[0024] Example 1

[0025] like Figure 1-5 As shown, the utility model provides a construction guardrail that is easy to fold and store, including a guardrail body 1, which is suitable for use in protection of construction sites. The guardrail body 1 includes a support column 2, a support column 2 3 is provided on the right side of the support column 2, a counterweight base 4 is fixedly installed on the bottom ends of the support column 2 and the support column 2 3, a storage unit is provided between the support column 1 2 and the support column 2 3, and a positioning unit is provided on the top between the support column 1 2 and the support column 2 3. The positioning unit includes a positioning unit opened on the top of the support column 2 Through hole 25, a fixing rod 26 is fixedly installed on the inner top of support column 2 3, and a connecting cross bar 27 is rotatably installed on the other end of the fixing rod 26. An external thread 28 is provided on the outer surface of the other end of the connecting cross bar 27. The other end of the connecting cross bar 27 passes through the through hole 25 and extends on the left outer surface of support column 1 2. The other end of the connecting cross bar 27 is located on the outer surface of the external thread 28 and a fixing ring 1 29 is threadedly sleeved. On the left side of the fixing ring 1 29, a fixing ring 2 210 is threadedly sleeved on the outer surface of the external thread 28.

[0026] Furthermore, by pulling the support column 2 3 so that it gradually moves away from the support column 1 2, the folding plate 22 itself can adjust its horizontal length as needed. After adjustment, the fixing ring 1 29 and the fixing ring 2 210 on both sides of the top of the rotating support column 1 2 are coordinated to rotate on the outer surface of the external thread 28 and fit tightly on both sides of the support column 1 2. The fixing rod 26 and the connecting cross bar 27 are used to fix the guardrail after the length is adjusted.

[0027] Example 2

[0028] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the storage unit includes a movable groove 21 on both sides of the support column 1 2 and the support column 2 3, and a storage folding plate 22 is arranged between the support column 1 2 and the support column 2 3, and a sliding rod 23 is fixedly installed at both ends of the storage folding plate 22, and the sliding rod 23 is slidably installed inside the movable groove 21, and a limiting disk 24 is fixedly installed on the other end of the sliding rod 23, a splint 211 is fixedly installed on the left end of the fixed rod 26, and a rotating plate 212 is fixedly installed on the right end of the connecting cross bar 27, and a bearing rod 213 is rotatably sleeved inside the rotating plate 212, and both ends of the bearing rod 213 are fixedly installed inside the splint 211.

[0029] Furthermore, when not in use, the fixing ring 1 29 is rotated to disengage the external thread 28 and pull it onto the outer surface of the fixing rod 26. At this time, the support column 1 2 is pushed to the right to move it closer to the support column 2 3. At this time, the storage folding plate 22 gradually shrinks until the support column 1 2 reaches the outer surface of the fixing rod 26, and then the connecting cross bar 27 is rotated downward to complete the storage action.

[0030] The following is a detailed description of the working principle of the construction guardrail that is easy to fold and store.

[0031] like Figure 1-5 As shown, when in use, the support column 23 can be pulled to gradually move away from the support column 1 2. At this time, the storage folding plate 22 itself can adjust the horizontal length as needed. After adjustment, the fixing ring 1 29 and the fixing ring 2 210 on both sides of the top of the support column 1 2 are rotated so that the two rotate on the outer surface of the external thread 28 and fit tightly on both sides of the support column 1 2. The fixing rod 26 and the connecting cross bar 27 are used to fix the guardrail after the length is adjusted. When not in use, the fixing ring 1 29 is rotated to disengage from the external thread 28 and pull it onto the outer surface of the fixing rod 26. At this time, the support column 1 2 is pushed to the right to make it close to the support column 2 3. At this time, the storage folding plate 22 gradually shrinks until the support column 1 2 reaches the outer surface of the fixing rod 26, and then the connecting cross bar 27 is rotated downward to complete the storage action.

[0032] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
