[0002] On the road, it is often necessary to use height limit frames to limit the loading height of trucks. For example, on highways, culverts, bridges and roads crossing under railways, height limit frames are needed to ensure driving safety.

[0003] Currently, the most common height limit frame is a horizontal bar with a rigid height limit. Although it can prevent overheight vehicles from passing through, it is not effective in providing height limit warning for vehicles. Vehicles often collide with the height limit frame due to driver misjudgment of height or distraction. When a vehicle hits the height limit frame, it will cause serious damage to both the vehicle and the height limit frame. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an improved height limit warning device, which solves the problem that the height limit warning effect of the vehicle is not enough, and the vehicle often collides with the height limit frame or the vehicle hits the height limit frame due to the driver's misjudgment of height or distraction, causing serious damage to the vehicle and the height limit frame.

[0011] Beneficial Effects

[0012] The utility model provides an improved height limit warning device. Compared with the existing technology, it has the following beneficial effects:

[0013] (1) The utility model uses a reflective tape arranged in front of the height limit frame. If the vehicle is overheight, it will push the reflective tape, and the reflective tape will pull the sliding block to move through the sliding frame. The sliding block will no longer squeeze the sliding plate through the squeezing block. Through the action of the second spring, the sliding plate presses the control button, so that the two control buttons control the alarm to sound an alarm. The alarm will warn the vehicle driver again, which can effectively prompt the vehicle driver to slow down and stop, thereby effectively improving the height limit warning effect of the vehicle.

[0014] (2) In the utility model, if a vehicle continues to travel after exceeding the height limit, the vehicle will collide with the height limit plate, and the height limit plate will squeeze the inclined surface of the inclined plate, so that the inclined plate moves into the supporting plate through the first spring. The two inclined plates no longer resist the height limit plate, so that the vehicle quickly separates from between the two fixing rods when colliding with the height limit plate, thereby being able to well reduce the impact force of the vehicle colliding with the height limit frame, and effectively reduce the degree of damage caused by the vehicle collision.

[0021] See also Figure 1-4 The utility model provides a technical solution: an improved height limit warning device, including a height limit frame 1, warning plates 2 are fixedly connected to the upper part of both sides of the front of the height limit frame 1, a strip groove 3 is opened on the top of the warning plate 2, a sliding block 4 is slidably connected inside the strip groove 3, a sliding frame 5 is fixedly connected to the top of the sliding block 4, a reflective tape 6 is fixedly installed between the opposite sides of the two sliding frames 5, an extrusion block 7 and a first magnet block 8 are fixedly connected to the upper and lower parts of the front of the sliding block 4, and a second magnet adapted to the first magnet block 8 is fixedly installed on the front of the inner cavity of the strip groove 3 Block 9, as a detailed explanation, the first magnet block 8 and the second magnet block 9 are attracted to each other by opposite poles, a control button 10 is fixedly installed on one side of the inner cavity of the strip groove 3 through a connecting block, and an alarm 11 adapted to the control button 10 is fixedly installed on the top of the height limit frame 1. The alarm 11 is electrically connected to an external power supply and is controlled by the control button 10. If the extrusion block 7 no longer presses the control button 10, the alarm 11 will be turned on, and a sliding plate 24 is slidably connected between the two sides of the inner cavity of the strip groove 3, and a second spring 25 is fixedly connected between the front part of the sliding plate 24 and the inner wall of the strip groove 3.

[0022] It should be noted that, due to the oppositely charged attraction between the first magnet block 8 and the second magnet block 9 , the sliding block 4 drives the pressing block 7 to push the sliding plate 24 , so that the sliding plate 24 moves inward without pressing the control button 10 .

[0023] Furthermore, in order to display information on the height limit frame 1, an information display screen 22 is fixedly installed on the top of the height limit plate 13, and a plurality of warning lights 23 are fixedly installed on the front of the fixed rod 12. The warning lights 23 are electrically connected to an external power supply and controlled by a control switch.

[0024] Furthermore, in order to reduce the impact force of the vehicle colliding with the height limit frame 1, the height limit frame 1 includes two fixed rods 12 and a height limit plate 13. The upper parts of the two fixed rods 12 on opposite sides are fixedly connected with support plates 14 that are compatible with the height limit plate 13. The top of the support plate 14 and the front part of the height limit plate 13 are fixedly connected with a limiting plate 15. The top of the support plate 14 and the rear part of the height limit plate 13 are slidably connected with an inclined plate 16 through an opening. The bottom of the inclined plate 16 is fixedly connected with a connecting plate 17. A first spring 18 is fixedly connected between the top of the connecting plate 17 and the bottom of the support plate 14.

[0025] Furthermore, in order to facilitate the monitoring and recording of overheight vehicles, video monitoring can be adjusted at any time to achieve the traceability function. A camera 19 is fixedly installed on the top of the left fixed rod 12. The camera 19 is electrically connected to an external power supply. An installation box 20 is fixedly connected to the upper side of the left fixed rod 12. A memory 21 is provided inside the installation box 20. The video recorded by the camera 19 can be taken out for viewing through the memory 21.

[0026] When in use, the vehicle passes through the two fixed poles 12 between the two warning boards 2, and the driver of the vehicle is prompted with the height limit through the information display screen 22 and the multiple warning lights 23. At the same time, the camera 19 monitors the vehicle and records it through the memory 21. If the height of the vehicle exceeds the limit without the driver realizing it, the vehicle enters between the two warning boards 2. The over-height position of the vehicle will push the reflective tape 6 to move, so that the reflective tape 6 will pull the sliding block 4 to move in the strip groove 3 through the sliding frame 5, and the first magnet block 8 on the sliding block 4 will separate from the second magnet block 9. At the same time, the squeezing block 7 on the sliding block 4 will no longer squeeze the sliding plate 24. Through the force of the second spring 25, the sliding plate 24 is pushed to press the control button 10, and the two control buttons 10 will immediately control the alarm 11 to sound an alarm, and the driver of the vehicle is warned of over-height through the alarm 11.

[0027] If the vehicle continues to drive after passing the warning of the alarm 11 due to its excessive height, the excessive height of the vehicle will collide with the height limiting plate 13, and the height limiting plate 13 will move due to the impact of the vehicle. The movement of the height limiting plate 13 will squeeze the two inclined plates 16. The inclined surfaces of the inclined plates 16 are squeezed by the height limiting plates 13, so that the inclined plates 16 move downward into the supporting plates 14. The two inclined plates 16 no longer block the height limiting plate 13, and the height limiting plate 13 will be disassembled from the supporting plates 14 by impact, thereby reducing the impact force of the collision with the vehicle.
