Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrails, in particular to a highway guardrail with adjustable height. Background Art

[0002] In modern life, road safety has attracted much attention, especially on highways, where vehicles travel at high speeds, and the probability of traffic accidents is greatly increased. Therefore, guardrails are installed on highways to block and reduce the losses caused by collisions, and to prevent further traffic accidents through railings. However, the existing guardrails have many defects in installation and use that need to be improved.

[0003] The current highway guardrails are of uniform height and cannot be adjusted, which makes it very likely for pedestrians to climb over them, which can easily cause harm. In addition, the highway guardrails are very troublesome to carry because they are too heavy at the bottom, which increases the workload of the staff. At the same time, the crossbars of the highway guardrails are inconvenient to install, which increases the difficulty of installation for operators.

[0004] In view of the above problems, the inventor proposes a highway guardrail with adjustable height to solve the above problems. Utility Model Content

[0005] In order to solve the problems in the background technology, the purpose of the utility model is to provide a highway guardrail with adjustable height.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a highway guardrail with adjustable height, comprising a column and a movable column, the movable column being inserted on the column, a base being installed at the bottom of the column, two symmetrically distributed U-shaped mounting blocks being fixedly provided on the side wall of the movable column, a mounting groove being formed between the two mounting blocks, a railing being movably provided in the mounting groove, a mounting hole being provided on the side wall of the railing near one end of the movable column, two symmetrically distributed fixing plates being fixedly provided on the outer wall of the railing near one end of the movable column, an insertion rod being inserted on the fixing plate, and a fixing hole corresponding to the insertion rod being provided on the side wall of the movable column near the railing.

[0007] Preferably, a fixing block corresponding to the mounting hole on the railing is fixedly provided on the mounting block, and a mounting rod is inserted into the fixing block.

[0008] Preferably, a water injection hole is provided on the side wall of the base, a drainage hole is provided in the middle of the larger surface of the base, a plug cover is inserted on the drainage hole, and a friction block is provided on the side wall of the base close to the larger surface.

[0010] Preferably, the support block is provided with a second conical tooth, the second conical tooth is fixedly connected to the screw rod, a driving hole is opened on one side of the movable column, a driving rod is inserted into the driving hole, a first conical tooth is fixedly provided on one end of the driving rod close to the second conical tooth, the first conical tooth is meshed with the second conical tooth, a connecting rod is fixedly provided on one end of the driving rod away from the first conical tooth, and a handle is fixedly inserted on one end of the connecting rod away from the driving rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Water can be injected into the base by setting a water injection hole, so that the overall gravity of the base is increased. The friction between the base and the ground is increased with the existence of the friction block, which improves its stability. When placed and tipped, at the same time, during subsequent transportation, since water is injected, the water is subsequently discharged through the drainage hole, which can greatly reduce the gravity of the base, thereby facilitating the transportation of the base;

[0013] 2. The rotation of the screw will cause the support block to move, thereby driving the height of the movable column to change, thereby increasing the vertical height of the highway guardrail, thereby reducing the possibility of pedestrians climbing over;

[0014] 3. The end of the railing can be initially limited by the mounting block and the mounting groove. At the same time, the mounting rod is inserted into the fixing block to ensure that it will not move easily. At this time, the fixing plate and the fixing hole will be stably aligned, which will facilitate subsequent staff to directly fix and install with bolts, thereby improving the stability and portability of the installation.

[0037] Then, the column 2 is installed on the base 3, and the handle 13 is turned to drive the connecting rod 12 to rotate the driving rod 11. The movement of the driving rod 11 drives the first conical tooth 14 to mesh with the second conical tooth 151, thereby driving the screw 16 to rotate. The rotation of the screw 16 causes the support block 15 to move, thereby driving the height of the movable column 1 to change, thereby increasing the vertical height of the highway guardrail, thereby reducing the possibility of pedestrians climbing over;

[0038] The operator can insert the railing 48 into the mounting groove 49, the fixing block 43 will correspond to the mounting hole 47, and insert the mounting rod 41, and finally insert the insertion rod 46 into the fixing hole 17, and the mounting rod 41 is inserted into the fixing block 43 to ensure that it will not move easily, thereby fixing the railing 48 and improving stability and portability.
