The adjustable guardrail for construction, by means of the sliding connection between the first box body and the second box body and the sliding rod, can adjust the overall height of the device according to the height of the construction site, by means of the first threaded rod driving the first connecting plate and the second connecting plate to fold, the length of the device can be adjusted according to the site area of ​​the construction site, and by means of connecting columns and connecting sleeves, multiple devices can be spliced ​​together, which can be applicable to construction sites with larger areas, improve the applicability of the device, and at the same time reduce the volume of the device for easy transportation. However, the guardrail has the following disadvantages during use:

[0004] After the above-mentioned guardrail is installed, it is difficult for personnel to move the guardrail again. It is not flexible enough in use and has high limitations. In some construction sites, the guardrail not only blocks irrelevant personnel from approaching, but also hinders workers from using carts to transport materials, etc., requiring many workers to carry out the transportation, which is time-consuming and labor-intensive, wastes a lot of human resources, and reduces work efficiency. Therefore, the utility model provides an adjustable construction safety guardrail. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Example

[0030] like Figure 1-4As shown, an adjustable construction safety guardrail includes a fixed pile 1, a foldable protective fence 2 is hinged on one side of the fixed pile 1, a movable pile 3 is hinged on one side of the foldable protective fence 2, a fixed pile 2 4 is sleeved on one side of the movable pile 3, and a limiting groove 41 is provided on the inner wall of the fixed pile 2 4;

[0031] A chamber 31 is provided inside the movable pile 3, and a pair of connecting rings 32 are fixedly connected to the inner wall of the chamber 31, and a connecting rod 33 is passed through and movably connected in the pair of connecting rings 32, and a clamping block 35 is fixedly connected to one end of the connecting rod 33, and one end of the clamping block 35 passes through the chamber 31 and is engaged with the limiting groove 41, and a spring 34 is fixedly connected to the other end of the clamping block 35, and one end of the spring 34 is fixed to the connecting ring 32, and the ends of the pair of connecting rods 33 close to each other are fixedly connected to metal fiber ropes 37, and a return handle 36 is passed through and movably connected on the upper side of the movable pile 3, and the return handle 36 is connected to the metal fiber rope 37;

[0032] One side of the block 35 is inclined.

[0033] When in use, after the fixed pile 1 is installed on the ground, the fixed pile 2 4 is moved, and the foldable protective fence 2 can be stretched and adjusted, which can be applied to different construction sites to meet the needs of users. The foldable protective fence 2 is spliced ​​with the fixed pile 2 4 through the movable pile 3. When personnel need to pass, the movable pile 3 can be disassembled, and the foldable protective fence 2 can be retracted by moving the movable pile 3. Then the personnel can push the trolley to pass between the fixed pile 1 and the fixed pile 2 4. It can be flexibly applied to different construction scenes. Even if multiple safety guardrails are combined to protect the construction site, personnel can flexibly choose the shortest path to open the safety guardrail to transport materials, thereby reducing personnel physical exertion and improving work efficiency.

[0034] When the personnel need to disassemble the movable pile 3, they first pull the return handle 36, which cooperates with the metal fiber rope 37 to shrink the block 35, so that the block 35 is separated from the limiting groove 41. Then, the personnel pulls the return handle 36 to one side to drive the movable pile 3 to move. When the movable pile 3 is subsequently reset, since one side of the block 35 is inclined, after the movable pile 3 is reset into place, the block 35 can be directly embedded in the limiting groove 41, which is convenient for personnel to operate.

[0035] like Figure 1-2 As shown, notches 42 are provided on both sides of the second fixing pile 4 , and the notches 42 correspond to the return handles 36 .

[0036] During use, when the movable pile 3 is reset, the return handle 36 is exactly aligned with the notch 42 to prevent the return handle 36 from being interfered by the fixed pile 24, which would cause the movable pile 3 to fail to reset.

[0037] like Figure 1-2 As shown, the lower ends of the fixing pile 1 and the fixing pile 2 4 are fixedly connected to a base 1 5 , and the four corners of the base 1 5 are penetrated and movably connected with nail pins 6 .

[0038] During use, when the fixing pile 1 and the fixing pile 2 4 are placed on the ground, the nail pin 6 can be hammered into the ground to improve the stability of the fixing pile 1 and the fixing pile 2 4 placed on the ground.

[0039] like Figure 1-2 As shown, the lower end of the movable pile 3 is fixedly connected to a base 2 7 , and a roller 8 is provided at the lower end of the base 2 7 .

[0040] When in use, the roller 8 can reduce the friction between the movable pile 3 and the ground, thereby making it easier for people to move the movable pile 3.

[0041] like Figure 4 As shown, a support rod 39 is fixedly connected to the inner wall of the chamber 31 , and one end of the support rod 39 is rotatably connected to a steering wheel 391 , and the outer circumferential surface of the steering wheel 391 is in contact with the metal fiber rope 37 .

[0042] When in use, the metal fiber rope 37 can be limited by the support rod 39 and the steering wheel 391 to prevent the metal fiber rope 37 from tilting too much when the metal fiber rope 37 is pulled, resulting in the block 35 being unable to be retracted.

[0043] like Figure 4 As shown, both sides of the movable pile 3 are fixedly connected with a reinforcement sleeve 38 , and the reinforcement sleeve 38 is sleeved on the outer circumferential surface of the return handle 36 .

[0044] When in use, the reinforcing sleeve 38 is used to improve the stability of the connection between the movable pile 3 and the return handle 36, so that the connection between the movable pile 3 and the return handle 36 is not easily deformed.

[0045] In summary, the specific working process of this solution is as follows: after the fixed pile 1 is installed on the ground, the fixed pile 2 4 is moved, and the foldable protective fence 2 can be stretched and adjusted, which can be applied to different construction sites to meet the needs of users. The foldable protective fence 2 is spliced ​​with the fixed pile 2 4 through the movable pile 3. When personnel need to pass, the movable pile 3 can be disassembled, and the foldable protective fence 2 can be retracted by moving the movable pile 3. Then the personnel can push the trolley to pass between the fixed pile 1 and the fixed pile 2 4. It can be flexibly applied to different construction scenes. Even if multiple safety guardrails are combined to protect the construction site, personnel can flexibly choose the shortest path to open the safety guardrail to transport materials, reduce personnel physical exertion, and improve work efficiency.

[0046] Among them, when the personnel need to disassemble the movable pile 3, they first pull the return handle 36, and the return handle 36 cooperates with the metal fiber rope 37 to shrink the block 35, so that the block 35 is separated from the limiting groove 41, and then the personnel pulls the return handle 36 to one side to drive the movable pile 3 to move. When the movable pile 3 is subsequently reset, since one side of the block 35 is inclined, after the movable pile 3 is reset into place, the block 35 can be directly embedded in the limiting groove 41, which is convenient for personnel to operate and use.

[0047] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
