[0002] Construction guardrails, also known as enclosures, are a type of safety facility used to guard against accidents around construction sites or foundation pits. During the construction process, due to the presence of exposed deep pits or large mechanical equipment at the construction site, it is easy to cause danger to people, vehicles, and objects. Therefore, safety guardrails need to be set up to enclose the construction site to ensure the safety of construction workers and passers-by.

[0003] When existing construction safety guardrails are in use, some construction protection areas are relatively large, and generally multiple safety guardrails need to be placed to enclose the construction area. However, some areas need to be enclosed by multiple guardrails, and there is often a lack of good connection methods between the guardrails. Some traditional safety guardrails have low connection flexibility and poor stability. Therefore, the utility model provides a construction safety guardrail. Utility Model Content

However, some areas need to be enclosed by multiple guardrails, and there is often a lack of good connection methods between the guardrails. Some traditional safety guardrails have low connection flexibility and poor stability.

[0006] 2. Technical solution

[0007] In order to solve the above problems, the present invention adopts the following technical solutions.

[0008] A construction safety guardrail comprises a guardrail frame, wherein one side of the guardrail frame is fixedly connected to a connecting member 1 and a connecting member 2, the upper end of the connecting member 1 is rotatably connected to a connecting shaft, the upper end of the connecting shaft passes through the connecting member 2 and extends, the outer circumferential surface of the connecting shaft is fixedly connected to a splicing frame, the upper end of the splicing frame passes through and is movably connected to a latch, the upper end of the latch is fixedly connected to a spring, the lower end of the spring is fixed to the upper end of the splicing frame, the other side of the guardrail frame is fixedly connected to a splicing block, the upper end of the splicing block is provided with a limiting groove, the splicing block matches the splicing frame, and the limiting groove matches the latch.

[0009] Furthermore, the upper end of the connecting shaft is hollow, and four impact blocks are provided on the upper end of the connecting shaft. One side of the four impact blocks is in contact with the inner wall of the connecting member 2, and the other side of the four impact blocks is fixedly connected with a return spring, one end of the return spring is fixed to the inner wall of the connecting shaft, and the upper end of the connecting shaft is threadedly connected with a screw, and the lower end of the screw is in contact with the impact block.

[0010] Furthermore, the lower end of the screw is in a cone shape.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example

[0025] like Figure 1-4 As shown, a construction safety guardrail includes a guardrail frame 1, one side of the guardrail frame 1 is fixedly connected with a connecting member 2 and a connecting member 3, the upper end of the connecting member 2 is rotatably connected with a connecting shaft 4, the upper end of the connecting shaft 4 passes through the connecting member 2 3 and extends, the outer circumferential surface of the middle section of the connecting shaft 4 is fixedly connected with a splicing frame 5, the upper end of the splicing frame 5 passes through and is movably connected with a pin 6, the upper end of the pin 6 is fixedly connected with a spring 7, the lower end of the spring 7 is fixed to the upper end of the splicing frame 5, the other side of the guardrail frame 1 is fixedly connected with a splicing block 8, the upper end of the splicing block 8 is provided with a limiting groove 801, the splicing block 8 matches the splicing frame 5, and the limiting groove 801 matches the pin 6.

[0026] When in use, after the safety guardrail is placed at the edge of the construction area, the splicing blocks 8 between adjacent safety guardrails can be inserted into the splicing frame 5, and then the splicing frame 5 and the splicing blocks 8 are kept stably connected through the pin 6. When the safety guardrail encloses the construction area, since each safety guardrail is spliced ​​together, all the safety guardrails can form a whole, which can greatly improve the overall strength and thus improve the protection effect.

[0027] like Figure 2-3 As shown, the upper end of the connecting shaft 4 is hollow and is provided with four abutting blocks 401. One side of each of the four abutting blocks 401 contacts the inner wall of the connecting member 2 3. The other side of each of the four abutting blocks 401 is fixedly connected to a return spring 402. One end of the return spring 402 is fixed to the inner wall of the connecting shaft 4. The upper end of the connecting shaft 4 is threadedly connected to a screw 403. The lower end of the screw 403 contacts the abutting blocks 401. The abutting blocks 401 can be made of a material such as rubber, and their outer surface is provided with anti-slip particles.

[0028] During use, the angles of adjacent safety guardrails can be adjusted. After the angle adjustment is completed, the screw 403 is rotated. The screw 403 will squeeze the locking block 401 during the downward movement, and the locking block 401 will eventually press tightly against the inner wall of the connecting piece 2 3. At this time, there is a large static friction between the locking block 401 and the connecting piece 2 3 to prevent the two from rotating, so that the safety guardrail after the angle adjustment is completed can be locked at the required angle to ensure the stability of the safety guardrail. The spliced ​​safety guardrail that can be adjusted in angle can not only ensure its overall strength, but also improve its adaptability to construction areas of different shapes to meet the user's usage needs.

[0029] like Figure 3 As shown, the lower end of the screw 403 is conical.

[0030] During use, the screw rod 403 with a conical lower end can better push the pressing block 401 toward the surroundings during the downward movement, ensuring that the pressing block 401 can tightly press against the inner wall of the second connecting member 3.

[0031] like Figure 4 As shown, a pair of support blocks 101 are fixedly connected to one side of the guardrail frame 1, and the support blocks 101 are in a triangular shape.

[0032] When in use, the support block 101 can increase the contact area between the guardrail frame 1 and the ground, thereby improving the stability of the guardrail frame 1 on the ground. It should be noted that the present invention is mainly used in locations with stable ground. If there are uneven ground near the construction area, the support block 101 structure can be improved in a targeted manner in future technological developments. Such terrain is not within the scope of application of the present invention.

[0033] like Figure 4 As shown, a notch 102 is provided on the inner wall of the guardrail frame 1 , and a warning sign 9 is embedded in the notch 102 . The upper end of the warning sign 9 passes through and extends from the upper end of the guardrail frame 1 , and a handle 901 is fixedly connected to the upper end of the warning sign 9 .

[0034] When in use, a warning slogan can be printed on the warning sign 9 to remind the staff on site. When the warning slogan is to be replaced later, the warning sign 9 can be easily disassembled.

[0035] In summary, the specific working process of this solution is as follows: after the safety guardrail is placed at the edge of the construction area, the splicing blocks 8 between adjacent safety guardrails can be inserted into the splicing frame 5, and then the splicing frame 5 and the splicing blocks 8 are kept stably connected by the latch 6. When the safety guardrail encloses the construction area, since each safety guardrail is spliced ​​together, all the safety guardrails can form a whole, which can greatly improve the overall strength and thus improve the protection effect;

[0036] Among them, the angles between adjacent safety guardrails can be adjusted. After the angle adjustment is completed, the screw 403 is rotated. The screw 403 will squeeze the pressing block 401 during the downward movement. The pressing block 401 will eventually press tightly against the inner wall of the connecting piece 2 3, so that the safety guardrail after the angle adjustment is completed can be locked at the required angle to ensure the stability of the safety guardrail. The spliced ​​safety guardrail that can be adjusted in angle can not only ensure its overall strength, but also adapt to the edge installation of construction areas of different shapes, which can greatly meet the user's usage needs.

[0037] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
