Description

Technical Field

[0001] This utility model relates to the field of construction site fencing technology, and in particular to a foldable construction site safety fencing structure. Background Technology

[0002] Construction site enclosures are measures taken to isolate the construction site from the external environment, making the construction site a relatively closed space. These include walls built with various masonry materials and protective structures made of various prefabricated panels.

[0003] Traditional construction site safety barriers are bulky, inconvenient to transport, and suffer from poor splicing stability and insufficient wind resistance. They are also prone to tipping over on soft soil or sloping sites. Furthermore, their splicing efficiency is low, with units connected by bolts. For example, the patent application CN27581171U shows that the installation time for a single unit is more than 10 minutes. To address these issues, we propose a foldable construction site safety barrier structure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a foldable construction site safety enclosure structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foldable construction site safety enclosure structure includes multiple baffles, with two baffles on the same side forming a group. Baffles in adjacent groups are mutually attracted, and two baffles in the same group are connected by a pivot. A limiting mechanism is installed on one side of each baffle, and two carrier boxes are provided between the two limiting mechanisms. A connecting box is connected to the upper end of each carrier box, and a driving mechanism is provided inside the connecting box. An insertion mechanism is provided inside each carrier box, with one end of the insertion mechanism connected to the driving mechanism and the other end of the insertion mechanism corresponding to the limiting mechanism. A reinforcing mechanism is provided on one side of each carrier box, and a suction cup is threaded onto the lower end of each baffle.

[0007] Preferably, a magnetic block is fixed on one side of the baffle, and two adjacent magnetic blocks attract each other.

[0008] Preferably, the limiting mechanism includes a mounting block fixed to one side of the baffle, and the mounting block has a plurality of insertion holes evenly spaced along the vertical direction.

[0009] Preferably, the driving mechanism includes a pull rod that passes through the connecting box, a handle is fixed to the upper end of the pull rod, a mounting plate is fixed to the lower end of the pull rod, springs are installed on both sides of the upper end of the mounting plate, the upper ends of the springs abut against the top inside the connecting box, and a moving rod is fixed to the lower end of the mounting plate.

[0010] Preferably, the insertion mechanism includes a connecting rod rotatably connected to both ends of the moving rod, a moving block rotatably connected to one end of the connecting rod, an insertion rod fixed to one end of the moving block, and an insertion rod on the same side penetrating the side wall of the carrier box and being inserted into one of the insertion holes, wherein the carrier box and the connecting box are connected through each other.

[0011] Preferably, the reinforcing mechanism includes a fixing member fixed to one side of the carrier box, a bolt is installed on the fixing member, and a support rod is provided through the bolt.

[0012] Preferably, the lower end of the baffle is threaded with a ground nail.

[0013] In this utility model, when it is needed for use, depending on the usage environment, a suction cup structure is used for hardened roads and a ground nail structure is used for soil surfaces. When arranging, the two baffles in the same group are unfolded, and the unfolding angle of the rotating shaft is degrees, so that they form an equilateral triangle. Then, the handle is pulled up and down to drive the pull rod, the mounting plate and the moving rod to move upward, compressing the spring. Through the drive of the connecting rod, the insertion rod is retracted into the carrier box. Then, the carrier box is placed between the two mounting blocks. When the handle is released, the insertion rod is inserted into the insertion holes at both ends under the drive of the spring's reset, so as to achieve a firm limiting and fixing. The support rod on one side is set as needed, which can further improve the stability and firmness of the support.

[0014] This utility model has the following advantages:

[0015] 1. Through triangular folding optimization, the storage volume is reduced by 58%, which not only reduces space occupation but also facilitates relocation;

[0016] 2. By using magnetic attraction and spring locking for the insertion rod, the resistance to lateral displacement of the connection point is improved, while also facilitating quick and easy installation. The time required for a single assembly is reduced from 8 minutes to 45 seconds, greatly improving efficiency.

[0017] 3. The triangular structure, combined with the use of reinforcement mechanisms, increases the overall rigidity and greatly enhances wind resistance.

[0018] In summary, this utility model solves the problems of limited functionality and poor adaptability of existing fencing, greatly improves the speed of installation, reduces space occupation, increases overall rigidity, and significantly enhances wind resistance. It is particularly suitable for complex working conditions requiring rapid deployment, such as subway construction and disaster relief. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figure 1-4 A foldable construction site safety enclosure structure includes multiple baffles 1, with two baffles 1 on the same side forming a group. Two adjacent groups of baffles 1 attract each other. A magnetic block 3 is fixed on one side of the baffle 1. Two adjacent magnetic blocks 3 attract each other and automatically lock upon contact, with a response time of <0.3s.

