The main structure includes the construction of walls, floor slabs, beams and columns. Common construction methods include masonry, pouring concrete, steel structures, etc. During the construction of a house, a construction guardrail is required to surround the outside of the construction site or other construction site to protect the safety of workers and passers-by;

[0003] However, the existing construction guardrails have the following disadvantages: most construction guardrails use a whole protective panel for protection, but the whole protective panel is large in area, which makes it inconvenient for construction workers to carry the guardrail to other construction sites, reducing the convenience of the construction guardrail. Therefore, the current construction guardrails need to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a construction guardrail that is easy to fold and carry, so as to solve the problem raised by the above-mentioned background technology that the entire protective panel of the construction guardrail currently on the market is large in area, which makes it inconvenient for construction workers to carry the guardrail and place it on other construction sites, reducing the convenience of the construction guardrail.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-7The utility model provides a technical solution: a construction guardrail that is easy to fold and carry, comprising a No. 1 column 1 and a No. 2 column 2, a No. 1 guard plate 3 is fixed on one side of the No. 1 column 1, a No. 2 guard plate 4 is arranged on the side of the No. 1 guard plate 3 away from the No. 1 column 1, the No. 2 column 2 is fixed to the side of the No. 2 guard plate 4 away from the No. 1 guard plate 3, a connecting column 6 is movably sleeved on the side of the No. 1 guard plate 3 close to the No. 2 guard plate 4 through a rotating shaft 10, a hinge 7 is connected between the connecting column 6 and the No. 2 guard plate 4, a handle 5 is fixed on the side of the No. 1 column 1 and the No. 2 column 2 away from each other, a No. 2 docking ring 12 is fixed on the side of the No. 1 column 1 away from the No. 1 guard plate 3, a No. 1 docking ring 11 is fixed on the side of the No. 2 column 2 away from the No. 2 guard plate 4, a docking mechanism 13 is installed above the No. 1 docking ring 11, a limiting mechanism 8 is arranged on the inner side of the No. 1 guard plate 3, and connecting mechanisms 9 are installed at both ends of the No. 2 guard plate 4.

[0026] according to Figure 1 , Figure 4 , Figure 6-7 As shown, the limiting mechanism 8 includes a connecting rod 801, a limiting plate 802 and a limiting spring 803. The connecting rod 801 is slidably sleeved in the built-in groove of the No. 1 protective plate 3. The outer side of the connecting rod 801 is sleeved with a limiting spring 803. One end of the connecting rod 801 is fixed with a limiting plate 802. The connecting mechanism 9 includes a hook 901 and a movable shaft 902. The movable shaft 902 is installed at both ends of the No. 2 protective plate 4. The outer side of the movable shaft 902 is movably sleeved with a hook 901, and a protrusion is fixed on the inner side of the limiting plate 802.

[0027] In specific implementation, most construction guardrails will use a whole guard panel for protection, but the guardrail is large in size. When the guardrail needs to be carried and placed in other construction sites, the second guard plate 4 is first folded through the hinge 7, and the connecting column 6 is pulled to rotate around the rotating shaft 10 to fold the second guard plate 4 to one side of the first guard plate 3, and then the limit plate 802 is pulled to one side, so that the limit plate 802 pulls the connecting rod 801 to one side and squeezes the limit spring 803, and then the movable shaft is used to rotate the connecting rod 801 to the other side. 902 rotates hook 901 to make hook 901 hang on connecting rod 801, and then releases limit plate 802, so that limit spring 803 rebounds and drives connecting rod 801 to pull limit plate 802 to one side, and limit plate 802 abuts on hook 901, and at the same time, the protrusion on limit plate 802 abuts on the outside of hook 901, restricting the position of hook 901, so that the guardrail can be quickly folded, and finally the guardrail can be carried by handle 5, which improves the convenience of construction guardrail.

[0028] according to Figure 1-3 and Figure 5As shown, the docking mechanism 13 includes a slide groove 131, a return spring 132, a pull rod 133, a limit block 134 and a docking groove 135. The limit block 134 is provided above the No. 1 docking ring 11, and the docking groove 135 is provided at one end of the No. 1 docking ring 11 close to the limit block 134. The slide groove 131 is provided on the inner side of the No. 1 docking ring 11 close to the limit block 134. The return spring 132 is provided inside the slide groove 131. The limit block 134 is provided on the inner side of the No. 1 docking ring 11 close to the limit block 134. 134 is located at one end of the return spring 132, and one end of the limit block 134 is slidably connected to the slide groove 131. The side of the limit block 134 away from the slide groove 131 is connected to a pull rod 133, and one end of the pull rod 133 is located on the outside of the slide groove 131. The cross-sectional shape of the slide groove 131 is arc-shaped. There is a snap-fit ​​structure between the limit block 134 and the docking groove 135. The number of the No. 1 docking ring 11 and the No. 2 docking ring 12 are both provided with two.

[0029] During specific implementation, since multiple construction guardrails are needed when the guardrail surrounds the outside of the construction site, and the multiple construction guardrails need to be connected, the No. 2 docking ring 12 of the guardrail can be aligned with the No. 1 docking ring 11 of another guardrail, and then the pull rod 133 is pulled to one side, so that the pull rod 133 drives the limit block 134 to slide to one side in the slide groove 131 and squeeze the reset spring 132, and then the No. 2 docking ring 12 is inserted into the No. 1 docking ring 11 from top to bottom, and finally the pull rod 133 is released, so that the reset spring 132 rebounds and pushes the limit block 134 to slide outward in the slide groove 131, and one end of the limit block 134 is engaged with the docking groove 135, so that the guardrail can be quickly docked with another guardrail, thereby improving the practicality of the guardrail.

[0030] Working principle: When using this kind of construction guardrail that is easy to fold and carry, first, install the No. 1 column 1 and the No. 2 column 2 to the periphery of the construction site, and then connect the guardrail to another guardrail through the No. 1 docking ring 11 and the No. 2 docking ring 12 and the docking mechanism 13, so that the construction guardrail surrounds the outside of the construction site to warn pedestrians and vehicles around. When the construction guardrail needs to be carried and moved to other construction sites, the No. 1 guard plate 3 and the No. 2 guard plate 4 can be quickly folded through the limiting mechanism 8 and the connecting mechanism 9, and then the construction guardrail can be carried by the handle 5, which improves the convenience and practicality of the construction guardrail. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
