Description

Technical Field

[0001] This utility model relates to the field of protective fences, specifically to a simple prefabricated protective fence for construction sites. Background Technology

[0002] A construction site is a location where a construction project is underway, typically involving civil engineering. It encompasses all areas on land, at sea, and in the air suitable for construction work, including building construction, civil engineering, equipment installation, and pipeline laying for industrial and civil projects. Safety measures are extremely important on construction sites because construction activities involve numerous potential risks. Therefore, construction workers must receive relevant safety training and education to ensure the smooth progress of construction activities and the safety of personnel. Protective fencing is frequently used to cordon off certain areas on construction sites.

[0003] Existing construction site safety fences mostly have welded and fixed support legs, which are set vertically to the fence to ensure stable support. However, they cannot be folded to reduce volume, which is not conducive to the bulk storage and movement of the fence. In addition, warning lights and other components are usually installed on the fence to ensure nighttime protection, but the fences are mostly not convenient for quick installation and removal of warning lights, making them inconvenient to use. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A simple prefabricated protective fence for construction sites includes a frame, a protective net, and a solar-powered warning light. The top of the frame has an insertion hole, and the interior of the frame has a mounting groove located on the side of the insertion hole. The bottom of the solar-powered warning light is fixedly connected to a plug block, which is movably engaged inside the insertion hole. A fixing component is movably installed inside the mounting groove. The frame includes a body, with connecting rods and connecting blocks fixedly connected to its left and right sides respectively. The connecting blocks have locking holes corresponding to the connecting rods inside. Grooves are formed on the lower left and right sides of the body, with rotating shafts movably engaged inside each groove. Connecting sleeves are movably fitted onto the outside of the rotating shafts, and support plates are fixedly connected to the outside of the connecting sleeves.

[0006] A further improvement of the present invention is that the fixing component includes a slider and a support spring that are movably engaged inside the mounting groove. The support spring is engaged on the outside of the slider. A limiting block is fixedly connected to the inside of the slider. The limiting block extends into the insertion hole. A pull plate located outside the frame is fixedly connected to the rear side of the slider.

[0007] A further improvement of this utility model is that the groove and the rotating shaft are located symmetrically arranged at the bottom of the frame.

[0008] A further improvement of this utility model is that the cross-section of the support plate is T-shaped.

[0009] A further improvement of this utility model is that: a fixing hole is provided at the bottom of the support plate, and a cutting rod is movably installed inside the fixing hole.

[0010] A further improvement of this utility model is that: the outer side of the insert block is provided with a slot corresponding to the limiting block, and the limiting block is movably engaged with the inside of the insert block.

[0011] A further improvement of this utility model is that the protective net is fixedly installed on the inside of the frame.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a simple prefabricated protective fence for construction sites. The connecting rod can be inserted into the locking hole in the connecting block to facilitate the quick assembly and connection of multiple fences. The supporting plate can drive the connecting sleeve to rotate outward along the rotating shaft in the groove, and can be folded and fitted to the front and rear sides of the frame to reduce its space occupation. Multiple frames can be stacked together for easy storage and quick transfer, improving convenience and flexibility.

[0014] 2. This utility model provides a simple prefabricated protective fence for construction sites. By pulling the pull plate outward, the pull plate drives the slider located in the installation groove to slide outward. The slider moves the limiting block outward and squeezes the support spring. Then, by inserting the solar warning light into the hole using the bottom plug, the pull plate is released and the elastic force of the support spring pushes the slider inward. The slider drives the limiting block to pass into the hole and lock into the inside of the plug for limiting and fixing. This facilitates the quick assembly and disassembly of the solar warning light and improves the convenience of use. Attached Figure Description

[0021] The present invention will now be described in further detail:

[0022] like Figures 1 to 5 As shown, this utility model provides a simple prefabricated protective fence for construction sites, including a frame 1, a protective net 2, and a solar warning light 3. The top of the frame 1 has an insertion hole 4, and the inside of the frame 1 has an installation groove 5 located on the side of the insertion hole 4. The bottom of the solar warning light 3 is fixedly connected to an insertion block 6, which is movably engaged inside the insertion hole 4. A fixing component 7 is movably installed inside the installation groove 5. The frame 1 includes a frame body 11, and the left and right sides of the frame body 11 are respectively fixedly connected to a connecting rod 14 and a connecting block 12. The inside of the connecting block 12 has a locking hole 13 corresponding to the connecting rod 14. The lower part of the left and right sides of the frame body 11 has a groove 15, and the inside of the groove 15 is movably engaged with a rotating shaft 16. The outside of the rotating shaft 16 is movably sleeved with a connecting sleeve 17, and the outside of the connecting sleeve 17 is fixedly connected with a support plate 18.

