Urban roads (including bridges), urban rail transit, water supply, drainage, gas, heat, landscaping, environmental sanitation, road lighting, industrial waste, medical waste, domestic waste treatment equipment, sites and other facilities. Common urban motor vehicle lanes, non-motor vehicle lanes, sidewalks, public parking lots, squares, pipeline corridors and safety passages, shoulders, guardrails, street signs, etc. are all municipal facilities.

[0003] Guardrails are an important device in municipal facilities. They can effectively prevent vehicles from crossing the road due to driver errors or other reasons, and can also prevent traffic accidents from crossing the central divider and entering the opposite lane. They can effectively prevent pedestrians from climbing over the guardrails and reduce the occurrence of traffic accidents. At the same time, municipal highway guardrails can beautify the city to a certain extent. Although it cannot be said that highway guardrails can completely prevent traffic accidents, they can reduce the frequency of traffic accidents after installation.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The existing guardrail fixing device is usually an integrated structure, which makes it inconvenient to adjust the height of the guardrail according to needs, so that the use of the guardrail is limited; 2. The existing guardrail is fixed by bolts, which need to be fixed manually. However, when the bolts are fixed, due to human misoperation or machine vibration, the bolt fixing position is offset, causing the guardrail installation position to be offset, affecting the use of the guardrail. Utility Model Content

[0008] Further preferably, four cylindrical sliders are installed on the outer wall of the adjusting rod, and the inner wall of the supporting base is provided with a cylindrical slide groove whose internal dimension structure is consistent with the external dimension structure of the cylindrical slider, and the adjusting rod and the supporting base constitute a sliding mechanism.

[0009] Further preferably, the insertion rod forms an elastic mechanism through the annular block and the circular baffle and the spring, and the surface of the support base is provided with a plurality of circular holes whose internal dimension structure is consistent with the external dimension structure of the insertion rod.

[0010] Further preferably, the surface of the support base is provided with twelve plug-in blocks in total, and the inner wall of the protective bottom cover is provided with slots whose internal dimension structure is consistent with the external dimension structure of the plug-in blocks, and the protective bottom cover and the support base form a plug-in structure.

[0011] Further preferably, there are four drain outlets in total, and the drain outlets are symmetrical about the central axis of the supporting base, and the bottom surface of the protective bottom cover is provided with a groove whose internal dimension structure is consistent with the internal dimension structure of the drain outlet.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model adopts an adjustable design, which is convenient for the user to align the cylindrical slider of the adjusting rod with the cylindrical slide groove on the inner wall of the supporting base, first press and contract the insertion rod, and then insert the adjusting rod into the supporting base. When the adjusting rod slides inside the supporting base, the insertion rod and the circular baffle plate contract, and the spring is in a compressed state. When the insertion rod is consistent with the circular hole on the surface of the supporting base, the spring recovers, driving the circular baffle plate and the spring to extend. At this time, the insertion rod is inserted into the circular hole to fix the adjusting rod and the supporting base. The surface of the supporting base is provided with a plurality of circular holes, which is convenient for the user to adjust the height of the device according to needs.

[0014] In the utility model, a suction cup design is adopted. First, epoxy resin is brushed on the uneven ground to fill it to make the ground where the device is installed flat. Then, the support base is placed in a suitable position. Then, the air outlet is opened, and the suction cup is vacuumed and then the air outlet is closed. At this time, the suction cup is tightly adsorbed on the ground, and the support base is fixed to the ground, which can effectively avoid the deviation of the device due to machine vibration or human error when installing bolts.
