Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a high-strength corrosion-resistant steel guardrail. Background Art

[0002] Guardrail nets are mainly used for the protection and protection of personal safety and equipment facilities in residential areas, highways, commercial areas, public places and other occasions. They are mainly composed of two parts: posts and protective nets, and most of them are fixed with bolts;

[0003] Since guardrail nets are normally used outdoors, in order to extend the service life of the guardrail nets, the surface of existing guardrail nets is normally coated with corrosion-resistant paint. However, since the columns and the protective nets are mostly connected and fixed by bolts, and the existing guardrail nets do not have a corrosion-resistant structure for the bolts, the bolts are exposed to the outside for a long time and are easily eroded by rainwater and rusted, which makes it very inconvenient to dismantle the guardrail net in the later stage, increases the difficulty of disassembly, and brings inconvenience to people's use. Utility Model Content

[0004] The purpose of the present invention is to provide a high-strength corrosion-resistant steel guardrail to solve the above problems.

[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a high-strength corrosion-resistant steel guardrail, comprising;

[0006] Expandable railing structure, which includes upper keel, railing A, lower keel, extension frame, railing B, and insert rod;

[0007] The upper keel frame is located above the lower keel frame. One end of each of the upper and lower keel frames has an integrally fixed plug rod, and the diameter of the plug rod is equal to the diameter of the hollow inside the extension frame. The plug rod on one guardrail is inserted into the extension frame on the other guardrail. When the spring buckle abuts against it, it is squeezed, so that the spring buckle is squeezed and locked inside the plug rod. Continuously pushing the plug rod causes the spring buckle to rebound and embed into the limit grooves on both sides of the extension frame, thereby achieving the purpose of limiting and completing the expansion between the two guardrails.

[0008] The other end of the upper and lower keel frames each has an integrally fixed connecting block A. One end of the extension frame is through-shaped, and the other end of the extension frame has an integrally fixed connecting block B. The connecting block B is hinged to the connecting block A. After installation, the connecting block A and the connecting block B can be rotated downward to adjust the angle, so that the angle between the two guardrails can be adjusted, making it suitable for more scenarios.

[0009] Preferably, there are multiple railings A between the upper dragon frame and the lower dragon frame, and the two ends of the railings A are welded and fixed to the upper dragon frame and the lower dragon frame respectively. There is a spacing between every two railings A, and the outer sides of the upper dragon frame, the lower dragon frame, the railings A and the railings B are sprayed with an anti-corrosion coating to prevent corrosion of each component, thereby increasing the service life of each component.

[0010] Preferably, there is a railing B between the two extension frames, and the two ends of the railing B are respectively welded and fixed to the two extension frames. The structure can be expanded through the extension frames, and the extension frames can be rotated to adjust the angle between the two guardrails, which is suitable for curved roads.

[0011] Preferably, the extension frame is made of metal, and one end of the insertion rod has a fixedly connected magnetic block.

[0012] Preferably, a plurality of limiting grooves are provided on both sides of the extension frame, and one end of the insertion rod has a symmetrical magnetic block, which passes through the corresponding limiting groove and is engaged with the limiting groove.

[0013] Preferably, both sides of the lower keel frame have a plurality of integrally fixed connecting blocks C, and the connecting block C is hingedly connected to a support rod at one end away from the lower keel frame. The support rod can rotate with the connecting block C. After rotation, the support rod and the lower keel frame enlarge the angle, so that the support rod is supported on both sides of the keel frame to prevent tipping, and the support rod fits with the keel frame when stored, with a compact structure and more space-saving.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The insertion rod on one guardrail is inserted into the extension frame on the other guardrail. When the spring hook contacts the extension frame, it is squeezed and locked inside the insertion rod. Continuously pushing the insertion rod causes the spring hook to rebound and embed into the limit slots on both sides of the extension frame, thereby achieving the purpose of limiting the position and completing the extension between the two guardrails. After installation, the connection block A and the connection block B can be rotated downward to adjust the angle, so that the angle between the two guardrails can be adjusted, which is suitable for more scenarios.

[0016] 2. This structure uses embedded clips instead of screws to avoid the corrosion and thread slippage of the screws after long-term use. The structure of this utility model can be expanded to any length to facilitate the installation of guardrails of different lengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Furthermore, there are multiple railings A102 between the upper keel frame 100 and the lower keel frame 103, and the two ends of the railing A102 are welded and fixed to the upper keel frame 100 and the lower keel frame 103 respectively. There is a spacing between every two railings A102, and the outer sides of the upper keel frame 100, the lower keel frame 103, the railing A102 and the railing B202 are sprayed with an anti-corrosion coating to prevent corrosion of each component, thereby improving the service life of each component.

[0029] Furthermore, there is a railing B202 between the two extension frames 200, and the two ends of the railing B202 are welded and fixed to the two extension frames 200 respectively.

[0032] Furthermore, both sides of the lower keel frame 103 have a plurality of integrally fixed connecting blocks C400, and the end of the connecting block C400 away from the lower keel frame 103 is hinged with a support rod 401, and the support rod 401 can rotate with the connecting block C400. After rotation, the support rod 401 and the lower keel frame 103 enlarge the angle, so that the support rod 401 is supported on both sides of the keel frame 103 to prevent tipping, and the support rod 401 fits with the keel frame when stored, with a compact structure and more space saving.

[0033] Working principle: When in use, the insertion rod 300 on one guardrail is inserted into the extension frame 200 on the other guardrail, and the spring buckle 301 is squeezed when it abuts against 00, so that the spring buckle 301 is squeezed and locked inside the insertion rod 300, and the insertion rod 300 is continuously pushed, so that the spring buckle 301 rebounds and embeds into the limiting grooves on both sides of the extension frame 200, thereby achieving the purpose of limiting, and then completing the expansion between the two guardrails. After installation, the connecting block A101 and the connecting block B201 can be rotated downward to adjust the angle, so that the angle between the two guardrails can be adjusted, which is suitable for more scenarios.
