistant traffic sign. Background Art

[0002] Traffic sign structures are widely distributed on roads, bridges and other structures. With the rapid development of road construction in my country, the number and types of sign structures are increasing, and the service life requirements of sign boards are also getting higher and higher. Traffic signs are an important part of road traffic management and guidance. They not only provide directions, warnings and information, but also play a key role in ensuring traffic safety. However, in actual applications, traffic signs often face various challenges from the natural environment, among which the impact of wind is particularly prominent.

[0003] Strong winds can not only cause the toppling of traffic signs, but can also damage the structure of the signs. In severe cases, they can even cause traffic accidents, threatening people's lives and property. According to statistics, there are quite a few accidents caused by the toppling of traffic signs every year, which makes improving the wind resistance of traffic signs an urgent problem to be solved. The wind resistance of traffic signs is directly related to their design and structure. Traditional traffic signs are generally installed in a fixed manner. When encountering strong winds, the body of the sign, as the windward side, directly bears the impact of the wind. Due to the large area of ​​the sign body, the proportion of wind load in the overall structure is also relatively large, which is the main factor causing the toppling of signs. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] Embodiment 1:

[0024] See also Figure 1 - Figure 4 In this embodiment, a wind-resistant traffic sign is involved, which is specifically used to improve the stability of traffic signs in an environment with strong winds, prevent them from falling over or being damaged in strong winds, and ensure the normal use of traffic signs and traffic safety. It specifically includes: a sign body 1, the sign body 1 is fixed by a supporting component 2, the sign body 1 includes a plurality of swing units 3, the swing unit 3 includes a panel 31 and a hinge seat 32 fixed to the rear end of the panel 31, the panel 31 is hinged to the supporting component 2 through the hinge seat 32 and swings around the hinge, and a gap is left between the panels 31 of adjacent swing units 3.

[0025] Specifically, in this embodiment, the design of the swing unit 3 enables the panel 31 to swing around the hinge under the action of wind, so as to reduce the angle between the wind direction and the surface of the panel 31, thereby reducing the windward area of ​​the panel 31, which not only reduces the wind load borne by the panel 31, but also reduces the wind pressure borne by the overall structure, thereby improving the stability of the sign. In addition, during the swinging process, the panel 31 can dynamically adjust the size of the gap between adjacent panels 31 of the swing unit 3. Specifically, when the wind acts on the panel 31, the panel 31 swings around the hinge seat 32, resulting in an increase in the gap between adjacent panels 31. This design allows airflow to flow through these gaps, thereby reducing the direct impact of wind on the sign.

[0026] The sign body 1 also includes a circle of frame 41 surrounding the outer circumference of the swing unit 3, and a gap is left between the panel 31 and the frame 41, ensuring that the panel 31 is not restricted by the frame 41 when swinging, and allowing airflow to flow through these gaps, further reducing the impact of wind on the sign body 1. The frame 41 is connected and fixed with a frame 42, making the structure of the sign body 1 more stable. The frame 42 is installed on the rod of the support component 2 through a clamp 5. Specifically, the frame 42 is provided with a groove 421, and a plurality of studs are provided in the groove 421. The studs pass through the opening of the clamp 5, and one end of the stud is screwed into a nut to fix the clamp 5. Through the tightening of the studs and nuts, the clamp 5 can be firmly connected to the frame 42 and the rod, ensuring the stability of the entire sign structure in strong winds. In this embodiment, the hinge seat 32 is fixed to the panel 31 by welding or screwing, and the frame 42 is fixed to the frame 41 by welding or screwing.

[0027] See also Figure 5 The frame 42 is provided with a U-shaped bending portion, a pin shaft 424 is provided in the bending portion, and the hinge seat 32 is provided with an axial hole 321 adapted to the pin shaft 424. The hinge seat 32 is sleeved on the outside of the pin shaft 424 through the axial hole 321, so that the hinge seat 32 can swing in the bending portion of the frame 42 through the pin shaft 424. The maximum swing angle (range) of the hinge seat 32 is limited when the bending portion contacts the extension plates 322 on both sides of the hinge seat 32. The panel 31 is hinged to the support component 2 through the hinge seat 32, so that the panel 31 can swing at a small angle (between -10° and 10°) around the hinge to maintain the readability of the card body 1.

[0028] See also Figure 6 , the hinge seat 32 is provided with elastic connectors 6 on both sides of the shaft hole 321, and the elastic connector 6 includes a spring 61, one end of the spring 61 is provided with a fixed block 62 fixedly connected to the hinge seat 32, and the other end is provided with a slider 63, and the bending portion is provided with a slide groove 425 adapted to the sliding connection with the slider 63. When the wind acts on the panel 31, the panel 31 swings around the hinge, driving the hinge seat 32 to rotate on the pin 424 through the shaft hole 321, the spring 61 is stretched or compressed, and the slider 63 slides in the slide groove 425, providing a buffering effect when the swinging part swings (when swinging, the hinge seat 32 and the bending portion collide) and absorbing part of the wind impact, thereby protecting the structure of the card body 1. In addition, when the wind decreases, under the action of the restoring force of the elastic connector 6, the panel 31 will automatically return to its original position, and the gap between adjacent panels 31 will be reduced, so that the front of the card body 1 is restored to be flat.

[0029] The support component 2 in this embodiment adopts an F-shaped structure, which includes a base 21 fixed to the ground, a vertical pole 22, and several groups (2 groups in this embodiment) of parallel horizontal arms 23 fixed to the vertical pole 22. The clamp 5 is sleeved and fitted with the horizontal arm 23, and the frame 42 is vertically arranged on the frame body 41.

[0030] The panel 31 is provided with a circle of ventilation notches 311 at the edge, so that the gap between adjacent swing units 3 is increased, thereby increasing the flow of wind from the gap, thereby reducing wind resistance and improving the wind resistance of the sign. The identification information is located in the middle area of ​​the panel 31, which ensures the ventilation of the sign while maintaining the readability of the sign. In this embodiment, the ventilation notches 311 on the side of the panel 31 between adjacent swing units 3 can be arranged in a staggered and complementary manner, which can improve the integrity of the sign body 1.

[0031] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
