Description

Technical Field

[0001] The utility model relates to the field of foldable guardrails, in particular to a foldable guardrail for building construction. Background Art

[0002] During the construction process, safety issues must be considered at all times. In order to prevent non-staff from entering the construction site and causing safety accidents or to isolate dangerous construction areas, construction workers often use guardrails for protection. Guardrails for construction play a vital role in the construction process. They are not only used to isolate the construction area and protect the safety of construction workers and passers-by, but also serve as warnings and guides. In the existing patent application with application number CN202122063373.1, a folding temporary guardrail for construction is proposed. Although it can flexibly adjust the maintenance range of the fence through the adjustment of the quadrilateral folding structure and the screw structure, the guardrail can only be pulled open in a straight line and arranged in a straight line, so that the guardrail can only enclose one side, and construction sites often require multi-sided enclosures. Therefore, the practicality of the guardrail is poor, so it needs to be improved. Summary of the Invention

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, a foldable guardrail for construction includes two folding guardrail bodies 1, and a connecting component 2 is fixedly installed on the two folding guardrail bodies 1. The connecting component 2 consists of a fixed base plate 6, a mounting base block 7 and a rotating connecting column 9. The mounting base block 7 is fixedly installed on the upper end of the fixed base plate 6. There are two rotating connecting columns 9 and both are rotatably installed on the mounting base block 7. A first fixing component 3 is fixedly sleeved on the rotating column 9. The first fixing component 3 consists of a fixing sleeve 10 and a fixing clip 11. There are several fixing clips 11 and they are annularly distributed on the outer wall of the fixing sleeve 10. A second fixing component 4 is fixedly installed on the upper end of the mounting base block 7. The second fixing component 4 is simultaneously sleeved on the two rotating connecting columns. The connecting column and the outside of the two first fixing components 3, the second fixing component 4 is composed of a return spring 12 and a fixed card plate 13, the fixed card plate 13 is fixedly installed on the upper end of the return spring 12, and a movable support vertical rod 5 is fixedly installed on the two folding guardrail bodies 1. When the guardrail needs to be used to enclose the construction site, the folding guardrail body 1 can be stretched open by the movable support vertical rod 5. When the guardrail needs to be used to enclose both sides of the construction site, one of the folding guardrail bodies 1 can be horizontally rotated with the rotating connecting column 9 connected to it as the axis, so that the two folding guardrail bodies 1 are at a certain angle, thereby making the two folding guardrail bodies 1 respectively located at the construction site. When the folding guardrail body 1 is rotated horizontally, the fixing plate 13 on the second fixing assembly 4 needs to be pushed downward, so that the fixing plate 13 is disengaged from the first fixing assembly 3. At this time, the fixing of the folding guardrail body 1 is released, and the folding guardrail body 1 can be rotated horizontally. When the folding guardrail body 1 is rotated horizontally, the fixing plate 13 is released, so that the fixing plate 13 is sleeved on the first fixing assembly 3 under the elastic force of the return spring 12. At this time, the folding guardrail body 1 is fixed. In this state, the rotating connecting column 9 cannot rotate horizontally. By arranging a connecting component 2 on the two folding guardrail bodies 1, the guardrail can be bent from the middle, so that the guardrail can be bent at a certain angle, and then the guardrail can be used to enclose two sides, which ultimately makes the guardrail more practical. By arranging a first fixing component 3 on the rotating connecting column 9 and a second fixing component 4 on the mounting base block 7, so that they cooperate with each other, the rotating connecting column 9 can be conveniently fixed, so that the bending angle of the guardrail can be fixed after the bending adjustment is completed, thereby avoiding the bending angle of the guardrail being affected by external forces after the bending adjustment is completed. Changes are ultimately more conducive to the use of the guardrail.

[0021] Furthermore, two mounting connection grooves 8 are symmetrically opened at the upper end of the mounting base block 7 on the connecting component 2, and the two rotating connecting columns 9 on the connecting component 2 are respectively rotatably installed in the two mounting connection grooves 8, and the rotating connecting columns 9 are fixedly connected to the folding guardrail main body 1. The rotating connecting column 9 can rotate horizontally in the mounting connection groove 8. When the angle between the two folding guardrail main bodies 1 needs to be adjusted, the rotating connecting column 9 can be horizontally rotated in the mounting connection groove 8.

[0022] Furthermore, the fixing sleeve 10 on the first fixing component 3 is fixedly connected to the fixing card strip 11, the fixing sleeve 10 is fixedly sleeved on the rotating connecting column 9, the return spring 12 on the second fixing component 4 is fixedly mounted on the upper end of the mounting base 7, and the return spring 12 is simultaneously sleeved on the outer side of the two rotating connecting columns 9, and the fixing card plate 13 is symmetrically provided with two set through holes 14, and the inner wall of the set through hole 14 is provided with a plurality of set card slots 15, and the set through hole 14 and the set card slot 15 both pass through the fixing card plate 13 up and down, and the two set through holes 14 of the fixing card plate 13 are simultaneously sleeved on the two fixing sleeves 10, and the fixing card plate 13 can be sleeved through the set card slot 15 On the fixed clip 11, when the fixed clip 13 is pushed downward and disengaged from the first fixed component 3, the return spring 12 will be compressed by the fixed clip 13. At this time, the fixation of the rotating connecting column 9 will be released. At this time, when the rotating connecting column 9 rotates horizontally, the first fixed component 3 can rotate together with the rotating connecting column 9. When the fixed clip 13 is released, under the elastic force of the return spring 12, the fixed clip 13 will move upward. Finally, when the fixed clip 13 is mounted on the first fixed component 3, that is, the fixed sleeve 10 is located in the set through hole 14, and the fixed clip 11 is located in the set slot 15, the rotating connecting column 9 will be fixed and cannot be rotated horizontally.
