Snap-on composite guardrail

Abstract

The invention discloses a snap-on composite guardrail, including a base, the upper side of the base is provided with upright columns, two sets of symmetrically distributed through holes are arranged on both sides of the middle position of the upright column, a connecting rod is arranged at the inner middle position of the through hole, one end of the connecting rod is connected with the upright post through a hexagon bolt, the other end of the connecting rod is connected with one side of the retaining ring, one side of the other set of first transverse guard rails is provided with two or moresets of arc-shaped skateboards which are equally spaced apart, one end of the vertical guardrail is connected to one side of the arc-shaped slide plate close to the clamping hole, the other end of thevertical guardrail is connected with the first transverse guardrail through a clamping hole, through the design of the clamping hole, the positioning hole and the positioning column, the whole guardrail does not need to be welded, the process is simple and the cost is low, the cost can be reduced, the number of holes punched on the railing body is reduced through the design of the arc-shaped slide plate, the public notice board and the pasting groove can be popularized in commercial advertisement, and the economic benefit can be increased.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a clamping composite guardrail. Background technique [0002] Generally, there are two ways to connect the vertical bars of the guardrail and the upper and lower horizontal bars. One is to weld the guardrail as a whole, and the other is to insert plug-in components. The welding method cannot be recycled, and the welding In the process, it is easy to deviate from the appearance of the product and other phenomena. Among them, the plug-in plug-in component needs to open two small through holes at both ends of each vertical rod, so the processing is cumbersome. If the rubber sealing ring is damaged, its connection will be affected. For example, the patent application publication number CN 202108017 U discloses a clip-on composite guardrail, the length of the clip body is less than the length of the special-shaped hole and larger than the length of the special-shaped hole The uppe...

[0002] Generally, there are two ways to connect the vertical bars of the guardrail and the upper and lower horizontal bars. One is to weld the guardrail as a whole, and the other is to insert plug-in components. The welding method cannot be recycled, and the welding In the process, it is easy to deviate from the appearance of the product and other phenomena. Among them, the plug-in plug-in component needs to open two small through holes at both ends of each vertical rod, so the processing is cumbersome. If the rubber sealing ring is damaged, its connection will be affected. For example, the patent application publication number CN 202108017 U discloses a clip-on composite guardrail, the length of the clip body is less than the length of the special-shaped hole and larger than the length of the special-shaped hole The upper surface of the lower cross bar is provided with a square hole, and the protrusion includes a convex body and a welding body positioned above the convex body; the length of the convex body is less than the length of the square hole, and the width of the convex body Smaller than the width of the square hole, but the above patents require internal welding during use, the process is complex and costly, and cannot meet the cost requirements, and the position of the connection is prone to deviation
