They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 As shown, a novel protective device for civil construction includes a rectangular fence-type guardrail 1 enclosed by a top plate, a bottom plate, a left side plate, and a right side plate. A set of positioning holes 3 arranged in a ring are respectively opened on the left and right sides of the top plate of the guardrail. A first connecting mechanism 4 is fixedly connected to the upper and lower parts of the outer side of the left side plate, and a second connecting mechanism 5 is fixedly connected to the upper and lower parts of the outer side of the right side plate. The guardrail can be spliced ​​piece by piece through the cooperation of the first connecting mechanism 4 and the second connecting mechanism 5. Fixing mechanisms 6 are respectively installed in the fence openings 7 on the left and right sides of the guardrail, and rollers 8 are installed on the bottom plate to facilitate the movement of the guardrail.

[0019] The fixing mechanism 6 is as follows Figure 2As shown, the guardrail includes a slotted positioning frame with its opening facing downwards, a screw hole in the middle of the top plate 65 of the slotted positioning frame, a cylindrical rod 61 that passes vertically through the hole and has a screw at the bottom, a limiting plate 62 fitted onto the lower part of the cylindrical rod, an end plate 63 fixed to the upper end of the cylindrical rod, a positioning pin 64 installed on the end plate and passing downwards through the end plate, and a handle 66 installed on the end plate. The upper end of the cylindrical rod 61 passes through the center of the annular ring of the positioning holes 3 and exits the top plate of the guardrail. The end plate 63, the positioning pin 64, and the handle 66 are all located outside the top plate. The positioning pin 64 can be inserted into any of the positioning holes 3 for positioning according to the construction site conditions. The two side plates 67 of the slotted positioning frame are triangular plates with their pointed corners facing downwards. The pointed bottom ends of the triangular plates are located at the front and back of the bottom plate of the guardrail. Rotating the cylindrical rod 61 moves the lower slotted positioning frame downwards or upwards. When the guardrail needs to be fixed, adjusting the slotted positioning frame downwards causes the bottom tip of the triangular plate to insert into the ground to a certain depth, thus securing the guardrail. Reversing the rotation of the cylindrical rod removes the triangular plate from the ground, allowing for quick disassembly of the guardrail. The limiting plate 62 is located on the top plate 65 of the slotted positioning frame, effectively preventing the limiting plate from slipping out of the screw range.

[0020] The first connecting mechanism 4, as described Figure 3 As shown, it includes a first groove-shaped frame 41 with the groove opening facing outward, a vertical first cylindrical tube 42 fixedly welded to the back plate of the first groove-shaped frame, a telescopic rod 43 that vertically passes through the upper and lower groove plates of the first groove-shaped frame and has a baffle 47 at the top, a spring 44 that is fitted on the telescopic rod and located outside the first groove-shaped frame, a first connecting shaft 45 that is vertically inserted into the first cylindrical tube 42, and first mounting ears 46 that are respectively fitted at both ends of the first connecting shaft. The first mounting ears 46 are welded to the outside of the left side plate of the guardrail.

[0021] The second connecting mechanism 5 is as follows Figure 4 As shown, it includes a second groove frame 51 with the groove opening facing outward, a vertical second cylindrical tube 52 fixedly welded to the back plate of the second groove frame, a second connecting shaft 53 vertically inserted into the second cylindrical tube 52, second mounting ears 54 respectively fitted on both ends of the second connecting shaft, and through holes 55 opened on the upper and lower groove plates of the second groove frame for the telescopic rod 43 to pass through. The second mounting ears 54 are welded to the outside of the right side plate of the guardrail.

[0022] By inserting the second slot frame 51 of one guardrail into the first slot frame 41 of another guardrail (when the height of the second slot frame is less than the height of the first slot frame 41), and inserting the telescopic rod 43 of the first connecting mechanism 4 through the first slot frame 41 and the second slot frame 51, the guardrails can be spliced ​​together piece by piece. As an equivalent technical means, it can also be designed so that the height of the first slot frame is less than the height of the second slot frame, and the first slot frame is inserted into the second slot frame, or the upper and lower slot plates of the first and second slot frames can be staggered. These are all installation methods that can be understood by those skilled in the art.

[0023] Since the first connecting shaft 45 is vertically inserted into the first cylindrical tube 42 and can rotate freely, and the second connecting shaft 53 is also vertically inserted into the second cylindrical tube 52 and can rotate freely as well, the two sets of guardrails can be flexibly rotated and adjusted according to the specific usage scenario, thereby improving the installation flexibility and the applicability of the construction scenario.

[0024] Reflectors 2 are installed on the upper front and upper back of the guardrail to serve as a warning.

[0025] In use, the first guardrail 1 is moved to the desired protective position. The positioning pin 64 is pulled out of the positioning hole 3. Then, the handle 66 of the positioning mechanism 6 is held and the cylindrical rod 61 is rotated. As the cylindrical rod rotates, the lower screw section drives the slotted positioning frame downward, pushing the triangular plate down into the ground like a ground cone, thus fixing the first guardrail. The positioning pin 64 is then inserted into the nearby positioning hole 3 to fix the positioning mechanism. Next, the second slotted frame 51 of the second guardrail is inserted into the first slotted frame 41 of the first guardrail. The telescopic rod 43 is inserted through the first and second slotted frames 41 to connect the second guardrail to the first guardrail. The installation angle of the second guardrail is adjusted. Then, the handle 66 of the fixing mechanism on the second guardrail is held and the cylindrical rod 61 is rotated, pushing the triangular plate down into the ground to fix the second guardrail. The positioning pin 64 on the second guardrail is then inserted into the nearby positioning hole 3 to fix the positioning mechanism. Continue assembling the remaining bottom guardrails piece by piece using the method described above. When it is necessary to remove the guardrail, remove the positioning pin 64, rotate the cylindrical rod 61 in the opposite direction to lift the triangular plate off the ground, remove the telescopic rod, and the guardrail can be disassembled quickly and easily.

[0026] The foregoing has shown and described the technical solution and basic principles of this utility model. Those skilled in the art should understand that the scope of protection of this utility model is not limited to the above embodiments. Any equivalent technical means substitutions made to this utility model without departing from its technical essence are within the scope of protection of this utility model.