[0028] The two baffles 1 in the same group are connected by a rotating shaft with a rotation angle of 60 degrees, which can arrange the two baffles 1 in an equilateral triangle to improve their stability and balance;

[0029] A limiting mechanism is installed on one side of the baffle 1. The limiting mechanism includes a mounting block 4 fixed to one side of the baffle 1. The mounting block 4 has multiple insertion holes 7 at equal intervals along the vertical direction for locking and limiting, ensuring the firmness of the support.

[0030] Two carrier boxes 6 are provided between the two limiters. A connecting box 5 is connected to the upper end of the carrier box 6. A driving mechanism is provided inside the connecting box 5. The driving mechanism includes a pull rod 8 that passes through the connecting box 5. A handle 9 is fixed to the upper end of the pull rod 8. A mounting plate 13 is fixed to the lower end of the pull rod 8. Springs 10 are installed on both sides of the upper end of the mounting plate 13. The upper end of the springs 10 abuts against the top inside the connecting box 5. A moving rod 12 is fixed to the lower end of the mounting plate 13. The springs 10 are reset and adjusted by being driven by the pull rod 8.

[0031] The carrier box 6 is equipped with a plug-in mechanism, which includes a connecting rod 11 rotatably connected to both ends of the moving rod 12. One end of the connecting rod 11 is rotatably connected to a moving block 14, and one end of the moving block 14 is fixed with a plug rod 15. One plug rod 15 on the same side passes through the side wall of the carrier box 6 and is plugged into one of the plug holes 7. The carrier box 6 and the connecting box 5 are connected. The overall fixation is achieved by plugging the plug rod 15 into the plug hole 7. At the same time, the number of carrier boxes 6 can be selected as needed to fully ensure the reinforcement and support effect.

[0032] Furthermore, one end of the insertion mechanism is connected to the driving mechanism, and the other end of the insertion mechanism corresponds to the limiting mechanism. A reinforcing mechanism is provided on one side of the carrier box 6. The reinforcing mechanism includes a fixing member 16 fixed on one side of the carrier box 6. A bolt 17 is installed on the fixing member 16, and a support rod 18 is provided through the bolt 17. The support rod 18 provides flexible support and improves the overall stability. At the same time, the bolt 17 is used for connection, and it can be disassembled as needed to meet the needs of use or non-use.

[0033] The lower end of the baffle 1 is threaded with a suction cup 2 to meet the usage requirements of hardened pavement and improve the stability of the support on hardened pavement.

[0034] Example 2

[0035] Reference Figure 5 The difference between this embodiment 2 and embodiment 1 is that this embodiment 2 also includes a ground nail 19 threadedly connected to the lower end of the baffle 1. The support system using ground nail 19 can adapt to complex terrain with a slope of ≤15° and meet the support requirements of soft soil.

[0036] This utility model has been tested and found that the assembly time for a single unit has been reduced from 8 minutes to 45 seconds, the hinge life is ≥500 folds (passing GB / T2443 fatigue test), the support system can adapt to complex terrain with a slope of ≤15°10, a 6-person team can complete the construction of a 100m isolation zone within 10 minutes at the disaster relief site, and the triangular units can be combined to form 3D three-dimensional warning signs (such as a cone-shaped roadblock array) to improve the warning effect.

[0037] In this utility model, when it is needed for use, depending on the usage environment, a suction cup 2 structure is used for hardened road surfaces, and a ground nail 19 structure is used for soil surfaces. When arranging, the two baffles 1 in the same group are unfolded, and the unfolding angle of the rotating shaft is 60 degrees, so that they form an equilateral triangle. Then, the handle 9 is pulled up and down to drive the pull rod 8, the mounting plate 14 and the moving rod 12 to move upward, compressing the spring 10. Through the drive of the connecting rod 11, the insertion rod 15 is retracted into the bearing box 6. Then, the bearing box 6 is placed between the two mounting blocks 4. When the handle 9 is released, the insertion rod 15 is inserted into the insertion holes 7 at both ends under the reset drive of the spring 10, so as to achieve a firm limiting and fixing. The support rod 18 on one side is set as needed, which can further improve the stability and firmness of the support.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
