Description
Technical Field
[0001] This utility model relates to the technical field of road warning devices, and in particular to a road icing warning device. Background Technology
[0002] In winter, low temperatures and icy roads pose a significant threat to transportation safety, easily causing vehicles to skid and lose control, and increasing braking distances, thus seriously threatening the lives of drivers, passengers, and pedestrians. Statistics show that the accident rate increases significantly in icy and snowy weather conditions compared to normal weather. Road icing warning devices, as key facilities for ensuring road traffic safety in winter, can detect environmental changes in advance and issue timely warnings to passing vehicles and pedestrians, providing important support for preventing traffic accidents and managing traffic flow.
[0003] Existing road icing warning devices are mostly fixed structures, where warning signs are directly welded or bolted to support columns. Their height is determined during installation and cannot be adjusted according to actual needs. Some devices use bolt and nut adjustment structures, with multiple bolt holes of different heights set on the support columns. The warning signs are fixed to the corresponding height holes by tightening the bolts.
[0004] However, existing road icing warning devices suffer from the problem of inconvenient height adjustment. Fixed-structure warning devices, once installed, cannot adjust the warning sign height according to actual road conditions and vehicle height changes. The fixed height of the warning sign makes it difficult for passing drivers to see, significantly reducing its warning effectiveness. Devices using bolt and nut adjustment mechanisms require tools for each adjustment, consuming considerable time and manpower. Furthermore, in cold weather, operators must handle the bolts and nuts by hand, which is not only inconvenient but also increases the risk of frostbite. In emergency situations, such as temporary road construction altering vehicle routes and requiring rapid adjustment of the warning sign height, this method cannot meet the timeliness requirements and is difficult to widely apply. Therefore, a new road icing warning device is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a road icing warning device, which aims to improve the existing technology's inability to adjust the height of warning signs according to actual road conditions and vehicle height changes, thus failing to meet timeliness requirements and making it difficult to be widely used.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A road icing warning device includes a fixed frame, a support base fixedly connected to the outer wall of the fixed frame, a temperature sensor disposed inside the fixed frame, a support frame fixedly connected to the top of the fixed frame, a sliding rod slidably connected inside the support frame, a support frame fixedly connected to the top of the sliding rod, a warning sign disposed on the top of the support frame, a warning light disposed on the side wall of the warning sign, a fixing ring fixedly connected to one side of the support frame, a positioning component disposed inside the support frame, and a connecting component disposed on one side of the warning sign.
[0008] The positioning component includes a pin, which is slidably connected inside the support frame and the fixing ring. One end of the pin is fixedly connected to a connecting ring, and one end of the connecting ring is fixedly connected to a pull ring. A spring is sleeved on the outer wall of the pin, and the two ends of the spring are respectively fixedly connected inside the warning sign and the connecting ring. A positioning hole is opened inside the slide rod, and the pin is slidably connected inside the positioning hole.
[0009] As a further description of the above technical solution:
[0010] The connecting assembly includes a fixing block and an insert block. One side of the fixing block is fixedly connected to one side of the warning sign, and the top of the insert block is fixedly connected to the bottom of the fixing block.
[0011] As a further description of the above technical solution:
[0012] A second connecting frame is fixedly connected to one side of the support frame, and the insert block is slidably connected inside the second connecting frame.
[0013] As a further description of the above technical solution:
[0014] The insert has symmetrically connected sliders inside, and a telescopic column is provided between the two sliders.
[0015] As a further description of the above technical solution:
[0016] The telescopic column is fitted with a second spring, and the two ends of the second spring are respectively fixedly connected to the inside of the two sliders.
[0017] As a further description of the above technical solution:
[0018] The connecting frame 2 has symmetrical push-pull rods that slide inside. Each of the two push-pull rods has a baffle fixedly connected to one side, and each of the two baffles has a limit block fixedly connected to one side.
