Description

Technical Field

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

[0002] There are many types of guardrails, which can be directly installed on the ground by pouring or placed directly on the ground. Guardrails installed by pouring are generally long-term guardrails. In order to prevent pedestrians from climbing, some steel fork-like structures with potential safety hazards are welded on the upper end of the guardrail. The main purpose of this structure is to intimidate and give people a sense of danger, thereby reducing the occurrence of climbing incidents, but it cannot completely eliminate climbing. Once someone climbs, this steel fork structure will be extremely dangerous and may cause direct harm to the climber.

[0003] For example, Chinese patent publication number CN208718495U discloses a safety guardrail, comprising a first column, an upper railing rotatably connected to the upper surface of the first column, an anti-flip thorn fixedly installed on the upper surface of the upper railing, a second column rotatably installed on the lower surface of the upper railing, a telescopic frame fixedly installed on the side of the first column, a lower railing rotatably connected to the side of the first column near the telescopic frame, and a mounting base fixedly installed on the lower surfaces of the first column and the second column; the guardrail can be shrunk together through the telescopic frame, the upper railing and the lower railing, and its volume is greatly reduced for easy transportation; and the guardrail is an integrated structure.

[0004] However, in the above solution, once someone climbs the guardrail, the anti-flip thorn structure will be extremely dangerous and may cause direct harm to the climber, and the safety is low. Utility Model Content

[0008] As a further improvement of the present technical solution: multiple protective structures include multiple sliding grooves, and multiple sliding grooves are respectively opened on the top side walls of each mounting rod, each sliding groove is fixedly connected to a second spring at the bottom, each second spring is fixedly connected to a sliding plate at the top, each sliding plate is slidably connected in the corresponding sliding groove, each sliding plate is fixedly connected to a connecting rod at the top, each connecting rod extends a corresponding sliding groove from the top and is fixedly connected to a first spring, each first spring is fixedly connected to the bottom side wall of the corresponding conical rod, and each mounting rod has a through groove opened on both side walls.

[0009] As a further improvement of the technical solution: each of the first springs and each of the second springs are made of stainless steel.

[0010] As a further improvement of the technical solution: a rubber protective sleeve is provided on the side wall of each of the first spring outer rings, and the top and bottom of each of the rubber protective sleeves are fixedly connected to the side walls of the corresponding cone rod and the connecting rod.

[0011] As a further improvement of the technical solution: transverse thorn rods are fixedly connected to both side walls of the top of each cone rod.

[0012] As a further improvement of the technical solution: triangular reinforcement plates are fixedly connected to both side walls of the two support rods, and the bottoms of the four triangular reinforcement plates are fixedly connected to the top side walls of the corresponding base plate.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the device can protect people when people forcibly climb the guardrail through the mutual coordination of the guardrail, the base plate, the mounting rod, the sliding plate and other components, thereby preventing people from being stabbed by the cones, improving the safety of people's climbing, and having high safety.
