Description

Technical Field

[0001] The utility model relates to an anti-collision guardrail with adjustable length, belonging to the technical field of guardrails. Background Art

[0002] Guardrails, from the earliest wooden fences, are obstacles set up by people to keep various livestock. Today, guardrails often appear in different forms in our lives, and have a very wide range of uses and connotations. Guardrails are also called fences, which can be divided into industrial fences (such as factory fences, commercial site fences), agricultural fences (such as field fences, livestock fences), civil fences (such as building top fences, fence walls, etc.), public facility fences (such as road isolation fences), etc. According to the materials used, they can be divided into aluminum alloy fences, zinc steel fences, barbed wire fences, electric fences, wooden stake fences, biological fences, wire mesh fences, ditch fences, earth wall fences, stone wall fences, willow fences, PVC fences, cement fences, etc. Aluminum alloy fences and zinc steel fences are common in life and are the most widely used. According to the requirements of use, they are divided into fixed fences and movable fences. The rise of decorative greening fences of various materials is also constantly entering enterprises and various commercial venues and families.

[0003] In the prior art CN201821419498.5, an anti-collision guardrail is disclosed, which relates to the field of guardrail technology, in order to alleviate the technical problems existing in the prior art that the assembly process is cumbersome and the cost is high. The anti-collision guardrail includes a column, a first railing and a second railing; a first mounting hole and a second mounting hole are provided on the column, and the extension direction of the first mounting hole intersects with the extension direction of the second mounting hole; the two columns are arranged on the ground at intervals; the two ends of the first railing extend into the first mounting holes of the two columns respectively; one end of the second railing extends into the second mounting hole of the column and is clamped with the end of the first railing, and the other end is installed on the wall. The anti-collision guardrail does not require welding by a welding machine or tapping by a tapping machine during assembly. The assembly is achieved by splicing between the column, the first railing and the second railing. The assembly process is simple, fast and low in cost.

[0004] However, the device still has disadvantages when it is working. When the device is working, it is assembled by splicing the columns, the first railing and the second railing. The assembly process is simple, fast and low-cost. It is not difficult to see from the above assembly method of the device that the device is more convenient to assemble, but after the assembly is completed, the structure is fixed. If the user needs to adjust the fence structure or open a gap in the fence, the user can only disassemble the fence and reassemble it, which is time-consuming and labor-intensive, and there is nowhere to put the fence components with the gap removed.

[0005] In view of this, there is an urgent need for a length-adjustable anti-collision guardrail to solve the above problems. Utility Model Content