[0019] As a further description of the above technical solution:
[0020] A connecting frame is fixedly connected to the top of the support frame, and the warning sign is slidably connected inside the connecting frame.
[0021] As a further description of the above technical solution:
[0022] A threaded post is provided inside the first connecting frame. The threaded post passes through the warning sign and the first connecting frame. A nut is threadedly connected to the outer wall of the threaded post.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by pulling the pull ring, the connecting ring and the pin overcome the spring force and are pulled out of the positioning hole of the slide rod. At this time, the position of the slide rod in the support frame can be moved freely. After adjusting to a suitable height, the pull ring is released, and the spring force causes the pin to re-insert into the positioning hole, thereby fixing the height of the slide rod and the warning sign. This achieves the effect of conveniently adjusting the height of the warning sign, solving the problem that the height of the warning sign cannot be adjusted according to the actual road conditions and changes in vehicle height, thus failing to meet the timeliness requirements and making it difficult to be widely used. This improves the applicability of the warning device.
[0025] 2. In this utility model, by inserting the bottom of the warning sign into the connecting frame one at the top of the support frame, and simultaneously making the fixing block fit into the connecting frame two, when the insert block is inserted into the connecting frame two, the slider slides under force and compresses the spring. After the spring returns to its original position, the slider makes tight contact with the inner wall of the connecting frame two to achieve a stable connection. When disassembling, pressing the push-pull rod drives the limiting block to squeeze the slider and make it detach. Furthermore, the warning sign and the connecting frame one are inserted through the threaded post and further fixed with the nut. This achieves the effect of quick disassembly and assembly of the warning sign, solving the problems of cumbersome disassembly and assembly, time-consuming and labor-intensive disassembly and assembly, and difficulty in quick replacement or maintenance of the warning sign in traditional warning devices, thereby improving the flexibility of the warning device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1-3 This utility model provides an embodiment of a road icing warning device, including a fixed frame 1, a support base 2 fixedly connected to the outer wall of the fixed frame 1, a temperature sensor (Pt100 resistance temperature sensor) inside the fixed frame 1, which can accurately detect minute changes close to the critical temperature for road icing and issue a timely warning (this is prior art and will not be described in detail here), a support frame 3 fixedly connected to the top of the fixed frame 1, a sliding rod 4 slidably connected inside the support frame 3, the sliding rod 4 having a certain degree of sliding freedom, allowing the support frame 5 to adjust its position as needed, thereby optimizing the visibility of the warning sign 24 and the effect of transmitting warning information, a support frame 5 fixedly connected to the top of the sliding rod 4, a warning sign 24 set on the top of the support frame 5, a warning light 25 set on the side wall of the warning sign 24, a fixed ring 6 fixedly connected to one side of the support frame 3, a positioning component inside the support frame 3, and a connecting component set on one side of the warning sign 24;
[0035] The positioning component includes a pin 7, which is slidably connected inside the support frame 3 and the fixing ring 6. One end of the pin 7 is fixedly connected to a connecting ring 8, and the other end of the connecting ring 8 is fixedly connected to a pull ring 9. When the pull ring 9 is pulled, the connecting ring 8 and the pin 7 can overcome the elastic force of the spring 10 and thus be pulled out from the positioning hole 11 of the slide rod 4, unlocking the fixed state of the slide rod 4. The outer wall of the pin 7 is fitted with a spring 10, and the two ends of the spring 10 are fixedly connected to the warning sign 24 and the connecting ring 8, respectively. The slide rod 4 has a positioning hole 11 inside, and the pin 7 is slidably connected inside the positioning hole 11. When the pull ring 9 is released, the elastic force of the spring 10 will cause the pin 7 to automatically re-insert into the positioning hole 11, thereby fixing the height of the slide rod 4. The spring 10 plays a crucial role in this process, providing the necessary reaction force to ensure that the fixed height of the slide rod 4 and the warning sign 24 can be stably maintained after adjustment.
