Description

Technical Field

[0001] The present invention relates to the technical field of guardrails, and more specifically, to an overall assembly design structure of an environmentally friendly guardrail. Background Art

[0002] Metal guardrails are upgraded products of other types of guardrails, such as wooden and stone guardrails. There are many metal materials nowadays. The more commonly used metal guardrails on the market are iron, aluminum, stainless steel, zinc steel and so on.

[0003] However, in the prior art, the internal connections of most metal guardrails are fixed, which makes it inconvenient to disassemble and takes up a lot of space. In addition, although some metal guardrails are easy to install and disassemble, they do not have the function of adjusting the height of the guardrail, which greatly limits the use of the guardrail.

[0004] In view of this, research and improvement are carried out on the existing problems, and an environmentally friendly guardrail overall assembly design structure is provided, aiming to achieve the purpose of solving the problem and improving the value through this technology. Summary of the invention

[0005] The purpose of the present invention is to provide an environmentally friendly guardrail integral assembly design structure to solve the problems and shortcomings raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides an environmentally friendly guardrail overall assembly design structure, which is achieved by the following specific technical means:

[0007] The cam is provided with a plurality of bolts, each of which ...

[0008] As a further optimization of the technical solution, the present invention provides an environmentally friendly guardrail overall assembly design structure, wherein the fourth through holes are in several groups, and the fourth through holes are evenly distributed inside the cross bar. The length of the vertical bar is greater than the sum of the lengths of the fixed support bar and the sliding support bar. By setting the length relationship between the vertical bar and the fixed support bar and the sliding support bar, when the height of the entire metal guardrail needs to be raised or lowered, it can be ensured that the vertical bar is still inside the fourth through hole, thereby achieving the limit work of the vertical bar.

[0009] As a further optimization of the technical solution, the present invention provides an environmentally friendly guardrail overall assembly design structure, the connecting column is U-shaped, the length of the fixing block is larger than the diameter of the second through hole, the number of groups of the second through holes is equal to the number of groups of the fourth through holes, the number of groups of the vertical rods is equal to the number of groups of the fourth through holes, and through the setting of the fixing block and the second through holes, the vertical rods can be supported and fixed, thereby realizing the true function of the guardrail.

[0010] As a further optimization of the technical solution, the present invention provides an environmentally friendly guardrail overall assembly design structure, wherein there are two groups of sliding support rods, and the sliding support rods are symmetrically distributed according to the horizontal center line of the cross bar. The internal diameter of the sliding support rod is larger than the internal diameter of the fixed support rod. By arranging the sliding support rods and the fixed support rods, the height of the guardrail can be adjusted at will, thereby improving the practicability of the metal guardrail.

[0011] As a further optimization of the technical solution, the present invention provides an environmentally friendly guardrail overall assembly design structure, wherein the top end of the vertical rod is located inside the second through hole, and the bottom end of the vertical rod is located inside the fourth through hole. The outer periphery of the vertical rod is only in contact with the inner walls of the second through hole and the fourth through hole but not connected. Through the connection method between the vertical rod and the second and fourth through holes, it is convenient to change the height of the entire device, and at the same time, it is convenient to install and disassemble the vertical rod.

[0012] As a further optimization of the technical solution, the present invention provides an environmentally friendly guardrail overall assembly design structure, wherein there are three groups of the first through holes, and the first through holes are evenly distributed inside the fixed support rod. The size of the first through holes is the same as the size of the third through holes. By setting the first through holes, the height of the guardrail can be adjusted accordingly.

[0013] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0014] 1. The present invention sets the length relationship between the vertical rod and the fixed support rod and the sliding support rod, so that when the height of the entire metal guardrail needs to be raised or lowered, it can ensure that the vertical rod is still inside the fourth through hole, thereby achieving the position limiting work of the vertical rod.

[0015] 2. The present invention facilitates height adjustment of the guardrail and enables better installation and disassembly of the entire device through the provision of bolts and the first and third through holes.

[0016] 3. The present invention facilitates the positioning and fixing of the vertical rod by providing the fixing block and the second through hole, and has the advantage of being more convenient for installing and removing the vertical rod, thereby effectively solving the problems and shortcomings of the existing device.
