Description

Technical Field

[0001] This utility model relates to the field of signage technology, and in particular to road signage that is easy to assemble and disassemble and is collision-resistant. Background Technology

[0002] Signage, as public facilities, is installed in various public places, including roadside signs. To improve the visibility of the signs, they are often placed at very high positions. Roadside signs are easily hit by vehicles, and when they are hit, they can tip over and injure pedestrians, causing injuries or fatalities. This problem needs to be solved. In addition, signs are often directly scrapped and discarded after being hit, and cannot be repaired or recycled, resulting in resource waste, which is also a problem that needs to be addressed. Therefore, a road sign with easy disassembly and collision protection has been designed. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to propose a road sign that is easily detachable and impact-resistant, achieving gradient energy absorption and buffering. After a collision, damaged parts can be replaced and reset according to the collision situation, ensuring the safety of the sign while maintaining its recognition range.

[0004] The road sign with easy disassembly and collision protection proposed according to this utility model includes a cement pile, a mounting base fixed on the upper surface of the cement pile, an assembly box fixedly fitted on the surface of the mounting base, a top cover fixedly fitted on the top of the assembly box, a top sign plate movably installed inside the assembly box, multiple springs fixed between the top sign plate and the mounting base, a collision protection plate movably installed on the side wall of the assembly box, an energy-absorbing arc plate fixedly fitted between the collision protection plate and the side wall of the assembly box, multiple damping rods fixed on the side wall of the collision protection plate and between the energy-absorbing arc plates, and a synchronization plate fixed to the moving end of the damping rods.

[0005] The side wall of the assembly box has symmetrically opened limit grooves. An installation plate is fixed on the side wall of the assembly box above the limit groove. A support rod is movably installed inside the installation plate. A baffle is fixed at the bottom of the support rod. A top rod is fixed on the side wall of the anti-collision plate at the same height as the limit groove.

[0006] Preferably, multiple limiting tubes are symmetrically fixed to the side wall of the assembly box, and a movable tube is movably installed inside each limiting tube. The end of each movable tube away from the limiting tube is fixed to the anti-collision plate.

[0007] Preferably, a side label plate is fixed to the side wall of the assembly box, and a plurality of fasteners are fixed to the side wall of the side label plate, the fasteners being fitted and fixed inside the limiting tube.

[0008] Preferably, a soft pad is fixed to the outside of the anti-collision plate, a warning plate is provided on the upper side of the side wall of the soft pad, and a foam sign plate is fixed between the warning plate and the side sign plate.

[0009] Preferably, a compression ball is threaded onto the end of the top rod away from the anti-collision plate.

[0010] Preferably, the assembly box is equipped with a groove plate for assembling the energy-absorbing arc plate, which is installed parallel to the opposite side of the anti-collision plate.

[0011] The beneficial effects of this utility model are as follows: by setting up a soft pad, an energy-absorbing arc plate and a damping rod, a gradient energy absorption buffer is achieved. After a collision, the damaged parts can be replaced and reset according to the collision situation. Disassembly and assembly are convenient. When the collision energy exceeds the energy absorption effect, the support for the top sign plate is released in time, and the top sign plate is quickly brought back in by a spring to prevent the sign from falling and hitting pedestrians. The safety of the sign is guaranteed without reducing the recognition range of the sign. Attached Figure Description

[0019] Reference Figure 1-6 The road sign is designed to be easily disassembled and is collision-resistant. It includes a cement post 1, a mounting base 2 fixed on the upper surface of the cement post 1, an assembly box 3 fixed on the surface of the mounting base 2, the height of the assembly box being controlled at about 1.2 meters to reduce the probability of it tipping over and hitting the head of pedestrians, a top cover 4 fixed on the top of the assembly box 3, a top sign plate 5 movably installed inside the assembly box 3, multiple springs 6 fixed between the top sign plate 5 and the mounting base 2, a collision protection plate 7 movably installed on the side wall of the assembly box 3, an energy-absorbing arc plate 8 made of elastic plastic fixed between the collision protection plate 7 and the side wall of the assembly box 3, which can effectively absorb collision energy, multiple damping rods 9 fixed on the side wall of the collision protection plate 7 and between the energy-absorbing arc plates 8, and a synchronization plate 10 fixed to the moving end of the damping rods 9.

