DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantage of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0024] The technical scheme of the utility model will be described in detail below with specific embodiments. The following several specific embodiments can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some embodiments.

[0025] As Figures 1 to 5 shown, the utility model provides a kind of building road foundation pit safety protection device, a kind of building road foundation pit safety protection device, including guardrail body 1, support column 2 being equipped in the both sides of the guardrail body 1, the bottom of the guardrail body 1 is equipped with folding base 3, the folding base 3 includes directional plate 31, two pieces of lateral plate 32 respectively hinged in the both sides of the directional plate 31 and bottom plate 33 respectively hinged with two pieces of the lateral plate 32, two pieces of the bottom plate 33 are connected by the hinged piece 34, the hinged piece 34 is aligned with the midline of the directional plate 31, pull rod 35 is slidably arranged on the directional plate 31, one end of the pull rod 35 extends out the upper end of the guardrail body 1, and the other end is fixedly connected with the hinged piece 34, drive handle 36 is fixedly arranged on the top of the pull rod 35, one piece of the directional plate 31, two pieces of the lateral plate 32 and two pieces of the bottom plate 33 are enclosed to form trapezoidal body.

[0026] This utility model has a folding base 3 at the bottom of the guardrail body 1. By pulling the drive handle 36 upward, the pull rod 35 is pulled upward, which in turn pulls the hinge 34 in the middle of the base plate 33 upward, so that the base plate 33 folds inward and the two side plates 32 that are spread out also fold inward to complete the folding. The width of the folded base is the same as the width of the guardrail body 1. When the guardrail body 1 needs to be used, the drive handle 36 is pressed down, which allows the pull rod 35 to push the base plate 33 and the two side plates 32 to open up and form a trapezoidal base structure.

[0027] When the base is folded, the space occupied by the guardrail is significantly reduced when it is not in use or needs to be temporarily stored. This improves space utilization and reduces transportation and storage costs, whether for centralized storage in a warehouse or for loading onto vehicles during transport. The trapezoidal structure formed by the unfolded base provides excellent stability. The trapezoidal design allows the guardrail to distribute lateral forces evenly across the base, reducing the risk of tipping over. Furthermore, the base of this building road foundation pit safety protection device has a simple structure, and the folding base 3 is convenient to fold and support, offering high stability.

[0028] like Figure 4 and Figure 5 As shown, in order to ensure smoother folding and support of the folding base 3, a groove 21 is provided on the support column 2, and guide columns 22 are provided on both sides of the drive handle 36 to be slidably connected to the groove 21. The drive handle 36 is slidably connected to the upper part of the guardrail body 1 through the guide groove and guide column 22. At the same time, the guide groove and guide column 22 can ensure that when the drive handle 36 is pressed and pulled up, the drive handle 36 can maintain vertical up and down sliding and will not deviate, causing the pull rod 35 to interfere with the side wall of the guardrail body 1, resulting in jamming during the storage and support of the folding base 3.

[0029] like Figure 4 and Figure 5 As shown, to facilitate the storage of the folding base 3, a support spring 23 is provided in the slide groove 21. The support spring 23 is located below the guide post 22 and abuts against the guide post 22. A fixing pin 24 is provided on the guide post 22, and a fixing hole 25 communicating with the inside of the slide groove 21 is provided on the support post 21. The fixing pin 24 extends into the fixing hole 25 to fix the pull rod 35. When the folding base 3 is in the unfolded state, the fixing pin 24 is engaged outside the fixing hole 25 to ensure the stability of the folding base 3 in the unfolded state and prevent it from folding on its own. When it is necessary to store the folding base 3, the fixing pin 24 is pressed back into the fixing hole 25. At this time, the support spring 23 will automatically push the guide post 22 to drive the drive handle 36 and the pull rod 35 to move upward to store the folding base 3. The storage method relying on spring assistance is easier to operate, lowers the threshold of use, and improves the usability of the product and the user experience.

[0030] like Figure 1 and Figure 4 As shown, in order to ensure the stability of the folding base 3 supporting the ground, a threaded base 4 is provided on the outer side of the directional plate 31. The threaded base 4 is provided with a threaded cone 41. Threaded base 4 is provided at both ends of the outer side of each directional plate 31. Each threaded base 4 is provided with a threaded cone 41. The threaded cone 41 can be rotated and inserted into the ground. The design of the threaded cone 41 penetrating into the ground provides an additional anchoring point for the guardrail body 1, further enhancing the stability and safety of the entire protective structure.

[0031] like Figure 1 As shown, the LED warning screen 5 can display warning information with clear text, patterns, or flashing effects, such as "Danger Area, Do Not Approach" and "Construction Underway, Please Detour." Whether day or night, it attracts attention, allowing people to clearly see the danger warnings of the protected area from a distance, effectively preventing people from accidentally entering dangerous areas. The wide-range warning light 6 further enhances the warning range and visual impact by emitting strong light, especially in low-light or poor-visibility environments, such as construction sites at night or dimly lit warehouses. This makes it easier for people in the vicinity to notice the presence of the guardrail and the danger area it marks, greatly improving the overall warning effect. It also solves the problem that traditional guardrails usually rely on simple color markings or a few reflective strips for warning, which are often difficult to detect effectively in low light or complex environments, failing to clearly and accurately convey danger information.

[0032] The folding base 3 of this utility model can be quickly folded by pulling the drive handle 36. After folding, the width is the same as the guardrail body 1, which greatly reduces the overall space occupied when not in use or temporarily stored. Whether for centralized storage in warehouses or vehicle transportation, it can significantly improve space utilization and effectively reduce transportation and storage costs. The base unfolds into a trapezoidal structure. This design allows the guardrail to be subjected to lateral forces, which can be evenly distributed to all parts of the base, greatly reducing the risk of tipping over and providing reliable stability for pit protection. The support column 2 is provided with a sliding groove 21, and the drive handle 36 is provided with guide columns 22 on both sides for sliding connection with it. This ensures that the drive handle 36 can slide vertically up and down when pressed and pulled, avoiding interference between the pull rod 35 and the side wall of the guardrail body 1, and ensuring that the folding base 3 is stored and supported smoothly without jamming. A support spring 23 is provided in the sliding groove 21, a fixing pin 24 is provided in the guide column 22, and a fixing hole 25 is provided in the support column 2. When unfolded, the retaining pin 24 engages with the retaining hole 25 to ensure stability; when folded, the retaining pin 24 is pressed back into the retaining hole 25, and the support spring 23 automatically pushes the guide post 22, causing the drive handle 36 and pull rod 35 to move upward to complete the folding. This spring-assisted method lowers the barrier to use and improves product usability and user experience.

[0033] This invention solves the problem that in the prior art, the support legs used for support are usually fixed in structure and do not have a folding function, or even if they have a folding design, the folding operation is complicated and cumbersome and cannot achieve quick folding. This results in low space utilization of the transport vehicle when the protective device needs to be transported or stored, as the support legs occupy a large space, making it impossible to efficiently load more protective devices and increasing transportation costs.
