Description

Technical Field

[0001] The utility model relates to the field of highway facilities, in particular to a highway speed reduction belt. Background Art

[0002] Highway speed bumps are traffic facilities installed on the road to slow down passing vehicles. They are usually strip-shaped or dot-shaped; they are mainly made of rubber, but also metal; they are usually yellow and black to attract visual attention, and slightly bulge the road surface to achieve the purpose of slowing down vehicles.

[0003] Most of the existing highway speed bumps only have the effect of decelerating, and it is not easy to further limit the speed of the oncoming vehicle, which may lead to insufficient safety of the device. It is not easy to adjust and install the appropriate number of existing highway speed bumps, which may lead to reduced adaptability of the device.

[0004] Therefore, a highway speed bump is proposed in response to the above problems. Utility Model Content

[0007] Preferably, bolts are threadedly engaged at positions near the four corners of the surface of the mounting plate, and the mounting plate is fixedly connected between two adjacent shells by the bolts.

[0008] Preferably, the inner wall of the shell is fixedly connected with a base, arc plates are rotatably connected to both sides of the base, the bottom of the arc plates is fixedly connected with a mounting block, and the size of the arc plates matches the size of the through slots.

[0010] Preferably, a spring is slidably sleeved on the surface of the sliding column, and one end of the sliding column is pressed against one end of the connecting rod.

[0011] Preferably, oblique blocks are fixedly connected to both sides of the shell, and rivets are provided through the surface of the oblique blocks.

[0012] The utility model is beneficial in that:

[0013] 1. The utility model presses down the arc plate to slide the sliding column backward through the connecting rod, and realizes the function of a normal speed bump when a vehicle traveling in the forward direction rolls over the inclined block and the shell through the structural design of spring energy storage. The device is easy to reset and easy to use later. When encountering a reverse vehicle, the arc plate is not easy to fall due to the large angle of the arc plate, which has a greater obstruction to the vehicle, effectively reducing the speed of the reverse vehicle and improving the safety of the device.

[0014] 2. The utility model improves the stability of the device after installation by means of a structural design in which a mounting plate is mounted in a groove and two adjacent shells are fixedly connected by bolts, thereby facilitating the expansion and installation of a suitable number of devices and improving the adaptability of the device.

[0023] Furthermore, bolts 9 are threadedly matched at the four corners of the surface of the mounting plate 8, and the mounting plate 8 is fixedly connected between two adjacent housings 2 by the bolts 9;

[0024] During operation, the mounting plate 8 is designed to fix two adjacent housings 2 with bolts 9, thereby improving the stability of the device after installation and facilitating the installation of a suitable number of devices.

[0025] Furthermore, the inner wall of the housing 2 is fixedly connected with a base 10, and arc-shaped plates 6 are rotatably connected to both sides of the base 10, and the bottom of the arc-shaped plates 6 is fixedly connected with a mounting block 11, and the size of the arc-shaped plates 6 is consistent with the size of the through slot 5;

[0026] During operation, the structural design that the size of the arc plate 6 matches the size of the through groove 5 improves the sealing performance of the device and reduces the possibility of debris falling into the device and causing blockage.

[0027] Furthermore, the interior of the slide groove 131 is slidably connected to one end of the connecting rod 12, and the other end of the connecting rod 12 is rotatably connected to the side of the mounting block 11;

[0028] During operation, the two ends of the connecting rod 12 slide in the slide groove 131 respectively and rotate to connect the side of the mounting block 11 , so that the sliding column 15 pushes the connecting rod 12 to drive the mounting block 11 to adjust its position.

[0029] Furthermore, a spring 16 is slidably sleeved on the surface of the sliding column 15, and one end of the sliding column 15 is pressed against one end of the connecting rod 12;

[0030] During operation, the spring 16 is slidably sleeved on the surface of the slide post 15 so that one end of the slide post 15 is pressed against one end of the connecting rod 12 , so that the arc plate 6 tends to rotate upward, thereby restoring the arc plate 6 .

[0031] Furthermore, the two sides of the housing 2 are fixedly connected with inclined blocks 3, and the surface of the inclined blocks 3 is penetrated by rivets 4;

[0032] During operation, the two sides of the shell 2 are fixedly connected with the inclined block 3, so that the bottom surface of the inclined block 3 is fixed to the ground. The inclined block 3 and the shell 2 are in a trapezoidal structure, which is convenient for decelerating the vehicle.

[0033] Working principle: by embedding the installation base plate 1 and the shell 2 in the ground, the bottom surface of the inclined block 3 is in contact with the ground, and the side of the curved plate 6 close to the base 10 is facing the direction of the vehicle. When the vehicle traveling in the forward direction rolls over the inclined block 3 and the shell 2, it plays a normal speed bump effect. Since the orientation angle of the curved plate 6 is small, the curved plate 6 is pressed down through the connecting rod 12 to make the sliding column 15 slide backward, and energy is stored through the spring 16. When the vehicle leaves the shell 2, the spring 16 pushes the sliding column 15 to make one end of the connecting rod 12 slide in the slide groove 131, driving the curved plate 6 to rotate upward and reset, which is convenient for subsequent use. When encountering a reverse vehicle, due to the large orientation angle of the curved plate 6, the curved plate 6 is not easy to fall, and the obstruction to the vehicle is large, which effectively reduces the speed of the reverse vehicle. The stability of the device after installation is improved by engaging the mounting plate 8 in the groove 7 and fixing the two adjacent shells 2 with bolts 9.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