[0020] The side wall of the assembly box 3 is symmetrically provided with limiting grooves 31. The baffle 13 can rotate within the limiting grooves 31. The side wall of the assembly box 3 and above the limiting grooves 31 is fixed with an mounting plate 11. The mounting plate 11 is movably installed with a support rod 12. The bottom of the support rod 12 is fixed with a baffle 13. The side wall of the anti-collision plate 7 and at the same height as the limiting grooves 31 are fixed with a top rod 14. The baffle 13 contacts the bottom of the top marking plate 5 to provide support for the top marking plate 5.

[0021] Multiple limiting tubes 32 are symmetrically fixed on the side wall of the assembly box 3. Each limiting tube 32 has a movable tube 72 installed inside it. The end of the movable tube 72 away from the limiting tube 32 is fixed to the anti-collision plate 7.

[0022] The side wall of the assembly box 3 is fixed with a side label plate 15, and the side wall of the side label plate 15 is fixed with multiple fasteners, which are fixed in a set inside the limiting tube 32.

[0023] A soft pad 71 is fixed to the outside of the anti-collision plate 7. A warning plate 16 is provided on the upper side of the side wall of the soft pad 71. A foam sign plate 17 is fixed between the warning plate 16 and the side sign plate 15. The foam sign plate 17 increases the sign area, provides a small energy absorption effect, is easily damaged, and improves the appearance of the sign.

[0024] The end of the top rod 14 away from the anti-collision plate 7 is threaded with a compression ball 141. When there is a violent collision, the compression ball 141 contacts the baffle 13 and pushes the baffle 13 to rotate, pushing the baffle 13 away from the top marking plate 5 and releasing the support of the top marking plate 5.

[0025] The assembly box 3 and the anti-collision plate 7 are parallel to each other and have grooved plates for assembling the energy-absorbing arc plate 8, which facilitates the disassembly and assembly of the energy-absorbing arc plate 8 after a collision.

[0026] When a vehicle collides with this sign, three scenarios are considered based on the collision energy:

[0027] In the first scenario, the vehicle makes slight contact with this sign. The collision energy absorption process is as follows: the soft pad 71 is deformed under pressure, the anti-collision plate 7 moves slightly, the energy-absorbing arc plate 8 absorbs energy and deforms slightly, and the energy-absorbing arc plate 8 automatically returns to its original state after the vehicle is moved away.

[0028] In the second scenario, the collision between the vehicle and this sign is quite severe. The energy absorption process is as follows: the soft pad 71 is deformed under pressure, the anti-collision plate 7 moves a certain distance and comes into contact with the synchronous plate 10, the moving end of the damping rod 9 moves and contracts to absorb the collision energy, and the energy-absorbing arc plate 8 absorbs the energy and deforms significantly, resulting in irreversible deformation.

[0029] In the third scenario, a violent collision occurs between the vehicle and the sign. The energy absorption process is as follows: the soft pad 71 is deformed under pressure, the anti-collision plate 7 moves to its limit position, the moving end of the damping rod 9 fully retracts, the energy-absorbing arc plate 8 absorbs a large amount of energy and breaks, at which point the top rod 14 squeezes the baffle 13 and causes the baffle 13 to rotate, causing the baffle 13 to separate from the top sign plate 5. The top sign plate 5 is pulled down rapidly by gravity and the spring 6, and the top sign plate 5 is housed in the assembly box 3 to prevent the sign from hitting the head of pedestrians when it tilts.

[0030] In the first case, no parts of the sign need to be replaced. In the second case, only the energy-absorbing arc plate 8 needs to be replaced, and the anti-collision plate 7 and damping rod 9 need to be reset. In the third case, if the sign is overturned due to excessive impact energy, it is necessary to dig a new pit, pour cement pile 1, and reassemble the sign. If only the top sign plate 5 is activated and the structure of the sign is not damaged except for the energy-absorbing arc plate 8, the energy-absorbing arc plate 8 can be replaced and the parts reset.
