Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A construction safety device includes support columns 1 and guardrails 2. The guardrails 2 are positioned between two support columns 1. Each support column 1 includes a base 11, with a column 12 fixedly connected to the top of the base 11. Connecting wing plates 13 are symmetrically fixedly connected to both sides of the column 12. Connecting wing plates 13 have connecting grooves 131, and vertical rods 14 are elastically connected to the connecting wing plates 13 via springs 15. The guardrails 2 include a protective frame 21, with railings 22 fixedly connected inside the protective frame 21. The guardrails 2 are positioned with connecting grooves 131 on both sides of the protective frame 21. The frame 21 is fixedly connected with a connecting support 23, which is rotatably connected to the connecting wing plate 13 via a vertical rod 14. Two connecting grooves 131 are provided vertically on the connecting wing plate 13. Two connecting supports 23 are provided vertically on each side of the protective frame 21. The connecting supports 23 are connected to the connecting grooves 131. A connecting rod 141 is fixedly installed on the side wall of the vertical rod 14, and two connecting rods 141 are provided vertically on the vertical rod 14. The lower ends of the two connecting rods 141 respectively movably pass through the two connecting grooves 131. The connecting support 23 placed in the middle allows the connecting support 23 to rotate around the connecting rod 141, thereby enabling flexible adjustment of the angle between two adjacent guardrails 2. A limiting circular plate 142 is fixedly installed in the middle of the vertical rod 14, and the limiting circular plate 142 slides along the groove opened inside the connecting wing plate 13. A spring 15 is sleeved on the vertical rod 14, with the lower end of the spring 15 abutting against the limiting circular plate 142 and the upper end of the spring 15 abutting against the top of the groove. The upper end of the vertical rod 14 extends to the connecting wing plate 13. A handle 143 is fixedly installed on the outside of the plate 13. By pulling the vertical rod 14 upward, the connecting rod 141 is moved upward and removed from the connecting support 23, so that the guardrail 2 and the support column 1 can be quickly separated. By pulling the vertical rod 14 upward and placing the connecting support 23 in the connecting groove 131, the spring force of the spring 15 can drive the vertical rod 14 downward, so that the lower end of the connecting rod 141 can move through the connecting support 23, so that the guardrail 2 and the support column 1 can be quickly connected. The operation is convenient.

[0022] Construction warning boards 3 are fixed on the guardrail 2 by L-shaped limiting brackets 24 and support bars 25. L-shaped limiting brackets 24 are symmetrically fixed to the front and rear sides of the middle part of the guardrail 21, and support bars 25 are symmetrically fixed to the front and rear sides of the lower part of the guardrail 21. The construction warning boards 3 are inserted between the two L-shaped limiting brackets 24, and the bottom of the construction warning boards 3 rests on the top of the support bars 25. By inserting the construction warning boards 3 between the two L-shaped limiting brackets 24, construction warning boards 3 can be placed on the front and rear sides of the guardrail 2 as needed. Thus, the two construction warning boards 3, one inside and one outside, can provide safety warnings to personnel outside the guardrail and construction workers respectively, resulting in better usage.

[0023] Working principle: When using the protective device, the handle 143 can be manually pulled upwards to move the vertical rod 14 upwards. The upward movement of the vertical rod 14 can move the limiting circular plate 142 upwards, compressing the spring 15 and causing the connecting rod 141 to move away from the connecting groove 131. Then, the connecting supports 23 on one side of the protective frame 21 are placed in the corresponding connecting grooves 131, and the handle 143 is released. At this time, under the elastic force of the spring 15, the vertical rod 14 can be moved downwards to reset, thereby causing the connecting rod 141 to move downwards through the connecting groove. Connect the support 23 to quickly connect the guardrail 2 to the support column 1. When it is necessary to disassemble the protective device, manually pull the handle 143 upward to move the vertical rod 14 upward, so that the connecting rod 141 can be moved out of the connecting support 23. Then the connecting support 23 can be moved out of the connecting groove 131, and the guardrail 2 can be quickly separated from the support column 1. By inserting the construction warning board 3 between a set of L-shaped limit brackets 24 and placing the bottom of the construction warning board 3 on the support bar 25, the construction warning board 3 can be used to warn personnel about construction safety, which can better maintain construction safety.