[0036] Reference Figure 1 , Figure 4 and Figure 5 The connecting assembly includes a fixing block 16 and an insert block 17. The fixing block 16 is fixedly connected to one side of the warning sign 24, and the top of the insert block 17 is fixedly connected to the bottom of the fixing block 16. A connecting frame 15 is fixedly connected to one side of the support frame 5. The insert block 17 is slidably connected inside the connecting frame 15. Symmetrical sliders 18 are slidably connected inside the insert block 17. A telescopic post 19 is provided between the two sliders 18. A spring 20 is fitted on the outer wall of the telescopic post 19. Both ends of the spring 20 are fixedly connected inside the two sliders 18, and the two sliders 18 are connected by the telescopic post 19. The spring 20 serves to adjust the telescopic post 19, allowing the insert block 17 to be adjusted as needed. Symmetrical push-pull rods 2 are slidably connected inside the connecting frame 15. 1. Each of the two push-pull rods 21 has a baffle 22 fixedly connected to one side, and each of the two baffles 22 has a limit block 23 fixedly connected to one side. When disassembling the warning sign 24, the user only needs to press the push-pull rod 21, so that the limit block 23 will slide in the connecting frame 2 15 and squeeze the slider 18. The slider 18 will then disengage from the connecting frame 2 15, completing the disassembly process. This ensures the ease and stability of operation. The top of the support frame 5 is fixedly connected to the connecting frame 1 14. The warning sign 24 is slidably connected inside the connecting frame 1 14. The connecting frame 1 14 is provided with a threaded post 12. The threaded post 12 passes through the warning sign 24 and the connecting frame 1 14. The outer wall of the threaded post 12 is threaded with a nut 13. The structural design of the threaded post 12 and the nut 13 ensures that the device can maintain a stable fixing effect during long-term use.
[0037] Working principle: When using this road icing warning device, the ambient temperature is monitored in real time by the temperature sensor in the fixed frame 1. When the temperature drops to near or reaches the critical value at which the road may ic, the temperature sensor transmits a signal to the relevant control unit, triggering the warning light 25 on the warning sign 24 to light up, so as to warn passing vehicles and pedestrians to pay attention to the road icing situation. When it is necessary to adjust the height of the warning sign 24, pull the pull ring 9, which drives the connecting ring 8 and the pin 7 to overcome the elastic force of the spring 10 and pull them out of the positioning hole 11 of the slide rod 4. At this time, the position of the slide rod 4 in the support frame 3 can be moved up and down. After adjusting to a suitable height, release the pull ring 9. Under the elastic force of the spring 10, the pin 7 is reinserted into the positioning hole 11, so as to fix the height of the slide rod 4 and the warning sign 24, thereby achieving the effect of facilitating the adjustment of the warning height.
[0038] When it is necessary to disassemble or assemble the warning sign 24, first insert the bottom of the warning sign 24 into the connecting frame 14 at the top of the support frame 5. At the same time, the fixing block 16 on one side of the warning sign 24 is attached to the top of the connecting frame 25. During this process, the insert block 17 is inserted into the connecting frame 25, so that the slider 18 is subjected to force and slides in the insert block 17 and compresses the spring 20. When the insert block 17 is fully inserted, the spring 20 returns to its original position, so that the slider 18 is in close contact with the inner wall of the connecting frame 25, thus achieving a stable connection between the insert block 17 and the connecting frame 25. When disassembling, simply press the push-pull rod 21 to make it slide the limiting block 23 in the connecting frame 25. At the same time, the limiting block 23 squeezes the slider 18, making it disengage from the connecting frame 25 to complete the disassembly. At the same time, threaded post 12 is inserted into the warning sign 24 and the connecting frame 14, and the nut 13 is tightened to further fix the warning sign 24 on the support frame 5, thereby achieving the effect of easy disassembly and assembly of the warning sign 24.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