[0023] The connecting rod 14 can be inserted into the locking hole 13 in the connecting block 12 to facilitate the quick assembly and connection between multiple fences. The supporting plate 18 can drive the connecting sleeve 17 to rotate outward along the rotating shaft 16 in the groove 15, which can be folded and fitted to the front and rear sides of the frame 11 to reduce its space occupation. Multiple frames 11 can be stacked together for easy storage and quick transfer, improving convenience and flexibility.

[0024] like Figure 3 and Figure 4 As shown, the fixing component 7 includes a slider 71 that is movably engaged inside the mounting groove 5 and a support spring 72. The support spring 72 is engaged on the outside of the slider 71. A limiting block 73 is fixedly connected to the inside of the slider 71. The limiting block 73 extends into the insertion hole 4. A pull plate 74 located outside the frame 1 is fixedly connected to the rear side of the slider 71.

[0025] By pulling the pull plate 74 outward, the pull plate 74 causes the slider 71 located in the mounting groove 5 to slide outward. The slider 71 moves the limiting block 73 outward, squeezing the support spring 72. Then, by inserting the solar warning light 3 into the socket 4 using the bottom insert 6, after releasing the pull plate 74, the elastic force of the support spring 72 pushes the slider 71 to slide inward. The slider 71 causes the limiting block 73 to pass into the socket 4 and lock into the insert 6 for limiting and fixing. This facilitates the quick assembly and disassembly of the solar warning light 3, improving the ease of use.

[0026] like Figure 2 As shown, the groove 15 and the rotating shaft 16 are located symmetrically arranged at the bottom of the frame 11.

[0027] The groove 15 and the rotating shaft 16 are arranged symmetrically front and back, so that the support plate 18 can be adjusted to be parallel or perpendicular to the frame 11 by rotating around the rotating shaft 16, which facilitates the batch stacking and transportation of the frame 11.

[0028] like Figure 2 As shown, the cross-section of the support plate 18 is T-shaped.

[0029] like Figure 2 As shown, a fixing hole 19 is provided at the bottom of the support plate 18, and a cutting rod 110 is movably installed inside the fixing hole 19.

[0030] The support plate 18 has a "T" shaped cross section to provide stable support, and the insertion rod 110 installed in the fixing hole 19 is inserted into the ground to ensure the fixing effect.

[0031] like Figure 4 As shown, the outer side of the insert 6 has a slot corresponding to the limiting block 73, and the limiting block 73 is movably engaged with the inside of the insert 6.

[0032] The slot on the outside of the insert 6 corresponds to the limiting block 73. The limiting block 73 is inserted into the slot to limit the position of the insert 6 and ensure the stability of the connection.

[0033] like Figure 1 As shown, the protective net 2 is fixedly installed on the inside of the frame 1.

[0034] The protective netting 2 is installed inside the frame 1 to provide protection while reducing the overall weight.

[0035] The working principle of the simple prefabricated protective fence at the construction site will be explained in detail below.

[0036] like Figures 1 to 5As shown, during use, by prying outwards the support plates 18 on both sides of the bottom of multiple frames 1, the connecting sleeve 17 is rotated outwards along the rotating shaft 16 in the groove 15. At this time, the support plates 18 are perpendicular to the frame 11, providing stable support for the frame 11. By inserting the connecting rod 14 on one side of the frame 11 into the locking hole 13 on the side of another frame 11 from above, the quick splicing assembly between the two frames 1 is completed. After the multiple frames 1 are assembled and placed, the insert rod 110 is passed through the fixing hole 19 and fixed to the ground for protection. Pulling the pull plate 74 outward causes the slider 71 located in the mounting groove 5 to slide outward. The slider 71 moves the limiting block 73 outward, squeezing the support spring 72. Then, by inserting the solar warning light 3 into the socket 4 using the bottom insert 6, after releasing the pull plate 74, the elastic force of the support spring 72 pushes the slider 71 inward. The slider 71 drives the limiting block 73 to pass into the socket 4 and lock into the insert 6 for limiting and fixing. The solar warning light 3 uses solar energy to store electrical energy in the battery during the day and flashes at night to serve as a warning.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
