Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a guardrail used at a bend on an expressway. Background Art

[0002] Guardrails are usually installed at bends on highways to prevent vehicles from accidentally running off the road and causing serious damage. Guardrails are a continuous structure made of corrugated guardrail panels spliced ​​together and supported by columns. They absorb energy when vehicles collide with them, making them not easily destroyed and at the same time providing good protection for vehicles and drivers and passengers.

[0003] The prior art has the following deficiencies: the prior art publication number 202020271039.8 states that “a highway guardrail” includes “a plurality of vertical pole structures, both sides of the plurality of vertical pole structures are provided with mounting grooves, between two adjacent vertical pole structures, the two mounting grooves are detachably connected to a first partition plate, and in the horizontal direction, two adjacent first partition plates are detachably connected to a first reinforcing plate”;

[0004] When the above-mentioned equipment is used in foggy and hazy weather, due to the dim light at the guardrail, the driver often cannot find the guardrail in time, which may cause the vehicle to accidentally hit the guardrail, causing unnecessary losses. In addition, the existing guardrails used at highway bends are usually buffered by the corrugated structure of the guardrail plate itself. The buffering effect is limited if it is only buffered by the corrugated structure of the guardrail plate itself. The buffering effect of the guardrails used at highway bends can be further improved.

This structure can facilitate the driver to find the guardrail in time in foggy weather.

[0016] 2. This type of guardrail is used for bends in highways. By setting a buffer mechanism, the first mounting pad and the second mounting pad can facilitate the installation of the first buffer block and the second buffer block. Since the first buffer block and the second buffer block themselves have a certain buffer effect and one end of each group of first buffer blocks is always in contact with one end of the corresponding second buffer block, the first buffer block and the second buffer block can offset the impact force received by each other, thereby further improving the buffering effect of the guardrail itself. This structure can further enhance the buffering effect of the guardrail used for bends in highways. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The working principle and use process of the utility model: the operator first checks whether the relevant components are installed in the correct position. Since the opening size of the adjusting groove 9 is larger than the lighting component 7, the opening size of the silicone ring 10 is adapted to the lighting component 7. One end of the lighting component 7 can be tilted through the silicone ring 10 in the first fixing block 5 and then inserted into the adjusting groove 9. While squeezing the adjusting block 11, the lighting component 7 is straightened (the corresponding installation spring 12 will be squeezed in this process). At this time, the other end of the lighting component 7 is aligned with the installation groove 13, and the other end of the lighting component 7 is inserted into the installation groove 13 after passing through the silicone ring 10 in the second fixing block 6. In this process, the silicone ring 10 will be squeezed and deformed and will be close to the lighting component 7. Due to the rebound effect of the installation spring 12, the two ends of the lighting component 7 will be close to the bottom of the installation groove 13 and the adjusting block 11 respectively, and the lighting component 7 will not detach from the first fixing block 5 and the second fixing block 6 at will, so the installation of the lighting component 7 can be completed. Since the lighting component 7 is located on the inner side of the column and higher than the guardrail plate 1, the lighting component 7 is not easy to The light will not be blocked by the guardrail plate 1 when hit, and the lighting component 7 can play a lighting warning effect in foggy weather, which can facilitate the driver to find the guardrail in time. The transparent plastic plate 15 can seal the empty slot 14 without affecting the lighting effect of the electronic light strip inside the empty slot 14. When the lighting component 7 needs to be disassembled later, the above operation is performed in reverse. The disassembly and assembly of the lighting component 7 is relatively convenient. The first mounting pad 802 and the second mounting pad 803 can facilitate the installation of the first buffer block 804 and the second buffer block 805. Since the first buffer block 804 and the second buffer block 805 themselves have a certain buffering effect and one end of each group of first buffer blocks 804 is always attached to one end of the corresponding second buffer block 805, the first buffer block 804 and the second buffer block 805 can offset the impact force received by each other, thereby further improving the buffering effect of the guardrail plate 1 itself. This structure can facilitate the driver to find the guardrail in time in foggy weather, and can further improve the buffering effect of the guardrail at the bend of the highway.
